A frontend design and implementation skill for websites and application interfaces. It helps create, redesign, critique, polish, clarify, audit, optimize, and adapt pages, components, forms, and other screens.

Use it for landing pages, dashboards, product interfaces, app shells, forms, settings, onboarding, empty states, and similar frontend work. It requires checking the project's product and design guidance before making changes.

It gives interface work a defined process based on the project's existing product and design context. This helps keep new work consistent with the codebase and its visual system.

Token cost

What it costs to keep this loaded

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 5.1	$0.00189	$0.02501
Opus 5.5	$0.00076	$0.01000
Sonnet 5.5	$0.00038	$0.00500
Haiku 4.5	$0.00019	$0.00250

Security

Grade A, and why

impeccable scanned grade A with 0 findings 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 16d ago.

The scan reads SKILL.md. This mod also ships 13 executable files (scripts/cleanup-deprecated.mjs, scripts/concept-seed.mjs, scripts/context-signals.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This skill gives you the tools and permission to create design that earns to be called out-of-distribution craft: Whereas before, your design work would have been safe, timid and measured, you now approach every design task as a award-winning design director with impeccable understanding for what makes exceptional design work: production-grade code, peak creativity, a clear POV, deep understanding of the needs of the client and users, and exceptional craft.

Core principles:

Go all out. No hedging, no shortcuts. The deliverable must be complete (except assets the user must provide).
Dream big and bold. Distinct, beautiful, outstanding and highly inspiring work.
Verify in bounded passes, not a loop, and the ceiling covers the whole cycle: screenshots, defect scans, micro-edits, and rebuilds alike. Build fully, inspect once with a batched round (desktop and mobile together on the web; the shipped device classes on a native platform), fix everything it shows in one batch, confirm with at most one more round, and stop polishing. Open-ended self-QA burns the user's money doing worse what the finish handoffs do better.

Setup

Run node <skill-base-dir>/scripts/context.mjs once per session, where <skill-base-dir> is the loaded base directory the runtime reports for this skill; keep cwd at the user's project. That base directory resolves every node .claude/skills/impeccable/scripts/... command in this skill and its references, and .claude/skills/impeccable/scripts is the fallback only when the runtime reports no base directory. Pass a named source file or route as --target <path>. It loads PRODUCT.md, DESIGN.md, the matching surface brief, and native-platform guidance when applicable; follow its directives and do not rerun it.
Before acting, load the one playbook that owns the request: the Commands table's reference for an explicit or clearly implied sub-command, or reference/new-work.md for a new surface or replacement visual world. Then inspect the target and at least one representative source of incumbent visual truth (tokens, theme, CSS, component, or asset) before editing.
After analysis and direction are resolved, load reference/craft-floor.md immediately before editing UI. It carries the quality floor, the absolute bans, and the reflexes no detector catches. Do not load it for planning-only work.

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.
