💻 How They Work
Aider Workflow

$ aider
Aider> /add src/api.py src/models.py
Aider> Add error handling to the API endpoints
✓ Applied changes to src/api.py
✓ Committed: "Add try-catch blocks to API endpoints"
Aider reads your code, applies edits, and auto-commits. You can undo with git or ask for changes.
Continue Workflow
Open Continue in VS Code sidebar and chat about your code:
You: Refactor this function to use async/await
Continue: Here's the refactored version:
[Shows diff inline in editor]
