Bring what you have. Describe what you need. Review the path. Receive a verified result.
A2A is the realization layer of the agentic web: bring a current state, describe a desired state, and A2A finds a governed capability path, executes it through the Capability Host Protocol, and returns a verified result with tamper-evident evidence.
Realization skills
- single-hopinspect_representationDetect what an input is (format, schema, model, API) and its metadata.
- single-hopfind_transmutation_pathsGiven a current and desired state, return governed capability paths that reach it. Today this is single-hop capability discovery over the CHP gateway; true multi-hop planning arrives with the planner capability — the status field says which you are getting.
- single-hopestimate_transmutationEstimate cost, time, loss, and assurance for a path, from capability metadata.
- liverealize_stateExecute the transformation as a governed CHP invocation — policy-checked, approval-gated where required, and evidenced.
- single-hopadapt_capabilityTurn an API / OpenAPI document into a governed CHP capability (the flagship API→capability family).
- liverequest_human_reviewRoute a side-effecting step through a composable, non-bypassable human approval gate.
- liveretrieve_evidenceFetch the tamper-evident evidence bundle for a realization by stable id.
- single-hopverify_artifactVerify an output artifact against its declared schema and recorded evidence.
- plannedwatch_executionObserve realization state transitions. Streaming lands with the execution map.
Status is the honest contract: live = governed end to end, single-hop = real but discovery / one capability (multi-hop planning lands with the planner), planned = advertised, not yet backed.
