Extraction: Extract archive
Prerequisites: OpenClaw
Primary doc: SKILL.md

Package facts

Validation

Use the Yavira download entry.
Review SKILL.md after the package is downloaded.
Confirm the extracted package contains the expected setup assets.

Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

Download the package from Yavira.
Extract it into a folder your agent can access.
Paste one of the prompts below and point your agent at the extracted folder.

New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

OpenClaw Sentinel

Supply chain security scanner for agent skills. Detects obfuscated code, known-bad signatures, suspicious install behaviors, dependency confusion, and metadata inconsistencies — before and after installation.

The Problem

You install skills from the community. Any skill can contain obfuscated payloads, post-install hooks that execute arbitrary code, or supply chain attacks that modify other skills in your workspace. Existing tools verify file integrity after the fact — nothing inspects skills for supply chain risks before they run.

Scan Installed Skills

Deep scan of all installed skills for supply chain risks. Checks file hashes against a local threat database, detects obfuscated code patterns, suspicious install behaviors, dependency confusion, and metadata inconsistencies. Generates a risk score (0-100) per skill. python3 {baseDir}/scripts/sentinel.py scan --workspace /path/to/workspace

Scan a Single Skill

python3 {baseDir}/scripts/sentinel.py scan openclaw-warden --workspace /path/to/workspace

Pre-Install Inspection

Scan a skill directory BEFORE copying it to your workspace. Outputs a SAFE/REVIEW/REJECT recommendation and shows exactly what binaries, network calls, and file operations the skill will perform. python3 {baseDir}/scripts/sentinel.py inspect /path/to/skill-directory

Manage Threat Database

View current threat database statistics. python3 {baseDir}/scripts/sentinel.py threats --workspace /path/to/workspace Import a community-shared threat list. python3 {baseDir}/scripts/sentinel.py threats --update-from threats.json --workspace /path/to/workspace

Quick Status

Summary of installed skills, scan history, and risk score overview. python3 {baseDir}/scripts/sentinel.py status --workspace /path/to/workspace

Workspace Auto-Detection

If --workspace is omitted, the script tries: OPENCLAW_WORKSPACE environment variable Current directory (if AGENTS.md exists) ~/.openclaw/workspace (default)

Threat Database Format

Community-shared threat lists use this JSON format: { "hashes": { "<sha256hex>": {"name": "...", "severity": "...", "description": "..."} }, "patterns": [ {"name": "...", "regex": "...", "severity": "..."} ] }

Exit Codes

0 — Clean, no issues 1 — Review needed 2 — Threats detected

No External Dependencies

Python standard library only. No pip install. No network calls. Everything runs locally.

Cross-Platform

Works with OpenClaw, Claude Code, Cursor, and any tool using the Agent Skills specification.

Category context

Workflow acceleration for inboxes, docs, calendars, planning, and execution loops.
