Where an agent host starts: the contract, the quick reference, the tools, the error table, and the honesty rules.
The one-page reference for driving the CLI from an agent: flags, envelopes, gates, and codes.
Every tool the natural-language agent can call, grouped by what it touches.
What each error code means and the recovery an agent should take.
The promises the CLI keeps about what it did, did not do, and could not verify.
Intent patterns that work well for agents, and the wording that trips the gates.
