Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe postinstall hook automatically installs this package’s own OpenCode commands and skill into the user’s configuration, which warrants a warning under the agent-extension lifecycle rule. The reviewed credential bridge targets localhost, and I found no evidence that the install hook sends data externally.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
The package manager runs the postinstall hook when installing the package.
Impact
The package adds its own commands and skill to the user’s agent configuration without a separate user command.
Mechanism
The hook copies command markdown files and skills/plannotator/SKILL.md into the OpenCode config directory.
AI rationale
The postinstall hook automatically installs this package’s own OpenCode commands and skill into the user’s configuration, which warrants a warning under the agent-extension lifecycle rule. The reviewed credential bridge targets localhost, and I found no evidence that the install hook sends data externally.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The postinstall hook runs scripts/postinstall.cjs during installation.
- The script copies the package’s command stubs and Plannotator skill into the user’s OpenCode config directory.
Evidence against
- The install script performs local filesystem copies; no network request or unrelated data collection appears in it.
- The flagged bearer-token bridge sends requests to 127.0.0.1 at a port read from the local Inbox registry.
