Module a2a 

A2A discovery surface: the well-known catalog card and per-alias agent cards.

Structs

AgentCapabilities

A2A capability flags. All optional; only Some values serialize.

AgentCard

A2A AgentCard. Serializes to the protobuf-JSON wire shape. Used for both the per-alias spec-conforming cards and the ZeroClaw discovery catalog card (the catalog uses skills: [] and a synthetic catalog interface).

AgentInterface

A single declared transport interface (A2A AgentInterface). The first entry of supportedInterfaces is the preferred one.

AgentSkill

A2A AgentSkill. id/name/description/tags are spec-required.

Functions

a2a_routes

a2a_task_route

build_agent_card

Build a spec-conforming per-alias agent card, or None when the alias is unknown or not published. Skills resolve from the alias’s bundles and narrow through exposed_skills.

build_catalog_card

Build the ZeroClaw discovery catalog card served at the origin root. Lists every published alias as a skill-less entry pointing at its per-alias card and endpoint. This is a catalog, not a runnable agent: it advertises the catalog interface and carries no skills of its own.
