88%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 dense, highly actionable skill body with genuinely valuable gotchas (permission-rule propagation delay, result._id shape, get()-on-missing-doc HTTP 500 behavior) and strong validation/retry feedback loops. The main costs are duplicated passages across "Common mistakes" and "Working rules", and quick-routing targets that don't resolve to real files in this environment.
Suggestions
Deduplicate the CMS CUSTOM-rule pattern and the result._id gotcha: keep one-line pointers in 'Common mistakes' and put the full pattern once in security-rules.md (which is already routed to).
Ensure the seven quick-routing companion files (crud-operations.md, complex-queries.md, pagination.md, aggregation.md, realtime.md, geolocation.md, security-rules.md) ship with the skill, or note — as the body already does for sibling skills — how to obtain them when missing.
The 'Best practices' list (naming conventions, indexes, field selection) largely restates guidance already given in 'Working rules' and 'Quick examples'; consider merging it into one section.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body assumes Claude's competence (no concept explanations, no library comparisons) and every section carries operational value. Not 5 because content is duplicated: the CMS CUSTOM-rule pattern appears in full in both "Common mistakes" and Working rule 3, and the result._id gotcha is stated in "Common mistakes", Working rule 5, and the Quick examples; not 3 because these are trimmable repetitions rather than padded explanation. | 4 / 5 |
Actionability | All examples are executable, copy-paste-ready JavaScript: canonical init, where().get(), add() with "const articleId = result._id", orderBy/skip/limit pagination, field selection, and try/catch error handling. Non-code guidance is equally concrete (e.g. the exact CUSTOM rule expression and the get() round-trip verification). This matches the anchor-5 'fully executable, covers common cases' example; 4 would require gaps in the covered cases, and the CRUD/query/pagination/error set is complete for the skill's scope. | 5 / 5 |
Workflow Clarity | The sequence is clear: Activation Contract (use-first / read-before / do-not-use) → minimal checklist → sequenced working rules, and the database-operation feedback loops the rubric demands are all explicit: "wait a few minutes and retry the same write before assuming the rule is wrong", "verify the rule is live by reading result.code / result.message on every write and by doing a get() round-trip on the just-written _id", and "If the task fails with permission issues, inspect the rule model rather than assuming the query syntax is wrong." Not 4 because validation checkpoints are present and explicit, not merely implied. | 5 / 5 |
Progressive Disclosure | The "Quick routing" section cleanly maps each operation to a one-level-deep companion file (CRUD -> ./crud-operations.md, Security rules -> ./security-rules.md, etc.), which is exemplary signaling. Not 5 because those companion files (crud-operations.md, complex-queries.md, pagination.md, aggregation.md, realtime.md, geolocation.md, security-rules.md) are not present in this bundle — the routing points at files a reader cannot open here — and the deep CMS rule detail duplicated in Working rule 3 arguably belongs in security-rules.md. Not 3 because the overview/reference split itself is well organized and easy to navigate. | 4 / 5 |
