Uncut

Uncut is a headless coding-agent harness for shell pipelines, CI jobs, and containers.

Uncut is a tiny coding-agent harness designed for shell pipelines, CI jobs, containers, and agent experiments. It provides four tools for reading files, writing files, replacing text, and running commands. The software sends the entire conversation on every model call without context compaction, summarization, or sliding windows. It works with OpenAI-compatible Chat Completions endpoints and local servers, using plain stdin and stdout. It targets developers and testers who need a transparent agent framework that exits with an error rather than presenting a partial answer as success.
