/aseprite:studio Take any Aseprite request end to end
The front door for any Aseprite or pixel-art request. Works out what the user actually wants, picks which workflows to run and in what order — and whether to work in the user's open Aseprite window or a headless batch Aseprite (--headless / --live force it) — hands parts to the specialist agents where the harness has them, and does not stop until the result has been looked at and reviewed. Use when a request spans several steps ("make me an animated knight for Godot") or when you are unsure which workflow applies.

The other workflows each do one thing well. This one decides which of them the request needs, runs them in the order that keeps mistakes cheap, and owns the result until it is finished. It does not replace them: at every step, read the workflow it names and follow that — do not do the step from memory.
Procedure
#Pick the Aseprite, then
preflight. Two places the work can happen: live, the user's open window, which they watch and can undo; or headless, a batch Aseprite this server runs with no window, where the only results are yourlookpreviews and the files you save. Decide before the first call, from the request — see Live or headless below — and pass it:preflight mode="headless"orpreflight mode="live". When the request says nothing either way, callpreflightwithoutmodeand keep the mode the server started in.If not ready, stop and tell the user what to fix. Nothing below works without Aseprite, and editing files on disk instead is never an acceptable recovery. In headless there is no window: show previews as you go and save (
sprite_manageopsave_as) before reporting.Read the room.
sprite_infoon whatever is open. An open sprite changes the plan: "make it bigger" means a sprite that exists, and its canvas and palette answer questions you would otherwise have to ask.Classify the request against the table below. Most requests are one row; a big one ("animated knight, export for Godot") chains several. Write the chain down before starting — it is the plan you report progress against.
Decide once whether to ask. Open-ended requests start with
aseprite:brief, which puts every decision to the user in one message. Specific requests ("add a 1px outline", "export this as a GIF") do not — just do them. Never ask more than once per stage: a user who asked for a whole animation does not want to approve every frame.Design before drawing. Anything new — a character, a prop, a scene, an animation — goes through
aseprite:conceptbefore a pixel is placed: it writes the art spec (scenario, palette, poses), turns it into a prompt for an image model, and offers the user two ways on: generate a concept sheet or storyboard with that prompt and send it back, or continue without one. That offer rides in the brief's message when there is a brief, so the user still answers once. If they will send references, stop and wait; when the images arrive,aseprite:conceptreads them into a PixelSpec and imports them. If the user already supplied reference art, skip the prompt and go straight to reading it.Run the chain. For each stage, read its skill (
skill://<name>) and follow it. Hand a stage to a specialist agent when your harness has one (see below) — the agent reads the same rules, so the result is the same whether it runs or you do.Look after every stage that changed pixels.
lookoppreviewfor the read, opasciiwhen position matters, opcomparewhen there is a reference. A stage is done when you have seen its result, not when its tool reported success.Get judged by someone who did not draw it. For anything you drew or changed, hand the result to the
pixel-criticagent where the harness has one — never grade your own work in place of it; you know what you meant, so you see it. Give it the document name and the brief, nothing about how it was made. Elsewhere, runaseprite:reviewand do its cold read first.The critique decides whether you iterate at all. A draft ships as it is when its critique has no BLOCKING finding and scores 7/10 or more — note its other findings in your report and stop. Below that, or while any BLOCKING finding remains, fix it — at most three fix rounds. Stopping a weak draft only because nothing was marked BLOCKING leaves it weak.
Each round fixes the BLOCKING findings, or when there are none the one change the critic names as its first fix — never a general polish. A fresh critic always finds something, and each finds something different; polishing on that alone rebuilds parts that already worked. The guards below are what keep a round from doing that:
- Snapshot before you touch it.
export op="png"the current frame (orop="gif"for an animation) to a scratch path, and keep an exact copy of every layer you will change —export op="aseprite"to a scratch path, or the layer's rows fromlook op="ascii". Restoring means writing those rows back as agridat the same x/y, or opening the copy andlayer op="duplicate" toSprite=<document>. - Fix, don't redraw. A fix changes the pixels the finding points at —
read that region with
look op="ascii", change those rows, write them back as agrid— or recolours a mass that is too dark (recolor). If the round changed more than about a quarter of a layer's opaque pixels, it was a redraw: restore the snapshot and make the smaller fix. Never touch pixels the brief says must stay as they are. - Decide by comparison, not by score. Scores from separate critic calls
are not on one scale — the same tree drew 5/10 from one critic and 4/10
from the next. After the fix, export the new version next to the
snapshot, and give one critic call both images, in an order it cannot
read anything into (
a.png,b.png, coin-flipped), asking which is the better sprite for the brief and whether the BLOCKING finding is gone. Keep the fix only if it picks the new one; otherwise restore. Two rounds in a row that the comparison rejects end the loop.
Do not change pixels after the last critique; anything you edit afterwards goes back to the critic. A critique whose cold read did not name your subject is the most important finding you will get: the picture does not say what you think it says. Report each round: the BLOCKING finding, what you changed, and which version the comparison chose.
- Snapshot before you touch it.
