Stirling-ToolsSkill

ui-walkthrough

Stirling-Tools/Stirling-PDF/.claude/skills/ui-walkthrough/SKILL.md

Full UI investigation of the current branch's feature. Enumerates every view and state (empty, populated, loading, error, each dialog/menu/panel, responsive breakpoints, light + dark + RTL), captures them with the stubbed Playwright harness, assembles a single-image HTML walkthrough with a global light/dark toggle slider, then runs two review passes: visual/consistency (alignment, spacing, professionalism, dark/light parity, contrast, truncation) and UX/ease-of-use (flow, discoverability, affordances, empty/error states, expectations). Use when asked for a UI walkthrough, screenshot review, design or QA pass, "find anywhere to make it easier/better for users", or before merging frontend work. Pass --fix to auto-apply safe frontend fixes and re-capture; --theme to limit themes; --no-rtl to skip RTL.

Arize-aiSkill

phoenix-storybook

Arize-ai/phoenix/.agents/skills/phoenix-storybook/SKILL.md

Conventions for creating, modifying, and reviewing production-faithful Storybook stories in the Phoenix frontend (js/app/stories, js/app/.storybook). Covers sidebar taxonomy and titles, the tag vocabulary, entry shape, option grids, component audits, overlays, toasts, themes, domain stories, and Storybook configuration. Use whenever touching `.stories.*` or story `.mdx` files, story fixtures, decorators, helpers in `stories/utils`, thumbnails, `.storybook/` configuration, or a frontend change that adds, changes, moves, or removes stories — including small or mechanical story edits and PR reviews that touch stories.
