Key Points

  • Caliber is an open-source CLI that automatically generates AI coding-agent context files (e.g., Claude/Cursor rules) from a project’s actual codebase to avoid manual setup.
  • It detects the tech stack, naming conventions, and architecture, then writes tailored context files that better reflect the current state of the repository.
  • Caliber keeps context synchronized by using git hooks so generated documentation doesn’t go stale as the code changes.
  • The tool supports Claude Code, Cursor, and OpenAI Codex, and can auto-discover/configure MCP servers for agentic workflows.
  • The project is already seeing rapid community traction (250 GitHub stars, 90 PRs merged in ~3 weeks) and invites contributions across open issues.

hey everyone. been lurking here for a while and wanted to share something we been building.

the problem: ai coding agents are only as good as the context u give them. but writing CLAUDE.md, cursor rules, AGENTS.md for every project by hand is a massive pain. and even if u do write them, they go stale the moment ur codebase changes.

we built Caliber to fix this. its an open source CLI that:

  1. scans ur actual codebase

  2. figures out ur stack, naming conventions, architecture automatically

  3. writes proper context files tailored to ur real project

  4. keeps them in sync via git hooks so they never go stale

works for Claude Code, Cursor and OpenAI Codex. also auto discovers and configures MCP servers which is huge for agentic workflows.

just hit 250 github stars and 90 PRs merged in about 3 weeks. way more traction than we expected, tons of devs contributing skills for different frameworks.

if u use AI coding tools this thing will genuinely save u a lot of setup time. completely free and open source MIT.
