Usage Guidance
This skill is low-risk: it only makes simple HTTP GET requests to catfact.ninja and doesn't ask for credentials or install code. Before installing, note that the SKILL.md expects curl (and shows optional jq usage) even though the registry lists no required binaries — ensure your environment permits outbound HTTP requests and has curl (or use an alternative HTTP client). If you have strict egress controls, verify network access to catfact.ninja. Otherwise it's safe to use for fun bot responses.
Capability Analysis
Type: OpenClaw Skill
Name: catfact
Version: 1.0.2
The skill bundle is benign. It provides instructions and examples for fetching cat facts and breed information from the `catfact.ninja` API using `curl` and `jq`. All commands in `SKILL.md` are standard HTTP GET requests to the documented public API, with no evidence of data exfiltration, malicious execution, persistence mechanisms, or prompt injection attempts to subvert the agent's behavior. The required `curl` binary and optional `jq` for JSON parsing are appropriate for the stated purpose.
Capability Assessment
Purpose & Capability
The skill's description (random cat facts / breeds from catfact.ninja) matches the runtime instructions. Minor inconsistency: SKILL.md metadata lists a required binary (curl) while the registry's required-binaries section is empty.
Instruction Scope
Instructions are limited to issuing HTTP GET requests to catfact.ninja (and optional local JSON parsing with jq). They do not reference unrelated files, credentials, or external endpoints beyond the stated API.
Install Mechanism
No install spec or code is provided (instruction-only), so nothing is downloaded or written to disk.
Credentials
The skill requires no environment variables or credentials. Example usage mentions jq for parsing (not declared in metadata) but that is optional for convenience.
Persistence & Privilege
always is false and the skill does not request persistent or elevated privileges. Autonomous invocation is allowed by default but is not combined with any broad credential or install requirements.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install catfact - After installation, invoke the skill by name or use
/catfact - Provide required inputs per the skill's parameter spec and get structured output
