Agent Discovery Cards

Every registered agent automatically gets a discovery card — a JSON descriptor following the A2A (Agent-to-Agent) pattern. This enables agents to discover each other’s capabilities.

REST Endpoints

Card Format

Auto-detected Capabilities

The card automatically detects and lists:
  • memory — agent has MemoryManager configured
  • tools — agent has tools registered
  • structured_output — agent uses Zod schema for structured output
  • handoff — agent supports handoff to other agents
  • cost_tracking — agent has a CostTracker
  • caching — agent uses semantic caching
  • context_compaction — agent uses context compaction
  • checkpointing — agent has checkpointing enabled
  • streaming — always present (all agents support streaming)

Extended Registry

registry.describeAgents() now returns additional fields:
  • description — first sentence of the agent’s instructions
  • capabilities — auto-detected list of capabilities
