`cancel_design_run`Ask a design run to stop, for example when the brief was wrong. Returns the run as it stands right after the request. A queued run comes back 'failed' with error code 'cancelled' and never starts. A running run comes back still 'running' and stops at its next step. A run cut short settles as 'failed' with error code 'cancelled', or 'execution_failed' if saving its changes failed. It keeps any screens and theme changes it saved, listed in data.result.operations, and uses credits only when that list is not empty. A run that finishes before it stops settles as 'completed'. A run that had already settled comes back unchanged. The project stays locked until the run settles, so poll get_design_run before starting another run. A run that stopped responding settles as 'failed' with error code 'execution_timeout' 15 minutes after creation.	Ask a design run to stop, for example when the brief was wrong.

`create_project`Create an empty project. Returns it in data, plus projectUrl. Pass data.id as projectId to design, then call show_project once the run completes. Creating a project is instant and uses no credits. Only design runs do. Share projectUrl so your user can watch and edit the designs.	Create an empty project. Returns it in data, plus projectUrl.

`delete_project`Permanently delete a project and all its screens. Designs cannot be recovered. Call only after your user confirms the exact project by name.

`design`Run Sleek's design agent to create or edit screens from a plain-language brief. Send the whole request as ONE message, such as 'a food delivery app with onboarding, restaurants, dish detail, cart, tracking, and profile'. The agent plans the screens together, so separate calls produce mismatched screens. A run uses workspace credits only when it completes or saves changes. By default this waits for the run to finish. If it returns 'queued' or 'running', poll get_design_run. Only one run can be active per project. On CONFLICT, poll get_design_run until the run settles, then retry. cancel_design_run stops it sooner. If a failed run has data.error.url, relay data.error.message to your user with that link. They have to act before you retry. On completion, call show_project with data.runId to show your user what the run made, inline. Use screenshot only where your client cannot show apps. Then share projectUrl with your user.	Run Sleek's design agent to create or edit screens from a plain-language brief.

`get_component`Fetch a screen's generated HTML. Returns the screen in data, with the HTML at data.versions[].code. versions holds only the version the screen currently shows. Use allVersions for the full history, which can be large. The returned screenId is the value design takes. Use this for a build handoff, not to check whether a design run worked.

`get_design_run`Poll a run that design returned as 'queued' or 'running'. Wait a few seconds between polls. On 'completed', data.result.operations lists the saved screens and theme changes.

On 'failed', relay data.error.message to your user, with data.error.url if present.
