crtr — agent runtime with memory, plugins, and marketplaces

AI Security Review

scanned 6d ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. First CLI use automatically installs first-party extensions and marketplace plugins and changes agent settings. This establishes an extension lifecycle capability, but no confirmed malicious attack.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

First CLI invocation without a completion marker, unless CRTR_NO_AUTO_INIT=1; explicit setup and configured background updates provide additional activation paths.

Impact

Local agent capabilities and executable plugin content can change automatically; the default settings destination belongs to crouter's terminal runtime.

Mechanism

First-run reconciliation installs missing packages and records bundled extension discovery patterns in agent settings. The extension creates command shims and executes shell expansion for invoked commands.

AI rationale

Source supports a warning for automatic first-party agent extension setup and configurable content updates. It does not establish malicious intent or unconsented npm-install mutation of a foreign agent control surface.

Decision evidence

public snapshot

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

Evidence for warning

dist/cli.js automatically reconciles first-run setup unless disabled, already completed, or running from a source checkout.
setup-core.js installs missing bundled extensions and official marketplace plugins during first-run reconciliation.
Setup writes extension entries to agent settings; the default destination is crouter's terminal app home, with an environment override.
The bundled Claude command extension writes discovery shims and expands shell blocks when indexed slash commands are invoked.
Explicit setup confirms selections; background content updates depend on the configured apply mode rather than wizard confirmation alone.
The inspected postinstall caller stages the runtime and provisions the renderer; it does not call agent setup.

Evidence against

No credential exfiltration or malicious intent was established.
The flagged viewer location contains guidance filenames for read-tool rendering, not configuration mutation.
The extension setup targets a first-party runtime by default and occurs on CLI use, supporting a warning rather than an install-hook block.
