Mastra Agent Framework

Build TypeScript AI agents and workflows with Mastra. Covers agents vs workflows, tools, memory, and RAG, with strategies for looking up current docs and verifying API signatures against the installed version.

This skill develops applications on the Mastra TypeScript framework. It distinguishes agents from durable workflows, wires tools and memory, adds RAG over your data, and enforces a documentation-first approach — checking embedded and remote docs to use current APIs from the installed version rather than outdated signatures.

When to use

Use when building AI agents or typed workflows in TypeScript with Mastra, including tools, memory, and RAG.

Examples

Agent with tools and memory

Build a stateful assistant

Build a Mastra agent with a weather tool and conversation memory, and expose it from a Next.js route

Typed workflow

Chain steps deterministically

Create a Mastra workflow that fetches a URL, summarizes it, and stores the result, with typed inputs and outputs
