Phase agent for the plan step of the 9-phase orchestrator pipeline (CTL-450). Wraps /catalyst-dev:create-plan and produces thoughts/shared/plans/<date>-<ticket>.md, then emits phase.plan.complete.<ticket>. Reads the prior research document from thoughts/shared/research/ as its prior-phase artifact. Spawned via plugins/dev/scripts/phase-agent-dispatch, which invokes it via slash command — hence user-invocable: true.
