Why it matters

Run a systematic adversarial QA pass on any codebase to find logic errors, security holes, edge cases, and cross-file inconsistencies that AI code generators miss, producing a severity-triaged bug report that tracks issues over time.

Outcomes

What it gets done

01

Trace data flows across file boundaries to catch API mismatches and cross-file consistency bugs

02

Simulate hostile edge cases like null inputs, empty arrays, and race conditions against every code path

03

Classify findings by severity (Critical/Intermediate/Normal) with exact file:line references and fix suggestions

04

Maintain a running bugs.md history that re-verifies old issues and appends new findings on each audit

Overview

Bugs Are Annoying

Bugs Are Annoying runs a 7-phase adversarial QA process on any codebase, actively trying to break code instead of confirming it works. It checks every line against a comprehensive taxonomy covering logic errors, null safety, edge cases, concurrency issues, security holes, resource leaks, and cross-file consistency. It produces a structured bugs.md report with exact file:line references, severity classifications, and suggested fixes. Use this when you need a deep correctness audit of AI-generated code, before merging major changes, or when hunting elusive production bugs. Trigger it with phrases like "find bugs," "audit this code," or "is this code solid." It's designed for correctness verification, not style or formatting reviews.

What it does

Bugs Are Annoying is an adversarial QA pass for any codebase in any language. It exists to close the gap between code that looks finished and code that is actually correct. Instead of confirming code works, it actively tries to break it by checking every line against a comprehensive bug taxonomy covering logic errors, null safety, edge cases, concurrency issues, security holes, and cross-file consistency problems.

When to use - and when NOT to

Trigger this skill when you need a deep correctness audit: "find bugs," "audit this code/codebase," "run bug hunter," "check for errors," "find flaws," "review this for bugs," or "is this code solid." Use it after AI-generated code is produced, before merging major changes, or when debugging elusive production issues.

Do NOT use this for style reviews, formatting checks, or readability improvements. This skill explicitly ignores stylistic preferences and focuses only on correctness, security, and functional bugs.

Inputs and outputs

You provide the codebase scope (specific files, folders, or git diff). The skill asks for confirmation if scope is ambiguous to avoid blowing context on large repos. It automatically excludes generated directories (node_modules, vendor, dist, build) and minified files.

You receive a single bugs.md file at the project root with this exact structure:

### Bug Report - [project/scope name] - [date]

### Summary
- Critical: N open, N fixed
- Intermediate: N open, N fixed
- Normal: N open, N fixed

###  Critical

### BUG-001: [Short title]
- **File:** path/to/file.ext:line
- **Issue:** what is actually wrong
- **Trigger:** the exact input/sequence that causes it
- **Impact:** what breaks because of it
- **Suggested Fix:** described or sketched, not applied
- **Confidence:** *(omit if fully confirmed in-scope; include "Needs Verification" if it depends on code outside the audited scope)*
- **Status:** Open

###  Intermediate
...

###  Normal
...

###  Resolved
### BUG-0XX: [Title] - Fixed [date]
(kept for history, moved here once fixed)

Every bug gets an exact file:line reference, sequential ID, severity classification (Critical, Intermediate, Normal), and suggested fix. The skill never auto-fixes code - it only writes to bugs.md.

Who it's for

Developers working with AI coding assistants who need to verify generated code is actually correct, not just syntactically valid. Engineering teams conducting pre-merge audits on AI-assisted pull requests. Solo developers hunting down elusive bugs that passed initial review. Security-conscious teams needing adversarial review of authentication, input handling, and resource management code.

The skill runs a 7-phase process: scope determination, codebase mapping, static line-by-line pass, critical data path tracing, adversarial simulation with hostile inputs (null, empty arrays, max-length strings, concurrent calls), cross-reference checking for repeated mistakes, and severity triage. On re-runs, it maintains history by re-verifying existing bugs, moving fixed ones to Resolved, and appending new findings with continuing IDs.
