Scans codebases for technical debt with AST parsing, prioritizes debt items by impact, and generates trend dashboards. Use when tracking tech debt, prioritizing refactoring, or measuring code quality trends over time.
Run findings-first review for Atlan app changes and synchronize app documentation with implemented behavior. Use when completing a change set, preparing handoff, or auditing regressions.
Detect codebase bloat through progressive analysis: dead code, duplication, complexity, documentation bloat. Use when context usage high, quarterly maintenance, pre-release cleanup, before refactoring. Do not use when active feature development, time-sensitive bugs, codebase < 1000 lines.
17 principles of Unix software design, from Eric Raymond's *The Art of Unix Programming*. You can refer to these principles when carrying out software design.
Improve code readability without altering functionality using idiomatic best practices
Review code for conceptual errors, wrong assumptions, edge cases, and overcomplication; use after medium/large changes or when risk is high.
Use this skill when validating ANY potential code review finding. Apply BEFORE classifying to verify the finding is real; can you trace incorrect behavior, is it handled elsewhere, and are you certain about framework semantics? If any answer is no, DO NOT create the finding.
Reduces JS/TS bundle size via unused deps, tree-shaking, code splitting with keep/discard
Review git diffs, staged changes, and GitHub PRs. Change-focused analysis across seven pillars (Security, Performance, Architecture, Error Handling, Testing, Maintainability, Paranoia) with numeric scoring 1-10. Supports GitHub PR review, staged changes, and arbitrary diffs. Use when: reviewing a PR, reviewing staged changes, reviewing a diff, pre-commit review. Triggers: review PR, review my changes, review the diff, review staged, review-pr, check my changes.
Systematic codebase quality scan for identifying duplication, redundancy, and improvement opportunities. Use when reviewing a repo's architecture, finding refactoring targets, or assessing code health. Triggers: "scan the repo", "find code duplication", "suggest improvements", "code quality review", "is there redundant code", "refactoring plan", "architecture review".
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.
Review code changes in Tenzir projects. Use when auditing diffs or pull requests for bugs, security issues, missing tests, documentation drift, readability problems, performance regressions, user experience issues, or when deciding how to respond to GitHub review comments. Also use this skill whenever the user says "review", "look at this PR", "check my changes", "audit this diff", "what do you think of this code", or asks for feedback on any code they've written or changed — even if they don't explicitly say "code review."
