supabase-skill vs planetscale-skills
Pick supabase-skill if you are on Postgres and want the agent to write row-level-security-correct queries, auth, and realtime by default. Pick planetscale-skills if you are on MySQL and want schema changes to behave like Git — branch, deploy-request, merge — without downtime at scale.
Pick supabase-skill
Your stack is Postgres (or Supabase), and RLS policies, auth flows, edge functions, and realtime are where you want the agent to stop making mistakes.
Pick planetscale-skills
Your stack is MySQL at scale, and you want branch-based, zero-downtime schema migrations with a deploy-request workflow.

Verdict
The bottom line
The choice follows your database, not the skill. If you already run Postgres or Supabase, supabase-skill removes the most common footguns — views bypassing RLS, updates silently returning zero rows — and knows auth and realtime. If you run MySQL on PlanetScale, planetscale-skills makes migrations reviewable and safe with the branch-and-deploy-request flow. Neither replaces the other; pick the one that matches the engine you are committed to.
FAQ
Common questions
Should I use the Supabase or PlanetScale skill?
Match your database. supabase-skill is for Postgres/Supabase and is strongest on row-level security, auth, and realtime. planetscale-skills is for MySQL on PlanetScale and is strongest on Git-style schema branching and zero-downtime migrations. Both are official, vendor-published, verified skills.
Is Supabase or PlanetScale better for schema migrations?
It depends on the model you want. planetscale-skills brings a branch / deploy-request / merge workflow that makes schema changes reviewable and non-blocking on MySQL. supabase-skill handles standard Postgres migrations and, crucially, keeps them row-level-security-aware. If Git-like migration branching is the priority, PlanetScale; if RLS-correctness is, Supabase.
