apk-analyzer: Agent for Claude Code

.claude/agents/bug-reviewer.md

bug-reviewer is an agent for Claude Code from MartinStyk/apk-analyzer. It costs 59 tokens per session (952 once invoked), scanned A, original, GPL-3.0.

A read-only reviewer that checks Kotlin and Android code changes for logic bugs. It returns findings as structured JSON without modifying the code.

In plain words
What is it for?
Use it to inspect Kotlin or Android diffs for null-safety problems, off-by-one errors, wrong arguments, broken control flow, race conditions, resource leaks, and behavior that conflicts with a function's name.
Why use it?
It can catch mistakes that compile successfully but behave incorrectly, before they reach users. Because it reviews only the diff, developers can focus on newly introduced changes.

Agent for Claude Code

This is MartinStyk/apk-analyzer's own configuration. It tells Claude Code how to work on apk-analyzer itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything apk-analyzer configures →

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-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 2mo 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.

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.
