Use when a workload (agent, sandbox, container, CI job) must call an authenticated upstream (LLM/provider/cloud API) but should not hold the credential itself. Keep the secret in a proxy that injects it, so a compromised workload cannot exfiltrate the key.

From the source SKILL.md

Keep upstream credentials OUT of the workload. Put a small reverse proxy between the workload and the upstream API; the proxy holds the secret and injects it. The workload authenticates to the proxy (cheap, internal) and never sees the upstream key.
