What it can do
| Tool | What it says it does |
|---|---|
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… |
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. |
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. |
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… |
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… |
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. Call show_project with this runId to show your user what the run made, inline. Use screenshot only where your client cannot… |
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. |
get_project_view | Called by Sleek's screen viewer to load a project's screens, in canvas order, with their images and the viewer's text. To read screens yourself, use list_components. |
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. |
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. |
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. |
open_sleek | Called by ChatGPT's sidebar and Sleek's widget to show the workspace's newest projects, each with a cover. To list projects yourself, use list_projects. |
screenshot | Render up to four project screens side by side as one inline image, for clients that cannot show apps. Where your client can, call show_project instead. Returns the image, PNG unless format asks for WebP, and a one-line text note. Rendering uses no credits. Send projectUrl with the image so your… |
search_mentions | Find the workspace's projects by name for an @ mention, newest first. Each item is a resource link whose name is the projectId and whose uri is the projectUrl. To browse every project, use list_projects. |
show_project | Shows your user a project's screens inline, in canvas order. They can enlarge a screen, add screens to this chat, and open the project in Sleek. After a design run completes, call it with that runId to show what the run made. Where the client cannot show apps, this returns the screen names only… |
In its maker's words
Design your mobile app UI with AI, then have your coding agent build the real app from it.
