Graduation rationale

Checks committed plugin hook command values for explicit environment or shell-state enumeration commands.

Deterministic signal basis

JsonSignals command-string analysis over ArtifactKind::CursorPluginHooks for explicit environment enumeration primitives such as `printenv`, `env` used as a dump, `export -p`, `declare -xp`, or `compgen -v`.

Why It Matters ​

Dumping environment variables from a committed plugin hook is high-risk because developer shells often contain tokens, API keys, cloud credentials, and session material.

What Triggers ​

SEC741 matches plugin hook commands that invoke explicit environment enumeration primitives such as printenv, env used as a dump, export -p, declare -xp, or compgen -v.

False Positives ​

Shared committed plugin hooks should not enumerate the developer environment. Legitimate diagnostics should be explicit, local-only, and initiated by the user.

Remediation ​

Remove environment dumping behavior from the committed plugin hook and require deliberate user-driven diagnostics outside shared automation.
