AI Security Review

scanned 12d ago · by lpm-firewall-ai

The postinstall hook automatically invokes setup across platforms, which can modify agent configuration and rules. The inspected behavior is package-aligned first-party setup, so it warrants a warning rather than a malicious verdict.

Static reason

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

Trigger

Installing the package through npm invokes its postinstall hook.

Impact

Agent clients may load the CodeSift server and its package-owned instructions after installation.

Mechanism

The hook runs setup for all platforms, which can write the package’s MCP configuration and managed agent rules.

AI rationale

Evidence

dist/postinstall.jsdist/cli/setup/codex.jsdist/cli/setup/rules.js~/.codex/config.tomlAGENTS.mdGEMINI.md

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The postinstall hook automatically runs setup for all supported platforms.
Codex setup writes configuration under the user’s .codex directory and ensures an approval setting for the package’s own server entry.
The rules setup maps platforms to package-owned files and appends managed rules to the project’s AGENTS.md or GEMINI.md.
The package configuration behavior is an agent setup capability; no separate concrete attack was established from the inspected source.

Evidence against

The inspected setup code targets CodeSift’s own MCP entry and uses marked package-owned rules blocks.
No network endpoint or unrelated dependency approval grant was established in the inspected excerpts.
