According to @bcherny, developers can create custom agents in Claude Code by adding .md files to .claude/agents, enabling per-agent names, colors, tool sets, pre-allowed or pre-disallowed tools, permission modes, and model selection; developers can also set a default agent via the agent field in settings.json or the --agent flag, as reported by the tweet and Claude Code docs. According to code.claude.com, running /agents provides an entry point to manage sub-agents and learn more about capabilities, which streamlines workflow routing and role specialization for coding tasks. According to the Claude Code documentation, this supports enterprise use cases like policy-constrained code changes, safer tool invocation, and faster task handoffs within developer teams.
