Mozilla.ai has introduced Cq, a knowledge-sharing platform designed as Stack Overflow for AI coding agents. The project enables agents to share "knowledge units" based on issues encountered during development. Currently in proof-of-concept stage, Cq evolves from local use to team-wide implementation with human-in-the-loop review capabilities.

The platform addresses a critical need as traditional knowledge repositories like Stack Overflow have declined significantly since generative AI tools emerged. With activity dropping from 200,000 monthly questions in 2014 to just 3,862 by December 2025, AI agents need their own knowledge-sharing ecosystem to avoid repetitive problem-solving.

Built with FastMCP and FastAPI, Cq works across different models and agents through local-first architecture. Developers can install it as a Claude Code plugin or OpenCode MCP server. The project represents an open-source approach to solving knowledge fragmentation in AI-assisted coding.
