Agent Skills

io.github.ethereum/ethereum-org-website/design-system

Use when building, refactoring, or styling any UI in the ethereum.org Next.js site (`src/components/`, `app/`, `src/styles/`, `public/content/`, or any `.tsx`/`.mdx`/`.css` change that affects the rendered UI). Provides canonical component choices, design tokens, RTL/i18n rules, server/client guidance, and the "use a variant, not a new component" pattern for the project's Tailwind v4 + Radix + shadcn-style design system.

io.github.mastra-ai/mastra/react-best-practices

React performance optimization guidelines from Mastra Engineering. This skill should be used when writing, reviewing, or refactoring React code to ensure optimal performance patterns. Triggers on tasks involving React components, data fetching, bundle optimization, or performance improvements.

io.github.forcedotcom/salesforcedx-vscode/typescript

TypeScript coding standards — apply when writing, reviewing, or refactoring .ts/.tsx, or naming/renaming .ts files (camelCase casing).

io.github.abhigyanpatwari/GitNexus/gitnexus-refactoring

Use when the user wants to rename, extract, split, move, or restructure code safely. Examples: "Rename this function", "Extract this into a module", "Refactor this class", "Move this to a separate file"

io.github.codestable/CodeStable/cs-refactor

Refactor 主入口。触发：优化/重构/拆分/性能/代码太长，且不改变行为、不新增需求。不要用于新增功能(cs-feat)、修复 bug(cs-issue)、对外文档(cs-docs)、大需求拆解(cs-epic)。

io.github.cartography-cncf/cartography/refactor-legacy

Convert a legacy handwritten-Cypher Cartography sync (`load_*` / `cleanup_*` JSON jobs) into the modern declarative data model (`load()`, `GraphJob.from_node_schema()`). Use when the user asks to refactor, modernise, migrate, or "clean up" a legacy intel module, or to remove a `cleanup/*.json` job tied to an old `MERGE` query.

io.github.HoangNguyen0403/agent-skills-standard/typescript-best-practices

Write idiomatic TypeScript patterns for clean, maintainable code. Use when writing or refactoring TypeScript classes, functions, modules, or async logic.

io.github.HoangNguyen0403/agent-skills-standard/typescript-best-practices

Write idiomatic TypeScript patterns for clean, maintainable code. Use when writing or refactoring TypeScript classes, functions, modules, or async logic.

io.github.citypaul/.dotfiles/refactoring

Refactoring assessment and behavior-preserving patterns for code with a passing baseline and sufficient preservation evidence. Use when the user asks to clean up, simplify, or restructure a selected area, and after mutation testing or reviewed proportionate alternate evidence establishes confidence for the REFACTOR step. Covers commit-before-refactoring discipline, when refactoring adds value vs when to skip it, and priority classification. For any slice in a selected whole-path reduction program—transition or terminal—use reduce-system-complexity as the governing skill; refactoring may be secondary when applicable. For repository-wide architecture discovery use improve-codebase-architecture; for a module contract use codebase-design. Do NOT use for insufficiently evidenced code or adding behavior.

io.github.langfuse/langfuse/refactor-react-effects

Refactor avoidable React useEffect usage in Langfuse frontend code. Use when adding, reviewing, or removing effects; initializing forms or local UI state from query data; synchronizing client and server state; moving mutations or async workflows out of components; cleaning every effect from a frontend submodule; or reviewing whether an effect has a valid external-system owner.

io.github.langfuse/langfuse/frontend-large-feature-architecture

Use when building, changing, or refactoring large Langfuse frontend features, virtualized lists, large tables, controller components, local feature state, Zustand stores, row selection, high-frequency UI state, or rendering-performance issues. Also read BEFORE writing any useEffect (especially one that syncs fetched data into state), wiring form initialValues/defaultValues from loaded data, or adding useCallback/useMemo.

io.github.handsontable/handsontable/code-graph

Query the pre-built code-review-graph knowledge graph (Tree-sitter, whole monorepo) instead of walking call chains with Grep+Read — 2-6x cheaper, and it catches dynamic dispatch that grep misses. Use for ANY task that spans multiple files, even when the user never mentions a graph or asks for it - fixing or tracing a bug ("fix this bug", "why does X happen", "trace this"), exploring unfamiliar code ("how does X work", "who calls X", "what imports Y", "where is X used or handled"), planning or doing a refactor ("rename X", "is it safe to change or remove X", "what would break", "blast radius", "find dead code"), or reviewing changes ("review this PR", "review this branch or diff"). If you are about to Grep for a symbol to find its callers, callees, or importers, stop and use this skill instead.

io.github.hashgraph-online/awesome-codex-plugins/refactor

Execute safe refactors.

io.github.microsoft/apm/python-architecture

Activate when creating new modules, refactoring class hierarchies, introducing design patterns, or making changes spanning 3+ files in the APM CLI codebase.

io.github.microsoft/apm/python-architecture

Activate when creating new modules, refactoring class hierarchies, introducing design patterns, or making changes spanning 3+ files in the APM CLI codebase.

io.github.code-yeongyu/lazycodex/refactor

Intelligent refactor command. Triggers: refactor, refactoring, cleanup, restructure, extract, simplify, modernize.

io.github.liuzhengdongfortest/CodeStable/cs-refactor

Refactor 主入口。触发：优化/重构/拆分/性能/代码太长，且不改变行为、不新增需求。不要用于新增功能(cs-feat)、修复 bug(cs-issue)、对外文档(cs-docs)、大需求拆解(cs-epic)。

io.github.compozy/compozy/writing-skills

Author, refactor, and debug agent skills. Use when creating a new skill from scratch, pruning or restructuring a bloated SKILL.md, tightening a skill description's triggers, or diagnosing bundled references the agent ignores. Don't use for agent instruction files like CLAUDE.md or AGENTS.md (use agent-md-refactor), general documentation, or READMEs.

io.github.compozy/compozy/refactoring-analysis

Audits a codebase for refactoring opportunities using Martin Fowler's code smell and technique catalog — long functions, duplication, high coupling, complex conditionals, primitive obsession — and writes a prioritized report to docs/_refacs/. Use when auditing code quality, planning a refactoring sprint, or reviewing architectural health; not for style/formatting, performance, or security audits.

io.github.hashicorp/agent-skills/refactor-module

Transform monolithic Terraform configurations into reusable, maintainable modules following HashiCorp's module design principles and community best practices.

io.github.dzhng/skills/refactor-clean

Refactor cleanly instead of layering sediment. Use when a change reveals duplicated concepts, local adapters, obsolete owners, compatibility wrappers, parallel abstractions, an over-large module that has accreted many responsibilities, or "just tack this on" pressure in any code area.

io.github.EpicenterHQ/epicenter/refactoring

Per-change refactoring mechanics: count callers exactly, decide inline vs keep, collapse duplicate switch branches, route raw access through a single typed boundary, surgical one-change-per-commit, post-refactor straggler sweep for stale JSDoc and dead exports. Use when actually editing code to clean it up, when deciding whether a 1-caller helper earns its keep, or when planning a sequence of small refactor commits. For the smell catalog use code-audit; for session-long simplification use collapse-pass.
