Build agents with a modern TypeScript stack. Mastra is an all-in-one framework for building AI-powered applications and agents.
Mastra is a TypeScript-focused author whose skills help AI agents build and maintain full application stacks, from agent, workflow, tool, memory and storage design through to documentation and CLI-driven API work. Their most-used skills cover production-grade frontend interfaces such as dashboards, landing pages and React components, as well as Mastra framework guidance and spreadsheet-driven agents that read, update and sync tabular data across tools like Google Sheets, Excel, Airtable and Notion. The skills also extend into engineering workflow, including pull request review, security checklists and reviewer-friendly HTML explainers for code changes.
