v0.5.0 — Test Quality Review

What's New

Mode 4: Test Quality Review — a dedicated test suite health audit powered by four classic testing books.

New Features

• /brooks-lint:brooks-test — full test quality audit across six test-space decay risks
• PR Review Step 7: Quick Test Check — lightweight three-signal test scan automatically appended to every PR review (Coverage Illusion, Mock Abuse, Test Obscurity)
• Six test decay risks mirroring the six production decay risks:
  • T1: Test Obscurity — Assertion Roulette, Mystery Guest, ambiguous test names
  • T2: Test Brittleness — Eager Test, over-specified mocks, implementation-coupled tests
  • T3: Test Duplication — Lazy Test, copy-pasted setup, redundant cross-layer coverage
  • T4: Mock Abuse — 3+ mocks, mock-call-only assertions, test-only production methods
  • T5: Coverage Illusion — happy-path only, untested error paths, legacy code being modified without tests
  • T6: Architecture Mismatch — inverted test pyramid, no seam points, missing characterization tests

Source Books Added

• Gerard Meszaros — xUnit Test Patterns (2007)
• Roy Osherove — The Art of Unit Testing (2009, 3rd ed. 2023)
• Google Engineering — How Google Tests Software (2012)
• Michael Feathers — Working Effectively with Legacy Code (2004)

Also Fixed

• hooks/session-start: /brooks-test now listed in the session context — Mode 4 is discoverable without reading the README
• .claude-plugin/plugin.json: version and description updated to reflect v0.5 capability set
• evals/evals.json: benchmark now covers all four modes (was Mode 1–3 only)

brooks-lint now covers 10 classic engineering books across four analysis modes. Every finding still follows the Iron Law: Symptom → Source → Consequence → Remedy.
