plugins/lisa-expo-copilot/skills/add-app-clip/SKILL.md
Add an iOS App Clip target to an Expo app. Use when the user mentions App Clip, AASA, apple-app-site-association, appclips, smart app banner, or wants to ship a lightweight iOS Clip invoked from a URL alongside their parent app.
npx skillsauth add codyswanngt/lisa add-app-clipInstall this skill globally with one command. Works with Claude Code, Cursor, and Windsurf.

Adds an iOS App Clip target to an Expo project. The Clip lives in targets/clip/, ships alongside the parent app, and is invoked from a URL on the app's domain via an Apple App Site Association (AASA) file.
The parent app's bundle ID becomes com.<username>.<app-name> and the Clip's is automatically derived as <parent>.clip (e.g. com.bacon.may20.clip).
bundleIdentifier and appleTeamIdbun create target warns if these are missing. Add to app.json:
{
"expo": {
"ios": {
"bundleIdentifier": "com.<username>.<app-name>",
"appleTeamId": "XX57RJ5UTD"
}
}
}
bun create target clip
This installs @bacons/apple-targets, adds it to the plugins array in app.json, and writes:
targets/clip/expo-target.config.js — the target's config plugintargets/clip/Info.plist — Clip Info.plisttargets/clip/AppDelegate.swift, Assets.xcassets, etc.Pick a good icon or reuse the existing one defined in the app — check it with bunx expo config under the icon or ios.icon key.
The parent app and the Clip each need the Associated Domains entitlement pointing at the domain that hosts the AASA file.
In app.json, add both applinks: (parent) and appclips: (Clip invocation) entries:
{
"expo": {
"ios": {
"associatedDomains": [
"applinks:may20.expo.app",
"appclips:may20.expo.app"
]
}
}
}
In targets/clip/expo-target.config.js, declare the Clip's entitlement:
/** @type {import('@bacons/apple-targets/app.plugin').ConfigFunction} */
module.exports = (config) => ({
type: "clip",
icon: "https://github.com/expo.png",
entitlements: {
"com.apple.developer.associated-domains": ["appclips:may20.expo.app"],
},
});
If you skip this,
expo prebuildwill print:Apple App Clip may require the associated domains entitlement but none were found.
bunx setup-safari
This logs in to the Apple Developer account, registers com.bacon.may20, creates the App Store Connect entry, and prints:
apple-app-site-association JSON<meta name="apple-itunes-app"> tag with the iTunes app idApp Clips are invoked when iOS fetches https://<your-domain>/.well-known/apple-app-site-association and finds a matching appclips entry.
mkdir -p public/.well-known
touch public/.well-known/apple-app-site-association
Paste the JSON setup-safari printed, but add an appclips block for the Clip's full app ID (<TeamID>.<ClipBundleID>). The output of setup-safari only covers the parent app:
{
"applinks": {
"details": [
{
"appIDs": ["XX57RJ5UTD.com.bacon.may20"],
"components": [{ "/": "*", "comment": "Matches all routes" }]
}
]
},
"appclips": {
"apps": ["XX57RJ5UTD.com.bacon.may20.clip"]
},
"activitycontinuation": {
"apps": ["XX57RJ5UTD.com.bacon.may20"]
},
"webcredentials": {
"apps": ["XX57RJ5UTD.com.bacon.may20"]
}
}
Notes:
Content-Type requirements beyond being served as-is. Expo Router static export serves files in public/ verbatim.appclips block is what lets a URL on the domain launch the Clip.webcredentials is used for sharing credentials between the website, parent app, and the App Clip.activitycontinuation is optional and used for sharing the link between mobile and desktop. Must be used with Head from expo-router — see https://docs.expo.dev/router/advanced/apple-handoff/Create src/app/+html.tsx (Expo Router's HTML shell) and add the tag from setup-safari. Create the versioned template if it doesn't exist:
bunx expo customize src/app/+html.tsx
Add the meta tag to the <head>:
import { ScrollViewStyleReset } from "expo-router/html";
export default function Root({ children }: { children: React.ReactNode }) {
return (
<html lang="en">
<head>
<meta charSet="utf-8" />
<meta httpEquiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="apple-itunes-app" content="app-id=6771566491" />
<ScrollViewStyleReset />
</head>
<body>{children}</body>
</html>
);
}
To make the website show the App Clip card instead of the install card, use:
<meta
name="apple-itunes-app"
content="app-id=6771566491, app-clip-bundle-id=com.bacon.may20.clip, app-clip-display=card"
/>
The AASA file must be live before iOS will trust the association. Use EAS Hosting:
bunx expo export -p web
eas deploy --prod
This publishes the site (including /.well-known/apple-app-site-association) at https://<slug>.expo.app. Verify:
curl https://may20.expo.app/.well-known/apple-app-site-association
Inspect the parent app's permissions after prebuild:
npx expo config --type introspect
Look at the infoPlist object — mirror the permission keys in the App Clip's Info.plist so matching APIs can be used from the Clip.
