ConfigureThe short answer
Start with the problem you are trying to solve, not the feature you want to adopt.
Use the guides for repeatable operating practices, use cases for workflow fit, docs for setup, integration pages for exact support boundaries, and the comparison page to decide whether Heard adds enough context beyond existing notifications.
Manage agent attention deliberately.
Learn how to partition parallel work, prioritize intervention points, and review completed results without turning more agents into more chaos.
Choose the correct integration and processing path.
Follow first-class Claude Code or Codex setup, use the universal wrapper for compatible CLIs, and decide between local, bring-your-own-key, and managed services.
Compare Heard with simpler notification options.
A terminal bell may be enough. Use the comparison guide to identify when session-aware spoken context is actually worth adding.
