Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
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 →
- high Privilege Escalation · line 111 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.
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 | $0.00099 | $0.03639 |
| Opus 5 | $0.00049 | $0.01819 |
| Sonnet 5 | $0.00020 | $0.00728 |
| Haiku 4.5 | $0.00010 | $0.00364 |
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.
How it starts
The opening of the file, as written. The whole thing — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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. |
When NOT to use — and who owns it instead
| Ask | Owner | Why the line is there |
|---|---|---|
| Gameplay, shaders, netcode, physics — any runtime logic | ../godot/SKILL.md, ../unity/SKILL.md, ../unreal/SKILL.md, ../gamedev-shaders/SKILL.md, ../gamedev-multiplayer/SKILL.md, ../gamedev-physics/SKILL.md |
This skill packages code, it does not write it. The boundary is the export button. |
| Hosting a normal web app, API or container (Dockerfile, Coolify, Vercel, VPS) | ../deployment/SKILL.md |
A WebAssembly game is static files; only its headers are special (below). Borrow its Actions + header-setting patterns. |
| Game feel, economy, narrative | ../game-design/SKILL.md, ../game-storytelling/SKILL.md |
Design intent, not packaging. |
| Signing-key and CI secret handling in general | ../secure-coding/SKILL.md |
The practice this skill assumes for keystores/certs. |
What ships with it
5 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.
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.

gamedev-shipping is a skill published in the GitHub repository ericrisco/rsc-harness (78 stars, last pushed today), licensed MIT. It adds 99 tokens to every session and 3,639 once invoked, about $0.0005 per session on Opus 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 2026-09-03.
