78%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 content is highly actionable with comprehensive executable SQL and a clear step sequence, but it is a monolithic single file that inlines material better suited to separate reference files and carries some general-knowledge padding.
Suggestions
Split the inlined API Reference (deprecated→new parameter and function mappings) and Schema Best Practices Do's/Don'ts into separate reference files (e.g. references/api-migration.md, references/schema-best-practices.md) and link to them from SKILL.md to improve progressive disclosure.
Consolidate the repeated row-density guidance (currently restated in the segment_by, order_by, and sparse_index sections) into a single location to reduce token redundancy.
Turn Step 11 into an explicit validate-and-retry feedback loop (e.g. if verification shows unexpected uncompressed chunks or missing policies, fix the policy and re-run the verification queries) to strengthen the workflow's validation checkpoint.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient and dense with actionable SQL, but includes some padding Claude already knows — the generic Schema Best Practices Do's/Don'ts (e.g. 'Use TIMESTAMPTZ NOT timestamp', 'Use NOT EXISTS NOT NOT IN') — and repeats the row-density guidance across three sections. | 4 / 5 |
Actionability | Fully executable, copy-paste-ready SQL throughout — CREATE TABLE with real tsdb options, add_retention_policy, continuous aggregates, refresh policies, compression, and verification queries covering the common cases. | 5 / 5 |
Workflow Clarity | Steps 1–11 are clearly sequenced with 'Good test' checkpoints, user-confirmation guardrails for retention, and a Step 11 verification block, but Step 11 is a check rather than an explicit validate→fix→retry feedback loop. | 4 / 5 |
Progressive Disclosure | No bundle files exist and the ~470-line SKILL.md inlines content that could live in separate references (API/deprecated mappings, Schema Best Practices, detailed column-selection guides); internal section headers provide structure but there is no one-level-deep reference navigation. | 3 / 5 |
