Database Function Lint Manager

Lint PostgreSQL functions across environments (local, staging, production), analyze function usage in the codebase, and generate actionable reports for fixing or dropping broken functions.

When to Use This Skill

DO use this skill when:

• Running supabase db lint and need to analyze/categorize results
• Detecting broken functions referencing non-existent columns/tables
• Analyzing which database functions are actually used in the codebase
• Generating cleanup recommendations for unused legacy functions
• Pre-deployment database validation
• Investigating database errors related to function calls

DO NOT use this skill when:

• Creating new database migrations (use database-migration-manager)
• Writing RLS policies (use rls-policy-generator)
• Fixing a single known function (just create the migration directly)
