ClawBigBrother

Production-grade MVP for an AI supervisor system that monitors and can block risky actions performed by an external agent (e.g. OpenClaw). ClawBigBrother runs as an independent long-running service and relies on side-channel signals (webhooks, proxy logs, filesystem watcher, optional social gateway) that you control. It does not wrap or modify the OpenClaw agent code.

Goals

  1. Observe — Ingest events from multiple collectors into a unified event schema.
  2. Decide — Evaluate each event with a policy engine (rules-first, optional LLM judge stub).
  3. Intervene — Produce enforcement actions (ALLOW / DENY / HOLD / RATE_LIMIT) and support blocking via an egress proxy decision endpoint and a manual review queue.
  4. Audit — Persist all events, decisions, and evidence hashes into Postgres.
  5. Report — Generate a daily security report summary and expose APIs + minimal UI.
  6. Run forever — Docker Compose–based local deployment with healthchecks, retries, and a worker service.

Tech Stack

  • Language: Python 3.11+
  • Web: FastAPI
  • DB: Postgres (Docker)
  • Event bus: Redis Streams (Docker)
  • Workers: asyncio (event consumer, filesystem watcher, daily report)
  • Config: Pydantic settings + YAML policy file
  • Logging: structlog JSON logs
  • Packaging: Poetry

Quick Start

Prerequisites

  • Docker and Docker Compose
  • Poetry (or pip install -e .)

Run with Docker Compose

# Start Postgres + Redis, run migrations, then API + worker
make up

# Or step by step:
docker-compose up -d postgres redis
sleep 5
make migrate
docker-compose up -d clawbigbrother clawbigbrother-worker
  • API: http://localhost:8000
  • Docs: http://localhost:8000/docs
  • Dashboard: http://localhost:8000/ui
  • Review queue: http://localhost:8000/ui/review

Run locally (no Docker for app)

# Start only Postgres + Redis
docker-compose up -d postgres redis
export CLAWBB_DATABASE_URL=postgresql+asyncpg://clawbb:clawbb@localhost:5432/clawbb
export CLAWBB_REDIS_URL=redis://localhost:6379/0
make migrate
poetry run uvicorn clawbigbrother.main:app --reload --host 0.0.0.0

# In another terminal: run the event consumer (processes events from Redis)
poetry run python -m clawbigbrother.workers.event_consumer

Example requests

See examples/ for curl scripts. Quick sanity check:

curl -s http://localhost:8000/health | jq .
curl -s "http://localhost:8000/gate/decision?actor_id=agent-1&url=https://api.safe.com&method=GET" | jq .
bash examples/run_examples.sh

Architecture

Event schema

  • Unified event (Pydantic):
    event_id, ts, source, actor{agent_id, run_id, user}, action{type, verb, target, params}, context{trace_id, parent_event_id, risk_hints, content_hash, content_preview}

  • Decision:
    decision_id, event_id, ts, outcome (ALLOW/DENY/HOLD/RATE_LIMIT), policy_hits, risk_score (0–100), rationale, enforcement{type, details}

Collectors (MVP)

| Collector | Endpoint / mechanism | Maps into unified schema | |------------------------|-----------------------------|---------------------------| | OpenClaw webhook | POST /ingest/openclaw | Best-effort mapping | | Proxy log | POST /ingest/proxy | URL, method, domain, etc.| | Filesystem watcher | Watchdog on ./workspace | FILE_WRITE + content_hash| | Social posting gateway | POST /social/post | Policy check; ALLOW=mock, HOLD=review queue |

Event bus

  • Events are published to Redis Streams (clawbb.events).
  • A worker consumes via consumer group, runs the policy engine, persists event + decision to Postgres, and adds HOLD items to the review queue.

Policy engine

  • Config: config/policies.yaml (domain allow/block lists, action type blocklist, keyword blocklist, risk threshold).
  • Rules:
    • Domain blocklist → DENY for WEB_REQUEST/PROXY.
    • Action type blocklist (e.g. COMMAND_EXEC) → DENY.
    • Keyword blocklist on content_preview → HOLD or DENY.
    • Rate limit per actor per action type (in-memory for MVP).
  • Outcome: DENY if any hard-block rule; HOLD if risk_score ≥ threshold or keyword hit; else ALLOW.
  • LLM judge: Stub interface with no-op implementation; extension point for future use.

Intervention

  • Egress proxy decision: GET /gate/decision?actor_id=...&url=...&method=... → {outcome, reason, request_id}. Lightweight Level-1 policy check (no DB for MVP).
  • Review queue: GET /review/items, POST /review/{id}/approve, POST /review/{id}/reject. Approve marks item and allows re-processing.

Persistence

  • Postgres (SQLAlchemy + Alembic): events, decisions, review_items, policy_versions, daily_reports.
  • Sensitive data: store hashes and redacted previews; avoid storing full sensitive plaintext by default.

Reporting

  • Daily report job: Aggregates last 24h (counts by outcome, top blocked domains, top policy hits, top actors); stores one row in daily_reports.
  • API: GET /reports/latest returns the latest report.

Minimal UI

  • Dashboard: /ui — Totals + last 50 events.
  • Review queue: /ui/review — Pending items with Approve/Reject (POST forms).

Threat model and safety

ClawBigBrother is designed to supervise an agent you already control (e.g. OpenClaw) using side-channel signals you own. The following principles apply:

Data minimization

  • Ingest only what is needed for policy and audit (URLs, domains, action types, content hashes, short previews).
  • Store content_hash and content_preview (length-limited) instead of full body when possible.
  • Avoid logging or persisting secrets, tokens, or PII in plaintext.

Auditability

  • Every ingested event and every decision is persisted (events + decisions tables).
  • Policy versions are hashed and stored (policy_versions) so you can reproduce why a decision was made.
  • Structured JSON logs (structlog) support trace_id and event_id for correlation.

Least privilege

  • The service does not execute agent code; it only observes and decides on events.
  • DB and Redis credentials are configurable and should be restricted in production.
  • Review queue actions (approve/reject) are explicit and logged.

Safe defaults

  • Deny by default for high-risk action types (e.g. COMMAND_EXEC denied unless policy explicitly allows).
  • Blocklist-first for domains; allowlist is optional and configurable.
  • HOLD for suspicious content (e.g. keyword hits) so a human can review before allowing.

Non-goals

  • No stealth. The system is an explicit supervisor, not hidden monitoring.
  • No spying on accounts you don’t control. Assume you have authorization to monitor the agent and the side-channel sources (webhooks, proxy, workspace, social gateway).
  • No storage of sensitive plaintext by default. Prefer hashes and redacted previews.
