Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00040 | $0.02402 |
| Opus 5 | $0.00020 | $0.01201 |
| Sonnet 5 | $0.00008 | $0.00480 |
| Haiku 4.5 | $0.00004 | $0.00240 |
Grade A, and why
flutter-app-config scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Flutter App Configuration
Overview
Changing a Flutter app's name, bundle identifier, or package name requires modifying multiple platform-specific files. A missed file causes build failures or store rejection. This skill covers every file that needs updating on both iOS and Android.
When to Use
- User wants to change the app display name (what appears under the icon)
- User wants to change the iOS bundle identifier (e.g.,
com.company.appName) - User wants to change the Android application ID / package name (e.g.,
com.company.app_name) - User is preparing an app for release and needs correct identifiers
- User is cloning/forking a project and needs to rebrand it
- NOT for changing the Dart package name in
pubspec.yamlalone (that only affects Dart imports)
Quick Reference
| What to Change | iOS Files | Android Files |
|---|---|---|
| Display name | ios/Runner/Info.plist → CFBundleDisplayName, CFBundleName |
android/app/src/main/AndroidManifest.xml → android:label |
| Bundle ID / App ID | ios/Runner.xcodeproj/project.pbxproj → PRODUCT_BUNDLE_IDENTIFIER |
android/app/build.gradle → applicationId (or namespace in newer Gradle) |
| Package name (Android) | N/A | AndroidManifest.xml → package, Kotlin/Java directory structure, build.gradle → namespace |
Changing the App Display Name
The display name is what users see under the app icon on their home screen.
iOS
Edit ios/Runner/Info.plist:
<key>CFBundleDisplayName</key>
<string>My App Name</string>
<key>CFBundleName</key>
<string>My App Name</string>
CFBundleDisplayName— the name shown on the home screen (primary)CFBundleName— short bundle name, used in places where space is limited (max 15 characters recommended)- If
CFBundleDisplayNameis not present, iOS falls back toCFBundleName
Android
Edit android/app/src/main/AndroidManifest.xml:
<application
android:label="My App Name"
...>
The android:label attribute on the <application> tag sets the app name displayed on the launcher.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

flutter-app-config is a skill published in the GitHub repository nylo-core/claude-code (4 stars, last pushed 4mo ago), licensed MIT. It adds 40 tokens to every session and 2,402 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
