# index-knowledge Generate hierarchical AGENTS.md files. Root + complexity-scored subdirectories. ## Usage ``` --create-new # Read existing → remove all → regenerate from scratch --max-depth=2 # Limit directory depth (default: 5) ``` Default: Update mode (modify existing + create new where warranted) --- ## Workflow (High-Level) 1. **Discovery + Analysis** (concurrent) - Launch parallel explore agents (multiple Task calls in one message) - Main session: bash structure + LSP codemap + read existing AGENTS.md 2. **Score & Decide** - Determine AGENTS.md locations from merged findings 3. **Generate** - Root first, then subdirs in parallel 4. **Review** - Deduplicate, trim, validate <critical> **TodoWrite ALL phases. Mark in_progress → completed in real-time.** ``` TodoWrite([ { id: "discovery", content: "Fire explore agents + LSP codemap + read existing", status: "pending", priority: "high" }, { id: "scoring", content: "Score directories, determine locations", status: "pending", priority: "high" }, { id: "generate", content: "Generate AGENTS.md files (root + subdirs)", status: "pending", priority: "high" }, { id: "review", content: "Deduplicate, validate, trim", status: "pending", priority: "medium" } ]) ``` </critical> --- ## Phase 1: Discovery + Analysis (Concurrent) **Mark "discovery" as in_progress.** ### Launch Parallel Explore Agents Multiple Task calls in a single message execute in parallel. Results return directly. ``` // All Task calls in ONE message = parallel execution Task( description="project structure", subagent_type="explore", prompt="Project structure: PREDICT standard patterns for detected language → REPORT deviations only" ) Task( description="entry points", subagent_type="explore", prompt="Entry points: FIND main files → REPORT non-standard organization" ) Task( description="conventions", subagent_type="explore", prompt="Conventions: FIND config files (.eslintrc, pyproject.toml, .editorconfig) → REPORT project-specific rules" ) Task( description="anti-patterns", subagent_type="explore", prompt="Anti-patterns: FIND 'DO NOT', 'NEVER', 'ALWAYS', 'DEPRECATED' comments → LIST forbidden patterns" ) Task( description="build/ci", subagent_type="explore", prompt="Build/CI: FIND .github/workflows, Makefile → REPORT non-standard patterns" ) Task( description="test patterns", subagent_type="explore", prompt="Test patterns: FIND test configs, test structure → REPORT unique conventions" ) ``` <dynamic-agents> **DYNAMIC AGENT SPAWNING**: After bash analysis, spawn ADDITIONAL explore agents based on project scale: | Factor | Threshold | Additional Agents | | ---------------------------- | --------- | -------------------------- | | **Total files** | >100 | +1 per 100 files | | **Total lines** | >10k | +1 per 10k lines | | **Directory depth** | ≥4 | +2 for deep exploration | | **Large files (>500 lines)** | >10 files | +1 for complexity hotspots | | **Monorepo** | detected | +1 per package/workspace | | **Multiple languages** | >1 | +1 per language | ```bash # Measure project scale first total_files=$(find . -type f -not -path '*/node_modules/*' -not -path '*/.git/*' | wc -l) total_lines=$(find . -type f \( -name "*.ts" -o -name "*.py" -o -name "*.go" \) -not -path '*/node_modules/*' -exec wc -l {} + 2>/dev/null | tail -1 | awk '{print $1}') large_files=$(find . -type f \( -name "*.ts" -o -name "*.py" \) -not -path '*/node_modules/*' -exec wc -l {} + 2>/dev/null | awk '$1 > 500 {count++} END {print count+0}') max_depth=$(find . -type d -not -path '*/node_modules/*' -not -path '*/.git/*' | awk -F/ '{print NF}' | sort -rn | head -1) ``` Example spawning (all in ONE message for parallel execution): ``` // 500 files, 50k lines, depth 6, 15 large files → spawn additional agents Task( description="large files", subagent_type="explore", prompt="Large file analysis: FIND files >500 lines, REPORT complexity hotspots" ) Task( description="deep modules", subagent_type="explore", prompt="Deep modules at depth 4+: FIND hidden patterns, internal conventions" ) Task( description="cross-cutting", subagent_type="explore", prompt="Cross-cutting concerns: FIND shared utilities across directories" ) // ... more based on calculation ``` </dynamic-agents> ### Main Session: Concurrent Analysis **While Task agents execute**, main session does: #### 1. Bash Structural Analysis ```bash # Directory depth + file counts find . -type d -not -path '*/\.