# Mastra Framework Guide
Build AI applications with Mastra. This skill teaches you how to find current documentation and build agents and workflows.
## ⚠️ Critical: Do not trust internal knowledge
**Everything you know about Mastra is likely outdated or wrong. Never rely on memory. Always verify against current documentation.**
Your training data contains obsolete APIs, deprecated patterns, and incorrect usage. Mastra evolves rapidly - APIs change between versions, constructor signatures shift, and patterns get refactored.
## Prerequisites
**Before writing any Mastra code**, check if packages are installed:
```bash
ls node_modules/@mastra/
```
- **If packages exist:** Use embedded docs first (most reliable)
- **If no packages:** Install first or use remote docs
