Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 28d ago · by lpm-firewall-aiThe postinstall hook mutates the OpenCode configuration, which merits a warning as first-party agent setup. The inspected runtime excerpts do not establish malicious behavior or a confirmed attack surface beyond that setup.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm runs the postinstall hook during installation.
Impact
The package adds its commands and skill to the user's OpenCode configuration.
Mechanism
The hook creates OpenCode command and skill directories and copies package files into them.
AI rationale
The postinstall hook mutates the OpenCode configuration, which merits a warning as first-party agent setup. The inspected runtime excerpts do not establish malicious behavior or a confirmed attack surface beyond that setup.
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
- package.json runs a postinstall hook that copies package commands and a skill into the user's OpenCode configuration.
- dist/server.js runs the Plannotator CLI when its plugin behavior is invoked; the excerpt shows a temporary readiness file, not credential collection or network transmission.
- dist/server.js loads its bundled runtime through a package-relative path.
Evidence against
- The install hook writes OpenCode-specific commands and a Plannotator skill, consistent with this package's OpenCode integration.
- The inspected source excerpts do not establish credential exfiltration, remote payload execution, or destructive behavior.
