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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00089 | $0.01285 |
| Opus 5 | $0.00044 | $0.00642 |
| Sonnet 5 | $0.00018 | $0.00257 |
| Haiku 4.5 | $0.00009 | $0.00128 |
Grade A, and why
unreal-packaging 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 9d 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.
This is a copy
88% identical to unreal-packaging — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Unreal Packaging & Cooking
Turn a UE5 project into a runnable, distributable build: choose the right build configuration, cook content, set the launch map, and package — from the editor or the command line. Targets UE 5.4+.
When to use
- Use when producing a build (test or release), choosing Development vs Shipping, cooking
content, configuring Packaging / Maps & Modes settings, or automating builds with
RunUAT BuildCookRunfor CI. - Use when the project has a
*.uprojectandConfig/Default*.ini, and the goal is a packaged player rather than running in-editor.
When not to use: storefront submission/release process → steam-publish / itch-publish.
Editor-time gameplay/iteration is not packaging.
Core workflow
- Set the launch map. Project Settings → Maps & Modes → Game Default Map is what a packaged build loads first. Wrong/empty here is the most common "packaged game is black" cause.
- Pick the build configuration: Development (default; optimized but keeps logging/
stats/console for testing) vs Shipping (all optimizations, debugging tools stripped — for
release).
DebugGame/Debugare for debugging engine/game code and aren't for distribution;DebugGameisn't available for Blueprint-only projects. - Understand cook vs package. Cooking converts assets to the target platform's format
and packs them into
.pakfiles. Packaging bundles the compiled executable + cooked content into a standalone, distributable set of files. Packaging runs a cook as part of it. - Package from the editor: the Platforms menu → choose the platform (e.g. Windows) → set the Binary Configuration → Package Project → pick an output folder.
- Or build from the command line with the Unreal Automation Tool (
RunUAT BuildCookRun) for repeatable/CI builds. - Tune Packaging settings (Project Settings → Packaging): which maps/directories to cook, full-rebuild, compression, and whether to build all maps.
- Verify by running the packaged build, not just by a successful cook — launch the executable and confirm it loads the right map and runs.
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.

unreal-packaging is a skill published in the GitHub repository ukanwat/aaabench (382 stars, last pushed 25d ago), licensed MIT. It adds 89 tokens to every session and 1,285 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to unreal-packaging, differing in 8 lines, and is treated as a copy.
