$ARGUMENTS のカバレッジテンプレートを作成して境界値分析・テスト追加を実施しよう。

以下を TODO リストに追加：

  1. 記憶の再確認（~/config/claude/CLAUDE.md, ./**/CLAUDE.md, /mcp__memory__read_graph）
  2. uv run python ./scripts/coverage_checker.py FILENAME を使ってカバレッジを確認
  3. カバレッジチェックリストが存在しない場合 uv run python ./scripts/coverage_checker.py FILENAME --generate-templates を使って生成
  4. チェックリストがなかった関数について境界値分析を実施
  5. テンプレートに従って境界値を記述
  6. テストを記述
  7. テストを実行
  8. uv run python ./scripts/coverage_checker.py FILENAME --update を使ってカバレッジを更新
  9. 100% でなければ 5-9 を再び TODO に追加

Coverage Checker Tool - Automated test coverage validation
This tool automatically validates that functions with boundary condition checklists
have corresponding test implementations.
Features:
1. Scans Python files for functions with boundary condition docstrings
2. Parses docstring checklists to extract required test cases
3. Locates corresponding test files and validates test method existence
4. Updates docstring checkboxes based on actual test coverage
5. Reports missing tests and coverage statistics
Usage:
python scripts/coverage_checker.py [file_or_directory]
