What is the 80% rule in Skill Refiner?

The 80% rule is a logic-driven framework that keeps core instructions used in the majority of tasks within the main SKILL.md while moving infrequent, supplementary details to reference files to save tokens.

Can Skill Refiner validate tool security?

Yes, during the validation phase, it reviews 'allowed-tools' scoping to ensure the principle of least privilege is applied, matching tool access strictly to the skill's functional requirements.

How does the Movement Pattern prevent data loss?

It enforces a strict sequence where new content must be created and linked in the destination before the old source is deleted, ensuring no instructions are lost during reorganization.

Does this work on installed Claude plugins?

No, Skill Refiner is designed for project-based and user-space skills. It specifically blocks editing of installed plugins in the cache to prevent breaking core system functionality.

What happens during a validation report?

The skill generates a systematic report covering seven phases: file inventory, content audit, metadata verification, line-count checks, reference integrity, tool scoping, and trigger testing.
