Implements a structured checkpoint system for AI agents to request human decisions without making assumptions.
The User Input Protocol skill provides a robust framework for Claude to handle ambiguity by pausing at critical decision points rather than guessing. It defines a standardized AWAITING_USER_INPUT format that presents context, multiple labeled options with their implications, and agent recommendations. This skill is essential for managing architectural trade-offs, business rule conflicts, and destructive actions, ensuring the developer remains in control. It includes advanced patterns for subagent state preservation, allowing background tasks to save progress and resume instantly once a decision is provided, and offers urgency classification for automated pipelines.
Key Features
012 GitHub stars
02State preservation and resumption patterns for subagents and background tasks
03Prescriptive options (2-4) with detailed implications instead of open-ended questions
04Urgency classification (blocking, next-review, informational) for factory workflows
05Decision batching to group related questions and reduce developer interruption
06Structured AWAITING_USER_INPUT checkpoint format for clear human communication
Use Cases
01Gaining explicit confirmation before performing destructive actions like file deletion
02Resolving architectural trade-offs where multiple valid implementation paths exist
03Clarifying ambiguous business requirements during complex feature development
