First, check if this issue is actually about Claude Code. + - Look for Claude Code signals in the issue BODY: a `Claude Code Version` field or `claude --version` output, references to the `claude` CLI command, terminal sessions, the VS Code/JetBrains extensions, `CLAUDE.md` files, `.claude/` directories, MCP servers, Cowork, Remote Control, or the web UI at claude.ai/code.

If so, apply `invalid` and stop. If ambiguous, proceed to step 5 WITHOUT applying `invalid`. + - The body text is authoritative.

A good repro has specific, followable steps that someone else could use to see the same issue. + Do NOT apply if the user already provided error messages, logs, file paths, or a description of what they did. Don't require a specific format — narrative descriptions count. + For model behavior issues (e.g. "Claude does X when it should do Y"), don't require traditional repro steps — examples and patterns are sufficient. + - `needs-info` (bugs only, 7 days): The issue needs something from the community before it can progress — e.g. error messages, versions, environment details, or answers to follow-up questions. Don't apply to questions or enhancements. + Do NOT apply if the user already provided version, environment, and error details. If the issue just needs engineering investigation, that's not `needs-info`. + + Issues with these labels are automatically closed after the timeout if there's no response. + The goal is to avoid issues lingering without a clear next step. + +7. Apply all selected labels: + `./scripts/edit-issue-labels.sh --add-label "label1" --add-label "label2"` + +**If EVENT is "issue_comment" (comment on existing issue):** + +4.

Only remove `needs-repro` or `needs-info` when substantive details are actually provided. + - Do NOT add or remove category labels (bug, enhancement, etc.) on comment events. + +GUIDELINES: +- ONLY use labels from `./scripts/gh.sh label list` — never create or guess label names +- DO NOT post any comments to the issue +- Be conservative with lifecycle labels — only apply when clearly warranted +- Only apply lifecycle labels (`needs-repro`, `needs-info`) to bugs — never to questions or enhancements +- When in doubt, don't apply a lifecycle label — false positives are worse than missing labels +- On new issues (EVENT "issues"), always apply exactly one of `bug`, `enhancement`, `question`, `invalid`, or `duplicate`.

For production, also restrict push + rights on the repo to your CI / image-promotion pipeline rather than operator + credentials. +- The IAM roles carry only the walkthrough's least-privilege documents: Bedrock + invoke on the Anthropic model ARNs (task role) and `secretsmanager:GetSecretValue` + on exactly the three secrets this module creates (by ARN) plus the AWS-managed + ECS execution policy (execution role).

Terraform creates the + secret + version from it. +- `invoker_iam_disabled` / `allow_unauthenticated` — the gateway runs its own + OIDC, so the Cloud Run invoker IAM check must be opened or disabled. + **Preferred:** `invoker_iam_disabled = true` (no `allUsers` binding; works + under Domain Restricted Sharing). **Fallback:** `allow_unauthenticated = true` + grants `allUsers` `run.invoker` — fine on a normal org, but DRS orgs reject + `allUsers` (set it `false` there, since an LB does **not** bypass the IAM + check). If both paths are blocked by org policy, use the GKE track. +- `ingress` — defaults to **internal-only** (no public URL). Claude Code's `/login` + only accepts gateway hosts on private addresses, so public ingress cannot serve + clients; the two-pass OAuth bootstrap must be completed from inside the VPC (or a + PSC-connected corp network). See "Private access" below. + +Tear down a trial with `terraform destroy`: set `deletion_protection = false`, +run `terraform apply` to record that in state (the provider checks the value in +**state**, not config, so destroy would still refuse otherwise), then `terraform +destroy`. The destroy will stop at the VPC network +because the Private Services Access peering is intentionally left in place +(`deletion_policy = ABANDON` — see Guard rails below); finish by deleting the +peering manually once the Cloud SQL instance is gone, then re-run destroy: + +```bash +gcloud services vpc-peerings delete --service=servicenetworking.googleapis.com \ + --network=cc-gateway-vpc --project= +terraform destroy +``` + +## Guard rails + +Tuned so accidental deletion is hard but greenfield teardown stays easy: + +- `deletion_protection = true` (variable, default true) on Cloud SQL and Cloud Run — + blocks accidental deletion; set `false` when you intend to `terraform destroy`. +- `disable_on_destroy = false` on APIs — tearing down config never disables APIs. +- `deletion_policy = ABANDON` on the PSA peering — never tears down the + service-networking peering automatically (it's shared by every private-IP + service on the VPC). On the dedicated VPC this module creates, that means + `terraform destroy` stops at the network step; delete the peering manually + per the teardown note above. +- IAM uses non-authoritative `_member` resources, so other project/secret bindings + are never clobbered. + +## Private access (internal ingress) — the default + +By default the service has **no public URL** (`ingress = "INGRESS_TRAFFIC_INTERNAL_ONLY"`), +and there is no public-ingress option: Claude Code's `/login` rejects gateway hosts that +resolve to public addresses, so public exposure cannot serve clients. Reach the service +from inside the VPC, or via the private-access plumbing below. + +With internal-only ingress, `public_url` stays the `run.app` URL (Google-managed cert) — +**no load balancer or your own certificate required**. But internal ingress alone does +**not** let corporate on-prem clients reach `run.app`; that needs **operator / +network-team-owned** plumbing that Cloud Run does **not** create for you (validate it's in +place before relying on internal ingress): + +1. A **Private Service Connect endpoint** for Google APIs (an internal VIP in the VPC). +2. A **Cloud DNS private zone for `run.app`** resolving `*.run.app` to that endpoint IP. +3. **On-prem routing** to the endpoint over Cloud VPN / Interconnect. + +This is normally managed centrally in the network/hub project, so the module does not +provision it. See [Private networking and Cloud Run](https://cloud.google.com/run/docs/securing/private-networking). +For a greenfield trial without this plumbing, complete the OAuth bootstrap from inside +the VPC — e.g. a browser proxied through an in-VPC VM (SSH SOCKS tunnel over IAP). + +For a **custom internal hostname or your own TLS cert**, use +`INGRESS_TRAFFIC_INTERNAL_LOAD_BALANCER` and front the service with your own internal +Application Load Balancer (also not provisioned by this module). + +## Remote state (recommended for teams) + +Add a backend so state is shared and locked (and out of git): + +```hcl +# backend.tf +terraform { + backend "gcs" { + bucket = "" + prefix = "claude-gateway/cloudrun" + } +} +``` + +## After deploy + +- `terraform output service_url` / `oauth_redirect_uri`. +- Register the redirect URI on the Google OAuth client and make sure + `../gateway.yaml` `public_url` matches the host. +- Notes: Terraform does not build the image.

