AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

Impeccable provides a structured approach to designing, auditing, and refining frontend interfaces including websites, dashboards, and mobile applications. It operates by establishing product context through documentation and applying specific design modes—Persuade, Operate, Read, and Experience—to guide the visual and functional direction of a project. The skill supports a wide range of tasks from initial planning and documentation to technical audits, visual refinements, and animation, ensuring that design changes remain consistent with the established visual world.

What it does

Audits UI for accessibility, performance, and responsive behavior.
Generates design documentation from existing project code.
Refines visual elements through commands like colorize, typeset, and layout.
Provides tools to plan UX and UI before implementation.
Manages design system tokens and component extraction.
Supports iterative design through live variant generation and testing.

When to use it

When you need to perform a UX critique or technical audit of an existing interface.
When starting a new design surface or defining a new visual world.
When you need to polish or refine UI components before a release.
When you need to adapt an interface for different screen sizes or platforms.
When you need to add purposeful animations or improve typography hierarchy.

Advantages

Provides a consistent framework for design decisions across different project types.
Integrates technical audits directly into the design workflow.
Supports specific modes to align design output with user intent.
Enables structured documentation of product and design context.
Offers granular control over UI refinements through specialized commands.

Usage examples

“impeccable audit src/components/Dashboard.tsx”: The agent performs a technical quality check on the dashboard component, reporting on accessibility, performance, and responsiveness.
“impeccable polish src/landing-page.css”: The agent executes a final quality pass on the landing page styles to ensure visual consistency and adherence to the design system.
“impeccable animate hero-section”: The agent applies purposeful motion and animation to the specified hero section based on the project's design mode.
“impeccable init”: The agent captures the current project context and creates a PRODUCT.md file to serve as the foundation for future design work.

Documentation by Paul Bakaus

This skill gives you the tools and permission to make design that earns the name out-of-distribution craft. Work as an award-winning design director would: production-grade code, a clear POV, a deep grasp of what the client and its users need, and exceptional craft.

Core principles:

Finish the job. No hedging, no shortcuts: the deliverable is complete, except assets the user must provide.
Scale ambition to the surface's mode (see Modes). Persuade and Experience get full commitment: bold, distinct work with a point of view. On Operate and Read, ambition shows as precision and restraint, and patterns the visitor already knows earn their place.
Verify by looking at the rendered result at the sizes it ships at, and batch the checks: fix what one look shows before looking again, rather than screenshotting after every tweak.

Setup

Run "${CLAUDE_SKILL_DIR}/scripts/impeccable" context once per session, where ${CLAUDE_SKILL_DIR} is the directory that contains this SKILL.md (the skill folder, not a plugin root two levels above it); keep cwd at the user's project. Every "${CLAUDE_SKILL_DIR}/scripts/impeccable" <verb> command in this skill and its references resolves against that base directory. In reference files, replace the skill-base-dir placeholder with this directory before running commands; it is not a shell variable. On a Windows shell without sh, call & "${CLAUDE_SKILL_DIR}/scripts/impeccable.cmd" instead. The launcher runs a self-contained binary that ships next to it or is downloaded once on first run; no Node or other runtime is required. 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.
Load the request's playbook: its Commands-table reference for an explicit/implied sub-command, or reference/new-work.md for a new surface or replacement visual world. Inspect target and incumbent visual truth before editing. When the app cannot run, start with committed visual-regression goldens or screenshot fixtures; verify target and freshness against current tokens, CSS, components, or assets, resolve conflicts, and compare theme/variant captures.
After resolving analysis and direction, read reference/craft-floor.md immediately before any UI edit, including small refinements. It carries the quality floor, the absolute bans, and the reflexes no detector catches. Do not load it for planning-only work.

Launcher unavailable: On refusal or failure, send a separate message before the next tool call: “Context loading did not run; I’ll read the existing project context directly.” Then read existing PRODUCT.md and DESIGN.md without inventing missing context, follow applicable steps 2–3, including reading reference/craft-floor.md immediately before any UI edit, and continue through permitted tools. This applies to planning and editing; launcher failure alone does not block either.

How to design

The brief wins. Honor pinned aesthetics, eras, materials, fonts, and palettes even when they conflict with a saturated-pattern warning. Redirecting a clear brief toward your taste is failure.
Refinement preserves; redesign replaces. Refinement keeps the incumbent identity, behavior, copy, and everything outside scope. Ask before replacing factual copy or adding claims. Redesign keeps product truth, content, function, native affordances, and constraints, but treats the old look as evidence and anti-reference; choose a replacement world in new-work and replace DESIGN.md. Never split the difference into polish on the discarded look.
Loaded symbols stay out of the decoration. A subject's world does not license emblems tied to militarism, supremacy, or hate movements as motifs, badges, or ornament, such as the Rising Sun flag's rays, the Confederate battle flag, or Nazi-era insignia and their stylised variants; reach for that world's neutral forms instead. Content that documents such a symbol as fact stays as it is.
Visual authority is evidence, not a filename. Missing DESIGN.md alone does not make a project greenfield; new-work decides whether to preserve, expand, or replace the incumbent world.

