## What it does

The skill reads the `SKILL.md` of another skill that asks for the `network` permission and lists the domains it declares. Then it looks for what the author left out: connections to raw IPs, DNS tunneling, WebSockets to unknown servers, non-standard ports, obfuscated URLs, addresses built at runtime from environment variables.

A separate section covers exfiltration patterns. Reading a file and posting its contents, leaking `process.env` values through query strings, hiding secrets in base64 headers, slow drip exfiltration spread across many requests. There is also a runtime checklist: every request hits a declared endpoint, no file contents or credentials in the body, outbound volume fits the task.

The rules are strict. The skill treats `network + fileRead` and `network + shell` as critical by default and assumes exfiltration risk. Dynamic endpoints, raw IPs or URL shorteners get a DENY recommendation. When in doubt, it suggests sandboxing first with `--network none`. It never runs the skill under review — analysis only, unless you ask for a controlled test.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add UseAI-pro/openclaw-skills-security --skill network-watcher -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/network-watcher/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/network-watcher/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add UseAI-pro/openclaw-skills-security --skill network-watcher -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/network-watcher/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add UseAI-pro/openclaw-skills-security --skill network-watcher -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/network-watcher/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install UseAI-pro/openclaw-skills-security network-watcher
```

2. **Manually: put the files in place**
- File: `.github/skills/network-watcher/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add UseAI-pro/openclaw-skills-security --skill network-watcher -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/UseAI-pro/openclaw-skills-security --path skills/network-watcher
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/network-watcher/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add UseAI-pro/openclaw-skills-security --skill network-watcher -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/UseAI-pro/openclaw-skills-security/tree/HEAD/skills/network-watcher/SKILL.md

## When to use it
- check where a skill sends data before installing it
- spot file and environment variable leaks in third-party code
- tell a package registry lookup apart from a tunnel
- decide whether to grant a skill the `network` permission
- catch background connections opened after a task finishes

## Example prompts
- audit the network requests of this skill before I install it
- list the declared endpoints in this SKILL.md
- does this skill contain any exfiltration patterns

# Network Watcher

You are a network security auditor for OpenClaw. When a skill requests `network` permission, you analyze what connections it makes and whether they are legitimate.

## Why Network Monitoring Matters

Network access is the primary vector for data exfiltration. A skill that can read files AND make network requests can steal your source code, credentials, and environment variables by sending them to an external server.

## Pre-Install Network Audit

Before a skill with `network` permission is installed, analyze its SKILL.md for:

### 1. Declared Endpoints

The skill should explicitly list every domain it connects to:

```
NETWORK AUDIT
=============
Skill: <name>

DECLARED ENDPOINTS:
  api.github.com — fetch repository metadata
  registry.npmjs.org — check package versions

UNDECLARED NETWORK ACTIVITY:
  [NONE FOUND / list suspicious patterns]
```

### 2. Red Flags in Network Usage

**Critical — block immediately:**
- Connections to raw IP addresses (`http://185.143.x.x/`)
- Data sent via DNS queries (DNS tunneling)
- WebSocket connections to unknown servers
- Connections using non-standard ports
- Encoded/obfuscated URLs
- Dynamic URL construction from environment variables

**High — require justification:**
- Connections to personal servers (non-organization domains)
- POST requests with file content in the body
- Multiple endpoints on different domains
- Connections to URL shorteners or redirectors
