Audit Trail Skill

Goal

Maintain a tamper-evident, chronological record of all significant decisions, changes, and outcomes for compliance, debugging, project continuity, and team transparency.

When to Auto-Log (triggered by other skills)

• Every SDLC phase transition (sdlc-checkpoint.skill)
• Every human decision (when human provides direction or approval)
• Every ADR creation (adr-writer.skill)
• Every failed self-heal attempt and resolution (self-heal.skill)
• Every security finding and its remediation (security-audit.skill)
• Every task DONE, BLOCKED, or FAILED
• Every quality gate pass/fail with scores
• Every research finding that changes implementation approach

Log Entry Format

Append to: agents/memory/AUDIT_LOG.md

Table format:

| [ISO datetime] | [Session-ID] | [Agent/Human] | [Action Type] | [Description] | [Outcome] | [References] |

Action Types:

DECISION         - A choice made between options
PHASE_TRANSITION - SDLC phase changed
TASK_DONE        - A task was completed successfully
TASK_BLOCKED     - A task is stuck, human decision needed
QUALITY_GATE     - Quality gate pass/fail result with scores
SECURITY_FINDING - Security issue found (severity + description)
ADR_CREATED      - Architecture decision documented
HUMAN_ESCALATION - Agent escalated to human (blocked after 5 attempts)
SELF_HEAL_ATTEMPT- Agent tried to fix itself (attempt N of 5)
RESEARCH_FINDING - Authoritative source verified (for future reference)
ERROR            - Unexpected error encountered
ROLLBACK         - Change was reverted
HUMAN_APPROVED   - Human provided approval for a phase or decision

Steps

1. Determine what needs to be logged

   • Was a decision made? (architecture, library choice, requirement interpretation)
   • Did a task complete or get blocked?
   • Did a quality gate run?
   • Did a human provide input or approval?

2. Write the log entry

   bashCopy

   # Get current timestamp
   date -u +"%Y-%m-%dT%H:%M:%SZ"
   

   Example entries:

   Copy

   | 2025-03-15T14:23:00Z | S01-001 | prod-pm | PHASE_TRANSITION | PRD.md approved by human | SUCCESS | docs/PRD.md |
   | 2025-03-15T14:25:00Z | S01-001 | human | HUMAN_APPROVED | Approved PRD.md — proceed to design | APPROVED | docs/PRD.md |
   | 2025-03-15T15:10:00Z | S02-001 | prod-architect | ADR_CREATED | Chose Prisma over TypeORM for ORM | ACCEPTED | docs/architecture/decisions/ADR-001-prisma.md |
   | 2025-03-15T16:00:00Z | S05-001 | eng-backend | TASK_DONE | Implemented CreateUserUseCase | SUCCESS | src/application/create-user.use-case.ts |
   | 2025-03-15T16:45:00Z | S05-001 | eng-backend | SELF_HEAL_ATTEMPT | Type error on UserDto.email field — attempt 1/5 | FAIL | src/application/create-user.use-case.ts:42 |
   | 2025-03-15T16:50:00Z | S05-001 | eng-backend | TASK_DONE | Fixed type error via research (strict null check) | SUCCESS | src/application/create-user.use-case.ts |
   | 2025-03-15T17:00:00Z | S05-001 | ops-security | SECURITY_FINDING | HIGH: Missing rate limit on /auth/login | OPEN | src/adapters/http/auth.controller.ts:23 |
   | 2025-03-15T17:30:00Z | S06-001 | orch-judge | QUALITY_GATE | Gate 3 Tests: 247 pass, 0 fail, 84% coverage | PASS | — |
   

3. APPEND ONLY — never modify existing entries

   • Use bash append operator: >> agents/memory/AUDIT_LOG.md
   • Never use a write that overwrites the file
   • If a decision is reversed: add a new ROLLBACK entry (don't delete the original)

4. Verify the append worked

   • Read the last few lines to confirm the entry was added correctly

Querying the Audit Log

For humans reviewing history:

# Find all security findings
grep "SECURITY_FINDING" agents/memory/AUDIT_LOG.md

# Find all human decisions
grep "HUMAN_APPROVED\|DECISION" agents/memory/AUDIT_LOG.md

# Find all escalations
grep "HUMAN_ESCALATION" agents/memory/AUDIT_LOG.md

# Find history for a specific file
grep "auth.controller.ts" agents/memory/AUDIT_LOG.md

Constraints

• APPEND ONLY — never delete or modify existing entries
• Every SDLC phase transition must be logged immediately
• Security findings must be logged even if they will be fixed immediately
• Human decisions must be logged with the actual decision made (not just "human approved")
• Log is shared across all agent sessions — it provides continuity

Output Format

New row appended to AUDIT_LOG.md. No output to user unless requested.
