Open source. Open possibilities.

A community-curated collection of custom agents, instructions, skills, hooks, workflows, and plugins for GitHub Copilot, with a searchable website, Learning Hub, and installable plugin marketplace.

Context Engineering Protocol provides AI coding-agent skills that assemble human-approved, source-attributed context packages — code graphs, requirements, org conventions, and constraints — before generation runs. It detects gaps, conflicts, and staleness across sources, gates output behind explicit human approval, and supports Claude Code, GitHub Copilot, Cursor, and OpenAI Codex.
