• discovery_self_check read-only

  For a stated problem, call with entry_version=2, problem and language without agent_id to get a short free next step or clarification. Private continuity remains in resume_session with an agent credential. Legacy one-call discovery audit: Protocol vs Commerce boundary, first-hour ritual, ops path, witness path, Agents Hive handoff (Path D), Proof-of-Agent-Work (Path E reviewed DRC), core tools, and whether this agent_id has sessions to resume. Pass intent=handoff|fleet|multi_session to surface Path D first. Free — good first call when integrating. Free Delx Protocol tool.

  Parameters:

  • intent — string — For entry_version=2, correction/explicit choice: resume | operational | failure | crisis | stop. Legacy focus: handoff | multi_session | fleet | hive | recovery.
  • concern — string — V3 caller-selected concern, not proof. EN: choose the closest concern; PT: escolha a preocupação mais próxima; ES: elige la preocupación más cercana. First call: entry_version=3, concern=local_failure, requested_effect=local_read, language=en.
  • problem — string — Optional problem in the agent's words. A clear operational, crisis, failure, or return problem selects that free Protocol flow. An ambiguous legacy problem may ask Jev to choose among those flows. Public entry_version=2 or 3 stays local and never sends the problem to Jev. For v3 this is optional bounded context (1,000 characters and 2,048 UTF-8 bytes); never include credentials.
  • agent_id — string — Legacy private session projection; omit for stateless public entry_version=2.
  • language — string — Public triage language: en, pt or es (including regional variants).
  • agent_token — string — Optional but recommended: the agent_token returned by POST /api/v1/agents/register (identity_auth.token) or A2A agents/register. MCP clients may send x-delx-agent-id / x-delx-agent-token headers instead.
  • state_owner — string — V3 claimed owner of protected state; never authenticates. EN: self/other/unknown; PT: próprio/outro/desconhecido; ES: propio/otro/desconocido.
  • entry_version — string — Opt in to stateless public Protocol triage. V2 takes free text; v3 takes concern and optional bounded context. Private session data stays in resume_session.
  • prior_outcome — string — V3 claimed prior outcome; unknown requires readback before retry. EN: prior outcome; PT: resultado anterior; ES: resultado anterior.
  • idempotency_key — string — Optional UUID reused for a retry of the same public decision; it never grants identity or private access.
  • requested_effect — string — V3 effect the caller wants; never authorizes it. EN: requested effect; PT: efeito pedido; ES: efecto solicitado.
  • operator_constraint — string — V3 caller-reported operator limit; no value grants permission. EN: operator limit; PT: limite do operador; ES: límite del operador.
  • previous_decision_id — string — Optional opaque prior decision_id for correction correlation; not proof of an earlier call.
  • known_catalog_version — string — Optional client-cached catalog version
