feat(code-index): add auto-initialization and percentage-based progress logging

akiojin · claude · akiojin · commit 52e738ac25e8 · 2025-11-18T05:21:58.000Z
起動時にコードインデックスDBが存在しない場合、自動的にバックグラウンドでビルドを開始し、60秒タイムアウトエラーを解消する。また、進捗ログを一定パーセンテージごとに出力し、開発者が進行状況を把握しやすくする。 主な変更: - server.js: 起動時にcode_index_buildを自動実行 - CodeIndexBuildToolHandler.js: 10%ごとのパーセンテージベースログ出力 - spec.md: FR-010追加（パーセンテージベースのログ要件） - tests: FR-010準拠のユニットテスト6件追加 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