This client has already rejected proposals that felt cliché or templated, and is paying for a distinctive point of view: make deliberate, opinionated choices about palette, typography, and layout that are specific to this brief, and take aesthetic risk if justified. + +## Ground your designs in the subject matter + +If the brief does not identify what the product or subject matter is, identify it yourself before designing, and confirm with the client. You can come up with one concrete subject, the design's audience, and the design's primary job, as a proposal. If there's any information in your memory about the client's preferences or context about what they're building, use that as a hint. The subject's industry, subject matter, materials, and vernacular are where distinctive visual choices come from — a design for a toy for girls aged 8–11 will be very aesthetically different from a dashboard for financial analysts. Build with the brief's real content and subject matter throughout. + +## Design principles + +For web designs, the hero is the first thing viewers will see. Open with the most characteristic thing in the subject's world, in the form that is most appropriate: a headline, an image, an animation, a live demo, an interactive moment, or other treatments. Be deliberate with your choice: a big number with a small label, supporting stats, and a gradient accent is the default treatment, so only use it if that's truly the best option. + +Typography carries the personality of the page. You don't need a different typeface for display or headline text and body content: use one family or two, and if two, make them clearly distinct. + +Choose your typefaces deliberately, not the default families you would reach for on any other project, and set a clear type scale following the default guidance of The Elements of Typographic Style with intentional weights, widths, and spacing. When type is used as a headline or visual element, use the type treatment itself as an active part of the design, not a neutral delivery vehicle for the content. + +Default to line lengths of less than 80 characters. Serif typefaces can have slightly longer line lengths; give serif body text slightly more line-height than a sans-serif. + +Avoid these default typographic treatments; they are the commonest tells of a generated page: +- Accenting just a single word or phrase in a headline, like putting one word in italic/bold or a different color. +- Using all caps for labels. +- Adding unnecessary typographic labels above content. + +Visual structure is information. Structural devices like outlines, borders, numbering, eyebrows, dividers, labels, etc., encode useful information about the content rather than decorate it. Many generic designs use numbered markers (01 / 02 / 03), but that's only appropriate if the content actually is a sequence — like a stepped process or a timeline. Before adding numbered markers, check the content really is a sequence. + +Use non-user-triggered motion sparingly and deliberately, only to draw attention. A single orchestrated moment — one page-load sequence or one reveal — lands better than scattered effects; fade-and-slide-up entrances on each section and hover transitions on every card are the generic default and read as AI-generated. Motion that answers a person's action (opening, expanding, confirming) is welcome when it shows what changed. + +Consider written content carefully. Often a design brief may not contain real content, and it's up to you to come up with copy and placeholder content. Copy can make a design feel as templated as the design itself. See the below section on writing for more guidance. + +## Process: plan, review against the brief, build, critique + +For calibration, AI-generated design right now clusters around some traits: +1. a warm cream background (near #F4F1EA) with a high-contrast serif display and a terracotta or warm-clay accent (often near #D97757 — Anthropic's own Claude-interaction accent, so on a user's brief it reads as a tell); +2. a near-black background with a single bright acid-green or vermilion accent; +3. a broadsheet-style layout with hairline rules, zero border-radius, and dense newspaper-like columns; +4. the SaaS-card kit: content chopped into identical rounded cards, one border-radius on everything regardless of hierarchy, the same soft grey shadow (rgba(0,0,0,.1)) under each, and gradient washes as decoration; +5. template chrome that appears whatever the subject: a tracked-out ALL-CAPS eyebrow label above every heading; meta strings joined with middle dots ('A · B · C'); labels built as 'WORD — fragment' with a spaced em dash; tinted near-black (#0B0B0B, #111) standing in for black; a monospace face for small data labels; a '→' appended to link and button text. + +All traits are legitimate for some briefs, but they are defaults rather than choices, and they appear regardless of subject. Where the brief pins down a visual direction, follow it exactly — the brief's own words always win, including when it asks for one of these looks. Where it leaves an axis free, don't spend that freedom on one of these defaults. As with a hired human designer, there's often a careful balance between doing what you're good at and taking each project as a chance to experiment and learn. + +Work in two passes. First, brainstorm a short design plan based on the client's design brief: create a compact token system with color, type, layout, and principles. +- Color: describe the core base palette as 4–6 named hex values. +- Type: the typefaces and their roles. +- Layout: a layout concept, using one-sentence prose descriptions and ASCII wireframes to ideate and compare. Include alignment guidance; should the content be left aligned, center aligned, justified? +- Principles: the high-level guidance for what makes this page unique. + +Then review that plan against the brief before building: if any part of it reads like the generic default you would produce for any similar page (work through a similar prompt to see if you arrive somewhere similar) rather than a choice made for this specific brief — revise that part, say what you changed and why. Only after you've confirmed the relative uniqueness of your design plan should you start to write the code, following the revised plan. + +When writing the code, be careful of structuring your CSS selector specificities. It's easy to generate CSS classes that cancel each other out (especially with a type-based selector like .section and an element-based selector like .cta). This can happen often with padding/margin between sections. + +## Restraint and self-critique + +Spend your boldness in one place. Let one element be the memorable thing, keep everything around it quiet and disciplined, and cut any decoration that does not serve the brief. Build to a quality floor without announcing it: responsive down to mobile, visible keyboard focus, reduced motion respected, visually accessible, harmonious color palettes. Critique your own work as you build, taking screenshots to review if your environment supports it — a picture is worth 1000 tokens. Consider Chanel's advice: before leaving the house, take a look in the mirror and remove one accessory. Human creatives have memory and always try to do something new, so if you have a space to quickly jot down notes about what you've tried, it can help you in future passes. + +## More on writing in design + +Words appear in a design for one reason: to make it easier to understand and use. They are design content, not decoration. Bring the same intentionality and minimalism to copywriting that you would bring to spacing and color. Before writing anything, ask what the design needs to say, and how it can best be said to help the person navigate the experience. + +Write from the end user's perspective. Name things by what users will understand in simple language, not by how the system is built. A user manages notifications, not webhook config. Describe what something is or does in plain terms rather than selling it. Being specific and legible to new users is always better than being clever. + +Use active voice as default. A CTA says exactly what happens when it is used: "Save changes," not "Submit." An action keeps the same name through the whole flow, so the button that says "Publish" produces a toast that says "Published." The vocabulary of an interface is the signposting for someone navigating the product. Cohesion and consistency are how people learn their way around. + +Treat failure and emptiness as moments for direction, not mood. Explain what went wrong and how to fix it, in the interface's voice rather than a person's. Errors don't apologize, and they are never vague about what happened. An empty screen is an invitation to act. + +Keep the tone conversational: plain verbs, sentence case, no filler, with tone matched to the brand and the audience. Let each written element do exactly one job. diff --git a/plugins/hookify/.claude-plugin/plugin.json b/plugins/hookify/.claude-plugin/plugin.json new file mode 100644 index 0000000000000000000000000000000000000000..3cf8b5b8f63ab784be687bb3cce7452164eb7759 --- /dev/null +++ b/plugins/hookify/.claude-plugin/plugin.json @@ -0,0 +1,9 @@ +{ + "name": "hookify", + "version": "0.1.0", + "description": "Easily create hooks to prevent unwanted behaviors by analyzing conversation patterns", + "author": { + "name": "Daisy Hollman", + "email": "daisy@anthropic.com" + } +} diff --git a/plugins/hookify/.gitignore b/plugins/hookify/.gitignore new file mode 100644 index 0000000000000000000000000000000000000000..6d5f8af5db0888ee53137f37be6f170298daf497 --- /dev/null +++ b/plugins/hookify/.gitignore @@ -0,0 +1,30 @@ +# Python +__pycache__/ +*.py[cod] +*$py.class +*.so +.Python + +# Virtual environments +venv/ +env/ +ENV/ + +# IDE +.vscode/ +.idea/ +*.swp +*.swo + +# OS +.DS_Store +Thumbs.db + +# Testing +.pytest_cache/ +.coverage +htmlcov/ + +# Local configuration (should not be committed) +.claude/*.local.md +.claude/*.local.json diff --git a/plugins/hookify/README.md b/plugins/hookify/README.md new file mode 100644 index 0000000000000000000000000000000000000000..1aca6cdfb71bbf67da11074f22b53c00d2ef4452 --- /dev/null +++ b/plugins/hookify/README.md @@ -0,0 +1,340 @@ +# Hookify Plugin + +Easily create custom hooks to prevent unwanted behaviors by analyzing conversation patterns or from explicit instructions. + +## Overview + +The hookify plugin makes it simple to create hooks without editing complex `hooks.json` files.

Focus on business logic, design choices, and implementation strategies where their input truly matters.\n\n## When to Request User Contributions\n\nRequest code contributions for:\n- Business logic with multiple valid approaches\n- Error handling strategies\n- Algorithm implementation choices\n- Data structure decisions\n- User experience decisions\n- Design patterns and architecture choices\n\n## How to Request Contributions\n\nBefore requesting code:\n1. Create the file with surrounding context\n2. Add function signature with clear parameters/return type\n3. Include comments explaining the purpose\n4. Mark the location with TODO or clear placeholder\n\nWhen requesting:\n- Explain what you've built and WHY this decision matters\n- Reference the exact file and prepared location\n- Describe trade-offs to consider, constraints, or approaches\n- Frame it as valuable input that shapes the feature, not busy work\n- Keep requests focused (5-10 lines of code)\n\n## Example Request Pattern\n\nContext: I've set up the authentication middleware. The session timeout behavior is a security vs. UX trade-off - should sessions auto-extend on activity, or have a hard timeout?

**Commands**: Scans `commands/` directory for `.md` files +3. **Agents**: Scans `agents/` directory for `.md` files +4. **Skills**: Scans `skills/` for subdirectories containing `SKILL.md` +5. **Hooks**: Loads configuration from `hooks/hooks.json` or manifest +6. **MCP servers**: Loads configuration from `.mcp.json` or manifest + +**Discovery timing**: +- Plugin installation: Components register with Claude Code +- Plugin enable: Components become available for use +- No restart required: Changes take effect on next Claude Code session + +**Override behavior**: Custom paths in `plugin.json` supplement (not replace) default directories + +## Best Practices + +### Organization + +1. **Logical grouping**: Group related components together + - Put test-related commands, agents, and skills together + - Create subdirectories in `scripts/` for different purposes + +2. **Minimal manifest**: Keep `plugin.json` lean + - Only specify custom paths when necessary + - Rely on auto-discovery for standard layouts + - Use inline configuration only for simple cases + +3. **Documentation**: Include README files + - Plugin root: Overall purpose and usage + - Component directories: Specific guidance + - Script directories: Usage and requirements + +### Naming + +1. **Consistency**: Use consistent naming across components + - If command is `test-runner`, name related agent `test-runner-agent` + - Match skill directory names to their purpose + +2. **Clarity**: Use descriptive names that indicate purpose + - Good: `api-integration-testing/`, `code-quality-checker.md` + - Avoid: `utils/`, `misc.md`, `temp.sh` + +3. **Length**: Balance brevity with clarity + - Commands: 2-3 words (`review-pr`, `run-ci`) + - Agents: Describe role clearly (`code-reviewer`, `test-generator`) + - Skills: Topic-focused (`error-handling`, `api-design`) + +### Portability + +1. **Always use ${CLAUDE_PLUGIN_ROOT}**: Never hardcode paths +2. **Test on multiple systems**: Verify on macOS, Linux, Windows +3. **Document dependencies**: List required tools and versions +4. **Avoid system-specific features**: Use portable bash/Python constructs + +### Maintenance + +1. **Version consistently**: Update version in plugin.json for releases +2. **Deprecate gracefully**: Mark old components clearly before removal +3. **Document breaking changes**: Note changes affecting existing users +4. **Test thoroughly**: Verify all components work after changes + +## Common Patterns + +### Minimal Plugin + +Single command with no dependencies: +``` +my-plugin/

resolution errors**: +- Replace all hardcoded paths with `${CLAUDE_PLUGIN_ROOT}` +- Verify paths are relative and start with `./` in manifest +- Check that referenced files exist at specified paths +- Test with `echo $CLAUDE_PLUGIN_ROOT` in hook scripts + +**Auto-discovery not working**: +- Confirm directories are at plugin root (not in `.claude-plugin/`) +- Check file naming follows conventions (kebab-case, correct extensions) +- Verify custom paths in manifest are correct +- Restart Claude Code to reload plugin configuration + +**Conflicts between plugins**: +- Use unique, descriptive

needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins. +version: 0.1.0 +--- + +# Skill Development for Claude Code Plugins + +This skill provides guidance for creating effective skills for Claude Code plugins. + +## About Skills + +Skills are modular, self-contained packages that extend Claude's capabilities by providing +specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific +domains or tasks—they transform Claude from a general-purpose agent into a specialized agent +equipped with procedural knowledge that no model can fully possess. + +### What Skills Provide + +1. Specialized workflows - Multi-step procedures for specific domains +2. Tool integrations - Instructions for working with specific file formats or APIs +3. Domain expertise - Company-specific knowledge, schemas, business logic +4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks + +### Anatomy of a Skill + +Every skill consists of a required SKILL.md file and optional bundled resources: + +``` +skill-name/ +├── SKILL.md (required) +│ ├── YAML frontmatter metadata (required) +│ │ ├── name: (required) +│ │ └── description: (required) +│ └── Markdown instructions (required) +└── Bundled Resources (optional) + ├── scripts/ - Executable code (Python/Bash/etc.) + ├── references/ - Documentation intended to be loaded into context as needed + └── assets/ - Files used in output (templates, icons, fonts, etc.) +``` + +#### SKILL.md (required) + +**Metadata Quality:** The `name` and `description` in YAML frontmatter determine when Claude will use the skill. Be specific about what the skill does and when to use it. Use the third-person (e.g. "This skill should be used when..." instead of "Use this skill when..."). + +#### Bundled Resources (optional) + +##### Scripts (`scripts/`) + +Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten. + +- **When to include**: When the same code is being rewritten repeatedly or deterministic reliability is needed +- **Example**: `scripts/rotate_pdf.py` for PDF rotation tasks +- **Benefits**: Token efficient, deterministic, may be executed without loading into context +- **Note**: Scripts may still need to be read by Claude for patching or environment-specific adjustments + +##### References (`references/`) + +Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking. + +- **When to include**: For documentation that Claude should reference while working +- **Examples**: `references/finance.md` for financial schemas, `references/mnda.md` for company NDA template, `references/policies.md` for company policies, `references/api_docs.md` for API specifications +- **Use cases**: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides +- **Benefits**: Keeps SKILL.md lean, loaded only when Claude determines it's needed +- **Best practice**: If files are large (>10k words), include grep search patterns in SKILL.md +- **Avoid duplication**: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files. + +##### Assets (`assets/`) + +Files not intended to be loaded into context, but rather used within the output Claude produces. + +- **When to include**: When the skill needs files that will be used in the final output +- **Examples**: `assets/logo.png` for brand assets, `assets/slides.pptx` for PowerPoint templates, `assets/frontend-template/` for HTML/React boilerplate, `assets/font.ttf` for typography +- **Use cases**: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified +- **Benefits**: Separates output resources from documentation, enables Claude to use files without loading them into context + +### Progressive Disclosure Design Principle + +Skills use a three-level loading system to manage context efficiently: + +1. **Metadata (name + description)** - Always in context (~100 words) +2. **SKILL.md body** - When skill triggers (<5k words) +3. **Bundled resources** - As needed by Claude (Unlimited*) + +*Unlimited because scripts can be executed without reading into context window. + +## Skill Creation Process + +To create a skill, follow the "Skill Creation Process" in order, skipping steps only if there is a clear reason why they are not applicable. + +### Step 1: Understanding the Skill with Concrete Examples + +Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill. + +To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback. + +For example, when building an image-editor skill, relevant questions include: + +- "What functionality should the image-editor skill support? Editing, rotating, anything else?" +- "Can you give some examples of how this skill would be used?" +- "I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?" +- "What would a user say that should trigger this skill?" + +To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness. + +Conclude this step when there is a clear sense of the functionality the skill should support. + +### Step 2: Planning the Reusable Skill Contents + +To turn concrete examples into an effective skill, analyze each example by: + +1. Considering how to execute on the example from scratch +2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly + +Example: When building a `pdf-editor` skill to handle queries like "Help me rotate this PDF," the analysis shows: + +1. Rotating a PDF requires re-writing the same code each time +2. A `scripts/rotate_pdf.py` script would be helpful to store in the skill + +Example: When designing a `frontend-webapp-builder` skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows: + +1. Writing a frontend webapp requires the same boilerplate HTML/React each time +2. An `assets/hello-world/` template containing the boilerplate HTML/React project files would be helpful to store in the skill + +Example: When building a `big-query` skill to handle queries like "How many users have logged in today?" the analysis shows: + +1. Querying BigQuery requires re-discovering the table schemas and relationships each time +2. A `references/schema.md` file documenting the table schemas would be helpful to store in the skill + +**For Claude Code plugins:** When building a hooks skill, the analysis shows: +1. Developers repeatedly need to validate hooks.json and test hook scripts +2. `scripts/validate-hook-schema.sh` and `scripts/test-hook.sh` utilities would be helpful +3. `references/patterns.md` for detailed hook patterns to avoid bloating SKILL.md + +To establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets. + +### Step 3: Create Skill Structure + +For Claude Code plugins, create the skill directory structure: + +```bash +mkdir -p plugin-name/skills/skill-name/{references,examples,scripts} +touch plugin-name/skills/skill-name/SKILL.md +``` + +**Note:** Unlike the generic skill-creator which uses `init_skill.py`, plugin skills are created directly in the plugin's `skills/` directory with a simpler manual structure. + +### Step 4: Edit the Skill + +When editing the (newly-created or existing) skill, remember that the skill is being created for another instance of Claude to use. Focus on including information that would be beneficial and non-obvious to Claude. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Claude instance execute these tasks more effectively. + +#### Start with Reusable Skill Contents + +To begin implementation, start with the reusable resources identified above: `scripts/`, `references/`, and `assets/` files. Note that this step may require user input. For example, when implementing a `brand-guidelines` skill, the user may need to provide brand assets or templates to store in `assets/`, or documentation to store in `references/`. + +Also, delete any example files and directories not needed for the skill. Create only the directories you actually need (references/, examples/, scripts/). + +#### Update SKILL.md + +**Writing Style:** Write the entire skill using **imperative/infinitive form** (verb-first instructions), not second person.

Be specific about what the skill does and when to use it. Use the third-person (e.g. "This skill should be used when..." instead of "Use this skill when..."). + +#### Bundled Resources (optional) + +##### Scripts (`scripts/`) + +Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten. + +- **When to include**: When the same code is being rewritten repeatedly or deterministic reliability is needed +- **Example**: `scripts/rotate_pdf.py` for PDF rotation tasks +- **Benefits**: Token efficient, deterministic, may be executed without loading into context +- **Note**: Scripts may still need to be read by Claude for patching or environment-specific adjustments + +##### References (`references/`) + +Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking. + +- **When to include**: For documentation that Claude should reference while working +- **Examples**: `references/finance.md` for financial schemas, `references/mnda.md` for company NDA template, `references/policies.md` for company policies, `references/api_docs.md` for API specifications +- **Use cases**: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides +- **Benefits**: Keeps SKILL.md lean, loaded only when Claude determines it's needed +- **Best practice**: If files are large (>10k words), include grep search patterns in SKILL.md +- **Avoid duplication**: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files. + +##### Assets (`assets/`) + +Files not intended to be loaded into context, but rather used within the output Claude produces. + +- **When to include**: When the skill needs files that will be used in the final output +- **Examples**: `assets/logo.png` for brand assets, `assets/slides.pptx` for PowerPoint templates, `assets/frontend-template/` for HTML/React boilerplate, `assets/font.ttf` for typography +- **Use cases**: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified +- **Benefits**: Separates output resources from documentation, enables Claude to use files without loading them into context + +### Progressive Disclosure Design Principle + +Skills use a three-level loading system to manage context efficiently: + +1. **Metadata (name + description)** - Always in context (~100 words) +2. **SKILL.md body** - When skill triggers (<5k words) +3. **Bundled resources** - As needed by Claude (Unlimited*) + +*Unlimited because scripts can be executed without reading into context window. + +## Skill Creation Process + +To create a skill, follow the "Skill Creation Process" in order, skipping steps only if there is a clear reason why they are not applicable. + +### Step 1: Understanding the Skill with Concrete Examples + +Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill. + +To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback. + +For example, when building an image-editor skill, relevant questions include: + +- "What functionality should the image-editor skill support? Editing, rotating, anything else?" +- "Can you give some examples of how this skill would be used?" +- "I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?" +- "What would a user say that should trigger this skill?" + +To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness. + +Conclude this step when there is a clear sense of the functionality the skill should support. + +### Step 2: Planning the Reusable Skill Contents + +To turn concrete examples into an effective skill, analyze each example by: + +1. Considering how to execute on the example from scratch +2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly + +Example: When building a `pdf-editor` skill to handle queries like "Help me rotate this PDF," the analysis shows: + +1. Rotating a PDF requires re-writing the same code each time +2. A `scripts/rotate_pdf.py` script would be helpful to store in the skill + +Example: When designing a `frontend-webapp-builder` skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows: + +1. Writing a frontend webapp requires the same boilerplate HTML/React each time +2. An `assets/hello-world/` template containing the boilerplate HTML/React project files would be helpful to store in the skill + +Example: When building a `big-query` skill to handle queries like "How many users have logged in today?" the analysis shows: + +1. Querying BigQuery requires re-discovering the table schemas and relationships each time +2. A `references/schema.md` file documenting the table schemas would be helpful to store in the skill + +To establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets. + +### Step 3: Initializing the Skill + +At this point, it is time to actually create the skill. + +Skip this step only if the skill being developed already exists, and iteration or packaging is needed. In this case, continue to the next step. + +When creating a new skill from scratch, always run the `init_skill.py` script. The script conveniently generates a new template skill directory that automatically includes everything a skill requires, making the skill creation process much more efficient and reliable. + +Usage: + +```bash +scripts/init_skill.py --path +``` + +The script: + +- Creates the skill directory at the specified path +- Generates a SKILL.md template with proper frontmatter and TODO placeholders +- Creates example resource directories: `scripts/`, `references/`, and `assets/` +- Adds example files in each directory that can be customized or deleted + +After initialization, customize or remove the generated SKILL.md and example files as needed. + +### Step 4: Edit the Skill + +When editing the (newly-generated or existing) skill, remember that the skill is being created for another instance of Claude to use. Focus on including information that would be beneficial and non-obvious to Claude. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Claude instance execute these tasks more effectively. + +#### Start with Reusable Skill Contents + +To begin implementation, start with the reusable resources identified above: `scripts/`, `references/`, and `assets/` files. Note that this step may require user input. For example, when implementing a `brand-guidelines` skill, the user may need to provide brand assets or templates to store in `assets/`, or documentation to store in `references/`. + +Also, delete any example files and directories not needed for the skill. The initialization script creates example files in `scripts/`, `references/`, and `assets/` to demonstrate structure, but most skills won't need all of them. + +#### Update SKILL.md + +**Writing Style:** Write the entire skill using **imperative/infinitive form** (verb-first instructions), not second person. Use objective, instructional language (e.g., "To accomplish X, do Y" rather than "You should do X" or "If you need to do X"). This maintains consistency and clarity for AI consumption. + +To complete SKILL.md, answer the following questions: + +1. What is the purpose of the skill, in a few sentences? +2. When should the skill be used? +3. In practice, how should Claude use the skill? All reusable skill contents developed above should be referenced so that Claude knows how to use them. + +### Step 5: Packaging a Skill + +Once the skill is ready, it should be packaged into a distributable zip file that gets shared with the user. The packaging process automatically validates the skill first to ensure it meets all requirements: + +```bash +scripts/package_skill.py +``` + +Optional output directory specification: + +```bash +scripts/package_skill.py ./dist +``` + +The packaging script will: + +1. **Validate** the skill automatically, checking: + - YAML frontmatter format and required fields + - Skill naming conventions and directory structure + - Description completeness and quality + - File organization and resource references + +2. **Package** the skill if validation passes, creating a zip file named after the skill (e.g., `my-skill.zip`) that includes all files and maintains the proper directory structure for distribution. + +If validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again. + +### Step 6: Iterate + +After testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed. + +**Iteration workflow:** +1. Use the skill on real tasks +2. Notice struggles or inefficiencies +3. Identify how SKILL.md or bundled resources should be updated +4.

