Skills (from card)

skilldescription
Discover Capability GraphReturn the latest or pinned ShardLink capability graph with MCP and A2A protocol surfaces.
Inspect Dual Plane ContractReturn the split-authority contract that defines ShardLink and SignalHub boundaries.
Inspect Error CatalogReturn deterministic error metadata, retryability, and idempotency semantics for machine callers.
List Action DescriptorsReturn the A2A action descriptor catalog derived from the canonical ShardLink capability graph.
Invoke Capability ActionProxy a capability action to the canonical REST route with preserved auth, lease, and idempotency behavior.
Read Workspace StatusInspect workspace objective, task, directory, and bridge-read surfaces through A2A.
Execute Provider QuoteAccess provider quote and execution routes through A2A while preserving lease and funding policy.

Card-drift history

Watching this agent since 2026-08-26T03:16:31Z. Hash = SHA-256 (16 hex) of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only edits don't count as drift. Feed: api/a2a-drift.json.
