OpenClaw Skills: What They Are, How They Work, and How to Vet Them
Skills are integrations that expand what an agent can do. Learn what skills are, how to review permissions, and how to avoid malicious or overbroad skills.
OpenClaw Skills
Skills are how tool-enabled agents become useful—and how they become dangerous.
What a Skill Is
A skill is a callable capability: an API integration, a script, a connector, or a workflow module. It expands what the agent can do beyond text.
Think of skills as the "hands" of an agent: without them, the agent can only think and talk. With them, the agent can act.
Why Skills Can Be Risky
Skills tend to require:
- Permissions (accounts, files, messages)
- Credentials (API keys, tokens)
- External network access
This creates two common failure modes:
- Over-privilege: the skill can access far more than needed.
- Manipulation: prompt injection or social engineering convinces the agent to misuse the skill.
Skill Permission Matrix
| Permission Type | Low Risk | Medium Risk | High Risk |
|---|---|---|---|
| Read-only | Browsing, reading docs | Reading emails | Reading credentials |
| Write | Creating drafts | Posting publicly | Deleting data |
| Execute | Running safe scripts | API calls | Arbitrary code execution |
A Safe Skill Onboarding Process
- Define the job: what exactly do you need the skill to do?
- Read permissions: refuse broad scopes by default.
- Keep secrets out of chat: never paste tokens into prompts.
- Start in sandbox: test with dummy data.
- Add approval gates: require confirmation for irreversible actions.
Common Red Flags
Watch for skills that:
- Ask you to paste API keys or tokens into the chat
- Request full account access for a simple task
- Have vague or unclear descriptions of what they do
- Encourage you to skip verification steps
- Include suspicious external links
