dsh-cli-anything-aseprite

Aseprite pixel-art studio for DeepSeek Harness (DSH).

An agent-usable CLI harness for the Aseprite pixel-art editor, built with the CLI-Anything methodology, plus a DSH plugin that turns it into 18 model tools. The AI draws pixel art like a human — one deliberate stroke at a time — and every stroke is rendered live as an ANSI terminal frame, so humans can watch the AI work in real time.

DSH 像素画工作室：AI 像人类一样分步绘制像素画（打形→底色→阴影→高光），
每一步操作实时渲染到终端，人类全程可见。

✨ Features

• Human drawing vocabulary: pixel / line (Bresenham) / rect / ellipse /

flood fill / eraser — plus symmetry (h/v/both), tiled mode (seamless textures), gradient (rgb16 interpolation).

• Selection (Aseprite semantics): fill / stroke / clear / copy (persistent

clipboard) / paste / move / get.

• Layers: add / remove / duplicate / merge / opacity / visibility /

reference layers (rotoscoping, excluded from render).

• Animation: frames, durations, frame tags, onion-skin ghost

rendering in the terminal.

• Canvas: free size 1..1024², presets (icon…max), **resize with 9-grid

anchor, nearest-neighbor rescale**.

• Colors: classic palettes (pico8/db16/sweetie16/na16) + **rgb16:r,g,b

4096-color mode** (16×16×16 indexed RGB).

• Export: PNG (nearest upscale) / animated GIF / sprite sheet PNG+JSON /

PNG sequence / native .aseprite binary (hand-written ASE writer, opens in the real Aseprite).

• Undo/redo across CLI processes (sidecar persistence), crash-safe

concurrent saves.

• 73/73 tests (unit + E2E, including byte-level .aseprite format checks).
• Optional live monitor UI (draggable overlay: ANSI canvas, preview zoom,

layers with opacity sliders, export buttons, project switcher, workdir picker) — loaded as a DSH dynamic plugin, see monitor/.

📦 Install

1. Install the Python harness

pip install -e ./python        # provides the `cli-anything-aseprite` CLI

Requires Python ≥ 3.10, click, Pillow. No Aseprite binary needed — the harness implements the document model, drawing primitives, and the native .aseprite file format itself. If a real aseprite binary exists, set ASEPRITE_BIN to enable advanced batch conversion.

2. Install the DSH plugin

From a checkout:

dsh plugin add ./dsh-cli-anything-aseprite

From npm (once published):

dsh plugin add dsh-cli-anything-aseprite

From GitHub:

dsh plugin add github:YOUR_USER/dsh-cli-anything-aseprite

Then verify the layer applied:

dsh --dump-config | grep cli-anything-aseprite

The plugin registers 18 pixelart_* tools in every session of that profile. Workdir defaults to ~/.dsh/aseprite-work (override with the plugin config: workdir: row or ASEPRITE_WORKDIR env).

🚀 Quick start (AI draws a sprite)

1. Open a DSH session (profile with this bundle installed).
2. Ask: *"画一个 32×32 的像素勇者，pico8 调色板"* — or drive the tools manually:

   pixelart_new {name: "hero", preset: "sprite", palette: "pico8"}
   pixelart_draw {op: "line", x: 9, y: 7, x1: 9, y1: 13, color: "#1d2b53"}
   pixelart_draw {op: "rect", x: 10, y: 7, w: 12, h: 7, color: "#1d2b53"}
   pixelart_draw {op: "rect", x: 10, y: 7, w: 12, h: 4, color: "#ff004d", fill: true}
   pixelart_terminal {}     # → live ANSI frame (human-watchable)
   pixelart_export {format: "png", scale: 8}
   pixelart_export {format: "aseprite"}   # → hero.aseprite, opens in Aseprite

1. Watch the terminal frame after every stroke — the AI's canvas is always

visible.

🏗️ How it works (architecture)

model tools (pixelart_*)                 DSH Host plugin (src/index.js)
      │  JSON args
      ▼
cli-anything-aseprite --file X.pxa --json <cmd>     Python harness (python/)
      │
      ├── core/canvas.py   drawing primitives → sparse cel model
      ├── core/export.py   PNG/GIF/sheet/PNG-seq + .aseprite binary writer
      └── utils/terminal.py ANSI truecolor half-block frames (human view)

State persists per project as <name>.pxa (JSON document) + sidecars (.history.json undo stack, .clipboard.json selection clipboard, .modes.json symmetry/tiled) — so undo, clipboard and modes survive separate CLI processes, exactly like a real editor session.

Every mutating tool refreshes the in-memory state and returns version, which drives the live monitor UI (polling pix-state).
