crtr — agent runtime with memory, plugins, and marketplaces

AI Security Review

scanned 8d ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. First CLI use automatically installs companion agent extensions and marketplace plugins. This establishes a first-party extension lifecycle risk, without a confirmed malicious attack.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

First CLI invocation without a completion marker, or confirmed explicit setup; shell execution requires a matching slash command.

Impact

Installed extensions can influence agent prompts and execute command-provided shell blocks. No covert exfiltration or block-eligible control hijack was established.

Mechanism

Companion installation updates Pi package settings; resource discovery writes command shims, and command invocation expands embedded shell blocks. Content updates run automatically only under the apply preference.

AI rationale

Source establishes automatic first-party agent extension setup and command execution capability, supporting a behavior-specific warning. No inspected behavior establishes malicious intent or unconsented npm lifecycle mutation of a foreign agent control surface.

Evidence

dist/cli.jsdist/commands/sys/setup-core.jsdist/commands/sys/setup-wizard.jsdist/builtin-pi-packages/pi-crtr-extensions/extensions/claude-plugin-commands.tsdist/core/auto-update.jssettings.json.plugin-command-shims

Decision evidence

public snapshot

AI called this Suspicious at 93.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The CLI automatically reconciles companion packages on first use; a saved completion marker or CRTR_NO_AUTO_INIT disables this path.
First-run reconciliation installs missing companion extensions and marketplace plugins, and records the package-owned extensions in Pi settings.
The companion extension creates command shims and executes embedded shell blocks when indexed slash commands are invoked.
The explicit setup wizard requires confirmation before submitting pending installations.
Automatic content updates require the saved apply setting; installing extensions does not itself establish that preference.
The npm postinstall invokes runtime installation and renderer provisioning; the inspected agent integration activates through CLI initialization.

Evidence against

The extensions belong to the package's agent runtime, and shell expansion follows slash-command invocation.
The indicated viewer location labels agent resource files for display.
No concrete credential theft or malicious install-time agent control hijack was established.
