Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 28d ago · by lpm-firewall-aiThe install hook automatically adds first-party plan-review commands to OpenCode, an agent configuration change that warrants a warning. Inspected runtime code is consistent with the package’s review function and does not establish a concrete attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm postinstall
Impact
The commands become available in the user’s OpenCode environment; the inspected evidence does not establish broader control or malicious behavior.
Mechanism
The hook creates the commands directory and copies the package’s Markdown command files into it.
AI rationale
The install hook automatically adds first-party plan-review commands to OpenCode, an agent configuration change that warrants a warning. Inspected runtime code is consistent with the package’s review function and does not establish a concrete attack.
