# game-dev-agent

AI agent that orchestrates Unity game development tasks via CLI. Companion

agent).

## What it does

Modules (each = subagent):

- **`asset_gen`** — Generate sprites / tiles / UI icons via ComfyUI + SDXL,

auto-save to Unity Assets folder with proper import settings

- **`code_assist`** — Unity-aware C# scaffolding: MonoBehaviour / ScriptableObject /

Editor scripts. Knows Unity 2022.3 API.

- **`balance_tune`** — Read ScriptableObject configs + JSON balance files,

propose parameter tuning. Game-dev specific (beyond what general AI

code assistants do).

- **`audio_gen`** — BGM via Suno (operator-provided files), SFX via local

AudioCraft / freesound API. Auto-conform to Unity AudioClip import.

- **`runtime_director`** (in-game AI) — LLM-driven event generation for

the game itself, demonstrating dev-time + runtime AI agent patterns.

## Why this skill matters

**Career positioning**: combines deep game-dev domain (operator's

existing strength) with AI agent engineering (rare, emerging hire-niche).

Portfolio = (this agent) + (game built with it) = T-shape proof.

**Operator-specific**:

- Operator has 10+ year game dev background

- AI agent engineer roles emerging in game industry + general tech

- Game industry downturn — pure game-dev roles competitive

- AI agent angle = downturn-resilient niche

## Usage (planned, Day 1)

```bash

# Generate a sprite

python skills/game-dev-agent/scripts/agent.py gen-sprite \

"evil knight enemy, 2D pixel art, top-down view, simple silhouette" \

--output Assets/Sprites/enemy_knight.png

# Scaffold Unity MonoBehaviour script

python skills/game-dev-agent/scripts/agent.py code \

"PlayerMovement: top-down 2D, WASD input, 5 m/s speed" \

--output Assets/Scripts/PlayerMovement.cs

# Analyze + propose balance changes

python skills/game-dev-agent/scripts/agent.py balance \

--config Assets/Configs/enemies.json \

--goal "make wave 5 challenging but beatable"

# Generate BGM via Suno (operator provides Suno prompt template)

python skills/game-dev-agent/scripts/agent.py audio \

--style "lofi dungeon synth, slow, atmospheric" \

--output Assets/Audio/BGM_dungeon.mp3

```

## Development phases

Per [`docs/skill-3-design.md`](../../docs/skill-3-design.md):

- **Day 1**: agent.py orchestrator + asset_gen MVP + initial sprite

- **Day 2**: code_assist (Unity C# scaffold)

- **Day 3**: balance_tune

- **Day 4**: utility AI integration (used by game prototype)

- **Day 5**: runtime_director (AI Director — LLM events)

- **Day 6**: audio_gen + polish

- **Day 7**: portfolio docs + demo video + commit

Each end-of-day = build runnable (game prototype side).
