Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 14d ago · by lpm-firewall-aiThe install-time copy into OpenCode’s configuration is a real extension lifecycle risk and warrants a warning. The inspected source supports package-owned setup, not a confirmed attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The package manager runs the postinstall hook for an installation under node_modules.
Impact
OpenCode may load the added files, and matching existing files may be overwritten; no separate attack behavior was established.
Mechanism
The hook copies command files and the skill into the OpenCode config directory.
AI rationale
The install-time copy into OpenCode’s configuration is a real extension lifecycle risk and warrants a warning. The inspected source supports package-owned setup, not a confirmed attack.
Evidence
package.jsonscripts/postinstall.cjs
Decision evidence
public snapshotAI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs scripts/postinstall.cjs during installation.
- When installed under node_modules, the hook copies package command files and a skill into the OpenCode config directory, where existing files can be overwritten.
Evidence against
- The hook copies only package-owned command files and one skill; the inspected code shows no network transfer or unrelated agent-setting change.
