setup

Setup

Interactive, Claude-guided setup for metaswarm. Detects your stack, asks targeted questions, writes project-local files, and creates command shims. Replaces both npx metaswarm init and the old /metaswarm-setup command.

<CRITICAL-REQUIREMENTS> Setup MUST produce these 3 mandatory outputs. A shell script handles them automatically — you MUST run it.

After Phase 2 (user questions), determine the correct coverage command from the detection results, then run this Bash command:

bash "${CLAUDE_PLUGIN_ROOT}/lib/setup-mandatory-files.sh" "$(pwd)" <threshold> "<coverage-command>"

Where:

• <threshold> is the user's chosen percentage (e.g., 100)
• <coverage-command> is the enforcement command for their test runner:
  • pytest → "pytest --cov --cov-fail-under=<threshold>"
  • vitest/pnpm → "pnpm vitest run --coverage"
  • jest/npm → "npx jest --coverage"
  • go → "go test -coverprofile=coverage.out ./..."
  • cargo → "cargo tarpaulin --fail-under <threshold>"

The script handles:

1. CLAUDE.md — appends metaswarm section (or writes new), skips if already present
2. .coverage-thresholds.json — writes at project root with correct thresholds and command
3. 6 shims in .claude/commands/ — writes start-task.md, prime.md, review-design.md, self-reflect.md, pr-shepherd.md, brainstorm.md

The script outputs JSON with what was created/skipped/errored. Check that "status": "ok".

If the script is not available or fails, fall back to writing these files manually with the Write tool. Do NOT skip them. </CRITICAL-REQUIREMENTS>

Pre-Flight

Existing Profile Check

Use Glob to check if .metaswarm/project-profile.json exists.

• If it exists: Read it, present the current configuration summary, and ask the user via AskUserQuestion: "You already have a metaswarm project profile. Re-run setup (overwrites choices) or skip?" Options: "Re-run setup" / "Skip". If the user skips, stop with: "Setup skipped. Existing configuration unchanged."
• If it does not exist: Continue to Project Detection.

---

Phase 1: Project Detection

Scan the project directory silently using Glob and Read. Do NOT ask the user for any of this information. Detect everything, then present results.

1.1 Language

Check for marker files at the project root:

Marker File	Language
package.json	Node.js / JavaScript
tsconfig.json	TypeScript (refines Node.js to TypeScript)
pyproject.toml OR setup.py OR requirements.txt	Python
go.mod	Go
Cargo.toml	Rust
pom.xml OR build.gradle OR build.gradle.kts	Java
Gemfile	Ruby
Makefile (alone, no other markers)	Unknown (ask user)

If tsconfig.json exists alongside package.json, the language is "TypeScript".

If multiple languages are detected, note all of them but use the primary one (most infrastructure) for command generation.

If no language detected: Use AskUserQuestion to ask the user what language/stack they are using before proceeding.

1.2 Framework

Node.js/TypeScript — Read package.json and check dependencies + devDependencies:

Dependency	Framework
next	Next.js
nuxt OR nuxt3	Nuxt
@angular/core	Angular
svelte OR @sveltejs/kit	SvelteKit
react (without next/nuxt)	React
vue (without nuxt)	Vue
express	Express
fastify	Fastify
hono	Hono
@nestjs/core	NestJS

Python — Check pyproject.toml or requirements.txt for: fastapi, django, flask.

Go — Read go.mod for: github.com/gin-gonic/gin (Gin), github.com/labstack/echo (Echo), github.com/gofiber/fiber (Fiber).

If no framework detected, set to null.

1.3 Package Manager (Node.js only)

Lock File	Package Manager
pnpm-lock.yaml	pnpm
yarn.lock	yarn
bun.lockb	bun
package-lock.json	npm

Default to npm if no lock file found. For non-Node.js, set to null.

