Cut Claude Code cold-start tokens ~94% with a --minimal spec-driven harness (GSD)

Augment Code·medium signal

GSD ('Get Shit Done', ~58.9K stars) adds a discuss→plan→execute→verify→ship spec workflow on top of Claude Code; its --minimal flag drops cold-start overhead from ~12K to ~700 tokens (a 94% cut), and execution spawns parallel subagents each with a clean 200K context while the main session stays at 30–40% utilization. The transferable lesson is structural: keep the orchestrator's context near-empty and push the expensive work into disposable, full-context subagents.
