What happens when Plan Guardian detects a deviation?

Depending on the severity, it can log a notice, inject a warning into the agent's context, pause the work for human acknowledgment, or halt the process entirely for critical violations.

Can I customize the sensitivity of the monitoring?

Yes, you can configure sensitivity levels to 'relaxed', 'normal', or 'strict' via the guardian-config.json file, and even set specific sampling rates for different development phases.

Do I need to manually create the Plan Digest?

No, Plan Guardian can automatically generate a digest at the start of a pipeline using your PRD.md and ideation documents as primary sources of truth.

How does Plan Guardian detect drift in my project?

It uses a sampling mechanism that hooks into file writes and bash commands, evaluating these actions against a 'Plan Digest' to ensure they align with the project's defined goals and constraints.

How do I update the plan if my requirements change mid-development?

You can issue a manual command to 'Update plan digest' with the new details, which allows the Guardian to log the change and adjust its monitoring criteria accordingly.

分析と監視

Monitors development activities in real-time to detect and alert on deviations from project plans and architectural constraints.

Plan Guardian is an automated oversight agent designed to run alongside Claude during the development lifecycle to ensure work remains aligned with the original project scope. By sampling work-in-progress and comparing it against a structured plan digest, the skill identifies scope creep, architectural violations, and logic drift before they lead to costly rework. It provides a multi-level intervention system—ranging from silent logging to process halts—to keep development focused on the core problem statement and technical boundaries defined in your PRD.