1.4 Test Runner

Node.js/TypeScript (first match wins):

1. Glob for vitest.config.* or vitest in devDependencies -> vitest
2. Glob for jest.config.* or jest in devDependencies -> jest
3. mocha in devDependencies -> mocha

Python: Check for [tool.pytest] in pyproject.toml or pytest in dependencies -> pytest (default for Python).

Go: go test (built-in). Rust: cargo test (built-in). Java/Maven: mvn test. Java/Gradle: gradle test.

1.5 Linter

Marker	Linter
.eslintrc* OR eslint.config.* OR eslint in devDependencies	eslint
biome.json OR @biomejs/biome in devDependencies	biome
[tool.ruff] in pyproject.toml OR ruff.toml	ruff
.golangci.yml OR .golangci.yaml	golangci-lint
.clippy.toml or clippy in Cargo.toml	clippy

1.6 Formatter

Marker	Formatter
.prettierrc* OR prettier in devDependencies	prettier
biome.json (also formats)	biome
black in Python deps	black
[tool.ruff.format] in pyproject.toml	ruff format
rustfmt.toml OR .rustfmt.toml	rustfmt

If biome detected as both linter and formatter, report once as "Biome (lint + format)".

1.7 Type Checker

Marker	Type Checker
tsconfig.json	tsc
mypy in Python deps OR [tool.mypy] in pyproject.toml	mypy
pyright in Python deps OR pyrightconfig.json	pyright

Go (go vet) and Rust (cargo check) have built-in type checking — note but do not list separately.

1.8 CI Detection

Marker	CI System
.github/workflows/*.yml	GitHub Actions
.gitlab-ci.yml	GitLab CI
Jenkinsfile	Jenkins
.circleci/config.yml	CircleCI

1.9 Git Hooks Detection

Marker	Hook System
.husky/	Husky
.pre-commit-config.yaml	pre-commit
.lefthook.yml	Lefthook

1.10 Present Results

After all detection, present findings:

I detected the following about your project:

  Language:        {language}
  Framework:       {framework or "None detected"}
  Package manager: {package_manager or "N/A"}
  Test runner:     {test_runner or "None detected"}
  Linter:          {linter or "None detected"}
  Formatter:       {formatter or "None detected"}
  Type checker:    {type_checker or "None detected"}
  CI:              {ci or "None detected"}
  Git hooks:       {git_hooks or "None detected"}

---

Phase 2: Interactive Questions

Use AskUserQuestion to ask ONLY questions relevant based on detection. 3-5 questions maximum.

Always ask:

1. Coverage threshold — "What test coverage threshold do you want to enforce?" Options: "100% (Recommended)" / "80%" / "60%" / "Custom"

Ask only if relevant:

2. External AI tools — Ask only for non-trivial projects: "Set up external AI tools (Codex/Gemini) for cost savings on implementation?" Options: "Yes" / "No"

3. Visual review — Ask only if a web framework was detected (Next.js, Nuxt, React, Vue, Angular, SvelteKit, Django, Flask): "Enable visual screenshot review for UI changes?" Options: "Yes" / "No"

4. CI pipeline — Ask only if NO CI detected: "Create a GitHub Actions CI pipeline?" Options: "Yes (Recommended)" / "No"

5. Git hooks — Ask only if NO hooks detected: "Set up git hooks for pre-push quality checks?" Options: "Yes (Recommended)" / "No"

---

Phase 3: Write Required Files

Step 1: Run the mandatory files script

This is the FIRST thing to do after Phase 2. Determine the coverage command, then run:

bash "${CLAUDE_PLUGIN_ROOT}/lib/setup-mandatory-files.sh" "$(pwd)" <threshold> "<coverage-command>"

Example for Python with pytest at 100%:

bash "${CLAUDE_PLUGIN_ROOT}/lib/setup-mandatory-files.sh" "$(pwd)" 100 "pytest --cov --cov-fail-under=100"

Check the JSON output. If "status": "ok", the 3 mandatory files are done. Report to the user what was created.

If the script fails or is not found, write the files manually (see CRITICAL-REQUIREMENTS above for what they are).

