tdd
by TechDufus
"Systematic TDD methodology for writing tests first. Use when implementing features or fixes with OMC_TDD_MODE enabled, when unsure how to structure tests, or when test-first discipline needs reinforcement. Triggers on: 'tdd', 'test first', 'test driven', 'red green refactor'."
worktree
by TechDufus
"Git worktree automation for isolated feature development. Triggers on: '/worktree create', '/worktree list', '/worktree remove'. Creates isolated working directories with automatic setup."
cli-ux-improver
by proflead
Improve CLI help, errors, and output. Use when a mid-level developer needs to make a CLI friendlier.

goudi
by hylarucoder
Pressure-tests an ambitious proposal and returns a grounded landing judgment (go / shrink / pause / reject / validate-first) with one minimum-viable first move, an explicit cut list, success/failure signals, and a stop rule. Use whenever a discussion has more vision than executable grounding, or the user asks how to land/ship a bold idea, define the smallest first step, scope down, pressure-test feasibility, price risk, or set a stop/rollback rule — even if they never name the skill. Triggers on 苟帝, 落地, 先落地, 怎么落地, 别太飘, 太理想化, 收一收, 砍范围, 可执行, 可验证, 最小可行, MVP, 止损, 回滚, 风险有多大, and on "make this real / be realistic / what do I do first / is this plan feasible" — including right after a geju or architecture session. Use geju instead when the goal is to open the frame and think bigger.
ask-questions-if-underspecified
by thienanblog
Clarify requirements before implementing. Do not use automatically, only when invoked explicitly.
clean-architecture
by Mindrally
Guidelines for implementing Clean Architecture patterns in Flutter and Go applications, with emphasis on separation of concerns, dependency rules, and testability.
refactor
by dirnbauer
Improve code structure and readability without changing external behavior. Covers common code smells (long methods, duplication, nested conditionals, magic numbers), safe refactoring process, design patterns (Strategy, Chain of Responsibility), type safety improvements, and extract method techniques.
refactor-clean
by dirnbauer
Code refactoring expert specializing in clean code principles, SOLID design patterns, and modern software engineering best practices. Analyzes and refactors code to improve quality, maintainability, and performance with incremental steps and stable behavior.
ruthless-refactorer
by galz10
Expertise in Senior Principal Engineering refactoring. Use when you need to eliminate technical debt, remove "AI Slop," simplify complex logic, and ensure DRY code.
code-simplifier
by nguyenthienthanh
"Detect and simplify overly complex code. Apply KISS principle - less is more."
refactor-expert
by nguyenthienthanh
"Guide safe, incremental refactoring that improves code quality without changing behavior."
cell-free-expression
by adaptyvbio
Guidance for cell-free protein synthesis (CFPS) optimization. Use when: (1) Planning CFPS experiments, (2) Troubleshooting low yield or aggregation, (3) Optimizing DNA template design for CFPS, (4) Expressing difficult proteins (disulfide-rich, toxic, membrane).
accelint-react-best-practices
by gohypergiant
React performance optimization and best practices. Use when writing React components, hooks, or JSX; refactoring React code; optimizing re-renders, memoization, or state management; reviewing React code for performance issues; fixing hydration mismatches; or implementing transitions, lazy initialization, or effect dependencies. Covers React 19+ features including useEffectEvent, Activity component, and ref props.
review-clean-code
by Heyvhuang
'Analyze code quality based on "Clean Code" principles. Identify naming, function size, duplication, over-engineering, and magic number issues with severity ratings and refactoring suggestions. Use when the user requests code quality checks, refactoring advice, Clean Code analysis, code smell detection, or mentions terms like code review, code quality, refactoring check.'

skill-improver
by Heyvhuang
"Improve skills and workflows by analyzing run artifacts and execution logs (events.jsonl/state.json) under runs/ (or OpenSpec changes/). Use when you want to iterate on skills based on real runs: find failure modes, bottlenecks, unclear prompts, missing I/O contracts, and propose concrete edits."

Go backend with Gin, MongoDB, JWT auth, and Clean Architecture.
refactoring
by cosmix
Restructures existing code to improve readability, maintainability, and performance without changing external behavior. USE WHEN: Restructuring code without changing behavior, extracting methods/classes, removing duplication, applying design patterns, improving code organization, reducing technical debt. DO NOT USE: For bug fixes (use /debugging), for adding tests (use /testing), for new features (implement directly). TRIGGERS: refactor, restructure, rewrite, clean up, simplify, extract, inline, rename, move, split, merge, decompose, modularize, decouple, technical debt, code smell, DRY, SOLID, improve code, modernize, reorganize.
data-sleuth
by petekp
Identify non-obvious signals, hidden patterns, and clever correlations in datasets using investigative data analysis techniques. Use when analyzing social media exports, user data, behavioral datasets, or any structured data where deeper insights are desired. Pairs with personality-profiler for enhanced signal extraction. Triggers on requests like "what patterns do you see", "find hidden signals", "correlate these datasets", "what am I missing in this data", "analyze across datasets", "find non-obvious insights", or when users want to go beyond surface-level analysis. Also use proactively when you notice interesting anomalies or correlations during any data analysis task.
