Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a first-party OpenCode extension with an install-time command shim and runtime agent-workflow influence, warranting a warning under the lifecycle policy. Source inspection does not establish malicious intent or a blocking attack chain.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm postinstall; later OpenCode plugin loading and submit_plan use
Impact
Adds OpenCode commands and can influence the host's planning workflow.
Mechanism
first-party OpenCode command installation and plugin prompt/tool integration
AI rationale
This is a first-party OpenCode extension with an install-time command shim and runtime agent-workflow influence, warranting a warning under the lifecycle policy. Source inspection does not establish malicious intent or a blocking attack chain.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- package.json postinstall copies bundled command files into the user's OpenCode command directory.
- dist/server.js registers a submit_plan tool and rewrites OpenCode planning prompts/tool descriptions at runtime.
- dist/server.js dynamically imports bundled dist/embedded.js for the embedded plugin runtime.
Evidence against
- The postinstall command only performs mkdir/cp; it has no network, credential, or payload-execution step.
- CLI spawning in dist/server.js occurs only when a user/agent invokes plan review and uses shell:false.
- Network fetching in dist/embedded.js is for user-supplied URL annotation/review; no install-time exfiltration was found.
- No eval/vm execution, secret harvesting, destructive filesystem behavior, or broad agent-config overwrite was found.
