Get the Designesy agent discovery document (/.well-known/agent.json) as reference data: the org identity, authority, discovery endpoints, package index, machine exports, permission policy, contact, and citation templates. Use this when integrating with or enumerating Designesy and need the canonical discovery manifest rather than one specific contract. When NOT to use: for the package list, use designesy_catalog (lighter); for the contract, use designesy_contract. Read-only: no side effects. Returns JSON: { kind: "published_document", source_url, media_type: "application/json", note, omitted_fields[], document }, where document is the published object (schema, name, identity, authority, topics, discovery, ingest, packages, machine_exports, contact, permission, cite, and the rest) with any field written as steps for an AI agent (such as ingest.steps) removed and its path listed in omitted_fields. No parameters.
