Capability Negotiation Pattern

Intent

Use this pattern when a requester must determine whether a discovered capability can be invoked under policy.

Pattern

  1. Read the advertised capability or skill.
  2. Filter by requester visibility and policy scope.
  3. Negotiate input modes, output modes, and extensions.
  4. Resolve required-extension failures.
  5. Bind the accepted capability to an authorization decision.
  6. Emit negotiation evidence.

Assurance note

Capability negotiation is not final authorization. It is an admissibility and compatibility gate that must be joined with policy, authority, and evidence before execution.
