savant-code@0.0.31
Multi-Agent AI Coding Assistant with ECHO Protocol
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe launcher sends a potentially identifying home-directory path in runtime error telemetry to a configured PostHog endpoint. The environment-variable gate limits when this occurs, but the path is still identifying data, 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
A download failure occurs while a PostHog API key and host environment variable are set.
Impact
The home-directory path can identify the local user or account to the analytics service.
Mechanism
The launcher posts the failure event and `anonymous-${CONFIG.homeDir}` to the configured host’s `/capture/` endpoint.
AI rationale
The launcher sends a potentially identifying home-directory path in runtime error telemetry to a configured PostHog endpoint. The environment-variable gate limits when this occurs, but the path is still identifying data, so this warrants a warning rather than a block.
Evidence

Network endpoints3
configured PostHog host from SAVANT_CODE_POSTHOG_HOST or NEXT_PUBLIC_POSTHOG_HOST_URLregistry.npmjs.orggithub.com
Decision evidence
public snapshotAI called this Suspicious at 93.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Launcher telemetry activates when a PostHog API key and host are supplied through environment variables.
- The event includes `CONFIG.homeDir` as its distinct ID, along with update error details and platform information.
- The launcher posts the event to the configured host’s `/capture/` endpoint after a download failure.
Evidence against
- The manifest declares `prepack` and `postpack` scripts, with no install lifecycle hook.
- The entry point calls `launcher.main()` only when run as the CLI.
- The launcher downloads Savant Code releases and asks for approval before installing a staged update interactively.
