Where are the created agents stored?

Agents are stored as Markdown files in ~/.claude/agents/ for global (user-level) access or within a project's .claude/agents/ directory for repo-specific behavior.

Does this skill follow Opus 4.5 prompting best practices?

Yes, it includes specific guidelines for Opus 4.5, such as using imperative language, avoiding aggressive keywords, and including anti-over-engineering guidance.

What is the difference between an Agent and a Skill in Claude Code?

An Agent changes who Claude is (persona, tools, model), while a Skill changes what Claude knows (knowledge, procedures, scripts). Agents can load skills, but skills cannot become agents.

Can I restrict which tools an agent can use?

Yes, the Agent Creator allows you to define a whitelist of tools in the YAML frontmatter, preventing the agent from using unauthorized capabilities like Bash or Write.

Why should I use the Haiku model for some agents?

Haiku is recommended for simple, repetitive tasks like quick searching or basic data extraction to optimize for speed and significantly reduce token costs.

Productivity & Workflow

Streamlines the creation and configuration of specialized Claude Code agents with custom personas, tool restrictions, and model selections.

The Agent Creator skill provides a comprehensive framework for building and optimizing Claude Code agents, which are specialized personas that fundamentally change Claude's behavior for specific tasks. It guides users through the entire lifecycle of agent development—from defining tool whitelists and model selection (Haiku, Sonnet, or Opus) to crafting high-performance system prompts using Opus 4.5 best practices. This skill is essential for developers looking to automate repetitive workflows, restrict tool usage for security, or create domain-specific orchestrators that can delegate tasks to sub-agents.
