Design
input-image-alt

Input Image Alt is an Agent Skill for design published in the thedaviddias/Front-End-Checklist repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Use when reviewing rendered HTML, interactive components, or design-system patterns related to Provide alt text for image buttons. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/thedaviddias/Front-End-Checklist/blob/HEAD/skills/input-image-alt/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/input-image-alt, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

Provide alt text for image buttons

Without alt text, screen readers may read the file name of the image, leaving users unable to determine the function of the button.

Quick Reference

  • Add an alt attribute to <input type='image'>
  • Describe the action of the button, not just the image
  • Ensures the button's purpose is clear to assistive technology

Check

Verify that all elements have a non-empty 'alt' attribute.

Fix

Add an 'alt' attribute to the that describes the action performed when the button is clicked (e.g., 'Search', 'Submit').

Explain

Explain why image buttons require alternative text to communicate their function to users who cannot see the image.

Code Review

Review the rendered markup and interactive states that affect Provide alt text for image buttons. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
