You can evaluate and iterate on Claude Code skills by running an eval loop with test-case prompts, measuring trigger evaluation accuracy, and grading evidence to validate deterministic skill behavior. This process helps refine trigger descriptions and SKILL.md structure iteratively.

Building a new Claude Code skill involves turning user intent into a well-structured SKILL.md with proper trigger logic. You then run realistic test prompts to confirm triggering behavior and iterate on the instructions based on measured results.

Benchmarking Claude Code skill performance uses automated grading, quantitative pass-rate tracking, and variance-aware analysis. This benchmark aggregation measures whether Claude triggers correctly and produces intended behavior across representative user queries.

Improving existing skills uses an eval-and-iterate loop that measures whether Claude triggers correctly and produces intended behavior. The process applies trigger evaluation and grading evidence to refine trigger descriptions without rebuilding the entire skill.

Yes, test-case prompts are required to validate deterministic Claude Code skill behavior. The eval-and-iterate loop uses representative user queries to measure trigger accuracy, grade evidence, and optimize descriptions for reliable skill activation.

Incorrect triggering happens when trigger descriptions lack precision. Running trigger evaluation with test-case prompts and iterating on the SKILL.md structure using grading evidence helps identify mismatches and improves triggering accuracy across representative queries.
