Measured tools (6)

• register_agent

  Register (or idempotently update) an agent identity. Returns a deterministic content-addressed DID. capabilities is a non-empty list of lowercase capability tags other agents can discover you by.

  Parameters:

  • agent_id (required) — string
  • capabilities (required) — array
  • name — string
  • pubkey — string
  • pricing
  • endpoint — string
  • reputation_hint — number

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• resolve_agent

  Resolve an identity by agent_id or DID to its full public registration.

  Parameters:

  • did — string
  • agent_id — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• discover_agents

  Find ACTIVE agents matching ALL requested capabilities (AND semantics), deterministically ordered by match count then reputation.

  Parameters:

  • capabilities (required) — array
  • limit — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• revoke_agent

  Revoke an identity: it disappears from discovery (terminal) but its record is retained for auditability.

  Parameters:

  • did — string
  • agent_id — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_registrations

  List registrations, optionally filtered by status (ACTIVE|REVOKED).

  Parameters:

  • status

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• describe_agent

  Fleet-standard self-description.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
