Use when checking Indian tax bills, verifying tax math, or reviewing Place of Supply rules. Trigger when asked to "validate this GST number", "check invoice tax split", "verify GSTIN checksum", or "reconcile GSTR-2B", even if GST is not explicitly mentioned.

Re-explain something technical for a reader with no technical background, without dropping any technical detail — jargon defined inline, every exact number, path, flag and error string kept verbatim, a worked example with real values where one helps. Use when the user types /explain-tech, or says "explain that again", "break that down", "walk me through it", "ELI5 but don't dumb it down", "what does that actually mean", or asks for an explanation they can hand to someone non-technical — about Claude's own previous output, a file, a diff, a log, an error, a cost or capacity estimate, or a concept.

A skill written the way the whole surface was written before 2026-10-05. The gate must reject it.

Set up or run the token build pipeline — transform the DTCG tokens/*.json (source of truth) into platform artifacts (CSS variables, Tailwind @theme, JS/TS, iOS Asset Catalog, Android, Compose) with Style Dictionary / Tokens Studio / W3C DTCG export. Use when the user wants to generate platform theme files from tokens, wire token CI, or multi-platform token output.

Scaffold a new design-product project that matches the recommended Claude Code layout (the reference structure). Use when starting a fresh product/app that will be built with this design system.

Upgrade an existing website or app to premium quality without breaking functionality — audit the current design, identify generic/AI tells, then apply taste and system rules surgically. Use when the user wants to improve, modernize, polish, or "make better" an existing UI/codebase.

Optimize UI performance against Core Web Vitals — LCP, INP, CLS — with loading/code-split strategy, layout-shift prevention, and animation performance rules. Use when the user wants to improve speed, fix jank or layout shift, hit Web Vitals budgets, or make a UI feel fast on low-end devices.

Map this token system to or from any external design system (Material Design 3, Apple HIG, Fluent, Carbon, Ant, shadcn/ui, Radix, Chakra, Mantine, Bootstrap…) — adopt their look, build on their stack, or migrate between systems. Use when the user mentions interop, migration, or a specific design-system/component-library bridge.

Govern how the design system evolves — SemVer for tokens/components, the contribution workflow, deprecation policy, and change communication. Use when the user wants to add/promote/deprecate a component or token, decide a version bump, set up a contribution process, or keep the system from fragmenting.

Run the one-command quality gate and report the real N/N result. Use before claiming any build/review is done.

Keep Figma and code in sync — map the 3-tier DTCG tokens to Figma Variables (collections + modes), sync in either direction, use the Figma MCP when connected, and verify component parity (variants/states). Use when the user wants to push tokens/components to Figma, pull a design into code, set up token↔Variable sync, or check design-code drift.

Generate, extend, or audit design tokens in DTCG format with the 3-tier architecture (primitive → semantic → component). Use when the user wants a color palette, type scale, spacing/shadow/radius/motion tokens, multi-brand theming, or wants to validate token files. Covers colors, typography, spacing, shadows, borders, breakpoints, motion, gradients, opacity, blur, sizing, states, theming.

Set up or run design QA gates — token + hardcoded-value lint, automated a11y (axe), contrast, visual regression across variants/states/themes/RTL, and the manual a11y checklist. Use when the user wants CI quality gates, to prevent design regressions, or to QA a component/screen before shipping.

The house rules for ANY design or UI work - the verification protocol (run the gate, never claim a number), the absolute no-emoji rule, token by intent, one shared theme, the eight states, one thing leads, and output completeness. Load this FIRST whenever building, reviewing, or theming a screen, component, or token set. Installed as a plugin, this skill carries what CLAUDE.md carries in the repo.

Design a UI component spec to the house quality bar — anatomy, variants, sizes, the 8 states, token mapping, and accessibility. Use when the user wants to design or document a component (button, input, tabs, toast, combobox, date picker, modal, etc.) at the spec level before or alongside code. For generating framework code, use design-code.

Generate production-ready, accessible, token-driven component code for ANY framework — React+Tailwind, Next.js, SwiftUI, Vue, Svelte, Angular, Solid, Web Components/Lit, React Native, Flutter, Jetpack Compose, vanilla CSS, or CSS-in-JS. Use when the user wants working UI code for a component or screen in a specific stack.

Use when the user wants a specific look/vibe/brand feel, or asks to make a design feel premium/expensive/non-generic.

Operate CC Safety Net: explain why a command was blocked, triage false positives, configure custom rulebooks, manage agent CLI integrations, and diagnose protection.

Launch and drive the real cc-safety-net CLI — the hook decision path, explain, status/doctor/statusline, logs, rule and policy config, and the local policy GUI — against an isolated home, capturing evidence. Use when a change needs proof in the running app, not just the test suite.

Use in the cc-safety-net repo when `bun run lint:comments` or `bun run check` reports a comment, a stale comment-allowlist entry, or a file it cannot parse, and before writing a code comment there. Moves what each comment says into code, a test, or the PR description instead of deleting it and losing it.

Use when working in the cc-safety-net repo to find non-obvious simplification candidates: dead, duplicated, speculative, over-built, or contract-exceeding surfaces in the shell parser, analyzer, guards, secret protection, policy, rules manager, audit log, hosts, CLI, or GUI. Produces evidence-backed proposals for the maintainer, not a pile of guesses.

End-to-end user research assistant — qualitative and quantitative. Use this skill whenever the user mentions user research, user interviews, discussion guides, interview guides, research plans, qualitative research, quantitative research, user surveys, survey design, usability studies, participant recruitment, research synthesis, interview transcripts, research reports, running studies with AI, or explicitly mentions Cookiy AI. Also trigger when users want to talk to customers, conduct discovery research, create a study or survey, analyze interview data, run AI-moderated interviews, or collect survey responses. Covers the full lifecycle: planning studies, creating discussion guides, running AI-moderated interviews (real or synthetic) via Cookiy, designing and distributing surveys, and synthesizing results into reports.
