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 5.1 | $0.00052 | $0.01492 |
| Opus 5.5 | $0.00021 | $0.00597 |
| Sonnet 5.5 | $0.00010 | $0.00298 |
| Haiku 4.5 | $0.00005 | $0.00149 |
Grade A, and why
release 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 200 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Release - App Store & Play Store Preparation
Prepare Flutter apps for production release. Handles signing, icons, splash screens, and store setup.
When to Use This Skill
- Setting up Android signing (keystore, key.properties)
- Configuring iOS signing (certificates, provisioning profiles)
- Creating app icons for iOS and Android
- Setting up splash screens
- Preparing for App Store Connect or Google Play Console
- Verifying release readiness
- Building release APK/AAB/IPA
Manual vs CI/CD Release
| Approach | Use When | Signing |
|---|---|---|
| Manual (this skill) | First release, small team | Local keystore, Xcode |
CI/CD (/ci-cd) |
Regular releases, teams | GitHub Secrets, Fastlane |
Recommendation: Start with manual release. Set up CI/CD when you need automation.
Quick Reference
Platform Requirements
| Platform | Signing | Store | Build Command |
|---|---|---|---|
| Android | Keystore + key.properties | Play Console | flutter build appbundle --release |
| iOS | Xcode Team + Provisioning | App Store Connect | flutter build ipa --release |
Commands
# Audit release readiness
dart run .claude/skills/release/scripts/check.dart
# Build release
flutter build appbundle --release # Android
flutter build ipa --release # iOS
| check.dart Option | Purpose |
|---|---|
--platform android/ios |
Audit specific platform only |
--fix |
Auto-fix .gitignore patterns |
--checklist |
Generate markdown checklist |
--capabilities |
Detect required iOS capabilities |
--keytool-command |
Generate keystore creation command |
Workflow
1. Audit Current State
dart run .claude/skills/release/scripts/check.dart
Identifies: Missing keystore, unsigned iOS, missing icons, uncommitted .env files.
2. Create Assets
See assets-guide.md:
- App icon: 1024x1024 PNG (no transparency for iOS)
- Splash screen: Configure flutter_native_splash
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

release is a skill published in the GitHub repository launch52-ai/flutter-template (2 stars, last pushed 7mo ago), licensed MIT. It adds 52 tokens to every session and 1,492 once invoked, about $0.0002 per session on Opus 5.5. 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.
