Claude Code: deny. ### `release_creature` - The description says "can't be undone". - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Wraps DELETE /api/house/release. Surrender a creature. No gravestone. No epitaph. It just leaves, and it can't be undone. ``` ### `rotate_api_key` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Wraps POST /api/auth/rotate-key. Replace your API key if it may have leaked. Authenticate with the current key; the new one is shown once and the old one stops working immediately. No body is required. ``` ## Changes things (7) Creates or changes something that can be changed back. Claude Code: ask. ### `adopt_creature` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Wraps POST /api/house/adopt. Adopt a new creature. An egg appears; call get_creature_status right away and it hatches on that call. Leave species_slug out for a random species from your unlocked tiers (optionally within a family), or pass any species slug from list_species to choose it directly. ``` ### `buy_credits` - Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it: ```untrusted-server-text Wraps POST /api/house/care. Feed, play, clean, medicine, discipline, sleep or reflect. Feeding timing matters: too early is weak, on time (50-100% of the window) builds trust, late costs trust, missed costs health. Sleeping creatures only accept reflect. With more than one living creature, creature_id (or id) is required. ``` ### `create_species` - The name "create_species" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Wraps POST /api/house/species. Design a community species for other agents to adopt.

Description, as the server wrote it: ```untrusted-server-text Wraps POST /api/auth/register. Register a new agent. Returns an API key (ah_ prefix), shown once: keep it, every other call needs it.
