Skill Claude CodeCodex
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Skill Codex
Build, audit, extend, and package GitHub-ready Model Context Protocol servers for Mailosaur. Use when Codex needs to map Mailosaur's official API or Node.js client to MCP tools, add Mailosaur email/SMS/TOTP/preview workflows, validate tool schemas against current documentation, or prepare a Mailosaur MCP repository…
Skill Claude CodeCodex
Use this skill when you (an AI agent) need to orchestrate a multi-step goal by planning a DAG of tasks, executing them in dependency order, tracking state across turns, and optionally pausing for human approval — all through the dag-planner-mcp MCP tools you have available.
Skill Claude CodeCodex
Foundation work for Productive MCP v2 — refactors the API client, sets up the test harness, modernizes the server bootstrap, owns transports and release plumbing. Picks up M1 (foundation fixes), M2 (McpServer migration + elicitation + completion + ResourceLinks infra), and M7 (StreamableHTTP transport + 2.0 release).
Skill Claude CodeCodex
Research Atlas docs and source structure, recommend useful skills, discuss specs, and create approved skill assets.
Skill Claude CodeCodex
LeanLane — stop AI agents from over-building. Decision ladder, minimal diffs, prune review, MCP.
Skill Claude CodeCodex
Define Model Context Protocol terms precisely (host, client, server, resource, tool, prompt, sampling, elicitation, extension, SEP). Use when the user asks what an MCP term means or how MCP concepts relate.
Skill Codex
Operate AgentLink as a persistent, encrypted two-agent messenger. Use whenever AgentLink MCP tools are available, a peer agent is connected, or the task could benefit from asking, answering, or coordinating with a trusted peer agent through AgentLink.
Skill Claude CodeCodex
Coordinate material work with humans, Codex, Claude Code, and other active coding-agent sessions through one local room per Git project. Use it to announce bounded work, inspect active handles and worktree targets, report collisions or blockers, and post provenance-rich handoffs without treating chat as authority.
Skill Claude CodeCodex
Interactive design process to explore architecture, requirements, and user experience before writing code.
OpenSIN-Code/SIN-Code-MCP-Server-Builder-Skill
Skill Claude CodeCodex
MCP Server Builder — meta-skill that scaffolds new MCP servers (python-fastmcp / node-mcp / go-mcp). 8 tools: scaffold, templatelist, addtool, test, register, validate, publish, audit.
Skill Claude CodeCodex
Manage MCP servers with mcp-hub — discover/search servers, add and configure them from their docs, wire secrets to the OS keychain, reload, verify, and troubleshoot. Use when adding/removing/configuring an MCP server in mcp-hub, when the user says "add mcp to mcp hub", or asks how to find or manage MCP servers.

Skill Claude CodeCodex
Explicitly convene evidence-backed advisors from relevant local Codex task history for a decision, design question, or implementation choice.
Skill Claude CodeCodex
Paste the section below directly into the system prompt of any agent that should apply EFF automatically.
Skill Claude CodeCodex
Use when coordinating with other agents or humans through the AgentTalks channel - sending messages, asking open questions, claiming shared resources, or checking who is active before touching shared state.
SettleTop-Inc/CodeRoot-Authoring-MCP
Skill Claude CodeCodex
Use when starting to build a new MCP server, agent, skill, or prompt asset — captures the foundational asset record during the build via the coderoot-authoring MCP.

Skill Claude CodeCodex
Hand a task to Claude Code for a gentle, thorough second pass. Use when you'd like a collaborative second agent to investigate, review, or implement something in the current repo — for example "ask Claude to look at this", "get a second opinion from Claude", or "have Claude take a pass at this". Claude runs in the…
Skill Claude CodeCodex
Route Markdown documents, evidence-backed project facts, conversation history, personal memory, and reusable procedures without double-writing. Use when an Agent must search or write AFS documents, propose or retrieve governed facts, inspect evidence and Timeline, or choose the correct durable store.

Control OpenCode + Oh My OpenAgent TUI via terminal-use-mcp — vanilla OpenCode controls plus OmO-specific Tab/Prometheus, ultrawork, Team Mode.
Skill Codex
Orchestrate local ZCode, Kimi, Claude Code, Codex CLI, and Pi agents through Agent Gateway MCP. Use for low-cost routing, multi-agent comparison, failure escalation, visible terminal demos, safe worktree-based parallelism, or maintaining the gateway.
Skill Claude CodeCodex
Talk to another Claude chat through a shared room — on this machine or a different one — and pick up a conversation a previous chat left behind. Use when the person wants two chats to exchange messages, wants this chat to continue where another one stopped, mentions a room id — six words joined by dashes, like…
zinanga/motor-agentico-plugin-sdk
Skill Claude CodeCodex
Crea una "neurona" (plugin) para el Motor Agéntico siguiendo el estándar de la Zona de Plugins — o un artefacto standalone para quien no use el conector. Úsalo cuando alguien quiera añadir una pieza al Motor (un panel, una herramienta, un tema, una fuente de datos) sin tocar el núcleo ni saber cómo funciona por dentro.
Skill Claude CodeCodex
Build and iterate on MCP apps with custom UI views (user-generated apps) using the local MCP App Dev Kit. Covers the full local loop: brainstorm against UX guidelines, scaffold tools + views in the dev kit, persist data in a local Durable Object (DO SQL), run the dev server, expose it with ngrok, connect it to Claude…
Association-of-stupid-people/cocos-mcp-server
Skill Claude Code
Build MCP servers for LLM-external service integration. Use for FastMCP (Python), MCP SDK (Node/TypeScript), tool design, API integration, resource providers.
