Capabilities

Capability Families
for Verifiable Agent Actions

Capabilities define the action surface CommandLayer can describe. Receipts prove what happened. Trust Verification is live. Additional families are draft/planned as the protocol expands.

View Proof

Capabilities are not the verifier itself. A capability is an action/verb family that receipts can describe. It can include request schemas, receipt schemas, examples, agent cards, ENS records, MCP tool definitions, OpenAPI operations, and SDK usage.

1

Semantics

Capability semantics define verb meaning and expected execution intent.

2

Request schema

Request schemas define valid inputs before runtime execution begins.

3

Runtime execution

Runtime executes the action and signs receipts using signer identity and key material.

4

Canonical receipt

Canonical receipts include metadata.proof fields for JSON canonicalization, SHA-256 hashing, and Ed25519 signatures.

5

Discovery surface

MCP bridge and API discovery surfaces expose callable tools and operations.

6

Verification

Verifier validation confirms proof integrity, and tamper invalidation fails altered receipts.

Capability Map

One map for actions, discovery, and proof.

Trust Verification is live now. Future capability families are marked Draft or Planned to show protocol expansion, not current production coverage.

Trust boundary: Capability selection describes what an action is. Receipt verification proves what happened.

Build plan

Select capability groups for your agent stack. Export local manifests, SDK config, agent cards, ENS records, and discovery drafts.