*' -not -path '*/node_modules/*' -not -path '*/venv/*' -not -path '*/dist/*' -not -path '*/build/*' | awk -F/ '{print NF-1}' | sort -n | uniq -c # Files per directory (top 30) find . -type f -not -path '*/\.*' -not -path '*/node_modules/*' | sed 's|/[^/]*$||' | sort | uniq -c | sort -rn | head -30 # Code concentration by extension find . -type f \( -name "*.py" -o -name "*.ts" -o -name "*.tsx" -o -name "*.js" -o -name "*.go" -o -name "*.rs" \) -not -path '*/node_modules/*' | sed 's|/[^/]*$||' | sort | uniq -c | sort -rn | head -20 # Existing AGENTS.md / CLAUDE.md find . -type f \( -name "AGENTS.md" -o -name "CLAUDE.md" \) -not -path '*/node_modules/*' 2>/dev/null ``` #### 2. Read Existing AGENTS.md ``` For each existing file found: Read(filePath=file) Extract: key insights, conventions, anti-patterns Store in EXISTING_AGENTS map ``` If `--create-new`: Read all existing first (preserve context) → then delete all → regenerate. #### 3. LSP Codemap (if available) ``` lsp_servers() # Check availability # Entry points (parallel) lsp_document_symbols(filePath="src/index.ts") lsp_document_symbols(filePath="main.py") # Key symbols (parallel) lsp_workspace_symbols(filePath=".", query="class") lsp_workspace_symbols(filePath=".", query="interface") lsp_workspace_symbols(filePath=".", query="function") # Centrality for top exports lsp_find_references(filePath="...", line=X, character=Y) ``` **LSP Fallback**: If unavailable, rely on explore agents + AST-grep. **Merge: bash + LSP + existing + Task agent results. Mark "discovery" as completed.** --- ## Phase 2: Scoring & Location Decision **Mark "scoring" as in_progress.** ### Scoring Matrix | Factor | Weight | High Threshold | Source | | -------------------- | ------ | ------------------------ | ------- | | File count | 3x | >20 | bash | | Subdir count | 2x | >5 | bash | | Code ratio | 2x | >70% | bash | | Unique patterns | 1x | Has own config | explore | | Module boundary | 2x | Has index.ts/**init**.py | bash | | Symbol density | 2x | >30 symbols | LSP | | Export count | 2x | >10 exports | LSP | | Reference centrality | 3x | >20 refs | LSP | ### Decision Rules | Score | Action | | ------------ | ------------------------- | | **Root (.)** | ALWAYS create | | **>15** | Create AGENTS.md | | **8-15** | Create if distinct domain | | **<8** | Skip (parent covers) | ### Output ``` AGENTS_LOCATIONS = [ { path: ".", type: "root" }, { path: "src/hooks", score: 18, reason: "high complexity" }, { path: "src/api", score: 12, reason: "distinct domain" } ] ``` **Mark "scoring" as completed.** --- ## Phase 3: Generate AGENTS.md **Mark "generate" as in_progress.** ### Root AGENTS.md (Full Treatment) ```markdown # PROJECT KNOWLEDGE BASE **Generated:** {TIMESTAMP} **Commit:** {SHORT_SHA} **Branch:** {BRANCH} ## OVERVIEW {1-2 sentences: what + core stack} ## STRUCTURE \`\`\` {root}/ ├── {dir}/ # {non-obvious purpose only} └── {entry} \`\`\` ## WHERE TO LOOK | Task | Location | Notes | | ---- | -------- | ----- | ## CODE MAP {From LSP - skip if unavailable or project <10 files} | Symbol | Type | Location | Refs | Role | ## CONVENTIONS {ONLY deviations from standard} ## ANTI-PATTERNS (THIS PROJECT) {Explicitly forbidden here} ## UNIQUE STYLES {Project-specific} ## COMMANDS \`\`\`bash {dev/test/build} \`\`\` ## NOTES {Gotchas} ``` **Quality gates**: 50-150 lines, no generic advice, no obvious info. ### Subdirectory AGENTS.md (Parallel) Launch general agents for each location in ONE message (parallel execution): ``` // All in single message = parallel Task( description="AGENTS.md for src/hooks", subagent_type="general", prompt="Generate AGENTS.md for: src/hooks - Reason: high complexity - 30-80 lines max - NEVER repeat parent content - Sections: OVERVIEW (1 line), STRUCTURE (if >5 subdirs), WHERE TO LOOK, CONVENTIONS (if different), ANTI-PATTERNS - Write directly to src/hooks/AGENTS.md" ) Task( description="AGENTS.md for src/api", subagent_type="general", prompt="Generate AGENTS.md for: src/api - Reason: distinct domain - 30-80 lines max - NEVER repeat parent content - Sections: OVERVIEW (1 line), STRUCTURE (if >5 subdirs), WHERE TO LOOK, CONVENTIONS (if different), ANTI-PATTERNS - Write directly to src/api/AGENTS.md" ) // ... one Task per AGENTS_LOCATIONS entry ``` **Results return directly. Mark "generate" as completed.** --- ## Phase 4: Review & Deduplicate **Mark "review" as in_progress.** For each generated file: - Remove generic advice
