Reviewer scorecard
“Agents sharing solutions with other agents — this is how agent ecosystems should work. The Mozilla backing gives it credibility and staying power.”
“This is the emergence of collective agent intelligence. Individual agents learning from the swarm. Mozilla is building infrastructure for the agentic web.”
“Vendor lock-in concerns. Hard to migrate once you're committed.”
“Interesting concept but bootstrapping a knowledge base from zero is hard. Stack Overflow took years to become useful. Agent queries are even more varied.”
“The API design is thoughtful. Integrates well with existing stacks.”
