- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@realchemistry/auth-guard@2.2.13/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.postinstall = node scripts/install-skill.mjs
```

### 2. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 3. Medium: Network
- **Category:** Source

### 6. Critical: Ai Agent Control Hijack
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** scripts/install-skill.mjs
- **Public source:** [View source](<https://unpkg.com/@realchemistry/auth-guard@2.2.13/scripts/install-skill.mjs>)

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

Public source snippet (untrusted):

```javascript
L9: *      to wire the SDK in.
L10: *   2. Merge the bundled AGENTS.md snippet (skill/AGENTS.snippet.md) into
L11: *      the consumer project's AGENTS.md at the project root so the next
L12: *      agent that touches the project inherits the RC auth guardrails.
...
L14: * Both are idempotent: the skill file overwrites on every install (pinned to
L15: * the installed SDK version); the AGENTS.md merge replaces only the section
L16: * between <!-- BEGIN @realchemistry/auth-guard --> and <!-- END … --> markers,
L17: * leaving any other content in the user's AGENTS.md intact.
L18: *
...
L24: import {
L25: mkdirSync,
L26: copyFileSync,
```
