63%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 well-organized and unusually rich in concrete interpretation standards, but its guidance stops short of executable: no example call to the `factor_analysis` tool and no code for the factor/return computation steps. Moving the combination methods and pitfalls into reference files would improve both progressive disclosure and conciseness.
Suggestions
Add a concrete example invocation of the `factor_analysis` tool (e.g. its call syntax with the three required parameters) so step 3 is executable rather than descriptive.
Move the Factor Combination Methods and Common Pitfalls sections into reference files (e.g. references/combination.md, references/pitfalls.md), keeping a one-line pointer in SKILL.md.
Provide a short code snippet for steps 1-2 (computing factor exposures and forward N-day returns into aligned CSVs), since the alignment precondition is the skill's most error-prone step.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and operational (threshold tables, tool parameters, a stated alignment precondition), with only minor over-explanation of concepts Claude already knows (e.g. the definitional sentence under Survivorship Bias), matching the 'efficient; minor instances of over-explanation' anchor; not 5 because the Common Pitfalls section runs long. | 4 / 5 |
Actionability | The parameter and output-file tables plus numeric IC/IR thresholds are concrete, but there is no actual invocation example for the `factor_analysis` tool and steps 1-2 (computing factor and return CSVs) have no executable code — the combination formulas are schematic rather than runnable, fitting the 'some concrete guidance but incomplete' anchor. | 3 / 5 |
Workflow Clarity | The five-step workflow is clearly sequenced with an explicit data-alignment precondition and interpretation criteria serving as pass/fail checkpoints before screening/combination; not 5 because there is no explicit verify step (e.g. checking CSV alignment) before invoking the tool. | 4 / 5 |
Progressive Disclosure | At ~135 lines with no bundle files, the single SKILL.md inlines substantial material (Common Pitfalls, three Factor Combination Methods) that belongs in separate reference files — 'some structure but content that should be separate is inline'; the under-50-line exception does not apply. | 3 / 5 |
