What is ContextForge?
ContextForge is a registry-powered CLI for installing AI-agent instruction packs into existing repositories.

The core idea
AI coding agents work best when a repo tells them how to behave. Most repos don't. ContextForge fixes this by fetching curated instruction packs from the official registry and installing them directly into your project.
Packs are fetched at install time from:
Then written under .contextforge/ inside your repo.
What ContextForge is NOT
- Not an MCP gateway
- Not a tool proxy or API gateway
- Not a replacement for skills.sh
- Not a prompt injection framework
ContextForge is a repo-level AI-agent instruction installer. That's the whole product.
What ContextForge helps agents do
- Verify before claiming completion
- Debug systematically — find root causes, not band-aids
- Review code for correctness, security, and performance
- Handle Git operations safely with explicit permission gates
- Manage dependencies carefully
- Follow your framework and stack conventions
- Keep documentation updated as work progresses
