Audit

Live Context

Current audit context:

• Recent git commits: !git log --oneline -10 2>/dev/null || echo "No git history"
• Git authors today: !git log --since="midnight" --format="%an" 2>/dev/null | sort | uniq -c || echo "None"
• Uncommitted changes: !git status --short 2>/dev/null || echo "Not a git repo"
• Recent file modifications: !find . -type f -mtime -1 -not -path './.git/*' 2>/dev/null | wc -l | tr -d ' ' files in last 24h
• Audit log exists: !ls -la .audit/ 2>/dev/null | head -5 || echo "No .audit/ directory"
• Checkpoint log exists: !ls -la .checkpoints/ 2>/dev/null | head -5 || echo "No .checkpoints/ directory"

Intent

Execute audit to create a structured record of actions taken, tools invoked, changes made, and the reasoning behind decisions. This provides accountability, enables investigation of issues, and supports compliance requirements.

Success criteria:

• Complete chronological record of relevant actions
• Every action linked to actor, timestamp, and rationale
• Changes documented with before/after state
• Provenance chain for all outputs

Compatible schemas:

• schemas/output_schema.yaml

Inputs

Procedure

1. Define audit scope: Determine what to include in the audit

   • Parse scope parameter to identify targets
   • Apply time_window filter if provided
   • Identify relevant log sources (git log, tool invocations, file changes)

2. Collect action records: Gather all actions within scope

   • Read git log for commits and their messages
   • Review tool invocation history if available
   • Identify file changes (created, modified, deleted)
   • Record timestamps for each action

3. Extract decision rationale: Document the "why" for each action

   • Link actions to plans or goals that motivated them
   • Capture assumptions stated before action
   • Record any constraints that influenced decisions

4. Build provenance chain: Track inputs to outputs

   • For each output, identify its source inputs
   • Document transformations applied
   • List dependencies between artifacts

5. Ground claims: Attach evidence for all audit entries

   • Format: file:line, tool:git:commit_hash, timestamp
   • Include actual command outputs where relevant

6. Format output: Structure per audit contract

Output Contract

    commands: ["pytest tests/", "git diff", "git commit"]
decision_rationale: "Refactored to prevent SQL injection vulnerability identified in security audit. Added parameterized queries and corresponding test coverage."
provenance:
  inputs:

Verification

Apply the following verification patterns:

• Evidence Grounding: All changes linked to evidence_anchors
• Contract Validation: Output matches audit_record schema
• Completeness Check: No gaps in timeline for specified time_window
• Provenance Valid: All inputs and outputs are verifiable

Verification tools: Read (for log files), Grep (for searching history)

Safety Constraints

• mutation: false (audit is read-only observation)
• requires_checkpoint: false
• requires_approval: false
• risk: medium

Capability-specific rules:

• Never modify audited artifacts during audit
• Preserve original timestamps (do not alter history)
• Include failed actions, not just successes
• Redact sensitive information (credentials, PII) from audit output
• Store audit records in append-only manner when persisting

Composition Patterns

Commonly follows:

• verify - After verify PASS, audit the successful changes (CAVR pattern)
• act-plan - Audit what was executed
• rollback - Audit the rollback event itself

Commonly precedes:

• summarize - Summarize audit for stakeholder reporting
• persist - Store audit record for compliance

Anti-patterns:

• Never skip audit after act-plan (breaks accountability)
• Never modify artifacts during audit (breaks integrity)
• Never omit failed actions from audit trail
