65%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 overview skill with clean progressive disclosure (one real reference file, clearly linked) and concrete verification commands, but it carries redundancy (the 'When to use' section duplicates the description verbatim, plus an irrelevant repo-maintenance line) and lacks an explicit error-recovery loop in its workflow, which the rubric caps at 3 for database-operation skills.
Suggestions
Delete the 'When to use this skill' section — it repeats the frontmatter description's five trigger phrases verbatim — and remove the 'After editing this repository's XML sources, regenerate skills and verify the build' line, which is repo-maintenance boilerplate rather than skill guidance.
Add an explicit feedback loop to the workflow, e.g. after step 4: 'If `mvn verify` or `explain()` review fails, fix the issue and re-run before reporting results; only promote changes when verification passes.'
Move the 'What is covered' bullets into the reference file or trim them to a one-line scope statement, since the frontmatter description already carries this inventory at load time.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly directive with no conceptual padding (no explaining what MongoDB or an index is), but it can be tightened: the entire "When to use this skill" section repeats the frontmatter trigger list verbatim (already visible at load time), the "What is covered" bullets restate the description's topic inventory, and the line "After editing this repository's XML sources, regenerate skills and verify the build" is repo-maintenance boilerplate irrelevant to skill consumers. This matches anchor 3 (mostly efficient, some unnecessary content that could be trimmed) rather than anchor 4, where only minor instances remain. | 3 / 5 |
Actionability | Concrete, executable anchors are present: exact commands ("Run `./mvnw compile` or `mvn compile`", "Run `./mvnw clean verify`"), specific inspection criteria ("Review `explain()` plans, scanned/returned ratios, sort coverage, and index selectivity"), a named reference file to read, and explicit behavioral rules (never concatenate untrusted input into query documents or `$where`). Minor gaps: the body itself contains no example query/index/aggregation snippets — those are delegated to the reference — and a few constraints read as policy statements ("Prefer explicit document contracts, bounded arrays, stable identifiers") without concrete patterns. This lands on anchor 4 rather than 5. | 4 / 5 |
Workflow Clarity | The four-step workflow (read reference and assess context → identify workload constraints → apply changes → run verification and report) is clearly sequenced with named verification commands, but there is no explicit validate→fix→retry feedback loop (no 'if compilation or verification fails, fix and re-run') — the rubric's scoring notes call feedback loops essential for database operations and cap workflow clarity at 3 without them. Anchor 3 (steps listed, checkpoints implicit/missing) fits; anchor 4 would require most recovery checkpoints to be explicit. | 3 / 5 |
Progressive Disclosure | The body is a lean overview: coverage summary, constraints, workflow, and a clearly signaled one-level-deep reference — "For detailed guidance, examples, and constraints, see [references/705-technologies-nosql-mongodb.md](references/705-technologies-nosql-mongodb.md)" — and the referenced file exists in the bundle with no further nesting. This matches anchor 5 (clear overview, well-signaled single-level references, easy navigation). | 5 / 5 |
