threat-modeling
by rjmurilloStructured security analysis using OWASP Four-Question Framework and STRIDE methodology. Generates threat matrices with risk ratings, mitigations, and prioritization. Use for attack surface analysis, security architecture review, or when asking what can go wrong.
negotiation
by rjmurilloDeal intelligence skill for offer analysis and counter-proposal drafting. Trigger on `review this offer`, `analyze counter`, `value gap`, `draft counter`, `should I walk`. Apply when reviewing any offer (real estate, compensation, vendor, resource allocation) or designing negotiation analysis behavior in agentic systems. Quantifies value gaps, applies RADAR protocol, enforces senior-tier model routing.
fix-markdown-fences
by rjmurilloRepair malformed markdown code fence closings. Use when you say "fix markdown fences", "repair code block closings", "markdown rendering broken", "code blocks bleeding into content", or "validate markdown code blocks" on any .md file. Do NOT use for documentation accuracy checks or verifying code examples (use doc-accuracy).
programming-advisor
by rjmurilloEvaluate existing solutions (libraries, SaaS, open source) AND internal prior-art before custom development to avoid reinventing the wheel. Use when considering building new features, asking "should I build or use existing", "do we already have this", "is there existing code for X in this repo", "is there a library for this", or need build vs buy cost analysis with token estimates. Checks internal reuse (leverage/extend) before external. Do NOT use for strategic multi-option TCO (use buy-vs-build-framework).
pr-autofix
by rjmurilloAutonomous PR monitor and fixer per docs/autonomous-pr-monitor.md. Triages open PRs by tier, addresses thread feedback, fixes CI failures, and enables auto-merge when the 4-condition Ready-to-Merge gate passes.
chaos-experiment
by rjmurilloDesign and document chaos engineering experiments. Guide steady state baseline, hypothesis formation, failure injection plans, and results analysis. Use when you say "design a chaos experiment", "plan a game day", "failure injection", "test resilience", or "chaos engineering". Do NOT use for security threat analysis (use threat-modeling) or pre-launch project risk identification (use pre-mortem).
research
by rjmurilloResearch external topics, create comprehensive analysis, and incorporate learnings into memory systems
analysis-provenance
by rjmurilloIdentify code ownership before modifying validators or linters. Checks file headers for provenance indicators, reviews documentation, and determines provenance as UPSTREAM, LOCAL, VENDOR, or UNKNOWN. Prevents accidental modification of upstream tools.
adr-generator
by rjmurilloCreate comprehensive Architectural Decision Records (ADRs). Researches the destination directory to detect existing template conventions, gathers context, determines next ADR number, generates the ADR, validates completeness, and saves. Supports multiple ADR formats (MADR, Nygard, Alexandrian, project canonical). Use when documenting technical decisions or creating new ADR files. Use when you say "write an ADR", "document this decision". Do NOT use to debate or review an existing ADR (use adr-review).
avoiding-manufactured-work
by rjmurilloDetect and stop manufactured work after a deliverable appears done. Use when a worker has produced a plan, issue, PR, backlog item, research artifact, or follow-up task and you need to verify it was demanded by a real user, acceptance criterion, or blocked decision instead of reward-seeking activity.
book-to-skill
by rjmurilloInput adapter that extracts a book's method into a structured payload and hands it off to SkillForge. Use when an operator wants to turn a methodology-bearing book (The Mom Test, Make It Stick, Influence, The Pragmatic Programmer, etc.) into one or more executable skills without hand-crafting the SkillForge prompt or bypassing SkillForge's triage and review gates.
codebase-documenter
by rjmurilloScaffold project documentation (README, ARCHITECTURE, API, CODE_COMMENTS) from templates with documented standards. Use when bootstrapping docs for a new or under-documented codebase.

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.
