Usually an architect or an engineering lead, with the developers who build it
A written spec turned into a landscape, an app with a target sketch, sequenced work items and compiled skills, and a first slice built in an empty repo.
A new project starts as a document. Someone has to turn it into systems, an order of work, and the conventions the code should follow, and by the time the first developer opens an empty repository most of that lives in the architect's head and a slide.
With coding agents, one engineer can take a spec to a working slice in a day. The plan, the reasons and the order of work still have to be visible to everyone else who carries the project after them.
The same steps the product’s playbook walks. Each one shows the screen at that moment.
The workspace plugin reads the spec and asks only what it leaves open. It draws the systems you intend to build on the root board, each one planned, with the actors and services around them, and commits it with a reason.

One round of questions binds the app to the repository that is coming, picks the branch, and draws a target sketch on its board from the spec: the apps, the components it names, the edges between them, before any code exists.

The plugin drafts the rest of the spec's phases as work items under an epic, each with its exit condition and what it waits for, and proposes compiled skills for the stack. The architect hands the drafts off to the developers.

In the empty repository the developer's agent writes the compiled skills, claims the first work item, reviews it against the code, plans each element where the next sync can match it, and implements it, recording the project's own checks as evidence.

Back on the board everyone sees the same state: the first work item completed with the developer's note and commit, naming what still needs a person, and the rest open in the order the plan set.

End proofDone when the first work item is completed in the repository, and the rest are open in build order for the team.
A target architecture drawn once in a deck, with the order of work in a spreadsheet and the conventions in a wiki nobody's agent reads.
An empty repository, and nothing to browse until the code exists.
The spec turned into a landscape, an app with a target sketch, sequenced work items and compiled skills, so the first slice is built from the plan and the board shows what was built against it.
