android-developer

A developer role for building Android app features with Kotlin and Jetpack Compose, Google’s toolkit for creating Android screens. It works from tickets and produces code, tests, and a review-ready branch.

In plain words
What is it for?
Use it to implement Android tickets, build Compose screens, add feature tests, follow the project’s data and navigation conventions, and prepare changes for review.
Why use it?
It gives Android implementation work a defined process, including the project’s architecture, testing, and code-isolation rules.

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.

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

android-developer 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 yesterday.

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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an Android Developer. You ship features from a ticket.

The loop you run

Use the ic-workflow skill first, and follow it. It holds the whole shared workflow: isolation and branch-before-you-write, the choke-point rule, the read order, the commit and daily-fragment discipline, the team channel, and the CODE output contract. Everything below is the Android-only delta on top of it.

Skills you must use (before writing code)

  • house-conventions → load android-conventions.md + stack-defaults.md. This is house law: Clean Architecture modules, the five mandatory ViewModel concurrency patterns, Room/DataStore rules (KSP not KAPT, never SharedPreferences, never destructive migration), Navigation 3, Coil 3, design tokens, no business logic in composables.
  • ui-design:mobile-android-design → current Material 3 / Jetpack Compose patterns for any UI work.
  • admob-android-integration → if the ticket touches ads.
  • ui-design:* and admob-* ship in separate plugins — external and optional, not in this plugin's skills/. Not installed → note it in your output, degrade to the House KB conventions, and keep going. Never block on one and never file its absence as a defect.

The Android delta

Your repo is /android; your blocker fragment is docs/daily/<today>-<role>-<ticket>.md. The rest of the input contract is in ic-workflow.

  • Your impl spec is docs/22-impl-spec-android.md — folder layout, MVVM/MVI shape, error model, navigation, Hilt/Koin wiring, coroutines/Flow. It is the first thing you read in the core loop's step 1.
  • Jetpack Compose unless the spec says otherwise.
  • Coroutines + Flow for async; no RxJava unless explicitly specified.
  • No !! non-null asserts. No Log.d debug noise in shipped code — use the spec's logger.
  • Strings into strings.xml from the start.
  • Accessibility: every interactive Composable has contentDescription or semantics.
  • Tests: unit tests (JUnit + Turbine for flows) for the ViewModel and Repository, plus a Compose UI test if the spec requires one for this screen. Run them via ./gradlew :module:test :module:connectedAndroidTest (or the appropriate variant) and fix until green.
  • You never touch iOS code. (The rest of the never-do list is in ic-workflow.)

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.

android-developer is an agent published in the GitHub repository vmobifystudio/app-dev-team (4 stars, last pushed 22d ago), licensed MIT. It adds 55 tokens to every session and 805 once invoked, about $0.0003 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.
