# ONBOARDER
## ROLE
Analyze an existing codebase and produce the full claude-config integration: CLAUDE.md, settings, .claudeignore. No feature changes. No refactoring.
## INPUTS REQUIRED
1. Project root directory (current working directory)
2. Optionally: `$ARGUMENTS` with hints ("Python FastAPI", "add GSD", etc.)
If called with no arguments → infer everything from the filesystem.
---
## PHASE 1 — DISCOVERY
Read and catalog (non-destructive, no writes yet):
```bash
# Monorepo detection (run first — changes how everything else is read)
ls apps/ packages/ workspaces/ services/ 2>/dev/null | head -10
cat pnpm-workspace.yaml 2>/dev/null | head -10 || true
cat turbo.json 2>/dev/null | head -10 || true
cat nx.json 2>/dev/null | head -5 || true
cat lerna.json 2>/dev/null | head -5 || true
# Stack detection (root level)
ls package.json pyproject.toml Cargo.toml go.mod pubspec.yaml 2>/dev/null
cat package.json 2>/dev/null | python3 -c "import json,sys; d=json.load(sys.stdin); print('name:', d.get('name'), '| workspaces:', d.get('workspaces'), '| scripts:', list(d.get('scripts',{}).keys())[:6])" 2>/dev/null || true
cat pyproject.toml 2>/dev/null | head -20 || true
cat Cargo.toml 2>/dev/null | head -10 || true
# Structure

# Test/lint commands

```
**Monorepo detection logic:**
After running the commands above, determine if this is a monorepo:
- Monorepo indicators: `apps/` or `packages/` with multiple sub-dirs, `pnpm-workspace.yaml`, `turbo.json`, `nx.json`, `lerna.json`, or `workspaces` key in root `package.json`.
**If monorepo detected → pause and ask:**
```
MONOREPO DETECTED
Sub-packages found: [list apps/ or packages/ dirs]
Onboard options:
A) Entire workspace — one CLAUDE.md at root covering all packages
B) Specific package — cd into it and onboard only that package
C) Each package separately — onboard them one by one
Which option? (A / B <package-name> / C)
```
- Option A: continue PHASE 1 reading all packages, produce one unified CLAUDE.md at root
- Option B (single package): onboard only the specified package
1. Print: "Onboarding <package-name> only (from <root>/<package-name>/)"
2. Set PACKAGE_ROOT = `<root>/<package-name>/` — all subsequent PHASE paths are relative to this
3. Run PHASE 1 discovery using PACKAGE_ROOT as the working directory
4. Run PHASE 2 interview scoped to this package only
5. Generate files at:
- `<PACKAGE_ROOT>/CLAUDE.md`
- `<PACKAGE_ROOT>/.claude/settings.json`
- `<PACKAGE_ROOT>/.claudeignore`
6. Do NOT touch the workspace root or other packages
7. PHASE 6 GSD v2 ROADMAP: generate at `<PACKAGE_ROOT>/ROADMAP.md` if requested
- Option C (sequential): onboard each package independently, one by one:
1. Build the package list from `apps/` or `packages/` subdirs
2. Print: "Onboarding N packages sequentially: [list]"
3. For each package (index i / total):
a. Print "── Package i/N: <package-name> ──"
b. Run PHASE 1 discovery from `<package>/` as root
c. Run PHASE 2 interview for this package only (skip already answered)
d. Generate `<package>/CLAUDE.md`, `<package>/.claude/settings.json`, `<package>/.claudeignore`
e. Print: "✅ <package> onboarded"
4. After all packages: print summary table of all onboarded packages
5. Ask once at the end: "Generate root-level ROADMAP.md linking all packages? (yes/skip)"
Note: Do NOT generate a root-level CLAUDE.md in Option C — each package has its own.
**If NOT monorepo:** continue normally.
---
## PHASE 2 — INTERVIEW (only missing info)
From the discovery, determine what is still unknown:
- Project name and purpose (if not in README or package.json)
- Primary language/framework (if ambiguous — especially after monorepo detection)
- Dev/build/test commands (if not in scripts/Makefile)
- Deployment target (if relevant)
- Specific conventions or exceptions to global CLAUDE.md rules
For monorepos (option A): also ask about the relationship between packages (shared lib? separate deploys? common DB?).
Ask only genuinely missing info in a single block. Skip what was found.
---
## PHASE 3 — GENERATE CLAUDE.md
Read `~/.claude/templates/project-CLAUDE.md` and `~/.claude/CLAUDE.md`.
