ux

ux is a skill for Claude Code, Codex from cwklurks/ship-score. It costs 0 tokens per session (6,653 once invoked), scanned A, original, MIT.

A checklist for reviewing a website’s user experience during a production-readiness audit. It runs seven predefined checks, including whether broken links show a helpful custom not-found page.

In plain words
What is it for?
Use it as part of a Ship Score audit to inspect navigation, error handling, and other visible parts of a website.
Why use it?
It provides a fixed way to find common user-facing problems before release. The excerpt does not identify all seven checks, so its full coverage cannot be described here.

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.

Security

Grade A, and why

ux 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 8d 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.

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 — 536 lines — stays where its author put it; the contents beside it link to each section on GitHub.

UX Category — Ship Score Sub-Skill

You are running the UX category of a Ship Score production readiness audit. Follow every instruction below precisely. Do not add checks beyond the 7 defined here. Do not skip checks. Report exactly what you find.


Context You Receive

The orchestrator passes you:

Framework: [name] ([key])
Signals: [comma-separated detected features]
Root: [absolute path to project root]

Use the key value to select the correct framework-specific search patterns below. If the key is unknown, use the Generic/Vite patterns.


Checks

Run all 7 checks in order. For each check, follow the verification steps, determine the status, and record the evidence.


Check 1: Custom 404 Page

Severity: High

What to look for:

A custom "not found" page that replaces the default framework 404 page. Without a custom 404, users who hit a broken link see a generic error page with no branding, navigation, or helpful links — a poor experience that increases bounce rate.

Framework-specific verification:

Framework What to glob / check
Next.js App Router (nextjs + app/ signal) Glob for app/not-found.tsx, app/not-found.ts, app/not-found.jsx, app/not-found.js. Also check route groups: app/(*)/not-found.tsx, app/(*)/not-found.jsx.
Next.js Pages Router (nextjs + pages/ signal) Glob for pages/404.tsx, pages/404.ts, pages/404.jsx, pages/404.js.
Astro (astro) Glob for src/pages/404.astro, src/pages/404.md, src/pages/404.mdx.
SvelteKit (svelte) Glob for src/routes/+error.svelte (SvelteKit uses a unified error page). Also check src/routes/+layout.svelte for error handling.
Nuxt (nuxt) Glob for error.vue at project root, or layouts/error.vue.
Vite/Generic (vite, node, unknown) Glob for public/404.html, 404.html, **/404.html. Also glob for **/NotFound.tsx, **/NotFound.jsx, **/NotFound.vue, **/NotFound.svelte, **/not-found.tsx, **/not-found.jsx in a pages/, views/, routes/, or components/ directory.

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.
