gamedev-shipping

gamedev-shipping is a skill for Claude Code, Codex from ericrisco/rsc-harness. It costs 99 tokens per session (3,639 once invoked), scanned A, original, MIT.

A guide to exporting, packaging, signing, and publishing games made with Godot, Unity, or Unreal. It covers turning a project into a build for desktop, web, mobile, or stores such as Steam and the App Store.

In plain words
What is it for?
Use it to configure engine exports, create platform builds, sign Android and iOS packages, prepare web builds, and submit games to stores.
Why use it?
It helps avoid platform-specific build failures and missing signing or store requirements. It also distinguishes the shipped game package from the gameplay code inside it.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

gamedev-shipping 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 7d 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.

Ship the game — export, build & release (per engine · per platform)

Take a finished project from editor → signed, correctly-configured artifact → live on the right target (desktop / web / mobile / store), with the platform gotchas that silently break a build handled up front. This skill owns the packaging and release boundary; the engine skills own the code that runs inside the artifact.

Version anchors (what "current" means here — July 2026)

Tool Target Ship note
Godot 4.5 stable (4.6 dev) Export templates must match the editor build exactly (4.5.1 editor ⇒ 4.5.1 templates). C#/.NET edition has NO web export — GDScript/standard only.
Unity Unity 6 (6000.x) "Build Settings" is now Build Profiles. IL2CPP backend for iOS/Android/WebGL.
Unreal 5.6 Ship in the Shipping config; test packaged builds in Development.
Android JDK 17, target a recent API level AAB required for Google Play (new apps + updates). APK only for sideload/itch/direct.
iOS/macOS Xcode 16+, notarytool altool notarization is dead — use xcrun notarytool.

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.
