Phase 1: Command Requirements

Step 1.1: Gather Information

If not provided, ask:

Essential:

• Command name? (use dash-case: create-feature, run-tests)
• What does this command do? (one-sentence purpose)
• What arguments does it accept?

Optional:

• Should this command be constrained to specific tools? (e.g., only git commands)
• Does this command need inline context? (e.g., !git status output)
• Is this command part of a larger workflow?

Step 1.2: Analyze Similar Commands

Search for similar commands to learn patterns. Consider:

Workflow Commands (multi-phase processes):

• feature-dev - 7-phase feature development
• create-component - Component scaffolding
• Pattern: Discovery ->†-> Planning ->†-> Approval ->†-> Implementation ->†-> Documentation

Git Commands (version control):

• commit - Create commits with smart messages
• commit-push-pr - Full workflow from commit to PR
• clean_gone - Clean up deleted branches
• Pattern: Git operations with strict tool constraints

Interactive Commands (user guidance):

• new-sdk-app - Interactive app creation wizard
• Pattern: Ask questions ->†-> Validate ->†-> Execute

Analysis Commands (code review):

• Component verification, pattern checking
• Pattern: Analyze -> Report findings -> Optional fixes

Describe 1-2 relevant examples.

---

Phase 2: Command Design

Step 2.1: Choose Command Pattern

Based on requirements, select a pattern:

Pattern A: Simple Command

• Single-phase execution
• Minimal user interaction
• Example: Clean up branches, format code

Pattern B: Workflow Command

• Multiple phases (Discovery -> Planning -> Execution)
• User approval gates
• Todo list tracking
• Example: Feature development, component creation

Pattern C: Interactive Command

• Ask clarifying questions
• Validate inputs
• Execute with confirmation
• Example: Scaffolding, configuration

Pattern D: Analysis Command

• Gather context
• Analyze code
• Generate report
• Optional remediation
• Example: Code review, pattern verification

Step 2.2: Design Command Structure

Present the command structure:

## Command Design: /[command-name]

**Pattern:** [A/B/C/D]
**Purpose:** [one-sentence description]
**Arguments:** [description of expected arguments]

### Tool Constraints (if any)

[List allowed tools or "No constraints"]

### Phases

1. **[Phase 1]** - [what it does]
2. **[Phase 2]** - [what it does]
   ...

### Workflow

[Brief description of the flow]

### Example Usage

\`\`\`
/command-name [example arguments]
\`\`\`

Approve? (yes/no)

Wait for approval.

Phase 3: Implementation

Step 3.1: Create Frontmatter

Generate YAML frontmatter based on requirements:

Basic Frontmatter:

---
description: Brief description of what this command does
argument-hint: Description of expected arguments
---

With Tool Constraints:

---
description: Brief description of what this command does
argument-hint: Description of expected arguments
allowed-tools: Bash(git add:*), Bash(git commit:*), Bash(git push:*)
---

Tool Constraint Examples:

• Bash(git:*) - Only git commands
• Bash(npm:*), Bash(yarn:*) - Only package managers
• Read, Grep, Glob - Only read operations
• Edit, Write - Only file modifications
• TodoWrite - Only todo list updates

Step 3.2: Create Command Header

# [Command Name]

You are [role description]. [Core responsibility and expertise].

User request: $ARGUMENTS

---

Role Examples:

• "You are a senior React engineer specializing in component architecture."
• "You are a git workflow expert who creates clean, semantic commits."
• "You are a code reviewer focused on security and best practices."

## Key Principles

1. **Principle 1** - [Explanation]
2. **Principle 2** - [Explanation]

1. [Question 1]
2. [Question 2]
3. [Question 3]

Wait for answers.

---

## Phase 2: Validation

### Step 2.1: Confirm Understanding

Present:

```markdown
## Configuration Summary

- [Setting 1]: [value]
- [Setting 2]: [value]

Proceed? (yes/no)
```

Wait for confirmation.

Phase 3: Execution

[Implementation steps]

---

Phase 4: Completion

[Summary and next steps]

#### For Analysis Commands (Pattern D):

```markdown
## Phase 1: Context Gathering

### Step 1.1: Identify Files
[Instructions for finding relevant files]

### Step 1.2: Load Context
[Instructions for reading and understanding code]

---

## Phase 2: Analysis

### Step 2.1: [Analysis Type]
[What to look for]

### Step 2.2: Score Findings
[If using confidence scoring]

Only report issues with e80% confidence.

---

## Phase 3: Report

### Step 3.1: Generate Report

Format:
```markdown
## Analysis Results

### Issues Found ([count])

#### [Issue Category]
**Confidence: [percentage]**
**Location:** [file:line]
**Description:** [what's wrong]
**Recommendation:** [how to fix]

Step 3.2: Optional Remediation

Ask user: "Would you like me to fix these issues?"

---

Key Principles

1. Be thorough - Analyze all relevant code
2. Be confident - Only report high-confidence findings
3. Be actionable - Provide clear recommendations

### Step 3.4: Add Inline Context (if needed)

Commands can use inline bash commands for context:

```markdown
## Phase 1: Gather Context

Examine the current state:
- !git status - See file changes
- !git diff --staged - See staged changes
- !git log -5 --oneline - See recent commits

Based on this context, [do something]...

Common Inline Commands:

• !git status - Current git state
• !git diff - Changes in working directory
• !git log - Commit history
• !ls -la - File listing
• !npm list - Installed packages

Step 3.5: Add Examples and Commentary (optional but helpful)

## Examples

<example>
Context: User wants to create a login component
User: /create-component LoginForm
Assistant: I'll create a LoginForm component. Let me start by...
<commentary>
The command uses the create-component pattern to scaffold
a new component with all necessary files and patterns.
</commentary>
</example>

<example>
Context: User wants to commit changes
User: /commit
Assistant: Let me review the changes first...
<runs git status and git diff>
Assistant: I'll create a commit for these changes:
<creates commit with semantic message>
<commentary>
The commit command analyzes changes to create appropriate
commit messages following the repository's conventions.
</commentary>
</example>

Step 3.6: Complete Command File

Combine all sections:

---
description: [description]
argument-hint: [hint]
allowed-tools: [constraints if needed]
---

# [Command Name]

You are [role]. [responsibility].

User request: $ARGUMENTS

## Tool Constraint Patterns

### Git Operations Only
```yaml
allowed-tools: Bash(git:*)

Read-Only Analysis

allowed-tools: Read, Grep, Glob

File Modification Only

allowed-tools: Edit, Write

Specific Git Commands

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

Package Management

allowed-tools: Bash(npm:*), Bash(yarn:*), Bash(pnpm:*)

No Constraints

# Omit allowed-tools field entirely

---

Key Principles

1. Clear Purpose - One command, one responsibility
2. Constrain Appropriately - Use tool restrictions to prevent scope creep
3. Guide the User - Explicit phases and approval gates
4. Use Context - Inline commands provide relevant information
5. Error Handling - Account for edge cases and failures
6. Document Thoroughly - Examples and principles clarify intent
7. Test Extensively - Verify with real scenarios
8. Iterate - Refine based on actual usage

---

Common Mistakes to Avoid

1. Vague Descriptions - Be specific about what the command does
2. Missing Constraints - Commands without constraints can do anything
3. No Approval Gates - Workflow commands need user confirmation
4. Poor Argument Handling - Validate and explain expected arguments
5. Missing Examples - Complex commands need usage examples
6. No Success Criteria - Include verification checklists
7. Inconsistent Numbering - Use consistent phase/step numbering
8. Assuming Context - Gather necessary context explicitly
