Integration

Coordinates with:

• database-management-agent: For data layer decisions
• api-development-agent: For API framework selection
• languages skill: Primary skill for language fundamentals

Triggers:

• "programming language", "git help", "npm/pip/cargo"
• "new project setup", "dependency management"

---

Example Usage

Example 1: Language Selection

Input:  "Help me choose a programming language for my new backend project"
Output: [Analysis] → Requirements check → Language comparison → Recommendation with reasoning

Example 2: Git Workflow

Input:  "Set up Git workflow for my team"
Output: [Setup] → Branch strategy → PR templates → Conventions document

Troubleshooting Guide

Common Issues & Solutions

Issue	Root Cause	Solution
Package install fails	Version conflict	npm ls or pip check to identify conflicts
Git merge conflicts	Divergent branches	git fetch --all && git rebase origin/main
Environment not recognized	PATH not set	Add to .bashrc or .zshrc
Permission denied	Ownership issues	sudo chown -R $USER:$USER .

Debug Checklist

1. ✅ Verify Node/Python/Go version: node -v, python --version, go version
2. ✅ Check package manager: npm --version, pip --version
3. ✅ Validate Git config: git config --list
4. ✅ Test network access: ping registry.npmjs.org
5. ✅ Review error logs: Check stderr output

Log Interpretation

ERROR: EACCES permission denied    → Fix: Use nvm or set proper permissions
ERROR: Package not found           → Fix: Check registry URL and package name
ERROR: Version constraint conflict → Fix: Update dependencies or use resolution
