java-android-workflow

java-android-workflow is a skill for Claude Code from gaelic-ghost/socket. It costs 58 tokens per session (912 once invoked), scanned A, original, Apache-2.0.

A workflow for maintaining Android apps and libraries written in Java, including how Java and Kotlin code call each other.

In plain words
What is it for?
Use it when changing Java source sets, AndroidX code, annotations, nullability, method signatures, generated bytecode expectations, tests, or lint settings.
Why use it?
It helps preserve Java-only projects, keep public APIs compatible, and avoid errors at boundaries between Java, Kotlin, and generated code.

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 A, and why

java-android-workflow 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.

Java Android Workflow

Purpose

Preserve Java Android codebases and make Kotlin/Java boundaries explicit when Android modules are mixed-language.

The practical decision is whether to stay Java-only, add Kotlin interop carefully, or route implementation to Kotlin-first guidance without forcing a migration.

Source Check

Use repo-local Java, Kotlin, Gradle, and Android files first. Use Dash.app Java or Gradle docsets opportunistically for installed local reference. Use official documentation as authority for Android-specific APIs, Kotlin Java interop, AndroidX behavior, and version-sensitive rules:

Translate documentation into concrete API, annotation, source-set, or validation choices.

Inspection Workflow

  1. Inspect source ownership:
    • src/main/java
    • src/main/kotlin
    • generated sources
    • public Android library APIs
    • Java callers of Kotlin code and Kotlin callers of Java code
  2. Identify interop boundaries:
    • nullability annotations
    • @JvmName, @JvmOverloads, @JvmStatic, @JvmField, or @Throws
    • SAM conversions and functional interfaces
    • checked exceptions and callback APIs
    • data classes, sealed classes, objects, companion objects, and generated bytecode as seen from Java
  3. Preserve Java-only projects:
    • keep Java examples and implementation idiomatic for the existing codebase
    • do not add Kotlin plugin or Kotlin sources without user approval
    • keep AndroidX and Java language level aligned with repo configuration
  4. Maintain mixed projects:
    • keep public APIs friendly from both languages when they already cross the boundary
    • use annotations for nullability and threading where the repo already does
    • keep generated binding, Room, Hilt, KSP, KAPT, or annotation processing behavior explicit
  5. Validate:
    • compile or assemble the affected module
    • run unit tests that exercise the Java/Kotlin boundary
    • run lint when annotations, threading, lifecycle, resources, or Android APIs changed

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.
