Agent Skills: spice-secrets

Configure secret stores in Spice — environment variables, Kubernetes, AWS Secrets Manager, Azure Key Vault, HashiCorp Vault, and OS keyring. Use this skill whenever the user needs to manage credentials, API keys, passwords, or tokens in Spice, reference secrets in spicepod.yaml params with ${ store:KEY } syntax, set up .env files, configure secret store precedence, or understand how the `secrets:` section works. Also use when the user asks how to pass database passwords or API keys securely to Spice datasets or models.
