crtr — agent runtime with memory, plugins, and marketplaces

AI Security Review

scanned 3mo ago · by lpm-firewall-ai

Source inspection does not support the scanner's malicious verdict. The cross-host configuration writes are user-triggered and guarded, but warrant a warning under the firewall policy for explicit AI-agent control-surface mutation.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

User runs a crtr CLI command.

Impact

Adds or updates package-owned command templates in existing host configuration directories.

Mechanism

Marker-guarded AI-agent command-template export

AI rationale

Evidence

package.jsonscripts/postinstall.mjsdist/cli.jsdist/core/host-exports/export.jsdist/core/host-exports/builtins.jsdist/core/self-update.js

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

dist/cli.js invokes host export provisioning on CLI runs.
dist/core/host-exports/export.js writes marker-owned templates to existing ~/.claude and ~/.pi agent command directories.
scripts/postinstall.mjs patches a version-pinned dependency file during install.

Evidence against

Postinstall only alters one exact pi UI ordering expression; no network or credential access.
Host exports require an explicit CLI invocation, existing host roots, and do not overwrite markerless user files.
Runtime self-update and plugin installation are exposed through user-invoked commands.
No source evidence of stealth exfiltration, remote payload execution, or destructive foreign-agent takeover.
