io.github.vellum-ai/vellum-assistant/typescript-eval

Test TypeScript code snippets before persisting as skills

io.github.gogs/gogs/react-doctor

Use when finishing a feature, fixing a bug, before committing React code, or when the user types `/doctor`, asks to scan, triage, or clean up React diagnostics. Covers lint, accessibility, bundle size, architecture. Includes a regression check and a full local-triage workflow that fetches the canonical playbook.

io.github.alas-poor-ophelia/windrose-md/css-modern-features

Use this skill whenever writing, reviewing, or refactoring any CSS, whether in plain .css files, styled-components, CSS Modules, Tailwind arbitrary values, inline styles in React/Vue/Svelte, or any other frontend context. This skill ensures modern CSS features are used wherever browser support allows — things like clamp(), :has(), container queries, OKLCH colors, scroll-driven animations, anchor positioning, @starting-style, light-dark(), text-wrap: balance, and more. Trigger this skill any time CSS is being written or touched, even indirectly (e.g. a component that needs responsive sizing, a theme system, an animation, a layout). Do NOT default to legacy patterns like px-based media queries, JS-driven animations, or CSS-in-JS workarounds when a native modern CSS feature exists and is supported by the project's browser targets.

io.github.PurpleAILAB/Decepticon/sqli

SQL Injection — automated and manual exploitation of unsanitized SQL queries. Covers Union-based, Error-based, Blind (Boolean/Time-based), and Stacked queries. Includes sqlmap automation with WAF bypass tamper scripts.

Hunt SQL injection (CWE-89) via source-level taint tracking. Covers string concat, format-string, ORM raw queries, second-order injection, and NoSQL injection in MongoDB/DynamoDB.

io.github.prisma/prisma/ast-visitor-pattern

Use the frozen-class/visitor pattern for discriminated unions that have multiple dispatch sites. Use when creating a new set of variants (commands, IR nodes, factory calls) that will be switched over in 2+ places, or when refactoring an existing union type that has grown multiple switch sites.

io.github.project-chip/connectedhomeip/python-test-runner

Guidelines and instructions for building prerequisite example applications and running python-based integration and certification tests located in `src/python_testing/`. Use this skill to run important regression tests during developement or, when building new example apps, or when there is a need to execute python test scripts or "certification test scripts" or mentions of run_python_test.py and local.py.

io.github.agentscope-ai/AgentTeams/mcporter

Discover and call MCP Server tools via the mcporter CLI. Use when your coordinator notifies you about new MCP tools, or when you need to call external APIs. Includes workflow for generating skill documentation for new MCP servers.

io.github.agentscope-ai/HiClaw/mcporter

Discover and call MCP Server tools via the mcporter CLI. Use when your coordinator notifies you about new MCP tools, or when you need to call external APIs. Includes workflow for generating skill documentation for new MCP servers.

io.github.elastic/kibana/kbn-github

GitHub interactions via gh CLI for the Kibana repo. Use when performing any GitHub interaction — creating, viewing, or modifying PRs or issues, posting comments or reviews, checking CI status, applying labels, creating releases, or making any gh/API call.

io.github.shader-slang/slang/design-docs-incremental-update

Incrementally refresh the LLM-generated design docs under docs/generated/design/. Use when the user asks to update, refresh, or regenerate the generated design documentation after source changes. Runs the three-stage operator loop defined in docs/generated/design/_meta/regenerate.md - (1) regenerate stale docs (Claude), (2) direct the user to run the non-Claude review, (3) apply remediation (Claude) - with explicit confirmation before stages 1 and 3.

io.github.sickn33/antigravity-awesome-skills/nextjs-seo-indexing

io.github.vudovn/ag-kit/mcp-builder

MCP (Model Context Protocol) server building principles. Tool design, resource patterns, best practices.

io.github.vudovn/ag-kit/testing-patterns

Testing patterns and principles. Unit, integration, mocking strategies.

io.github.swapnildahiphale/OpenSRE/infrastructure-kubernetes

Kubernetes debugging methodology and scripts. Use for pod crashes, CrashLoopBackOff, OOMKilled, deployment issues, resource problems, or container failures.

io.github.abhigyanpatwari/GitNexus/gitnexus-cli

Use when the user needs to run GitNexus CLI commands like analyze/index a repo, check status, clean the index, generate a wiki, or list indexed repos. Examples: "Index this repo", "Reanalyze the codebase", "Generate a wiki"

io.github.nexu-io/open-design/redesign-skill

Upgrades existing websites and apps to premium quality. Audits current design, identifies generic AI patterns, and applies high-end design standards without breaking functionality. Works with any CSS framework or vanilla CSS.

io.github.nexu-io/open-design/imagegen-frontend-web

Elite frontend image-direction skill for generating premium, conversion-aware website design references. CRITICAL OUTPUT RULE — generate ONE separate horizontal image FOR EVERY section. A landing page with 8 sections produces 8 images. Never compress multiple sections into one image. Enforces composition variety (not always left-text / right-image), background-image freedom, varied CTAs, varied hero scales (giant / mid / mini minimalist), narrative concept spine, second-read moments, and a single consistent palette across all images. Optimized for landing pages, marketing sites, and product comps that developers or coding models can accurately recreate.

io.github.nexu-io/open-design/imagegen-frontend-mobile

Elite mobile app image-generation skill for creating premium, app-native screen concepts and flows. Designed for iOS, Android, and cross-platform mobile products. Prioritizes clean hierarchy, comfortably readable text, strong multi-screen consistency, controlled color palettes, non-generic creative direction, textured surfaces, image-led composition, tasteful custom iconography, and clean phone mockup framing. By default, screens should be shown inside a subtle premium iPhone or similar phone mockup with a visible frame, while the main focus stays on the app content itself. This skill generates images only. It does not write code.

io.github.nexu-io/open-design/brandkit

Premium brand-kit image generation skill for creating high-end brand-guidelines boards, logo systems, identity decks, and visual-world presentations. Trained for minimalist, cinematic, editorial, dark-tech, luxury, cultural, security, gaming, developer-tool, and consumer-app brand systems. Optimized for intentional logo concepting, refined composition, sparse typography, strong symbolic meaning, premium mockups, art-directed imagery, and flexible grid layouts.

io.github.nexu-io/open-design/gpt-tasteskill

Elite UX/UI & Advanced GSAP Motion Engineer. Enforces Python-driven true randomization for layout variance, strict AIDA page structure, wide editorial typography (bans 6-line wraps), gapless bento grids, strict GSAP ScrollTriggers (pinning, stacking, scrubbing), inline micro-images, and massive section spacing.
