  "mechanism": "Macro for {{discover}}({{agent}}). A protocol for agents to advertise their capabilities and discover other agents dynamically. Each agent publishes a capability {{card}} describing what it can do, its input/output schemas, and trust requirements. Agents query a registry (or broadcast) to find collaborators for subtasks. Enables dynamic multi-agent composition without hardcoded agent references. It instantiates the abstract {{discover}} primitive on the {{agent}} type, specifically querying capability registries rather than passive data stores.",
