What is godot-build-optimization?

A tool for examining a Godot game project and preparing smaller engine export builds. Godot is a game engine; the tool creates version-aware build settings and a report about the resulting artifact size.

Use it to inspect a Godot project, generate SCons and build-profile files, and report which build choices affect package size.

It helps remove unused engine modules and avoid guesswork when reducing the size of exported games. It keeps the scan and generated files separate from the project and engine source.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00056	$0.00708
Opus 5.5	$0.00022	$0.00283
Sonnet 5.5	$0.00011	$0.00142
Haiku 4.5	$0.00006	$0.00071

Security

Grade A, and why

godot-build-optimization 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/optimize_build.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Godot Build Optimization

Use the bundled scripts/optimize_build.py helper from the repository or installed package. It performs a bounded static scan and writes only to the explicit output directory; it does not edit project.godot, export presets, or engine source.

Inspect the project and target first. Run plan and review the detected renderer, text scripts, 2D/3D, navigation, XR, archive, and asset evidence:
```
python scripts/optimize_build.py plan --project <project> --target windows
```
Generate files only after the plan is appropriate for the target. Pass the exact Godot source version when it is known and keep output in a dedicated staging directory:
```
python scripts/optimize_build.py generate \
  --project <project> --target windows --godot-version 4.5 \
  --output <staging>/godot-build-size
```
This creates custom.py, build_config.gdbuild, and optimization-report.json. Compile matching export templates with the generated files, for example:
```
scons platform=windows profile=<staging>/godot-build-size/custom.py \
  build_profile=<staging>/godot-build-size/build_config.gdbuild
```
Use --minimal-modules only when the project has runtime smoke coverage. It sets modules_enabled_by_default=no and enables only modules visible in the scan. Add --force <feature> when a feature is loaded dynamically or otherwise cannot be found statically. Treat every generated disable as a hypothesis until the release artifact launches cleanly.
Export to a clean directory with the matching custom template, then launch that artifact without the editor. Check the first scene, localized text, input, saves, native extensions, and startup logs. Measure the result and preserve the report and digest:
```
python scripts/optimize_build.py measure --artifact <exported-file> \
  --output <staging>/artifact-size.json
```

Read Size optimization guidance before choosing fallback text, module allowlisting, UPX, Wasm-opt, or Brotli. These choices can remove runtime features or change memory, antivirus, and hosting behavior.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

godot-build-optimization is a skill published in the GitHub repository dcc-mcp/dcc-mcp-godot (3 stars, last pushed yesterday), licensed MIT. It adds 56 tokens to every session and 708 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
