Living Spec gives engineers and product teams the context they need throughout development. The spec becomes a shared context layer for agentic development.
Goal: a room a kid can actually play in. Links: Floor and turf Order turf Drawing: arena-layout
Decision (rev 38): skip the pressure adhesive. Tape between the turf and foam blocks held fine.

AI and agents now write code faster than any team can capture why. That intent lives in the spec, and the moment it drifts from what you are actually building, everyone is guessing again.
Specs end up spread across docs, tickets and READMEs that nobody quite trusts. Two sprints later they describe software that no longer exists.
Coding agents are only as good as their context. Without the spec they redo yesterday's decisions, badly.
The why ends up in chat threads, meeting notes and somebody's head. By the time you need it, nobody can find it.
Pages, tasks, drawings and files in one living document. Structured enough for a team, readable by an agent.
Connect Claude, or any MCP client, and your agents read the relevant spec as context. They work from the same source of truth your team does and write their progress back on a branch you review, so the spec stays current as they work. Nobody has to stop and write it up by hand.
