Create Slash Commands

<objective>
Create effective slash commands for Claude Code that enable users to trigger reusable prompts with `/command-name` syntax. Slash commands expand as prompts in the current conversation, allowing teams to standardize workflows and operations. This skill teaches you to structure commands with XML tags, YAML frontmatter, dynamic context loading, and intelligent argument handling.
</objective>

<quick_start>

<workflow>
1. Create `.claude/commands/` directory (project) or use `~/.claude/commands/` (personal)
2. Create `command-name.md` file
3. Add YAML frontmatter (at minimum: `description`)
4. Write command prompt
5. Test with `/command-name [args]`
</workflow>

<example>
**File**: `.claude/commands/optimize.md`

---
description: Analyze this code for performance issues and suggest optimizations
---

Analyze the performance of this code and suggest three specific optimizations:

Usage: /optimize

Claude receives the expanded prompt and analyzes the code in context. </example> </quick_start>

<xml_structure> All generated slash commands should use XML tags in the body (after YAML frontmatter) for clarity and consistency.

<required_tags>

<objective> - What the command does and why it matters

<objective>
What needs to happen and why this matters.
Context about who uses this and what it accomplishes.
</objective>

<process> or <steps> - How to execute the command

<process>
Sequential steps to accomplish the objective:
1. First step
2. Second step
3. Final step
</process>

<success_criteria> - How to know the command succeeded

<success_criteria>
Clear, measurable criteria for successful completion.
</success_criteria>

</required_tags>

<conditional_tags>

<context> - When loading dynamic state or files

<context>
Current state: ! `git status`
Relevant files: @ package.json
</context>

(Note: Remove the space after @ in actual usage)

<verification> - When producing artifacts that need checking

<verification>
Before completing, verify:
- Specific test or check to perform
- How to confirm it works
</verification>

<testing> - When running tests is part of the workflow

<testing>
Run tests: ! `npm test`
Check linting: ! `npm run lint`
</testing>

<output> - When creating/modifying specific files

<output>
Files created/modified:
- `./path/to/file.ext` - Description
</output>

</conditional_tags>

<structure_example>

---
name: example-command
description: Does something useful
argument-hint: [input]
---

<objective>
Process $ARGUMENTS to accomplish [goal].

This helps [who] achieve [outcome].
</objective>

<context>
Current state: ! `relevant command`
Files: @ relevant/files
</context>

<process>
1. Parse $ARGUMENTS
2. Execute operation
3. Verify results
</process>

<success_criteria>
- Operation completed without errors
- Output matches expected format
</success_criteria>

</structure_example>

<intelligence_rules>

Simple commands (single operation, no artifacts):

• Required: <objective>, <process>, <success_criteria>
• Example: /check-todos, /first-principles

Complex commands (multi-step, produces artifacts):

• Required: <objective>, <process>, <success_criteria>
• Add: <context> (if loading state), <verification> (if creating files), <output> (what gets created)
• Example: /commit, /create-prompt, /run-prompt

Commands with dynamic arguments:

• Use $ARGUMENTS in <objective> or <process> tags
• Include argument-hint in frontmatter
• Make it clear what the arguments are for

Commands that produce files:

• Always include <output> tag specifying what gets created
• Always include <verification> tag with checks to perform

Commands that run tests/builds:

• Include <testing> tag with specific commands
• Include pass/fail criteria in <success_criteria> </intelligence_rules> </xml_structure>

<arguments_intelligence> The skill should intelligently determine whether a slash command needs arguments.

<commands_that_need_arguments>

User provides specific input:

• /fix-issue [issue-number] - Needs issue number
• /review-pr [pr-number] - Needs PR number
• /optimize [file-path] - Needs file to optimize
• /commit [type] - Needs commit type (optional)

Pattern: Task operates on user-specified data

Include argument-hint: [description] in frontmatter and reference $ARGUMENTS in the body. </commands_that_need_arguments>

<commands_without_arguments>

Self-contained procedures:

• /check-todos - Operates on known file (TO-DOS.md)
• /first-principles - Operates on current conversation
• /whats-next - Analyzes current context

Pattern: Task operates on implicit context (current conversation, known files, project state)

Omit argument-hint and don't reference $ARGUMENTS. </commands_without_arguments>

<incorporating_arguments>

In <objective> tag:

<objective>
Fix issue #$ARGUMENTS following project conventions.

This ensures bugs are resolved systematically with proper testing.
</objective>

In <process> tag:

<process>
1. Understand issue #$ARGUMENTS from issue tracker
2. Locate relevant code
3. Implement fix
4. Add tests
</process>

In <context> tag:

<context>
Issue details: @ issues/$ARGUMENTS.md
Related files: ! `grep -r "TODO.*$ARGUMENTS" src/`
</context>

(Note: Remove the space after the exclamation mark in actual usage) </incorporating_arguments>

<positional_arguments>

For structured input, use $1, $2, $3:

---
argument-hint: <pr-number> <priority> <assignee>
---

<objective>
Review PR #$1 with priority $2 and assign to $3.
</objective>

Usage: /review-pr 456 high alice </positional_arguments> </arguments_intelligence>

<file_structure>

Project commands: .claude/commands/

• Shared with team via version control
• Shows (project) in /help list

Personal commands: ~/.claude/commands/

• Available across all your projects
• Shows (user) in /help list

File naming: command-name.md → invoked as /command-name </file_structure>

<yaml_frontmatter>

<field name="description">
**Required** - Describes what the command does

description: Analyze this code for performance issues and suggest optimizations

Shown in the /help command list. </field>

<field name="allowed-tools">
**Optional** - Restricts which tools Claude can use

allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*)

Formats:

• Array: allowed-tools: [Read, Edit, Write]
• Single tool: allowed-tools: SequentialThinking
• Bash restrictions: allowed-tools: Bash(git add:*)

If omitted: All tools available </field> </yaml_frontmatter>

<arguments>
<all_arguments_string>

Command file: .claude/commands/fix-issue.md

---
description: Fix issue following coding standards
---

Fix issue #$ARGUMENTS following our coding standards

Usage: /fix-issue 123 high-priority

Claude receives: "Fix issue #123 high-priority following our coding standards" </all_arguments_string>

<positional_arguments_syntax>

Command file: .claude/commands/review-pr.md

---
description: Review PR with priority and assignee
---

Review PR #$1 with priority $2 and assign to $3

Usage: /review-pr 456 high alice

Claude receives: "Review PR #456 with priority high and assign to alice"

See references/arguments.md for advanced patterns. </positional_arguments_syntax> </arguments>

<dynamic_context>

Execute bash commands before the prompt using the exclamation mark prefix directly before backticks (no space between).

Note: Examples below show a space after the exclamation mark to prevent execution during skill loading. In actual slash commands, remove the space.

Example:

---
description: Create a git commit
allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*)
---

## Context

- Current git status: ! `git status`
- Current git diff: ! `git diff HEAD`
- Current branch: ! `git branch --show-current`
- Recent commits: ! `git log --oneline -10`

## Your task

Based on the above changes, create a single git commit.

The bash commands execute and their output is included in the expanded prompt. </dynamic_context>

<file_references>

Use @ prefix to reference specific files:

---
description: Review implementation
---

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

(Note: Remove the space after @ in actual usage)

Claude can access the referenced file's contents. </file_references>

<best_practices>

1. Always use XML structure

# All slash commands should have XML-structured bodies

After frontmatter, use XML tags:

• <objective> - What and why (always)
• <process> - How to do it (always)
• <success_criteria> - Definition of done (always)
• Additional tags as needed (see xml_structure section)