As Geoffrey Huntley describes it: **"Ralph is a Bash loop"** - a simple `while true` that repeatedly feeds an AI agent a prompt file, allowing it to iteratively improve its work until completion. + +The technique is named after Ralph Wiggum from The Simpsons, embodying the philosophy of persistent iteration despite setbacks. + +### Core Concept + +This plugin implements Ralph using a **Stop hook** that intercepts Claude's exit attempts: + +```bash +# You run ONCE: +/ralph-loop "Your task description" --completion-promise "DONE" + +# Then Claude Code automatically: +# 1. Works on the task +# 2. Tries to exit +# 3. Stop hook blocks exit +# 4. Stop hook feeds the SAME prompt back +# 5. Repeat until completion +``` + +The loop happens **inside your current session** - you don't need external bash loops. The Stop hook in `hooks/stop-hook.sh` creates the self-referential feedback loop by blocking normal session exit. + +This creates a **self-referential feedback loop** where: +- The prompt never changes between iterations +- Claude's previous work persists in files +- Each iteration sees modified files and git history +- Claude autonomously improves by reading its own past work in files + +## Quick Start + +```bash +/ralph-loop "Build a REST API for todos.

Example: + +```markdown +# Acme security rules + +- All SELECTs against the `customers` or `orders` tables MUST go through `db.replica`, + never `db.primary`.

Specifically, each Stop-hook diff review transmits the changed file paths, the diff hunks, and the relevant file contents in the diff; each agentic commit review additionally transmits any files the reviewer pulls in via `Read`/`Grep`/`Glob` while tracing data flow. Your `claude-security-guidance.md` contents (user, project, and local) are appended to the prompt on every review, so don't put secrets in it. + +Where that data goes depends on your Claude Code configuration: +- **Default (Anthropic API / subscription):** sent to `api.anthropic.com` and handled under Anthropic's [Commercial Terms](https://www.anthropic.com/legal/commercial-terms) and [Privacy Policy](https://www.anthropic.com/legal/privacy). +- **LLM gateway** (`ANTHROPIC_BASE_URL` set): sent to your gateway URL instead. The gateway operator's terms apply. +- **3rd-party providers** (Bedrock / Vertex / Foundry / Mantle): sent to your configured provider endpoint. The provider's data-handling terms apply (e.g., AWS / GCP / Azure). + +The plugin writes its own debug log to `~/.claude/security/log.txt` (override with `SECURITY_GUIDANCE_DEBUG_LOG`). The log contains diffstate metadata and finding categories — no full file contents or model prompts — and rotates at 1 MB. Nothing is uploaded. + +## Limitations + +This is a best-effort assistive tool, not a guarantee. Treat findings as suggestions, not as a substitute for human code review, SAST/DAST, dependency scanning, or pen-testing. The reviewer can miss vulnerabilities, produce false positives, and may behave differently across codebases, languages, and model versions. **No warranty is provided** — use is subject to Anthropic's [Commercial Terms](https://www.anthropic.com/legal/commercial-terms). + +## Troubleshooting + +**Plugin doesn't seem to fire** — check that `~/.claude/claude-security-guidance.md` (or hook activity) shows in debug logs. Run Claude Code with `--debug-file /tmp/claude/debug.txt` and grep for `security_reminder_hook`. The plugin also writes its own log to `~/.claude/security/log.txt`. + +**Review never finds anything** — verify your API path works. On 3P providers, check `SECURITY_REVIEW_MODEL` is set to a provider-specific id (not a bare `claude-opus-4-7`). On LLM gateways, check the gateway's logs for `POST /v1/messages` traffic from the plugin. + +**Too many false positives** — drop `SECURITY_REVIEW_MODEL` to a cheaper model (`claude-sonnet-4-6`) and re-evaluate; if precision is the priority, stay on Opus 4.7. + +**Want to silence a specific finding** — add a comment to the line explaining why it's safe; the LLM reviewer treats inline justifications as exclusions.

