What problem does it solve? Delegating work to sub-agents like fae and rook without clear operating rules leads to lost context, zombie tasks, wasted concurrency slots, and unrecoverable parallel-workspace corruption. This Skill defines the mandatory tool-level protocol for safe, notification-driven sub-agent collaboration. ## Core Features & Use Cases - Delegation Tool API Reference: Documents wopal_task, wopal_task_output, wopal_task_reply, wopal_task_abort, and wopal_task_finish with exact parameters and state-dependent behavior. - Task Lifecycle Management: Defines the running/idle/waiting/stuck/error state model with decision trees for handling IDLE, STUCK, and ERR notifications without polling. - Parallel Workspace Protection: Provides a mandatory prompt block forbidding git stash, checkout, reset, and other commands that could destroy other agents' uncommitted changes in shared working trees. - Use Case: When you ask the agent to "let fae implement this feature" or "have rook review my commit", this Skill loads first so the delegation prompt includes precise paths, the correct review contract (commit range vs working tree), and reuse-versus-recreate rules based on context usage thresholds. ## Quick Start Ask the agent to delegate a code implementation task to fae or a code review to rook, and this Skill will govern how the task is launched, monitored, and finished.
