A malware sample can embed adversarial text in its own strings output. A rogue process can write to a log file that the agent will read. A compromised binary can report false metadata. The model has no way to distinguish between legitimate tool output and poisoned tool output — unless something runs **before** the LLM sees anything. That's the problem AGENTSCOPE solves. ### The Second Problem: No Chain of Custody When a human investigator writes a forensic report, every finding is backed by a tool command, a timestamp, and a hash of the evidence artifact. Courts accept this. When an AI agent writes a forensic report, you have: - A text file - No record of which tools ran - No proof the output wasn't hallucinated - No way to verify if the chain of analysis was interrupted AGENTSCOPE solves this too. Every tool call, every finding, every block event is sealed to a WORM (Write-Once-Read-Many) chain. The chain is tamper-evident. Every finding links by sequence number to the exact tool call that produced it. Run `verify_chain` — it holds or it tells you exactly where it broke. --- ## What SnapKitty Sovereign OS Solves (The Bigger Picture) ``` ┌──────────────────────────────────────────────────────────────────┐ │ THE TRUST PROBLEM IN AI │ │ │ │ Current AI systems: │ │ • Make decisions you cannot verify │ │ • Produce outputs with no chain of custody │ │ • Can be manipulated through their inputs │ │ • Have no cryptographic proof of what they decided │ │ • Forget everything between sessions │ │ │ │ SnapKitty Sovereign OS: │ │ • Every decision signed Ed25519 before it leaves the agent │ │ • Every seal anchored to SHA-256 WORM chain — immutable │ │ • Every input filtered through BOB before the LLM sees it │ │ • 31 agents, each owns exactly one domain, cannot cross │ │ • WORM world dumps — the OS remembers across restarts │ │ │ │ Don't trust the agent.

BOB and SENTINEL execute before the LLM. The FSM enforces phase order in TypeScript code. The WORM chain is append-only at the filesystem level. None of these can be bypassed by telling the model to ignore them, because none of them are inside the model. --- ## Quickstart (on SIFT Workstation) ```bash # ── Step 1: Boot SIFT Workstation VM ────────────────────────────────────────── # Download OVA from: https://www.sans.org/tools/sift-workstation/ # Import into VirtualBox or VMware. Boot. Login. # ── Step 2: Install Protocol SIFT ───────────────────────────────────────────── curl -fsSL https://raw.githubusercontent.com/teamdfir/protocol-sift/main/install.sh | bash # ── Step 3: Clone AGENTSCOPE-SIFT ───────────────────────────────────────────── git clone https://github.com/SNAPKITTYWEST/agentscope-sift cd agentscope-sift npm install # ── Step 4: Run the demo (no evidence files needed — simulated data) ─────────── npm run build && npm run demo # ── Step 5: Inspect the sealed evidence chain ────────────────────────────────── cat cases/worm-chain.jsonl | python3 -m json.tool # ── Step 6: Verify chain integrity ──────────────────────────────────────────── node dist/verify_chain.js cases/worm-chain.jsonl # Output: CHAIN VERIFIED — 14 entries, 0 tampered, genesis matches ``` --- ## Wire into Protocol SIFT (MCP Config) ```json { "mcpServers": { "agentscope-sift": { "command": "node", "args": ["/path/to/agentscope-sift/dist/server.js"] } } } ``` The agent now has 14 typed forensic tools with BOB + SENTINEL running on every output. It physically cannot run `rm`, `dd`, `chmod`, or any destructive command — those bindings do not exist in the MCP server. --- ## Evidence Chain Entry Format Every entry in `cases/worm-chain.jsonl`: ```json { "seq": 4, "ts": "2026-06-15T14:23:11.042Z", "type": "FINDING", "tool": "list_processes", "phase": "act", "bob_verdict": "APPROVED", "sentinel_verdict": "APPROVED", "sentinel_trust_score": 0.89, "payload": { "finding": "suspicious_process_hierarchy", "detail": "svchost.exe (PID 1337) spawned cmd.exe — anomalous parent-child", "confidence": "confirmed", "tool_call_seq": 1 }, "prev_seal": "a3f9b2c4d1e8f7a3b2c4d1e8f7a3b2c4", "seal": "7c4d1e9f2a3b5c6d7e8f9a0b1c2d3e4f" } ``` `seal` = `HMAC-SHA256(JSON.stringify(entry_without_seal), secret)` `prev_seal` links every entry to its predecessor — break one, the whole chain fails verification. --- ## What Each Component Solves | Component | Problem it solves | |---|---| | **BOB Plasma Filter** | Malware can embed adversarial text in its own forensic output. BOB runs before the LLM sees anything. | | **SENTINEL Zero-Trust Gate** | Even clean output can have low trust scores. SENTINEL scores every result and the verdict travels with the finding. | | **5-Phase FSM** | AI agents skip reasoning steps when given ambiguous evidence. The FSM makes phase order a hard constraint in code. | | **Typed MCP Tools** | Raw shell access lets the agent run destructive commands or get confused by unconstrained output. Typed wrappers remove that surface. | | **WORM Chain** | There's no chain of custody for AI forensic findings. Every finding is sealed to its source tool call. `verify_chain` proves integrity. | | **Findings as confirmed / inferred / unresolved** | AI reports present all findings with equal confidence. AGENTSCOPE forces epistemic honesty at the schema level. | --- ## Judging Criteria Coverage | Criterion | How AGENTSCOPE addresses it | |---|---| | **Autonomous Execution Quality** | 5-phase FSM, self-correction on BLOCKED findings, `max_iterations` cap prevents runaway loops | | **IR Accuracy** | Typed tool wrappers prevent hallucination; findings labeled confirmed / inferred / unresolved; trust scores on every result | | **Constraint Implementation** | BOB + SENTINEL are architectural, not prompt-based. Tested against simulated adversarial payloads embedded in tool output. | | **Audit Trail Quality** | Every finding sealed to exact tool call by seq#. `verify_chain` proves full chain integrity. Format is court-exportable. | | **Breadth and Depth** | Memory forensics, disk analysis, timeline, malware scanning, network capture, file metadata, registry, prefetch, autoruns | | **Usability** | `npm install && npm run demo` inside SIFT VM. No config files, no API keys, no external dependencies for demo mode. | --- ## Built On ``` SnapKitty Sovereign OS collectivekitty.com ├── BOB Runtime Sovereign Alien Trust Demigod │ └── Plasma Filter Non-recursive adversarial pattern matching ├── SENTINEL Agent Zero-trust security, risk governance │ └── Zero-Trust Gate Trust scoring + injection signal detection ├── SealForge HMAC-SHA256 WORM chain │ └── append-only ledger Tamper-evident, exportable, verifiable ├── 5-Phase IR FSM perceive→reason→plan→act→observe └── OpenKitty MCP Server 14 typed SIFT tool wrappers Protocol SIFT teamdfir / SANS SIFT Workstation └── 200+ forensic tools volatility3, sleuthkit, yara, tshark, log2timeline ``` **Stack:** TypeScript · Node.js 18+ · MCP SDK · SANS SIFT Workstation --- ## 💬 Talk to SENTINEL About This Repo SENTINEL is the zero-trust security agent that designed the trust boundaries in this system.
