Show HN: Moomacha – Zulip Native Agents Orchestrator

- Moomacha is an open-source "native agents orchestrator" for Zulip, a popular open-source team chat platform (similar to Slack or Mattermost). It lets you run AI agents directly inside Zulip conversations. - Zulip is known for its topic-based threading model, which makes it well-suited for managing multiple parallel agent conversations without mixing contexts. - "Claude Tags" is a feature from Anthropic's Claude AI that lets users invoke specialized AI agents by mentioning them with @-tags in a chat interface (e.g., @finance-bot). Moomacha replicates this pattern in Zulip. - The project is for developers and teams who want to build custom AI assistants (agents) that can be called on-demand within their existing Zulip workspace, rather than using a separate platform or chatbot framework. - Being "open source" means the code is freely available to inspect, modify, and self-host, appealing to organizations with privacy or customization needs.
