//! Do a mission agent's pinned skills actually reach its prompt?
//!
//! Before this test the honest answer was no, for every skill and every role.
//! The catalogue's only delivery channel was the `clawmates_skills` MCP server,
//! and a mission claw could not reach it: `provision_claw` wrote a constant
//! bundle list, the runtime config defines no such bundle, and mission claws
//! run on `claude_cli`, which is text-only and cannot surface a tool call.
//!
//! So the skills were authored, bound, listed in the boot log as bound — and
//! structurally unreadable. That is why this is a test and not a comment: the
//! failure produced no error anywhere, and every layer reported success.
