greprag@5.78.6: AI-agent control-surface risk | LPM Firewall

registry / greprag / 5.78.6

greprag@5.78.6

Private GrepRAG client for existing Claude Code, Codex, OpenCode, and Grok Build tenants.

AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package automatically adds or overwrites GrepRAG skill content in detected global Claude Code and Codex directories. This mutates agent control surfaces before the user runs an explicit setup command.

Static reason

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

Trigger

npm postinstall during package installation

Impact

The package can introduce or refresh instructions in installed Claude Code and Codex environments without separate consent.

Mechanism

automatic copying into global AI-agent skill registries

Policy narrative

The package manifest invokes its postinstall script. That script checks for existing Claude Code and Codex directories, then copies the bundled core skill into each detected global skills directory even if no prior GrepRAG skill exists. It also refreshes existing skill directories and an existing Claude document. This is automatic mutation of broad, foreign AI-agent instruction surfaces rather than user-invoked setup.

Rationale

Automatic postinstall writes into global Claude Code and Codex skill registries create an unconsented AI-agent control-surface change. This meets the install-hook abuse blocking policy.
