Quality

Content

80%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.

A dense, executable reference for Supabase database operations with good progressive disclosure to real reference files. Its main weakness is the absence of validation/verification guidance around destructive and RLS operations.

Suggestions

Add a verification checkpoint for destructive operations, e.g. select/count matching rows before running UPDATE or DELETE, or wrap destructive examples with a 'verify affected rows first' note.

Include a short validate-then-apply feedback loop for RLS policy changes (e.g. test the policy with auth.uid() impersonation before relying on it).

Trim the Quick Reference table or the duplicated Basic Queries section to reduce redundancy between the overview and the detailed examples.

Dimension	Reasoning	Score
Conciseness	Mostly lean code examples with terse comments and no concept over-explanation, but the Quick Reference table repeats patterns expanded in later sections, leaving minor redundancy to trim.	4 / 5
Actionability	Fully executable, copy-paste-ready JavaScript, SQL, TypeScript, and bash snippets covering the common cases (queries, filters, joins, RLS policies, RPC, type generation).	5 / 5
Workflow Clarity	Content is a reference catalog rather than a sequenced workflow, and destructive operations (delete, update, RLS changes) appear with no validation or verification checkpoints; the destructive-operations cap holds this at 3.	3 / 5
Progressive Disclosure	Clear overview with three well-signaled, one-level-deep references (rls-policies.md, query-operators.md, postgres-functions.md) that are real files, keeping the body focused and navigable.	5 / 5

Description

87%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 strong, well-structured description that clearly states capabilities and provides explicit 'Use when' trigger guidance scoped to Supabase database work. Minor gains possible by adding spelled-out synonyms ('row level security', 'policies').

Dimension	Reasoning	Score
Specificity	Lists several concrete actions ('queries, CRUD operations, RLS policies, and PostgreSQL functions') with minor gaps; 'CRUD operations' and 'managing data' are somewhat generic, keeping it below the comprehensive level 5 anchor.	4 / 5
Completeness	Explicitly answers both 'what' (Supabase database operations including queries, CRUD, RLS, PostgreSQL functions) and 'when' ('Use when querying tables, managing data, implementing RLS, or writing database functions') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Includes natural trigger phrases ('querying tables', 'implementing RLS', 'database functions') that users would plausibly say, but misses some synonyms like the spelled-out 'row level security' and 'policies'.	4 / 5
Distinctiveness Conflict Risk	Scoped to Supabase database operations with distinct triggers (RLS, database functions); minimal risk of firing for unrelated skills.	5 / 5
	Total	18 / 20 Passed
