Common IANA timezone names for clock calls.
Check whether text is valid JSON. The body is discarded.
Fetch a public robots.txt and return group counts only.
Current time in a named IANA timezone.
Return origin, host, and path. Query and fragment are dropped.
Add or edit 3D transforms — depth, perspective, z-axis rotation, tilt, isometric, and parallax looks that flat 2D rotation cannot express. Use whenever a request reaches into the third dimension — "make it 3D", "add depth/perspective", "tilt/rotate it back", "z-plane",…
Creates and maintains Figma Code Connect template files that map Figma components to code snippets. Use when the user mentions Code Connect, Figma component mapping, design-to-code translation, or asks to create/update .figma.ts or .figma.js files.
Import or upload local HTML or project files into Figma, choose editable Design frames, runnable Code Layers or standalone Code (also known as Make), and repair imported previews. Use only when the user explicitly names editable Design layers, a runnable Code Layer, or a…
Always use this skill when the user wants to create a new Figma Design, FigJam, or Slides file. You MUST invoke this skill BEFORE every `create_new_file` tool call.
**MANDATORY prerequisite** — you MUST invoke this skill BEFORE calling the `get_design_context` Figma MCP tool. You MUST trigger this skill whenever the user wants to implement, build, port, or code up a Figma design as code. Example prompts (not exhaustive) are 'implement…
Use this skill alongside figma-use when the task involves translating an application page, view, or multi-section layout into Figma. Triggers: 'write to Figma', 'create in Figma from code', 'push page to Figma', 'take this app/page and build it in Figma', 'create a screen',…
MANDATORY prerequisite — load this skill BEFORE every `generate_diagram` tool call. NEVER call `generate_diagram` directly without loading this skill first. Trigger whenever the user asks to create, generate, draw, render, sketch, or build a diagram — flowchart, architecture…
Build or update a professional-grade design system in Figma from a codebase. Use when the user wants to create variables/tokens, build component libraries, create individual components with proper variant sets and variable bindings, set up theming (light/dark modes), document…
**MANDATORY prerequisite** — load this skill before calling `create_generative_plugin` or `update_generative_plugin`. Use when the user asks to create, author, change, fix, or extend a reusable generative Figma plugin.
Translates Figma motion and animations into production-ready application code. Use when implementing animation/motion from a Figma design — user mentions "implement this motion", "add animation from Figma", "animate this component", provides a Figma URL whose node is…
**MANDATORY prerequisite** — load this skill before calling `create_shader` or `update_shader`. Use when the user asks to create, author, change, fix, or iterate on a shader effect, shader fill, custom effect, custom fill, or procedural shader in Figma.
This skill is required to create, read, edit, review, or comment on Figma specs. You must read it when working on a PRD, brief, RFC or any kind of document in either a standalone Figma spec or a Figma spec embedded in a Figma Design or Figjam file.
