/init-deep
Generate hierarchical AGENTS.md files: root + complexity-scored subdirectories, produced by a size-formula-driven dag map-reduce (quick scanners -> unspecified-high writers) so the main session's context stays flat at any repo size.
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)
Size & route (main session) - ONE eval cell measures the repo and computes the node formula.
todo init the five phases; start/ each transition in real time.
done
Phase 1: Size & Route
Measure and compute in ONE eval cell - code, not mental arithmetic:
# Measure (tracked files minus vendored/generated: node_modules, .git, dist,
# build, out, vendor, target, coverage, lockfiles, minified and binary files)
S = total source bytes after exclusions
per_dir = source bytes per directory # bin-packing input
depth = max directory depth # respect --max-depth (default 3)
existing = every AGENTS.md / CLAUDE.md path # read the ROOT one now
# Formula
CHUNK = 400 * 1024 # ~100k tokens of source; a quick worker's usable window
# is ~150k over its fallback chain - leave room for its
# prompt and report
N_quick = ceil(S / CHUNK) # bin-pack WHOLE directories into chunks; a directory
# larger than one chunk splits at its children
N_high = ceil(N_quick / 12) # one reducer absorbs ~12 reports (~60k tokens) and
# still has room to spot-check real code
Route:
N_quick < 4 -> inline path below; a dag costs more than it saves.
N_quick > task.dag.max_nodes_per_run (default 64) -> raise the knob in omo config, or run one chained dag per top-level directory (multi-run composition, mass-ulw skill).
Otherwise -> dag path: emit CHUNKS = [{id, dirs, bytes}], assign each writer a directory SUBTREE (disjoint - no two writers own the same directory), and mkdir -p .omo/init-deep/reports .omo/init-deep/digests.
--create-new: read every existing AGENTS.md FIRST (still-true facts survive as scanner input), then delete all, then regenerate.
Inline path (N_quick < 4)
Small repo - skip the dag. Fire 2-4 parallel explore agents (structure, entry points, conventions, anti-patterns), for example:
task(subagent_type="explore", run_in_background=true, prompt="Project structure: map real layout via ast-grep structural search (sg/ast_grep MCP) + rg --files -> REPORT deviations from standard patterns")
Run the LSP/ast-grep code map yourself (lsp_symbols outlines + workspace inventory, lsp_find_references on top exports, ast-grep import/call shapes; when neither resolves, mark centrality unmeasured). Then score with the matrix below and write every file per the templates yourself. Phase 5 applies unchanged.
Phase 2: Map Wave - quick Scanners (dag)
Build and start the run in one eval JS cell with the dag SDK (OMO_DAG_SDK_ROOT); wave doctrine, the node prompt contract, and the failure playbook come from the mass-ulw skill's references/planning.md. One scanner node per chunk, category: "quick", no load_skills - scanners stay lean and their prompt is a rigid numbered extraction template. Quick workers extract; they never judge and never write AGENTS.md:
TASK: Extract knowledge-base facts for chunk <id> (<dirs>) of <repo-root>.
Steps, in order:
1. Inventory each directory in scope: file count, LOC, languages, entry files.
2. Public exports/symbols other code imports - lsp_symbols and ast-grep
import/call shapes, never file-name guesses.
3. Conventions that DEVIATE from stack defaults (configs, naming, layout).
4. Anti-patterns: DO NOT / NEVER / ALWAYS / DEPRECATED comments, forbidden patterns.
5. Hotspots: files >500 lines, high-reference symbols, complexity concentrations.
6. Build/test/dev commands touching these dirs.
DELIVERABLE: EXACTLY ONE file `.omo/init-deep/reports/<id>.md`, <=5k tokens, sections
`# CHUNK <id>` / `## INVENTORY` / `## EXPORTS` / `## CONVENTIONS` / `## ANTI-PATTERNS`
/ `## HOTSPOTS` / `## COMMANDS`; an empty section says `none`.
SCOPE: read only <dirs>; write only your report file. If an AGENTS.md exists in scope,
quote its still-true claims into the matching sections.
VERIFY: the report file exists and every section header is present.
STOP WHEN: the report is written and verified.
One writer node per subtree, dependsOn its chunks' scanner ids, load_skills: ["init-deep"] - every writer carries this file, so the scoring matrix and templates below ARE its instructions:
TASK: Own subtree <path>: produce its AGENTS.md files for the repo knowledge base.
Steps, in order:
1. Read your chunk reports: .omo/init-deep/reports/<ids>.md. Reports are claims,
not truth - spot-check real code wherever they conflict or look thin.
2. Score each directory with the init-deep Scoring Matrix; pick locations with the
Decision Rules (both are in the init-deep skill content loaded with this task).
3. Write each AGENTS.md per the templates and the File Writing Rule. 30-80 lines,
never repeating parent content.
4. Write .omo/init-deep/digests/<subtree-slug>.md, <=2k tokens: every location
written (score, one-line role) plus cross-subtree facts the root file must know.
SCOPE: write only inside <path> plus your digest file. Root AGENTS.md is OUT of scope.
