Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has a real automatic OpenCode control-surface mutation, so it warrants a warning under the lifecycle policy. Source inspection found no self-dependency chain, stealth download in postinstall, credential harvesting, or concrete malicious payload.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm postinstall during package installation, followed by use of an installed OpenCode command or skill.
Impact
An installer changes agent behavior without an explicit setup command, but the reviewed hook copies only package-owned files and no concrete theft or destructive action was found.
Mechanism
Automatic deployment of agent command and skill files.
AI rationale
The package has a real automatic OpenCode control-surface mutation, so it warrants a warning under the lifecycle policy. Source inspection found no self-dependency chain, stealth download in postinstall, credential harvesting, or concrete malicious payload.
Evidence
package.jsoncommands/plannotator-annotate.mdcommands/*.mdskills/plannotator/SKILL.md${XDG_CONFIG_HOME:-$HOME/.config}/opencode/commands/${XDG_CONFIG_HOME:-$HOME/.config}/opencode/skills/plannotator/
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The automatic postinstall hook creates OpenCode configuration directories and copies bundled commands and a skill into them.
- The installed command files instruct the host agent to run the Plannotator executable on behalf of users.
Evidence against
- The lifecycle hook only copies files shipped in this package; it does not download code or invoke the executable.
- No runtime dependency on this package itself appears in package.json.
- The reviewed Jina request is an explicit URL-annotation feature and uses only the configured Jina API key.
- The optional CallDiff installer verifies its downloaded archive with a pinned SHA-512 value and initially installs dependencies with scripts disabled.
