subwave: Skill for Claude Code

.claude/skills/subwave-app-android-release/SKILL.md

subwave-app-android-release is a skill for Claude Code from perminder-klair/subwave. It costs 0 tokens per session (3,637 once invoked), scanned C, original, MIT.

An Android release workflow for the SUB/WAVE mobile app, which is built with Expo. It creates either a Google Play App Bundle or an APK that testers can install directly.

In plain words
What is it for?
Use it to build a new SUB/WAVE Android version in the cloud, prepare it for manual upload to Google Play, or give testers an install link and QR code. It is for distributed builds, not running the app over USB on your own phone.
Why use it?
It organizes the different ways to ship an Android update, so a store release is not confused with a quick test build. It also explains when an over-the-air JavaScript update may avoid a new binary.

About the project

Subwave is an internet radio station where an AI DJ selects music and speaks between tracks for every listener at once. Listeners can request music in plain language, while operators manage the queue, schedule, DJ personas, and station activity. Its catalogue entries define skills and workflows for operating the station.

Token cost

What it costs to keep this loaded

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.

Security

Grade C, and why

subwave-app-android-release scanned grade C with 1 finding 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

SUB/WAVE Android release → Play Store / testers

The app is live in production on the Google Play Store. There are two ways to ship a fresh Android binary, and which you want depends on the audience:

  • Play Store release (production profile) — builds a signed .aab App Bundle on EAS. You then upload it to the Play Console by hand (submission is manual — see the Play Store section). This is how real users get the update.
  • Quick sideload test (preview profile) — builds an APK and returns an install link + QR any Android phone can tap, no Google account involved. Good for handing a build to a trusted tester fast, outside the Play Store machinery.

Either way EAS generates+stores the signing keystore for you. Ask which one the user wants if it's ambiguous — "release"/"ship to the store" → production .aab; "send to a tester"/"install link" → preview APK.

For a phone you can physically plug in (USB/adb, live hot-reload), use the local subwave-app-android skill instead.

First: does this even need a new build? (OTA)

The app ships expo-updates (OTA). If the change is JS/TS only — components, hooks, styles, copy, logic, Metro-bundled assets — you do not need a new APK/AAB. Push it over-the-air to the binaries already installed:

cd "$APP"
eas update --channel preview --message "fix: …"      # tester (internal-APK) builds
eas update --channel production --message "fix: …"    # Play builds

It reaches every installed build whose runtime version (fingerprint) matches. Testers see it on the next cold start (it fetches in the background; fallbackToCacheTimeout: 0 keeps launch instant, so kill + relaunch twice to confirm it applied).

A new build is only required when native inputs changed: a dependency add/upgrade, anything under app/patches/, a config plugin, or app.json's android/plugins sections. The fingerprint policy guarantees an OTA can't land on a binary with mismatched native code. Rule of thumb: ran npx expo install or touched patches/? → build. Otherwise → OTA. Full decision table: app/docs/RELEASE.md.

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.
