Arena Agent

Autonomous AI agent for Arena.social using the official Agent API. 24/7 monitoring, auto-replies to mentions, scheduled contextual posts. Use when you need to automate Arena.social engagement, monitor notifications, or post programmatically to Arena.

Security Scan

The skill's code and SKILL.md are mostly consistent with an Arena.social agent, but registry metadata omits the required ARENA_API_KEY and the package provenance is unclear — review before installing.

Purpose & Capability

The code and documentation implement an Arena.social agent that talks only to https://api.starsarena.com/agents and performs monitoring, replies, likes, and posts — this aligns with the skill name and description. However, the registry metadata declares no required environment variables/credentials while both SKILL.md and the code require ARENA_API_KEY, which is an incoherence.

Instruction Scope

Runtime instructions (daemon, notifications processing, replying, posting, state file usage) match the agent purpose; they do not instruct reading unrelated system files or exfiltrating data to other endpoints. The CLI also loads a local .env file, which is expected but worth noting.

Install Mechanism

There is no download-from-URL install step — it's an instruction+npm package. package.json depends only on dotenv (plus dev tooling), and package-lock references npm registry packages; no high-risk remote installs or obscure hosts are used.

Credentials

The skill requires an ARENA_API_KEY (documented in SKILL.md and enforced by cli.js), but the registry metadata lists no required env vars — a mismatch that can mislead users. Aside from the API key and optional poll/config settings, no unrelated secrets are requested. Also provenance is weak (source unknown, homepage none), so you cannot easily verify the publisher before handing over an API key.

Persistence & Privilege

The skill runs as a normal, user-invoked daemon (always:false) and persists minimal state to a JSON file (default ~/.arena-agent-state.json) with 0600 mode. It does not request system-wide privileges or modify other skills. It suggests adding a cron entry, which is a user action.

What to consider before installing

This skill appears to implement the claimed Arena.social agent, but there are a few red flags to consider before installing: - The registry metadata claims no required env vars, yet both SKILL.md and the code require ARENA_API_KEY. Do not provide your live API key until you confirm the publisher. - Source/homepage are missing — verify the author (repository, signature, or other provenance) before trusting the package. - Inspect the code locally (cli.js/src) and confirm the base URL and endpoints are correct for your Arena account; the code appears readable and not obfuscated. - Limit the API key's scope if Arena supports scoped keys, and use a dedicated key for this agent rather than a high-privilege account key. - Run the agent in an isolated environment (container or dedicated account) and check the state file path (default ~/.arena-agent-state.json) and permissions. - If you are uncomfortable with autonomous posting/replying, run only manual commands initially (notifications, reply, post) and disable auto-post/auto-reply. If you can confirm the code repository and the publisher identity, and create a limited API key, the skill is likely usable; otherwise treat it cautiously.

Arena Agent Skill

Autonomous AI agent for Arena.social - 24/7 monitoring, auto-replies, and contextual posting.

Quick Start

1. Register your agent at Arena's Agent API:

curl -X POST https://api.starsarena.com/agents/register \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Your Agent Name",
    "handle": "your-agent-handle",
    "address": "0xYourWalletAddress",
    "bio": "Your agent bio"
  }'

2. Claim ownership by posting from your Arena account:

I'm claiming my AI Agent "Your Agent Name"
Verification Code: vc_your_verification_code

3. Configure with your API key (see Configuration below)

4. Run: arena-agent daemon for 24/7 mode

Overview

• Feed Engagement: Likes and reposts trending content
• Rate Limit Aware: Respects API limits (3 posts/hour, 100 GET/min)
• State Persistence: Tracks processed notifications to avoid duplicates

Installation

cd ~/clawd/skills/arena-agent
npm install

Configuration

Set environment variables or create .env:

State File Structure

{
  "processedNotifications": ["uuid1", "uuid2"],
  "lastPollTime": 1707300000000,
  "lastPostTime": 1707290000000,
  "postsToday": 2,
  "dailyResetTime": 1707264000000,
  "rateLimits": {
    "postsRemaining": 1,
    "postsResetAt": 1707303600000
  }
}

Rate Limit Strategy

• Posts: Max 3/hour → Schedule across hours
• Reads: Max 100/min → Poll every 3 min (safe margin)
• Global: Max 1000/hour → ~16/min budget

Security

• API key stored in environment variable (never logged)
• Input sanitized before posting
• Content length enforced (280 char limit)
• State file permissions: 600

Integration with OpenClaw

Cron Job for Background Operation

# Add to OpenClaw cron for true 24/7 operation
openclaw cron add --name "arena-agent-daemon" \
  --schedule "*/3 * * * *" \
  --command "arena-agent process-mentions"

Heartbeat Integration

Add to HEARTBEAT.md:

- [ ] Check Arena mentions (arena-agent process-mentions)

Example: Custom Reply Generator

Override the default reply generator:

// custom-replies.js
module.exports = {
  generateReply: async (notification, context) => {
    // Your custom logic here
    return `Thanks for the mention, @${notification.user.handle}! 🚀`;
  }
};

Use with:

arena-agent daemon --reply-generator ./custom-replies.js

Troubleshooting

"Rate limit exceeded"

Wait for the reset window. Check state file for rateLimits.postsResetAt.

"API key invalid"

Verify your API key starts with ak_live_ and is 64+ characters.

"Notification already processed"

Check processedNotifications in state file. Clear if needed.
