What problem does it solve? Running end-to-end tests for the Vercel AI SDK integration requires juggling Infisical secrets, environment variables, and choosing between a local stack and production, which is error-prone without clear guidance. ## Core Features & Use Cases - Dual Environment Testing: Run tests against production OpenRouter or a local development stack with the correct environment overrides. - Secrets Management: Authenticate with Infisical universal auth to inject the required API keys and test scopes. - LLM Flakiness Guidance: Diagnose failures caused by non-deterministic model behavior, such as models skipping tool calls. - Use Case: A developer modifies the Vercel AI SDK integration and needs to verify tool-calling behavior against production before merging, using a production API key and the correct test invocation. ## Quick Start Run the Vercel AI SDK e2e test for a specific test directory against production using my Infisical credentials and OpenRouter API key.
