## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Can steer multiple AI coding agents and grant Claude Code project-local command permissions.

- **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:** 0.10.2
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. Installation mutates a consuming project's broad AI-agent instruction and configuration surfaces without an explicit user command. It also imports instruction content declared by installed dependencies.

## Security analysis

### Published attack-surface review

- **Summary:** Installation mutates a consuming project's broad AI-agent instruction and configuration surfaces without an explicit user command. It also imports instruction content declared by installed dependencies.

- **Trigger:** npm postinstall

- **Impact:** Can steer multiple AI coding agents and grant Claude Code project-local command permissions.

- **Evidence paths:** package.json, bin/install.js, lib/env.js, lib/agents.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-08T14:09:36.987Z

### AI review details

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

- **Mechanism:** postinstall project-wide AI-agent configuration and instruction injection

- **Attack narrative:** On npm installation, postinstall runs bin/install.js using INIT\_CWD. It calls setup(), which calls setupAgents() to write or replace AI-agent instruction files and Claude Code local permissions in the consuming project. The generated content incorporates local README text and ai.instructions from dependencies, creating an unconsented, broad agent-control surface.

- **Rationale:** This is a concrete unconsented postinstall mutation of foreign, broad AI-agent control surfaces, matching the block boundary. The absence of network exfiltration does not mitigate the control-surface hijack.

- **Files touched:** package.json, bin/install.js, lib/env.js, lib/agents.js, CLAUDE.md, AGENTS.md, GEMINI.md, .github/copilot-instructions.md, .cursor/rules/, .continue/rules/, .claude/settings.local.json

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json postinstall runs bin/install.js automatically., bin/install.js calls setup() against INIT\_CWD., lib/env.js invokes setupAgents() during setup., lib/agents.js writes CLAUDE.md, AGENTS.md, GEMINI.md, Copilot, Cursor, Continue, and Claude settings., Agent files incorporate README and dependency ai.instructions content., Claude settings grant shell commands in the target project.

- **Evidence against:** No network endpoint or credential-exfiltration code found in inspected paths., No remote payload loading, eval, or binary loading found in inspected paths.

## Public findings

Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel.

Public source snippet (untrusted):

```javascript
Install-time code directly mutates a foreign AI-agent control surface:
L5: export const managedFiles = [
L6: 'CLAUDE.md',
L7: 'AGENTS.md',
L8: 'GEMINI.md',
L9: '.github/copilot-instructions.md',
L10: '.cursor/rules/',
L11: '.continue/rules/',
L12: '.claude/settings.local.json',
L13: ];
...
L33: async function writeClaudeCode(path, sections, myself) {
L34: const filePath = join(path, 'CLAUDE.md');
L35: if (sections.length === 0) {
Write operation from lib/env.js:
L51: await rm('template', { recursive: true, force: true });
L52: await mkdir('template');
L53: await Promise.all(dirs.map(dir => mkdir(join('template', dir), { recursive: true })));
...
L197: }
L198: await mkdir(join(targetDir, '.git', 'info'), { recursive: true });

```javascript
L25: const exitCode = await new Promise((resolve, reject) => {
L26: const proc = exec('npm install --omit=optional', { cwd: path }, err => {
L27: if (err) {
```

Package source contains URL literals.

### 14. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%
