Repository Indexing for Token Efficiency

Problem: Loading全ファイルで毎回50,000トークン消費 Solution: 最初だけインデックス作成、以降3,000トークンで済む (94%削減)

Auto-Execution

PM Mode Session Start:

index_path = Path("PROJECT_INDEX.md")
if not index_path.exists() or is_stale(index_path, days=7):
    print("🔄 Creating repository index...")
    # Execute indexing automatically
    uv run python superclaude/indexing/parallel_repository_indexer.py

Manual Trigger:

/sc:index-repo           # Full index
/sc:index-repo --quick   # Fast scan
/sc:index-repo --update  # Incremental

What It Does

Parallel Analysis (5 concurrent tasks)

1. Code structure (src/, lib/, superclaude/)
2. Documentation (docs/, *.md)
3. Configuration (.toml, .yaml, .json)
4. Tests (tests/, tests)
5. Scripts (scripts/, bin/, tools/)

Output Files

• PROJECT_INDEX.md - Human-readable (3KB)
• PROJECT_INDEX.json - Machine-readable (10KB)
• .superclaude/knowledge/agent_performance.json - Learning data

Token Efficiency

Before (毎セッション):

Read all .md files: 41,000 tokens
Read all .py files: 15,000 tokens
Glob searches: 2,000 tokens
Total: 58,000 tokens

After (インデックス使用):

Read PROJECT_INDEX.md: 3,000 tokens
Direct file access: 1,000 tokens
Total: 4,000 tokens

Savings: 93% (54,000 tokens)

Usage in Sessions

# Session start
index = read_file("PROJECT_INDEX.md")  # 3,000 tokens

# Navigation
"Where is the validator code?"
→ Index says: superclaude/validators/
→ Direct read, no glob needed

# Understanding
"What's the project structure?"
→ Index has full overview
→ No need to scan all files

# Implementation
"Add new validator"
→ Index shows: tests/validators/ exists
→ Index shows: 5 existing validators
→ Follow established pattern

Integration with Setup

# setup/components/knowledge_base.py

def install_knowledge_base():
    """Install framework knowledge"""
    # ... existing installation ...

    # Auto-create repository index
    print("\n📊 Creating repository index...")
    run_indexing()
    print("✅ Index created - 93% token savings enabled")

When to Re-Index

Auto-triggers:

• セットアップ時 (初回のみ)
• INDEX.mdが7日以上古い
• PM Modeセッション開始時にチェック

Manual re-index:

• 大規模リファクタリング後 (>20 files)
• 新機能追加後 (new directories)
• 週1回 (active development)

Skip:

• 小規模編集 (<5 files)
• ドキュメントのみ変更
• INDEX.mdが24時間以内

Performance

Speed:

• Large repo (500+ files): 3-5 min
• Medium repo (100-500 files): 1-2 min
• Small repo (<100 files): 10-30 sec

Self-Learning:

• Tracks agent performance
• Optimizes future runs
• Stored in .superclaude/knowledge/
