Built on the 20-year-old todo.txt standard plus a battle-tested CLI. It's a plain text file you own that never disappears between sessions.
Three properties most task tooling gives up at least one of. The skill keeps all three.
Plain text you own, surviving across sessions — unlike built-in agent memory that resets when the conversation ends.
No account, no integration, no heavy task app to set up. One file and a command — nothing to provision.
An open standard plus a simple CLI any agent can drive. Move the file anywhere; any tool can read it.
Capable tools exist — they're just built for a different job than a simple list your agent can carry between conversations.
The todo.txt format has been stable and documented since 2006 — a spec, not a vendor.
A command-line tool refined over a decade of daily real-world use. Your agent already knows CLIs.
Human-readable, diffable, and portable to anything that can open a text file. No lock-in.
