87%Weight 40%Scale 1-3Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, actionable skill body that avoids concept-padding and supplies executable commands plus a useful inline schema reference. The main gap is the lack of an explicit write-then-verify feedback loop for destructive database operations, which caps workflow clarity.
Suggestions
Add an explicit validation checkpoint to the Workflow for write operations, e.g. after 'write', verify the affected row count matches expectation and re-query to confirm the change before reporting success, with a rollback/fix-and-retry path if it does not match.
Consolidate the overlapping 'Built-in Safety' and 'Safety Rules' sections to remove the duplicated 'query --write' compatibility note and tighten the read-only vs write distinction into one place.
For destructive statements (DELETE/DROP/TRUNCATE), make the backup step part of the numbered workflow rather than only a safety rule, so the validate->backup->write->verify loop is unambiguous.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence — no padding about what SQL or a database is — and the bulk of tokens are high-value schema reference (Core Tables columns, Common Queries, SQL Dialect Notes) that Claude cannot know. There is minor overlap between 'Built-in Safety' and 'Safety Rules' but no concept-explanation bloat. | 3 / 3 |
Actionability | Commands section provides fully executable invocations (e.g. 'python scripts/mp-db.py tables', 'schema downloadhistory', 'query ...', 'write ...') and Common Queries supplies copy-paste-ready SQL, matching the 'fully executable; copy-paste ready' anchor. | 3 / 3 |
Workflow Clarity | The Workflow lists a clear sequence (tables -> schema -> query -> write) with safety guidance, but lacks an explicit validate-then-fix-then-retry feedback loop; per the rubric's scoring notes, database operations are capped at 2 when feedback loops are missing. | 2 / 3 |
Progressive Disclosure | Content is organized into well-labeled sections and references the single bundled script 'scripts/mp-db.py' one level deep (verified to exist) with no nested references, providing easy navigation. | 3 / 3 |
