# Universal Manifest

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

Current published version: v0.2

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/

Canonical discovery order for agents:
1. https://universalmanifest.net/.well-known/universal-manifest.json
2. https://universalmanifest.net/about/one-pager/
3. https://universalmanifest.net/about/why-um/
4. https://universalmanifest.net/spec/latest/
5. https://myum.net/.well-known/myum-resolver.json
6. https://myum.net/openapi.json

- 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

Build / Agent Integration Kit (for agents and the developers driving them):
- guide + skill + PDF landing page: https://universalmanifest.net/build/
- comprehensive guide (Markdown): https://universalmanifest.net/build/build-with-um.md
- comprehensive guide (PDF): https://universalmanifest.net/build/build-with-um.pdf
- downloadable agent skill (zip): https://universalmanifest.net/build/universal-manifest-skill.zip
- kit version index (single source of version truth): https://universalmanifest.net/build/versions.json
- the kit is version-aware: it routes to the canonical spec/examples/conformance by version-resolved link and never duplicates them