Modes

The mode names what the visitor's success looks like on this surface.

Persuade: the visitor decides and acts; design is the product. Landing pages, marketing, campaigns, pricing. Earn attention and action. Ship real imagery when the brief needs it; follow the committed world, not category habit.
Operate: the visitor completes a task. App UI, dashboards, editors, admin, settings, tools. Scanability, consistency, native expectations, and the real usage scene outrank expression. Brand lives in precise details.
Read: the visitor understands something. Docs, articles, guides, help, changelogs. Structure for comprehension, then make the reading experience worth staying in.
Experience: the visitor is inside the work itself. Portfolios, galleries, showcases. Let the artifact lead from the first viewport; the interface recedes.

Choose the mode from the requested surface, not the product, and persist it only in that surface brief. A tool's landing page is still Persuade; a fashion house's documentation is still Read; a docs index is Read, not Persuade. See new-work.md for new surfaces and operate.md for deeper Operate/Read guidance.

Routing:

No argument: read routing.md and present its context-aware menu; never auto-run a command.
Explicit or clearly implied request to run a command: load its reference (native variant on native platforms) and follow it. Ask once if two commands fit.
Workflow or command-selection question: read Workflow questions.
Otherwise: treat the request as general design work. Missing PRODUCT.md routes a new surface or replacement world through init, then new-work; a narrow refinement of existing code proceeds on the incumbent implementation as impeccable context directs, offering init afterward rather than blocking on it.
teach aliases init. craft is a deprecated alias for ordinary new-work and adds nothing. shape owns task discovery, then enters new-work only for visual-world and surface-concept decisions.

After init writes PRODUCT.md, resume without rerunning impeccable context; init loads the native platform reference itself when the platform it recorded is ios, android, or adaptive.

Pin / Unpin: "${CLAUDE_SKILL_DIR}/scripts/impeccable" pin <pin|unpin> <command> creates or removes a standalone /<command> shortcut. Report the script's result concisely; relay stderr verbatim on error.

Doctor: /impeccable doctor reports and repairs drift between this project's Impeccable artifacts (PRODUCT.md, DESIGN.md and its sidecar, config, surface briefs, the hook) and what this version reads. Load reference/doctor.md when the user invokes it, or when they ask what is out of date, stale, or needs refreshing. A CONTEXT_STALE directive in Setup's output is the cheap subset of the same report; act on it there per its own instructions rather than running doctor unasked.

Never repair drift as a side effect of a design task. A CONTEXT_STALE finding is reported, not acted on, unless the user asks. The one exception is a finding marked auto, which the next write to that file performs anyway.

reference/live-setup.md

One-time live-mode project setup. Loaded from live.md only when impeccable live reports config_missing / config_invalid, when configDrift needs handling, or when the config lacks cspChecked. Not part of the per-session hot path.

Write the config

Create the file at the path the boot reported (default .impeccable/live/config.json):

{
  "files": ["<path-or-glob>", "<path-or-glob>", ...],
  "exclude": ["<optional-glob>", ...],
  "insertBefore": "</body>",
  "commentSyntax": "html",
  "cspChecked": true
}

files is the inject target: the HTML files the browser actually loads, not necessarily source (tracked vs generated does not matter here; wrap has its own generated-file guard). Entries are literal paths or globs. exclude (optional) skips files a files glob would otherwise include (email templates, demo fixtures). cspChecked records that the CSP step below has run; absent on first setup.

Hard-excluded paths (cannot be overridden): **/node_modules/** and **/.git/**; injecting there would instrument third-party code.

Glob syntax: ** matches any number of segments (including zero), * matches within a segment, ? matches one character. Paths are project-root-relative with forward slashes.

Framework	`files`	`insertBefore`	`commentSyntax`
SPA with single shell (Vite / React / Plain HTML)	`["index.html"]`	`</body>`	`html`
Next.js (App Router)	`["app/layout.tsx"]`	`</body>`	`jsx`
Next.js (Pages)	`["pages/_document.tsx"]`	`</body>`	`jsx`
Nuxt	`["app.vue"]`	`</body>`	`html`
Svelte / SvelteKit	`["src/app.html"]`	`</body>`	`html`
TanStack Router (SPA, Vite)	`["index.html"]`	`</body>`	`html`
TanStack Start (SSR)	`["src/routes/__root.tsx"]`	`<Scripts`	`jsx`
Astro	`[" <root layout .astro>"]`	`</body>`	`html`
Multi-page (separate HTML per route)	`["public/*/.html"]` glob over the served dir	`</body>`	`html`

Pick an anchor that exists in every file (</body> almost always works); insertAfter matches after a line instead. For multi-page sites prefer a glob so new pages are picked up automatically. For sites whose pages are rebuilt by a generator, the inject survives only until the next regeneration: re-run impeccable live after each build (accept is unaffected; it writes true source via the fallback flow).

