This silently adds package-controlled instructions to foreign AI-agent control surfaces. - **Trigger:** npm install when a Claude Code or Codex home directory exists - **Impact:** Persistent unconsented control of future agent instruction loading; the injected skill routes use toward GrepRAG services. - **Evidence paths:** package.json, scripts/postinstall.js, skill/greprag/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-08-15T21:12:58.348Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall skill-registry injection - **Attack narrative:** Installing the package invokes its postinstall hook. If ~/.claude or ~/.codex already exists, the hook creates the platform skills directory as needed and copies the bundled greprag skill there, including a new core skill when absent. This is an unconsented install-time mutation of foreign AI-agent instruction registries, causing subsequent agent sessions to load package-controlled guidance and setup flows. - **Rationale:** The lifecycle hook performs automatic, persistent writes to foreign Claude Code and Codex skill registries, which meets the install-time AI-agent control-surface hijack boundary. Detection-only gating does not provide user consent. - **Files touched:** scripts/postinstall.js, skill/greprag, ~/.claude/skills/greprag, ~/.codex/skills/greprag - **Network endpoints:** https://api.greprag.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., Postinstall targets existing Claude and Codex home directories., It creates and copies the bundled core skill into those foreign agent skill registries without consent., The installed skill directs agents to GrepRAG’s remote memory and messaging service. - **Evidence against:** The postinstall limits targets to detected agent directories and catches errors., No credential theft or unrelated shell execution was found in the inspected lifecycle script. ## Public findings ### 1.
