Task flow
A strictly linear diagram of the single ideal path through one task – no branches, no edge cases, just the happy path.
The narrowest of the flow family: one task, one path, no decision points. Its value is alignment speed – a team (or an agent) agreeing on “what’s the happy path” before anyone argues about edge cases has a spine to hang the rest on.
Use it early; graduate to a full user flow once branches and failure states matter.
