Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00183 | $0.04454 |
| Opus 5 | $0.00092 | $0.02227 |
| Sonnet 5 | $0.00037 | $0.00891 |
| Haiku 4.5 | $0.00018 | $0.00445 |
Grade A, and why
frontend scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
description: "MUST USE for frontend/web UI/UX/visual work: building, styling, redesigning pages/components, React setup, performance audits, visual QA, taste, and polish. Routes four rulesets: design taste router and bra How it starts
The opening of the file, as written. The whole thing — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend
This file is a router, not a rulebook. The rules live in four rulesets under references/; your first job is to load the smallest set of files that covers the request, state which you loaded in one sentence, then execute under their guidance. Loading nothing and freestyling produces the generic AI-slop output this skill exists to prevent; loading everything wastes context and creates contradictory instructions.
The bar is not clean-and-correct — it is work a senior designer at Linear, Stripe, or Supabase would ship. Correct-but-flat is a failure, not a finish. Protect the surface as hard as you protect the build: design is a first-class deliverable, not a one-shot decision you lock and walk away from.
Phase 0 — Route (before any UI work)
| Request involves… | Read |
|---|---|
| ANY UI implementation, styling, redesign, mockup, or visual decision | references/design/README.md FIRST. It enforces two mandatory gates — the Design System Gate (a DESIGN.md must exist before any component is written) and the React Dev Tooling Gate (react-grab / react-scan / react-doctor installed by default) — then routes to the taste and brand references below. |
| Interaction or motion work — micro-interactions, animated components, transitions, gestures, hover/press/state feedback, "make it feel alive" | ALSO references/design/interaction-skill.md. The beui.dev catalog is the mandatory interaction reference: find the nearest pattern, read its real source through the file's curl recipe, and adapt the mechanism to DESIGN.md motion tokens. It stacks on the routed style skill — never replaces it. |
| Writing or modifying frontend code, OR auditing performance / SEO / accessibility / quality | ALSO references/perfection/README.md. Lighthouse 100 in every category, measured on real Playwright Chromium (never the lighthouse CLI), achieved through architecture — never by dropping animations or hiding content. |
| Looking up a concrete style, color palette, font pairing, chart type, landing-page structure, or UX guideline — or generating a project design system from keywords | references/ui-ux-db/README.md. A searchable CSV database with a CLI; a lookup tool, not a posture. Load on demand; design stays the source of truth for taste and the DESIGN.md contract. |
ANY implementation or redesign that creates or updates DESIGN.md — plus explicit operating-layer asks (personas, critique, debt, handoff, synthetic user testing) |
references/designpowers/README.md + references/designpowers/lane-c-review.md. An internal frontend ruleset, not a separate skill: lane-c is the Phase Final flatness/critique reviewer, and its accessibility-constraints and accepted-debt language fills the required DESIGN.md sections. Load other lanes only when their phase applies. |
What ships with it
60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 2d ago First seen · 148 lines · 183 tokens per session scan A cb3a0ca65af2
frontend is a skill published in the GitHub repository code-yeongyu/lazycodex (3,350 stars, last pushed 23d ago), licensed MIT. It adds 183 tokens to every session and 4,454 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
