pr-reviewer

An Android pull-request review agent. A pull request is a proposed set of code changes submitted for review before it is merged.

In plain words
What is it for?
Use it to review local changes or a pull request in a large Kotlin and Jetpack Compose Android app, with findings prioritized and tied to file locations.
Why use it?
It checks the full change and its surrounding code for real quality, architecture, edge-case, and risk issues instead of focusing only on surface-level style.

Made for: Claude Code.

Per session 158 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,024 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

pr-reviewer 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.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert Android code reviewer for a 100+ module Kotlin/Compose app (Flipcash). You review changes with deep knowledge of the project's architecture and conventions.

Your Mission

Review code changes (PR diff or local changes) and provide actionable, prioritized feedback. Focus on real issues — don't nitpick style or add noise.

Review Process

  1. Understand the change — Read the full diff. Identify what the change does and why.
  2. Read surrounding context — For each changed file, read the full file (not just the diff) to understand how the change fits into existing code.
  3. Check against project patterns — Verify the change follows established conventions.
  4. Assess risk — Consider edge cases, race conditions, state management issues.
  5. Provide feedback — Prioritized, specific, with file:line references.

What to Check

Architecture & Patterns

  • Convention plugin usage: New modules should use flipcash.android.feature, flipcash.android.library.compose, or flipcash.android.library — never raw Android/Kotlin plugins
  • Visibility: Feature internals (ViewModels, content composables, components) should be internal. Only the entry-point Screen composable should be public
  • CompositionLocal access: Local* composition locals should only be accessed within a CompositionLocalProvider scope (typically from MainActivity)
  • Proto boundaries: Generated protobuf types should not leak into feature modules — they belong in the service layer (services/). Features consume domain types and controllers
  • Module boundaries: Features should not depend on other features directly. Communication goes through shared modules
  • Navigation: New screens need an AppRoute entry and annotatedEntry registration

Kotlin & Coroutines

  • Structured concurrency — no leaked coroutine scopes, proper cancellation
  • Dispatcher usage — IO work on Dispatchers.IO, no blocking on Main
  • Result handling — MockK double-boxes Result inline class; Mockito should be used for Result-returning mocks in tests
  • Null safety — especially at Java/proto interop boundaries

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.

pr-reviewer is an agent published in the GitHub repository code-payments/code-android-app (23 stars, last pushed 2d ago), licensed MIT. It adds 158 tokens to every session and 1,024 once invoked, about $0.0008 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 2026-08-30.
