I did not expect Claude Code to release Custom Sub Agents

The video showcases Claude Code’s new custom sub agents feature, allowing users to create specialized agents with distinct contexts to improve coding workflows, demonstrated through modes like pair programmer and backend developer. Despite some limitations, the creator highlights the potential for enhanced automation and collaboration in development processes, encouraging viewers to explore and contribute ideas for further refinement.

The video begins by addressing recent challenges faced by Claude Code, including API outages and inconsistent performance, especially with more complex coding tasks. The creator acknowledges these issues but shifts focus to an exciting new discovery: the introduction of custom sub agents via a slash command. This feature allows users to create specialized agents with their own context windows, potentially improving efficiency and reducing costs compared to previous orchestration methods like boomerang mode.

The presenter shares their initial experiments with custom sub agents, highlighting a “pair programmer” mode designed to offer multiple coding options rather than jumping straight into implementation. Although still a work in progress, this mode successfully generated different approaches for a simple task like making a page mobile responsive, followed by a code review phase. Despite some rate limits and minor flaws, the workflow demonstrated promising results and smoother task execution compared to earlier experiences.

Next, the video explores a more complex task involving code refactoring, where the sub agents provided multiple approaches and allowed the user to select one for implementation. The presenter also explains how to create new sub agents by adding markdown files in a commands folder, emphasizing the flexibility to customize agents for specific roles, such as a backend developer. They demonstrate creating an expert backend developer agent tailored to best practices and specific coding standards, showcasing the ease of generating and editing these agents.

Further, the creator discusses integrating additional tools and workflows, such as a new LLM tool called Railon help, which can handle queries and provide context-aware responses. They illustrate a multi-agent workflow starting with the pair programmer, moving to the backend architect, and concluding with a code reviewer. While some coordination issues remain, such as confirmation steps and context sharing between agents, the overall system shows great potential for automating and refining development processes.

In conclusion, the video expresses enthusiasm for the possibilities unlocked by custom sub agents and workflows, envisioning a future where tedious tasks are handled by highly specialized agents. The presenter invites viewers to share ideas for new sub agents and highlights the importance of ongoing refinement to achieve consistent, effective results. They encourage engagement with the video and express optimism about the evolving capabilities of Claude Code’s platform.
