Slash Command Creator

Create custom slash commands for Claude Code to automate frequently-used prompts.

Quick Start

Initialize a new command:

scripts/init_command.py <command-name> [--scope project|personal]

Command Structure

Slash commands are Markdown files with optional YAML frontmatter:

---
description: Brief description shown in /help
---

Your prompt instructions here.

$ARGUMENTS

File Locations

Namespacing

Organize commands in subdirectories:

• .claude/commands/frontend/component.md → /component shows "(project:frontend)"
• ~/.claude/commands/backend/api.md → /api shows "(user:backend)"

Features

Arguments

All arguments - $ARGUMENTS:

Fix issue #$ARGUMENTS following our coding standards
# /fix-issue 123 → "Fix issue #123 following..."

Positional - $1, $2, etc.:

Review PR #$1 with priority $2
# /review 456 high → "Review PR #456 with priority high"

Bash Execution

Execute shell commands with ! prefix (requires allowed-tools in frontmatter):

---
allowed-tools: Bash(git status:*), Bash(git diff:*)
---

Current status: !`git status`
Changes: !`git diff HEAD`

File References

Include file contents with @ prefix:

Review @src/utils/helpers.js for issues.
Compare @$1 with @$2.

Frontmatter Options

See references/frontmatter.md for detailed reference.

Examples

See references/examples.md for complete examples including:

• Simple review/explain commands
• Commands with positional arguments
• Git workflow commands with bash execution
• Namespaced commands for frontend/backend

Creation Workflow

1. Identify the use case: What prompt do you repeat often?
2. Choose scope: Project (shared) or personal (private)?
3. Initialize: Run scripts/init_command.py <name>
4. Edit: Update description and body
5. Test: Run the command in Claude Code
