crtr — agent runtime with memory, plugins, and marketplaces

AI Security Review

scanned 11d ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. A Pi extension bridges Claude command and skill files into Pi slash commands and can execute their embedded shell blocks. The package also patches a pinned Pi dependency during npm postinstall.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Pi resource discovery followed by a matching slash-command input; the dependency patch runs during npm postinstall.

Impact

A user-installed Claude command or plugin can obtain shell execution through the enabled Pi extension. No confirmed covert exfiltration or remote attack was found.

Mechanism

The extension rebuilds a user Pi shim directory from Claude command sources, then expands shell blocks for indexed commands. Postinstall rewrites a known Pi dependency source file after version checks.

AI rationale

This is a guarded agent-extension lifecycle and shell-execution capability, not evidence of malware. It warrants a warning because the extension imports and executes shell-bearing commands from another agent ecosystem.

Evidence

dist/builtin-pi-packages/pi-crtr-extensions/extensions/claude-plugin-commands.tsscripts/postinstall.mjsscripts/patch-pi-tree-root-ordering.mjs

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence with false-positive risk.
