56%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 delivers strong actionability through concrete get_cost_data() invocations and a well-sequenced 11-step workflow with a false-positive validation stage, plus a commendable all-math-in-code rule with security constraints. It is held back by heavy padding — a bloated 11-section output template and four overlapping reference-style sections that should be split into bundle files.
Suggestions
Move the Common Anomaly Types, Advanced Techniques, and Anomaly Detection Techniques sections into a reference file (e.g., references/anomaly-types.md) and keep only a one-line pointer plus the 2-3 most frequent types in SKILL.md, cutting the body roughly in half.
Compress the 11-section Output Format into a single worked example with severity levels and one template per report section, moving the full template to references/report-format.md.
Tighten Step 9 (rate-of-change) into an executable Python snippet consistent with Step 2's outlier code, defining thresholds and variable sources, and merge the four overlapping best-practices/tips sections into one.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The 620-line body is noticeably padded: an 11-section output template full of $X,XXX placeholders (~190 lines) plus overlapping back-matter sections ("Anomaly Detection Techniques", "Common Anomaly Types", "Advanced Techniques", "Tips for Effective Anomaly Detection") repeat concepts and re-teach what Claude already knows (z-score formula, percentage change). | 2 / 5 |
Actionability | Seven concrete get_cost_data() calls with real parameters (group_by, granularity, date_range, limit) and mostly executable Python snippets (Step 2 outlier detection, z-score/percentage techniques) give largely copy-ready guidance; minor gaps keep it below fully-executable — Step 9 is pseudocode, recent_costs is never defined, and baseline_costs = [...] placeholders remain. | 4 / 5 |
Workflow Clarity | The 11 steps are clearly sequenced (baseline → total → service → account → resource → region → usage → cross-dimensional → rate-of-change → security/waste → tags → output), with the False Positive Assessment serving as a validation checkpoint. It falls short of a 5 because validation exists only in the output format rather than as explicit in-workflow checkpoints or feedback loops. | 4 / 5 |
Progressive Disclosure | References to ${CLAUDE_PLUGIN_ROOT}/references/*.md are clearly signaled in "See Also", but ~300 lines of output templates, anomaly-type taxonomies, and advanced techniques are inlined in SKILL.md when they belong in reference files — no references/, scripts/, or assets/ bundle files exist to absorb them, so content that should be separate is inline. | 3 / 5 |
