This commit introduced todo.txt-cli as a Docker container, wrapped in a simple t shell function that mounts your task directory and forwards arguments to todo.sh. Todo.txt’s beauty lies in its format: every task is a single line in a plain text file, with optional priority markers (A), projects +project, and contexts @context. No database, no sync service — just a file you can grep, sort, awk, or edit in any text editor. Wrapping it in Docker meant zero local dependencies while keeping the full power of shell-based task management one keystroke away.
