At a glance

A skill your agent uses when auditing PWA readiness, adding an install prompt, or preparing a web app for submission to Microsoft Store or Google Play via PWA Builder.

  • Auditing PWA readiness
  • 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
  • Adding an install prompt

What it does

Pwa Installability is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing PWA readiness, adding an install prompt, or preparing a web app for submission to Microsoft Store or Google Play via PWA Builder.

Its SKILL.md is about 450 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

  • Auditing PWA readiness
  • Adding an install prompt
  • Preparing a web app for submission to Microsoft Store
  • Google Play via PWA Builder

Example prompts

  • “/pwa-installability”

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

Pwa Installability loads about 450 tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 200 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~450
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

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.

Meet PWA installability criteria

Installable PWAs appear in the browser's address bar install prompt and in app stores, giving users a native-app experience without an app store listing. Studies consistently show that installed PWAs have higher engagement and retention than browser-only equivalents — users who install spend 3× more time in the app on average.

Quick Reference

  • Serve the app over HTTPS (required by browsers)
  • Link a valid web app manifest with name, icons, start_url, and display
  • Provide a 192×192 and 512×512 icon; add a maskable variant for Android
  • Register a service worker that responds with 200 when offline

Check

Check whether this site meets the PWA installability criteria: HTTPS, valid manifest, service worker, and appropriate icons.

Fix

Add or fix the web app manifest, ensure a service worker is registered, and provide correctly sized maskable icons.

Explain

Explain what makes a web app installable as a PWA and what the manifest display modes mean for the user experience.

Code Review

Review the manifest.json and icon assets. Flag missing required fields, incorrect icon sizes, absent maskable icons, and any mismatch between start_url and the actual app root.
