vvvv-shaders
by tebjanHelps write SDSL shaders for Stride and vvvv gamma — TextureFX, shader mixins, compute shaders, and ShaderFX composition. SDSL is a superset of HLSL, so use this skill when writing or debugging .sdsl shader files, GPU shaders, visual effects, HLSL code for vvvv, working with the Stride rendering pipeline, composing shader mixins, or any GPU/compute work. Trigger even if the user says 'HLSL', 'shader', 'GPU effect', 'render pass', or 'compute' in a vvvv context.
vvvv-spreads
by tebjanHelps write code using vvvv gamma's Spread<T> immutable collection type and SpreadBuilder<T>. Use when working with Spreads, SpreadBuilder, collections, arrays, iteration, mapping, filtering, zipping, accumulating, or converting between Span and Spread. Trigger whenever the user writes collection-processing C# code in vvvv — even if they say 'list', 'array', or 'IEnumerable' instead of Spread, this skill likely applies.
vvvv-troubleshooting
by tebjanDiagnoses and fixes common vvvv gamma errors in C# nodes, SDSL shaders, and runtime behavior. Use when encountering errors, exceptions, crashes, red nodes, shader compilation failures, missing nodes in the browser, performance issues, or unexpected behavior.
vvvv-testing
by tebjanSet up and run automated tests for vvvv gamma packages and C# nodes -- VL.TestFramework with NUnit for library/package authors (CI-ready), test .vl patches with assertion nodes, and lightweight agent-driven test workflows. Use when writing tests for vvvv packages, setting up test infrastructure, creating test patches, running automated compilation checks, or integrating vvvv tests into CI/CD.
vvvv-fundamentals
by tebjanExplains vvvv gamma core concepts — data types, frame-based execution model, pins, pads, links, node browser, live compilation (source project vs binary reference workflows), .vl document structure, file types (.vl/.sdsl/.cs/.csproj), ecosystem overview, and AppHost runtime detection. Use when the user asks about vvvv basics, how vvvv works, the live reload model, when to patch vs code, or needs an overview of the visual programming environment.
vvvv-channels
by tebjanHelps work with vvvv gamma's Channel system from C# — IChannelHub, public channels, [CanBePublished] attributes, hierarchical data propagation, channel subscriptions, bang channels, and spread sub-channels. Use when reading or writing public channels from C# nodes, publishing .NET types as channels, working with IChannelHub, subscribing to channel changes, managing hierarchical channel state, or implementing reactive/observable data flow. Trigger for any mention of IChannel, IChannelHub, reactive binding, observable state, two-way data binding, or TryGetChannel in a vvvv context.
vvvv-custom-nodes
by tebjanHelps write C# node classes for vvvv gamma — the [ProcessNode] lifecycle pattern, Update() method, out parameters, pin configuration, change detection, stateless operation nodes, the public-API import model, and service consumption via NodeContext (IFrameClock, Game access, logging). Use when writing a node class, adding pins, implementing change detection, accessing services in node constructors, creating stateless utility methods, or deciding whether a class needs [ProcessNode] at all. Requires the assembly to have one of [assembly: ImportAsIs] / [assembly: ImportNamespace] / [assembly: ImportType] set (see vvvv-node-libraries).
vvvv-debugging
by tebjanSet up debugging for vvvv gamma C# node projects -- generate VS Code launch.json and tasks.json configurations, attach debugger to running vvvv, configure Visual Studio debug profiles, and use debugging best practices. Use when setting up a debugger for vvvv, creating launch configurations, attaching to vvvv process, or troubleshooting breakpoints in C# nodes. Supports multiple launch configs for different test scenarios/patches.
vvvv-dotnet
by tebjanHelps with .NET integration in vvvv gamma — NuGet packages, library references, .csproj project configuration, the [assembly: ImportAsIs] attribute, vector type interop, and async patterns. Use when adding NuGet packages, configuring build settings, referencing external .NET libraries, setting up the ImportAsIs assembly attribute, working with System.Numerics/Stride type conversions, or when nodes aren't appearing in the node browser due to missing assembly configuration.
vvvv-editor-extensions
by tebjanHelps create vvvv gamma editor extensions — .HDE.vl file naming, Command node registration with keyboard shortcuts, SkiaWindow/SkiaWindowTopMost window types, docking with WindowFactory, and API access to hovered/selected nodes via VL.Lang Session nodes. Use when building editor plugins, custom tooling windows, or automating editor workflows.
