brooks-test
Review test-suite quality using established testing literature; identify brittleness, mock abuse, unclear fixtures, weak assertions, slow feedback, and maintenance risks.
Why this skill is useful
Provides a structured framework for diagnosing test suite issues based on classic engineering literature, which the AI wouldn't reliably generate on its own.

What this skill does
Brooks-Lint — Test Quality Review When to Use Use this skill when you need test quality review drawing on twelve classic engineering books — with primary focus on xUnit Test Patterns, The Art of Unit Testing, How Google Tests Software, and Working Effectively with Legacy Code — that diagnoses structural problems in an existing test suite: brittleness, mock... Setup 1. Read ../shared/common.md for the Iron Law, Project Config, Report Template, and Health Score rules 2. Read ../shared/source-coverage.md for book-level coverage, exceptions, and tradeoffs 3. Read ../shared/test-decay-risks.md for test-space symptom definitions and source attributions 4. Read test-guide.md in this directory for the test quality review framework Process If the user has not shared test files or pointed to a test directory: apply Auto Scope Detection from ../shared/common.md to determine the review scope before proceeding. 1. Build the test suite map (guide's "Before You Start" section) 2. Scan for each test decay risk in the order specified (Steps 1–4 of the guide) 3. Apply the Iron Law and output using the Report Template (Step 5 of the guide) Mode line in report: Test Quality Review Limitations Use this skill only when the task clearly matches its upstream source and local project context. Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes. Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
