Installation

A skill is a folder with a SKILL.md file. Pick your agent and run the commands in a terminal (macOS, Linux or Git Bash on Windows) from your project root.

Copy the prompt into Claude, Codex or another assistant: it will review the skill and install it for you.

Install the “apple-web-app” skill from mozgi.io (https://mozgi.io/skills/joe-bell-apple-web-app/) for me.

1. Download the archive: https://mozgi.io/skills/joe-bell-apple-web-app/download
   If it fails, take the skill folder from the source: https://github.com/joe-bell/skills/tree/main/skills/apple-web-app
2. Read SKILL.md and the other files. Check the skill is safe: no hidden commands, no sending data elsewhere, no scripts doing something other than described. If anything looks suspicious, stop and tell me.
3. Put the “apple-web-app” folder into your agent's skills folder: .claude/skills/ for Claude Code, .agents/skills/ for Codex, .cursor/skills/ for Cursor, .gemini/skills/ for Gemini CLI. Inside the project if we are in one, otherwise in the home folder (~/.claude/skills/ etc.).
4. Make sure <skills folder>/apple-web-app/SKILL.md exists.
5. Briefly tell me what this skill does and offer to try it on my task.

If you cannot do a step yourself, tell me what to click or type.

git clone --depth 1 --branch main https://github.com/joe-bell/skills.git /tmp/skills
mkdir -p .claude/skills
cp -r /tmp/skills/skills/apple-web-app .claude/skills/apple-web-app

Restart Claude Code — the skill appears in the list; call it manually with /apple-web-app. For all projects use ~/.claude/skills.

git clone --depth 1 --branch main https://github.com/joe-bell/skills.git /tmp/skills
mkdir -p .agents/skills
cp -r /tmp/skills/skills/apple-web-app .agents/skills/apple-web-app

Codex looks for skills in .agents/skills from the current folder up to the repo root; call one with /skills or $apple-web-app. For all projects use ~/.agents/skills.

git clone --depth 1 --branch main https://github.com/joe-bell/skills.git /tmp/skills
mkdir -p .cursor/skills
cp -r /tmp/skills/skills/apple-web-app .cursor/skills/apple-web-app

Cursor picks the skill up on start; call it with “/” in Agent chat. Cursor also reads .claude/skills and .agents/skills. For all projects use ~/.cursor/skills.

git clone --depth 1 --branch main https://github.com/joe-bell/skills.git /tmp/skills
mkdir -p .gemini/skills
cp -r /tmp/skills/skills/apple-web-app .gemini/skills/apple-web-app

Gemini CLI offers to activate the skill when a task matches — you approve it. For all projects use ~/.gemini/skills.

Websites and web apps on Apple devices

Choose the scope

Use this skill to give any website or web app a good experience on iPhone and

iPad, in Safari itself or installed to the Home Screen, and for macOS Safari Add

to Dock UI. Service workers, offline caching, background sync and push

implementation belong elsewhere.

Infer the platform, requested outcome and existing architecture from the task

and project. Ask only when a missing detail materially changes the solution.

Apply guidance relevant to that platform and symptom. Preserve working layout,

authentication and product choices unless they cause the requested issue. User

instructions take precedence over this skill's defaults.

Implement or debug: read the matching reference, make the focused change,

and check its affected behavior and likely regressions.

Audit: use the

conformance checklist ↗ for all

applicable recommendations. Report findings before modifying the site unless

the user has also asked for fixes.

Maintain this skill: follow maintenance.md ↗.

Ordinary site work does not require a skill update or upstream handoff.

Read only relevant references

| Platform or problem | Reference |

| Mac Dock icons, title bar, display mode, navigation or storage | macos-add-to-dock.md ↗ |

| iOS head tags, manifest integration or icons | head-and-icons.md ↗ |

| iOS safe areas, scroll roots, cold launch or touch styling | layout-and-touch.md ↗ |

| iOS status bar, Safari bar tinting or light/dark appearance | theme-color-and-status-bar.md ↗ |

| iOS overlays, full-screen dims, keyboard or scroll locking | overlays-and-keyboard.md ↗ |

| iOS startup images | splash-screens.md ↗; read ios-devices.md ↗ when generating or checking sizes |

| A suspected iOS release regression | ios-26-notes.md ↗ |

| Translating a relevant recipe into existing Tailwind v4 code | tailwind-css-v4.md ↗ |

A Mac-only task starts with the Mac reference. Do not generate iOS startup

images or add iOS safe-area work for it. Source: WebKit; Joe Bell, as recorded

in macos-add-to-dock.md ↗.

Essential constraints and evidence

A zero safe-area inset is valid. Keep controls usable without assuming a

positive top inset; never hide an app waiting for one. Source: Joe Bell;

WebKit 301994, in sources.md ↗.

Preserve pinch zoom and text selection. Scope touch suppression to controls or

media with an intentional replacement interaction. Source: Firtman; React

Spectrum, in sources.md ↗.

Installed apps that hide browser controls need usable navigation back or out.

Source: Firtman; Steiner, in install-ux.md ↗.

Treat documented behavior, device observations, community workarounds and

optional design preferences distinctly. Apply a version-specific workaround only

when its symptom and environment match. A reported fix or bug status is

historical evidence, not a guarantee for every later release. Read the cited

source or recheck the target build when a changing fact determines the fix.

Preserve existing test dates; do not relabel inherited findings as newly tested.

Source provenance and retained observations:

sources.md ↗.

Verify the requested outcome

Use relevant entries from the

conformance checklist ↗. Check generated

HTML, CSS, image dimensions and unauthenticated asset delivery where applicable.

Device-specific appearance needs observation on the target installed app on a

real device. Simulator or desktop emulation alone does not establish safe-area

timing, status-bar sampling or splash selection. Source: Joe Bell, in

sources.md ↗.

When hardware or authenticated runtime access is unavailable, complete the

independent checks and mark the remaining claims Unverified. State what was

checked, what failed, and the specific remaining device check. Do not expand a

focused fix into a full device matrix. Stop after the relevant checks pass

unless a failure or new change warrants more verification.

Frequently asked questions

What does the apple-web-app skill do?

Implement, debug, or audit iPhone/iPad Add to Home Screen and macOS Safari Add to Dock web app UI: safe areas, status bar, theme color, manifest, icons, splash screens, and installed navigation.

How do I install apple-web-app?

Open the “Installation” block on this page and pick your agent — Claude Code, Codex, Cursor or Gemini CLI — for ready-made commands that copy the skill folder to the right place. Or copy the prompt from the “Via assistant” tab and let the assistant review and install the skill.

Which AI models work with apple-web-app?

Skills are plain Markdown instructions (the Agent Skills format), so apple-web-app works with any agent that reads SKILL.md: Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and more. The model loads the instructions only when a task matches the skill's description.

Is apple-web-app free?

The skill is published openly by joe-bell under the MIT license. The skill itself costs nothing — you only pay your AI provider for the tokens you use.

Is it safe to install skills?

A skill is a set of instructions your agent will follow, so read SKILL.md and its companion files before installing. Scripts in the skill folder only run if your agent runs them — keep an eye on what it does and do not grant unnecessary permissions.

How is a skill different from an MCP server or a plugin?

An MCP server or plugin gives the model new tools — code that runs and returns a result. A skill gives it knowledge and process: how to approach a task, which steps to follow and what good output looks like. It needs no server or API key.
