database-design

Designs database schemas, indexing strategies, query optimization, and migration patterns for SQL and NoSQL databases. Use when designing tables, optimizing queries, fixing N+1 problems, planning migrations, or when asked about database performance, normalization, ORMs, or data modeling.

Quality

Content

80%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is dense, lean, and highly actionable with strong WRONG/CORRECT code contrasts across SQL and NoSQL. It loses points on workflow clarity (no explicit validation feedback loops for destructive/batch operations) and progressive disclosure (entirely inline with no reference files).

Suggestions

Add explicit validation checkpoints to the migration and bulk-operation workflows (e.g., 'run ANALYZE and verify row counts; if mismatch, re-run backfill batch') to enable a validate-fix-retry loop.

Split large independent domains (NoSQL patterns, migration guide, ORM best practices) into separate reference files under references/ and link to them one level deep from SKILL.md.

Add a rollback/verification step to the zero-downtime migration example so the sequence explicitly confirms no reads of the old column before the drop.

DimensionReasoningScore

Conciseness

Almost entirely executable code with tight, purposeful comments and no explanation of concepts Claude already knows; length reflects genuinely distinct domains rather than padding, matching the lean score-3 anchor.

3 / 3

Actionability

Code is complete and copy-paste ready — real CREATE TABLE/INDEX CONCURRENTLY statements, working SQLAlchemy/Prisma snippets, and cursor-pagination SQL with explicit WRONG/CORRECT contrasts, matching the score-3 anchor.

3 / 3

Workflow Clarity

Provides an 8-step progress checklist and a sequenced zero-downtime migration example, but the migration and bulk-operation workflows (destructive/batch) lack explicit validate-then-fix-then-retry checkpoints, which per the rubric caps clarity at 2.

2 / 3

Progressive Disclosure

No bundle files exist; the skill is a single ~384-line monolithic file with content (NoSQL patterns, migration guide, ORM practices) that could be split into one-level-deep references, matching the 'content that should be separate is inline' score-2 anchor.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: third-person voice, concrete multi-action capability list, and an explicit 'Use when' clause with a rich set of natural trigger terms. It clearly answers both what the skill does and when to invoke it.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions across distinct sub-domains: 'Designs database schemas, indexing strategies, query optimization, and migration patterns', matching the score-3 anchor rather than the partial coverage of score 2.

3 / 3

Completeness

Explicitly answers both what (first sentence) and when via a clear 'Use when...' clause with multiple triggers, matching the score-3 anchor exactly.

3 / 3

Trigger Term Quality

Excellent coverage of natural user terms including 'designing tables, optimizing queries, fixing N+1 problems, planning migrations... normalization, ORMs, or data modeling', exceeding the 'some relevant keywords' bar of score 2.

3 / 3

Distinctiveness Conflict Risk

Clear database-design niche with distinct triggers unlikely to fire for unrelated skills; not the generic overlap of score 2.
