gsd-mode-selector

12

sergei-aronsen/claude-code-toolkit

Skill Claude CodeCodex

Use when user requests work via natural language ("fix this", "add feature X") — selects appropriate GSD command (gsd-fast / gsd-quick / gsd-plan-phase) based on risk and scope, prevents using heavyweight pipeline for trivial work.
