supabase-database
Generates Supabase database migrations, writes RLS policies with auth.uid(), configures auth integration, and generates TypeScript types. Use when creating tables, writing migrations, configuring RLS, or implementing Supabase auth.

Discovery
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.
This is a strong skill description that clearly defines its Supabase-specific niche with concrete actions and explicit trigger guidance. It uses third person voice correctly, includes domain-specific keywords that users would naturally use, and has a well-formed 'Use when...' clause. The description is concise yet comprehensive.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: generates migrations, writes RLS policies with auth.uid(), configures auth integration, and generates TypeScript types. These are precise, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers both 'what' (generates migrations, writes RLS policies, configures auth, generates TypeScript types) and 'when' with an explicit 'Use when...' clause listing specific trigger scenarios. | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'Supabase', 'migrations', 'RLS policies', 'auth.uid()', 'TypeScript types', 'tables', 'auth'. These cover the main terms a developer working with Supabase would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive due to the Supabase-specific terminology (RLS policies, auth.uid(), Supabase auth). Unlikely to conflict with generic database or TypeScript skills given the clear Supabase niche. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-crafted skill that efficiently covers Supabase migration workflows with concrete, executable examples and clear validation checkpoints. It respects Claude's intelligence by avoiding explanations of basic concepts while providing specific, actionable guidance. The progressive disclosure to project-specific config and the explicit error recovery loop in the workflow are particularly strong.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. It avoids explaining what Supabase, migrations, or RLS are—concepts Claude already knows. Every section serves a clear purpose with no padding or unnecessary context. | 3 / 3 |
Actionability | Provides fully executable SQL for table creation, RLS policies, and verification queries. The migration example is copy-paste ready with realistic naming conventions, and the type generation command is concrete. | 3 / 3 |
Workflow Clarity | The 7-step sequential workflow is clearly numbered with explicit validation checkpoints after steps 3 and 5, including specific assertions (migration completes, RLS passes, tests pass) and a failure recovery loop (revert, adjust, re-run). Destructive operations are explicitly called out with mitigation steps. | 3 / 3 |
Progressive Disclosure | The skill serves as a concise overview and immediately references the project-specific config file for customization. Content is well-structured into logical sections (rules, example, verification) without being monolithic or requiring multi-level navigation. | 3 / 3 |
Total | 12 / 12 Passed |
