list_projects | List the workspace's projects, newest first. Each project holds one app's screens, theme, and design chat. Check here before create_project to avoid duplicates. |
create_project | Create an empty project, then call design and screenshot. Creation is free and instant. Only design runs spend credits. Share projectUrl so your user can watch and edit the designs. |
get_project | Fetch a project and its projectUrl. Use it to confirm the project exists and share the URL with your user. Use list_components to see its screens. |
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. Never delete projects to tidy up on your own initiative. |
list_components | List a project's screen names and active version numbers without generated HTML. Pass each item's screenId to design. Pass its id as componentId to get_component or in componentIds to screenshot. Use get_component only when you need a screen's code. |
get_component | Fetch a screen's generated HTML. Returns 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. |
list_references | List curated app styles and their preview images. When your user asks for a look such as Airbnb, brutalist, or dark fintech, pass the closest reference's id as referenceId to design. Without a reference, the agent picks a style. |
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 scre |
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. Share projectUrl and call screenshot. On 'failed', read data.error.message and send your user to data.error.url if present. A |
cancel_design_run | Ask a design run to stop, for example when the brief was wrong. A queued run never starts. A running run stops at its next step and stays 'running' until it settles. A run cut short settles as 'failed' with error code 'cancelled', or 'execution_failed' if saving its changes failed. It keeps any scre |
screenshot | Render up to four project screens as one inline image, after a design run completes. Rendering is free. Send projectUrl with the image so your user can open and edit the designs. |
