How do I protect my AI agent from prompt injection attacks where malicious content in the environment tries to hijack the agent? | ## Agent Security: Defending Against Prompt Injection
### The Threat Model
Prompt injection is unique to agents because agents process untrusted content (web pages, emails, files) as part of their operation. A malicious document can contain instructions like:
```

What are the best patterns for designing LLM tools/functions? I want to avoid common mistakes that make agents fail. | ## LLM Tool Design: Patterns and Anti-Patterns
### Core Principle: Tools Should Be Idempotent and Atomic
A well-designed tool is:
- **Atomic**: does one thing well
- **Idempotent**: safe to call twice (for retries)
- **Deterministic**: same input → same output (or clear about non-determinism)
- **Bounded**: returns a... |
How do I evaluate and test an AI agent system in production? What metrics matter and how do I catch regressions? | ## Evaluating AI Agents in Production
### The Challenge
Agents are harder to evaluate than single-turn LLMs because:
- Success depends on a multi-step trajectory, not a single output
- Tool calls can fail in ways that cascade
- Good reasoning can reach wrong answers; bad reasoning can reach right ones

How do I build a production-grade AI coding assistant that can read, understand, and modify codebases? Not just autocomplete — actual project-level reasoning. | ## Production AI Coding Assistant: Project-Level Reasoning

1. **Codebase indexing** — vector search over code

Explain the ReAct (Reasoning + Acting) pattern for LLM agents and show me how to implement it from scratch in Python. | ## ReAct Pattern: Reasoning + Acting for LLM Agents
ReAct interleaves **thought** (reasoning about what to do next) with **action** (using a tool) and **observation** (processing the tool result). This loop continues until the agent has enough information to answer.

How do I build an agent that can handle long-running tasks that might take hours, survive interruptions, and resume from where it stopped? | ## Resumable Long-Running Agent Tasks
### The Problem with In-Memory State

- Context windows fill up with intermediate steps
- Hard to inspect/debug intermediate state
- No ability to pause and resume

How should an AI agent handle complex multi-step tasks that require planning ahead? Show me planning patterns beyond simple ReAct. | ## Advanced Agent Planning Patterns
### Why Simple ReAct Falls Short
ReAct works step-by-step without looking ahead. For complex tasks (writing a research report, building a software feature), this leads to:
- Redundant work (researching the same topic twice)
- Wrong order of operations
- Missing dependencies between... |
My AI agent is doing unexpected things in production. How do I add observability to understand exactly what it's thinking and doing? | ## Agent Observability: Understanding What's Happening
### The Core Observability Stack
```
Agent Execution
↓
Span/Trace Layer (track every step)
↓
Structured Logs (machine-readable)

Metrics (aggregated signals)

Alerts (anomaly detection)

Explain the ReAct (Reasoning + Acting) pattern for LLM agents and show me how to implement it from scratch in Python. | ## ReAct Pattern: Reasoning + Acting for LLM Agents
ReAct interleaves **thought** (reasoning about what to do next) with **action** (using a tool) and **observation** (processing the tool result). This loop continues until the agent has enough information to answer.
### The Pattern Structure

How do I build a production-grade AI coding assistant that can read, understand, and modify codebases? Not just autocomplete — actual project-level reasoning. | ## Production AI Coding Assistant: Project-Level Reasoning
### Architecture for Codebase-Aware AI
A coding assistant that reasons at the project level needs:
1. **Codebase indexing** — vector search over code
2. **Symbol navigation** — find where things are defined/used
3. **Context assembly** — build relevant contex... |

My agent is slow because it calls tools one at a time. How do I run multiple tool calls in parallel? | ## Parallel Tool Execution in Agents
Claude natively supports parallel tool calls in a single response — when it identifies multiple independent tools to call, it returns them all at once. You just need to handle them in parallel on your side.

How do I evaluate and test an AI agent system in production? What metrics matter and how do I catch regressions? | ## Evaluating AI Agents in Production
### The Challenge
Agents are harder to evaluate than single-turn LLMs because:
- Success depends on a multi-step trajectory, not a single output
- Tool calls can fail in ways that cascade
- Good reasoning can reach wrong answers; bad reasoning can reach right ones
- The state spa... |

How do I build an agent that can handle long-running tasks that might take hours, survive interruptions, and resume from where it stopped? | ## Resumable Long-Running Agent Tasks
### The Problem with In-Memory State
For tasks that take hours:
- Process restarts lose all progress
- Context windows fill up with intermediate steps
- Hard to inspect/debug intermediate state
- No ability to pause and resume
### Solution: Persistent Task Checkpointing

What are the best patterns for designing LLM tools/functions? I want to avoid common mistakes that make agents fail. | ## LLM Tool Design: Patterns and Anti-Patterns
### Core Principle: Tools Should Be Idempotent and Atomic
A well-designed tool is:
- **Atomic**: does one thing well
- **Idempotent**: safe to call twice (for retries)
- **Deterministic**: same input → same output (or clear about non-determinism)
- **Bounded**: returns a... |
How do I protect my AI agent from prompt injection attacks where malicious content in the environment tries to hijack the agent? | ## Agent Security: Defending Against Prompt Injection
### The Threat Model
Prompt injection is unique to agents because agents process untrusted content (web pages, emails, files) as part of their operation. A malicious document can contain instructions like:
