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, actionable procedure with concrete tool calls, clear step sequencing, and properly signaled external references. Its main cost is token weight: heavily repeated query blocks and overlapping patterns/tips sections inflate the body where a dimension reference table plus a couple of canonical examples would carry the same information.
Suggestions
Collapse the twelve near-identical get_cost_data blocks in Steps 2-3 into one canonical example plus a small table mapping dimension (service, account, cloud provider, region) to its FQDID — that alone would remove roughly 60 lines without losing any information.
Move the 'Common Analysis Patterns', 'Advanced Techniques', and detailed output-format templates into a reference file linked from the body, keeping SKILL.md as a lean overview with the query pattern and output summary.
Add an explicit sanity checkpoint after Step 2 (e.g., verify returned item count against the limit before computing contribution percentages, so truncated results aren't reported as complete totals).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is operational rather than explanatory — it doesn't teach concepts Claude already knows — but it is noticeably repetitive: Steps 2 and 3 present twelve nearly identical get_cost_data blocks that differ only in the group_by dimension, and the 'Common Analysis Patterns', 'Tips', and 'Best Practices' sections restate combinations already shown. This fits anchor 3 ("Mostly efficient but includes some unnecessary explanation or could be tightened") better than anchor 4, since a dimension-to-FQDID table could replace most of the query blocks. | 3 / 5 |
Actionability | Concrete, copy-paste-ready tool invocations with exact parameters (group_by FQDIDs, cost_type, limit, filters with ! and & operators) cover the common cases, and the output format section gives a concrete table schema. It falls short of anchor 5 only in that Step 6's percentage/cumulative calculations are described as a numbered list rather than shown as the mandated Python script, and the prerequisite skill's loading is directed but not shown — minor gaps per anchor 4. | 4 / 5 |
Workflow Clarity | A clear 7-step sequence runs from request clarification through querying, breakdown, calculation, and optional trend context, with four named analysis patterns for orientation. This is read-only analysis with no destructive or batch operations, so the validation-cap does not apply; it sits at anchor 4 ("Clear sequence with most checkpoints present; minor validation gaps") rather than 5 because there are no explicit result-sanity checkpoints (e.g., confirming the limit wasn't truncated before computing percentages). | 4 / 5 |
Progressive Disclosure | No bundle files exist in this skill (references/, scripts/, assets/ are all absent), and the body leans on clearly-signaled, one-level-deep plugin references in the 'See Also' section (best-practices.md, cloudzero-tools-reference.md, error-handling.md, dimensions-reference.md, cost-types-reference.md) plus one inline pointer in Best Practices. Section headers are clean and navigation is easy, matching anchor 4; it misses anchor 5 because substantial inline material (four analysis patterns, advanced techniques, and the detailed output-format templates) would sit more appropriately in reference files given the body's ~330 lines. | 4 / 5 |
