Language-agnostic testing principles including TDD, test quality, coverage standards, and test design patterns. Use when writing tests, designing test strategies, or reviewing test quality.

Language-agnostic coding principles for maintainability, readability, and quality. Use when implementing features, refactoring code, or reviewing code quality.

Technical decision criteria, anti-pattern detection, debugging techniques, and quality check workflow. Use when making technical decisions, detecting code smells, or performing quality assurance.

Technical decision criteria, anti-pattern detection, debugging techniques, and quality check workflow. Use when making technical decisions, detecting code smells, or performing quality assurance.

Executes implementation tasks through Todo, In Progress, To Review. Use when task needs coding with KISS/YAGNI. Not for test tasks.

Detects tests proving platform behavior instead of local product behavior. Use when auditing product-behavior focus.

Executes optimization hypotheses with keep/discard testing loop. Use when applying validated performance improvements.

Performs manual testing of Story AC via executable bash scripts in tests/manual/. Use when Story implementation needs hands-on AC verification.

Audits whether test results can be trusted: flakiness, isolation, real external dependencies, time/random/order dependency, and shared state. Use when auditing test trustworthiness.

Reviews task implementation for quality, code standards, and test coverage. Use when task is in To Review. Sets task Done or To Rework.

Launches RFC and debate discussions on GitHub. Use when proposing changes that need community input or voting.
