Security flags foundOur static scan found signals worth reviewing before you trust this with an agent. See exactly what, per check, below.

Install-time hooks & dependencies5 findings
HIGHpackage.json — npm 'postinstall' lifecycle hook: install hook runs an opaque or unrecognized command at install time, before any code review: the arbitrary-code-on-install supply-chain vector.
HIGHpackage.json — npm 'prepare' lifecycle hook: install hook runs an opaque or unrecognized command at install time, before any code review: the arbitrary-code-on-install supply-chain vector.
HIGHapps/web/package.json — npm 'preinstall' lifecycle hook: install hook runs an opaque or unrecognized command at install time, before any code review: the arbitrary-code-on-install supply-chain vector.
INFOapps/web/package.json — npm 'postinstall' lifecycle hook: install hook runs a build at install (recognized toolchain), standard for a compiled package. Recorded for completeness, not a flag.
INFOapps/web/package.json — High dependency count (215). A breadth hint: a larger transitive surface to trust. Not a defect by itself.

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.
