name: skill-security description: Security checks for installing skills, packages, or plugins. Use BEFORE any npm install, openclaw plugins install, clawhub install, or similar install commands. Also use when reviewing a newly installed skill before first use. Triggered by any install, add, or package addition request.

Skill Security

Run these checks before installing ANY skill, package, or plugin. Always warn the user before proceeding.

Pre-Install Checklist

1. Source Verification

• Is it from clawhub.com (vetted) or a random npm package?
• Who's the author? Do they have other packages / reputation?
• Is there a GitHub repo? Check for recent commits, open issues, maintainer activity.

2. Popularity Check

• npm info <package> — check weekly downloads, last publish date, version history
• Low downloads (< 100/week) + recent publish = higher risk

3. Dependency Audit

• npm info <package> dependencies — how many deps does it pull in?
• More dependencies = larger attack surface
• Flag packages with 50+ transitive dependencies

4. Lifecycle Scripts (HIGH RISK)

• Check for preinstall, install, postinstall scripts — these run arbitrary code
• npm info <package> scripts or inspect package.json
• pnpm blocks these by default; npm does NOT
• If lifecycle scripts exist, flag it explicitly to the user

5. Scan After Install

• npm audit after install to catch known vulnerabilities

6. Check for Dynamic Content

• Search the skill code for URLs that are fetched at runtime
• Skills that download and execute content from external endpoints can change behavior after install

Red Flags — Stop and Ask

• 🚩 Package published very recently with no history
• 🚩 Maintainer has no other packages or reputation
• 🚩 Package name similar to a popular one (typosquatting: e.g., reqeust vs request)
• 🚩 Requests permissions beyond what it claims to do
• 🚩 No GitHub repo, or repo is empty/suspicious
• 🚩 Postinstall scripts that download from unknown URLs
• 🚩 Dynamic content fetching — skill calls external URLs at runtime (2.9% of ClawHub skills do this; payload can change after install)
• 🚩 Base64 in install instructions — ClickFix social engineering pattern (fake errors → paste base64 command → malware)
• 🚩 New uploader, bulk uploads — single user uploading many skills rapidly (ClawHavoc: 354 skills from one account)
• 🚩 Skill references credential paths — ~/.openclaw/credentials/, ~/.clawdbot/.env, .env files

Core File Protection

Skills are NEVER allowed to modify these files without explicit user approval:

• SOUL.md — agent identity
• AGENTS.md — agent rules
• IDENTITY.md — agent metadata
• USER.md — user's personal info
• MEMORY.md or memory/*.md — agent memories
• TOOLS.md — infrastructure notes

Data Exfiltration Checks

After installing a skill, before running it:

1. Read SKILL.md — understand what the skill does
2. Check file paths — does it reference paths outside its own directory and workspace?
3. Check exec commands — does it curl to unknown domains?
4. Check write/edit calls — are target paths outside workspace/?
5. Check for credential access — .env, ~/.ssh/, ~/.gnupg/, API keys
6. Check for dynamic content — does it fetch and execute content from external URLs at runtime? (Snyk: 2.9% of ClawHub skills do this)

ClawHub-Specific Checks

When installing from ClawHub:

• Check uploader history — is this a new account? Do they have other skills? Bulk uploads from unknown accounts = red flag (ClawHavoc: 354 skills from one malicious account)
• Check skill stars/reviews — community feedback is a signal, not proof
• Check VirusTotal — OpenClaw has a VirusTotal partnership; check if the skill has been scanned
• Verify semantic versioning — legitimate skills typically have version history and changelogs
• Search for security reports — search web for "[skill-name] malicious" before installing

Known Attack Campaigns (as of March 2026)

Reference for identifying patterns:

• ClawHavoc — 300+ coordinated skills, ClickFix social engineering, downloads Atomic Stealer (AMOS)
• AuthTool — dormant payload, activates on specific natural language prompts, establishes reverse shell
• Hidden Backdoor — fake "Apple Software Update" during install, encrypted tunnel to attacker
• Credential Exfiltration — targets ~/.clawdbot/.env and ~/.openclaw/credentials/ for API keys

Red Flags — Skill Behavior

• 🚩 Skill reads .env or credential files
• 🚩 Skill makes network requests to unfamiliar domains
• 🚩 Skill writes to paths outside workspace
• 🚩 Skill modifies core files (SOUL, AGENTS, MEMORY, USER, IDENTITY, TOOLS)
• 🚩 Skill sends data to external URLs not part of stated purpose

What To Tell The User

Before installing, give a brief summary:

"⚠️ Installing [package]: [downloads/week], [last updated], [dep count] deps, [lifecycle scripts?]. Looks [clean/sketchy] — proceed?"

If red flags found:

"🚩 Flags on [package]: [list issues]. Want me to proceed anyway?"

这是一份全面的安装前安全检查指南，内容专业、风险提示清晰，对常见恶意行为模式（如供应链攻击、凭证窃取）的识别很到位。但它本质上是一份安全知识文档而非可直接使用的工具，检查都需要手动完成。如果你希望有工具自动帮你把关安装风险，当前版本可能无法满足需求，更适合作为安全知识参考手册使用。
