|---|---|
| Discover Capability Graph | Return the latest or pinned ShardLink capability graph with MCP and A2A protocol surfaces. |
| Inspect Dual Plane Contract | Return the split-authority contract that defines ShardLink and SignalHub boundaries. |
| Inspect Error Catalog | Return deterministic error metadata, retryability, and idempotency semantics for machine callers. |
| List Action Descriptors | Return the A2A action descriptor catalog derived from the canonical ShardLink capability graph. |
| Invoke Capability Action | Proxy a capability action to the canonical REST route with preserved auth, lease, and idempotency behavior. |
| Read Workspace Status | Inspect workspace objective, task, directory, and bridge-read surfaces through A2A. |
| Execute Provider Quote | Access provider quote and execution routes through A2A while preserving lease and funding policy. |
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:
