Setup Skill

Setup Skill

Generate CLAUDE.md and a complete .claude/ ecosystem by scanning the user's codebase.

Execution Flow

Run these 9 phases in order. Do NOT skip phases. Do NOT ask unnecessary questions — scan silently and confirm once.

---

Phase 1: Pre-Check

1. Check if CLAUDE.md already exists in the project root.
2. If it exists, ask: "CLAUDE.md already exists. Overwrite, merge, or cancel?"
   • Overwrite — delete existing and generate fresh
   • Merge — keep existing content, add missing sections
   • Cancel — abort setup
3. If .claude/ folder exists, warn: "Existing .claude/ folder found. Existing files will be preserved unless you choose overwrite."
4. If neither exists, proceed silently.

---

Phase 2: Silent Scan

Scan the project WITHOUT asking the user anything. Read these files silently:

Package Detection:

• package.json — dependencies, devDependencies, scripts
• *.csproj — .NET projects, NuGet packages, target framework
• composer.json, Cargo.toml, go.mod — other ecosystems

Framework Detection:

• next.config.* — Next.js (check version in package.json)
• remix.config.* or vite.config.* with @remix-run — Remix
• vite.config.* — Vite (check for React plugin)
• angular.json — Angular

Styling:

• tailwind.config.* or @tailwind in CSS files — Tailwind (check v3 vs v4)
• app.css or globals.css — look for @theme (Tailwind v4) or @apply
• CSS-in-JS patterns in components

Design Tokens:

• @theme block in CSS — extract custom properties (--color-*, --spacing-*, --font-*)
• tailwind.config.js theme.extend — extract token definitions
• CSS custom properties in :root

Backend:

• *.csproj with Microsoft.AspNetCore — ASP.NET Core
• Program.cs, Startup.cs — .NET entry points
• appsettings.json — connection strings, JWT config

Database:

• Microsoft.EntityFrameworkCore in csproj — EF Core
• Dapper in csproj — Dapper
• DbContext files — database models
• Migration folders

Infrastructure:

• Dockerfile, docker-compose.yml
• .github/workflows/ — CI/CD
• fly.toml, vercel.json, render.yaml

Linter:

• biome.json or biome.jsonc — Biome
• .eslintrc* — ESLint
• .prettierrc* — Prettier

i18n:

• next-intl, react-intl, i18next in dependencies
• messages/ or locales/ folders
• [locale] in Next.js app router paths

CMS:

• sanity.config.* or @sanity in dependencies — Sanity
• contentful in dependencies — Contentful
• strapi — Strapi

Auth:

• firebase or firebase-admin in dependencies — Firebase Auth
• next-auth or @auth/core — NextAuth
• JWT patterns in backend (JwtBearer, AddAuthentication)

Use the detection rules from ${CLAUDE_PLUGIN_ROOT}/references/scan-patterns.md for complete patterns.

Build an internal ScanResult object:

{
  frontend: { framework, version, styling, designTokens, linter, i18n, cms, auth },
  backend: { framework, version, database, orm, auth },
  infrastructure: { docker, ci, deploy },
  projectType: "portfolio" | "marketplace" | "saas" | "ecommerce" | "api-only" | "unknown"
}

---

Phase 3: Confirm

Present the scan results to the user in a compact table:

## Detected Stack

| Layer | Technology | Version |
|-------|-----------|---------|
| Frontend | Next.js | 16.x |
| Styling | Tailwind CSS | v4 |
| Language | TypeScript | strict |
| Linter | Biome | 1.x |
| Backend | ASP.NET Core | .NET 10 |
| Database | MSSQL | EF Core + Dapper |
| Auth | JWT | Bearer |
| Deploy | Docker | Fly.io |

**Detected project type:** Portfolio

Is this correct? (yes / edit)

If the user says "edit", let them correct any values. Otherwise proceed.

---

Phase 4: Archetype Matching

1. Load the archetype reference from ${CLAUDE_PLUGIN_ROOT}/references/archetypes/{projectType}.md
2. If projectType is "unknown", ask the user to pick from: Portfolio, Marketplace, SaaS, E-Commerce, API-Only
3. Show the archetype's typical feature set and ask: "This archetype suggests these features. Customize or proceed?"

---

Phase 5: Customize

Present three selection lists. Each item has a checkbox. Pre-select the recommended items based on scan results.