Step 2: Customize CLAUDE.md TODO sections

If CLAUDE.md was newly written (not appended), use Edit to replace the TODO placeholders:

• Replace npm test / npm run test:coverage with the detected test/coverage commands
• Replace TypeScript strict mode / ESLint + Prettier with the detected language tools
• Remove the <!-- TODO: ... --> comment lines

If CLAUDE.md was appended to (existing file), this step is not needed.

---

Step 3: Additional files

Knowledge Base

Read each file from ./knowledge/:

• patterns.jsonl, gotchas.jsonl, decisions.jsonl, api-behaviors.jsonl, codebase-facts.jsonl, anti-patterns.jsonl, facts.jsonl

Write them to .beads/knowledge/ in the project. Skip any that already exist.

Shell Utilities

Read each file from ./bin/:

• estimate-cost.sh, external-tools-verify.sh, pr-comments-check.sh, pr-comments-filter.sh

Write them to bin/ in the project. Make executable with chmod +x. Skip any that already exist.

TypeScript Scripts

Read each file from ./scripts/:

• beads-self-reflect.ts, beads-fetch-pr-comments.ts, beads-fetch-conversation-history.ts

Write them to scripts/ in the project. Skip any that already exist.

Node.js dependency warning: If Node.js was NOT detected as the project language, print:

"Note: scripts/*.ts require Node.js (npx tsx) to run. Some advanced features (self-reflect, PR comment fetching) will work once Node.js is available. Core metaswarm functionality does not require Node.js."

Conditional Files

Condition	Source	Destination
User chose YES for CI	./templates/ci.yml	.github/workflows/ci.yml
User chose YES for git hooks AND Husky detected or Node.js project	./templates/pre-push	.husky/pre-push (chmod +x)
User chose YES for external tools	./templates/external-tools.yaml	.metaswarm/external-tools.yaml
Always	./templates/.env.example	.env.example
Always	./templates/SERVICE-INVENTORY.md	SERVICE-INVENTORY.md
Always	./templates/gitignore	Merge into existing .gitignore (append missing entries, never duplicate)

For .gitignore, read the existing file (if any), then append language-specific entries that are not already present. Always ensure .env, .DS_Store, and *.log are included.

---

Phase 4: Profile Creation

Write .metaswarm/project-profile.json with all detection results and user choices:

{
  "metaswarm_version": "1.0.0",
  "distribution": "plugin",
  "installed_at": "{current ISO 8601 timestamp}",
  "updated_at": "{current ISO 8601 timestamp}",
  "detection": {
    "language": "{detected language}",
    "framework": "{detected framework or null}",
    "test_runner": "{detected test runner}",
    "linter": "{detected linter or null}",
    "formatter": "{detected formatter or null}",
    "package_manager": "{detected package manager or null}",
    "type_checker": "{detected type checker or null}",
    "ci": "{detected CI system or null}",
    "git_hooks": "{detected hook system or null}"
  },
  "choices": {
    "coverage_threshold": 100,
    "external_tools": false,
    "visual_review": false,
    "ci_pipeline": false,
    "git_hooks": false
  },
  "commands": {
    "test": "{resolved test command}",
    "coverage": "{resolved coverage command}",
    "lint": "{resolved lint command or null}",
    "typecheck": "{resolved typecheck command or null}",
    "format_check": "{resolved format check command or null}"
  }
}

Fill all values from detection and user answers. Use null for anything not detected.

Command resolution reference:

Test Runner	Pkg Mgr	Test Command	Coverage Command
vitest	pnpm	pnpm vitest run	pnpm vitest run --coverage
vitest	npm	npx vitest run	npx vitest run --coverage
vitest	yarn	yarn vitest run	yarn vitest run --coverage
jest	pnpm	pnpm jest	pnpm jest --coverage
jest	npm	npx jest	npx jest --coverage

pytest	--	pytest	pytest --cov --cov-fail-under={threshold}
go test	--	go test ./...	go test -coverprofile=coverage.out ./...
cargo test	--	cargo test	cargo tarpaulin --fail-under {threshold}
mvn test	--	mvn test	mvn test jacoco:report
gradle test	--	gradle test	gradle test jacocoTestReport

