Evaluating skill definitions for context efficiency involves assessing line count, load budget, and density to ensure a SKILL.md is efficiently composed and avoids bloated execution guidance.

The skill optimization guideline requires definitions to remain under 200 lines. Evaluation criteria align with this limit to identify sections for decomposition and prevent excessive context load costs.

To gate content behind child docs, identify always-load versus scenario-specific content within skill definitions. Flag sections that should be gated to reduce redundant context and optimize line density.

Detect duplication in skill definitions by checking for misalignment with related skills and project documentation, flagging redundant content to ensure assistants only load necessary, non-repeated information.

Check allowed-tools alignment during quality reviews and architecture audits. Ensuring skill definitions match their operational scope prevents unnecessary context loading and execution overhead.
