Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package has a real scoped AI-agent lifecycle mutation, warranting a warning under the install-control-surface policy. Source inspection did not establish malicious behavior.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm postinstall; then OpenCode plugin loading or explicit Plannotator commands
Impact
Modifies an AI-agent command surface but no concrete malicious or exfiltration chain was found.
Mechanism
Same-platform command shim plus first-party agent-extension hooks
AI rationale
The package has a real scoped AI-agent lifecycle mutation, warranting a warning under the install-control-surface policy. Source inspection did not establish malicious behavior.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- package.json postinstall copies commands into OpenCode config
- dist/index.js installs plan-review hooks and rewrites agent prompts
- dist/server.js dynamically imports bundled embedded.js at runtime
Evidence against
- postinstall copies only this package's three Markdown command descriptors
- no install-time network, code execution, or credential harvesting found
- spawn uses shell:false and invokes the configured plannotator CLI only after plugin actions
- embedded server is a local review UI; URL fetching is tied to explicit annotate commands
