# SkillScanner — Security Scanner for ClawHub Skills

> **"Trust, but verify."**

SkillScanner checks ClawHub skill safety by calling the scan API. You provide the skill URL; the API returns status and severity. Proceed only when the verdict is **SAFE**.

---

## How to Scan a Skill (Agent Instructions)

1. **Run the lookup** with the real skill URL (format: `https://clawhub.ai/author/skill-name`):

   ```bash
   curl --request POST --url "https://ai.gendigital.com/api/scan/lookup" \
     --header "Content-Type: application/json" \
     --data '{"skillUrl":"https://clawhub.ai/AUTHOR/SKILL_SLUG"}'
   ```

   Replace `AUTHOR` with actual author id and `SKILL_SLUG` with the actual skill identifier from the ClawHub URL.

2. **Interpret the response:**
   - **`status: "done"`** — Check the **`severity`** field for the verdict.
   - **`status: "analysis_pending"`** — The skill is awaiting manual review. Do not treat as safe; advise the user that the skill is pending review.

3. **Proceed or advise caution:**
   - **Proceed** only if **`severity` is `SAFE`**.
   - If severity is anything else (e.g. `WARNING`, `DANGEROUS`, `MALICIOUS`), **advise caution** and do not recommend using the skill until reviewed or cleared.

## Quick Start

```bash
# Example: scan a skill by its ClawHub URL
curl --request POST --url "https://ai.gendigital.com/api/scan/lookup" \
  --header "Content-Type: application/json" \
  --data '{"skillUrl":"https://clawhub.ai/author/skill-name"}'
```

Parse the JSON response: use `status` and `severity` as above.

## API Response Logic

| `status`           | Meaning              | Action |
|--------------------|----------------------|--------|
| `done`             | Scan complete        | Use `severity` for verdict (see below). |
| `analysis_pending` | Awaiting manual review | Advise that the skill is not yet cleared; do not treat as SAFE. |

| `severity` (when `status` = `done`) | Recommendation |
|-------------------------------------|----------------|
| **SAFE**                            | OK to proceed. |
| Any other value                     | Advise caution; do not recommend use until reviewed. |

## Why This Matters

Skills can run code and access your environment. Risks include:

| Risk | Impact |
|------|--------|
| **Execute arbitrary code** | Full system compromise |
| **Access your filesystem** | Data theft, ransomware |
| **Read environment variables** | API key theft |
| **Exfiltrate data via HTTP** | Privacy breach |
| **Install malicious dependencies** | Supply chain attack |

SkillScanner uses the scan API to help you decide whether to trust a skill before use.

---

## Limitations

- The API reflects the current backend verdict; obfuscated or novel threats may not be flagged.
- `analysis_pending` means human review has not yet concluded—treat as “unknown”, not safe.

Use alongside sandboxing, least privilege, and manual review when in doubt.
