modbender Black Box (Powered by TiDB Zero)
Overview
Black Box is an indestructible audit log for AI Agents. It acts as a "Flight Data Recorder" that streams critical actions, errors, and reasoning chains to a persistent cloud database (TiDB Zero) in real-time.
Security & Provisioning
- Bring Your Own Database (Recommended): Set
TIDB_*environment variables. - Auto-Provisioning (Fallback): If no credentials are found, this skill uses the TiDB Zero API to create a temporary database for logging. The connection string is cached in
~/.openclaw_black_box_dsn.
Why use this?
- Crash Survival: Local logs vanish when containers crash. Cloud logs persist.
- Audit Trail: Prove exactly what your agent did and why (compliance).
- Debugging: Retrieve the last 100 actions leading up to a failure.
Prerequisites
- TiDB Credentials: Standard MySQL connection parameters (
TIDB_HOST,TIDB_USER, etc.). - Network: Outbound access to TiDB Cloud (port 4000).
Usage
1. Log an Event
Record a critical action or error:
python {baseDir}/run.py --action log --level ERROR --message "System crash imminent: Memory leak detected"
2. Read Logs
Retrieve the last N logs (default: 10):
python {baseDir}/run.py --action read --limit 20
Schema
This skill creates a table agent_logs with columns: timestamp, level, message, metadata (JSON).
