What Brooks Test does

Brooks Test reviews an existing test suite for structural quality problems—brittleness, mock abuse, coverage illusions, slow execution, and poor readability—using principles from classic engineering books. Use it when tests keep breaking, take forever, or pass while bugs reach production.

Brooks Test is cataloged under Quality on DirSkills. Brooks Test comes from a repository tagged agent-skills, ai-code-review, architecture-review, auto-fix and claude-code.

README

From the original repository

Brooks-Lint — Test Quality Review

Setup

Read in order:

../_shared/common.md — Iron Law, Project Config, Report Template, Health Score
../_shared/source-coverage.md — book coverage, exceptions, tradeoffs
../_shared/test-decay-risks.md — test-space symptom definitions and sources
test-guide.md (this directory) — the test quality review framework

Process

Scope: if the user did not share test files or point to a test directory, apply Auto Scope Detection (../_shared/common.md) first.

Build the test suite map (guide's "Before You Start" section)
Scan for each test decay risk in the order specified (Steps 1–4 of the guide)
Apply the Iron Law and output using the Report Template (Step 5 of the guide)