vvvv-fileformat
by tebjanDescribes the .vl XML file format used by vvvv gamma — document structure, element hierarchy, ID system (base62 GUIDs), NodeReference/Choice patterns, Pins, Pads (IOBoxes), Links, ProcessDefinition/Fragment lifecycle, regions (If/ForEach/Cache), type definitions, TypeAnnotations, and property serialization. Use when generating, parsing, or modifying .vl files programmatically, or when understanding the structure of vvvv patches at the XML level.
vvvv-node-libraries
by tebjanHelps set up C# library projects that provide nodes to vvvv gamma — project directory structure, Initialization.cs with AssemblyInitializer, service registration via RegisterService, IResourceProvider factories, ImportAsIs / ImportNamespace / ImportType selection, category organization, .csproj setup, and dynamic node factories via RegisterNodeFactory. Also covers contributing changes to an existing/upstream vvvv library — fork → branch → PR workflow, editable source packages (--package-repositories / --editable-packages), and the .vl-document diff problem. Use when creating a new vvvv library, VL package, NuGet package for vvvv, deciding which import attribute to use, organizing categories, controlling which public types become nodes, registering services or node factories, setting up the project structure, or contributing a fix/feature/PR to a library you don't own (e.g. VL.StandardLibs). Trigger when the user says 'create a package', 'make a library', 'distribute nodes', 'organize categories', 'hide intern

Standardizing Agent Capabilities with SKILL.md and Model Context Protocol (MCP)
In the rapidly evolving landscape of artificial intelligence, LLM agents (Large Language Model agents) have transitioned from simple text predictors to autonomous problem solvers. To orchestrate complex, multi-step agentic workflows, developers require a standardized format to specify agent capabilities, prompt instructions, system rules, and database bindings. This is where SKILL.md and the Model Context Protocol (MCP) have emerged as standard developer paradigms. SkillMD serves as the central directory for indexing, exploring, and sharing these critical agent configurations.
Our open-source registry currently tracks over 1.7 million collected SKILL.md configurations and system prompts. By compiling agent configurations from active developers on GitHub, we bridge the gap between prompt engineering research and production execution. Whether you are building agents with Anthropic's Claude Code, OpenAI's GPT-4, Google's Gemini, or local models using Ollama and LlamaIndex, standardized skill definitions ensure your agents behave predictably across different runtime environments.
What is the Model Context Protocol (MCP)?
The Model Context Protocol (MCP) is an open-source standard designed to connect LLMs to data sources, developer tools, and external environments. MCP establishes a bidirectional communication channel between client applications (like Cursor, Claude Desktop, or custom agent systems) and servers hosting data or capabilities. Standardizing instructions via SKILL.md enables LLMs to query databases, read local files, execute terminal commands, and integrate third-party APIs. SkillMD allows you to find ready-to-run MCP servers and prompt instructions for various occupations and technical tasks.
The Structure of a Professional SKILL.md File
A valid SKILL.md configuration is designed to be easily read by humans and parsed by LLMs. It contains precise system instructions, trigger conditions, required parameters, and execution examples. Below is the typical architectural blueprint of a professional agent skill:
- Metadata & Core Scope: Declares the name of the skill, author details, target models, and a description of the capability.
- Triggers & Intent Detection: Details semantic triggers that help the agent decide when to invoke this skill.
- System Prompts: Explicit system-level instructions that direct the agent's behavior, personality, safety guardrails, and formatting preferences.
- Capabilities & Tools: Lists the files, databases, or APIs the agent must access to complete the tasks.
- Few-Shot Examples: Demonstrates real inputs and outputs, helping the model generalize behavior through in-context learning.
Optimizing Agent Workflows for Modern LLMs
Writing effective agent skills requires deep knowledge of prompt engineering. With the release of advanced reasoning models like Claude 3.5 Sonnet, ChatGPT o1, and DeepSeek-V3, prompt templates must focus on structured thinking. Developers are encouraged to use XML tags (e.g., <thought>, <context>, and <rules>) to isolate execution boundaries. Standardized prompts prevent agents from suffering from context drift, ensuring that long-running tasks remain aligned with the initial system parameters.
Exploring by SOC Occupations and Creator Profiles
What makes SkillMD unique is its taxonomy. Instead of simple text search, we parse and organize files according to the Standard Occupational Classification (SOC) system. This means you can discover skills written for Computer and Mathematical roles, Business and Financial operations, Legal, Design, and and Educational Instruction fields. By tracking creator profiles, developers can study how different teams organize their custom instructions, compare version updates, and fork public configs for specialized enterprise use cases.
SkillMD operates as a high-performance index running on a fast Go backend and a highly responsive Astro SSR frontend. All search queries execute in milliseconds, featuring smart debouncing to prevent multiple API requests while keeping user data secure.
