Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 28d ago · by lpm-firewall-aiThe postinstall hook automatically installs package-owned OpenCode commands and a skill, which fits the warning category for first-party agent extension setup. The inspected server’s dynamic import is for its optional embedded review runtime; no separate concrete attack behavior was identified.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The package’s postinstall lifecycle hook runs during installation.
Impact
The package adds its own OpenCode commands and skill to the user configuration; no broader control-surface mutation was established.
Mechanism
It creates OpenCode command and skill directories and copies package files into them.
AI rationale
The postinstall hook automatically installs package-owned OpenCode commands and a skill, which fits the warning category for first-party agent extension setup. The inspected server’s dynamic import is for its optional embedded review runtime; no separate concrete attack behavior was identified.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook copies package-owned commands and a skill into the user’s OpenCode configuration directories.
- The server dynamically imports its optional embedded runtime when a plan review is invoked.
Evidence against
- The inspected install behavior is limited to OpenCode-specific command and skill setup; no unrelated recipient or destructive action was identified.
