    Incredibly excited to share file-based agents in Mastra 🔥 Write the prompt in instructions.md, add .ts files in tools/ to define tools by filename, and place subagents in subagents/ Need a new capability? Just add another file

    We’ve spent years building integrations with some of the best in the business. Organized them all into one tidy page so you can see all your options (and hopefully your stack) at a glance! Who should we integrate with next? 👀

    Mastra is built to work with whatever stack you're already running. Check out all 80+ integrations at mastra.ai/integrations.
