Tamper-evident, hash-chained audit logging for AI agents. EU AI Act compliant.
Why
AI agents act on your behalf. From 2 August 2026, the EU AI Act requires automatic logging, tamper-evident records, and human oversight capability for AI systems. This skill provides all three with zero dependencies.
Quick Start
1. Add to your agent's workspace
cp scripts/auditlog.py /path/to/your/workspace/scripts/
chmod +x /path/to/your/workspace/scripts/auditlog.py
2. Log an action
./scripts/auditlog.py append \
--kind "file-write" \
--summary "Created config.yaml" \
--target "config.yaml" \
--domain "personal"
3. Verify integrity
./scripts/auditlog.py verify
# Output: OK (N entries verified)
Compliance Mapping
| EU AI Act Article | Requirement | How This Skill Helps |
|---|---|---|
| Art. 12 Record-Keeping | Automatic event logging | Every action logged with timestamp, actor, domain, target |
| Art. 12 Integrity | Tamper-evident records | SHA-256 hash chaining — modification breaks the chain |
| Art. 14 Human Oversight | Human approval linkage | --gate flag links actions to human approval references |
| Art. 50 Transparency | Auditable records | Human-readable NDJSON, one-command verification |
| Art. 12 Traceability | Chronological ordering | Monotonic ord tokens |
Event Kinds
Use these standardised event types for consistent audit trails:
| Kind | When to Use |
|---|---|
| file-write | Agent creates or modifies files |
| exec | Agent runs a command |
| api-call | External API interaction |
| decision | AI makes or recommends a decision |
| credential-access | Secrets or credentials accessed |
| external-write | Agent writes to external systems |
| human-override | Human overrides an AI decision |
| disclosure | AI identity disclosed to user |

OpenClaw Integration
Add to HEARTBEAT.md:
## Audit integrity check
- Run: `./scripts/auditlog.py verify`
- If fails: alert with line number + hash mismatch
- If OK: silent
Requirements
- Python 3.9+ (zero external dependencies)
