Hawthorn 8d360fb466 fix: address remaining review nits
- Add top-level hooks wrapper to second JSON example (consistent with hooks.json format)
- Extract hardcoded thresholds as module-level constants (WALL_OF_TEXT_WORDS,
  SUMMARY_CHECK_WORDS, SUMMARY_CHECK_FIRST_N, TASK_OUTPUT_RATIO_HIGH/MEDIUM)

Skipped (not applicable):
- 'Scoring defaults to 5/5' — by design for heuristic fallback; SKILL.md already
  documents pairing with LLM judge for production use
- '--output silently ignored' — already fixed by _read_input refactor (checks
  args.output directly, not elif args.task and args.output)

Hook Integration for Session-Stop Self-Evaluation

Add this hook to hooks/hooks.json to remind the agent to self-evaluate at the end of every session (the hook echoes a reminder; it does not run the evaluator automatically):

{
  "hooks": {
    "Stop": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "echo '[Self-Eval] Session complete. Consider running agent-self-evaluation to rate your output.'"
          }
        ],
        "description": "Remind agent to self-evaluate at session end"
      }
    ]
  }
}

Stop events do not require a matcher field (it is optional for Stop, Notification, UserPromptSubmit, and SubagentStop per scripts/ci/validate-hooks.js). If omitted, the hook object only needs hooks and metadata such as description.

Integration with the Python Evaluator

The scripts/evaluate.py script can be used as a standalone tool:

# Pipe agent output directly
echo "Your agent response here" | python3 skills/agent-self-evaluation/scripts/evaluate.py

# From files
python3 skills/agent-self-evaluation/scripts/evaluate.py --task task.txt --output response.txt

To integrate it into hooks, capture the last agent output to a file first, then run the evaluator. For lightweight reminders after shell-based verification, use a simple supported matcher string:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Bash",
        "hooks": [
          {
            "type": "command",
            "command": "echo '[Self-Eval] If this command completed verification for a non-trivial task, consider running agent-self-evaluation.'"
          }
        ],
        "description": "Remind agent to self-evaluate after shell verification"
      }
    ]
  }
}

This avoids documenting unsupported command-expression matcher syntax. If your harness supports command-level matcher expressions, prefer a word-boundary regex such as \b(pytest|npm test|go test)\b rather than a broad test substring.

These hooks are opt-in. Add them to your local hooks/hooks.json if you want automated evaluation prompts.

The most reliable approach is manual invocation — the agent runs self-evaluation as part of its workflow when the agent-self-evaluation skill is active, without requiring hook configuration. The skill's "When to Activate" section already covers trigger conditions (multi-file changes, debugging sessions, design documents).
