## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Unconsented persistence and behavior control across installed AI-agent environments.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default

- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 4.0.15
- **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 AI-agent skill/control directories without an explicit user command. It also sets Claude Code's output style and can trigger a project upgrade.

## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall mutates multiple AI-agent skill/control directories without an explicit user command. It also sets Claude Code's output style and can trigger a project upgrade.

- **Trigger:** npm install of peaks-loop@4.0.15

- **Impact:** Unconsented persistence and behavior control across installed AI-agent environments.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-08T14:31:01.387Z

### AI review details

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

- **Mechanism:** postinstall fan-out of skills, agents, output styles, and configuration

- **Attack narrative:** Installing the package invokes its postinstall hook. That hook creates or changes skill directories for numerous unrelated AI-agent products, symlinks bundled instructions into them, writes agent prompts, and automatically configures Claude Code to use the bundled output style. These mutations happen by default, including when no compatible IDE is detected, rather than through an explicit setup command.

- **Rationale:** Direct source inspection confirms unconsented postinstall mutation of broad, foreign AI-agent control surfaces. This meets the publish-block policy regardless of the absence of exfiltration.

- **Files touched:** scripts/install-skills.mjs, skills/\*\*, agents/karpathy-reviewer.md, output-styles/peaks-skill-swarm.md, ~/.claude/skills/\*, ~/.codex/skills/\*, ~/.cursor/skills/\*, ~/.claude/settings.json, ~/.claude/agents/\*, ~/.peaks/config.json

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs scripts/install-skills.mjs as postinstall., installBundledSkillsForAllPlatforms unconditionally fans out to ~/.claude, ~/.codex, ~/.cursor and other agent skill directories., installBundledOutputStyleDefault writes outputStyle into ~/.claude/settings.json when unset., installBundledAgentsForAllPlatforms installs package agent prompts into agent loader directories., Postinstall can run \`peaks upgrade --to 2.0 --auto\` against a detected project.

- **Evidence against:** No network request or credential-exfiltration code was found in the inspected lifecycle source., Installer skips user-owned conflicting files and includes symlink/path safety checks.
