78%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is an efficient, well-structured, self-contained specification: concrete factor formulas, parameter defaults, an explicit signal convention, and pitfalls that act as operational checkpoints. The main gaps are the undefined IC-weighted scoring variant referenced in the description and the lack of an explicit output-validation step in the workflow.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean: terse numbered steps, compact tables for factors and parameters, and a short pitfalls list with no concept padding. Minor over-explanation could be trimmed (e.g., "Z-score normalization (subtract mean, divide by standard deviation)" and "1/PE (the larger, the cheaper)" restate things Claude already knows), keeping it just below the 5 anchor and clearly above the 3 anchor's noticeable slack. | 4 / 5 |
Actionability | Concrete, implementable guidance throughout: named factors with formulas ("Today's volume / N-day average volume", "Return over the past N days"), parameter defaults (top_n=3, rebalance_freq=20), exact weighting ("weight = 1/N for each"), and a defined signal convention ("1/N = selected... 0 = not selected"). It is not a 5 because "IC-weighted" scoring is referenced in the frontmatter but never defined in the body, leaving one path underspecified; it is well above the 3 anchor since the steps are executable as written, not pseudocode. | 4 / 5 |
Workflow Clarity | The Signal Logic section gives a clear numbered 4-step sequence (calculate → standardize → composite → rank/select), and the Common Pitfalls section functions as implicit checkpoints (minimum 3 stocks for Z-scores, hold signal between rebalance dates, align factor directions before standardization, normalize weights). Not a 5 because there is no explicit validate/verify step (e.g., asserting weights sum to 1 or that the cross-section has enough names before ranking); not a 3 because the sequence is coherent and checks are stated, just not framed as a validate-and-retry loop. | 4 / 5 |
Progressive Disclosure | The skill is a compact (~50-line) self-contained body with no bundle files and no external references; sections are well-organized (Purpose, Signal Logic, Built-In Factors, Parameters, Common Pitfalls, Dependencies, Signal Convention). Per the rubric's simple-skill guidance, a short skill with no need for external references and well-organized sections earns a 5 — nothing is inlined that belongs in a separate file. | 5 / 5 |
