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

1. Bring Your Own Database (Recommended): Set TIDB_* environment variables.
2. 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).