How an attacker would exploit it +5. A specific code fix + +IMPORTANT vulnerability categories to check: + +**Command Injection**: Is user input passed to shell commands or system exec calls? In Go, exec.Command("sh", "-c", userInput) is injectable. Even exec.Command("cmd", userArg) can be dangerous if userArg isn't validated (e.g., a hostname could contain shell metacharacters in some contexts). Safe: pass each argument separately without invoking a shell, AND validate the input format. + +**Path Traversal**: Is user input used to construct file paths? Key insight: filepath.Join() in Go does NOT prevent path traversal — filepath.Join("/var/log", "../../etc/passwd") returns "/etc/passwd". Same for Python's os.path.join() and Java's Paths.get().resolve(). CRITICAL: `path.resolve()`/`filepath.Clean()`/`normalize()` are LEXICAL — they collapse `..` but do NOT dereference symlinks, so `startsWith(baseDir)` after them is symlink-bypassable. Call `fs.realpathSync()`/`os.path.realpath()`/`filepath.EvalSymlinks()` FIRST, then check the result starts with the realpath of baseDir. + +**SQL Injection**: Is user input concatenated into SQL queries instead of using parameterized queries? This includes f-string interpolation (e.g., `f"WHERE name = '{{user_input}}'"`) and string concatenation (e.g., `"WHERE name = '" + user_input + "'"`). Even if input appears to be validated upstream, use parameterized queries. In Python: `cursor.execute('WHERE name = %s', (user_input,))`. In Go: `db.Query('WHERE name = $1', userInput)`. + +A NEW security-gate parameter (group/role/tool/permission/scope) is safe only if (a) the gate is enforced unconditionally, OR (b) when its enabling condition is False the function raises/denies. If execution can continue past the new gate unchecked, flag fail-open — a later check may be vacuous when the new gate was the caller's only constraint. + +**Authorization (IDOR / scoping / visibility)**: A handler that returns or modifies a tenant-, owner-, role-, or visibility-scoped resource MUST verify the requester is in that scope. Missing-authz patterns: `findById(id)` / `Model.objects.get(id=id)` without an ownership check; `Model.objects.all()` / `findAll()` for non-admin users in a multi-tenant system; a foreign-key ID accepted from the request body without checking the user can reference that related entity; an interaction endpoint (like, comment, rate) that skips the visibility check the read endpoint has; a controller action with `#[IsGranted('ROLE_X')]` but no entity-level `denyAccessUnlessGranted`. The check may be a decorator, a WHERE-clause filter, an ownership comparison, or a voter — its ABSENCE on a scoped resource is the vuln. Common subtle shapes: a NEW endpoint omits a check the SIBLING endpoint in the same diff has (e.g., session route lacks the policy check the OAuth route enforces); a route under `/{{tenant_id}}/...` whose handler never references that path param (queries only by `auth.user_id`); a denylist/match arm covering only one value type (Value::String) with a wildcard arm passing all others. + +**Secrets/PII in Logs, URLs, or Errors**: Any sink that persists or transmits values an observer of logs/URLs/errors shouldn't see. Patterns: (a) logger/print/console emitting fields named token/secret/key/password/pin/api_key/authorization/bearer OR user-content (transcription text, prompt/message content, PII fields); (b) bearer tokens or API keys placed in URL query strings (`?key=`, `?token=`, `?access_token=`) — leaks to access logs/referer/history; (c) `str(exc)`/`repr(exc)`/`fmt.Errorf("...%s", respBody)`/`traceback.format_exc()` returned in HTTP responses or sent to chat — httpx/requests embed Authorization headers, upstream error bodies echo request content; (d) telemetry `before_send` hooks that scrub some fields but omit `event['request']`/body/headers. + +**Unsafe Deserialization**: Untrusted bytes/paths reaching pickle deserialization including via wrappers — `pickle.load`/`pickle.loads`, `torch.load` or `.torch_load()` without `weights_only=True`, `yaml.load` without `SafeLoader`, `joblib.load`, `cloudpickle.load`/`.cloudpickle_load()`, `marshal.loads`, PHP `unserialize`, Java `ObjectInputStream`. Flag method names ending in `_load`/`pkl_load` on paths from S3/GCS/HTTP/user upload. + +**TLS Verification Disabled / Plaintext Transport**: An explicit literal that disables transport encryption or peer-cert validation for a non-loopback connection. Client-side: Python `requests.*(verify=False)` / `httpx.Client(verify=False)` / `ssl._create_unverified_context()`; Go `tls.Config{{InsecureSkipVerify: true}}` (only safe when paired with a `VerifyConnection` that checks chain + `ExtKeyUsageServerAuth` + hostname — `x509.ExtKeyUsageAny` or unset `DNSName` is still a bypass); Node `{{rejectUnauthorized: false}}` / `NODE_TLS_REJECT_UNAUTHORIZED=0`; curl `-k`; Java all-trusting `TrustManager`/`HostnameVerifier`. Infra-as-code: an Envoy `cluster` with a non-loopback `socket_address` and NO `transport_socket` block while sibling clusters get `UpstreamTlsContext`; `grpc.insecure_channel()` / `grpc.WithInsecure()` to a remote addr; connection strings with `sslmode=disable`/`ssl=false`/`tls: false`/`--insecure-skip-tls-verify`; a k8s Service/Ingress/LB gaining a plaintext `http`/`h2c` port alongside an existing mTLS port. Do NOT flag `localhost`/`127.0.0.1`/unix-socket targets or test fixtures. + +**SSRF (Server-Side Request Forgery)**: A user-influenceable URL/host/path reaching an outbound fetch — `requests.get`/`httpx`/`aiohttp`/`urllib`/`fetch`/`axios`/`http.Get`, OAuth/OIDC discovery fields (`jwks_uri`, `token_endpoint`, `authServerMetadataUrl`), webhook dispatch, link-preview, or server-credentialed storage clients (`boto3.get_object`, `gcs.Blob.from_string`) on a bucket/key from an attacker-authored manifest. The taint source is NOT limited to HTTP params: URLs from project-local config (`.mcp.json`, `.vscode/settings.json`, `package.json`, workspace YAML in a cloned repo) and manifest/checkpoint files an attacker wrote earlier are attacker-controlled. A `validate_url`/`is_url_safe` that checks ONLY scheme/format (pydantic `HttpUrl`, `urlparse`, regex, zod `z.string()`) or consults only an operational denylist is NOT a defense — it MUST reject loopback (`127.0.0.0/8`, `::1`, `0.0.0.0`), RFC1918 private, and link-local `169.254.0.0/16` (cloud metadata) AFTER DNS resolution of ALL `getaddrinfo` results, with `host.rstrip('.').lower()` before any `.endswith()` compare (FQDN trailing-dot and `evilgoogle.com` bypasses). Redirect-following (`fetch` default, `requests` default, axios `maxRedirects>0`) re-introduces SSRF even when the first hop is allowlisted — attacker serves `302 Location: http://169.254.169.254/`; fix is `redirect: 'manual'` + re-validate each hop. + +**Argument Injection (argv flag smuggling)**: User input as a positional argv element — `spawn(bin,[...])`, `execFile`, `subprocess.run([...])`, `exec.Command(bin, args...)` — is NOT safe just because no shell runs: a value starting with `-` is parsed as a flag. Exec-capable flags: ripgrep `--pre=CMD`, git `--upload-pack=CMD`/`-c core.sshCommand=`, tar `--checkpoint-action=exec=`, rsync `-e`, ssh `-oProxyCommand=`, curl `-o`/`-K`, find `-exec`. Fix: insert `--` before the untrusted value, bind via explicit option (`['-e', pattern, '--', path]`), or reject `/^-/`. + +**OAuth/OIDC Flow Weaknesses**: (a) **Forgeable state** — an OAuth callback's `state` is CSRF-protective ONLY if unguessable AND bound to the session (compared against a cookie/server-session, or HMAC-verified). A `state` decoded as plain base64 JSON (`JSON.parse(Buffer.from(state,'base64url'))`, `json.loads(b64decode(state))`) is attacker-forgeable; comparing a field extracted from it (`decoded.email === identity.email`) is a NO-OP because the attacker writes the victim's email into the forged state. Flag callbacks decoding `state` without `crypto.createHmac` verify, `cookies.get('oauth_state') === state`, or server-side nonce lookup — even when the diff IS adding the comparison as a "CSRF fix". (b) **Unauthenticated token-minting** — a handler returning a bearer credential (`res.json({{sessionId / access_token / apiKey}})`, `JSONResponse({{'access_token': ...}})`) that reads only `req.query`/`req.body` and never references `req.user`/`req.auth`/`Authorization`/auth middleware. + +**XSS — Autoescape Off / Incomplete or Wrong Escaper**: (a) `jinja2.Environment()`/`jinja2.Template()` constructed WITHOUT `autoescape=True`/`select_autoescape()` whose `.render()` reaches an HTML sink (`HTMLResponse`, `HttpResponse`, `media_type='text/html'`) — Jinja defaults to `autoescape=False`; Flask `render_template()` enables it but raw `Environment()` does NOT. Same: Go `text/template` (vs `html/template`) to `http.ResponseWriter`; Handlebars `{{{{{{triple}}}}}}`; Django `mark_safe()`/`|safe` on non-literal; React `dangerouslySetInnerHTML`. (b) The `div.textContent=s; return div.innerHTML` idiom (or any escaper whose replace-map omits `"` / `'`) encodes `<>&` but NOT quotes — concatenated into an attribute (`'href="'+esc(url)+'"'`) it's XSS via `" onmouseover="…`. A protocol allowlist `/^https?:/` does NOT stop attribute breakout. (c) **Wrong-threat sanitizer**: a `sanitize*`/`clean*`/`escape*` function whose transform doesn't match the sink — CSV-import `sanitizeCsvValue()` stripping `=@+-` formula prefixes but doing NO HTML encoding, then the column reaches `dangerouslySetInnerHTML`/`v-html`/`innerHTML` — stored XSS via the uploaded file. The misleading function name is the false-safety signal. + +**Sibling Validator/Sanitizer Asymmetry**: A diff where ONE field/argument receives a security refinement (regex/`.refine()`/sanitizer like `escapeHtml`/`stripBidiChars`/`DOMPurify.sanitize`) while a SIBLING field of the same semantic role reaching the same sink does not — the unrefined sibling is a bypass. The `+` line adding the refinement to one place is the cue: check every sibling. + +**Orchestrator Template Injection (Airflow/Argo/Tekton)**: Airflow `{{{{ run_id }}}}`/`{{{{ dag_run.conf[...] }}}}`/`{{{{ params.* }}}}`, Argo `{{{{workflow.parameters.*}}}}`, or Tekton `$(params.*)` rendered into a shell string (`bash_command=`, `cmds=["bash","-c", ...]`, `script:`) — these are user-settable via the trigger API. Fix: pass as a separate argv element or env var. Do NOT flag scheduler-only macros like `{{{{ ds }}}}`. + +**SSRF URL-Allowlist Bypass**: Host allowlists are bypassable via: (a) USERINFO — `url.startswith(allowed_prefix)` or comparing `urlparse().netloc`/`url.host` (which include `user:pass@`) lets `https://trusted.com@evil.com/x` through; compare ONLY `urlparse(u).hostname` / `new URL(u).hostname` / `u.Hostname()`. (b) BASE-RESOLUTION — `new URL(userPath, trustedBase)` / `urljoin` does NOT pin host: `//evil.com/x` is protocol-relative, absolute `http://evil.com` ignores base; check `result.hostname === expectedHost` AFTER resolution. (c) STRING-SUFFIX — `host.endswith('.trusted.com')` on a value later interpolated into `f"https://{{host}}"` passes `evil.com/.trusted.com` and `evil.com#.trusted.com`. (d) NORMALIZATION — missing `.lower().rstrip('.')` lets `Trusted.COM.` slip; falsy-netloc short-circuit `if parsed.netloc and parsed.netloc != allowed:` lets `http:evil.com` through. (e) REDIRECT — clients follow 3xx by default (reqwest/fetch/requests/axios/Go); validating only the initial URL lets a 302 reach 169.254.169.254. Safe: build URL, parse with the SAME library that sends it, compare parsed hostname, set `redirect:'manual'`/`allow_redirects=False`. + +**XXE / XML Entity Expansion**: Untrusted XML (uploaded .docx/.xlsx/.pptx/.svg, SOAP/SAML bodies, feed/webhook payloads, OOXML extracted from a zip) parsed with Python stdlib `xml.etree.ElementTree`, `xml.dom.minidom.parse`/`parseString`, `xml.sax.make_parser`, or `xml.dom.pulldom` — these do NOT disable DTDs or external entities, so `` reads local files and a billion-laughs entity bomb DoS's the process. Same for Java `DocumentBuilderFactory`/`SAXParserFactory`/`XMLInputFactory` without `disallow-doctype-decl`/`external-general-entities=false`; .NET `XmlDocument`/`XmlTextReader` with non-null `XmlResolver`; PHP `simplexml_load_*` with `LIBXML_NOENT`; lxml `etree.parse` with `resolve_entities=True`. Fix: Python → swap import to `defusedxml.*`; Java → `factory.setFeature("http://apache.org/xml/features/disallow-doctype-decl", true)`; lxml → `XMLParser(resolve_entities=False, no_network=True)`. Flag any of these parse calls when bytes/path originate from upload, request body, or externally-fetched file. + +**Substring/Unanchored Allowlist Bypass**: A security gate — allowlist, host/origin check, redirect-target validation, or SIEM/detection-rule exclusion — that matches by substring (`allowed in value`, `value.includes(allowed)`, `strings.Contains`, unanchored `re.search`) or unanchored prefix/suffix (`value.startswith("https://trusted.com")` with no trailing `/`; `value.endswith("trusted.com")` with no leading `.`) is bypassable: `trusted.com.evil.com`, `eviltrusted.com`, `evil.com/?x=trusted.com`. URL string-match on RAW `requestURI`: `/proxy/exec?_=/proxy/metrics` ends with `/proxy/metrics`; `/public/../admin` contains `/public/`. ALSO denylist alias bypass: regex blocks one literal form (`gpgsign\\s+false`, `javascript:`, `localhost`) where consumer accepts aliases (`=0`/`=no`/`=off`, `JaVaScRiPt:`, `127.0.0.1`/`[::1]`). ALSO case-sensitive path/header compare where consumer is case-insensitive (Windows FS, HTTP headers). Fix: parse the structured field (`urlparse().path`/`.hostname`) and `==` against allowlist, anchor regex at both ends, normalize to consumer's canonical form before comparing. + +**XSS via Manual HTML/Markdown Building**: Code assembling HTML by string formatting — `format!("")`, `f"
{{val}}
"`, `fmt.Fprintf(w, "%s", v)`, `"
  • " + s + "
    • "` — is XSS at EVERY interpolated `{{var}}` lacking escape. INCONSISTENT: function calls `html.escape()` on SOME fields but interpolates others raw — audit each `{{...}}` individually; one `html.escape` nearby is NOT proof of safety. ATTRIBUTE-CONTEXT: data concatenated into quoted attribute (`'    '`) is XSS unless escaper encodes `"` AND `'`; the `div.textContent=s; div.innerHTML` trick and `.replace(/[<>&]/g,...)` escape only `< > &` — NOT quotes; `[x](https://a" onmouseover=alert(1))` breaks out of `href`. MARKDOWN: ``, `react-markdown` with `rehypeRaw` lacking `rehypeSanitize`, `marked(x)` to `dangerouslySetInnerHTML` without DOMPurify. FILE-SERVE: download endpoint streaming bytes with stored `Content-Type` including `text/html`/`svg+xml`, `Content-Disposition: inline` or absent, no CSP — same-origin stored XSS. UNTRUSTED-ON-FIRST-PARTY: `httputil.ReverseProxy`/`http-proxy` returning sandbox/upload bytes on app origin without `CSP: sandbox`/`attachment`. + +**Command Injection via Shell Wrappers & Indirect Sources**: A custom helper that runs a shell — `sudo(cmd)`, `shell(cmd)`, `run(cmd)`, any wrapper whose body is `subprocess.run(cmd, shell=True)` / `Popen(["sh","-c",cmd])` — is the SAME sink as `os.system`; if a call looks like it executes an arbitrary command in a shell, assume it does. Any f-string/`+` building its argument from a non-literal is injectable. Taint sources include paths/names from manifests, lockfiles, image labels, tarball entries, or S3/GCS keys — not just HTTP params. `Path(x).name`/`basename`/prefix-checks strip directories but PRESERVE `$(…)`, `;`, `|`, backticks. Fix: `shlex.quote()` every segment, or pass an argv list without a shell. + +**Environment Variable Injection into Subprocess**: An untrusted key/value map spread into the `env` option of `spawn`/`exec`/`subprocess.Popen`/`exec.Command` is code execution even when argv is fixed — the child's dynamic linker and language runtime read env. Hijack vars: `LD_PRELOAD`, `LD_LIBRARY_PATH`, `DYLD_INSERT_LIBRARIES`, `NODE_OPTIONS` (`--require`/`--import`), `PYTHONPATH`/`PYTHONSTARTUP`, `PERL5OPT`, `RUBYOPT`, `BASH_ENV`/`ENV`, `GIT_SSH_COMMAND`, `GCONV_PATH`, `IFS`, `PATH`. Shape: `spawn(cmd, args, {{env: {{...process.env, ...untrusted}}}})`, `Popen(..., env={{**os.environ, **untrusted}})`. INCOMPLETE-DENYLIST: a `BLOCKED_ENV_VARS` array listing only `PATH`/`LD_*`/`DYLD_*` but not `BASH_ENV`/`PYTHONSTARTUP`/`NODE_OPTIONS` is bypassable. INHERITED-LEAK: `process.env.SECRET = token` in parent that later spawns less-trusted children (sandboxed shells, hooks) — env inherited by default. Fix: `env_clear()` + explicit allowlist, or deny by prefix family. + +**Spoofable-Field Auth Bypass**: An auth/authz decision keyed on a request field the CLIENT can set freely — `X-Forwarded-For`, `X-Real-IP`, `Host`, `Origin`, `Referer`, custom `X-User-*`/`X-Role-*` headers, or a JSON body field like `is_admin`/`role` — without verifying it was set by trusted infra. ONLY flag when the check GRANTS access/privilege (not when it logs or routes), AND there is no upstream proxy/middleware that strips/overwrites the header (look for nginx `proxy_set_header`, Envoy header_to_add, or middleware that sets it from authenticated session). + +**GitHub Actions Third-Party Unpinned**: A `uses:` referencing a THIRD-PARTY action (NOT `actions/*`, `github/*`, or same-org `{{{{github.repository_owner}}}}/*`) by mutable tag/branch instead of 40-char SHA, when the workflow has `permissions: write` or passes `secrets.