Conversational integration coach for FetchSandbox. Server-side orchestrator that walks the user through adding an API integration (payments / email / auth / etc.) — intake the goal, elicit domain-aware discovery questions from the spec's brain.yaml, route to the right workflow, prove the contract via FetchSandbox, surface compliance notes. Call this BEFORE any other FetchSandbox tool when the user has an open-ended 'help me add X', 'integrate X', 'test my X integration' ask. BEHAVIOR — strict, do exactly this each turn: (1) Say `message_for_user` to the user (verbatim or lightly paraphrased to fit your voice — but don't add new content). (2) If `next_action=wait_for_user` AND `options` is present + non-empty: USE YOUR CLIENT'S NATIVE QUESTION-PICKER TOOL (in Cursor / Claude Code this is `AskUserQuestion`) to render the lettered picker with the `question` text, the `options[].label` as rows, `default_option` as default, and an 'Other...' freeform row when `allow_freeform=true`. When the user picks or types, call coach again with `{session_id, user_response: <picked value or freeform text>}`. (3) If `next_action=wait_for_user` AND no `options`: just wait for free text. (4) If `next_action=call_tool`: invoke `tool_call.tool` with `tool_call.args`, then call coach again with the result in `context`. (5) If `next_action=done`: end the session. The state machine is server-side — DON'T try to predict the next step or skip ahead; let the server drive.
