## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Package-controlled instructions become available to multiple installed AI agents; Claude output behavior is changed by default.

- **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:** 4.0.12
- **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 multiple broad user-level AI-agent control surfaces without an explicit user command. It installs package-controlled skills/prompts across agent platforms and modifies Claude settings.

## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall mutates multiple broad user-level AI-agent control surfaces without an explicit user command. It installs package-controlled skills/prompts across agent platforms and modifies Claude settings.

- **Trigger:** npm install / global npm install

- **Impact:** Package-controlled instructions become available to multiple installed AI agents; Claude output behavior is changed by default.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T21:35:18.221Z

### AI review details

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

- **Mechanism:** cross-platform AI-agent skill and settings installation

- **Attack narrative:** Installing the package runs its postinstall script. That script deliberately fans out package-controlled skills into several user-level AI-agent directories, installs an agent prompt, and writes a Claude settings default, without requiring an explicit setup command or limiting changes to a package-owned surface. It also conditionally invokes an automatic project upgrade.

- **Rationale:** The lifecycle source establishes an unconsented postinstall mutation of foreign, broad AI-agent control surfaces. This meets the blocking policy despite no observed network exfiltration.

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

### Review decision

- **Verdict:** Malicious

- **Confidence:** 97.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs scripts/install-skills.mjs as postinstall., Postinstall fans out bundled skills to ~/.claude, ~/.codex, ~/.cursor, ~/.trae and other agent directories., Postinstall writes bundled agent prompts and output styles, then sets ~/.claude/settings.json outputStyle., Postinstall creates ~/.peaks/config.json and can spawn \`peaks upgrade --auto\` on detected project state.

- **Evidence against:** No package-controlled network request or credential exfiltration was found in inspected lifecycle code., OCR endpoint is a user-supplied configuration template, not an install-time endpoint.
