Descriptions:
Craig Hewitt walks through building a fully autonomous Twitter content agent using Twin, an AI agent platform with built-in browser automation. The agent runs three times daily at scheduled intervals — 8am, 12pm, and 6pm — monitors trending topics in the AI and automation space, drafts original tweets matched to a custom brand voice document, and sends them via Telegram for creator approval before automatically posting to X.
A second parallel function monitors the creator’s existing posts for meaningful replies and engagement, filtering out noise and sending notifications only when a response genuinely warrants attention. Hewitt covers the full setup in real time: crafting a detailed upfront prompt, configuring the X developer pay-per-use API at developer.x.com, and creating a Telegram notification bot via BotFather. He notes that Twin lacks up-to-date context on X’s current API pricing model, making it necessary to manually inform the agent before it begins building — a useful heads-up for anyone attempting the same workflow.
The entire system costs an estimated five dollars per month in API fees. Hewitt emphasizes writing a comprehensive initial prompt that gives the agent the complete picture at once rather than adding requirements incrementally — a principle he argues applies across all AI agent platforms. This walkthrough is well-suited for content creators, marketers, and founders who want to automate routine social media work without losing editorial control.
