Agent coordination YesSource
Scheduled tasks YesSource
Event triggers Partial
A person can message or start agents from chat bridges such as Telegram and Discord. The GitHub webhook handler only processes app installation events, and no trigger on issues or pull requests was found in docs or code.

Research notes

README disclaimer: not an officially supported Google product. Evolving rapidly; APIs may change. Hosted hub means your own VM, Cloud Run or Kubernetes, not a Google-run service, so deployment excludes cloud. Doc inconsistency: harnesses/README.md says default harnesses are claude and gemini, supported-harnesses.md says antigravity and gemini-cli; Codex and OpenCode are opt-in bundles either way. Agents run in containers with attachable tmux sessions. No screenshots collected.
