Graduation rationale

Checks committed plugin hook command values for clipboard-reading behavior that can extract local user data.

Deterministic signal basis

JsonSignals command-string analysis over ArtifactKind::CursorPluginHooks for clipboard read utilities such as `pbpaste`, `wl-paste`, `xclip -o`, `xsel --output`, or PowerShell `Get-Clipboard`.

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 hooks execute in developer environments and should not silently harvest clipboard data that may contain secrets or internal material.

What Triggers ​

SEC693 matches committed plugin hook command values that invoke clipboard-reading utilities such as pbpaste, wl-paste, xclip -o, xsel --output, or PowerShell Get-Clipboard.

False Positives ​

Shared plugin hooks should not depend on hidden clipboard reads. If a workflow needs pasted input, it should require an explicit user action instead.

Remediation ​

Remove clipboard reads from the committed plugin hook and require explicit input instead of harvesting local clipboard state.
