| agent-harness v1 — FORGE Safety Wrapper + Injection Prevention | |
| ============================================================== | |
| Middleware layer sitting between agents and the outside world. | |
| Every tool input is scanned before execution. | |
| Every tool result is sanitised before the LLM sees it. | |
| Suspicious agents get circuit-broken and christof gets alerted. | |
| Features | |
| -------- | |
| POST /api/scan/input Scan tool args before execution (injection + policy) | |
| POST /api/scan/output Sanitise tool result before feeding back to LLM | |
| POST /api/validate Check action against FORGE policy (rate limits, allowlist) | |
| GET /api/flags Recent flagged events with full payloads | |
| GET /api/circuit/{agent} Circuit breaker state for an agent | |
| POST /api/circuit/{agent}/reset Reset after operator review | |
| GET /api/stats Aggregated safety stats | |
| GET /api/rates Current rate limit counters per agent/tool | |
| GET /api/health Health check | |
| GET /mcp/sse POST /mcp MCP server | |
| Safety layers | |
| ------------- | |
| Layer 1 — Pattern scanner : regex patterns for all known injection attack formats | |
| Layer 2 — Token scanner : LLM token injection for qwen / mistral / llama / phi | |
| Layer 3 — Bash danger check : destructive shell commands in vault_exec payloads | |
| Layer 4 — Tool policy : each agent has an allowed tool list (from FORGE) | |
| Layer 5 — Rate limiter : per-agent per-tool N calls / 60s window | |
| Layer 6 — Circuit breaker : 3 flags in 60s → pause agent → alert christof | |
| Layer 7 — Output sanitiser : strip injected instructions from tool results | |
