How to use the Accessible Notifications Checker agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The Accessible Notifications Checker is an agent skill that teaches an AI agent to review templates, rendered HTML and shared UI components for notifications that screen reader users can perceive. It covers form errors, success confirmations, toast messages and live updates. After this guide you will know how to install the skill, ask for a review in plain language, and read the results.
Accessible Notifications Checkerthedaviddias/Front-End-Checklist · MIT Download the skill Quick start
- 1Download the ZIP. Get the accessible-notifications ZIP from the directory page and unzip it.
- 2Place the folder. Move the unzipped folder into ~/.claude/skills/ for personal use or into your project's .claude/skills/ folder.
- 3Or upload it in the Claude apps. In the Claude apps, go to Settings → Capabilities → Skills and upload the ZIP.
- 4Ask for a review. Describe the templates, rendered HTML or components you want checked for accessible notifications.
- 5Read the findings. Check the flagged elements and attributes, and the suggested fixes.
- 6Verify in a browser. Confirm the fixes in the rendered page and test with a real screen reader, since the skill does not replace that.
What is an agent skill and what does this one make the agent do?
An agent skill is a folder of instructions that an AI agent loads when a task matches the skill's description. This skill is named accessible-notifications and is described as being for reviewing templates, rendered HTML, or shared components related to making notifications accessible.
When the skill is active, the agent checks that notification messages use ARIA live regions with a suitable role (alert or status) and a politeness setting (polite or assertive), and that messages stay visible long enough to be read and can be dismissed. It then flags the exact elements or attributes that break this rule and suggests fixes.
- Checks form errors, success messages and real-time updates
- Looks at the final browser-facing markup, not only the source framework code
- Reports exact elements, attributes and routes where the rendered HTML violates the rule
How do you install the Accessible Notifications skill?
Download the ZIP for this skill from the directory page and unzip it. The skill folder contains SKILL.md and references/rule.md. Place the unzipped folder in one of these locations:
- Personal use: ~/.claude/skills/ on your computer
- Single project: the .claude/skills/ folder inside your project
- Claude apps: upload the ZIP under Settings → Capabilities → Skills
How do you trigger the skill with a natural request?
You do not need a special command. Describe the review you want and mention notifications, toasts, live regions or form feedback. The skill's description matches requests about reviewing templates, rendered HTML or shared components for accessible notifications, so ask in those terms and point the agent at the files.
- Review the error and success messages in templates/checkout.html for accessible notifications
- Check our shared Toast component for ARIA live regions and role settings
- Audit the rendered HTML of the signup form for accessible form error messages
- Does our toast system use role=status or role=alert correctly?
What kind of output should you expect?
The skill asks the agent to check three things: whether notifications use aria-live regions, whether they have an appropriate role of alert or status, and whether they persist long enough to be read. The guidance pairs urgency with politeness: polite waits for the user to finish, while assertive interrupts. Expect the agent to name the specific element or attribute that fails and suggest a fix.
The reference file shows the expected patterns, including a status message with role="status" and aria-live="polite", an error with role="alert" and aria-live="assertive", and an empty live region container with aria-live="polite" and aria-atomic="true" for content injected dynamically.
<div role="status" aria-live="polite" class="notification">
Your changes have been saved.
</div>
<div role="alert" aria-live="assertive" class="notification notification--error">
Error: Please fill in all required fields.
</div>What are the limits of this skill?
This skill covers one rule about notifications. It is not a full accessibility audit, it does not cover the wider WCAG standard, and it does not replace testing with real screen readers. It also works best when the agent can see the final rendered HTML. Where markup is generated at runtime and the agent cannot see the output, the skill asks for browser-facing output to be validated, so give the agent rendered output where you can.
What does the skill need and what are its safety notes?
The skill lists no required tools or setup. It does not run scripts and does not use the network. Its files are SKILL.md and references/rule.md, which are plain instructions and reference material.
- Requires: nothing listed
- Runs scripts: no
- Uses network: no
What people use it for
- Reviewing a server-rendered form so that validation errors use role="alert"
- Checking a shared toast component for correct aria-live politeness
- Auditing success confirmations after saving settings
- Reviewing a live-updating status area for aria-atomic and aria-live settings
Frequently asked questions
How do I install the accessible-notifications skill?
Download the ZIP from the directory page and unzip it. Put the folder in ~/.claude/skills/ for personal use, in a project's .claude/skills/ folder, or upload the ZIP in the Claude apps under Settings → Capabilities → Skills.
Does this skill need any tools or setup?
The skill lists no requirements. It does not run scripts and does not use the network.
Is this skill a full accessibility audit?
No. It covers one rule about notifications, not the wider WCAG standard, and it does not replace testing with real screen readers.
When should I choose polite versus assertive?
Use polite for updates that can wait until the user finishes what they are doing, and assertive for urgent messages that should interrupt. The skill's guidance is to base the choice on urgency.
Why won't the skill work well on my framework's runtime-generated markup?
The skill validates browser-facing output. If markup is generated at runtime and the agent never sees the final rendered HTML, its review is limited, so supply rendered output where possible.
What license is the skill under?
The source is released under the MIT licence.

Our verdict
Use this skill if you are a front-end developer, a team reviewing shared components or server-rendered templates, or a designer or QA tester checking toast messages and form feedback. Pick a full accessibility audit tool or manual screen reader testing if you need coverage beyond notification markup.
