## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall mutates detected third-party AI-agent control surfaces. It installs package-authored instructions into Codex and Claude Code skill directories without an explicit setup command.

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

- **Impact:** Package-authored instructions become available to installed AI agents and existing auxiliary skills are overwritten on refresh.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-07-26T19:06:19.409Z

### AI review details

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

- **Mechanism:** automatic AI-agent skill deployment

- **Attack narrative:** On npm postinstall, the package detects existing Codex or Claude Code homes and copies its bundled skill instructions into their global skill registries. This happens without an explicit greprag setup command; it also refreshes any pre-existing bundled auxiliary skills. The injected GrepRAG skill directs agent configuration and operational commands, creating an unconsented AI-agent control-surface mutation.

- **Rationale:** The install hook concretely writes package-controlled AI-agent instructions into foreign global agent directories. This meets the blocking policy for unconsented postinstall mutation of a broad AI-agent control surface.

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

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs scripts/postinstall.js on install., scripts/postinstall.js automatically copies bundled skills into detected ~/.codex/skills and ~/.claude/skills., The install hook creates the core greprag skill when absent and refreshes existing non-core skills without user command., Bundled skill instructions direct agent setup and operational behavior in skill/greprag/SKILL.md.

- **Evidence against:** scripts/postinstall.js performs no network requests or shell execution., Codex hook registration and login persistence are behind explicit greprag init/codex commands.
