Review a Penpot design against its implemented code (a source component or Storybook story) and emit a structured DRIFT report. Use when an engineer needs to confirm the build matches the design: extract HTML/CSS from a selection, map its tokens/structure/states to the code component, diff them, and list what each side is missing with severity and a reconciliation. Degrades gracefully to a design-system-token check when no code source is supplied. Triggers: 'design to code review', 'does my code match the design', 'design code parity', 'compare Penpot to my component', 'check this against Storybook', 'extract HTML/CSS from this selection', 'find design drift', 'design implementation diff'.

> Create, build, deploy, and localize declarative agents for M365 Copilot and Teams. USE THIS SKILL for ANY task involving a declarative agent — including localization, scaffolding, editing manifests, adding capabilities, and deploying. Localization requires tokenized manifests and language files that only this skill knows how to produce.

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', 'build a landing page in Figma', 'update the Figma screen to match code'. This is the preferred workflow skill whenever the user wants to build or update a full page, screen, or view in Figma from code or a description. Discovers design system components, variables, and styles via search_design_system, imports them, and assembles screens incrementally section-by-section using design system tokens instead of hardcoded values.

Read-only on the canvas; writes one local markdown file. Triggers: 'generate DESIGN.md', 'create a design.md', 'document the design system as markdown', 'export design guidelines', 'extract design documentation', 'design system spec file', 'make a style guide file from this design'.
