## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Changes foreign AI-agent control surfaces and defaults; also launches a project upgrade when legacy state is detected.

- **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:** 4.0.23
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. On npm installation, the package mutates home-directory AI-agent skill, prompt, output-style, and settings locations. The behavior spans multiple platforms and is activated without an explicit setup command.

## Security analysis

### Published attack-surface review

- **Summary:** On npm installation, the package mutates home-directory AI-agent skill, prompt, output-style, and settings locations. The behavior spans multiple platforms and is activated without an explicit setup command.

- **Trigger:** npm postinstall

- **Impact:** Changes foreign AI-agent control surfaces and defaults; also launches a project upgrade when legacy state is detected.

- **Evidence paths:** package.json, scripts/install-skills.mjs, agents/karpathy-reviewer.md, output-styles/peaks-skill-swarm.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-15T11:07:32.334Z

### AI review details

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

- **Mechanism:** automatic cross-platform AI-agent skill and configuration installation

- **Attack narrative:** Installing the package triggers its postinstall script. That script fans out bundled skills into multiple vendors' home-directory agent directories, writes a Claude sub-agent prompt and output style, sets Claude's outputStyle default, and may invoke an upgrade against the current project. These are unconsented install-time mutations of broad foreign AI-agent control surfaces.

- **Rationale:** Source directly confirms postinstall-triggered multi-platform agent configuration writes. This meets the blocking policy for unconsented install-time foreign/broad AI-agent control-surface mutation.

- **Files touched:** scripts/install-skills.mjs, ~/.claude/skills/\*, ~/.codex/skills/\*, ~/.cursor/skills/\*, ~/.claude/agents/\*.md, ~/.claude/settings.json, ~/.peaks/config.json

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** npm postinstall runs install-skills.mjs automatically., Postinstall defines home-directory skill targets for multiple foreign AI-agent platforms, including Codex and Cursor., It fans out bundled skills to every configured platform and creates symlinks in their skill directories., It copies bundled sub-agent prompts into ~/.claude/agents/., It writes outputStyle into ~/.claude/settings.json when absent., It can auto-run peaks upgrade against a detected project during installation.

- **Evidence against:** No lifecycle-network endpoint or credential-exfiltration code was identified in the inspected installer., Existing user-authored skill, agent, and output-style files are generally skipped unless marked package-managed.
