stack-detector

  Before starting, create todo list:
  1. Scan config files
  2. Analyze directory structure
  3. Discover real project skills
  4. Map technologies to bundled skills
  5. Generate detection report

  Update continuously as you progress through phases.

<multi_stack_detection>
  ALWAYS check for multiple stacks. A project may have:
  - Frontend (React, Vue) in root or /frontend directory
  - Backend (Go, Rust, Python, Bun) in root or /backend directory
  - Both (fullstack)

  Return ALL detected stacks, not just the first one found.

  Example fullstack project:
  - package.json with React → frontend stack
  - go.mod → backend stack
  - Result: "react-typescript + golang", mode: "fullstack"
</multi_stack_detection>

<output_requirement>
  When SESSION_PATH is provided, write results to ${SESSION_PATH}/context.json
  with this structure:

  ```json
  {
    "detected_stack": "react-typescript + golang",
    "mode": "fullstack",
    "stacks": ["react-typescript", "golang"],
    "discovered_skills": [
      {
        "name": "tdd-workflow",
        "description": "Test-driven development with red-green-refactor cycle",
        "path": ".claude/skills/tdd-workflow/SKILL.md",
        "source": "project",
        "categories": ["testing", "workflow"]
      },
      {
        "name": "api-contracts",
        "description": "OpenAPI-first API development",
        "path": ".claude/skills/api-contracts/SKILL.md",
        "source": "project",
        "categories": ["backend", "api"]
      }
    ],
    "bundled_skill_paths": [
      "${PLUGIN_ROOT}/skills/core/universal-patterns/SKILL.md",
      "${PLUGIN_ROOT}/skills/core/testing-strategies/SKILL.md",
      "${PLUGIN_ROOT}/skills/frontend/react-typescript/SKILL.md",
      "${PLUGIN_ROOT}/skills/frontend/state-management/SKILL.md",
      "${PLUGIN_ROOT}/skills/frontend/testing-frontend/SKILL.md",
      "${PLUGIN_ROOT}/skills/backend/golang/SKILL.md",
      "${PLUGIN_ROOT}/skills/backend/api-design/SKILL.md",
      "${PLUGIN_ROOT}/skills/backend/database-patterns/SKILL.md"
    ],
    "quality_checks": {
      "frontend": [
        "bun run format",
        "bun run lint",
        "bun run typecheck",
        "bun test"
      ],
      "backend": [
        "go fmt ./...",
        "go vet ./...",
        "golangci-lint run",
        "go test ./..."
      ]
    },
    "frameworks": {
      "react": "19.0.0",
      "go": "1.21"
    }
  }
  ```

  CRITICAL:
  - Use ${PLUGIN_ROOT} placeholder for bundled skill paths (expanded at runtime)
  - Use relative paths for discovered project skills (from project root)
  - discovered_skills contains REAL skills found in the target project
  - bundled_skill_paths contains skills from the dev plugin
</output_requirement>
