 1. Check the [issues](https://github.com/wandb/weave/issues) and [PRs](https://github.com/wandb/weave/pulls) to see if the feature/bug has already been requested/fixed. If not, [open an issue](https://github.com/wandb/weave/issues/new/choose). This helps us keep track of feature requests and bugs!

+2. If you're having issues, the best way we can help is when you can share a reproducible example.
+   1. In general, it's helpful use this format:
+      ```
+      <short description of the issue>
+      <link to your project>
+      <system info, including weave version, python version, and OS>
+
+      <reproducible code snippet>
+
+      <any other info you think is relevant>
+      ```
+   2. For SDK issues, a reproducible script like [example_error_script.py](examples/contributing/example_error_script.py) is helpful.  We use `uv` which can run the script with the dependencies included.  If you know the dependencies, you can add them to the script.  [See the `uv` docs for more details](https://docs.astral.sh/uv/guides/scripts/).
