designing-experiments

Design experiments and quasi-experiments before analysis. Use when choosing study design, treatment/control structure, outcomes, assumptions, validation plans after scientific experiment failure, or which of DiD, ITS, synthetic control, or regression discontinuity fits the research question. For fitting models or estimating effects on existing data, use performing-causal-analysis instead.

Quality

Content

80%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 lean and well-structured with a concrete decision tree, but the failed-experiment recovery workflow would benefit from explicit validation checkpoints to fully sequence the risky recovery decisions.

Suggestions

Add an explicit validation checkpoint in Failed Experiment Recovery (e.g., 'Confirm the failure is an assumption violation, not a measurement error, before redesigning') with a validate-then-proceed decision rule.

Include one short worked example walking the decision tree from a research question to a chosen design, to lift actionability toward a 5.

Make the decision rule for continuing, revising, or stopping concrete (e.g., thresholds or explicit stopping criteria) so the recovery loop is executable.

DimensionReasoningScore

Conciseness

Lean body with no padding or re-explanation of known concepts (e.g., it does not define DiD); assumes Claude's competence and every line earns its place, matching the score-5 anchor.

5 / 5

Actionability

Provides concrete, executable decision rules mapping structure to method (e.g., 'With multiple controls: Synthetic Control') and method to assumption; minor gap is the absence of a worked example, and it is instruction-only so no code is expected.

4 / 5

Workflow Clarity

The decision framework is a clear sequenced Step 1-2-3 tree, but the Failed Experiment Recovery workflow lists steps without explicit validation checkpoints or a validate-fix-retry feedback loop, so checkpoints remain implicit.

3 / 5

Progressive Disclosure

Under 50 lines, no bundle files present, and content is organized into clearly headed sections — meeting the rubric's simple-skill exception for a top score.

Description

92%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 is specific, complete, and well-bounded, with explicit trigger phrasing and a clear hand-off to a sibling skill. Its only minor weakness is slightly less exhaustive synonym coverage in the trigger terms.

DimensionReasoningScore

Specificity

Lists multiple concrete actions (study design, treatment/control structure, outcomes, assumptions, validation plans) plus named methods (DiD, ITS, synthetic control, regression discontinuity) — comprehensive coverage matching the score-5 anchor.

5 / 5

Completeness

Explicitly answers 'what' (design experiments before analysis) and 'when' via a concrete 'Use when...' clause with specific trigger phrases, matching the score-5 anchor.

5 / 5

Trigger Term Quality

Strong natural terms ('study design', 'control', 'outcomes', 'experiment failure') plus named methods users cite, but missing some common synonyms/variants that would warrant a 5.

4 / 5

Distinctiveness Conflict Risk

Clear niche (pre-analysis study design) with an explicit boundary clause routing model-fitting to performing-causal-analysis, minimizing conflict risk.
