io.github.Leonxlnx/taste-skill/taste-skill

Anti-slop frontend skill for landing pages, portfolios, and redesigns. The agent reads the brief, infers the right design direction, and ships interfaces that do not look templated. Real design systems when applicable, audit-first on redesigns, strict pre-flight check.

io.github.kortix-ai/suna/pdf

Use for creating, editing, extracting, OCRing, filling, and converting PDF documents.

io.github.agentscope-ai/agentscope-java/sql-analysis

Answer a quantitative business question by writing a SQL query against the data warehouse, validating it, and presenting the result. Use when the user asks "how many...", "what's the trend of...", "compare X vs Y over...", "what's our top N...", or anything that resolves to a query against tabular data. Produces a small result table plus the underlying query.

io.github.microsoft/fluentui/review-pr

Review a PR for correctness, pattern compliance, testing, accessibility, and safety. Produces a confidence score for merge readiness.

io.github.ZHangZHengEric/Sage/mcp-builder

Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).

io.github.ZHangZHengEric/Sage/pdf

Use this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable. If the user mentions a .pdf file or asks to produce one, use this skill.

io.github.PurpleAILAB/Decepticon/docker-socket-mount

Docker / containerd socket mounted into a container → host RCE. Common in CI runners, GitOps controllers (ArgoCD, Flux), and 'Docker-in-Docker' setups. Single-command escape via `docker run --rm --privileged -v /:/host alpine chroot /host`.

io.github.PurpleAILAB/Decepticon/api

Modern API category — gRPC, SOAP/WSDL, WebSocket, Server-Sent Events. Routing skill: identify the API protocol from the response Content-Type or wire format, then load the matching sub-skill.

io.github.PurpleAILAB/Decepticon/server-sent-events

Server-Sent Events (SSE / EventSource) exploitation — origin abuse for cross-site streaming exfil, prompt-injection via SSE messages into LLM clients, retry-after token leak, fragmenting events to bypass content-type sniffers.

io.github.PurpleAILAB/Decepticon/websocket

WebSocket exploitation — origin-bypass (CSWSH cross-site WebSocket hijacking), missing per-message auth, message-type confusion, msg-flood DoS, ws→wss downgrade, hidden RPC routes in the WS frame layer.

io.github.PurpleAILAB/Decepticon/grpc

gRPC API exploitation — reflection-based discovery via grpcurl, protobuf fuzzing, missing authz on streaming RPCs, gRPC-Web → backend SSRF, mTLS bypass, metadata header injection, h2c smuggling against gRPC fronts.

io.github.PurpleAILAB/Decepticon/soap-wsdl

SOAP / WSDL exploitation — WSDL enumeration via ?wsdl, XXE in SOAP envelope, WS-Addressing replay, WS-Security UsernameToken brute, SAML token injection in WS-Trust, schema validation bypass.

io.github.luongnv89/claude-howto/code-review-specialist

Comprehensive code review with security, performance, and quality analysis. Use when users ask to review code, analyze code quality, evaluate pull requests, or mention code review, security analysis, or performance optimization.

io.github.platonai/Browser4/mcp-builder

Guide for creating advanced-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).

io.github.platonai/Browser4/pdf

Extracts text and tables from PDF files, fills PDF forms, and creates/merges/splits PDF documents. Use when users mention PDFs, forms, document extraction, or PDF generation.

io.github.vercel-labs/agent-skills/writing-guidelines

Review docs/prose for Writing Guidelines compliance. Use when asked to "review my docs", "check writing style", "audit prose", "review docs voice and tone", or "check this page against the writing handbook".

io.github.NousResearch/hermes-agent/code-wiki

Generate wiki docs + Mermaid diagrams for any codebase.

io.github.udecode/plate/typescript-advanced-types

Master TypeScript's advanced type system including generics, conditional types, mapped types, template literals, and utility types for building type-safe applications. Use when implementing complex type logic, creating reusable type utilities, or ensuring compile-time type safety in TypeScript projects.

io.github.udecode/plate/review-sweep

Mine review comments for broader diff-wide fixes instead of handling each line in isolation

io.github.QuilibriumNetwork/quorum-desktop/css-convert

Use when the user asks to convert a CSS or SCSS file to use the project's `_variables.scss` tokens, replace `@apply` with raw CSS, or align a stylesheet with the styling guidelines. Triggers on "convert this CSS", "use variables in this stylesheet", "remove @apply", "align with styling guidelines".
