Can I share styles with my team?

Yes, by storing style files in the .claude/output-styles/ directory within your repository, they become available to everyone working on that project.

Does changing the output style remove Claude's coding tools?

No, output styles only replace the system prompt personality; all core tools like Bash, Read, Write, and MCP integrations are fully preserved.

What is the keep-coding-instructions field used for?

When set to true in the style frontmatter, it ensures that the original coding-specific instructions from the default prompt are retained even if the rest of the persona is replaced.

How does this differ from the instructions in CLAUDE.md?

CLAUDE.md adds project-specific context as a user message, whereas Output Styles replace the foundational system prompt that defines Claude's core personality and interaction rules.

How do I switch between different output styles?

You can use the /output-style command followed by the style name or simply type /output-style to browse a menu of available styles.
