Skill Generator

Generate new Claude Code skills following established patterns and best practices.

Conceptual Foundation

A skill is a specialized capability that Claude can invoke to perform specific development tasks. Skills follow the context-aware pattern:

User discusses requirements → Skill invoked → References context → Generates code
                    ↑                                    ↓
            (no file paths)                    (no Q&A prompts)

Key principle: Skills reference conversation context automatically. They don't parse files or ask questions—they infer requirements from what's already been discussed.

---

The Context-Aware Pattern

Skills shifted from file-parsing/Q&A to context-awareness because:

1. Claude reads naturally - Files are read into context like any other information
2. Conversation is primary - Requirements are discussed before invocation
3. No rigid input format - No need for structured specification files
4. Specifications are documentation - Not machine-parsed inputs, but human reference

Anti-Pattern (Old Approach)

## Inputs

**Primary mode:** File path to Markdown specification
/skill-name specs/component-spec.md

**Fallback mode:** Conversational protocol (asks questions if no file provided)

Pattern (Context-Aware Approach)

## How to Use This Skill

**Invocation:**
/skill-name

**Prerequisites:**
- Requirements understood from conversation context
- (Specific prerequisites for this skill)

**Workflow integration:**
This skill is typically used after (context). The skill references
conversation context automatically—no file paths or Q&A needed.

---

Required Skill Sections

Every skill must have these sections:

1. Front Matter (YAML)

---
name: skill-name
description: One-line description. Use when (trigger conditions).
---

Description format:

• First sentence: What the skill generates
• Second sentence: When to use it (triggers)

2. Title and Introduction

# Skill Name

Brief description of what this skill generates.

## Conceptual Foundation

> For full architecture context, see [Architecture.md](../../docs/Architecture.md)

Explain the "why" before the "how":
- What problem does this solve?
- Where does this fit in the architecture?
- What are the key concepts?

Use diagrams for complex relationships:

┌─────────────┐      ┌─────────────────┐      ┌─────────────┐
│   Source    │ ───► │    Generator    │ ───► │   Output    │
│   (Input)   │      │  (This Skill)   │      │  (Artifact) │
└─────────────┘      └─────────────────┘      └─────────────┘

## How to Use This Skill

**Invocation:**
/skill-name

**Prerequisites:**
- Requirement 1 understood from conversation context
- Requirement 2 discussed or documented
- Requirement 3 identified

**Workflow integration:**
This skill is typically used (when/after what). The skill references
conversation context automatically—no file paths or Q&A needed.
Often follows (related-skill).

Key elements:

• Simple invocation (no arguments)
• Prerequisites list (what needs to be in context)
• Workflow integration (where this fits)
• Related skills mention

7. Pattern Implementation

## Pattern Implementation

This skill references conversation context to determine (what it builds):

### (Type) Detection

From conversation context, the skill identifies:
- **Key element 1** (from prior discussion or specifications read by Claude)
- **Key element 2** (from requirements already in context)
- **Key element 3** (from codebase or discussion)

### (Aspect) Analysis

From requirements already in context:
- **Design decision 1** (what guides this choice)
- **Design decision 2** (what guides this choice)

### (Output) Generation

Based on detected patterns:
1. First generated artifact
2. Second generated artifact
3. Third generated artifact

### Context Sources

Skill references information from:
- **Prior conversation**: Requirements discussed with user
- **Specification files**: If Claude has read specs/docs into context
- **Codebase analysis**: From reading existing code patterns
- **Related artifacts**: From other skills or previous generation

Structure:

• Detection sections - What the skill identifies from context
• Analysis sections - How the skill interprets requirements
• Generation section - What the skill produces
• Context Sources - Where information comes from

8. Key Patterns

## Key Patterns

### Pattern Name 1

Explain the pattern with code examples:

```swift
// Code example showing the pattern

Pattern Name 2

Another important pattern...

Show concrete examples of what the skill generates.

### 9. File Templates

```markdown
## File Templates

See [reference.md](reference.md) for complete file templates.

Reference a separate file with full templates (don't inline massive templates).

10. Naming Conventions

## Naming Conventions

| Concept | Convention | Example |
|---------|------------|---------|
| File name | `{Pattern}` | `UserViewModel.swift` |
| Test name | `{Pattern}Tests` | `UserViewModelTests.swift` |

Establish consistent naming across generated files.

