What it does

Use when the user wants to design, redesign, shape, critique, audit, polish, clarify, distill, harden, optimize, adapt, animate, colorize, extract, or otherwise improve a frontend interface. Covers websites, landing pages, dashboards, product UI, app shells, components, forms, settings, onboarding, and empty states. Handles UX review, visual hierarchy, information architecture, cognitive load, accessibility, performance, responsive behavior, theming, anti-patterns, typography, fonts, spacing, layout, alignment, color, motion, micro-interactions, UX copy, error states, edge cases, i18n, and…

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

9## Setup
10
11You MUST do these steps before proceeding:
12
131. Run node .agents/skills/impeccable/scripts/context.mjs once per session. If the request names or implies a file, route, or app inside a monorepo, infer the concrete path and run node .agents/skills/impeccable/scripts/context.mjs --target <path> instead. If you've already seen its output in this conversation, do not re-run it. The script either prints the project's PRODUCT.md (and DESIGN.md when present) as a markdown block, or tells you it's missing. Follow whatever it prints. **If it reports NO_PRODUCT_MD, stop and follow reference/init.md before doing anything else.** If the output ends with an UPDATE_AVAILABLE directive, follow it (ask the user once about updating, then continue). It never blocks the current task.
142. If the user invoked a sub-command (craft, shape, audit, polish, ...), you MUST read reference/<command>.md next. Non-optional. The reference defines the command's flow; without it you will skip steps the user expects.
153. Familiarize yourself with any existing design system, conventions, and components in the code. Read at least one project file (CSS / tokens / theme / a representative component or page). **Required even when you've loaded a sub-command reference in step 2.** Don't reinvent the wheel; use what's there when it works, branch out when the UX wins.
164. Read the matching register reference. **This is non-optional; skipping it produces generic output.** If the project is marketing, a landing page, a campaign, long-form content, or a portfolio (design IS the product), read reference/brand.md. If it is app UI, admin, a dashboard, or a tool (design SERVES the product), read reference/product.md. Pick by first match: (1) task cue ("landing page" vs "dashboard"); (2) surface in focus (the page, file, or route being worked on); (3) register field in PRODUCT.md.
175. **If the project is brand-new (no existing CSS tokens / theme / committed brand colors found in step 3)**, run node .agents/skills/impeccable/scripts/palette.mjs to receive a brand seed color and composition guidance. This is the anchor for your primary brand color. Compose the rest of the palette (bg, surface, ink, accent, muted) around it per the script's instructions. Use OKLCH throughout. **Skip this step only if step 3 found committed brand colors in existing tokens; in that case identity-preservation wins.**
18
19## Design guidance
20
21Produce ready-to-ship, production-grade code, not prototypes or starting points. Take no shortcuts unless the user asks for them (when in doubt, ask). Don't stop until arriving at a complete implementation (beautiful, responsive, fast, precise, bug-free, on brand). You take attention to detail seriously: every page, section or component crafted is battle tested using the tools available to you (browser screenshotting, computer use, etc). GPT is capable of extraordinary work. Don't hold back.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈240
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
98,960
on trigger
The instruction body and 98 supporting files, read only when the skill fires.
49.6%
of a 200k window
Ten skills this size would not fit in the window together.
050k100k150k200k context window

99.2k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

99 files, 2127.3 kB on disk. Mostly text — the instructions the model reads — with 66 scripts in it that your client would run only if the instructions tell it to.

What is not in it

A skill installs nothing and depends on nothing: it is a folder your client reads. This one carries 66 scripts beside the text, so the bundle is 99 files you can review in full before installing.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Impeccable · 99.2k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/davidanthonyn-impeccable/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/impeccable" ] && { [ ! -e .claude/skills/impeccable ] || { mv .claude/skills/impeccable "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/impeccable" .claude/skills/ && echo "Installed .claude/skills/impeccable"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add davidanthonyn/impeccable

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/impeccable/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/davidanthonyn-impeccable/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/impeccable" ] && { [ ! -e ~/.claude/skills/impeccable ] || { mv ~/.claude/skills/impeccable "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/impeccable" ~/.claude/skills/ && echo "Installed ~/.claude/skills/impeccable" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/impeccable/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

v3.8.0 is what is on the shelf; no release here carries a date. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

v3.8.0
  • No earlier releases have been published to the marketplace.
Pinning

The install command always fetches the release that is current the day you run it — v3.8.0 today — and cannot ask for an earlier one. The copy on your disk does not change until you run it again.
