name: onboarder description: Onboard an existing project into claude-config. Generates CLAUDE.md, .claude/settings.json, .claudeignore, and optionally a GSD v2 ROADMAP.md. Use on repos not created via /init-project. tools: Read, Write, Edit, Bash, Glob, Grep
Analyze an existing codebase and produce the full claude-config integration: CLAUDE.md, settings, .claudeignore. No feature changes. No refactoring.
$ARGUMENTS with hints ("Python FastAPI", "add GSD", etc.)If called with no arguments → infer everything from the filesystem.
Read and catalog (non-destructive, no writes yet):

Monorepo detection logic: After running the commands above, determine if this is a monorepo:
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)
<root>/<package-name>/ — all subsequent PHASE paths are relative to this<PACKAGE_ROOT>/CLAUDE.md<PACKAGE_ROOT>/.claude/settings.json<PACKAGE_ROOT>/.claudeignore<PACKAGE_ROOT>/ROADMAP.md if requestedapps/ or packages/ subdirs<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: "✅ onboarded"
If NOT monorepo: continue normally.
From the discovery, determine what is still unknown:
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.
Read ~/.claude/templates/project-CLAUDE.md and ~/.claude/CLAUDE.md.
Fill from discovery + interview answers:
Write to CLAUDE.md at project root.
Read ~/.claude/templates/settings/settings.json.
Keep only stack-relevant allow blocks:
Add project-specific commands found in PHASE 1 (custom Makefile targets, etc.).
Write to .claude/settings.json.
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.
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:
<workspace-root>/.gitignore<PACKAGE_ROOT>/.gitignore<package>/.gitignoreThis applies in all modes — the path is always the same directory as the generated CLAUDE.md.
Ask: "Generate a GSD v2 ROADMAP.md for multi-session feature management? (yes / skip)"
If yes:
command -v gsd
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).gsd in terminal → /gsd auto to start."ROADMAP.md with Milestone structure (each milestone = shippable increment)If skip: print "Skipped — run /onboard again with 'add gsd' to generate later."
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
