Guide for creating and using secrets in Fusebase Apps app backends. Use when: (1) An app backend needs API keys, passwords, or other sensitive config, (2) Creating secrets via the CLI, (3) Accessing secrets at runtime in backend code, (4) Deciding what should be a secret vs. a regular env var.

From the source SKILL.md

Secrets are encrypted key-value pairs stored in Fusebase and injected into the app backend at runtime as environment variables. Use them for sensitive config that must not be committed to source control (API keys, passwords, tokens, etc.).
