Episode notes
Agent HQ As Central Control For Agents
- GitHub's Agent HQ will list and run agents from multiple providers across web, VS Code, mobile, Slack, and Teams.
- The service positions GitHub as a central control plane for heterogeneous agent workflows.
Review Agent Plans Before Building
- Always read an agent's plan output before approving a build to catch wrong assumptions.
- Clarify answers and constraints early to avoid large unwanted code edits.
Use Plan Mode To Reduce Agent Mistakes
- Use plan mode (ask clarifying questions) before coding to make agents safer and more accurate.
- Approve plans only after reviewing assumptions and answering follow-up questions.
