How to use the Iframe Title Checker agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The frame-title skill is an agent skill that tells an AI coding agent to review your web page markup and check that every iframe or frame has a non-empty, descriptive title attribute. It is written for front-end developers, accessibility reviewers and designers who want a quick check on embedded content such as maps, videos or widgets. By the end of this guide you will know what the skill does, how to install it, how to ask for it in plain language and what to expect from its output.
Iframe Title Checkerthedaviddias/Front-End-Checklist · MIT Download the skill Quick start
- 1Download the ZIP. Get the frame-title ZIP from the Front-End Checklist page for this skill.
- 2Unzip the skill folder. Extract the archive so you have a folder containing SKILL.md and references/rule.md.
- 3Place it in the skills folder. Move the folder to ~/.claude/skills/ for personal use, or to .claude/skills/ in a project.
- 4Or upload in the Claude apps. Go to Settings → Capabilities → Skills and upload the ZIP instead.
- 5Ask for a review. Point the agent at your HTML or component and ask it to check iframe titles.
- 6Fix and verify. Apply the suggested titles, then confirm them with browser accessibility tools or a screen reader.
What is an agent skill and what does frame-title make the agent do?
An agent skill is a folder containing a SKILL.md file and any supporting files that an AI agent can load when a task matches the skill's description. The skill tells the agent how to approach that task.
The frame-title skill covers one accessibility rule: iframes and frames must have a title attribute that describes their purpose or content. When it is active, the agent reviews web page markup and components, confirms each iframe or frame has a non-empty, descriptive title, and flags missing or vague titles with suggested wording.
- Checks that every <iframe> and <frame> element has a non-empty title attribute
- Flags missing titles and generic titles such as "frame"
- Suggests more descriptive wording for the embedded content
Why the title on an iframe matters
Screen reader users rely on frame titles to understand what embedded content is before they enter it. Without a title, a user may have to step into an advertisement or social media widget just to find out what it is.
The source's examples show the difference. A title such as "Map of our office location" or "Tutorial video: How to use our product" tells the user what they will find, while a bare iframe with no title, or one titled only "frame", gives them nothing useful.
<iframe title="Map of our office location" src="https://maps.google.com/..."></iframe>Install the frame-title skill
The skill is distributed as a ZIP file from the Front-End Checklist page for this item. Download the ZIP and unzip it. The skill folder contains SKILL.md and references/rule.md.
For a personal install, place the unzipped skill folder in ~/.claude/skills/. To make it available to one project only, place it in that project's .claude/skills/ folder.
In the Claude apps you can instead upload the ZIP under Settings → Capabilities → Skills.
- Personal install: ~/.claude/skills/
- Project install: .claude/skills/ inside your project
- Claude apps: Settings → Capabilities → Skills, then upload the ZIP
Trigger the skill with natural requests
You do not need a special command. The agent decides to use a skill based on its description, which for this skill covers reviewing rendered HTML, components and design-system patterns related to titles for iframes and frames. Asking in ordinary language that touches on iframes, embeds or frame titles should be enough.
Be specific about what you want reviewed. Pointing the agent at a file or component gives it more to work with than a general question.
- Check the iframes in index.html for missing or vague title attributes.
- Review this contact page component for embedded content that lacks a title.
- Do the embedded ads and social widgets on this page have accessible titles?
- Suggest better titles for the iframes in this component.
Read and act on the results
The agent's review should point to the exact elements it checked and explain what is wrong with each title. Use its suggested wording as a starting point, then make sure it describes the actual content of that frame on your page.
The skill's code review guidance also asks the agent to note how to verify fixes with browser accessibility tooling or assistive technology. Do that check yourself, since the skill cannot test with real assistive technology.
- Confirm each iframe has a non-empty title attribute
- Replace generic titles like "frame" with a description of the content
- Test the fix with browser accessibility tools or a screen reader
What the skill needs and safety notes
The item lists no requirements. It does not run scripts and does not use the network, according to the listing. The skill is provided under the MIT licence.
The skill covers only this one check. It is not a full accessibility audit, and it does not replace testing with real assistive technology. If your project has no iframes or frames, the rule does not apply.
- Requires: nothing listed
- Runs scripts: no
- Uses network: no
- Licence: MIT
What people use it for
- Reviewing a landing page before release to confirm embedded maps and videos have descriptive titles.
- Auditing third-party ad or social widget containers for missing titles.
- Checking a design-system embed component so every instance gets a title prop or attribute.
- Preparing a list of title fixes for a developer to apply in a pull request.
Frequently asked questions
Is the frame-title skill free?
The skill is licensed under MIT, according to the listing. The source does not mention pricing for it.
What do I need to run the frame-title skill?
The listing lists no requirements. It does not run scripts and does not use the network.
Where do I install an agent skill like this?
Unzip it into ~/.claude/skills/ for personal use or .claude/skills/ inside a project. In the Claude apps, upload the ZIP under Settings → Capabilities → Skills.
Will the skill check my whole site for accessibility?
No. It only checks that iframes and frames have a non-empty, descriptive title. It is not a full accessibility audit and cannot test with real assistive technology.
What makes a good iframe title?
A good title describes what the embedded content is, such as "Map of our office location" or "Tutorial video: How to use our product". Generic words like "frame" do not help screen reader users.
How does this compare with other accessibility checkers?
The source does not compare this skill with other tools. Its scope is narrow: one rule about frame titles. Use it alongside a broader audit and manual testing.

Our verdict
Use frame-title if you review HTML or components that embed iframes or frames and want a fast, focused check on their titles. Pick a full accessibility audit or testing with real assistive technology if you need coverage beyond this single rule, or if your project has no embedded frames.
