Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 18d ago · by lpm-firewall-aiThe manifest activates a postinstall script that copies package-owned OpenCode commands and a skill into user configuration, with same-name replacement possible. This is first-party agent extension setup, so the appropriate verdict is a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package with a manager that runs its postinstall hook, when the package is under node_modules or the copy is explicitly forced.
Impact
OpenCode command or skill instructions may be changed by the installed package assets.
Mechanism
The hook copies package command files and the Plannotator skill into the OpenCode configuration directory, replacing same-named files if present.

Evidence

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs scripts/postinstall.cjs from its postinstall hook.
- The hook runs automatically when invoked as the main script; copying is enabled for installed paths under node_modules and skipped for workspace paths unless explicitly forced.
- The script copies package command files and its Plannotator skill into the OpenCode configuration directory, where copies can replace same-named files.
- dist/index.js exports the OpenCode plugin that uses this package's integration assets.
Evidence against
- The install-time writes are limited to this package's own command and skill assets; no broader agent configuration change or malicious behavior was identified.
