Skill: planning

Standard/Full planning pipeline: Discover -> Classify -> Explore -> Decompose -> Detail -> Cross-cut -> Save -> Check -> Confirm -> Handoff

The plan is written in stages, not one shot: DECOMPOSE fixes the phase shape and seams, DETAIL fills one phase at a time with a reset between each, CROSS-CUT derives the whole-plan sections. Each stage writes to the file in place.

The plan is a contract between plan and build. It specifies WHAT and WHY at the strategic level, with explicit interfaces between phases.

Thinking effort: Planning benefits from max effort. If not already at max, suggest the user increase it before proceeding.

Create Progress Tasks

TaskCreate for each step, TaskUpdate with blockedBy to enforce ordering:

DISCOVER: Codebase search | DISCOVER: Questioning | CLASSIFY | EXPLORE | DECOMPOSE | DETAIL | CROSS-CUT | SAVE | CHECK | CONFIRM | HANDOFF

During DETAIL, add one sub-task per phase under it (one TaskCreate each), worked in DAG order.
