Custom Slash Command Creator

Overview

Claude Code slash commands are markdown files with optional YAML frontmatter that create reusable /command workflows. Commands and skills are unified: .claude/commands/ files and .claude/skills/ directories both create slash commands. Skills are the recommended approach since they support additional features like supporting files, but single-file commands still work.

When to use: Repeatable prompts, team workflow standardization, guardrailed operations (deploy, commit), multi-phase tasks, dynamic context injection with bash output.

When NOT to use: Complex capabilities needing multiple files and scripts (use a full skill directory instead), one-off prompts, built-in commands that already exist (/compact, /help, /init).

Quick Reference

Feature Syntax / Location Key Points
Project command .claude/commands/name.md Shows "(project)" in /help
Project skill .claude/skills/name/SKILL.md Recommended over commands, supports extra files
Personal command ~/.claude/commands/name.md Available across all projects
Personal skill ~/.claude/skills/name/SKILL.md Available across all projects
Plugin command <plugin>/skills/name/SKILL.md Namespaced as plugin-name:skill-name
Subdirectory commands .claude/commands/git/commit.md Shows "(project:git)" in /help
All arguments $ARGUMENTS Entire argument string
Positional arguments $0, $1, $2 or $ARGUMENTS[0] Zero-based index
Bash injection ` !git status ` Runs before prompt is sent, output replaces placeholder
File reference @src/file.ts Inlines file contents into prompt
Extended thinking Include "ultrathink" in content Triggers deeper reasoning mode
Session ID ${CLAUDESESSIONID} Current session identifier for logging
Frontmatter description description: What it does Required for /help listing and Skill tool
Tool restrictions allowed-tools: Read, Grep, Glob Limits tools without per-use approval
Manual-only invocation disable-model-invocation: true Prevents Claude from auto-triggering
Hide from menu user-invocable: false Background knowledge only Claude loads
Argument hint argument-hint: [issue-number] Shown in autocomplete
Model override model: claude-sonnet-4-20250514 Specific model for this command
Subagent execution context: fork Runs in isolated context
Subagent type agent: Explore Built-in or custom agent when context: fork

Priority Order

When commands share the same name across levels, higher-priority locations win:

  1. Enterprise (managed settings)
  2. Personal (~/.claude/)
  3. Project (.claude/)

Plugin commands use namespacing (plugin:name) so they never conflict. If a skill and a command share the same name, the skill takes precedence.

Common Mistakes

Mistake Impact Correct Pattern
Adding name field in command files Ignored for .md commands Name is inferred from filename
Missing description frontmatter Invisible in /help and Skill tool Always include description
Using category or tags fields Silently ignored Use subdirectories for organization
$ARGUMENTS without handling empty case Unexpected behavior Check if empty and provide default
` !bash without allowed-tools` Commands fail to execute Add allowed-tools: Bash(...) to frontmatter
Expecting project to override personal Personal wins over project Personal commands take priority; rename to avoid conflicts
Using context: fork without a task Subagent has no actionable work Only fork skills with explicit step-by-step instructions
Overriding built-in command names Built-ins cannot be overridden Use different names (/my-help not /help)

Delegation

  • Command pattern discovery: Use Explore agent to find existing commands in .claude/commands/ or .claude/skills/
  • Complex workflow skills: For multi-file capabilities, create a full skill directory with SKILL.md and supporting files
