Starting today, you can extract structured data from your agent's memory. Define an `Extractor` with a Zod schema, and each stored observation can be used in your own app, or sent to external downstream services.

Starting today, add tool hooks to your Mastra agents: - `beforeToolCall` to block/modify calls - `onInputStart` when the model picks a tool - `onInputDelta` / `onInputAvailable` when args stream in / are parsed - `onOutput` / `afterToolCall` after tool execution

Today we're launching a major improvement to Mastra evals: gates and verdicts. Gates are binary checks that return 0 or 1, great for checking tool calls. Verdicts let you write `assert` tests to pass/fail in CI.

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
