What it does

Alt Text Edit is an agent skill from chef/chef-web-docs. Scan a Markdown file for images, audit every alt text value against accessibility and style guidelines, view each image in the workspace, draft accurate alt text, and edit the file in place. Use when you want to audit and fix image alt text for accessibility compliance and style quality. Triggers on: alt text, alternative text, image accessibility, fix alt text, audit alt text, missing alt text, edit alt text, image descriptions, accessibility, a11y, screen reader.

Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Accessibility. The repository describes itself as: All The Documentation.

When your agent uses it

  • You want to audit and fix image alt text for accessibility compliance and style quality
  • Alternative text
  • Image accessibility
  • Missing alt text

Example prompts

  • “/alt-text-edit”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Find all images
  2. Audit existing alt text
  3. View images and draft alt text
  4. Edit the file

What it can do on your machine

Read from SKILL.md and the folder at commit e0c87d0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash, markdown and html).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Alt Text Edit loads about 2.6k tokens when it runs. Until then it costs about 121 tokens; SKILL.md has 1,435 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~121
When it runs · the whole SKILL.md, loaded when a task matches
~2.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,435 words (~2,627 tokens).
