Summary / The 27 components

07 Task decomposition and planning

Turning a request into an ordered sequence of repository changes and checks.

Latest—not scored
Baseline— 
Live use—last 7 days

Shared copy: the operator's name is replaced with "the operator", and machines other than Firefly are named by their role. Nothing else is changed.

What is built now

Nothing in the harness. (Her runtime has a separate plan tool for her own work; it is not used here.)

What is missing

Requirement canonicalization, obligation decomposition and the plan graph.

Reviewer's read: Round 2; not started

SWE-bench tasks are single issues that mostly need one localized change, so a planner has little to plan on this benchmark. The spec's driver was removed in reconciliation (the workflow driver in 23 owns control). If planning comes back, it will need a multi-step benchmark to be measured at all.

How it is measured deferred

Needs a multi-change task set first; SWE-bench dev cannot show a planning gain.

Adoption rules shared by every arm: How the tests work.
