Create and refine OpenCode agents via guided Q&A. Use when creating an agent file, improving an existing agent, configuring AGENTS.md frontmatter, setting subagent_type, defining allowed-tools, restricting permissions, designing agent routing, writing a system prompt, configuring mode: subagent, setting a permission block, or working with the Task tool delegation pattern. Examples: 'Create an agent for code reviews', 'My agent ignores context', 'Add a database expert subagent', 'Make my agent faster', 'Agent triggers on wrong requests'.
