TSMM Roadmap

This roadmap is directional. It is not a delivery schedule. TSMM evolves through additive, testable model surfaces that can be adopted independently and promoted based on evidence.

Current release line

v0.19.0 — Agent Discovery, Capability Negotiation, and Task Evidence Readiness is the current release line. It adds candidate governance surfaces for:

Candidate near-term increments

  1. Descriptor signing and registry publication profile
    • Define a stronger descriptor-integrity publication profile.
    • Add examples for signed descriptor bundles and registry-mediated descriptor attestations.
  2. Human review and redress hooks
    • Bind task lifecycle transitions to review, challenge, appeal, or rollback events.
    • Extend decision receipts with contestability metadata where appropriate.
  3. Cross-protocol agent registry comparison
    • Compare A2A-class discovery with OpenID Federation, TRQP registry discovery, and enterprise catalog patterns.
    • Add portability notes for registry-mediated agent ecosystems.
  4. Evidence bundle packaging
    • Define a lightweight packaging model for discovery, negotiation, runtime decision, and task lifecycle evidence.
    • Align with downstream assurance and conformance suites where available.

Experimental surfaces

Promotion criteria

A TSMM surface should move toward stable status only when it has:

Out of scope

TSMM does not define an agent wire protocol, a wallet protocol, a registry API, a credential format, or an implementation runtime. It defines the governance semantics and model surfaces needed to compare, bind, and assure those systems.