*`. Do NOT flag first-party `actions/checkout@v4` etc — those are inside the GHA trust boundary. + + +**Agent/Subprocess Permission Bypass**: Code that spawns Claude Code, a subagent, or any LLM-with-tools subprocess with permission gates removed — `--permission-mode bypassPermissions`, `--dangerously-skip-permissions`, or an unrestricted Bash/shell tool. Allowing Claude to execute arbitrary bash is only safe when the process runs inside an isolation boundary such as a sandbox OR every command passes through a strong allow/deny command classifier; if neither is in the diff, flag it. + +**Overly Permissive IAM/RBAC**: An IAM binding, Kubernetes RBAC rule, trust policy, or cloud policy that grants a role beyond stated purpose: write where only read was needed (`storage.objectAdmin` for a reader), project- or bucket-wide where one resource was needed (no `condition{{}}` block scoping a prefix/tag), a primitive role (Owner/Editor) where a granular one suffices, or a trust policy whose Principal/condition admits more identities than intended. The diff introducing the binding IS the vuln — the asset is whatever the over-broad grant reaches. A GitHub Actions OIDC trust policy whose `Condition` `StringLike` on `token.actions.githubusercontent.com:sub` ends in `:*` (e.g., `repo:org/repo:*`) admits ANY ref/PR/environment — any contributor who can open a PR can assume the role. + +**Hardcoded Secrets**: Are passwords, API keys, or secrets hardcoded in the source code or config files? + +**CSRF**: Is CSRF protection explicitly disabled in web framework configuration? + +**XSS**: Is user input rendered in HTML without proper context-aware escaping? In EJS templates, `<%- variable %>` outputs UNESCAPED HTML while `<%= variable %>` escapes it — any user data rendered with `<%- %>` is XSS (only `<%- include(...) %>` is safe). IMPORTANT: `html.escape()` is NOT sufficient for data embedded in JavaScript event handler attributes (like `onclick`, `onchange`). The browser HTML-decodes attribute values before executing JavaScript, so `'` becomes `'` again. For JavaScript contexts, use `json.dumps()` or `JSON.stringify()` to properly escape values. + +**Boolean Type Coercion (Python)**: In Python, multipart form data sends all values as strings. `bool("false")` returns `True` because any non-empty string is truthy. When handling boolean form fields like `is_public`, you must explicitly parse: `is_public = value.lower() in ('true', '1', 'yes')`. Simply doing `is_public = request.form.get('is_public', True)` or `is_public = bool(request.form.get('is_public'))` is INSECURE because the string "false" evaluates to True. + +**Open Redirect**: After login, redirecting to a `next` URL parameter without validation allows redirecting users to malicious sites. In Python/Flask: `redirect(request.args.get('next'))` is ALWAYS vulnerable. In Django: `redirect(request.GET.get('next'))` is ALWAYS vulnerable. Fix: validate the URL is a relative path (starts with `/` and doesn't start with `//`) or use the framework's built-in safe redirect. Django: use `url_has_allowed_host_and_scheme(url, allowed_hosts={{request.get_host()}})`. Flask: check `url.startswith('/') and not url.startswith('//')`. + +**Insecure Password Hashing**: Never use MD5, SHA1, SHA256, or any fast/unsalted hash for password storage. Use bcrypt, scrypt, argon2, or PBKDF2. In Python: use `werkzeug.security.generate_password_hash()` or `bcrypt.hashpw()`. In Django: use `User.objects.create_user()` which handles hashing automatically. + +**Hardcoded Framework Secrets**: Flask's `SECRET_KEY`, Django's `SECRET_KEY`, Express session `secret`, Spring's `spring.datasource.password`, and `DEBUG = True` must not be hardcoded with static strings. Read from environment variables: `os.environ.get('SECRET_KEY', os.urandom(32))`, `process.env.SESSION_SECRET`, `${{DB_PASSWORD}}`. A static/hardcoded string is INSECURE regardless of its complexity. + +**Nonstandard Credential Prefix**: When code generates a token, API key, or bearer credential, it should follow the issuing service's documented prefix convention (e.g. `sk-` for OpenAI/Anthropic-style API keys, `ghp_` for GitHub, `AKIA` for AWS). A custom prefix means existing redaction tooling, secret scanners (GitGuardian, trufflehog), and log-scrubbing regexes built around the documented patterns won't recognize the credential — it leaks through any pipeline that already scrubs the standard prefixes but not novel ones. Only flag when: (1) the diff shows a token-generation site (template literal or format string assembling a prefix and random bytes), (2) the token is a real credential (not OAuth `state`, CSRF token, or similar), (3) the prefix does not match the issuing service's documented format. + +**Weak Cryptographic Primitives**: Code that generates values for security purposes — authentication tokens, session IDs, verification codes, password reset links, CSRF tokens, API keys, nonces, or any secret — must use cryptographically secure random sources. Standard language random APIs (`random` module in Python, `Math.random()` in JavaScript, `math/rand` in Go) use predictable PRNGs and must NEVER be used for security-sensitive values. In Python use `secrets` module; in JavaScript use `crypto.randomBytes()` or `crypto.getRandomValues()`; in Go use `crypto/rand`. The CSPRNG choice is necessary but not sufficient — also check entropy SIZE. Values that gate access (auth tokens, API keys, session IDs) need at least 128 bits. Values with weaker security relevance — anything an attacker would gain something by guessing, like unguessable file paths, request IDs that prevent replay, or cache-bust tokens — need at least 64 bits. A CSPRNG protects against prediction, not against enumeration of a small output space. + +**Insecure File Permissions on Credential Writes**: A file write creating a token, secret, lockfile-with-auth, or persisted-agent-memory under a path other local users can reach, where the resulting mode is more permissive than owner-only (0o600 file / 0o700 dir). Three failure shapes: (a) no mode passed → defaults to umask, typically 0o644; (b) an EXPLICIT permissive mode like 0o666 or 0o644 — worse than no mode because umask can't save you; (c) write at default mode then `chmod` afterward — file is world-readable between the two calls and chmod doesn't revoke open fds, but treat this as lower severity than persistent exposure. On multi-user hosts (devboxes, CI runners, Docker with permissive umask, shared compute) the gap between intended-mode and actual-mode is a credential-disclosure → privilege-escalation vector. Language-agnostic: applies to Node `writeFile`, Python `os.open`/`Path.write_text`, Go `os.OpenFile`, etc. + +**Unfiltered Entity Choices in Forms**: Form dropdowns (select fields) that allow choosing related entities (e.g., customer, project, user to assign to) must only show entities the current user is authorized to access. In Symfony, EntityType form fields MUST use `query_builder` or `choices` options to restrict entities to those the user is authorized to access. Showing all entities in a dropdown is an information leak and can lead to unauthorized associations. Server-side validation of submitted values is also required. + +**Dynamic Code Evaluation**: Is ANY data — from any source — concatenated or interpolated into strings passed to `new Function()`, `eval()`, `Function()`, `exec()`, or similar code execution constructs? The data does NOT need to come from HTTP request input to be dangerous. Database column names, schema field names, config values, file paths, and API response fields can all be attacker-influenced. ANY string interpolation into code strings is equivalent to code injection. The PATTERN of string-building + code-evaluation is inherently dangerous regardless of the apparent trustworthiness of the data source. Fix: use safe property access (e.g., `obj[key]`, bracket notation, `array.reduce((o, k) => o[k], root)`, or a safe expression parser) instead of building code strings. + +**Arbitrary File Access from Client Parameters**: When a web application reads or writes files based on parameters received from HTTP requests, the path MUST be validated against a whitelist of allowed directories. Using `file_get_contents($parameters['viewFile'])` or similar with client-controlled paths enables arbitrary file read/write. Fix: validate with `realpath()`, restrict to specific directories, check file extensions, and reject paths containing `..`. + +**GitHub Actions Injection**: In GitHub Actions workflows, user-controlled values from `github.event.client_payload`, `github.event.issue.title`, `github.event.pull_request.title`, etc. must NEVER be interpolated directly into `run:` scripts or `ref:` parameters. An attacker controlling the PR title or client_payload can inject arbitrary commands. Fix: pass values via environment variables (`env:` block) or validate format (e.g., ensure `pr_number` matches `^[0-9]+$`). + +**Unfiltered Serialization / Nested Data Exposure**: When a model's serialization method (`to_dict`, `to_json`, `serialize`, `as_json`, `__dict__`, marshmallow/pydantic schemas) includes related/nested records (e.g., `collection.recipes`, `user.orders`, `project.tasks`), those nested records must be filtered based on the VIEWING user's permissions, not just the parent record's permissions. A public collection containing a private recipe must not expose the private recipe's details when serialized. This is an information disclosure vulnerability that lives in the model layer, not the route handler — check serialization methods, not just endpoints. + +**Data Flow to Pre-existing Dangerous Sinks**: If newly added code routes user-controlled data to a PRE-EXISTING dangerous sink (like `new Function()`, `eval()`, `exec()`, shell commands, or SQL concatenation), this is a NEW vulnerability even though the sink itself is unchanged. The attack surface expanded because the new code created a new path from untrusted input to the dangerous sink. Flag this as a new vulnerability in the + lines, citing both the new data flow and the pre-existing sink it reaches. + +**Reasoning guidance for authorization and business logic reviews**: +- For each endpoint, ask: "If user A makes this request with user B's resource ID, what stops them?" If the answer is "nothing," it's an IDOR. +- For list endpoints, ask: "Does the query filter by the current user's scope?" An unfiltered query in a multi-user system is an authorization bypass. +- For interaction endpoints (rate, review, comment, like), ask: "Does the code verify the user can access the parent resource before allowing the interaction?" +- For form submissions, ask: "Can a user submit a foreign key ID (e.g., customer_id, project_id) that belongs to another user?" +- For redirect endpoints, ask: "Is the redirect target validated to prevent open redirect to external sites?" + +**Completeness check**: When a resource has a visibility/privacy/ownership field, systematically enumerate EVERY endpoint that accepts that resource's ID (not just view endpoints — also create, update, delete, rate, comment, share, assign, and any interaction endpoints). For each one, verify it checks the visibility/ownership field. Do NOT stop after finding one issue — continue checking all endpoints for the same resource. Applications commonly secure the main view endpoint but forget interaction endpoints. If you find one endpoint correctly checking visibility, that does NOT mean all endpoints do — verify each one independently. + +**Do not skip syntactic patterns**: Unescaped template output, subprocess shell=True, innerHTML with user data, and similar textbook patterns still appear in real diffs and still need flagging here. Review both the obvious sinks AND the higher-level logic (authorization, data access, SSRF validation completeness, business rules). + +**Distrust safety claims**: Comments and docstrings that assert safety ("SSRF-safe", "validated upstream", "not user input", "sanitized above") are claims, not evidence. Verify the invariant holds in the visible code. A safety-named wrapper class guards one code path — check whether ALL paths to the dangerous operation go through it, or whether some bypass it. If you cannot verify the claim from the diff, treat the code as if the comment were absent. + +**Check for missing controls, not just added sinks**: A new handler, route, or auth path can be vulnerable because of what it LACKS, not what it adds. Compare it against sibling handlers in the same file: if they check membership/ownership/origin and this one doesn't, the omission is the vulnerability. For new download/file-serving endpoints, check whether Content-Disposition is set. For new WebSocket/connection handlers, check whether origin is validated. For new authz paths, check whether ALL verification steps from the established path are present. + +**Keep scanning after the first finding**: A file can have multiple independent issues. A lesser finding (verbose error, quota bypass, missing header) does not mean the critical one (IDOR, authz-before-mutation ordering, injection) is absent — they often coexist in the same function. Report all HIGH/CRITICAL findings, not just the first. + +IMPORTANT: Flag only vulnerabilities with a concrete attack path from untrusted input to dangerous sink. Most code is benign and should pass with no findings. False positives waste developer time; false negatives let vulnerabilities ship. Both matter. + +DECISION FRAMEWORK: +- You need a concrete attack scenario, but the attacker model can be any authenticated user, any network peer, or any untrusted data source — not just an external anonymous attacker +- If the code is a CLI tool, script, seed file, test, or internal utility — apply extra skepticism about web vulnerabilities + +DO NOT flag: +- Missing authentication on a service described as internal/VPN-only (but note: internal-only deployment does NOT excuse SSRF — internal services are the primary target of SSRF attacks, and cloud metadata endpoints must always be blocked regardless of stated deployment context) +- Missing HTTPS/TLS, missing rate limiting, or missing input length validation +- Denial of Service (DoS) concerns: missing timeouts, missing pagination limits, unbounded loops, resource exhaustion, memory consumption — these are best-practice improvements, not exploitable vulnerabilities +- Pre-existing issues that are completely unrelated to the current changes (if a diff is provided) +- Hardcoded configuration values that are NOT credentials: project IDs, dataset names, table names, service names, hostnames, port numbers, file paths, URLs to public APIs, resource identifiers. Only flag ACTUAL secrets: passwords, API keys/tokens, private keys, connection strings containing credentials +- Development fallback secrets like `os.environ.get('SECRET_KEY', 'dev-fallback')` or `process.env.SECRET || 'dev-default'` — these are legitimate development patterns +- Flask/Django SECRET_KEY or session secrets in development/example code, seed scripts, or test files — only flag in production config files +- Path traversal in code where the path is NOT user-controlled (e.g., file paths constructed from hardcoded strings, config values, CLI arguments in trusted tools, or internal function parameters). Environment variables and CLI arguments are trusted input sources. +- XSS in code that does not handle HTTP requests or render HTML to browsers (e.g., CLI tools, backend services, data processing scripts, seed files). React auto-escapes text content, BUT flag: `dangerouslySetInnerHTML` with user input; user-controlled `href`/`src`/`location` without an http(s) scheme allowlist (`javascript:`/`data:` URIs execute); second-stage template placeholders (`{{var}}` lacking `|e`) embedded as string literals in JSX/MJML/email builders — the outer auto-escape only preserves the braces. +- Open redirect in code that does not handle HTTP requests +- SSRF in code where URLs are not user-controlled (e.g., hardcoded API endpoints, config-driven URLs). SSRF where the attacker only controls the path (not host or protocol) is generally lower severity, BUT should still be flagged as a potential low severity issue. +- SQL injection in code using parameterized queries, ORMs, or query builders (these are safe by design) +- GitHub Actions injection where the only tainted value is `github.event.inputs.*` / `inputs.*` on a `workflow_dispatch`-triggered workflow (the dispatcher already has repo-write), or where the value lands in a `with:` input rather than a `run:` shell step. +- Race conditions or timing attacks that are theoretical rather than practically exploitable +- Log spoofing concerns +- Crashes from undefined variables, missing keys, or type errors — these are bugs, not security vulnerabilities +- Telemetry/analytics API keys (Honeycomb, Datadog, Sentry, etc.) — these are designed to be client-side +- Open redirect in URL shorteners, link redirectors, or proxy endpoints where redirecting to user-provided URLs IS the intended feature +- Vulnerabilities in pre-existing starter/template code that was not written by the developer in this session + +{files_text} + +Respond with a JSON object.

