# Skill & Agent Integration Proposal

## Spyke Games - Claude Code Enhanced Development Workflow

> **Prepared for:** CTO Review
> **Date:** 2026-01-06
> **Status:** Proposal

---

## Executive Summary

This proposal outlines an AI-augmented development workflow using **Claude Code** with custom **Skills** and **Agents** to:

1. **Codify institutional knowledge** into reusable AI skills
2. **Automate quality gates** via specialized agents
3. **Enable pair programming** where Claude implements while developers observe and validate
4. **Ensure consistency** - any developer produces senior-quality code

**Expected Outcome:** New team members can produce production-ready code that follows all architectural patterns, passes review automatically, and matches team standards from day one.

---

## Current Workflow Challenges

| Challenge | Impact | Current Mitigation |
|-----------|--------|-------------------|
| MVC violations (UnityEngine in Controller) | Breaks testability, requires refactoring | Manual code review |
| Async safety issues (stale refs, missing CancellationToken) | Race conditions, hard-to-debug bugs | Senior developer knowledge |
| Missing PrepareForReuse/Dispose | Memory leaks, level replay bugs | PR checklist (manual) |
| Inconsistent patterns across developers | Technical debt accumulation | Documentation (not always read) |
| Onboarding time for new developers | 2-3 months to full productivity | Mentorship, pair programming |

---

## Proposed Solution: Skills + Agents

### What Are Skills?

Skills are **structured knowledge packages** that give Claude Code deep understanding of:
- Our codebase architecture (MVCN, Zenject, UniTask)
- Our coding patterns and conventions
- Our common pitfalls and how to avoid them
- Reference implementations to follow

**When loaded, Claude Code "knows" our codebase like a senior developer.**

### What Are Agents?

Agents are **automated specialists** that perform specific tasks:
- Analyze feature requirements against our architecture
- Generate code following our patterns
- Review PRs for violations before human review
- Scaffold new features with correct boilerplate

**Agents enforce consistency automatically.**

## Agent Specifications

### 1. Analysis Agent

**Purpose:** Analyze feature requirements and map to architecture

**Triggers:**
- "Analyze feature {name}"
- "What base class should I use for {description}"
- Starting any new feature

**Skills Loaded:**
- `yarn-flow-analysis`
- `yarn-flow-blockers`
- `yarn-flow-boosters`

**Input:** Feature name and description/ruleset

**Output:**
```markdown
## Feature Analysis: {Name}

### Classification
- Type: Grid Blocker
- Base Class: GridBlockerBaseModel
- Interface: IGridBlocker

### System Interactions
| System | Interaction | Details |
|--------|-------------|---------|
| Unstitch | Blocks covered cells | Exclude from TryGetUnstitchTarget() |
| Belt | No direct interaction | - |
| Play-On | Counter restoration | Save/restore checkpoint |

### Identified Edge Cases
1. Level ends during destruction animation
2. Multiple instances triggered simultaneously
3. Counter exceeds remaining (clamp to 0)
...

### Similar Implementations
- ThreadBox (multi-cell, direction-based entry)
- KnitCover (single-cell cover)

### Complexity Assessment: Medium
- Requires existing GridBlockerBaseModel patterns
- Direction-based entry adaptation needed

### Next Steps
1. Create DESIGN.md with full specifications
2. Get stakeholder approval on edge case behaviors
3. Proceed to implementation
```

---

### 2. Scaffold Agent

**Purpose:** Generate complete file structure following all patterns

**Triggers:**
- "Implement {type} {name}"
- "Create scaffold for {feature}"
- After design approval

**Skills Loaded:**
- `yarn-flow-blockers` or `yarn-flow-boosters` (based on type)
- `yarn-flow-di`
- `yarn-flow-pooling`
- `yarn-flow-events`

**Input:** Feature type, name, and approved DESIGN.md

**Output Files Generated:**

```
Assets/KnitGame/Scripts/
├── Model/Blockers/
│   └── {Feature}Model.cs
├── Controller/Blockers/{Feature}/
│   ├── {Feature}Controller.cs
│   └── I{Feature}Controller.cs
├── Controller/Generators/
│   └── {Feature}ModelGenerator.cs
├── View/Blockers/{Feature}/
│   ├── {Feature}View.cs
│   └── {Feature}ViewGroup.cs (if multi-cell)
└── Tests/
    ├── {Feature}ModelTests.cs
    └── {Feature}ControllerTests.cs

+ DI bindings added to KnitGameInstaller.cs
```

**Code Quality Guarantees:**
- Models extend correct base class
- Controllers implement IInitializable, IDisposable
- PrepareForReuse implemented with all state reset
- ObjectPool used in generators
- Event subscriptions balanced (subscribe in Initialize, unsubscribe in Dispose)
- No UnityEngine imports in Model/Controller
- Test files with reflection DI helper

