init-deep

name	init-deep
description	(builtin) Initialize hierarchical AGENTS.md knowledge base

/init-deep

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

Local ocmm/OpenCode Notes

• Use OpenCode task(...) delegation syntax where available.
• explore is provided as a compatibility alias for local code-search.
• Use category="documenting" for AGENTS.md writing tasks; upstream examples that say category="writing" should be translated to documenting.
• Treat codegraph_* tools as optional. If they are unavailable, use LSP tools, rg, and the ast-grep skill as the fallback evidence path.

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/codegraph code map + 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

**TodoWrite ALL phases. Mark in_progress → completed in real-time.** ``` TodoWrite([ { id: "discovery", content: "Fire explore agents + LSP/codegraph map + 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" } ]) ```

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. Equip every agent with the code graph: any task touching structure, entry points, dependencies, or hotspots MUST query codegraph_* (explore/search/callers/callees/impact) and lsp_symbols when present, and ground its claims in that data instead of guessing from conventions. Richer real-graph context per agent = a more accurate project map.

// Fire all at once, collect results later
task(subagent_type="explore", load_skills=[], description="Explore project structure", run_in_background=true, prompt="Project structure: map real layout via codegraph_explore/codegraph_files → REPORT deviations from standard patterns")
task(subagent_type="explore", load_skills=[], description="Find entry points", run_in_background=true, prompt="Entry points: FIND main files, trace reach via codegraph_callees + lsp_symbols → 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/structure; codegraph_callers on core modules to see what is covered → 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. Code Map - drive LSP AND codegraph (do NOT skip)

Highest-signal source for the CODE MAP and the Symbol/Export/Reference scoring rows. Complementary, not alternatives - run BOTH when present, alongside the explore agents.

LSP - check lsp_status; model-facing names are lsp_status/lsp_symbols/lsp_find_references/lsp_goto_definition (some harnesses drop the lsp_ prefix):

• lsp_symbols scope="document" on each entry point -> file outline.
• lsp_symbols scope="workspace", query by kind (class/interface/function) -> symbol inventory.
• lsp_find_references on top exports (line/character from the symbols result) -> reference centrality.

codegraph - when codegraph_* tools exist (check codegraph_status); a first-class peer to LSP, NOT a last resort:

• codegraph_explore -> overview; codegraph_callers/codegraph_callees/codegraph_impact -> centrality + blast radius for the scoring matrix; codegraph_search/codegraph_files -> symbol/file inventory.

Only if NEITHER exists: explore agents + the ast-grep skill (sg), and mark centrality unmeasured in the CODE MAP.

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/codegraph + 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/cg
Export count	2x	>10 exports	LSP/cg
Reference centrality	3x	>20 refs	LSP/cg

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.

**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/codegraph - skip only if neither exists 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 writing tasks for each location:

for loc in AGENTS_LOCATIONS (except root): task(category="documenting", load_skills=[], run_in_background=false, description="Generate AGENTS.md", prompt= Generate AGENTS.md for: ${loc.path} - Reason: ${loc.reason} - 30-80 lines max - NEVER repeat parent content - Sections: OVERVIEW (1 line), STRUCTURE (if >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.**

## Anti-Patterns

- **Static agent count**: MUST vary agents based on project size/depth
- **Sequential execution**: MUST parallel (explore + LSP + codegraph 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
