Dynamic Content

Bash execution (prefix with exclamation mark):

Current branch: EXCLAMATION`git branch --show-current`
Recent commits: EXCLAMATION`git log --oneline -5`

Replace EXCLAMATION with the exclamation mark character - workaround for bug #12762.

File references (prefix with at-sign):

Review the implementation in @src/utils/helpers.js

Namespacing

Subdirectories group related commands:

• .claude/commands/frontend/test.md → /test shows (project:frontend)
• .claude/commands/backend/test.md → /test shows (project:backend)

Checklist

• Description filled in frontmatter
• argument-hint if command takes arguments
• allowed-tools if using Bash or specific tools
• Test with /command-name --help style invocation