VERIFY: every location chosen in step 2 exists on disk within line limits; digest exists.
STOP WHEN: files and digest are written and verified.
Phase 4: Root & Verify (same dag)
root-writer - category: "unspecified-high", load_skills: ["init-deep"], dependsOn every writer. Reads ONLY .omo/init-deep/digests/* plus the existing root AGENTS.md; writes the root file per the template below. Never reads chunk reports.
verify - category: "quick", dependsOn root-writer. Checks: every digest-declared path exists; root is 50-150 lines; subdirectory files 30-80; no child repeats a parent section block. DELIVERABLE: one PASS / FAIL <path>: <reason> line per file.
The main session reads the verify node's output and nothing else. Each FAIL line -> dag send the owning writer with the named defect (or retry it), then re-run verify. Loop until all PASS. Fixing files yourself by reading reports is a defect - repair flows through the dag.
Scoring & Location (each writer applies this to its subtree; the inline path applies it repo-wide)
## WHERE TO LOOK
| Task | Location | Notes |
|------|----------|-------|
## CODE MAP
{From LSP/ast-grep - 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
30-80 lines max. Sections: OVERVIEW (1 line), STRUCTURE (only if >5 subdirs), WHERE TO LOOK, CONVENTIONS (only if different from parent), ANTI-PATTERNS. NEVER repeat parent content; note why the directory earned its file (score, distinct domain).

## Phase 5: Snapshot & Mode
Ask the user: **Local or committed?**
Capture the answer as `USER_MODE_CHOICE`. The explicit answer is authoritative:
- `local` keeps the generated guidance personal to this checkout.
- `committed` reruns the change through the `work-with-pr` skill so the generated guidance lands through a reviewed PR.
- If no explicit answer is available, tracked `AGENTS.md` status is the fallback.
Run these commands after the review is complete:
```bash
# Snapshot — create complete JSON with all fields, milliseconds timestamp
mkdir -p .omo
SHA=$(git rev-parse HEAD)
# Count tracked files (NUL byte counting, chunk-boundary safe)
FILES=$(git ls-files -z | node -e 'let c=0;process.stdin.on("data",d=>{for(let i=0;i<d.length;i++)if(d[i]===0)c++});process.stdin.on("end",()=>process.stdout.write(String(c)))')
LOC=$(git ls-files -z -- '*.ts' '*.tsx' '*.js' '*.jsx' '*.py' '*.go' '*.rs' '*.java' '*.kt' '*.swift' '*.rb' '*.php' '*.c' '*.cpp' '*.cs' '*.scala' '*.lua' '*.ex' '*.exs' '*.zig' '*.dart' | xargs -0 wc -l 2>/dev/null | tail -1 | awk '{print $1}')
NOW=$(node -e 'console.log(Date.now())')
USER_MODE_CHOICE="${USER_MODE_CHOICE:-}" && if [ "$USER_MODE_CHOICE" = "committed" ]; then MODE=committed; elif [ "$USER_MODE_CHOICE" = "local" ]; then MODE=local; elif git ls-files --error-unmatch AGENTS.md >/dev/null 2>&1; then MODE=committed; else MODE=local; fi
cat > .omo/init-deep.json <<EOF
{"commitSha":"$SHA","fileCount":$FILES,"loc":${LOC:-0},"timestamp":$NOW,"mode":"$MODE"}
EOF
# Local mode exclude — managed block (idempotent, never clobbers user lines)
if [ "$MODE" = "local" ]; then
EXCLUDE=$(git rev-parse --git-path info/exclude)
mkdir -p "$(dirname "$EXCLUDE")"
if ! grep -q '# >>> omo-senpi init-deep local (managed)' "$EXCLUDE" 2>/dev/null; then
cat >> "$EXCLUDE" <<'BLOCK'
# >>> omo-senpi init-deep local (managed)
# Do not edit this block; rerun init-deep or switch modes.
/.omo/init-deep.json
AGENTS.md
# <<< omo-senpi init-deep local (managed)
BLOCK
fi
fi
# Nested AGENTS.md discovery
find . -name AGENTS.md -not -path '*/node_modules/*' -not -path '*/.git/*' -not -path '*/dist/*' -not -path '*/build/*'
When switching from local mode to committed mode, remove the managed block before rerunning through work-with-pr:
EXCLUDE=$(git rev-parse --git-path info/exclude) && sed -i.bak "/# >>> omo-senpi init-deep local (managed)/,/# <<< omo-senpi init-deep local (managed)/d" "$EXCLUDE" && rm -f "$EXCLUDE.bak"
USER_MODE_CHOICE=committed selects committed mode even when AGENTS.md is untracked. USER_MODE_CHOICE=local selects local mode even when AGENTS.md is tracked. .git/info/exclude cannot hide changes to an already tracked file, so explicit local mode on a tracked AGENTS.md is informational only and the file remains visible to git.
Cleanup
After the snapshot: rm -rf .omo/init-deep - reports and digests are ephemeral scaffolding; .omo/init-deep.json is the only artifact that stays. Record the removal in the final report.
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
