Uses ROADMAP.md phase discovery and Skill() flat invocations for each phase command. After all phases complete: milestone audit → complete → cleanup.

Creates/Updates:

.planning/STATE.md — updated after each phase
.planning/ROADMAP.md — progress updated after each phase
Phase artifacts — CONTEXT.md, PLANs, SUMMARYs per phase

After: Milestone is complete and cleaned up.

Project context, phase list, and state are resolved inside the workflow using init commands (gsd-sdk query init.milestone-op, gsd-sdk query roadmap.analyze). No upfront context loading needed.