Framework adapters (auto-detected at inject time). Every inject records what it wrote in .impeccable/live/inject-journal.json; the next inject or remove heals artifacts a crash or wrong-directory stop left behind. SvelteKit, Nuxt, and TanStack Start server-render their document shell, so a raw <script> in the entry template will not execute reliably; impeccable live-inject detects them and routes to a dedicated adapter (SvelteKit: dev-only root component from +layout.svelte; Nuxt: dev-only .client.ts plugin; TanStack Start: a generated dev-only ImpeccableLiveRoot component in __root). The files value stays a valid detection/CSP hint but is not the literal insertion site. A plain TanStack Router SPA takes the baseline Vite path.

Config drift

On every boot the project is scanned for HTML files under common page roots (public/, src/, app/, pages/) that the resolved files list does not cover; they surface as configDrift.orphans with a hint. Tell the user once per session which files are uncovered and offer to add them or switch files to a glob. Never auto-update the config; the user decides. configDrift is null when there is no drift.

CSP detection (first-time only)

Keep all allowances below development-only, including manual middleware and meta-tag edits. Do not change a deployed production site's CSP to load the localhost helper; see live.md for production inspection alternatives.

If config.cspChecked === true, skip this whole section; the user was already asked once.

"<skill-base-dir>/scripts/impeccable" detect-csp

Output { shape, signals }; the shape names the patch mechanism, so one template covers many frameworks:

null: no CSP; write the config with cspChecked: true and stop here.
append-arrays: CSP as structured directive arrays; auto-patchable (monorepo helpers with additionalScriptSrc/additionalConnectSrc, SvelteKit kit.csp.directives, Nuxt nuxt-security).
append-string: CSP as a literal value string; auto-patchable (inline next.config.* headers(), Nuxt routeRules).
middleware / meta-tag: detected but not auto-patched. Show the user the detected files, ask them to add http://localhost:8400 to script-src and connect-src manually, then mark cspChecked: true and proceed.

CSP patch needed. I detected a Content Security Policy in your project that blocks http://localhost:8400: the live picker won't load without an allowance. Here's the change I'd make:
[file: <patchTarget>]
[exact diff, 2-5 lines]
It's guarded by NODE_ENV === "development" so the extra entry only appears in dev and never reaches production. You can remove it any time by reverting this file. Apply? [y/n]

On "no": skip the patch, note that live will not work until the allowance is added manually, and still write cspChecked: true (the question has been asked). On "yes": apply the shape's patch below, then write cspChecked: true.

append-arrays

Declare near the top of the file that holds the CSP arrays, then append ...__impeccableLiveDev to the script-src and connect-src arrays:

// Dev-only allowance so impeccable live mode can load. Guarded by NODE_ENV.
const __impeccableLiveDev =
  process.env.NODE_ENV === "development" ? ["http://localhost:8400"] : [];

Per-framework: Next.js + monorepo helper: edit the app's next.config.* (not the shared helper), appending to additionalScriptSrc / additionalConnectSrc. SvelteKit: svelte.config.js, kit.csp.directives['script-src'] and ['connect-src']. Nuxt + nuxt-security: nuxt.config.*, security.headers.contentSecurityPolicy['script-src'] and ['connect-src']. Reference outputs: nextjs-turborepo/expected-after-patch.ts, sveltekit-csp/expected-after-patch.js. Idempotency: if __impeccableLiveDev already exists in the file, the patch is applied; just mark cspChecked: true.

append-string

Two-point patch: declare a dev-only string, interpolate it into the CSP value at both directives (leading space so it concatenates cleanly; convert literals to template strings as part of the edit):

// Dev-only allowance so impeccable live mode can load.
const __impeccableLiveDev =
  process.env.NODE_ENV === "development" ? " http://localhost:8400" : "";

script-src 'self' 'unsafe-inline' becomes `script-src 'self' 'unsafe-inline'${__impeccableLiveDev}`
connect-src 'self' becomes `connect-src 'self'${__impeccableLiveDev}`

Per-framework: Next.js inline headers() in next.config.*; Nuxt routeRules['/**'].headers['Content-Security-Policy'] in nuxt.config.*. Reference outputs: nextjs-inline-csp/expected-after-patch.js, nuxt-csp/expected-after-patch.ts.

Troubleshooting

If the user said "no" to the CSP patch and later reports live not working: their dev CSP blocks http://localhost:8400. Delete cspChecked from .impeccable/live/config.json and re-run impeccable live; setup asks again.

After setup, re-run impeccable live.
