Graduation rationale

Checks committed plugin hook command values for explicit secret-bearing network exfil payloads.

Deterministic signal basis

JsonSignals command-string analysis over ArtifactKind::CursorPluginHooks for secret markers combined with network-capable command context.

Canonical note

Structural stable rule positioned as an explicit threat-review control: high-signal malicious, credential-bearing, or spyware-like behavior that stays opt-in rather than shaping the quiet default.

Why It Matters ​

Committed plugin hook commands run as part of the plugin lifecycle, so any secret-bearing network send becomes part of the default execution path for downstream users.

What Triggers ​

SEC680 matches plugin hook commands that combine secret markers with a network-capable command path.

False Positives ​

If a plugin needs authenticated access, keep secret handling inside the plugin logic or server process rather than in a raw shared hook command.

Remediation ​

Remove the secret-bearing network send from the committed plugin hook and keep secret access local to the trusted component.
