# ClawSec ClawHub Checker

Adds a reputation gate on top of the `clawsec-suite` guarded installer.

## Vercel Skills Installation

Install with the Vercel Skills CLI for this harness:

```bash
npx skills add prompt-security/clawsec --skill clawsec-clawhub-checker -a openclaw -y
```

## Operational Notes

- Required runtime: `node`, `clawhub`, `openclaw`
- Depends on: installed `clawsec-suite`
- Side effects: none on other skills; this package does not rewrite installed suite files
- Advisory-hook wiring is optional and manual in this release
- Network behavior: reputation checks call ClawHub inspect/search endpoints
- Trust model: scores are heuristic and confirmation-gated

## What It Does

1. Reads skill metadata from ClawHub (`inspect --json`)
2. Evaluates scanner status (including VirusTotal summary when present)
3. Applies additional reputation heuristics (age, updates, author history, downloads)
4. Requires explicit `--confirm-reputation` when score is below threshold

## Installation

Install after `clawsec-suite`:

```bash
npx clawhub@latest install clawsec-suite
npx clawhub@latest install clawsec-clawhub-checker
```

Optional preflight check (validates local paths and prints recommended command):

```bash
node ~/.openclaw/skills/clawsec-clawhub-checker/scripts/setup_reputation_hook.mjs
```

## Release Artifact Verification

For standalone installs, verify the signed release manifest before trusting `SKILL.md`, `skill.json`, or the archive. The `skill.json` file is the package metadata/SBOM source, and the release pipeline signs `checksums.json` with the ClawSec release key.

```bash
set -euo pipefail
