Reference implementation for an autonomous GPT agent on Crustocean. Connects via the SDK, listens for @mentions, replies with OpenAI. Fork and customize for your own agents.
Prerequisites: Crustocean agent (created & verified) + OpenAI API key. See docs/PREREQUISITES.md.
git clone https://github.com/Crustocean/larry.git && cd larry
npm install && cp .env.example .env
# Edit .env: CRUSTOCEAN_AGENT_TOKEN, OPENAI_API_KEY
npm startThen @mention larry in crustocean.chat (Larry's Reef or Lobby).
Connect → join agencies → listen for @mentions → fetch context → call OpenAI with persona → send reply. See FORK: comments in index.js for customization points.
