@yangyi showcases how Lead Signal Listener was built end-to-end in a single NewMax agent conversation — including the promo video.
- Starts from "can we build a lead-listening service?" to a local app on the treg.to API: real data, UI rework, bilingual interface, an agent setup guide, then open-sourced on GitHub
- 29 human requests / 55 messages, 10+ built-in sources plus RSS and any Treg API
- First real run: $0.073 for 284 leads
- The full (redacted) conversation log is published on the showcase page
A complete first-hand case of shipping a usable open-source product in one conversation.
