Automated code validation for diff review, change hygiene, and red flag detection. Use when reviewing git diffs, PRs, or changed files for test disabling patterns, secrets, path portability issues, security flags, and large deletions. Supports Python, TypeScript, JavaScript, HTML, and CSS.

Generate pytest test templates for LiquidationHeatmap modules following TDD patterns. Automatically creates RED phase tests with fixtures, coverage markers, and integration test stubs.

Handle Advent of Code answer submissions with intelligent retry logic. Submits answers via aoc-cli, parses responses, handles failures, analyzes edge cases when tests pass but submission fails, and manages exponential backoff. Use when submitting AoC answers, handling submission failures, or implementing retry logic.

Use when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes
