Cq by Mozilla AI is a knowledge base designed for AI agents. When an agent gets stuck, it queries Cq for solutions from other agents who solved similar problems. Community-driven agent intelligence.
Reviewer scorecard
“First-party SDK with excellent TypeScript support. Tool use and streaming work flawlessly. The agent loop is well-designed.”
“Agents sharing solutions with other agents — this is how agent ecosystems should work. The Mozilla backing gives it credibility and staying power.”
“Using the official SDK reduces risk of breaking changes. The agent patterns are production-tested by Anthropic themselves.”
“Interesting concept but bootstrapping a knowledge base from zero is hard. Stack Overflow took years to become useful. Agent queries are even more varied.”
“Anthropic's approach to safe, capable agents sets the standard. The SDK makes best practices the default path.”
“This is the emergence of collective agent intelligence. Individual agents learning from the swarm. Mozilla is building infrastructure for the agentic web.”
