61%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 skill lays out a clear, well-organized analysis workflow with concrete artifact conventions, but it lacks executable code templates/examples and explicit validation loops for its batch and overwrite operations, which cap actionability and workflow clarity.
Suggestions
Add a short example SQL artifact (with the required purpose comment block) and a minimal Python viz script snippet so the artifact conventions are copy-paste ready.
Insert an explicit validation checkpoint after generating artifacts — e.g., re-run the query to confirm reproducibility and verify the image/CSV rendered correctly before finalizing, with a fix-and-retry loop.
Provide a brief README skeleton showing the required section order (Problem Statement, TL;DR, Cohorts Definition, step sections, Key Takeaways) so the summarization step is fully actionable.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence (no explanations of BigQuery or visualization basics), but the Cohorts Definition bullets are somewhat dense and could be tightened, so 4 not 5. | 4 / 5 |
Actionability | Guidance is concrete on file locations and formats ('.sql file in /assets/queries/', 'save both the script and the output image'), but it provides no example SQL comment-block template, viz script, or README skeleton, leaving key execution details missing. | 3 / 5 |
Workflow Clarity | The six-step sequence is clear and includes a plan-approval checkpoint, but batch artifact creation and the destructive overwrite step (step 5) lack an explicit validate→fix→retry loop, so the destructive/batch cap of 3 applies. | 3 / 5 |
Progressive Disclosure | A single self-contained SKILL.md with clean section headers and a directory-tree example; no nested or buried references, but it is over 50 lines with all content inline, so 4 rather than 5. | 4 / 5 |
