## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Package-supplied instructions become available to Claude Code and Codex without explicit setup consent.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 5.60.6
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. npm postinstall mutates the global Claude Code and Codex AI-agent skill control surfaces. It installs package-controlled instructions that agent clients may load in future sessions.

## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall mutates the global Claude Code and Codex AI-agent skill control surfaces. It installs package-controlled instructions that agent clients may load in future sessions.

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

- **Impact:** Package-supplied instructions become available to Claude Code and Codex without explicit setup consent.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-07-26T19:06:17.402Z

### AI review details

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

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

- **Attack narrative:** Installing the package invokes postinstall automatically. When Claude Code or Codex directories exist, the script recursively copies the bundled greprag skill into each platform's global skill registry, where its instructions can influence later agent sessions. This is an unconsented install-time mutation of foreign AI-agent control surfaces.

- **Rationale:** Direct inspection confirms the postinstall drop into ~/.claude and ~/.codex, not merely scanner inference. This meets the firewall block boundary for unconsented postinstall mutation of broad foreign AI-agent control surfaces.

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

### Review decision

- **Verdict:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs scripts/postinstall.js automatically after install., scripts/postinstall.js detects ~/.claude and ~/.codex then copies bundled skills into their global skills registries., The automatic copy creates ~/.claude/skills/greprag and ~/.codex/skills/greprag without an explicit setup command., skill/greprag/SKILL.md supplies agent instructions and executable CLI workflows.

- **Evidence against:** Postinstall only acts when the respective agent home directory already exists., Later hook/plugin and startup setup is behind explicit greprag init commands or prompts.
