ase-deliver: Instructions file for Codex

AGENTS.md

ase-deliver AGENTS.md is an instructions file for Codex, OpenCode from ylty1516/ase-deliver. It costs 980 tokens per session, scanned A, original, MIT.

Repository instructions for ase-deliver, a tool that packages game artwork into Aseprite files, sprite sheets, GIF previews, and engine metadata. Aseprite is a pixel-art editor, and the instructions require the editable .aseprite file as the source deliverable.

In plain words
What is it for?
Following the artwork workflow: initialize a project, prepare source images, build the deliverables, validate them, and optionally open them in Aseprite.
Why use it?
They prevent an agent from treating a standalone image as finished when the project requires layered, animated, and validated game-art files.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is ylty1516/ase-deliver's own configuration. It tells Codex and OpenCode how to work on ase-deliver itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ase-deliver configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ase-deliver AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AseDeliver — contract for any AI

You are producing shippable Aseprite game art, not a pretty PNG.

Source of truth is always out/<name>.aseprite. A PNG/GIF without that file is not done.

What this tool is

ase-deliver turns a JSON spec + frame images (or ASCII pixels) into:

  • .aseprite with layers, frames, tags, palette, pivot/slices
  • sprite sheet PNG
  • GIF preview
  • engine JSON (frames + meta.frameTags)

It does not replace your image model. You generate pixels however you can. This compiler makes them deliverable in Aseprite.

Do this, in order

  1. doctor — confirm Pillow; Aseprite is optional for compile, required to open the file.
  2. init a project from a template. Fill description with the subject.
  3. brief — follow the returned prompt and exact filenames.
  4. Put one image per required name in raw/. Magenta #FF00FF background. Isolated subject. Integer scale of the canvas is OK.
  5. build (ingest + compile + export + validate).
  6. Only report done if validate.deliverable is true.
  7. open in Aseprite if the user wants to see it.

CLI (Windows):

C:\Users\yyx\ase-deliver\ase-deliver.bat doctor
C:\Users\yyx\ase-deliver\ase-deliver.bat templates
C:\Users\yyx\ase-deliver\ase-deliver.bat init hero --template character-platformer --out D:\game\art\hero --desc "orange fox knight, facing right"
C:\Users\yyx\ase-deliver\ase-deliver.bat brief D:\game\art\hero
C:\Users\yyx\ase-deliver\ase-deliver.bat build D:\game\art\hero
C:\Users\yyx\ase-deliver\ase-deliver.bat open D:\game\art\hero

Python module:

python -m ase_deliver <command>

Set PYTHONPATH=C:\Users\yyx\ase-deliver if you are not cwd'd there.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
