@plannotator/opencode@0.28.48
Plannotator plugin for OpenCode - interactive plan review with visual annotation
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe default runtime sends undisclosed usage telemetry to the package service, which warrants a warning under the telemetry rule. The install hook also installs the package’s own OpenCode guidance; neither behavior shows credential theft or unrelated data collection.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A Plannotator CLI action schedules the ping; package installation runs postinstall for eligible package managers.
Impact
The service receives limited usage information without disclosure in the inspected package documentation, and installation adds package-specific agent guidance.
Mechanism
The embedded runtime POSTs version and usage-cohort fields to the package service. Postinstall copies command and skill files into the OpenCode config directory.
AI rationale
The default runtime sends undisclosed usage telemetry to the package service, which warrants a warning under the telemetry rule. The install hook also installs the package’s own OpenCode guidance; neither behavior shows credential theft or unrelated data collection.

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- On a Plannotator review action, the embedded runtime schedules a daily ping to the package service.
- The ping contains the package version, a usage-age week, tool name, and first-use flag.
- The postinstall script copies this package’s commands and skill into the user’s OpenCode config.
- Telemetry can be disabled with DO_NOT_TRACK or NO_ANON_PING.
Evidence against
- The observed ping payload contains no credentials, file contents, paths, hostnames, or account identifiers.
- The install-time writes are limited to this package’s own OpenCode commands and skill.
