crtr — agent runtime with memory, plugins, and marketplaces

AI Security Review

scanned 6d ago · by lpm-firewall-ai

No confirmed malicious attack surface. The package is an agent runtime/CLI with user-invoked local process, web bridge, plugin, marketplace, and update features that match its stated functionality.

Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Install runs postinstall; runtime features require explicit crtr CLI/web/setup/update commands.
Impact
No unconsented install-time execution beyond a console message; runtime command execution/network access is user-invoked and guarded where remote-capable.
Mechanism
Package-aligned agent runtime and local control bridge
Rationale
Static inspection found risky primitives, but they are aligned with a CLI agent runtime and are not activated at install/import; the only lifecycle hook prints guidance. Network, update, filesystem, and child-process behavior require explicit CLI/web actions or user configuration and no credential exfiltration or covert payload was found.

Decision evidence

public snapshot
AI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for block
  • dist/core/bootstrap.js auto-clones official marketplace on CLI use, not install
  • dist/core/auto-update.js can spawn npm/crtr updates only if user config sets apply
  • dist/clients/web/server.js exposes exec/file/http bridge when user starts web server
Evidence against
  • scripts/postinstall.mjs only prints setup guidance and exits; no install-time download or mutation
  • dist/index.js is a side-effect-free export barrel
  • Default auto_update in dist/types.js is notify/notify, not apply
  • Web server defaults to 127.0.0.1 and requires --token for non-loopback binds
  • dist/core/view/transport-local.js exec/file/http behavior is behind user-invoked web bridge
  • No credential harvesting, exfiltration endpoint, persistence, or destructive install behavior found