Sections to NEVER Include

❌ Collaboration Protocol

## Collaboration Protocol

1. Confirm X with user
2. Ask about Y
3. Generate Z one file at a time with feedback

Why not: This implies Q&A interaction, which contradicts context-aware pattern.

❌ Generation Process with "Ask:"

## Generation Process

### Step 1: Understand Requirements

Ask:
1. **What is the name?**
2. **What fields does it have?**

Why not: Skills infer from context, they don't ask questions.

❌ File Input Documentation

## Inputs

**Primary mode:** File path to specification
/skill-name specs/spec.md

**Fallback mode:** Q&A if no file provided

Why not: Claude reads files naturally into context. No special input mode needed.

Language Patterns

✅ Use This Language

• "From conversation context, the skill identifies..."
• "Based on requirements already in context..."
• "References information from prior discussion..."
• "The skill detects..."
• "If Claude has read (files) into context..."

❌ Avoid This Language

• "Ask the user..."
• "Confirm with the user..."
• "The skill accepts file paths..."
• "Conversational fallback mode..."
• "Parse the specification file..."

Skills Don't Need Q&A Because...

1. Requirements are discussed first - Before invoking a skill, the user and Claude discuss what's needed
2. Claude reads naturally - Files are just more context, not special input
3. Context persists - Information from earlier in conversation is available
4. Skills can ask IF needed - If genuinely unclear, the skill can ask—but this should be rare

The workflow:

User: "I need a ViewModel for the dashboard"
↓
[Discussion of requirements - properties, relationships, etc.]
↓
User: "/fosmvvm-viewmodel-generator"
↓
Skill references prior discussion → Generates ViewModel

NOT:

User: "/fosmvvm-viewmodel-generator"
↓
Skill: "What properties does the ViewModel have?"
↓
User: "Title, cards, user"
↓
Skill: "What types are those?"

---

Skill Generator Workflow

When creating a new skill:

1. Understand the Domain

• What does this skill generate?
• What architecture/framework does it support?
• What are the key concepts?

2. Identify Triggers

When should this skill be invoked?

• After what discussion?
• Following which other skills?
• For what user request?

3. Map Inputs to Context

What information does the skill need?

• From prior conversation
• From files Claude has read
• From codebase analysis

4. Design Detection Logic

How does the skill identify:

• Component type/category
• Properties/fields
• Relationships
• Constraints

5. Define Generation Strategy

What files does it create?

• In what order?
• With what dependencies?
• Following what patterns?

6. Document Patterns

Show concrete examples:

• Code snippets
• File structures
• Naming conventions

7. Link Related Skills

What skills work together?

• Prerequisites (run before)
• Complements (run after)
• Alternatives (run instead)

---

Testing Your Skill

After creating a skill, verify:

1. Invocation is simple - Just /skill-name, no arguments
2. Prerequisites are clear - What must be in context?
3. Detection is documented - How does it identify types/patterns?
4. Generation is concrete - Real code examples, not abstract descriptions
5. Context sources are listed - Where does information come from?
6. No Q&A language - No "Ask:", "Confirm:", "The user provides:"
7. Version history started - v1.0 with today's date

Common Pitfalls

1. Over-Specifying Input Format

❌ Bad:

The skill accepts JSON in this format:
{
  "name": "ComponentName",
  "fields": [...]
}

✅ Good:

From conversation context, the skill identifies:
- Component name (from prior discussion)
- Fields (from requirements already in context)

2. Building File Parsers

❌ Bad:

The skill parses the specification file to extract field definitions.

✅ Good:

If Claude has read specification files into context, the skill
references that information.

3. Q&A Protocols

❌ Bad:

Step 1: Ask what type of component
Step 2: Ask what properties it has

✅ Good:

From conversation context, the skill identifies:
- Component type
- Properties

4. Assuming Skill Runs Blind

❌ Bad:

The skill cannot proceed without a specification file.

✅ Good:

Prerequisites:
- Requirements understood from conversation context

5. Generic "Handle All Cases"

❌ Bad:

This skill generates any type of component based on user input.

✅ Good:

This skill generates ViewModels for MVVM architecture.
(Specific purpose, specific output)
