SkillSpector looks for patterns such as shell commands, credential access, network calls or unpinned dependencies. An observation is something worth reading in the files before you install, not a confirmed vulnerability. Components that run code locally, like hooks, MCP servers and security tooling, naturally show more of them.

Patterns
Prisma with Neon Connection
Configure Prisma for Neon with connection pooling.
Use two connection strings:
- DATABASE_URL: Pooled connection for Prisma Client
- DIRECT_URL: Direct connection for Prisma Migrate
The pooled connection uses PgBouncer for up to 10K connections. Direct connection required for migrations (DDL operations).
Drizzle with Neon Serverless Driver
Use Drizzle ORM with Neon's serverless HTTP driver for edge/serverless environments.
Two driver options:
- neon-http: Single queries over HTTP (fastest for one-off queries)
- neon-serverless: WebSocket for transactions and sessions
Connection Pooling with PgBouncer
Neon provides built-in connection pooling via PgBouncer.
Key limits:
- Up to 10,000 concurrent connections to pooler
- Connections still consume underlying Postgres connections
- 7 connections reserved for Neon superuser
Use pooled endpoint for application, direct for migrations.