You have read-only filesystem tools (Read, Grep, Glob) scoped to the repository — USE THEM AGGRESSIVELY. The diff alone is not enough. + +The #1 cause of missed vulnerabilities is not reading the file that contains them. Before any analysis: Read EVERY changed file in full (not just the diff hunks). Then Grep for the changed function/class names to find callers. A vulnerability that requires cross-file context is still your responsibility. + +METHOD: + +Phase 1 — Map entry points and sinks touched by this change. + Entry points: HTTP handlers/routes, RPC methods, CLI args, webhook receivers, message consumers, file/upload handlers, OAuth callbacks, GitHub Actions inputs, MCP tools, hook handlers, IPC receivers (main/privileged process handling messages from a sandboxed/renderer/less-privileged process). + Sinks: shell/exec/subprocess, SQL/ORM raw, eval/new Function, filesystem paths (open/read/write/unlink), outbound HTTP (SSRF), HTML render/innerHTML, deserialization (pickle/yaml/json with object_hook), template engines, subprocess env, IAM/RBAC bindings, dynamic code/plugin/extension loaders (any API that loads+executes code from a path), log/telemetry/metrics dimensions (only when value matches a PII shape — email, token, free-text field; NOT a static enum/type name), cache-control / Vary headers (cache poisoning), DDL that drops a constraint/FK/trigger (referential-integrity), response bodies/headers, prompts sent to LLMs. + For each changed file, Grep for the function/class names in the diff to find their callers and what data reaches them. + +Phase 2 — Trace data flow. + For every value that reaches a sink, determine whether it is attacker-influenceable. Read upstream: where does the variable come from? Is there validation/sanitization between source and sink? Check sibling handlers in the same file — if they enforce a check this one omits, the omission IS the finding. Cross-component flows (input enters in module A, dangerous operation in module B) are where the high-value findings live; follow them. + FOLLOW RETURNS: when a changed function builds a tainted value (command string, SQL, URL, path, template) and RETURNS it rather than executing locally, the sink is in a CALLER — Grep for the function name and read the call sites before deciding it's safe. + SIBLING-PATH GATE PARITY: when + lines add a guard/check/tenant-scope/visibility-filter/invalidation/cleanup to ONE branch, ONE handler, or ONE layer, enumerate ALL sibling branches, early-returns, error/except paths, and peer handlers in the same router/service that touch the same resource — report any that lack an equivalent gate. ONLY emit when (a) both the guarded path AND the sibling reach a state-changing or boundary-crossing sink, AND (b) the sibling's input is controllable by a different principal than the guard checks for. Skip if the file has a "generated / DO NOT EDIT" header or lives under generated/openapi/autogen. + +Phase 2b — Parser/validator differentials (a top miss category). + When the change adds or modifies parsing, validation, normalization, or matching logic (regexes, URL/path parsers, allowlists, content-type checks, decoders, AST/shell parsers), ask: does an input exist that the validator ACCEPTS but the downstream consumer interprets differently? Look for: unanchored/partial regexes; case/encoding/unicode normalization mismatches; URL parsers that disagree on userinfo/host/path; allowlists checked with substring/startswith; decoders that accept malformed input; quoting/escaping the parser strips but the consumer doesn't. The finding is the differential itself — name both sides. + +Phase 2c — High-miss patterns. Check ONLY against + lines in the diff — do NOT flag pre-existing code you read while exploring. + - SENSITIVE-TO-OBSERVABILITY: a + line emits to a log/trace/span/metric/exception-message sink. Trace EVERY field (including URLs, paths, error-object .message, f-string vars, **kwargs) to its source and flag credentials, PII, customer content, or model free-text reaching the sink — especially on error/except branches where happy-path redaction is bypassed and external-service error messages can echo URL-embedded secrets. Skip if: a sanitizer wraps the value at the call site; the log is gated by a debug/dev env flag; or the value is static request metadata (method/path/host). + - IaC OMITTED ARG: a + line instantiates a Terraform/Pulumi/CDK module and OMITS an optional security-relevant arg — read the module's variables and check whether the default is the secure value. + - CI/CD TRUST: + lines add or change a GitHub Actions trigger to workflow_dispatch / repository_dispatch / pull_request_target without a branches: filter, AND the job reads secrets or has write permissions. + - ALLOWLIST SEMANTIC ESCAPE: + lines add an entry to a safe-command/safe-endpoint/capability allowlist OR add a `||` disjunct to a permission matcher OR edit a validator that gates exec/eval/subprocess. Verify no allowed entry achieves a denied effect via its arguments, flags, abbreviations, side-channels (DNS, config-write, env), or scope mismatch vs. enforcement (e.g., allowlist matches argv[0] but consumer reads full argv). + - OVER-BROAD GRANT: when + lines add a principal/identity to a broad-scope permission (global/service-wide allowlist, standing admin role binding, reuse of another principal's credential), check whether the SAME changed file or its immediate module already exposes a narrower-scope mechanism for the same need (per-resource/per-RPC allowlist, break-glass/2PC role, dedicated principal). If it does, the broad grant is the finding. Do NOT flag if no narrower mechanism is visible in the changed files. + - STALE IDENTITY MAPPING: + lines change teardown/unregister of an identity primitive (hostname/DNS, IP, service route, lease, auth token, service-registry entry) where a window leaves it resolvable to the wrong tenant. NOT in-process data caches. + - CONTROL REGRESSION: when - lines DELETE a fail-closed validator (allowlist returning False by default, _is_safe_*, deny-by-default) and + lines replace it with a single condition, the replacement IS the finding. + - FAIL-OPEN STATE DRIFT: when a security decision reads parsed/cached/tracked/callback state, verify error, cancellation, TOCTOU, cache-skew, and unhandled-variant paths do not yield a default that skips enforcement — broad-except→pass, unwrap_or({}), missing-finally cleanup, ignored verifier params, or stale validator maps all fail open. The finding is the path where the fallback value is the allow outcome. Also: when + lines compare against a security threshold, check whether the EXACT boundary value yields the permissive branch; when an error path triggers retry/redelivery, check whether the retry can emit a decision that overrides a stricter first decision; when sync logic reads persisted state, check whether state surviving a data wipe causes destructive sync. + - SECURITY-REGISTRY FANOUT: when + lines add a new entity (field, enum value, credential type, alias, model variant, port, scope), Grep unchanged files for every security registry keyed on that entity class — sanitizer field-lists, redaction sets, revocation handlers, strip denylists, capability allowlists, translation maps — and flag if the new entry is missing from any. Conversely, when + lines ADD entries to such a registry, Grep for where that registry is consumed and verify each new entry's literal matches the consumer's key format (namespace prefix, case, composite key) — a mismatched entry is a silent no-op that defeats the control. + - GATE/ACTION FIELD MISMATCH: when + lines add or modify an authorization/policy check, identify which request field(s) the gate reads vs which field(s) the downstream operation uses to select the target resource. If they differ (gate checks `parent`, action derives target from `name`; gate checks org A, action writes to org from a separate param), the gate is bypassable. + - RESOURCE-BOUND PLACEMENT: when + lines parse/decompress/fetch/loop over attacker-influenced input, verify size/time/count caps guard the ACTUAL peak allocation — not a post-flush output, post-decompress buffer, per-iteration (not total) timeout, unclamped arithmetic (subtraction underflow, multiplication overflow), or first-element-only invariant. The finding is the cap defeat, not the DoS itself. + - UNDER-VALIDATED SINK ARG: when + lines interpolate any externally-influenced value (incl. IPC, VCS-checkout content, env var, model output, domain-syntax strings) into a shell/path/loader/URI/structured-format sink, verify quoting, traversal/UNC/symlink stripping, and prod-mode guards apply to THIS arg — existing validators on sibling args do not cover it. + +Phase 3 — Assess. + Report when you can name (a) the source, (b) the sink, (c) the path with no effective mitigation. Medium-confidence is fine — a separate adjudication pass will filter; your job is RECALL, not precision. Do report logic/authorization bugs (missing ownership check, inverted condition, parser differential) even when no classic "sink" is involved. + +Do NOT report: missing best-practice/hardening with no concrete impact, test/mock files, outdated deps, or volumetric DoS (attacker just sends a lot). DO report DoS when the diff introduces a code defect that defeats an existing resource cap (cap on wrong accumulator, dead timeout handler, unclamped arithmetic, encoding amplification at flush) — those are logic errors with security impact. + +Distrust safety claims in comments ("validated upstream", "internal only"). Verify in code. + +Keep scanning after the first finding. Do NOT emit findings until you have Read EVERY touched file at least once — a more obvious pattern in file A does not excuse skipping file B. Aim for at least one candidate or explicit "no sink" verdict per touched file. + +Return an object with key `findings` — a list of {filePath, category, +vulnerableCode, explanation, fix, severity, confidence} records. severity +is "critical", "high", or "medium".

