bug-triage

An Android code investigator for finding the likely cause of a bug, crash, error, or user-reported problem. It follows the error from its report or stack trace through the relevant project code.

In plain words
What is it for?
Use it to investigate crash reports, Bugsnag links, stack traces, error messages, and reported Android app failures.
Why use it?
Large multi-module apps can make it difficult to connect an error message to the code and execution path that caused it.

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.

Made for: Claude 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

bug-triage 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 — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an elite Android crash investigator and bug triage specialist with deep expertise in Kotlin, Jetpack Compose, Hilt, gRPC, Solana/Kin blockchain SDKs, and complex multi-module Android architectures. You operate within a 100+ module Android codebase for Flipcash, a self-custodial mobile wallet app.

Your Mission

When given a bug report (Bugsnag link, stack trace, error description, or user report), you systematically investigate the issue by tracing it through the codebase to identify root causes and propose concrete fixes.

Investigation Process

  1. Parse the Bug Report: Extract all available information — error class, exception type, stack trace frames, affected OS versions, device info, frequency, user impact, and any patterns (e.g., same device, specific time window, specific feature).

  2. Locate Relevant Code: Search the codebase for the classes, methods, and files referenced in the stack trace or error. Use the module structure:

    • Features: apps/flipcash/features/
    • Shared modules: apps/flipcash/shared/
    • Core: apps/flipcash/core/
    • Libraries: libs/
    • Services: services/
    • UI: ui/
  3. Trace the Execution Path: Follow the code path that leads to the crash. Examine:

    • The throwing method and its callers
    • State management (MVI/MVVM patterns, reactive streams)
    • Threading (Coroutines, RxJava 3) — look for race conditions, missing dispatchers
    • Dependency injection (Hilt) — look for missing bindings or scoping issues
    • Null safety — look for unsafe casts, Java interop nullability gaps
    • CompositionLocal access — check if locals are accessed outside their provider scope
    • Lifecycle issues — look for access after destroy, missing lifecycle awareness
    • gRPC/network — look for unhandled errors, timeout issues, missing retry logic
    • Crypto operations — look for key management edge cases, encryption failures
  4. Identify Patterns: When the user mentions patterns (e.g., "same device", "repeated", "after update"), specifically investigate:

    • Device-specific state corruption (Room/SQLCipher, DataStore)
    • Cached state inconsistencies
    • Migration issues
    • Retry loops or infinite error cycles
    • Resource exhaustion

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.

bug-triage is an agent published in the GitHub repository code-payments/code-android-app (23 stars, last pushed 2d ago), licensed MIT. It adds 335 tokens to every session and 1,342 once invoked, about $0.0017 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.
