## Description

Picoclaw-only local posture-review skill focused on read-only findings and safe operator remediation guidance.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Picoclaw Posture Review (separate package)

Purpose: keep Picoclaw posture-review checks isolated from the broader guardian package so moderation-sensitive checks can be versioned/published independently.

## Vercel Skills Installation

Install with the Vercel Skills CLI for this harness:

```bash
npx skills add prompt-security/clawsec --skill picoclaw-self-pen-testing -a openclaw -y
```

## 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
