greprag@5.78.3

GrepRAG — agent memory for Claude Code, Codex, OpenCode, and Grok Build.

AI Security Review

scanned 19d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package automatically adds or refreshes its skill in existing Claude Code and Codex agent registries. This modifies AI-agent control surfaces without a separate setup command or consent step.

Static reason

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

Trigger

npm postinstall after package installation when ~/.claude or ~/.codex exists.

Impact

The package's agent instructions become available to Claude Code or Codex sessions and may influence subsequent agent behavior.

Mechanism

Recursive installation of bundled agent skills into existing global skill directories.

Policy narrative

The package declares an automatic postinstall hook. When a user already has Claude Code or Codex installed, that hook creates or overwrites the package's core skill under the corresponding global agent skills directory. The copied SKILL.md provides instructions for future agent sessions. This is an unconsented install-time mutation of foreign AI-agent control surfaces.

AI rationale

The automatic lifecycle hook writes package-controlled instructions into existing global Claude Code and Codex skill registries. That concrete install-time control-surface mutation meets the blocking policy even though the inspected installer does not make network requests.
