agent-zero

name: agent-zero description: Debug and troubleshoot Agent Zero — ettametta's autonomous production loop. Use when the loop stalls, state recovery fails, renders crash, or the scouting/screening/brainstorming pipeline breaks.

Agent Zero Debugging

Agent Zero is ettametta's autonomous viral content loop: scout trends, screen for virality, brainstorm scripts, render video, publish — then sleep 4h and repeat.

Quick Diagnostics

# Agent status
curl -H "Authorization: Bearer $TOKEN" http://localhost:8000/api/v1/zero/status

# State in DB
docker compose exec -T db psql -U ettametta -d ettametta -c "SELECT id, is_running, current_step, last_run_at, next_run_at FROM agent_zero_states ORDER BY id DESC LIMIT 5;"

# Latest insights
curl -H "Authorization: Bearer $TOKEN" http://localhost:8000/api/v1/zero/insights

# KPI file (in-container)
docker compose exec api cat /tmp/agent_zero_kpis.json 2>/dev/null || echo "No KPIs yet"

Architecture

State Machine

IDLE → SCOUTING → SCREENING → BRAINSTORMING → RENDERING → PUBLISHING → WAITING (4h sleep)
  ↑                                                       |
  └───────────────────────────────────────────────────────┘
  On exception: ERROR → 5min backoff → retry from last state

Tools (8 registered)

Self-Healing

• State persistence: _persist_state() writes JSON to agent_zero_state DB table (columns: is_running, last_run_at, next_run_at, current_step)
• Startup recovery: load_and_resume() in src/api/main.py:195 reads DB and auto-restarts the loop if is_running was true
• Error backoff: Exception → current_step = "ERROR" → 300s sleep → retry

Common Issues

Loop stuck at ERROR

Agent caught an exception and is in 5-min backoff. Check logs:

docker compose logs --tail=100 api 2>&1 | grep -i "agent_zero\|AgentZero\|ERROR"

If persistent, check which step failed via GET /zero/status.

State not recovering after restart

load_and_resume() only fires if is_running=true in DB. Check:

docker compose exec -T db psql -U ettametta -d ettametta -c "SELECT is_running, current_step FROM agent_zero_states ORDER BY id DESC LIMIT 1;"

Remotion render fails in Agent Zero

Two render paths exist: HTTP API (tools/render.py) and direct CLI (tools/remotion_render.py). The CLI path uses subprocess.run — check if npx is available in the container:

docker compose exec api which npx

KPIs not updating

KPIs are written to /tmp/agent_zero_kpis.json. Container restarts wipe /tmp. This is by design (ephemeral metrics).

Screener returns empty

market_screener.py calls Groq LLM. Check:

docker compose exec api python3 -c "from src.api.config import settings; print('GROQ:', 'SET' if settings.GROQ_API_KEY else 'MISSING')"

Integration with OpenClaw

src/services/openclaw/skills/agent_zero.py exposes AgentZeroSkill — start/stop/status via chat commands. OpenClaw acts as the conversational frontend for Agent Zero.

Debugging Checklist

1. Is Agent Zero running? GET /zero/status
2. What step is it on? current_step field
3. DB state: SELECT * FROM agent_zero_states
4. Logs: docker compose logs api | grep -i agent_zero
5. LLM keys set? Check GROQ_API_KEY, OPENAI_API_KEY
6. Remotion available? npx remotion --version in container
7. Discovery service up? curl http://localhost:8000/api/v1/discovery/search
