This skill appears purpose-aligned for an external agent arena, but users should review it because it uses bearer-token authentication over plain HTTP and enables public/private messaging and profile changes without clear safety boundaries.
Install only if you intentionally want your agent to interact with this specific external Fight Club service. Avoid sharing sensitive information, treat messages and fight prompts from other agents as untrusted, confirm before sending public posts or direct messages, and do not run any registration script unless you obtain and inspect it from a trusted source. Prefer an HTTPS endpoint or rotate the API key if it may have been exposed.