Report in a few lines: what exists now (document, layers, tags, files written), what you decided on the user's behalf, what you compromised on and why — including where the sprite departs from the reference on purpose. Show it — a
lookpreview or the exported file's path, not an adjective.
Live or headless
#Read the flags first, then the request. The first row that matches decides.
| The request | Mode |
|---|---|
contains --headless (or says "headless", "без окна", "in the background", "don't open Aseprite") |
headless, forced — do not second-guess it |
contains --live (or "in my Aseprite", "in the window", "so I can watch") |
live, forced |
| edits something open in the user's window — "this sprite", "the selected layer", "fix my knight" | live — the art is there, not on disk |
produces files and nothing else: a batch of assets, sprites generated into a folder, a CI or build step, a spritesheet from .aseprite files on disk, a run on a machine with no display |
headless |
| anything else — draw me a knight, animate this, a palette | no mode: keep what the server started in (live, unless the operator ran it with --headless) |
Strip the flag from the request before reading the rest of it: --headless a knight is a request for a knight.
Then the one rule that matters: the mode is chosen from the request, never
from a failure. If live preflight says Aseprite is not attached, do not
switch to headless to get the work done anyway — tell the user, and if the
work would suit headless, offer it as one question ("Aseprite isn't open —
open it, or should I work headless and save the files to …?"). Switch only on
their answer. A user who wanted to watch in their window and got files
instead has been ignored, and the .aseprite they had open is a file you were
never meant to write.
Switching mid-task is allowed when the user asks for it; each side keeps its
own documents. Headless refuses to open or save a file the user's window has
open (file_open_in_editor) — that refusal is the answer, not an obstacle to
route around. Say which mode you used in the report.
Routing
#| The user wants | Chain |
|---|---|
| Something new, loosely described ("a knight") | aseprite:brief + aseprite:concept (one message) → aseprite:new → aseprite:palette if the palette is not settled → aseprite:draw → aseprite:shade → aseprite:review |
| Something new, fully specified | aseprite:concept → aseprite:new → aseprite:draw → aseprite:shade → aseprite:review |
| Pixel art of a picture the user supplied ("make this character a sprite") | aseprite:brief if size or palette is open → aseprite:concept from its reference step → aseprite:new → aseprite:draw → aseprite:review |
| An animation of a character | the drawing chain above if nothing exists yet, with a storyboard in the concept prompt → aseprite:rig → aseprite:animate → aseprite:review |
| An animation of a sprite that is already rigged | aseprite:concept for the storyboard (offer) → aseprite:animate → aseprite:review |
| Tiles, terrain, level art | aseprite:brief if open-ended → aseprite:concept (an environment sheet) → aseprite:tileset → aseprite:review |
| Colours changed, a retro look, a cleanup | aseprite:palette → aseprite:review |
| Volume, light, "it looks flat" | aseprite:shade → aseprite:review |
| A change to existing art ("make it more menacing", "fix the hands") | aseprite:fix → aseprite:review |
| An opinion ("is this good?", "why does it look off?") | aseprite:review only — report, do not edit unless asked |
| Files for an engine or for sharing | aseprite:review if not already done → aseprite:export |
| Words on the art — a label, score, title card | aseprite:draw (its Text section) → aseprite:review |
| Nine-slice UI panels, pivots or hotspots for an engine | aseprite:export (slices) |
| Share the finished work in the community gallery | aseprite:review if not already done → aseprite:submit |
If a request fits no row, it is usually a direct tool call ("rename the layer",
"add a frame"): make it, look if pixels changed, and say what you did.
Subject rules
#Before a stage draws or animates something, read the rule files for its
subject — every stage, and every agent you hand a stage to. Two or three files
is normal; reading all of them is not. Each one has size budgets, mistakes, a
review list and ```grid templates to transcribe with draw op grid.
Specialists
#Claude Code and omp ship four agents. Use them when the harness offers them; elsewhere, run the matching skill yourself.
| Agent | Takes over | Instead of |
|---|---|---|
palette-smith |
proposing and justifying a palette | aseprite:palette |
rig-builder |
planning and building the layer rig | aseprite:rig |
animation-director |
key poses, timing and tags before frames are drawn — and the storyboard panels for the concept prompt | the planning half of aseprite:animate |
pixel-critic |
a scored, located critique; read-only | aseprite:review |
Give an agent the brief, the PixelSpec if there is one, the document name and the stage it owns — it starts with no memory of this conversation. Run agents one at a time: they all edit the same open document, and two at once will fight over the active layer and frame.
What this workflow must not do
#- Skip the brief on an open-ended request to seem fast. Guessed size and palette cost a full redraw when they are wrong.
- Skip the concept offer on something new because drawing straight away looks faster. The user decides whether to generate references; you decide only how to phrase the prompt.
- Pixelize a reference — downscale it onto the canvas and call it art. It is a guide for shapes and poses; the pixels are still drawn.
- Ask about things a default covers. Light from the upper-left is not worth a round trip.
- Declare done without
lookand a review. A tool result saying pixels changed is not evidence the sprite is right. - Leave the user's document in a state they did not ask for — stray scratch layers, a changed active frame, colours added to the palette without saying so.
