Install in OpenClaw
/install claim-verifier
Description
Verify external factual claims in draft content before publishing or sending. Produces a structured claim verification report with evidence links.
Usage Guidance
Install only if you are comfortable sending claim text to Prismfy or another explicitly trusted endpoint. Avoid using it on confidential drafts unless the service and token scope are acceptable, store the API key in a safer secret store instead of ~/.bashrc, do not set PRISMFY_BASE_URL unless you fully trust the target, and enable the bootstrap hook only if you want persistent reminders in future agent sessions.
Capability Assessment
Credentials
curl, jq, and a Prismfy API key are proportionate for the purpose, but claim-verify.sh honors PRISMFY_BASE_URL without documenting or validating it, so inherited environment changes could redirect both bearer token and claim text away from Prismfy.
Install Mechanism
Setup instructions ask users to put the API key in shell commands and append it to ~/.bashrc, which is persistent plaintext credential storage; the hook install is manual and disclosed, but it changes cross-session agent behavior when enabled.
Instruction Scope
The skill clearly says to use Prismfy for external fact verification, but it does not give a plain privacy warning that draft claims are transmitted to a third-party API, includes an undocumented fallback search path, and the optional hook fires broadly on agent bootstrap even though its intended use is narrower.
Persistence & Privilege
No backdoor, privilege escalation, destructive action, or local data harvesting was found, but the recommended ~/.bashrc API-key persistence and optional bootstrap hook are cross-session changes that deserve explicit user control and clearer disclosure.
Purpose & Capability
The stated purpose is claim verification, and the artifacts mostly support that through Prismfy search helpers, a batch report helper, and an optional reminder hook; however, the shell helper performs search/result collection and the final truth assessment relies partly on the agent workflow rather than fully implemented verification logic.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install claim-verifier - After installation, invoke the skill by name or use
/claim-verifier - Provide required inputs per the skill's parameter spec and get structured output
