How to use the Descriptive Image Filenames Checker agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The filename-quality skill is an agent skill for the Front-End Checklist project. It teaches an AI coding agent to review the image files in a website project, flag names that hurt search and maintenance, and suggest or apply cleaner names. This guide covers what the skill does, how to install it, how to trigger it, and where to be careful before renaming anything.
Descriptive Image Filenames Checkerthedaviddias/Front-End-Checklist · MIT Download the skill Quick start
- 1Download the ZIP. Get the filename-quality skill ZIP from the Front-End Checklist page.
- 2Unzip it into a skills folder. Use ~/.claude/skills/ for a personal install or .claude/skills/ inside your project for a project-only install.
- 3Or upload it in the Claude apps. Go to Settings, then Capabilities, then Skills, and add the ZIP.
- 4Ask for a review. Describe the images or folder you want checked in plain language.
- 5Approve renames carefully. Review the suggested names and reference changes, then test the site before committing.
What the filename-quality skill makes the agent do
When the skill is active, the agent scans the image references in a project. The source says it checks HTML img tags, CSS url() rules, import statements and public or assets folders.
It flags filenames that are auto-generated (such as IMG_1234.jpg), generic (such as image1.jpg or photo.png), contain spaces, use underscores as word separators, or mix upper and lower case. It then suggests descriptive, lowercase, hyphen-separated names and can update references to the renamed files. For large renames it can write a migration script.
The skill is based on the idea that descriptive names help image search and make asset folders easier for a team to maintain. The source cites Google's image SEO guidance as the basis for the search part.
- Flags generic and camera-default names
- Flags spaces, underscores and mixed case
- Suggests names of about three to five words
- Can update HTML, CSS and JavaScript references
- Can write a migration script for large renames
Install the filename-quality skill
Download the ZIP for this skill from the Front-End Checklist page. The skill folder contains a SKILL.md file and a references/rule.md file.
For a personal install, unzip the folder into ~/.claude/skills/. For a single project, unzip it into the project's .claude/skills/ folder instead.
You can also upload the skill in the Claude apps. Go to Settings, then Capabilities, then Skills, and add the ZIP there.
- Personal install: ~/.claude/skills/
- Project install: .claude/skills/ inside your project
- Claude apps: Settings → Capabilities → Skills
How to trigger the skill with natural requests
You do not need a special command. Describe the task in plain language and mention images or filenames, and the agent can pick up the skill when it matches the request.
Be specific about scope. Name the folder or site section you care about so the agent reviews the right files.
- Review the image filenames in this project and list the ones that need work.
- Check the public/assets folder for names with spaces, underscores or uppercase letters.
- Rename the generic images in src/images to descriptive lowercase names and update the references.
- Write a migration script to rename our product photos and update every path that uses them.
Review the results before you rename anything
The skill's own guidance warns that renaming can break links and cached URLs. Filenames fixed by an external system or a CDN may not be safe to change. Check where each image is served from before you approve a rename.
A migration script can miss paths that are built dynamically in code, such as names assembled from variables. Test the site after a bulk rename and check that every image still loads.
To confirm a fix, the skill's guidance says to describe how to check it in browser DevTools, for example by looking at the loaded image URLs in the Network panel.
- Keep a copy or commit before a bulk rename
- Search for old filenames in your code after the change
- Load key pages and confirm images appear
- Check any external links or cached URLs that point to old names
What people use it for
- Tidying up a website's image folders before launch by replacing IMG_1234.jpg-style names with descriptive ones
- Giving a team consistent asset naming so new images follow the same lowercase hyphenated pattern
- Auditing the basic image SEO of a site by listing generic or spaced filenames
Frequently asked questions
How do I install the filename-quality skill?
Download the skill ZIP from the Front-End Checklist page and unzip it into ~/.claude/skills/ for personal use or into your project's .claude/skills/ folder. You can also upload the ZIP in the Claude apps under Settings, then Capabilities, then Skills.
Does the filename-quality skill require anything else?
The source lists no specific requirements for this skill. It does not run scripts and does not use the network, according to its listing.
Is the filename-quality skill free?
The skill is published under the MIT licence, as stated on its listing. The source does not mention prices, so check the licence text for the terms that apply.
Can the skill rename my images automatically?
The skill can suggest new names and update references to renamed files, and it can write a migration script for large renames. Review the changes yourself before running them, because the source warns that renames can break links.
Why does the skill avoid spaces and uppercase letters in filenames?
The source says spaces can cause URL encoding issues, such as %20 in the address, and recommends lowercase names with hyphens. Descriptive names also help search engines and team members understand each image.
When should I not use this skill?
Skip it when filenames are fixed by external systems or CDNs, because renaming can break links and cached URLs. Also be careful with large asset libraries renamed in bulk without testing, since a migration script can miss dynamically built paths.

Our verdict
This skill suits front-end developers tidying a site's image folders before launch, and teams that want consistent image naming for SEO and maintenance. It is less suitable where filenames are controlled by a CDN or outside system, or where a large library would be renamed without careful testing. Pick it for a focused naming audit, and look at other tools if you need automated image compression or delivery work.
