gdb-chat
by ryanbreenConversational GDB debugging for Breenix kernel. Use for interactive debugging sessions - set breakpoints, inspect registers, examine memory, step through code, investigate crashes.
github-workflow-authoring
by ryanbreenThis skill should be used when creating or improving GitHub Actions CI/CD workflows for Breenix kernel development. Use for authoring new test workflows, optimizing existing CI pipelines, adding new test types, fixing workflow configuration issues, or adapting workflows for new kernel features.
integration-test-authoring
by ryanbreenThis skill should be used when creating new integration tests for Breenix kernel features. Use for writing shared QEMU tests with checkpoint signals, creating xtask test commands, adding test workflows, and following Breenix testing patterns.
interrupt-trace
by ryanbreenUse when analyzing low-level interrupt behavior - debugging interrupt handler issues, investigating crashes or triple faults, verifying privilege level transitions, analyzing register corruption between interrupts, or understanding interrupt sequencing and timing issues.
legacy-migration
by ryanbreenThis skill should be used when migrating features from src.legacy/ to the new kernel implementation or removing legacy code after reaching feature parity. Use for systematic legacy code removal, updating FEATURE_COMPARISON.md, verifying feature equivalence, and ensuring safe code retirement.
log-analysis
by ryanbreenThis skill should be used when analyzing Breenix kernel logs for debugging, testing verification, or understanding kernel behavior. Use for searching timestamped logs, finding checkpoint signals, tracing execution flow, identifying errors or panics, and extracting diagnostic information.
memory-debugging
by ryanbreenThis skill should be used when debugging memory-related issues in the Breenix kernel including page faults, double faults, frame allocation problems, page table issues, heap allocation failures, stack overflows, and virtual memory mapping errors.
qemu-debug-session
by ryanbreenUse when setting up comprehensive QEMU debugging for Breenix - investigating interrupt handling bugs, debugging memory management issues, analyzing boot sequence problems, tracing hardware interactions, or inspecting CPU state during failures.
register-watch
by ryanbreenUse when debugging register corruption issues - registers have unexpected values after context switches, userspace processes crash with corrupted state, stack pointer corruption, syscall return values corrupted, or timer interrupt handlers corrupting register state.

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.
