Quality

Content

53%Weight 40%Scale 1-5

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

The body is a concise, well-intentioned decision hub with a clear selective-reading map, checklist, and anti-patterns, but it is hollow in practice: every reference file it points to is missing from the bundle, no concrete selection criteria or examples are inlined to compensate, and the "When to Use" section is boilerplate filler.

Suggestions

Create the six advertised reference files (database-selection.md, orm-selection.md, schema-design.md, indexing.md, optimization.md, migrations.md) in a references/ directory, or remove the content-map table if the detail is not shipped.

Inlines some concrete decision guidance (e.g., a short database-selection criteria list or example schema snippet) so the skill is actionable even before references are loaded.

Delete the boilerplate "When to Use" sentence ("This skill is applicable to execute the workflow or actions described in the overview.") or replace it with a genuine trigger/usage description.

DimensionReasoningScore

Conciseness

The body is lean with no explanatory padding of known concepts; the checklist and anti-patterns are terse and directive. It is not 5 because the "When to Use" section is contentless boilerplate ("This skill is applicable to execute the workflow or actions described in the overview.") and the motivational tagline adds tokens without guidance.

4 / 5

Actionability

Some concrete guidance exists (the decision checklist's specific questions and anti-patterns like "Don't default to PostgreSQL for simple apps (SQLite may suffice)"), but there are no decision criteria, commands, or examples for actually choosing a database/ORM — the specifics are delegated to reference files that don't exist in the bundle. This matches 'some concrete guidance but incomplete; missing key details' rather than 4's 'concrete code or commands with minor gaps'.

3 / 5

Workflow Clarity

The pre-design checklist implies a reasonable sequence (ask preferences, choose database, consider environment, plan indexes, define relationships), but there are no validation checkpoints, and the rubric notes feedback loops matter for database operations. It is not 2 because the steps are reasonably defined rather than rough, and not 4 because verification steps are absent entirely.

3 / 5

Progressive Disclosure

The content-map table is well-formed in shape, but scored against the actual bundle none of the six advertised reference files (database-selection.md, orm-selection.md, schema-design.md, indexing.md, optimization.md, migrations.md) exist — there is no references/ directory at all. The body is effectively a hub pointing to nonexistent detail, which fails disclosure in practice and matches the 'minimal structure' anchor rather than the 'references present but not clearly signaled' anchor at 3.

Description

66%Weight 40%Scale 1-5

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 specific, appropriately concise description that names a distinct database-design niche with several concrete capability areas, but it completely lacks a 'when to use' trigger clause, which both caps completeness and weakens its invocation guidance.

Suggestions

Append an explicit trigger clause, e.g. 'Use when the user asks about choosing a database, designing a schema, defining indexes, picking an ORM, or working with serverless databases.'

Include common technology names users actually mention (PostgreSQL, SQLite, Prisma, Drizzle, migrations) to improve trigger term coverage and distinctiveness against generic backend skills.

DimensionReasoningScore

Specificity

The description lists several specific capability areas ("Schema design, indexing strategy, ORM selection, serverless databases"), which matches the 'several specific actions; minor gaps' anchor. It falls short of 5 because the areas are topic nouns rather than concrete actions and coverage has gaps (e.g., migrations, query optimization are absent).

4 / 5

Completeness

The 'what' is clearly stated (database design principles, schema design, indexing, ORM selection, serverless databases), but there is no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is not 2 because the 'what' is specific rather than vague, and not 4 because the 'when' is entirely absent rather than merely imprecise.

3 / 5

Trigger Term Quality

Natural phrases like "database design", "schema design", "indexing", and "ORM selection" are terms users would actually say, matching the 'good keyword coverage; a few natural terms missing' anchor. It is not 5 because there are no synonyms, file extensions, or named technologies (PostgreSQL, Drizzle, Prisma, SQL, migrations) that users commonly mention.

4 / 5

Distinctiveness Conflict Risk

The description carves out a clear database-design niche, matching 'mostly distinct; minor overlap risk with closely related skills'. It is not 5 because without explicit trigger phrases it could overlap with generic SQL, backend-setup, or migration skills.
