The method involves creating four Markdown definition files in a `.claude/agents/` folder, each specifying the subagent’s name, description, tools, and model. The author tested this workflow to build a Breakout-style game, where the Planner broke down requirements into specifications, the Implementer wrote the code, the Reviewer caught logic errors (like a bug where a ball passed through blocks due to double bounce logic), and the Tester verified edge cases and acceptance criteria. The process took about 10 minutes, with the human Product Owner only providing initial requirements and final approval. The author recommends starting with just one subagent (e.g., a reviewer) before scaling up, emphasizing that humans retain control over direction and acceptance decisions. The method leverages Claude Code’s subagent feature, which operates with independent context, to mimic human development team workflows more effectively than single-agent prompts.","keyPoints":["Four subagents (Planner, Implementer, Reviewer, Tester) handle distinct development tasks with separate context windows","Definition files define roles, tools, and models; the author used Opus for planning/review and Sonnet for implementation/testing","Bugs like double bounce logic were caught by the Reviewer, while the Tester validated edge cases in ~10 minutes"],"whyItMatters":"This workflow reduces human oversight time and improves code quality by separating tasks, but requires clear acceptance criteria and iterative review. It’s most useful for small projects or prototyping, where humans can still guide direction.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["Claude"],"models":["opus","sonnet"],"people":[]},"firstPublishedAt":"2026-11-03T16:12:00Z","updatedAt":"2026-11-03T16:12:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"How to Use Claude Code Subagents!
