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 highly actionable, well-structured skill body with excellent executable examples and real, well-signaled reference files. Its main cost is redundancy: the safe-query material appears twice (Workflow 4a and Security Considerations) and partially duplicates input-validation.md, inflating token spend for a skill loaded on every DSQL task.
Suggestions
Consolidate the five "Rubric-Critical" scenarios in Workflow 4a into input-validation.md and keep only the validator selection table plus one representative scenario inline, removing the near-verbatim overlap with Security Considerations items 6–8.
Fix Quick Start §2: it currently wraps prose instructions ("Use psql-connect.sh... Always include tenant_id...") in a plain code block — render these as bullet points or replace with an actual executable command.
State the per-workflow validation checkpoints inline (e.g., the batch-populate row-count verification in Workflow 2) rather than only by reference to workflow-patterns.md and ddl-migrations/*.md, so the validate→fix→retry loop is visible without loading the reference file.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is mostly efficient — the limits table, connector package names, and safe_query patterns are genuinely non-obvious DSQL knowledge — but Workflow 4a (~100 lines, five "Rubric-Critical" scenarios) substantially duplicates Security Considerations items 6–8, the validator table is explicitly stated to "mirror" input-validation.md, and Quick Start §2 wraps prose instructions in a code block. This lands on "could be tightened" rather than the minor-trim level 4 or the severely padded level 2. | 3 / 5 |
Actionability | Guidance is fully executable throughout: copy-paste bash invocations ("./scripts/psql-connect.sh --cluster <cluster-id> --command \"SELECT ...\""), complete Python examples with required imports, MCP JSON payloads with poll-readiness instructions, and a limits table with concrete verify queries. This matches the copy-paste-ready level-5 anchor. | 5 / 5 |
Workflow Clarity | Workflows 0–8 are clearly sequenced, with user-confirmation gates on the destructive Table Recreation workflow (Workflow 6), verify steps in the migration sequence ("add-column → batch-populate → verify → index"), and an explicit ask-before-proceeding checkpoint in Workflow 0, so the destructive/batch validation cap is satisfied. It falls short of level 5 because most detailed validation checkpoints are delegated to reference files rather than stated inline as validate→fix→retry loops. | 4 / 5 |
Progressive Disclosure | The Reference Files section signals every file with When/Contains cues, all referenced paths (references/*, scripts/*, platforms/*, query-plan/*) verified to exist as real one-level-deep files, and navigation is easy. However, the 555-line body inlines material that belongs in references — the full five-scenario safe-query treatment and the validator table that duplicates input-validation.md — keeping it below the "content appropriately split" level-5 anchor. | 4 / 5 |