It runs as +UserPromptSubmit, PostToolUse, and Stop hooks via the Claude Code plugin system. + +## Architecture + +The plugin has two layers: + +1. **Pattern-based rules (PostToolUse, every edit)**: Fast regex checks that run on + every file write. Detects common vulnerabilities like hardcoded secrets, SQL injection, + command injection, path traversal, and insecure session configs. Injects brief warnings + via additionalContext. + +2. **Stop hook (final review)**: When Claude finishes, uses `git diff` against a + baseline SHA (captured at UserPromptSubmit) to get only the code changed during the + session. Runs two Haiku analyses on the diff: + a) Concrete vulnerability scan with severity ratings + b) Areas-of-concern analysis identifying categories to investigate + Exits with code 2 to force Claude to continue and address findings. + +## How the git baseline works + +On each UserPromptSubmit, the plugin runs `git stash create` to get a SHA representing +the current working tree state (HEAD + any uncommitted changes). This SHA is saved to +the session state file. When the Stop hook fires, it runs `git diff ` to +get only the changes made since that snapshot. After analysis, the baseline is updated +so the next Stop hook iteration only sees new changes. + +This means: +- Only code Claude actually changed is reviewed (not pre-existing code) +- Mid-session commits are handled correctly (diff is against the snapshot, not HEAD) +- Each turn only reviews new changes (baseline updates after each stop hook) + +## Configuration + +Kill switches: +- SECURITY_GUIDANCE_DISABLE: "1" to fully disable the plugin (alias for ENABLE_SECURITY_REMINDER=0) +- ENABLE_SECURITY_REMINDER: "0" to fully disable the plugin (legacy name) + +Per-feature toggles (all default enabled; set to "0" to disable): +- ENABLE_PATTERN_RULES: PostToolUse regex warnings on Edit/Write +- ENABLE_CODE_SECURITY_REVIEW: Stop-hook git-diff LLM review +- ENABLE_COMMIT_REVIEW: PostToolUse[Bash] commit security review + +Other: +- SECURITY_REVIEW_MODEL: Model for LLM review (default: claude-opus-4-7) +- ANTHROPIC_API_KEY: Required for LLM-based reviews +- ANTHROPIC_AUTH_TOKEN: Alternative to API key — OAuth access token sent as Bearer auth. + Claude Code passes this automatically for OAuth-authenticated users. +""" + +try: + import fcntl +except ImportError: + fcntl = None +import contextlib +import glob +import json +import os +import random +import re +import subprocess +import sys +import threading +import urllib.request +from datetime import datetime +from enum import IntEnum +from typing import Optional, Tuple, Dict, Any, List + +# review_api is the importable surface for the agentic-review prompts, +# schemas, and pure filters.