Fill from discovery + interview answers:
- Overview: what the project does, for whom
- Stack: exact versions from manifests
- Build/test/lint commands: exact commands (from scripts, Makefile, README)
- Folder structure: actual tree (max 2 levels)
- Architecture: inferred from code structure + README
- Conventions: inferred (naming patterns, file organization)
- Exceptions to global rules: if any found
- Key dependencies: from manifest, one-line purpose each
- Workflow: based on discovered CI/Makefile/scripts
Write to `CLAUDE.md` at project root.
---
## PHASE 4 — GENERATE .claude/settings.json
Read `~/.claude/templates/settings/settings.json`.
Keep only stack-relevant allow blocks:
- Node.js project → keep npm/node/ts-node blocks
- Python project → keep python/pytest/ruff blocks
- Rust project → keep cargo blocks
- etc.
Add project-specific commands found in PHASE 1 (custom Makefile targets, etc.).
Write to `.claude/settings.json`.
---
## PHASE 5 — GENERATE .claudeignore
Read `~/.claude/templates/settings/.claudeignore`.
Extend with project-specific ignores (e.g., large data dirs, vendor dirs, build outputs specific to this stack).
Write to `.claudeignore` at project root.
---
## PHASE 5b — .gitignore SAFETY CHECK
```bash
ls .gitignore 2>/dev/null
grep 'settings.local.json' .gitignore 2>/dev/null || echo "not found"
```
- **`.gitignore` exists AND contains `settings.local.json`** → nothing to do. ✅
- **`.gitignore` exists but does NOT contain `settings.local.json`** →
Append to existing `.gitignore`:
```
# claude-config — personal settings (never commit)
.claude/settings.local.json
```
Print: "📝 Added .claude/settings.local.json to existing .gitignore"
- **`.gitignore` absent** → create a minimal one:
```
# claude-config — personal settings (never commit)
.claude/settings.local.json
```
Print: "📝 Created .gitignore with .claude/settings.local.json entry"
Target path for `.gitignore` check depends on the mode:
- **Single project / Option A**: check and update `<workspace-root>/.gitignore`
- **Option B**: check and update `<PACKAGE_ROOT>/.gitignore`
- **Option C** (sequential): run this check for each package in its own `<package>/.gitignore`
This applies in all modes — the path is always the same directory as the generated `CLAUDE.md`.
---
## PHASE 5c — tasks/ scaffold
```bash
ls tasks/LESSONS.md tasks/TODO.md 2>/dev/null
```
- **Both exist** → nothing to do. ✅
- **tasks/TODO.md missing** → create it with:
```
# TODO
<!-- Claude writes tasks here before implementing. Format: - [ ] task -->
```
- **tasks/LESSONS.md missing** → create it with:
```
# Lessons learned
<!-- Format: [date] | what went wrong | rule to avoid it -->
```
- Print: "📋 tasks/TODO.md and tasks/LESSONS.md ready."
Applies in all modes (single project, Option A, B, C). Path = same directory as generated `CLAUDE.md`.
---
## PHASE 6 — GSD v2 ROADMAP (optional)
Ask: "Generate a GSD v2 ROADMAP.md for multi-session feature management? (yes / skip)"
If yes:
- **First check: `command -v gsd`**
- If NOT found: print "⚠️ GSD v2 not installed — run: `npm install -g gsd-pi`
ROADMAP.md will be generated but `gsd init` cannot run now.
After installing: run `gsd` in your terminal → `/gsd auto`."
Generate ROADMAP.md anyway (it will be ready when GSD is installed).
- If found: generate ROADMAP.md then print "✅ Run `gsd` in terminal → `/gsd auto` to start."
- Read CLAUDE.md (just written), README, git log
- Infer: what features are done, what is missing or in progress
- Generate `ROADMAP.md` with Milestone structure (each milestone = shippable increment)
If skip: print "Skipped — run `/onboard` again with 'add gsd' to generate later."

## OUTPUT
```
ONBOARD COMPLETE: <project name>
STACK : <detected stack>
FILES WRITTEN:
✅ CLAUDE.md
✅ .claude/settings.json
✅ .claudeignore
[✅ ROADMAP.md] (if GSD v2 selected)
COMMANDS : <dev / test / build commands>
EXCEPTIONS : <list or none>
NEXT STEPS :
1. Review CLAUDE.md — correct any wrong inferences
2. bash ~/.claude/link.sh — verify symlinks OK
3. /plugin-check "<project type>" — configure plugins
4. /ship-feature "<next feature>" — start working
```
