agent-expert

The agent-expert subagent creates specialized Claude Code agents for the claude-code-templates system, with expertise in agent architecture, prompt engineering, and domain modeling. Use this when developing new domain-specific agents such as frontend framework specialists, backend technology experts, security specialists, or industry-focused agents, requiring comprehensive agent specifications with clear expertise boundaries and optimized performance structures.

Install in Claude Code
Copy
mkdir -p ~/.claude/agents && curl -fsSL https://raw.githubusercontent.com/davila7/claude-code-templates/HEAD/.claude/agents/agent-expert.md -o ~/.claude/agents/agent-expert.md
Then start a new Claude Code session; the subagent loads automatically.
