supabase-migration-deep-dive

Quick Review

The skill provides a clear high-level framework for Supabase migration using the strangler fig pattern, with good structural organization delegating details to reference files. However, the main SKILL.md lacks sufficient actionable detail for a CLI agent to execute migrations independently—steps are too abstract (e.g., 'Create abstraction layer' without specifics on what to create, how to structure it, or what code patterns to use). The description is clear about when to trigger the skill, but the core instructions need more concrete guidance: specific file structures, code templates, migration scripts, data validation steps, and decision trees. The novelty is moderate—while Supabase migrations are valuable, the pattern itself is well-documented and a capable CLI agent could follow official docs. The skill would benefit from more prescriptive implementation details, concrete code examples in the main file, and clearer sequencing of technical steps to truly add value beyond existing documentation.
