Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 28d ago · by lpm-firewall-aiThe install-time write to OpenCode's command directory is a real agent extension lifecycle risk, but the copied files expose package-aligned annotation and review actions. The inspected source does not establish a concrete attack, so this warrants a warning rather than a block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The package postinstall hook runs during installation.
Impact
The commands become available in the user's OpenCode environment.
Mechanism
The hook creates the OpenCode commands directory and copies the package's Markdown command files there.
AI rationale
The install-time write to OpenCode's command directory is a real agent extension lifecycle risk, but the copied files expose package-aligned annotation and review actions. The inspected source does not establish a concrete attack, so this warrants a warning rather than a block.
Evidence
package.jsoncommands/plannotator-annotate.mdcommands/plannotator-last.mdcommands/plannotator-review.md${XDG_CONFIG_HOME:-$HOME/.config}/opencode/commands/
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook copies package-supplied Markdown commands into OpenCode's user command directory.
- Those commands provide annotation and code-review entrypoints, consistent with the package's stated plugin purpose.
Evidence against
- The manifest defines postinstall behavior that modifies an AI-agent command directory during installation.
