What this skill does

# ClawSec Feed 📡

Security advisory feed monitoring for AI agents. Subscribe to community-driven threat intelligence and stay informed about emerging threats.

This feed is automatically updated daily with CVEs related to OpenClaw, clawdbot, and Moltbot from the NIST National Vulnerability Database (NVD).

**An open source project by [Prompt Security](https://prompt.security)**

## Installation Options

You can get clawsec-feed in two ways:

### Option A: Bundled with ClawSec Suite (Recommended)

**If you've installed clawsec-suite, you may already have this!**

ClawSec-feed is bundled alongside ClawSec Suite to provide crucial CVE and threat intelligence information. When you install the suite, if you don't already have the feed installed, it will be deployed from the bundled copy.

**Advantages:**
- Convenient - no separate download needed
- Standard location - installed to `~/.openclaw/skills/clawsec-feed/`
- Preserved - if you already have feed installed, it won't be overwritten
- Single verification - integrity checked as part of suite package

### Option B: Standalone Installation (This Page)

Install clawsec-feed independently without the full suite.

**When to use standalone:**
- You only need the advisory feed (not other suite components)
- You want to install before installing the suite
- You prefer explicit control over feed installation

**Advantages:**
- Lighter weight installation
- Independent from suite
- Direct control over installation process

Continue below for standalone installation instructions.

Installation Steps:
Agents should review scripts before execution!


```bash
# Get latest clawsec-feed release tag
LATEST_TAG=$(curl -sSL https://api.github.com/repos/prompt-security/ClawSec/releases | \
  jq -r '[.[] | select(.tag_name | startswith("clawsec-feed-v"))][0].tag_name')

# Download SKILL.md from latest release
SKILL_URL="https://github.com/prompt-security/clawsec/releases/download/$LATEST_TAG/SKILL.md"
curl -sSL --fail --show-error "$SKILL_URL"
```

Once you have this skill file, proceed to **[Deploy ClawSec Feed](#deploy-clawsec-feed)** below.

## Deploy ClawSec Feed

Installation steps:

### Step 1: Create skill directory and save this file

```bash
mkdir -p ~/.openclaw/skills/clawsec-feed
# Save this SKILL.md as SKILL.md in the directory above
```

### Step 2: Install skill files

```bash
# Get latest release tag with retry logic
