review-metrics
by b4tchknAnalyze team code review activity and performance metrics from GitHub PRs. Use when: (1) User asks about team review statistics or performance, (2) User wants to see who reviewed what PRs, (3) User asks about review response times or approval rates, (4) User mentions "review metrics", "review stats", "review activity", or "レビュー分析", (5) User asks about review bottlenecks, stuck PRs, or review load.
claude-md-best-practice
by b4tchknAudit and automatically improve CLAUDE.md files based on Claude Code best practices. Scans for all CLAUDE.md files in the repository, evaluates them against established guidelines (line length, structure, monorepo loading behavior, shared vs component-specific content), reports findings, and applies concrete edits to fix issues.
settings-audit
by b4tchknAudit and improve Claude Code settings files (.claude/settings.json, .claude/settings.local.json, ~/.claude/settings.json) against official best practices. Detects missing attribution configuration, bloated permission allowlists, insecure deny-rule gaps, deprecated keys, and ill-scoped hooks; then proposes or applies concrete edits.
check-github-ci
by b4tchknCheck GitHub Actions CI status and provide root cause analysis with fix suggestions for any failures.
create-draft-pr
by b4tchknAutomated Draft PR creation based on Git change analysis
semantic-commit
by b4tchknSplit large changes into meaningful minimal units and commit with semantic messages
copy-simple-qa-cases
by b4tchknGenerate QA test cases from branch diff and PR body for manual testing handoff. Use when the user wants to create test cases, QA checklist, or testing instructions for a pull request.
subagent-driven-prompt-tuning
by b4tchknTune Claude Code skills, slash commands, task prompts, CLAUDE.md sections, or code-generation prompts by dispatching unbiased subagents to execute them. Evaluates both the executor's self-report and caller-side metrics (tool_uses, duration, retries), then iterates until improvements plateau. Use after authoring or significantly revising a prompt, or when you suspect the root cause of an agent misbehaving is ambiguity on the instruction side.
analyze-usage
by b4tchknAnalyze Claude Code usage and costs using ccusage CLI. Provides daily/monthly reports with cost summaries, trend analysis, and optimization insights.
skill-audit
by b4tchknAudit and improve Claude Code skill definitions (.claude/skills/*/SKILL.md, ~/.claude/skills/*/SKILL.md, and plugin-local skills) against official frontmatter semantics and progressive-disclosure best practices. Detects over-broad allowed-tools, missing description triggers, oversized SKILL.md bodies, invalid context/model values, and monorepo discovery mismatches; then proposes or applies concrete edits.
ai-review-triage
by b4tchknTriage AI/bot review comments on a PR and report whether each one is worth acting on. Reads comments from the current branch's PR (or a specified PR number), filters out human comments, then classifies each AI/bot comment as actionable, optional, or dismissable with reasoning.
pr-auto-update
by b4tchknAuto-update PR descriptions based on Git change analysis

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.
