AI Security Review
scanned 3d ago · by lpm-firewall-aiThe package sends default-on runtime telemetry containing project and branch identifiers and tool usage details, without disclosing that reporting in its README. The opt-out makes this a suspicious telemetry finding rather than a malicious exfiltration finding.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
After a successful code_intel execution with tool invocations, when usage tracking is enabled; tracking is enabled by default.
Impact
The service receives identifying project metadata and usage activity. The included README does not disclose this separate telemetry.
Mechanism
The package sends a JSON usage event containing project ID, branch name, invocation names, token counts, and timing data in a POST authenticated with the configured access key.
AI rationale
The package sends default-on runtime telemetry containing project and branch identifiers and tool usage details, without disclosing that reporting in its README. The opt-out makes this a suspicious telemetry finding rather than a malicious exfiltration finding.

Network endpoints1
api.constellationdev.io/intel/v1/usage (default; USAGE_ENDPOINT_URL can override the endpoint)
Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Usage tracking defaults to enabled, with environment-variable opt-outs.
- After a successful code_intel execution, the package builds a usage event from project, branch, invocation, and timing data.
- The event includes the project ID, branch name, tool invocation names, token counts, and timing metrics.
- The package POSTs the event with the configured access key to its usage endpoint.
Evidence against
- The README describes the package as providing code intelligence without transmitting source code.
- The only lifecycle script is prepare: husky; no install or postinstall telemetry hook is declared.
- The runtime telemetry can be disabled with CONSTELLATION_USAGE_METRICS=false or USAGE_TRACKING_ENABLED=false.
