kg
by gonos2kRouter for the Knowledge Graph + LLM Wiki system. Use when the user invokes /kg explicitly or asks 'which kg command should I use?'. Sub-commands — /kg-orient, /kg-update, /kg-query, /kg-lint, /kg-ingest (data ops) and /kg-reflect, /kg-challenge, /kg-connect, /kg-suggest (dialogue ops). Project-state auto-trigger (wiki/ or graphify-out/ presence) belongs to /kg-orient, not this router.
kg-schema
by gonos2kEvolve the kg ontology (온톨로지 진화/스키마 변경/분류 체계 수정). Sub-commands propose/approve/migrate/diff/list/pull-global. Changes are proposal-first; nothing is auto-applied. Per-wiki pin is default target; use --global to modify the shipped default.
kg-query
by gonos2kQuery accumulated knowledge — BFS/DFS graph traversal + wiki lookup. Supports --depth quick|standard|deep for token-efficient queries. Use when asking questions ABOUT existing knowledge (relationships, evidence, decisions). For PROPOSING new connections between communities, use /kg-connect instead.
kg-postmortem
by gonos2kThis skill should be used after a recent discrete failure, build error, unexpected result, debugging session, 삽질, or '이걸 기록해뒀어야 했는데' moment, or when the user invokes /kg-postmortem. Captures one trial-and-error event as Experience and optionally Heuristic only if user confirms generalization.
kg-merge
by gonos2kThis skill should be used when the user asks to merge graphs across multiple projects, build a cross-repo knowledge graph, says '여러 프로젝트 통합 그래프', 'cross-project KG', 'merge graphs', or invokes /kg-merge. Reads each project's graphify-out/graph.json and produces a unified graphify-out/merged-graph.json via graphify v0.8.x merge-graphs. Read-only on source projects.
kg-mcp
by gonos2kThis skill should be used when the user asks to expose the project graph as MCP tools, register the graphify MCP server (python -m graphify.serve) in Claude config, says 'graphify mcp 서버', 'MCP로 그래프 쿼리', or invokes /kg-mcp [register|status|unregister]. Configures Claude's .mcp.json so subsequent /kg-query and /kg-orient can call graphify MCP tools instead of loading graph.json directly. Edits user config — requires explicit approval.
kg-ingest
by gonos2kIngest source files into the wiki — read, discuss key takeaways, write source/entity/concept pages with wikilinks. Requires wiki/ to be initialized (run /kg-init first).
kg-connect
by gonos2kThis skill should be used when the user asks to find missing links between graph communities, bridge isolated concepts, connect two topics, or invokes /kg-connect. Proposes inferred semantic bridges with rationale and risk — never adds edges without user confirmation.
kg-challenge
by gonos2kThis skill should be used when the user asks to stress-test, challenge, falsify, or argue against a wiki claim, decision, heuristic, or assumption, says '반박해줘', '이 주장 검증해줘', 'devil's advocate', or invokes /kg-challenge. Uses only evidence already in the knowledge base — never fabricates doubt.
kg-canvas
by gonos2kThis skill should be used when the user asks to visualize the kg wiki, create an Obsidian Canvas, knowledge map, graph view, mindmap, community map, or invokes /kg-canvas. Exports read-only .canvas JSON views — never modifies content pages.
kg-suggest
by gonos2kThis skill should be used when the user asks what to read, ingest, research, or improve next in the kg wiki, says '다음에 뭘 봐야 해?', '지식 공백 찾아줘', or invokes /kg-suggest. Recommends 3-5 concrete next sources or maintenance actions based on unresolved links, stale topics, low-cohesion communities.
kg-autoresearch
by gonos2kAutonomous multi-round web research loop (자율 웹 조사/자료조사/문헌 검토). Decomposes a topic into angles, searches, fetches, extracts findings, and queues results for user approval before filing into the wiki. Governed by research-policy.yaml. Use when /kg-query --depth deep says "insufficient wiki coverage" or 새로운 주제를 체계적으로 조사할 때.

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.
