Guide Supabase application work. Use for Supabase Auth, Postgres, RLS,.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Supabase Use this skill when working on Supabase tasks. ## Workflow - Inspect project config, migrations, generated types, RLS policies, auth flow, and environment variables before changes. - Treat service-role keys and database URLs as secrets; prefer local development and migration review before production. - Validate RLS, schema changes, and auth edge cases with focused tests or SQL checks. - For performance work, start with the query shape and `EXPLAIN` plan before adding indexes, denormalizing data, or changing client code. - Review indexes with workload context, including candidate, redundant, partial, composite, and foreign-key indexes; use Supabase advisor tooling where available. - Check RLS policy performance separately from correctness. Avoid policy predicates that force avoidable per-row work on hot paths. - Use `pg_stat_statements` or equivalent query statistics to identify slow, frequent, or high-variance statements before optimizing. - Inspect connection pooling, transaction scope, lock waits, long-running transactions, and migration ordering when performance or deploy safety is involved. ## Boundaries - Inspect the target repository before making changes. …

How to install
mdr add cruxexperts/localsetup/ls-supabase-app-development@sha256:c3d80084f718c662The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
