TunePrompt
Give prompt iteration a testable workflow.
A TypeScript CLI for organizing prompt tests and inspecting model outputs in a repeatable developer workflow.
Problem & context
Manual prompt experimentation makes it difficult to compare changes consistently. TunePrompt brings prompts and expectations into a developer-oriented testing workflow.
Workflow
The public repository documents initializing a test configuration, running tests from the CLI, and inspecting their results. Provider configuration is supplied through environment variables.
Engineering perspective
Repeatable inputs make prompt changes easier to discuss. Passing a prompt test is still only evidence about those inputs: it cannot establish general model reliability. Evaluation criteria need to reflect the intended task and include difficult examples.
Scope & limitations
This overview covers the documented open-source CLI. Cloud services, caching performance, adoption counts, and latency claims are not independently established here. The repository is the reference for supported commands and current capabilities.
