Hunts complexity in the current diff and APPLIES the simplifications directly to the working tree, then verifies the build. Five angles: reuse (duplicate logic, hand-rolled stdlib, platform features), quality (React/TypeScript hygiene, over-memoisation, exhaustive-deps, `any`, `CLAUDE.md`/`AGENTS.md` violations), efficiency (unnecessary work, missed concurrency, hot-path bloat), altitude (bandaid fixes special-cased onto shared code), and test discipline (repro test per bug fix, useless tests deleted, new tests only when they prevent a named failure). Hand it a `pr-reviewer` report and it applies those confirmed findings too. Use when the user says "tidy this up", "simplify", "clean up this diff", "polish my changes", "make this simpler", "apply the review findings", or "any reuse opportunities?". For a read-only report instead, use `pr-reviewer`; for the PR's title, description, or commits, use `pr-creator`.
The Essentialist. Ruthlessly simplifying code, removing dead features, and enforcing Clean Architecture.
CI-only Simplify & Harden workflow for pull requests using gh-aw (GitHub Agentic Workflows). Runs headless scan-and-report checks for simplify/harden/document, posts structured findings, and can block merges on critical or advisory classes. Use when: you want automated quality/security review in CI without interactive approvals.
Engineering-discipline toolkit for non-technical users working with AI coders. Wields KISS, DRY, YAGNI, fail-fast, and idempotency as commands. Use when the user asks to audit, simplify, clean up, dedupe, or harden code; or says "make this simpler", "any duplicates?", "is this safe to run twice", "explain this app", "find dead code", "simplify the plan", or "find silent failures".
This skill should be used when the user asks to refactor specific files or directories, simplify recently changed code, clean up dead code in a limited scope, or invokes `/refactor` with paths or semantic queries.
Refactor code after tests pass. The "Refactor" phase of Red-Green-Refactor.
Deep code simplification, refactoring, and quality refinement. Analyzes structural complexity, anti-patterns, and readability debt, then applies targeted refactoring preserving exact behavior. Language-agnostic: Python, Go, TypeScript/JavaScript, Rust. Use this skill when the goal is simplification and clarity rather than bug-finding. Triggers on: "simplify this code", "clean up my code", "refactor for clarity", "reduce complexity", "make this more readable", "code quality pass", "tech debt cleanup", "run the code refiner", "simplify recent changes", "this code is messy", "too much nesting", "this function is too long", "clean this up before I PR it", "tidy up my code", cyclomatic complexity, cognitive complexity, code smells.
Perform a refactor pass focused on simplicity after recent changes. Use when the user asks for a refactor/cleanup pass, simplification, or dead-code removal and expects build/tests to verify behavior.
Post-completion self-review for coding agents that runs simplify, harden, and micro-documentation passes on non-trivial code changes. Use when: a coding task is complete in a general agent session and you want a bounded quality and security sweep before signaling done. For CI pipeline execution, use simplify-and-harden-ci.
Audit code architecture for over-engineering and unnecessary abstractions. Use when user asks to "review architecture", "simplify code structure", "reduce over-engineering", "evaluate abstractions", or mentions premature abstraction, interface proliferation, factory patterns, YAGNI, or enterprise-grade complexity.
Refactor code to simplify it without changing behavior.
Simplifies, polishes, and declutters code without changing behavior. Use when asked to simplify, clean up, refactor, declutter, remove dead code or AI slop, or improve readability. For analysis-only reports without code changes, use code-simplicity-reviewer agent.
