Our review

This skill logs proof of completed work to a session log file for audit trail.

Strengths

Creates a persistent audit trail
Easy to implement with provided templates
Integrates with step execution workflow
Provides clear evidence for self-assessment

Limitations

Manual process relies on developer discipline
No automatic detection of actions
Logging to file may have privacy implications in shared environments

When to use it

After completing significant actions or steps in a plan to maintain an audit trail.

When not to use it

For trivial actions that don't need recording, or in environments where file-based logging is not appropriate.

Examples

Log step completion

Log the completion of step 3: Add user authentication with JWT. Files modified: src/auth.py, tests/test_auth.py. Outcome: success.

Log file change

Log a file change: edited src/utils.py to fix parsing bug. Reason: the parser was failing on empty input.

Log test run

Log test run: command 'pytest tests/' passed all 42 tests with 0 failures.

name: edge-log description: Log proof of completed work to the session log. Use after completing significant actions to maintain an audit trail.

Log Proof

Since Codex CLI doesn't have automatic PostToolUse hooks, this skill manually logs proof of completed work.

When to Use

Call this skill after:

Completing a step in the plan
Making significant file changes
Running tests
Any action that should be recorded for audit

Instructions

1. Gather Proof Information

Collect:

What was done: Brief description of the action
Files modified: List of changed files
Outcome: Success/failure and any relevant output
Timestamp: Current time

2. Append to Session Log

Add an entry to .proof/session_log.jsonl:

{
  "timestamp": "2025-01-15T14:30:00Z",
  "type": "manual_log",
  "action": "Completed step 3: Add user authentication",
  "files": ["src/auth.py", "tests/test_auth.py"],
  "outcome": "success",
  "details": "Added JWT-based auth, all tests pass"
}

3. Create Log Directory if Needed

If .proof/ doesn't exist:

mkdir -p .proof

4. Append Entry

echo '{"timestamp":"...","type":"manual_log",...}' >> .proof/session_log.jsonl

Log Entry Format

{
  "timestamp": "<ISO 8601 timestamp>",
  "type": "manual_log",
  "action": "<what was done>",
  "files": ["<list>", "<of>", "<files>"],
  "outcome": "success | failure | partial",
  "details": "<additional context>",
  "step": <step number if applicable>
}

Quick Log Template

For common actions, use these templates:

Step Completion

{
  "timestamp": "<now>",
  "type": "step_complete",
  "step": <N>,
  "description": "<step description>",
  "proof": "<evidence of completion>"
}

File Change

{
  "timestamp": "<now>",
  "type": "file_change",
  "files": ["<path1>", "<path2>"],
  "action": "create | edit | delete",
  "reason": "<why this change was made>"
}

Test Run

{
  "timestamp": "<now>",
  "type": "test_run",
  "command": "<test command>",
  "result": "pass | fail",
  "details": "<N tests, M failures>"
}

Integration with Other Skills

The $edge-step skill should call $edge-log after completing each step.

Example workflow:

$edge-step executes the work
Work completes successfully
$edge-log records the proof
active_context.yaml is updated with step completion

Why This Matters

Without automatic logging:

There's no audit trail of what happened
Proof claims are unverifiable
State changes are invisible

Manual logging provides:

Accountability
Debugging history
Evidence for self-assessment
