AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has a concrete install-time AI-agent control-surface write into the consuming project. No separate network or credential-theft behavior was found, but the unconsented postinstall mutation meets the block boundary.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
npm install of the package in a non-global project
Impact
Changes project AGENTS.md and .codex agent/config behavior.
Mechanism
postinstall template materialization into INIT_CWD
Policy narrative
Installing the package invokes postinstall, resolves the caller's project through INIT_CWD, and recursively materializes templates at that root. Those templates include AGENTS.md and .codex configuration/agent definitions, altering the host project's AI-agent instructions without an explicit setup command.
AI rationale
The package has a concrete install-time AI-agent control-surface write into the consuming project. No separate network or credential-theft behavior was found, but the unconsented postinstall mutation meets the block boundary.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 94.0% confidence with low false-positive risk.
Evidence for policy risk
- postinstall runs automatically for non-global installs.
- It uses INIT_CWD as the consuming project root.
- Installer recursively copies bundled templates into that project root.
- Templates include .codex agent configuration and AGENTS.md control instructions.
Evidence against
- No network/exfiltration primitives or endpoints found.
- No credential harvesting, remote payload loading, or obfuscated code found.
