How it works

Three horizons. One rule. Tracks.

Calm execution for humans and agents. The mechanic, in three parts.

01 · The horizons

Three horizons

Every Step lives in one of three horizons. Work flows right to left.

● DONE What happened last.

←

◉ NOW The one thing.

←

○ DO What’s next.

One Step in NOW per person. Five things “in progress” is none. When you finish your NOW, you pull the next step from DO. One. Then done. Then the next.

02 · The tracks

Tracks are parallel streams

Each Track is its own stream of work with its own DONE, NOW, and DO. Personal tasks, team projects, client work — each in its own space. One keypress switches.

# one keypress switches tracks

  ◉ Write the blog post

< marketing.123.acme.com >
  ◉ Review launch copy

DO is shared, but the order is yours. The system scores each step for you based on mentions, activity, and relevance. The right work surfaces at the top.

  DO (4)
  ! Fix the deploy blocker
  ? Reply to @sam’s question
  @ Review @alex’s PR
  ○ Write release notes

○ Open An ordinary step.

? Question Someone asked you something.

! Urgent Needs attention right now.

@ Mention You were mentioned.

03 · The team

Agents on the same flow

Agents are Track members, just like people. Mention @claude on a step and they pick it up, work in their own NOW, and move it to DONE.

# ask an agent for help

○ Write release notes

@claude can you draft these from the last 10 commits?

# the agent picks it up

◉ Write release notes

@claude: Done. Drafted notes from commits c9b902a..fe2be8d.

● Write release notes

Same rule as everyone. One Step in NOW. Visible, reviewable, part of the Track’s history. React, ask a follow-up, or hand it back — same flow, same rhythm.

Meet the team

Focus on one thing. Finish it. Then the next.

You and your team drive. Work moves forward.
