Skills Security Audit

1. Why Skills Security Matters

Skills are plugins that extend your OpenClaw agent with new tools-browser control, email, calendar, custom APIs, and more. They run in your environment and can access credentials, the filesystem, and the network. A vulnerable or malicious skill can:

• Leak API keys and secrets - Through logging, error messages, or external calls (e.g. to an attacker’s server).
• Execute unintended commands - If the skill is buggy or hostile, it may run shell commands or tools you did not authorize.
• Introduce vulnerable dependencies - Outdated or compromised npm packages used by the skill.

Security researchers (including Cisco, CrowdStrike, and Snyk) have highlighted risks around the OpenClaw gateway and the skills marketplace. Snyk reported that approximately 7.1% of analyzed ClawHub skills could leak credentials-for example by logging secrets, embedding them in error messages, or sending them to external endpoints. Media and industry reports have also documented malware and fake crypto tools in the marketplace. Auditing skills before and after installation is essential for personal, business, and enterprise use.

2. Before Installing a Skill

Review source and publisher

• Prefer skills from known publishers or with visible source code (e.g. GitHub links) so you or the community can review behavior.
• Check download counts, ratings, and recent updates-but do not rely on popularity alone; malicious skills can gain traction.
• Read the skill’s description and required permissions; avoid skills that request more access than needed for the stated feature.

Pin versions

Install a specific version of a skill (e.g. openclaw skills install skill-name@1.2.0) so that automatic or accidental updates do not pull in malicious or broken changes. Pin versions in your configuration and review release notes before upgrading. See Installing Skills for the exact CLI syntax.

Use a test environment when possible

If you have a staging or test OpenClaw instance, install and exercise new skills there first. Monitor logs for unexpected network calls or file access before rolling out to production.

3. Running the Security Audit

When your OpenClaw version supports it, run the built-in security audit to scan installed skills and configuration for known issues, credential exposure, and policy violations:

When to run it:

• After every new skill install.
• After updating any skill (or run it regularly if you use update --all).
• On a regular schedule (e.g. monthly) as part of your security hygiene.

Fix any reported issues (e.g. move secrets to environment variables, restrict permissions, or remove a risky skill). For a full checklist, see Security Checklist and OpenClaw Skills Security.

4. Signs of Malicious or Vulnerable Skills

Watch for these red flags that a skill may be malicious or unsafe:

• Unexpected network calls - Skills that contact unknown or external IPs/domains, especially with sensitive data.
• Broad file or filesystem access - Reading or writing outside the documented scope (e.g. config files, SSH keys, credential stores).
• Credential usage that doesn’t match the feature - A “weather” skill that requests full API key scope.
• Obfuscated or minified code - Hard-to-review code increases the risk of hidden behavior.
• Fake or misleading descriptions - Promises of “free crypto” or “guaranteed returns” often accompany scam skills; reports have cited fake crypto tools in the marketplace.
• No visible source or unmaintained repo - No way to verify behavior or get security fixes.

Enable audit logging and monitoring so you can spot unusual tool use or outbound connections. If you suspect a skill, disable it immediately, rotate any exposed credentials, and check Known Vulnerabilities and official advisories.

5. Credential Leak Prevention

To reduce the impact of credential leaks from skills:

• Store secrets in environment variables or a secrets manager - Not in config files that skills might read. See Credential Management.
• Limit which credentials skills can access - Only pass the minimum required; avoid giving skills broad API keys or root access.
• Set API spending limits - So that a compromised or buggy skill cannot burn through your LLM or third-party API budget.
• Run openclaw security audit regularly - To catch misconfigurations and known bad patterns.

6. Safe Installation and Update Workflow

1. Read the skill’s docs and required permissions; confirm the publisher or source when possible.
2. Install in a test environment first if you have one.
3. Pin the skill version in your config (e.g. skill-name@1.2.0).
4. Run openclaw security audit after installation.
5. Monitor logs for the first few days for unexpected network calls or errors.
6. When updating, review release notes and run the audit again; rotate credentials if the skill had access and an update addressed a security issue.

8. Security Checklist for Skills

Use this list alongside the main Security Checklist:

• ☐ Only install skills from sources you’ve reviewed (publisher, repo, or docs).
• ☐ Pin skill versions in configuration.
• ☐ Run openclaw security audit after each new skill install and on a regular schedule (e.g. monthly).
• ☐ Store credentials in environment variables or a secrets manager; avoid putting secrets in config that skills can read.
• ☐ Set API spending limits where possible.
• ☐ Monitor logs for unexpected network calls, file access, or credential use.
• ☐ Bookmark Known Vulnerabilities and official security advisories for CVE and ClawHub incident updates.
