Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe install-time mutation merits a warning because it affects an OpenCode control surface without an explicit command, but it is limited to this package's own command definitions. Source inspection found no concrete malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall; later OpenCode plugin loading
Impact
Modifies an AI-agent command surface for this package's integration.
Mechanism
OpenCode command setup and plan-review extension registration
AI rationale

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- postinstall copies bundled command definitions into the user's OpenCode commands directory.
- Runtime plugin injects a submit_plan tool and modifies planning prompts when loaded by OpenCode.
Evidence against
- The install hook only creates/copies local Markdown command files; it has no network or executable payload.
- Child-process use is runtime-only, invokes the configured plannotator CLI with shell disabled.
- No credential harvesting, remote code download, or destructive behavior was confirmed.
