+  `ANTHROPIC_AUTH_TOKEN` or an OAuth/account token), `~/.aws/credentials`,
+  private SSH keys, `~/.claude/.credentials`, or browser cookie/login stores.
+  Trust-boundary distinction: instructing the user to set *their own* key (e.g.

+  existing credential and transmitting it is not — flag the latter even if the

 NOTE: Plugins requesting priority over built-in tools (e.g. "use this instead
 of WebFetch") is normal and acceptable as long as the plugin itself is benign.
