    capability: &str,
    payload_json: &str,
) -> Result<String, CapabilityPayloadError>
Expand description

Format the per-capability JSON payload into a natural-language task for the selected agent. The contract is per-capability and documented in docs/agent-bundle-spec.md.

This is intentionally NOT a silent fallback. Callers send this JSON from a structured intent definition (Swift @AppIntent parameters → JSON encode); a missing field means the host’s intent shape drifted from the runtime’s expectation, and we’d rather hard-error at the FFI boundary than send raw JSON to a model that will dutifully summarize the JSON itself.
