# using-isometric-skills

A meta-skill that picks the right specialized skill for an isometric game task and sets the order to run them, before any code or art gets written.

## What it does

Isometric projects go wrong when you dive into a renderer or a sprite sheet with no workflow behind it. This skill takes the incoming request, sorts it into one phase — Art Foundations, Asset Generation, Asset Processing, Engine & Rendering, Gameplay or Polish — and opens the matching skill from its routing table. Improvising is off the table; you follow the skill it points to.

The table covers a lot of ground: ground tiles, props, buildings, 8-direction characters, animated water and fire, background removal, atlas packing, autotiling, grid math, canvas rendering, depth sorting, map format, pathfinding, camera controls, tile picking, performance, pipeline automation. When a task crosses phases, the router lays them out as a pipeline: art, assets, processing, engine, gameplay, polish.

One rule sits above the rest: lock art direction first. Every asset skill leans on a single agreed style sheet, so generating sprites before that sheet exists means doing them twice. Come back to the router whenever the user changes scope.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add 0xheycat/isometric-game-skills --skill using-isometric-skills -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/using-isometric-skills/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/using-isometric-skills/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add 0xheycat/isometric-game-skills --skill using-isometric-skills -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/using-isometric-skills/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add 0xheycat/isometric-game-skills --skill using-isometric-skills -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/using-isometric-skills/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install 0xheycat/isometric-game-skills using-isometric-skills
```

2. **Manually: put the files in place**
- File: `.github/skills/using-isometric-skills/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add 0xheycat/isometric-game-skills --skill using-isometric-skills -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/0xheycat/isometric-game-skills --path skills/using-isometric-skills
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/using-isometric-skills/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add 0xheycat/isometric-game-skills --skill using-isometric-skills -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/0xheycat/isometric-game-skills/tree/HEAD/skills/using-isometric-skills/SKILL.md

## When to use it
- figure out which skill to start an isometric task with
- sequence the phases when art and engine work overlap
- hold off asset generation until the style is locked
- match a task description to the right skill in the set
- re-route after the user changes scope

## Example prompts
- I want to build an isometric game — which skill do I start with?
- Make grass tiles and houses in one consistent style, and lay out the skill order
- My 8-direction characters lag on canvas: which skills run, and in what order?

# Using Isometric Skills (Router)

## Overview

This is the meta-skill. Isometric games fail when you jump straight into code or art without picking the right workflow. This skill maps an incoming request to the exact specialized skill that should handle it, in the correct order: art direction -> asset generation -> asset processing -> engine -> gameplay -> polish.

## When to Use

- The user asks for anything isometric and you are not sure which skill applies.
- You are tempted to free-style a renderer, tile, or sprite without a workflow.
- A task spans multiple stages (art + engine) and needs sequencing.

## Process

1. Classify the request into one phase: Art Foundations, Asset Generation, Asset Processing, Engine & Rendering, Gameplay, or Polish.
2. Open the matching skill from the table below and follow it exactly. Do not improvise.
3. If the task spans phases, run skills in pipeline order (art -> assets -> processing -> engine -> gameplay -> polish).
4. Lock art direction FIRST. Every asset skill depends on a single agreed style sheet.
5. Return to this router whenever the user changes scope.

### Routing table

| If the task is about... | Use skill |
|---|---|
| Low-VRAM ComfyUI / model setup | `comfyui-lowvram-setup` |
| Choosing a consistent art style | `isometric-art-direction` |

| Trees, rocks, props | `isometric-object-sprites` |
| Houses, barns, shops | `isometric-building-sprites` |
| Characters, 8-direction | `isometric-character-sprites` |
| Animated water, fire, windmills | `animated-sprite-generation` |
| Removing backgrounds / edges | `transparent-cutout-cleanup` |
| Packing sprites into an atlas | `spritesheet-atlas-packing` |
| Auto edge transitions | `autotiling-transitions` |
| Grid <-> screen math | `isometric-grid-math` |
| Drawing the world on canvas | `canvas2d-isometric-renderer` |
| Things drawn in wrong order | `depth-sorting-occlusion` |
| Map file format | `tilemap-data-format` |
| Moving units around obstacles | `isometric-pathfinding` |
| Pan / zoom camera | `camera-pan-zoom-controls` |
| Click-to-select a tile | `tile-picking-interaction` |
