Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is not malware, but its lifecycle hook and host-agent control-surface integration warrant a warning under the firewall policy.
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 user-initiated review/annotation
Impact
Changes OpenCode command/plugin behavior; interactive use can start local child processes.
Mechanism
First-party OpenCode extension setup and guarded local agent-terminal capability
AI rationale
This is not malware, but its lifecycle hook and host-agent control-surface integration warrant a warning under the firewall policy.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json postinstall copies package command files into ~/.config/opencode/commands.
- dist/server.js registers a submit_plan tool and rewrites OpenCode plan prompts/tools.
- dist/embedded.js can spawn an interactive agent-terminal sidecar after review UI activation.
Evidence against
- Postinstall copies only three package-owned Markdown command descriptors.
- Spawn calls use shell:false or argument arrays; no shell injection path found.
- No install-time network, credential harvesting, payload download, or exfiltration found.
- External fetches in dist/embedded.js are for user-selected URL annotation; Jina auth uses only JINA_API_KEY.
