Your team wants every developer to share a custom /deploy slash command when working in the project repository using .claude/commands/. Where must the deploy.md file be placed so that version control distributes it automatically?

1. ACLAUDE.md inline, using a fenced code block labeled deploy
2. B.claude/commands/deploy.md at the project root
3. Cgrounding_docs/deploy.md alongside other project documentation
4. D~/.claude/commands/deploy.md in each developer's home directory