---

### 3. PR Review Agent

**Purpose:** Automated code review before human review

**Triggers:**
- PR created
- "Review my PR"
- "Check this code"
- Pre-commit hook (optional)

**Skills Loaded:**
- `yarn-flow-pr-review`
- `yarn-flow-mvc`
- `yarn-flow-async`
- `yarn-flow-pooling`

**Checks Performed:**

| Category | Check | Severity |
|----------|-------|----------|
| **MVC** | UnityEngine import in Controller | FAIL |
| **MVC** | UnityEngine import in Model | FAIL |
| **MVC** | Direct GameObject/Transform in Controller | FAIL |
| **Lifecycle** | IInitializable without IDisposable | WARN |
| **Lifecycle** | Event subscribe without unsubscribe | FAIL |
| **Lifecycle** | Missing PrepareForReuse | WARN |
| **Async** | Async method without CancellationToken | WARN |
| **Async** | State modification after await without check | FAIL |
| **Async** | Animation ID without try-finally | FAIL |
| **Async** | Missing `_gameModel.IsLevelEnded` check | WARN |
| **Pooling** | PoolObjectBase without OnDespawn override | WARN |
| **Pooling** | OnDespawn doesn't reset all fields | WARN |
| **Style** | Debug.Log instead of SpykeLogger | WARN |
| **Style** | Magic numbers without constants | INFO |
| **Testing** | Public method without test coverage | INFO |

**Output Format:**
```markdown
## PR Review: #{PR_NUMBER}

### Summary
- 2 FAIL (must fix)
- 3 WARN (should fix)
- 1 INFO (consider)

### Issues Found

#### FAIL: UnityEngine in Controller
`ThreadCutterController.cs:15`
```csharp
using UnityEngine;  // VIOLATION: Controllers must be pure C#
```
**Fix:** Remove UnityEngine dependency, use interface for view interaction

#### FAIL: Missing CancellationToken Check
`ThreadCutterController.cs:89`
```csharp
await PlayAnimation();
UpdateState();  // UNSAFE: State may have changed during await
```
**Fix:** Add cancellation check before state modification:
```csharp
await PlayAnimation();
if (_levelCts.Token.IsCancellationRequested) return;
UpdateState();
```

#### WARN: Event Subscribe Without Unsubscribe
`ThreadCutterController.cs:45`
```csharp
_gridController.OnCellChanged += HandleCellChanged;
```
**Fix:** Add unsubscribe in Dispose():
```csharp
public void Dispose()
{
    _gridController.OnCellChanged -= HandleCellChanged;
}
```

### Recommendations
1. Fix both FAIL issues before merge
2. Address WARN issues to prevent technical debt
3. Consider INFO items for code quality improvement
```

## Developer Role Transformation

### Before: Developer as Implementer

```
Developer receives task
    → Reads docs (maybe)
    → Writes code (varies by experience)
    → Makes mistakes (caught in review)
    → Refactors (wastes time)
    → Eventually passes review

Time: 3-5 days for feature
Quality: Depends on developer experience
```

### After: Developer as Validator

```
Developer receives task
    → Analysis Agent analyzes requirements
    → Claude Code creates design docs
    → Developer validates design
    → Scaffold Agent creates structure
    → Claude Code implements logic
    → Developer observes & validates
    → PR Review Agent checks automatically
    → Developer confirms & merges

Time: 1-2 days for feature
Quality: Consistent senior-level regardless of developer experience
```

## Appendix B: Agent Prompt Templates

### PR Review Agent System Prompt

```
You are a code review agent for the Yarn Flow Unity game project.

Your job is to review code changes and identify violations of project standards.

LOADED SKILLS:
- yarn-flow-pr-review: PR checklist and common pitfalls
- yarn-flow-mvc: MVC layer rules
- yarn-flow-async: Async safety patterns

REVIEW CHECKLIST:
1. MVC Violations
   - Controllers/Models must NOT import UnityEngine
   - Views implement interfaces defined by controllers

2. Lifecycle Issues
   - IInitializable requires IDisposable
   - Events subscribed must be unsubscribed
   - PrepareForReuse must reset ALL state

3. Async Safety
   - CancellationToken must be passed and checked
   - State must be revalidated after await
   - Animation IDs must use try-finally

For each issue found, report:
- File and line number
- Severity (FAIL/WARN/INFO)
- Code snippet showing the problem
- Fix recommendation with corrected code
```

## Appendix C: Example Agent Output

### Analysis Agent Output Example

```markdown
## Feature Analysis: ThreadCutter

### Classification
| Property | Value |
|----------|-------|
| Type | Grid Blocker |
| Base Class | `GridBlockerBaseModel` |
| Interface | `IGridBlocker` |
| Shape | Single-cell |
| Collection | Direction-based (cuts thread when unstitch passes through) |

### System Interactions

| System | Interacts | Details |
|--------|-----------|---------|
| Unstitch | YES | Cuts thread, decreases remaining count |
| Belt/Tray | NO | No direct interaction |
| Grid | YES | Registered in GridModel |
| Play-On | YES | Counter restoration needed |
| Level Goals | YES | Required goal type |
| ThreadBox | YES | Can coexist on same row |

### Edge Cases Identified

1. **Timing**
   - Level ends during cut animation
   - Multiple cuts triggered same frame

2. **Spatial**
   - ThreadCutter at grid edge
   - Adjacent to another ThreadCutter

3. **State**
   - Counter reaches 0 during animation
   - Play-on during cut animation

### Complexity: Low-Medium
- Follows existing single-cell blocker patterns
- Direction-based collection similar to existing blockers

### Reference Implementations
- `KnitCover` - Single-cell grid blocker
- `ThreadBox` - Direction-based entry
```

## Conclusion

This proposal outlines a comprehensive system for AI-augmented game development that:

1. **Captures institutional knowledge** in reusable skills
2. **Automates quality enforcement** via specialized agents
3. **Enables pair programming** with Claude Code as implementer
4. **Ensures consistency** across all developers regardless of experience

The expected outcome is faster development, higher code quality, and dramatically reduced onboarding time for new team members.
