goldrush-foundational-api
by covalenthqGoldRush Foundational API — REST API for historical and near-real-time blockchain data across 100+ chains. Use this skill whenever the user needs wallet token balances, transaction history, NFT holdings, token prices, token approvals, cross-chain activity, block data, portfolio value tracking, or any on-chain data query via REST. This is the default skill for blockchain data lookups, portfolio dashboards, tax tools, compliance checks, block explorers, and any application that fetches historical or current chain data. If the user needs real-time streaming or WebSocket push data, use goldrush-streaming-api instead. If the user needs pay-per-request access without an API key, use goldrush-x402 instead.
goldrush-x402
by covalenthqGoldRush x402 — pay-per-request blockchain data access using the x402 protocol (HTTP 402 Payment Required). Use this skill whenever the user is building an AI agent that needs blockchain data without API keys, wants wallet-based micropayments for on-chain data, needs autonomous or no-account access to the GoldRush API, mentions the x402 protocol, or wants no-signup/no-onboarding blockchain data access. This is the right skill for autonomous agents, serverless applications, and prototyping without onboarding. Provides access to 60+ Foundational API endpoints through a transparent reverse proxy with stablecoin payments on Base. If the user needs a traditional API key with monthly billing, use goldrush-foundational-api instead. If the user needs real-time streaming data via WebSocket, use goldrush-streaming-api instead.
goldrush-cli
by covalenthqGoldRush CLI — terminal-first blockchain data tool with MCP support for Claude Desktop and Claude Code. Use this skill whenever the user wants to query blockchain data from the command line, stream DEX pairs or wallet activity in a terminal, set up GoldRush as an MCP tool provider, or run quick one-off queries without writing code (e.g., 'check a wallet balance', 'what's the gas price', 'search for a token'). Also use this when the user mentions 'goldrush' CLI commands, 'npx @covalenthq/goldrush-cli', or MCP integration with GoldRush. The CLI is the fastest path for ad-hoc blockchain lookups from the terminal. If the user needs programmatic API access in an application, use goldrush-foundational-api or goldrush-streaming-api instead. If the user needs pay-per-request access without an API key, use goldrush-x402 instead.
goldrush-streaming-api
by covalenthqGoldRush Streaming API — real-time blockchain data via GraphQL subscriptions over WebSocket. Use this skill whenever the user needs live price feeds (OHLCV candles), real-time DEX pair monitoring (new pairs, liquidity updates), wallet activity streaming, decoded swap/transfer events, token search, trader PnL analysis, or any sub-second latency blockchain event push. This is the right skill for trading bots, live dashboards, alerting systems, copy-trading, DEX sniping, and real-time analytics. Also covers one-time GraphQL queries for token discovery and profitability analysis. If the user needs historical data, batch queries, or paginated REST results, use goldrush-foundational-api instead. If the user needs pay-per-request access without an API key, use goldrush-x402 instead.

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.
