At a glance

A skill your agent uses when reviewing rendered HTML, interactive components, or design-system patterns related to Write in plain language.

  • Reviewing rendered HTML
  • SKILL.md covers Quick Reference, Check, Fix and Explain, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Interactive components

What it does

Plain Language is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing rendered HTML, interactive components, or design-system patterns related to Write in plain language. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).

It sits in Writing & Content, covering Plain language and style rules and Accessibility. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.

When your agent uses it

  • Reviewing rendered HTML
  • Interactive components
  • Design-system patterns related to Write in plain language

Example prompts

  • “/plain-language”

What it can do on your machine

Read from SKILL.md and the folder at commit e8d14d0. 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.

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

  • Network

    Links to these hosts (documentation or services it may open):

    • frontendchecklist.io

    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

Plain Language loads about 493 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 192 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~493
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.8k

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.

Write in plain language

Plain language helps users with cognitive disabilities, learning differences, attention disorders, non-native speakers, and anyone reading quickly or under stress.

Quick Reference

  • Use short sentences and common words
  • Define technical terms when first used
  • Write in active voice, not passive
  • Target reading level appropriate for your audience (often 8th grade)

Check

Review content for jargon, complex sentences, and unnecessary technical terms. Verify reading level is appropriate for the audience. Check that instructions are clear and actions are obvious.

Fix

Simplify complex sentences. Define technical terms when first used. Use short paragraphs and bullet points. Write in active voice. Target a reading level appropriate for your broadest audience.

Explain

Explain how plain language benefits users with cognitive disabilities, learning differences, attention disorders, non-native speakers, and anyone in a hurry or under stress.

Code Review

Review the rendered markup and interactive states that affect Write in plain language. 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.
