PostgreSQL users need a reliable way to inspect schemas, run safe diagnostics, and query or validate data without relying on untrusted community tooling.
Example use case: When a user asks why a metric changed, you can query the relevant tables, inspect the schema for constraints or new columns, and run EXPLAIN on any suspect query to diagnose performance regressions.
Ask the skill to connect using your project-scoped DATABASE_URL and run the specific read-only query or schema inspection you need.

To run safe read-only PostgreSQL queries using psql, this skill enforces read-only constraints to inspect schemas and query data without risking unintended writes to your database.
Yes, you can inspect Supabase database schemas with psql. This skill supports listing tables, functions, roles, databases, and extensions across Supabase and self-hosted Postgres variants.
The best way to diagnose PostgreSQL performance regressions is using EXPLAIN-based performance diagnosis. This skill runs EXPLAIN on suspect queries to identify bottlenecks and schema constraints.
To execute controlled database migrations safely in PostgreSQL, this skill wraps risky writes in transactions and follows EXPLAIN-first workflows to validate changes before committing them.
Yes, you need a valid PostgreSQL connection string sourced from Infisical or operator-local secrets. This skill requires this project-scoped DATABASE_URL to establish a trusted psql connection.
You should not use psql for database querying if you lack a valid PostgreSQL connection string from Infisical or operator-local secrets, as this skill depends on trusted access for safe operations.
