The harvest uses existing API credentials in requests to an operator-configurable endpoint, and remote harvesting is enabled by default when a key is available. This warrants a warning for conditional credential exposure; the inspected install hook does not establish an unconsented machine-wide configuration change.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

A session invokes the harvest path while a remote endpoint and API key are configured and harvesting has not been opted out.

Impact

A remotely configured recipient may receive the existing service credential along with the harvest request.

Mechanism

The harvest selects its endpoint from TOKEN_OPTIMIZER_HARVEST_ENDPOINT and attaches the API key in an authorization header according to the endpoint dialect.

Network endpoints1

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The harvest reads an API key from TOKEN_OPTIMIZER_API_KEY or ANTHROPIC_API_KEY.
The harvest sends requests to a configurable endpoint and attaches the credential in an authorization header based on endpoint dialect.
Remote harvesting is enabled by default when a key is present, unless opted out.
The package's postinstall runs setup only when TOKEN_OPTIMIZER_AUTO_INSTALL is enabled; otherwise it reports that no machine changes were made.

Evidence against

The default harvest endpoint is Anthropic's Messages API, and the HTTP request is only made when the harvesting path runs.
The credential exposure risk depends on the user configuring a remote endpoint that is not bound to the credential's intended service.
