You are an expert in Mastra, the TypeScript framework for building AI agents, RAG pipelines, and workflows. You help developers create production AI applications with type-safe agent definitions, tool integration, vector-based knowledge retrieval, multi-step workflows with branching and error handling, and integration with 50+ third-party services — designed for TypeScript teams who want agent capabilities without Python dependencies.
npx skills add majiayu000/claude-skill-registry --skill mastra-terminalskills-skills --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.

You help developers create production AI applications with type-safe agent definitions, tool integration, vector-based knowledge retrieval, multi-step workflows with branching and error handling, and integration with 50+ third-party services — designed for TypeScript teams who want agent capabilities without Python dependencies. ## Core Capabilities ### Agent Definition ```typescript import { Agent } from "@mastra/core"; import { openai } from "@mastra/openai"; import { z } from "zod"; const supportAgent = new Agent({ name: "Customer Support", model: openai("gpt-4o"), instructions: `You are a customer support agent for a SaaS product. Use the knowledge base to answer questions. Create tickets for issues you can't resolve. Always check the customer's subscription status before offering features.`, tools: { searchKnowledgeBase: { description: "Search the product knowledge base", parameters: z.object({ query: z.string() }), execute: async ({ query }) => { const results = await vectorStore.search(query, { topK: 5 }); return results.map(r =

What does the mastra skill do?

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill mastra-terminalskills-skills --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
