73%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 a well-structured, highly actionable operational document with clear sequencing, validation, and error recovery. Its weaknesses are moderate padding (textbook method explanations, an implementation checklist, a duplicated dependency table) and references to bundle files that do not actually exist.
Suggestions
Remove the 'Methods' concept explanations (t-SNE/UMAP/normalization definitions Claude already knows) and the 'Implementation Checklist' section, or move both to a reference file — this would recover the conciseness lost to padding.
Delete the inline 'Dependency Baseline' table (it duplicates dependencies.lock.tsv) or actually ship dependencies.lock.tsv and reference it in one line.
Fix dangling bundle references: either include the tests/ directory (test_skill.R, run_smoke_test.R, data/) that the Testing section depends on, or remove those commands; similarly resolve the tests/output validation commands against the shipped bundle.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body mostly uses tight, efficient tables, but it pads several sections: the 'Methods' section re-teaches what t-SNE and UMAP are ('t-SNE is a non-linear dimensionality reduction method that preserves local neighborhood structure'), the 13-item 'Implementation Checklist' is development meta-noise irrelevant to running the skill, and the 'Dependency Baseline' table duplicates dependencies.lock.tsv. This fits 'mostly efficient but includes some unnecessary explanation' rather than the 2 anchor, since the padding is a minority of the document. | 3 / 5 |
Actionability | The main path is fully executable: copy-paste install and usage commands, a complete arguments table, concrete input/output specs, and an error-code-to-solution table. However, the Testing section's commands reference tests/data/, tests/test_skill.R, and tests/run_smoke_test.R, and the Dependency Baseline section references dependencies.lock.tsv — none of which exist in the bundle — so those commands are not runnable as shipped, a minor gap consistent with the 4 anchor. | 4 / 5 |
Workflow Clarity | The 4-step workflow is clearly sequenced with an explicit validation step up front (Step 1: validate groups, samples, column alignment), error-to-solution feedback loops with re-run guidance ('Install dependencies first, then re-run to expose any file-related errors'), and post-run verification commands (ls of output dirs, wc -l on coordinate CSVs). This matches the 5 anchor: clear sequence with explicit validation and recovery loops. | 5 / 5 |
Progressive Disclosure | The 'When to Read External Files' table clearly signals one-level-deep references (references/algorithm.md, troubleshooting.md, cli-guide.md — all real files) by situation, which is excellent. Minor gaps keep it below 5: the body also points to nonexistent paths (tests/, dependencies.lock.tsv), and the full inline Arguments table duplicates content that belongs in the cli-guide reference. | 4 / 5 |
