Init Deep

/init-deep

Generate hierarchical AGENTS.md files. Root + complexity-scored subdirectories.

Usage

/init-deep                      # Update mode: modify existing + create new where warranted
/init-deep --create-new         # Read existing → remove all → regenerate from scratch
/init-deep --max-depth=2        # Limit directory depth (default: 3)

Workflow (High-Level)

1. Discovery + Analysis (concurrent)

• Fire background explore agents immediately
• Main session: bash structure + LSP codemap + read existing AGENTS.md

1. Score & Decide - Determine AGENTS.md locations from merged findings
2. Generate - Root first, then subdirs in parallel
3. Review - Deduplicate, trim, validate

TodoWrite ALL phases. Mark in_progress → completed in real-time.

Phase 1: Discovery + Analysis (Concurrent)

Mark "discovery" as in_progress.

Fire Background Explore Agents IMMEDIATELY

Don't wait-these run async while main session works.

// Fire all at once, collect results later
task(subagent_type="explore", load_skills=[], description="Explore project structure", run_in_background=true, prompt="Project structure: PREDICT standard patterns for detected language → REPORT deviations only")
task(subagent_type="explore", load_skills=[], description="Find entry points", run_in_background=true, prompt="Entry points: FIND main files → REPORT non-standard organization")
task(subagent_type="explore", load_skills=[], description="Find conventions", run_in_background=true, prompt="Conventions: FIND config files (.eslintrc, pyproject.toml, .editorconfig) → REPORT project-specific rules")
task(subagent_type="explore", load_skills=[], description="Find anti-patterns", run_in_background=true, prompt="Anti-patterns: FIND 'DO NOT', 'NEVER', 'ALWAYS', 'DEPRECATED' comments → LIST forbidden patterns")
task(subagent_type="explore", load_skills=[], description="Explore build/CI", run_in_background=true, prompt="Build/CI: FIND .github/workflows, Makefile → REPORT non-standard patterns")
task(subagent_type="explore", load_skills=[], description="Find test patterns", run_in_background=true, prompt="Test patterns: FIND test configs, test structure → REPORT unique conventions")

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 |

# 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:

// 500 files, 50k lines, depth 6, 15 large files → spawn 5+5+2+1 = 13 additional agents
task(subagent_type="explore", load_skills=[], description="Analyze large files", run_in_background=true, prompt="Large file analysis: FIND files >500 lines, REPORT complexity hotspots")
task(subagent_type="explore", load_skills=[], description="Explore deep modules", run_in_background=true, prompt="Deep modules at depth 4+: FIND hidden patterns, internal conventions")
task(subagent_type="explore", load_skills=[], description="Find shared utilities", run_in_background=true, prompt="Cross-cutting concerns: FIND shared utilities across directories")
// ... more based on calculation

Main Session: Concurrent Analysis

While background agents run, main session does:

1. Bash Structural Analysis

# 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)

LspServers()  # Check availability

# Entry points (parallel)
LspDocumentSymbols(filePath="src/index.ts")
LspDocumentSymbols(filePath="main.py")

# Key symbols (parallel)
LspWorkspaceSymbols(filePath=".", query="class")
LspWorkspaceSymbols(filePath=".", query="interface")
LspWorkspaceSymbols(filePath=".", query="function")

# Centrality for top exports
LspFindReferences(filePath="...", line=X, character=Y)

LSP Fallback: If unavailable, rely on explore agents + AST-grep.

Collect Background Results

// After main session analysis done, collect all task results
for each background task ID (`bg_...`): background_output(task_id="bg_...")

Merge: bash + LSP + existing + explore findings. 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 | | File Writing Rule**: If AGENTS.md already exists at the target path → use Edit tool. If it does NOT exist → use Write tool. NEVER use Write to overwrite an existing file. ALWAYS check existence first via Read or discovery results.

Root AGENTS.md (Full Treatment)

# 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 5 subdirs), WHERE TO LOOK, CONVENTIONS (if different), ANTI-PATTERNS
  `)

Wait for all. Mark "generate" as completed.

---

Phase 4: Review & Deduplicate

Mark "review" as in_progress.

For each generated file:

• Remove generic advice
• Remove parent duplicates
• Trim to size limits
• Verify telegraphic style

Mark "review" as completed.

Final Report

Anti-Patterns

• Static agent count: MUST vary agents based on project size/depth
• Sequential execution: MUST parallel (explore + LSP concurrent)
• Ignoring existing: ALWAYS read existing first, even with --create-new
• Over-documenting: Not every dir needs AGENTS.md
• Redundancy: Child never repeats parent
• Generic content: Remove anything that applies to ALL projects
• Verbose style: Telegraphic or die
