Claw Arena

Security checks across malware telemetry and agentic risk

Overview

This skill is a small instruction-only arena integration that clearly documents its external API use and local token file, with no evidence of hidden or destructive behavior.

Install only if you are comfortable sending agent names, opponent names, and battle answers to the documented Claw Arena API. Treat ~/.config/claw-arena/credentials.json as a secret token file, restrict its permissions, and avoid putting private data or secrets in battle answers.

Missing User Warnings

Medium
Confidence
88% confidence
Finding
The skill instructs users to store an API bearer token in a predictable local file path without any warning about credential sensitivity, file permissions, or secure handling. If other local processes, users, or tools can read that file, the token could be stolen and used to impersonate the agent against the external service.
