name: Project Detection description: Comprehensive tech stack detection, framework identification, dependency analysis, and project.json generation. Use when analyzing project structure, detecting frameworks, identifying dependencies, discovering AI stack components, detecting databases, or when user mentions project detection, tech stack analysis, framework discovery, or project.json generation. allowed-tools:

Project Detection Skill

CRITICAL: The description field above controls when Claude auto-loads this skill.

Overview

Provides comprehensive project analysis capabilities including framework detection, dependency analysis, AI stack identification, database detection, and automatic .claude/project.json generation.

Instructions

Framework Detection

1. Use scripts/detect-frameworks.sh <project-path> to identify all frameworks
2. Detects frontend frameworks: Next.js, React, Vue, Svelte, Angular, Solid.js
3. Detects backend frameworks: FastAPI, Django, Flask, Express, NestJS, Go frameworks, Rust frameworks
4. Identifies meta-frameworks and build tools
5. Returns structured JSON output with versions and confidence scores

Dependency Analysis

1. Use scripts/detect-dependencies.sh <project-path> to analyze all dependencies
2. Scans package.json, requirements.txt, go.mod, Cargo.toml, Gemfile, composer.json
3. Categorizes dependencies: production, development, peer
4. Identifies version ranges and exact versions
5. Detects dependency conflicts and outdated packages

AI Stack Identification

1. Use scripts/detect-ai-stack.sh <project-path> to discover AI components
2. Detects: Vercel AI SDK, Claude Agent SDK, LangChain, Mem0, OpenAI SDK
3. Identifies AI model providers and API integrations
4. Discovers RAG systems and vector databases
5. Finds agent frameworks and orchestration tools

Database Detection

1. Use scripts/detect-database.sh <project-path> to identify databases
2. Detects: Supabase, PostgreSQL, MongoDB, Redis, MySQL, SQLite
3. Identifies ORMs: Prisma, TypeORM, SQLAlchemy, GORM, Diesel
4. Finds connection strings and configuration files
5. Discovers database migration tools

Project.json Generation

1. Use scripts/generate-project-json.sh <project-path> to create complete project.json
2. Aggregates all detection results into structured format
3. Generates .claude/project.json with complete tech stack information
4. Includes framework versions, dependencies, AI stack, databases
5. Adds metadata: language, build tools, test frameworks, deployment targets

Detection Strategies

Frontend Detection

• Check for framework-specific config files (next.config.js, vite.config.ts)
• Scan package.json for framework dependencies
• Identify build tool configurations
• Detect UI component libraries (shadcn, Material-UI, Tailwind UI)

Backend Detection

• Identify web framework imports and decorators
• Scan for framework-specific file structures
• Detect API route patterns
• Find server configuration files

AI Stack Detection

• Search for AI SDK imports and usage
• Identify model provider API keys in env files
• Detect vector database configurations
• Find agent and tool definitions

Database Detection

• Scan for database client imports
• Find ORM schema definitions
• Identify connection string patterns
• Detect migration directories

Output Format

All detection scripts output JSON in this format:

{
  "detected": true,
  "confidence": "high|medium|low",
  "type": "framework|database|ai-stack",
  "name": "Framework Name",
  "version": "1.0.0",
  "files": ["list", "of", "evidence", "files"],
  "metadata": {}
}

Requirements

• Support 30+ frameworks across 8+ languages
• Provide confidence scores for all detections
• Include file paths as evidence
• Generate valid project.json schema
• Handle monorepos and multi-framework projects
• Detect framework versions accurately
• Identify both direct and transitive dependencies

Integration

This skill is used by:

• foundation:init command - Initial project analysis
• foundation:analyze command - Deep project structure analysis
• All code generation skills - Framework-specific code templates
• All deployment commands - Framework-specific deployment configs
