agent-browser
by exceptionlessBrowser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction.
backend-architecture
by exceptionlessUse this skill when working on the ASP.NET Core backend — adding controllers, services, repositories, validators, authorization, WebSocket endpoints, jobs, Foundatio infrastructure, configuration, or Aspire orchestration. Prefer this as the backend entrypoint for project layering, C# conventions, logging, ProblemDetails, security-sensitive config, and OpenAPI baseline updates.
backend-testing
by exceptionlessUse this skill when writing or modifying C# tests — unit tests, integration tests, or test fixtures. Covers xUnit patterns, AppWebHostFactory for integration testing, FluentClient for API assertions, ProxyTimeProvider for time manipulation, and test data builders. Apply when adding new test cases, debugging test failures, or setting up test infrastructure.
frontend-architecture
by exceptionlessUse this skill as the frontend entrypoint for the Svelte 5 app in ClientApp — adding routes, creating feature slices, writing Svelte components, applying TypeScript conventions, using shared UI/formatter components, handling accessibility, or adding frontend tests. The legacy Angular app still powers most of the current site in ClientApp.angular, but all new frontend development should be Svelte UI only unless the user explicitly asks for Angular or legacy UI changes.
tanstack-query
by exceptionlessUse this skill when fetching data, managing server state, or handling API mutations in the Svelte frontend. Covers createQuery, createMutation, query keys, cache invalidation, optimistic updates, and WebSocket-driven refetching. Apply when adding API calls, managing loading/error states, or coordinating cache updates after mutations.
dogfood
by exceptionlessSystematically dogfood Exceptionless locally. Use when asked to dogfood, QA, exploratory test, bug hunt, browser-test, or validate frontend/full-stack behavior in this repo. Start from the AppHost/Aspire local URLs and choose the Svelte or legacy Angular app based on the changed surface. External Exceptionless URLs require an explicit user-provided URL and confirmation.
releasenotes
by exceptionlessGenerate formatted changelogs from git history since the last release tag. Use when preparing release notes that categorize changes into breaking changes, features, fixes, and other sections.
tanstack-form
by exceptionlessUse this skill when building or modifying forms with TanStack Form and Zod validation. Covers createForm, field-level validation, error handling, and mapping ProblemDetails API errors to form fields. Apply when adding new forms, implementing validation logic, or handling form submission in the Svelte frontend.
foundatio-repositories
by exceptionlessUse this skill when querying, counting, patching, or paginating data through Foundatio.Repositories Elasticsearch abstractions. Covers filter expressions, aggregation queries, partial and script patches, and search-after pagination. Apply when working with normal query/count/patch/pagination repository code; reserve raw IElasticClient for migrations or index maintenance that cannot be expressed through repositories.
aspire-diagnostics
by exceptionlessUse when investigating a running Exceptionless Aspire app through resource state, logs, OpenTelemetry logs/traces/spans, metrics, browser telemetry, dashboard data, or telemetry export. Based on Microsoft's official aspire-monitoring workflow skill. Do not use for ordinary code reading, narrow edits, or normal build/test work.
shadcn-svelte
by exceptionlessManages shadcn-svelte components already used by the Svelte ClientApp. Use when adding/updating shadcn-svelte components, fixing shadcn component composition, consulting shadcn docs, or handling registry/CLI work. For ordinary Exceptionless frontend placement, Svelte, TypeScript, accessibility, or testing guidance, use frontend-architecture first.
exceptionless-dotnet
by exceptionlessUse this skill when configuring, integrating, documenting, or reviewing Exceptionless .NET clients. Covers package selection and setup for Exceptionless, Exceptionless.AspNetCore, Extensions.Hosting, Extensions.Logging, MVC, Web API, WebForms, WCF, WPF, Windows Forms, NLog, log4net, Blazor, and serverless; client configuration, appsettings/app.config/environment variables, self-hosted URLs, storage, queue flushing, events, log levels, server-synced settings, plugins, privacy/data exclusions, troubleshooting, and upgrades.

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

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.
