At a glance

A skill your agent uses when reviewing templates, rendered HTML, or shared components related to Use semantic input type attributes.

  • Reviewing templates
  • 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
  • Shared components related to Use semantic input type attributes

What it does

Input Types is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing templates, rendered HTML, or shared components related to Use semantic input type attributes. Validate the final browser-facing markup, not just the source framework abstraction.

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`).

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 templates
  • Shared components related to Use semantic input type attributes

Example prompts

  • “/input-types”

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

Input Types loads about 487 tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 52 tokens; SKILL.md has 204 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~487
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.7k

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.

Use semantic input type attributes

Using type=text for every input forces mobile users to switch keyboards manually for email, phone, and number entry. The correct type also enables browser autofill to correctly identify fields for name, address, and payment data. Combined with autocomplete attributes, semantic types can make form completion 40% faster for returning users.

Quick Reference

  • type=email shows the @ keyboard on mobile and enables email format validation
  • type=tel shows the numeric phone keypad on mobile
  • type=number shows a numeric keypad; use inputmode=numeric for fields that look like numbers but aren't
  • type=date/time renders native pickers and returns standardized values

Check

Audit all input elements in this HTML file. Check whether each uses the most appropriate type attribute and autocomplete value.

Fix

Update input type attributes to semantic values and add appropriate autocomplete attributes for autofill support.

Explain

Explain the different HTML input types, what each one does on mobile keyboards, and how to combine them with autocomplete attributes.

Code Review

Review templates, server-rendered HTML, and shared components that output markup related to Use semantic input type attributes. Flag exact elements, attributes, and routes where the rendered HTML violates the rule.
