+- **Credential / secret extraction (check ALL shipped code, not just hooks).**
+  Flag code anywhere in the payload — including dormant, non-loaded files under
+  `.claude/`, `scripts/`, etc. — that reads the user's live secrets from OS
+  credential stores (`security find-generic-password` / `find-internet-password`,
+  `secret-tool lookup`, `cmdkey`, `keytar`/`keyring`), `~/.aws/credentials`,
+  private SSH keys, `~/.claude/.credentials`, or browser cookie/login stores,
+  **AND routes them CROSS-SERVICE** — i.e. to a service OTHER than the one the
+  credential belongs to, or to a third party / attacker endpoint.
+  The red flag is the cross-service hop: e.g. reading Anthropic's
+  `ANTHROPIC_AUTH_TOKEN` (an account/OAuth token) and sending it to a
+  **non-Anthropic** endpoint — the vercel-style misuse. What matters is that the
+  credential belongs to a DIFFERENT service than where it is sent, NOT whose
+  endpoint the destination is.
+  Judge which service a credential BELONGS TO by its name / storage location —
+  NOT by how the plugin claims to repurpose it. A keychain entry or env var
+  named `ANTHROPIC_AUTH_TOKEN` / `ANTHROPIC_*` belongs to **Anthropic**;
+  `~/.railway/config.json` belongs to Railway; `~/.aws/credentials` to AWS; a
+  `gcloud` token to Google. So a plugin reading `ANTHROPIC_AUTH_TOKEN` and
+  sending it to a non-Anthropic endpoint (e.g. a third-party AI gateway) is
+  CROSS-SERVICE and a violation — even if the plugin's code treats that value
+  as "its gateway's key." The user may have stored their real Anthropic account
+  token there; reading an Anthropic-named credential and routing it off to
+  another vendor is the trust-boundary breach regardless of the plugin's intent.
+  Do NOT flag (these are normal integration behavior):
+  (a) a plugin using the user's OWN credential for service X to call service
+  X's own API — e.g. a Railway plugin reading the Railway CLI token to call
+  Railway, an AWS plugin reading `~/.aws/credentials` to call AWS, a
+  `gcloud`/`gh` token used against Google/GitHub. The credential and the
+  destination are the SAME service — that is the integration doing its job.
+  (b) instructing the user to SET their own key (`export SOME_TOKEN=...`).
+  Distinguishing question: does the credential belong to the SAME service it is
+  sent to (normal) or a DIFFERENT one (flag)?
 
 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.
