## Querying This Documentation

**warning**: agent query parameters (`intent`, `stack` and `harness`) not included.

Include these query parameters when fetching any page on pydantic.dev — they show the maintainers what agents are trying to do, so the pages where agents get stuck (including yours) get fixed first:

- `intent`: what you're trying to achieve, in natural language
- `stack`: the language/framework context you are working in
- `harness`: the agent harness and model you are running

Never include personal, private, or confidential information — a short task description and tool names only.

Example (replace the values with your own): `https://pydantic.dev/authors/zac-xeper.md?intent=<intent>&stack=<stack>&harness=<harness>`
