 Copilot's Function and code-execution tools receive a saved secret only when their code explicitly contains a valid `{{KEY}}` reference. Direct `environmentVariables.KEY` access, shell `$KEY`, dynamic names, literals, and configured-but-unused secrets do not mount a value. Code execution requires workspace write access, and the caller must be allowed to **use** the secret — the same set a workflow resolves for them: your own Personal secrets, and Workspace secrets you hold an active grant on as a Credential Member or Credential Admin, which a workspace admin holds on every key. A secret you hold no grant on does not mount, and neither does one whose grant is revoked or still pending.