Set deploymentTarget: "17.6" in the Clip's target config — App Clips have a higher minimum size limit in iOS 17.6.
If the app uses push notifications or location services, add to the App Clip's Info.plist to request the necessary permissions:
<key>NSAppClip</key>
<dict>
<key>NSAppClipRequestEphemeralUserNotification</key>
<false/>
<key>NSAppClipRequestLocationConfirmation</key>
<true/>
</dict>
bunx testflight
This will:
eas.json if missing.Enabled: Associated Domains for the Clip target.Pull existing App Store metadata to local:
eas metadata:pull
Add apple.appClip to store.config.json. Up to 3 invocation URLs can launch the Clip from a web page:
{
"configVersion": 0,
"apple": {
"appClip": {
"defaultExperience": {
"action": "PLAY",
"releaseWithAppStoreVersion": true,
"reviewDetail": {
"invocationUrls": ["https://may20.expo.app/", null, null]
},
"info": {
"en-US": {
"subtitle": "Instantly native with Expo",
"headerImage": "store/apple/app-clip/en-US/asc-app-clip.png"
}
}
}
}
}
}
The headerImage must be a 1800x1200 PNG with no opacity.
Push back to the store:
eas metadata:push
Apple's recommended App Clip metadata guidelines: https://sosumi.ai/documentation/appclip/configuring-the-launch-experience-of-your-app-clip
com.bacon.may20com.bacon.may20.clip, lives in targets/clip/https://may20.expo.app/.well-known/apple-app-site-associationOnce Apple invokes the Clip from a URL on the domain, iOS opens targets/clip/'s entry point which loads the React Native app.
To let JS detect when it's running inside an App Clip and present an install prompt for the full app, create a local Expo module (bunx create-expo-module --local) that exposes navigator.appClip.prompt().
See ./references/native-module.md for the Swift module, TypeScript interface, and usage.
development
Prepare a machine — a fresh laptop or a throwaway container — to run coding agents, before any repository exists. Detects which of Lisa's supported agents (Claude Code, Codex, Cursor, OpenCode, Antigravity, Copilot) are already installed, asks which credential manager the machine uses (Bitwarden, 1Password, Doppler, Vault, AWS, or none), and installs only what is missing, each by its vendor's own preferred method. Idempotent, headless by default, and emits a Dockerfile for a spin-up/spin-down environment. Run it on a new machine, in a container, or before cloning anything.
tools
Provision and verify a remote execution environment for a host project — Codex Cloud today, other remote surfaces as they are added. Generates a repository-owned setup script that installs the declared toolchain, materializes secrets through lisa-secrets-access, and runs the project's own hook. Provisions by API where one exists, by driving the vendor console where one does not, and by emitting exact config otherwise — then proves the result with the same read-back regardless of which tier did the work. Use before dispatching any work with executionEnv.
tools
Bring a developer's machine in line with the toolchain the project declares. Reports every tool in remoteEnv.tools that is missing, outdated, or unpinned for this platform, and installs the missing ones into ~/.local/bin from the same pinned, checksummed entries the remote surfaces use — but only when asked. Same manifest, same pins, same installers as lisa-setup-remote-env; what differs is consent and that the pin is a floor rather than an equality. Run it on a fresh checkout, after a manifest change, or when a tool fails at the moment of use.
tools
Route one unit of work to a remote execution surface. Reads the executionEnv parameter (local by default, codex-cloud or claude-web today), verifies the environment is provisioned and bound to this repository, submits a thin skill invocation, records the task identifier to .lisa/remote-dispatch.json, and exits without polling. Routing only — the remote runs the identical skill from the identical repository. Composable and inline: other skills invoke it via the Skill tool rather than users calling it directly.
