gpio-config
by claudius-arsAssigns, validates, and generates code for GPIO pin configurations on Raspberry Pi and ESP32 embedded projects. Activates for queries about GPIO pins, wiring, pin mapping, pin conflicts, I2C, SPI, UART, PWM, 1-Wire, CAN, ADC configuration, device tree overlays, config.txt, sdkconfig, strapping pins, boot pins, flash voltage, or connecting sensors, displays, and modules such as BME280, SSD1306, DHT22, LoRa, GPS, MCP2515, and NeoPixels. Covers Pi 3, Pi 4, Pi 5, Zero 2W, ESP32, ESP32-S2, ESP32-S3, ESP32-C3, and ESP32-C6. Produces platform-specific config files and initialization code for Python gpiozero, RPi.GPIO, Arduino, and ESP-IDF frameworks. Also activates when a device and board are named without mentioning GPIO, e.g. 'BME280 on a Pi 4' or 'connect a GPS to my ESP32', or when pin selection or pin safety questions arise.
bg-removal
by claudius-arsRemoves backgrounds from images and produces transparent PNGs with anti-aliased edge blending. Use this skill when the user wants to remove a background from an image, make an image background transparent, cut out a subject from a photo, remove a white background, extract a logo or icon from a solid background, or prepare images for compositing. Also trigger when the user mentions "transparent PNG", "remove bg", "cutout", "background removal", "isolate the subject", "make this logo transparent", or uploads an image and asks to clean up or separate the foreground. Works with white, light, or colored solid backgrounds using color-based thresholding with tunable parameters. Do NOT use for AI-based semantic segmentation, photo editing beyond background removal, format conversion without transparency, image resizing or cropping, or removing complex multi-color or gradient backgrounds.
deepwiki-context
by claudius-arsFetches AI-generated documentation from DeepWiki (deepwiki.com) for any public GitHub repository and injects it as context during coding workflows. Activates when working with third-party libraries, exploring unfamiliar codebases, debugging dependency issues, needing architectural understanding of open-source projects, or when a developer mentions understanding a library's internals, asks "how does X work under the hood", raises architecture questions about dependencies, references deepwiki.com, requests documentation for a GitHub repo, says "pull docs for", "get context on", "explain the architecture of", "how is X structured", or references a GitHub org/repo being integrated with. Also activates when additional context about a dependency would improve the current task. Do NOT activate for general coding questions, private repositories, writing original documentation, or when the user already has the information they need.

Explore the agent skills ecosystem by occupation and creator
SkillMD is not just a keyword search box. It is an open map that organizes public skills by occupation, creator, and repository, helping you see which workflows, judgment criteria, and domain habits people are writing for AI agents.
Then follow creators and GitHub repositories back to the source: compare the skills a team maintains, whether the repo is active, and how the README frames the work before you open, install, or reuse anything.
Use it three ways: learn an unfamiliar field by occupation, study how creators organize skills, then use source context to decide what is worth opening or reusing.
01 Map a field
Browse 23 occupation groups and 867 SOC roles to learn what skills exist in adjacent domains and how they break down real work.
02 Follow creators
Use creator and repository pages to inspect maintained skill collections, recent updates, and source context before trusting a result.
03 Search with sources
Search 1.7M+ collected skills, then use occupation tags, creators, and GitHub source context to decide what is worth opening.
Start with the occupation map, then follow creators and repositories back to real code. SkillMD helps explain why a skill is worth opening, not only what it is named.
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. Join our community of developers to standardize your AI agent instructions and optimize your LLM prompting workflows today.
