cq is an open standard and tooling for shared agent learning: AI coding agents persist, share, and query structured knowledge units so they avoid repeating each other's mistakes. It ships as a CLI that installs an MCP server and skill into hosts like Claude, Codex, Copilot, Cursor, and OpenCode, with Go and Python SDKs.

Use cases

• stop my coding agent from rediscovering the same bugs
• share debugging knowledge between AI agents
• query known pitfalls before an agent retries a task
• propose learnings from an agent session automatically
• install an MCP knowledge server into Claude or Cursor
• build a collective knowledge base of undocumented API behavior

When to choose

• you use AI coding agents and want them to learn from past failures
• you want a shared, queryable knowledge store across multiple agent hosts
• you need an MCP server plus CLI and SDKs for agent knowledge sharing

When to avoid

• you need a stable, production-hardened system (0.x with breaking changes)
• you want fully automatic knowledge capture without human approval
• you don't use MCP-capable or supported coding agents
