Skills
create_project

Creates a new Stitch project. A project is a container for UI designs and frontend code.

get_project

Retrieves the details of a specific Stitch project using its project name.

list_projects

Lists all Stitch projects accessible to the user. By default, it lists projects owned by the user.

list_screens

Lists all screens within a given Stitch project.

get_screen

Retrieves the details of a specific screen within a project.

generate_screen_from_text

Generates a new screen within a project from a text prompt. **Instructions for Tool Call:** * This action can take a few minutes to complete. Please be patient. DO NOT RETRY. * If the tool fails with a timeout, don't retry. Instead, try to get the screen with `get_screen` method every 30 seconds for up to 10 times before giving up. * If the tool call fails due to connection error, the generation process may still succeed. Please try to get the screen with `get_screen` method later. **Output:** * **`output_components`**: If `output_components` contains text, return it to the user. If `output_components` contains suggestions (e.g. "Yes, make them all"), present these suggestions to the user. If the user accepts one of the suggestions, call `generate_screen_from_text` again with `prompt` set to the accepted suggestion.

edit_screens

Edits existing screens within a project using a text prompt. **Instructions for Tool Call:** * This action can take a few minutes to complete. Please be patient. DO NOT RETRY. * If the tool call fails due to connection error, the process may still succeed.

generate_variants

Generates variants of existing screens within a project using a text prompt. **Instructions for Tool Call:** * If the tool fails with a timeout, don't retry. Instead, try to get the screen with `get_screen` method every 30 seconds for up to 10 times before giving up.

upload_design_md

Uploads DESIGN.md to a Stitch project. Use this tool when the user wants to create a design system from a DESIGN.md file. **Instructions for Tool Call:** * Call `create_design_system_from_design_md` tool immediately after this tool to create the design system from the uploaded DESIGN.md, and display the design system in the UI.

create_design_system

Creates a new design system for a project. Use this tool when the user wants to set or update the overall visual theme, style, or branding of the application. This includes configuring: - Color Palette: Presets, custom primary colors, and saturation levels. - Typography: Font families (e.g., Inter, Roboto, etc.). - Shape: Corner roundness for UI elements. - Appearance: Light and dark mode background colors. - Design MD: Free-form design instructions in markdown. This tool establishes the foundational design tokens that apply across all screens in the project. **Instructions for Tool Call:** * Call `update_design_system` tool immediately after this tool to apply the design system to the project, and display the design system in the UI.

create_design_system_from_design_md

Creates a design system for a project, with user uploaded DESIGN.md file, and displays the design system in the UI. **Instructions for Tool Call:** * Should call `upload_design_md` tool first to upload DESIGN.md to a Stitch project.

update_design_system

Updates a design system for a project. Use this tool when the user wants to change the overall visual theme, style, or branding of the application. This includes configuring: - Color Palette: Presets, custom primary colors, and saturation levels. - Typography: Font families (e.g., Inter, Roboto, etc.). - Shape: Corner roundness for UI elements. - Appearance: Light and dark mode background colors. - Design MD: Free-form design instructions in markdown. This tool establishes the foundational design tokens that apply across all screens in the project.

list_design_systems

Lists all design systems for a given project.

apply_design_system

Applies a design system to a list of screens. Use this tool when the user wants to update one or more screens to match the style of a design system. This tool applies the selected design system's foundational design tokens (colors, fonts, shapes, etc.) to the chosen screens, modifying their appearance to align with the design system.
