What is the purpose of YAML frontmatter in a command file?

YAML frontmatter is used to configure command metadata, such as the description shown in /help, the specific AI model to use, and the list of allowed tools like Read, Write, or Bash.

Can slash commands execute shell scripts?

Yes, slash commands support inline bash execution using the !`command` syntax, allowing you to fetch repository data or environment details to use as prompt context.

Where should I store my custom Claude Code commands?

Project-specific commands should be stored in the .claude/commands/ directory within your project, while global personal commands belong in ~/.claude/commands/.

How do I pass variables to a custom slash command?

You can use dynamic arguments like $1, $2, or $ARGUMENTS within your command's Markdown file. Claude replaces these placeholders with the input provided when you run the command.

Acerca de

The Command Development skill provides a comprehensive framework for extending Claude Code's capabilities through custom slash commands. It empowers developers to build reusable, structured instructions using Markdown and YAML frontmatter, enabling advanced features like dynamic argument passing, contextual file referencing, and inline bash execution. By following the best practices outlined in this skill, users can transform repetitive prompts into powerful, namespaced tools that can be shared across teams or used globally to significantly enhance productivity and consistency within the Claude Code environment.

Características Principales

1 GitHub stars
YAML Frontmatter configuration for tool permissions, model selection, and help descriptions.
Dynamic argument handling using positional variables ($1, $2) and global catch-alls ($ARGUMENTS).
Structured command organization supporting both flat and namespaced directory layouts.
Contextual file referencing using the '@' syntax to inject specific file contents into prompts.
Inline bash execution to gather real-time repository state, environment variables, or git data.

Casos de Uso

Standardizing team-wide workflows like PR generation, testing, and deployment through project-relative commands.
Developing interactive utilities that prompt for user input or utilize CLI tool outputs for context-aware coding.
Automating code reviews by creating commands that target specific file patterns and security standards.
