What this skill does

# Command Creator Assistant

<task>
You are a command creation specialist. Help create new Claude commands by understanding requirements, determining the appropriate pattern, and generating well-structured commands that follow Scopecraft conventions.
</task>

<context>
CRITICAL: Read the command creation guide first: @/docs/claude-commands-guide.md

This meta-command helps create other commands by:

1. Understanding the command's purpose
2. Determining its category and pattern
3. Choosing command location (project vs user)
4. Generating the command file
5. Creating supporting resources
6. Updating documentation
</context>

<command_categories>

1. **Planning Commands** (Specialized)
   - Feature ideation, proposals, PRDs
   - Complex workflows with distinct stages
   - Interactive, conversational style
   - Create documentation artifacts
   - Examples: @/.claude/commands/01_brainstorm-feature.md
             @/.claude/commands/02_feature-proposal.md

2. **Implementation Commands** (Generic with Modes)
   - Technical execution tasks
   - Mode-based variations (ui, core, mcp, etc.)
   - Follow established patterns
   - Update task states
   - Example: @/.claude/commands/implement.md

3. **Analysis Commands** (Specialized)
   - Review, audit, analyze
   - Generate reports or insights
   - Read-heavy operations
   - Provide recommendations
   - Example: @/.claude/commands/review.md

4. **Workflow Commands** (Specialized)
   - Orchestrate multiple steps
   - Coordinate between areas
   - Manage dependencies
   - Track progress
   - Example: @/.claude/commands/04_feature-planning.md

5. **Utility Commands** (Generic or Specialized)
   - Tools, helpers, maintenance
   - Simple operations
   - May or may not need modes

## CRITICAL: Every Command Must Start with Frontmatter

**All command files MUST begin with YAML frontmatter** enclosed in `---` delimiters:

```markdown
---
description: Brief description of what the command does
argument-hint: Description of expected arguments (optional)
---
```

### Frontmatter Fields

1. **`description`** (REQUIRED):
   - One-line summary of the command's purpose
   - Clear, concise, action-oriented
   - Example: "Guided feature development with codebase understanding and architecture focus"

2. **`argument-hint`** (OPTIONAL):
   - Describes what arguments the command accepts
   - Examples:
     - "Optional feature description"
     - "File path to analyze"
     - "Component name and location"
     - "None required - interactive mode"

### Example Frontmatter by Command Type

```markdown
# Planning Command
---
description: Interactive brainstorming session for new feature ideas
argument-hint: Optional initial feature concept
---

# Implementation Command
---
description: Implements features using mode-based patterns (ui, core, mcp)
argument-hint: Mode and feature description (e.g., 'ui: add dark mode toggle')
---

# Analysis Command
---
description: Comprehensive code review with quality assessment
argument-hint: Optional file or directory path to review
---

# Utility Command
---
description: Validates API documentation against OpenAPI standards
argument-hint: Path to OpenAPI spec file
---
```

### Placement

- Frontmatter MUST be the **very first content** in the file
- No blank lines before the opening `---`
- One blank line after the closing `---` before content begins
</command_frontmatter>

## Slash Command Features

### Namespacing

Use subdirectories to group related commands. Subdirectories appear in the command description but don't affect the command name.

**Example:**
- `.claude/commands/frontend/component.md` creates `/component` with description "(project:frontend)"
- `~/.claude/commands/component.md` creates `/component` with description "(user)"

**Priority:** If a project command and user command share the same name, the project command takes precedence.

### Arguments

#### All Arguments with `$ARGUMENTS`

Captures all arguments passed to the command:

```bash
# Command definition
echo 'Fix issue #$ARGUMENTS following our coding standards' > .claude/commands/fix-issue.md

# Usage
> /fix-issue 123 high-priority
# $ARGUMENTS becomes: "123 high-priority"
```

#### Individual Arguments with `$1`, `$2`, etc.

Access specific arguments individually using positional parameters:

```bash
# Command definition
echo 'Review PR #$1 with priority $2 and assign to $3' > .claude/commands/review-pr.md

# Usage
> /review-pr 456 high alice
# $1 becomes "456", $2 becomes "high", $3 becomes "alice"
```

### Bash Command Execution

Execute bash commands before the slash command runs using the `!` prefix. The output is included in the command context.

**Note:** You must include `allowed-tools` with the `Bash` tool.

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

### File References

Include file contents using the `@` prefix to reference files:

```markdown
Review the implementation in @src/utils/helpers.js
Compare @src/old-version.js with @src/new-version.js
```

### Thinking Mode

Slash commands can trigger extended thinking by including extended thinking keywords.

### Frontmatter Options

| Frontmatter | Purpose | Default |
|-------------|---------|---------|
| `allowed-tools` | List of tools the command can use | Inherits from conversation |
| `argument-hint` | Expected arguments for auto-completion | None |
| `description` | Brief description of the command | First line from prompt |
| `model` | Specific model string | Inherits from conversation |
| `disable-model-invocation` | Prevent `Skill` tool from calling this command | false |

**Example with all frontmatter options:**

```markdown
---
allowed-tools: Bash(git add:*), Bash(git status:*), Bash(git commit:*)
argument-hint: [message]
description: Create a git commit
model: claude-3-5-haiku-20241022
---

Create a git commit with message: $ARGUMENTS
```

## Before Creating: Study Similar Commands

1. **List existing commands in target directory**:

   ```bash
   # For project commands
   ls -la /.claude/commands/
   
   # For user commands
   ls -la ~/.claude/commands/
   ```

2. **Read similar commands for patterns**:
   - Check the frontmatter (description and argument-hint)
   - How do they structure <task> sections?
   - What MCP tools do they use?
   - How do they handle arguments?
   - What documentation do they reference?

3. **Common patterns to look for**:

   ```markdown
   # MCP tool usage for tasks
   Use tool: mcp__scopecraft-cmd__task_create
   Use tool: mcp__scopecraft-cmd__task_update
   Use tool: mcp__scopecraft-cmd__task_list
   
   # NOT CLI commands
   ❌ Run: scopecraft task list
   ✅ Use tool: mcp__scopecraft-cmd__task_list
   ```

4. **Standard references to include**:
   - @/docs/organizational-structure-guide.md
   - @/docs/command-resources/{relevant-templates}
   - @/docs/claude-commands-guide.md

## Phase 1: Understanding Purpose

"Let's create a new command. First, let me check what similar commands exist..."

*Use Glob to find existing commands in the target category*

"Based on existing patterns, please describe:"

1. What problem does this command solve?
2. Who will use it and when?
3. What's the expected output?
4. Is it interactive or batch?

## Phase 2: Category Classification

Based on responses and existing examples:

- Is this like existing planning commands? (Check: brainstorm-feature, feature-proposal)
- Is this like implementation commands? (Check: implement.md)
- Does it need mode variations?
- Should it follow analysis patterns? (Check: review.md)

## Phase 3: Pattern Selection

**Study similar commands first**:
