Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 7d ago · by lpm-firewall-aiThe postinstall hook modifies OpenCode configuration by installing this package's commands and skill automatically, which is an agent extension lifecycle risk. The reviewed behavior is purpose-related; no unrelated credential transfer or external install-time contact was identified.
Static reason
One or more suspicious static signals were detected.
Trigger
A package manager runs postinstall for an installed copy under node_modules.
Impact
OpenCode gains package-provided commands and skill instructions automatically after installation.
Mechanism
The script copies command markdown files and the Plannotator skill into the OpenCode config directory; files with matching names may be overwritten.
AI rationale
The postinstall hook modifies OpenCode configuration by installing this package's commands and skill automatically, which is an agent extension lifecycle risk. The reviewed behavior is purpose-related; no unrelated credential transfer or external install-time contact was identified.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- package.json runs scripts/postinstall.cjs from its postinstall lifecycle hook.
- The postinstall copies assets by default when the package path is under node_modules.
- It copies the package's command stubs and Plannotator skill into the user's OpenCode configuration, including paths under commands and skills/plannotator.
Evidence against
- The copied assets are commands and a skill for the package's stated OpenCode plan and code review purpose.
- The inspected Inbox health check contacts only 127.0.0.1.
