AI Security Review
scanned 28d ago · by lpm-firewall-aiThe postinstall hook mutates OpenCode configuration by installing package-owned commands, which warrants a warning under the extension lifecycle policy. The reviewed runtime excerpt does not show an unrelated dynamic import target or establish a concrete attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Installing the package runs its postinstall hook.
Impact
The package’s commands become available in the user’s OpenCode environment.
Mechanism
The hook creates the OpenCode commands directory and copies command markdown files there.
AI rationale
The postinstall hook mutates OpenCode configuration by installing package-owned commands, which warrants a warning under the extension lifecycle policy. The reviewed runtime excerpt does not show an unrelated dynamic import target or establish a concrete attack.
Evidence
package.json
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook copies package command files into the user’s OpenCode commands directory.
- The server dynamically imports only its sibling embedded runtime when that file exists.
Evidence against
- The inspected runtime import is tied to the package’s embedded file; no unrelated dynamic target is shown in the cited code.
