Citrine

Minimalist, plaintext, project-based todo CLI. Creates .citrine files in your project directory — human-readable, git-friendly, and AI-agent-parseable.

Install

Download a binary from releases or build from source:

cargo install --path .

Quick Start

citrine init
citrine add "Implement caching layer"
citrine add "Fix mobile layout" --local
citrine list
citrine set a4f9 progress
citrine done a4f9
citrine rm a4f9

Commands

Command	Description
citrine init	Initialize citrine in the current directory
citrine add <description> [--local]	Add a new task (--local for .citrine.local)
citrine list [--status <s>] [--local]	List tasks, optionally filtered
citrine set <hash> <status>	Change task status
citrine done <hash>	Mark task as done (shorthand for set <hash> done)
citrine rm <hash>	Remove a task

Statuses: todo, progress, blocked, done

Hashes can be partial — a4 works if it's unambiguous.

Metadata

Append @tag or @key:value to any task. Free-form, not validated. @completed:YYYY-MM-DD is auto-added when marking a task done.

Files

• .citrine — shared project tasks, commit to git
• .citrine.local — personal tasks, gitignored

Both share the same hash namespace. citrine list merges both by default.
