Overview

External tool documentation for the pre-release validation script provided by the Wandb Weave repository.

Description

The prerelease_dry_run.py script installs Weave from the git master branch, initializes a test project, creates and executes a traced function, and validates the recorded call data. It asserts that exactly one call is recorded with the correct inputs and output.

This is an External Tool Doc: it documents a standalone script, not a library API.

Usage

Run this script before starting the release process to validate that the current codebase produces a functional SDK.