---

Phase 5: Post-Setup Actions

5.1 External Tools (if enabled)

1. Check if Codex and Gemini CLIs are installed via Bash (command -v codex, command -v gemini)
2. For tools not installed, tell the user how to install them
3. For installed tools, verify with --version
4. Update .metaswarm/external-tools.yaml — set enabled: true for installed tools, enabled: false for missing ones

5.2 Visual Review (if enabled)

1. Run npx playwright install chromium via Bash
2. Report success or failure

5.3 Git Hooks (if enabled)

Node.js/TypeScript: Install Husky if not present, run npx husky init, write pre-push hook. Python: Suggest pip install pre-commit and offer to create .pre-commit-config.yaml. Other: Suggest appropriate hook tools for the ecosystem.

---

Phase 6: Summary

Present a final summary:

Setup complete! Here's what was configured:

  Project:         {name}
  Language:        {language}
  Framework:       {framework or "None"}
  Test runner:     {test_runner} -> `{test command}`
  Coverage:        {threshold}% -> `{coverage command}`
  Linter:          {linter or "None"}
  Formatter:       {formatter or "None"}
  CI:              {ci or "None"}
  Git hooks:       {hooks or "None"}
  External tools:  {Enabled/Disabled}
  Visual review:   {Enabled/Disabled}

Mandatory files:
  ✔ CLAUDE.md          — {written new / appended metaswarm section / already had it}
  ✔ .coverage-thresholds.json — {threshold}% coverage, enforcement: `{command}`
  ✔ .claude/commands/   — 6 shims: start-task, prime, review-design, self-reflect, pr-shepherd, brainstorm

Other files written:
  {list every other file written or modified with its path}

You're all set! Run /start-task to begin working.

Command naming: When recommending commands to the user, always use the short shim names (/start-task, /prime, /brainstorm, etc.), NOT the namespaced plugin names (/metaswarm:start-task). The shims you just created in .claude/commands/ make the short names work. The short names are easier to type and remember.

Offer 1-2 relevant tips based on configuration:

• If external tools enabled: "Use /external-tools-health to check tool status."
• If no CI set up: "Consider adding CI later -- metaswarm includes a template at ./templates/ci.yml."
• If visual review enabled: "The visual review skill will screenshot your app during development."

---

Missing Setup Auto-Detection

If /start-task is invoked and .metaswarm/project-profile.json does not exist, the start skill should auto-route here. This skill will run the full setup flow, then hand back to /start-task to continue with the user's original request.

---

Error Handling

• If any Bash command fails, report the error and offer to skip that step or retry.
• If a file cannot be read, note it and continue with other detection.
• If AskUserQuestion is dismissed, use defaults: 100% coverage, no external tools, no visual review.
• Never leave the project half-configured. The pre-flight check allows re-running setup to completion.
• All template paths are hardcoded in this skill. Never construct file paths from user-provided input.

---

Final Verification (run this before declaring setup complete)

Before saying "setup complete", run this Bash command to verify the 3 mandatory files:

echo "CLAUDE.md:"; grep -c "metaswarm" CLAUDE.md 2>/dev/null || echo "MISSING"; echo "coverage:"; ls .coverage-thresholds.json 2>/dev/null || echo "MISSING"; echo "shims:"; ls .claude/commands/start-task.md .claude/commands/prime.md .claude/commands/brainstorm.md 2>/dev/null || echo "MISSING"

If any output says "MISSING", go back and run the setup-mandatory-files.sh script or create the files manually. Do NOT declare success with missing files.

When reporting available commands to the user, use the short names (/start-task, /prime, /brainstorm, etc.) — NOT the namespaced names (/metaswarm:start-task). The command shims make the short names work. Do NOT recommend commands that don't exist (e.g., /metaswarm:start, /metaswarm:status, /metaswarm:architect-agent).
