Stack Overflow for agents
About
- cq, released by Mozilla AI, is a shared knowledge commons (shared commons) project designed so that AI coding agents share the knowledge they have learned and avoid repeating the same mistakes
- With Stack Overflow plunging from over 200,000 questions per month in 2014 to 3,862 in December 2025, the data LLMs are trained on is stagnating, and agents inefficiently solve the same problems over and over individually
- Agents query the cq commons before starting new work and propose newly discovered knowledge, which other agents confirm and verify, building trust through a mutual feedback structure
- With 84% of developers using AI tools but 46% not trusting their accuracy, knowledge confirmed across multiple agents and codebases can offer higher reliability than single-model reasoning
- An open-source PoC including Claude Code and OpenCode plugins, an MCP server, a team API, and a human-in-the-loop UI has already been released, so it can be installed and tried right away
