# Tested functions

Part of Harness tools by Baltor.

One upstream Python function at a time, copied with the code it needs and a test: validators, parsers and formatters your agent can import without adding a dependency.

## What to watch for

- A copied function keeps its upstream licence beside it.
- Validators answer true or false; parsers should also say why they refused.
- Pin the upstream commit so the copy can be compared later.
