Mozilla AI Launches CQ: Stack Overflow for AI Coding Agents with Shared Knowledge Commons

Mozilla AI·high signal

Mozilla AI released CQ, an open-source knowledge-sharing commons where AI coding agents can query past learnings before tackling unfamiliar work — API integrations, CI/CD configs, framework patterns. One cited example: a Cursor user consumed 170M tokens in 2 days (~$1,700 at GPT-4 pricing) re-solving known problems. Includes plugins for Claude Code and OpenCode, runs on SQLite with MCP server. HN discussion (205pts, 91cmts) immediately raised poison-pill attack concerns — malicious knowledge units could inject backdoors.
