mdtask

mdtask

CLI task manager where Markdown is the single source of truth. No database, no server, no GUI.

Language

English is the project language — docs, commit messages, code comments, and communication.

Principles

Markdown is the data model

It is a structured table:

• line = record
• indent = block boundary
• inline tokens = columns (tags, priority, properties)

CLI is only an interpreter, never the owner of data.

Help, don't hinder

Every feature must reduce user effort, not add configuration burden. Derive what you can from existing data in files — don't ask users to maintain mappings, schemas, or config that the tool could figure out on its own.

Task Format

- [ ] EXMPL-123 Short task title		#feature !high @status:doing
  Description body goes here.
  Can be multi-line.

• ID: header in format [A-Z]+-\d+, globally unique
• Metadata (after title):
  • #tag — tags
  • !crit / !high / !low — priority (no tag = medium)
  • @key:value — properties
• Body: indented lines after header

Commands

mdtask list                  # list open tasks
mdtask list --all            # all tasks including done
mdtask view <ID>             # print full task block by ID
mdtask done <ID>             # toggle task [ ] ↔ [x]
mdtask open <ID>             # open task in $EDITOR at line
mdtask move <ID> <file>      # move task to another file
mdtask set <ID...> <tokens>  # add metadata to tasks
mdtask ids                   # auto-assign IDs to unidentified tasks
mdtask validate              # check task integrity

Stack

Node.js + TypeScript + ripgrep. Minimal dependencies.
