# SKILL.md ## Name VimReaper ## Description VimReaper is a dead‑code cleanup skill that systematically scans a codebase to identify and safely remove unused code—dead functions, unreachable blocks, obsolete variables, redundant imports, and leftover comments—while preserving the intended logic and test suite. As its name suggests, VimReaper wields the **vim editor** as its primary scalpel: code removal is performed using vim’s precise ex commands, search patterns, and scripted editing modes, m
development
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
development
Find deepening opportunities in a codebase, informed by the domain language in CONTEXT.md and the decisions in docs/adr/. Use when the user wants to improve architecture, find refactoring opportunities, consolidate tightly-coupled modules, or make a codebase more testable and AI-navigable.
testing
Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".
