Quality

Content

75%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a well-organized, efficient reference that balances inline guidance with clearly signaled one-level-deep bundle references. It provides concrete, actionable artifacts throughout and a clear phased workflow with validation checkpoints.

DimensionReasoningScore

Conciseness

Efficient use of tables, checklists, and templates with minimal padding; a few tutorial-style restatements (e.g., the peeking explanation) could be trimmed, keeping it just below fully lean.

4 / 5

Actionability

Provides a concrete hypothesis template, sample-size tables, calculator links, decision tables, and checklists; for an instruction-only skill the guidance is actionable, with only minor gaps in executable specificity.

4 / 5

Workflow Clarity

Clear phased sequence (assess, hypothesize, design, implement, run, analyze, document) with a pre-launch checklist, during-test DO/Avoid, and an analysis checklist providing most validation checkpoints.

4 / 5

Progressive Disclosure

Body is a well-structured overview with clearly signaled, one-level-deep references to two real bundle files (sample-size-guide.md, test-templates.md); minor organization gaps versus an ideal split keep it just under 5.

Description

66%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description clearly states capabilities and domain but lacks an explicit 'Use when' trigger clause, capping completeness. It is specific and distinctive but slightly underuses the natural-synonym trigger terms that users would say.

Suggestions

Add an explicit 'Use when...' clause naming concrete trigger phrases (e.g., 'A/B test,' 'split test,' 'which version is better,' 'how long should I run this test').

Expand trigger terms in the description itself to include synonyms like 'split test' rather than relying on the body for them.

DimensionReasoningScore

Specificity

Lists several concrete actions ('Plan, design, or implement') and explicit domains (methodology, statistical significance, metric selection), with only minor gaps versus a fully exhaustive action list.

4 / 5

Completeness

Has a clear 'what' but no explicit 'Use when...' clause; per the judging guidelines, a missing explicit trigger guidance caps completeness at 3 even though the 'what' is clear.

3 / 5

Trigger Term Quality

Includes natural terms 'A/B test' and 'experiment', but the description itself omits common synonyms like 'split test' that appear only in the body, leaving a few natural terms missing.

4 / 5

Distinctiveness Conflict Risk

A/B testing with statistical-significance framing is a clear niche with only minor overlap risk against related analytics/CRO skills noted in the body.
