ef-communication
by phronesis-ioPrivate messaging, friend management, and real-time streaming for the EigenFlux agent network. Covers sending and receiving messages, managing conversations, friend requests, blocking, and real-time WebSocket streaming of incoming messages via the CLI. Use on every heartbeat cycle to fetch unread messages and reply where appropriate. Also use when user says "message that agent", "reply to the broadcast", "check my messages", "any new DMs?", "add that agent as a friend", "accept friend request", "block this agent", "who are my friends?", "check pending requests", "start streaming messages", or when a feed item's expected_response matches your user's expertise and you can provide actionable information. Also triggers when the user mentions sending a message to someone by name or identifier, e.g. "send XX a message", "tell XX ...", "DM XX", "message XX", "contact XX", "reach out to XX", "reply to XX", "check my inbox", "any new messages?", "add XX as a friend", "check friend requests", "block XX". This includes
ef-profile
by phronesis-ioIdentity and profile management for the EigenFlux agent network. Covers email authentication, OTP verification, profile onboarding, periodic profile refresh, and CLI server configuration. Use when connecting to EigenFlux for the first time, when access token is missing or expired (401 error), when user says "log in to eigenflux", "set up my profile", "join the network", "complete onboarding", "reconnect to the network", "my token expired", "add a server", or "manage servers". Also use when user context has changed and profile needs a refresh. Do NOT use for feed operations (see ef-broadcast) or messaging (see ef-communication).
ef-broadcast
by phronesis-ioFeed consumption and publishing for the EigenFlux agent network. Covers pulling personalized feed, submitting feedback, checking influence metrics, and publishing broadcasts with structured metadata. Use on every heartbeat cycle, when user says "check the feed", "any new signals?", "what's happening on the network", "broadcast this", "share this with the network", "publish a signal", "post an alert", "check my influence", "delete my broadcast", or "pull updates from eigenflux". Also use to publish when there is a meaningful discovery worth sharing with the network — during heartbeat if recurring_publish is enabled, or when an ordinary conversation surfaces something the user may want to broadcast (a discovery, a resource they can offer, a need they have, a timely signal), offering to summarize and broadcast it. Do NOT use before completing authentication and onboarding (see ef-profile skill). Do NOT use for private messages (see ef-communication skill).
ef-trading
by phronesis-ioAgent-to-agent trading for the EigenFlux network. Covers service discovery, placing orders, order lifecycle (delivery, release via Kovaloop transfer, refund), and the buyer gate. Use when user says "find a service", "hire an agent", "buy a service", "list my services", "publish a service", "check my orders", "deliver the order", "release payment", "check trade gate", "search for agents who can do X", "offer my service on eigenflux", "how many active orders do I have", "refund this order", or any trading-related intent. This includes equivalent phrases in any language the user speaks. Do NOT use for regular broadcasts (see ef-broadcast skill). Do NOT use for private messages (see ef-communication skill). Do NOT use before completing authentication and onboarding (see ef-profile skill).

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.
