What problem does it solve? Starting a new development task without a clear plan leads to rework, unclear ownership, and integration failures. This Skill structures the kickoff phase by judging task scale, splitting work into assignable subtasks, dispatching them to the right executors, and defining integration and acceptance checkpoints. ## Core Features & Use Cases - Plan-mode judgment and task sizing: Automatically decides whether a task needs plan mode and whether it is small, medium, or large before any implementation begins. - Executor-based dispatching: Assigns subtasks to the main AI, Claude Code, Codex sub-agents, Antigravity, or humans based on task nature rather than even workload distribution. - Integration and acceptance orchestration: Enforces explicit task packages, handoff criteria, integration checkpoints, and final acceptance so subtasks do not silently fail to connect. - Use Case: When starting a new feature that touches core logic, UI configuration, and scene wiring, use this Skill to split the work into phases, assign core logic to Claude Code, parallel slices to Codex sub-agents, manual wiring to Antigravity, and reserve integration and acceptance for the main AI. ## Quick Start Ask the AI to use development-task-routing to judge whether your new task needs plan mode, split it into subtasks, and assign each part to the right executor.
