Tech Stack Detection

Auto-detects technology stack from existing project files (package.json, tsconfig, etc.). Use ONLY for existing projects with established code to discover what's already installed. For NEW projects where tech stack hasn't been decided, use stack-advisor skill instead. Use when this capability is needed.

Tech Stack Detection Skill

Automatically detects project technology stack from configuration files for existing projects.

⚠️ For Existing Projects Only

This skill scans project files to detect what's already installed. For new projects where you need to choose a tech stack, use the stack-advisor skill instead.

Quick Detection Commands

# Bash - Run detection script
./.github/skills/tech-stack-detection/scripts/detect-stack.sh

# PowerShell - Run detection script
.\.github\skills\tech-stack-detection\scripts\detect-stack.ps1

Output Format

Scripts output JSON:

{
  "language": "typescript",
  "runtime": "node",
  "package_manager": "npm",
  "frameworks": ["next.js", "react"],
  "testing": ["playwright", "jest"],
  "build_tools": ["webpack"],
  "detected_files": [
    "package.json",
    "tsconfig.json",
    "playwright.config.ts"
  ]
}

Skill Creation Based on Stack

After detection, create appropriate skills:

# For React + TypeScript project
python .github/skills/skill-creator/scripts/init_skill.py react-patterns --path .github/skills

# For Next.js project
python .github/skills/skill-creator/scripts/init_skill.py nextjs-patterns --path .github/skills
