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 5.1 | $0.00068 | $0.01232 |
| Opus 5 | $0.00034 | $0.00616 |
| Sonnet 5 | $0.00014 | $0.00246 |
| Haiku 4.5 | $0.00007 | $0.00123 |
Grade A, and why
accesslint-diff 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 10d 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.
This is a copy
100% identical to accesslint-diff — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Default branch: !git symbolic-ref refs/remotes/origin/HEAD --short 2>/dev/null | sed 's|.*/||' || echo main
Report only what changed. Locate; don't fix. If no URL in $ARGUMENTS, ask for one.
Parse $ARGUMENTS: strip --branch <name> if present → branch mode. If --branch has no value, use the default branch above. Remainder is the URL.
When to Use
- Use this skill when the task matches this description: Diff a live page's accessibility violations against a baseline — by default compares uncommitted changes (stash-based), or pass --branch [] to diff against a branch. Reports only new violations introduced, violations fixed, and pre-existing count. Use
scanfor a full audit with no diffing.
1. Audit
PORT=$(npx -y @accesslint/chrome@latest ensure | node -e 'process.stdin.on("data",d=>process.stdout.write(""+JSON.parse(d).port))')
Stash mode (default — uncommitted changes). Tell the user first: "Running in diff mode — stashing your changes to capture a baseline, then restoring. Your working tree will be fully restored." If git stash push fails, warn and exit.
git stash push -u -m "accesslint-diff-baseline"
npx -y @accesslint/cli@latest "<url>" --port "$PORT" --snapshot accesslint-diff --snapshot-dir /tmp --update-snapshot
git stash pop && sleep 2
npx -y @accesslint/cli@latest "<url>" --port "$PORT" --snapshot accesslint-diff --snapshot-dir /tmp --format json
Branch mode (--branch <name>). Tell the user first: "Diffing against <name> — checking out that branch to capture a baseline, then restoring. Your working tree will be fully restored."
Branch switching triggers a rebuild but not a browser reload — the CLI opens a fresh tab each time so it always reads the current build. Use --wait-for "<selector>" to gate the audit until the rebuild is ready; without it, warn the user that a slow build may yield a stale baseline.
Keep the branch value in the quoted branch variable below; never paste or evaluate a branch name as shell syntax.
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.

accesslint-diff is a skill published in the GitHub repository lingxling/awesome-skills-cn (281 stars, last pushed 1mo ago), licensed MIT. It adds 68 tokens to every session and 1,232 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to accesslint-diff, differing in 0 lines, and is treated as a copy.

artifacts-builder
Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.
accessibility-audit
A review guide for checking whether webpages, components, prototypes, or designs are accessible to people with different needs. It uses WCAG 2.2 AA, a widely used set of web-accessibility requirements, as its default standard.
polish-pass
A final review checklist for an interface before it is shown to customers, teammates, or other stakeholders. It checks accessibility, visual hierarchy, overly generic AI-style design, and interaction states such as hover, focus, loading, success, and failure.
frontend-aesthetic-direction
A skill for choosing a complete visual direction for a new frontend project with no existing brand or design system. It defines rules for typography, colors, spacing, shapes, components, imagery, icons, and motion.
interaction-states-pass
A review skill for checking whether interactive controls give appropriate feedback in their resting, focused, active, loading, successful, and error states. It applies only the states that make sense for each control.
make-a-prototype
A skill for building clickable prototypes with working navigation, inputs, validation, loading, and success or failure feedback. A prototype is a test version of a product flow, using local simulated data unless a real connection is separately approved.
