Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 28d ago · by lpm-firewall-aiThe package’s postinstall hook automatically adds its own commands and skill to OpenCode configuration. This guarded first-party extension setup warrants a warning, but the inspected source does not establish a concrete malicious attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Installing the package with lifecycle scripts enabled.
Impact
Adds package-owned commands and a skill to OpenCode configuration; this is a guarded first-party extension setup risk.
Mechanism
The hook creates OpenCode command and Plannotator skill directories, then copies package files into them.
AI rationale
The package’s postinstall hook automatically adds its own commands and skill to OpenCode configuration. This guarded first-party extension setup warrants a warning, but the inspected source does not establish a concrete malicious attack.
