code-modernization

Guides modernization of legacy codebases while preserving behavior. Use when the user asks to modernize legacy code, migrate COBOL, legacy Java, C++, .NET, procedural PHP, classic ASP, or monolith systems; extract business rules; replatform, refactor, rewrite, or rebuild a legacy module; apply a strangler fig migration; or harden legacy code before migration.

Code & Development Listed

code-review

Reviews pull requests, git diffs, branches, and code changes for bugs, regressions, repository guideline violations, and high-confidence risks. Use when the user asks for a code review, PR review, pull request review, review of changes, review this diff, or wants automated review feedback before merge. For GitHub pull requests, requires the GitHub CLI (`gh`) authenticated in the target repository.

Web & Frontend Listed

extract-theme

Extracts the visual theme (colors, typography, radius, spacing, shadows) of a public website provided by the user and produces a shadcn/ui + Tailwind CSS v4 compatible token block, ready to paste into the project's `globals.css` (or `app.css`) inside `@theme` and `.dark`. Uses the chrome-devtools MCP server to drive a real Chromium instance (no Playwright). Use when the user asks to "extract the theme of <url>", "reverse-engineer the design tokens of <site>", "copy the look of <site> into shadcn", "build a tailwind v4 theme from <url>", or mentions extract-theme / theme extraction / design tokens from a URL.

find-skills

Helps users discover and recommend agent skills that are ALREADY installed locally on the host (Claude Code, Cursor, Codex, generic agents), without any network call or external CLI. Use when the user asks "how do I do X", "is there a skill for X", "find a skill", "what skills do I have", "list my skills", "which skills are installed", "do I have a skill that can…", or expresses interest in extending capabilities with what's already on disk. Strictly local: never runs `npx skills find`, `npx skills add`, `npx skills update`, or fetches from skills.sh.

goal

Keep an AI coding agent working toward one explicit completion condition across turns. Use when the user invokes `/goal`, asks to keep working until a condition is met, wants an autonomous loop with verifiable completion, or needs guidance writing effective goal conditions.

imagegen

Generates or edits images for the current project (website assets, game assets, UI mockups, product mockups, wireframes, logos, photorealistic scenes, infographics) using gpt-image-2 via the local Codex CLI authenticated with the user's ChatGPT subscription. Use when the user asks to generate, edit, restyle, mockup, or remix images, or mentions gpt-image-2 / GPT Image 2 / ChatGPT Images 2.0.

shaders

Guides building GPU-accelerated visual effects in React / Next.js with the `shaders` npm package from shaders.com — declarative `<Shader>` component trees, composition (stacking, nesting, blend modes, masking), reactive props, dynamic prop drivers (`auto-animate`, `mouse-position`, `map`), shape (SDF) effects, color space, performance budget (RTT / generator vs filter), and SSR safety. Use when the user asks to add a "shader background", "WebGPU effect", "aurora / plasma / swirl / glass / cursor-trail" hero, mentions shaders.com, the `shaders/react` package, the `<Shader>` component, or wants animated GPU-rendered visuals in a React or Next.js app. Not for raw GLSL / WebGL / Three.js / react-three-fiber work — those use different APIs.

vite-plus-best-practices

Provides best practices for Vite+ (vp), the unified web toolchain combining Vite, Vitest, Oxlint, Oxfmt, Rolldown, tsdown, and Vite Task. Covers the vp command surface (dev, build, check, test, run, pack, install, env), unified vite.config.ts blocks, monorepo overrides, task caching, commit hooks, library packaging, and migrating existing Vite/Vitest/ESLint/Prettier projects. Use when the user mentions Vite+, vite-plus, the `vp` or `vpx` CLI, Oxlint/Oxfmt in a Vite context, tsdown, Vite Task, or asks to configure, migrate, scaffold, or upgrade a Vite+ project.
