75%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 lean, opinionated conventions catalog that tells Claude exactly which checks to author, at what severity, and how to name and retire them, with concrete rules-of-thumb throughout. Its main weaknesses are mildly redundant prose in a few sections, vague per-engine severity specifics that sit awkwardly between concrete guidance and clean deferral, and no explicit multi-step workflow with checkpoints (though the task type doesn't demand them).
Suggestions
Tighten the intro paragraph and the freshness rationale ('the most common silent failure') so each point is made once — this would lift conciseness to fully lean.
For the severity-tiering section, either give one concrete config snippet per engine (e.g. a dbt `severity: warn` block and a SodaCL `warn:`/`fail:` example) or drop the per-engine specifics entirely and point straight to the engine skills, since the current half-specific description is the least actionable passage.
Consider moving the common-anti-patterns table and the engine-selection justifications into a references/ file (e.g. anti-patterns.md), keeping SKILL.md as a tighter overview — this would also give the skill a genuine progressive-disclosure layer.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Dense, table-driven reference with no explanations of concepts Claude already knows; only minor trimmable prose remains (the intro's 'those tell you the **how**... this tells you **which** checks' framing and phrases like 'the shop should treat distribution monitoring as a separate concern'). Not 5 because a few justification sentences restate their point twice. | 4 / 5 |
Actionability | Gives concrete, directly applicable guidance: a named starter set (`not_null`, `unique`, `relationships`, `accepted_values`), an explicit threshold rule ('The freshness threshold is **2× the expected cadence**... A daily pipeline gets `freshness < 2d`'), naming examples (`not_null_orders_email`, `missing_count(email) = 0`), and a promotion policy ('Land new checks at `warn` for two cycles, then promote'). Not 5 because the per-engine severity mechanics are vague ('suite-level metadata', 'the alert configuration syntax') with no concrete config example. | 4 / 5 |
Workflow Clarity | A clear authoring sequence is signaled explicitly ('Use this matrix to pick an engine **before authoring any checks**', 'start at the **column level** for the keys and required fields, then add **table-level** invariants') and the skill closes with an explicit check-lifecycle/retirement workflow. Not 5 because there are no validation-style checkpoints; not 3 because this is a design-reference skill rather than a destructive/batch-execution workflow, so the missing-feedback-loop cap does not apply. | 4 / 5 |
Progressive Disclosure | Single well-organized file with consistent section structure, and it correctly defers engine-specific syntax to the sibling skills ('Each engine's specifics are in its SKILL.md') instead of inlining it. Not 5 because at ~125 lines it exceeds the simple-skill threshold and content like the anti-patterns table and engine-comparison rows could arguably live in reference files; no bundle files exist to verify navigation against. | 4 / 5 |
