## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall mutates existing Claude Code and Codex global agent-control directories. It installs a package-controlled skill that changes agent behavior for broad prompt triggers.

- **Trigger:** npm install when ~/.claude or ~/.codex already exists

- **Impact:** Unconsented persistent instruction/control-surface modification for installed AI-agent environments.

- **Evidence paths:** package.json, scripts/postinstall.js, skill/greprag/SKILL.md, dist/commands/codex-startup.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-26T19:06:18.532Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Automatic global AI-agent skill injection

- **Attack narrative:** Installing the package automatically detects global Claude Code and Codex homes and copies its bundled greprag skill into their skills directories. The installed skill supplies extensive standing instructions and invokes GrepRAG setup, memory, messaging, and email-related commands in response to broad user requests. This is an unconsented postinstall mutation of foreign global AI-agent control surfaces.

- **Rationale:** Direct inspection confirms the lifecycle script writes package-controlled instructions into existing ~/.claude and ~/.codex installations. This meets the blocking policy regardless of the package’s stated product purpose.

- **Files touched:** scripts/postinstall.js, skill/greprag, ~/.claude/skills/greprag, ~/.codex/skills/greprag

- **Network endpoints:** https://api.greprag.com

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs scripts/postinstall.js automatically., scripts/postinstall.js detects existing ~/.claude and ~/.codex directories., Postinstall copies bundled skill/greprag into each platform’s global skills directory without user setup command., skill/greprag/SKILL.md injects broad agent instructions and routes prompts to GrepRAG commands/setup., The installed skill directs agents toward API-backed messaging and real-email commands.

- **Evidence against:** Postinstall performs no network requests or child-process execution., Codex hook and startup persistence installation is behind explicit CLI commands, not postinstall.
