67%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.
A well-structured, highly actionable skill body with good progressive disclosure and a validated workflow. The main weaknesses are repeated explanatory content (conciseness) and references to bundled test data that does not actually exist in the package.
Suggestions
State the 'alpha=0 ridge writes empty selected_features.csv' behavior once (e.g. in the Output Files table) and remove the duplicate explanations in the Automatic Alpha Selection and Feature Selection Rule sections to recover tokens.
Either add a tests/data/ directory with the sample expression_matrix.csv, groups.csv, and genes.csv referenced by the Testing and cli-guide sections, or rewrite those commands to use placeholder user-supplied file paths so they are runnable as written.
Drop the 'Last updated: 2026-04-20 | Version: 1.0.0' footer (or move version info into a deprecated/changes section), and trim the Methods paragraph that re-explains L1/L2 elastic-net penalties Claude already knows.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly efficient tables and command blocks, but the 'alpha=0 ridge → empty selected_features.csv' note is stated three times (Output Files table, Automatic Alpha Selection, Feature Selection Rule), the Methods section restates the L1/L2 elastic-net concept Claude already knows, and a time-sensitive 'Last updated / Version' footer adds noise. | 3 / 5 |
Actionability | Fully parameterized, copy-paste-ready Rscript invocations cover first-run, fixed-alpha, conservative-lambda, and custom-label cases plus a complete arguments table. The one gap is the Testing section, whose commands target tests/data/* files that are not present in the bundle. | 4 / 5 |
Workflow Clarity | A clearly sequenced four-step Workflow opens with an explicit 'Step 1: Validate Input' checkpoint (existence, empty-data, column, sample-match, out-of-scope label rejection) and the Error Handling table provides a cause→solution→read-more feedback loop, so the batch-operation cap at 3 does not apply. | 4 / 5 |
Progressive Disclosure | The 'When to Read External Files' table gives well-signaled, one-level-deep navigation to references/algorithm.md, cli-guide.md, and troubleshooting.md (all present in the bundle), with detail appropriately split out; the dangling references to a non-existent tests/data/ directory are the main organization gap. | 4 / 5 |