Primitives (from ${CLAUDE_PLUGIN_ROOT}/references/primitives/frontend.md and backend.md):

• Show each primitive with a one-line description
• Pre-check primitives that match detected technologies
• User can add/remove

Agents (from ${CLAUDE_PLUGIN_ROOT}/references/agents/frontend.md and backend.md):

• Show each agent with its role
• Pre-check agents that match the stack
• User can add/remove

Skills (from ${CLAUDE_PLUGIN_ROOT}/references/skills/catalog.md):

• Show each skill with its trigger
• Pre-check skills that match detected technologies
• User can add/remove

Format:

## Select Primitives

- [x] TAILWIND_FIRST — Utility-first CSS, no @apply in components
- [x] TYPESCRIPT_STRICT — Strict mode, no any, explicit return types
- [ ] DESIGN_TOKENS — CSS custom properties from @theme
- [x] GIT_RULES — Conventional commits, branch naming
...

Add or remove? (proceed / edit)

---

Phase 6: Generate

Generate all files using the templates and selections:

1. CLAUDE.md (project root)

• Use template from ${CLAUDE_PLUGIN_ROOT}/templates/claude-md.md
• Fill in all {{PLACEHOLDER}} values from scan results
• Include: project description, tech stack table, design system tokens (if detected), folder structure, primitives list, agents table, coding rules

2. .claude/primitives/ (one file per selected primitive)

• Use content templates from the primitives reference files
• Each file is a .md with the primitive's rules and examples

3. .claude/agents/ (one file per selected agent)

• Use definitions from the agents reference files
• Each file is a .md with the agent's role, capabilities, and constraints

4. .claude/skills/ (one file per selected skill)

• Create SKILL.md in each skill's folder
• Use descriptions from the skills catalog

5. .claude/prompts/ (standard prompts based on stack)

• new-component.md — if React detected
• new-page.md — if React + router detected
• new-hook.md — if React detected
• new-api-endpoint.md — if backend detected
• new-migration.md — if database detected

After generating, show a tree of created files:

Created:
  CLAUDE.md
  .claude/
  ├── primitives/
  │   ├── TAILWIND_FIRST.md
  │   ├── TYPESCRIPT_STRICT.md
  │   └── GIT_RULES.md
  ├── agents/
  │   ├── ui-developer.md
  │   └── code-reviewer.md
  ├── skills/
  │   ├── tailwind-v4/SKILL.md
  │   └── explain-code/SKILL.md
  └── prompts/
      ├── new-component.md
      └── new-page.md

Phase 7: Plugin Recommendations

Based on the project type, recommend companion plugins from ${CLAUDE_PLUGIN_ROOT}/references/plugins.md:

• market-lens — recommend for ALL project types (product thinking applies everywhere)
• cross-lens — recommend for complex projects (marketplace, saas, ecommerce)

Format:

## Recommended Plugins

Based on your project type (Portfolio), these plugins complement Forge:

1. **market-lens** — Audit your product through Kotler's 4 marketing lenses.
   Helps you think about your portfolio as a product, not just a website.
   Install: `/plugin marketplace add shavidze/market-lens`

2. **cross-lens** — Cross-discipline analysis for deeper insights.
   Install: `/plugin marketplace add shavidze/cross-lens`

Install any? (yes, list numbers / skip)

---

Phase 8: Personal References

If the project has any personal configuration or unique patterns not covered by the standard primitives:

1. Scan for unusual folder structures
2. Check for custom scripts in package.json
3. Look for .env.example to understand environment variables
4. Check for monorepo patterns (workspaces, turbo.json, nx.json)

Add a ## Project-Specific Notes section to CLAUDE.md with any findings.

---

Phase 9: Summary

Print a final summary:

## Forge Setup Complete

- Generated: CLAUDE.md + {N} primitives, {N} agents, {N} skills, {N} prompts
- Project type: {archetype}
- Stack: {frontend} + {backend}
- Plugins recommended: {list}

Your Claude Code ecosystem is ready. Run `/forge:plan` to generate development plans.

Error Handling

• If a file cannot be read (permission error), skip it and note in the summary
• If no package.json or *.csproj found, ask the user to describe their stack manually
• If the project is empty (no source files), generate a minimal CLAUDE.md with just the project description
• Never crash — always degrade gracefully and explain what was skipped
