AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package is not malicious based on the reviewed entry points, but its shipped build helper deletes user-level npm and Yarn configuration without explaining or requesting that cleanup. Because the helper is not an install hook, this is a suspicious destructive side effect rather than install-time abuse.
Static reason
No blocking static signals were detected.
Trigger
A user or build process explicitly runs build.sh.
Impact
Existing npm and Yarn configuration is lost.
Mechanism
The script runs rm -f on ~/.npmrc and ~/.yarnrc before installing dependencies and building.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The shipped build.sh unconditionally removes ~/.npmrc and ~/.yarnrc when invoked, then installs build dependencies.
- The package exposes build.sh separately; its npm build script only runs Babel, so the destructive cleanup is not an install lifecycle action.
Evidence against
- The manifest has no preinstall, install, or postinstall script.
- The SDK sends requests through its configured Files.com API base URL, consistent with its stated purpose.
- The AI CLI wrapper delegates to an existing files-cli binary and does not download or execute remote code.
