Don’t paste secrets in chat

Store sensitive info in backend env vars or a secrets manager and access via functions.

Least privilege and environment isolation

Separate production/test/dev; grant roles/tokens on a need‑to‑use basis to avoid wide privileges.

Dependency and build security

Upgrade dependencies regularly, enable SCA/CI scanning; avoid bundling large secrets or certificates into the frontend.

API and data security

All public endpoints must enforce auth and rate limits; validate inputs and file uploads; protect PII and privacy data.

Pre‑publish checks

Run an automated checklist before publishing: secret leakage, debug flags, error logging, CORS policy, etc.
