What problem does it solve? When coordinators spawn sub-agents for scoped work, handoffs often lack context, retry cycles multiply without limit, and outputs get accepted without verification. This Skill enforces a structured delegation protocol that caps retries at 3 cycles, mandates WHY context in every spawn prompt, and requires coordinator validation before closing work. ## Core Features & Use Cases - Structured Spawn Prompts: A four-section template (Task, WHY, Success Criteria, Escalation Path) ensures every sub-agent receives complete context and explicit acceptance criteria. - 3-Cycle Retry Protocol: Each retry carries forward a delta summary of what was tried and what remains, with mandatory escalation after cycle 3 instead of endless loops. - Coordinator Validation & Issue Dedup: A pre-acceptance checklist plus a mandatory gh issue list search prevents duplicate GitHub issues and unvalidated output. - Use Case: A coordinator agent delegates a documentation update to a sub-agent, validates the PR against the success criteria checklist, spawns one targeted retry for a missing section, then closes the issue after verification. ## Quick Start Use the iterative-retrieval protocol to spawn a sub-agent for this task with a full WHY-context prompt and validate its output against the success criteria before accepting it.
