Mdt
Mdt is a command-line tool that lets agents and humans use large Markdown files as shared spaces.
Mdt is a command-line tool designed to let agents and humans use a potentially large Markdown file as a shared space for communication and shared state. It shows changes relative to a retained revision, helping agents avoid unnecessary rereading, token use, and distraction. The tool preserves exact source text and gives each observed version a revision, supporting reads, comparisons, and safe edits. Reads and comparisons can be paged within an output budget, and edits identify their baseline so unrelated concurrent changes survive while ambiguous targets are rejected. The command set includes read, diff, find, outline, replace, insert, history, forget, and feedback. Prebuilt archives are available for macOS and Linux on Apple silicon and Intel architectures.
