AI coding assistant with a command tool and file editing by line id.
Minimal Claude Code alternative. Single Python file, zero dependencies, ~1200 lines. Inspired from nanocode by 1rgs.
bash runs a command (cmd.exe on Windows), with an optional timeout, working directory, or background mode. read pages through a file; with ids=true each line gets a short stable id, and replace, insert and delete edit by those ids, so edits are exact without repeating the old text. memory keeps project notes in .ucoder/ucoder.db.
