How to read this: tool names here are observed from a live tools/list handshake. The Risk label is a heuristic inferred from the tool name (write/destructive verbs), not from executing the tool — a conservative guess, not a verified capability. We never escalate risk from a description. Found one that's wrong? Tell us — we fix on report.
| Tool | Risk | Side effects | Approval |
|---|---|---|---|
| create_app Create a new application from a natural language prompt. The AI generates a complete web app with pages, components, styling, and data models. Returns a job_id - poll get_job_status to track progress. When the job is done, the app is ready. | write | true | unknown |
| agency_list_clients Agency mode only. List client records and app handoff status for the authenticated agent. | read | false | unknown |
| agency_create_client Agency mode only. Create or update a client record for an account-level agent. This does not create a verified Fine Structure user account and does not transfer ownership. | write | true | unknown |
| email_marketing_create_broadcast Admin only. Create a filtered broadcast campaign, optionally scheduled or sent now. | write | true | unknown |
| agency_create_client_app Agency mode only. Create a new app owned by the agent, start generation, and create a claim link for the client. Ownership transfers only when the invited client logs in with the same email and accepts the claim link. | write | true | unknown |
| agency_create_claim_link Agency mode only. Create a client claim link for an existing app owned by the agent. The client must log in with the invited email before ownership transfers. | write | true | unknown |
| agency_get_claim_status Agency mode only. Inspect one handoff status without exposing the raw claim token. | read | false | unknown |
| update_app Update an existing application with a new prompt. The AI modifies the app based on your instructions. Creates a Saved Version before the update. Returns a job_id - poll get_job_status to track progress. | write | true | unknown |
| publish_app Publish an app - freeze current state and make it live at a URL. Also configures whether the public URL is open, app-login gated, private, or inferred from the app. | write | true | unknown |
