03SECURITYWHAT WE CHECKED
Security flags foundOur static scan found signals worth reviewing before you trust this with an agent. See exactly what, per check, below.
Telemetry disclosureUndisclosed egress detected.Static checks found network calls the docs do not mention. Disclosed telemetry is common and fine, silent telemetry is the finding.
Security tierTier 1, Contained.No network access and no credentials. Runs entirely on its own. What tiers mean
Install-time hooks & dependencies1 finding
HIGHpackage.json — npm 'prepare' lifecycle hook: install hook runs a command that fetches from the network, pipes to a shell, or runs an encoded/inline-interpreter command: the arbitrary-code-on-install supply-chain vector.

Permission scope breadthno flags
How much access it asks for versus what its job needs.
How to read this: these are static checks over the source at a point in time. They catch the patterns above, not everything. Absence of a flag is not absence of danger, and a tool that runs cleanly can still behave differently once installed. We do not call any tool simply "safe". Runtime-behavior checks are the next layer we are adding.
