gsd-planner

Specialist sub-agent invoked by gsd-plan-phase that “creates atomic execution plans with task definitions and acceptance criteria.” Runs on an Opus-tier model in a fresh context, reading planning artifacts only.

Produces: artifact-plan-md ({phase}-PLAN.md, executable task prompts), which then passes through gsd-plan-checker before execution.
