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.

A well-structured, actionable analysis framework with concrete code, metrics, and checklists; it is concise and clearly sequenced, with only minor gaps in checkpoint explicitness and external reference organization.

DimensionReasoningScore

Conciseness

Dense, information-rich tables and code with little padding, though a few lines ('The most robust anomaly in equity markets') mildly over-explain context Claude largely already knows.

4 / 5

Actionability

Concrete formulas (SUE, breadth, dispersion), an executable guidance-scoring function, specific yfinance calls, and checklists; minor gaps such as score_guidance_change referencing object attributes that are not defined.

4 / 5

Workflow Clarity

Clear pre-earnings and post-earnings checklists sequence the analysis, plus a structured output format; this is a non-destructive analysis skill so the validation cap does not apply, but explicit checkpoints are still implicit rather than emphasized.

4 / 5

Progressive Disclosure

Well-organized with clear section headers in a single ~230-line file; no bundle files exist to externalize, and the sectioning keeps it navigable, though detailed tables and the output template could optionally be split into references.

Description

75%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.

A specific, well-scoped description with strong trigger terms and clear distinctiveness, but it lacks any explicit 'when to use' trigger guidance, which limits completeness.

Suggestions

Add an explicit 'Use when...' clause, e.g. 'Use when analyzing earnings surprises, analyst estimate revisions, or guidance changes for US/HK equities.'

Include a couple more natural trigger synonyms users might say, such as 'after-earnings drift' or 'estimate changes'.

Consider noting the data-source dependency (consensus feeds) in the description to set expectations.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'track analyst consensus changes, earnings surprise patterns, and management guidance shifts' — covering the domain comprehensively across revisions, guidance, and PEAD.

5 / 5

Completeness

The 'what' is clear and concrete, but there is no 'Use when...' clause or equivalent explicit trigger guidance, which per the rubric caps completeness at 3.

3 / 5

Trigger Term Quality

Strong natural keywords an analyst would say ('earnings estimate revisions', 'guidance analysis', 'earnings surprise', 'PEAD', 'post-earnings drift'), but a few common synonyms (e.g., 'after earnings', 'estimate changes') are absent.

4 / 5

Distinctiveness Conflict Risk

A clear niche (earnings revision/guidance/PEAD analysis for US/HK equities) with distinct triggers and minimal overlap with other skills.
