⚠Review·Scanned 2/18/2026

This skill documents deploying Python apps to Google App Engine, covering app.yaml, Cloud SQL sockets, Cloud Storage, Secret Manager, and common deploy commands. It instructs running shell commands (gcloud, docker, cloud-sql-proxy), using secrets (Secret Manager, env vars like DB_PASSWORD), and copying rules to .claude/rules/google-app-engine.md.
