# Universal Manifest

Universal Manifest (UM) is a portable JSON-LD document format for sharing identity, credentials, preferences, pointers, and consent between systems.

Primary hosts:
- standards, docs, discovery, and tooling: https://universalmanifest.net
- runtime UMID resolver: https://myum.net

Public entry split:
- landing page: https://universalmanifest.net/
- curated docs entry: https://universalmanifest.net/docs/

- https://universalmanifest.net/workbench/
- https://universalmanifest.net/resolver/

Interaction model:
- universalmanifest.net is a read-mostly standards and tooling surface
- myum.net is a read-only resolver runtime
- these hosts do not currently expose a public A2A task lifecycle, public write API, or public MCP server
- public skill.md is intentionally deferred; llms.txt plus the well-known descriptors are the canonical agent onboarding path
