# steam-publish

A skill that walks a finished build through Steam: depots and packages, steamcmd uploads, beta branches, review checklists. Useful when the game is ready but the store page isn't.

## What it does

The skill splits a Steam release into two tracks that run at once: the store page and the build. It keeps the order straight, from launch options and depots in App Admin through a `steamcmd` upload and a build set live on a branch, then the Game Build checklist and store review. Before uploading it runs `python scripts/check_steam_build.py <app_build.vdf>` and works through every error, since unpublished app config is the usual reason uploads fail.

Setup takes planning. You need a partner account with the Steam Direct fee paid ($100 per app, and Valve holds first titles for 21 days between payment and release), a separate build account limited to Edit App Metadata and Publish App Changes To Steam, and the Steamworks SDK under `tools/ContentBuilder/` on the uploading machine. A Steam Mobile Authenticator or SMS is needed as well, otherwise the account cannot set a build live on `default` once the game has shipped.

A reference file, `references/steampipe-build-scripts.md`, covers depot scripts, CI/CD and troubleshooting. The skill stays out of the in-game Steamworks API, so achievements, cloud saves and the overlay belong to the engine integration. Each review takes roughly 3-5 business days, and an approved title does not release itself — someone clicks Release App. Worth knowing before you pin a launch date: the page has to sit in Coming Soon for at least 2 weeks.

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/gamedev-skills/awesome-gamedev-agent-skills/tree/HEAD/skills/workflows/steam-publish/SKILL.md

## When to use it
- wire up depots and packages for a new app
- upload a build with steamcmd and get a BuildID
- push a build to a beta branch before launch
- run the store page and build review checklists
- ship an update to a game that is already live

## Example prompts
- Check `app_build_1000.vdf` with `python scripts/check_steam_build.py` and upload the build with steamcmd
- Set the latest build live on the beta branch and tell me what's left before review
- Run the Game Build checklist before we mark it ready for review

  Publish or update a game on Steam with Steamworks and SteamPipe: configure depots and
  packages, upload builds with steamcmd, set a build live on a branch, and run the release
  checklists. Use for Steam publishing, app_build.vdf/steamcmd uploads, depots, beta branches,
  or a store page release.

# Steam Publish (Steamworks + SteamPipe)

Take a finished build to a live Steam store page. Two tracks run in parallel and both must be
approved before release: the **store page** (presence) and the **build** (SteamPipe upload +
the release checklists). This skill is the operational checklist; deep build-script,
CI/CD, and troubleshooting detail lives in `references/steampipe-build-scripts.md`.

## When to use

- Use when setting up a Steam app, building/editing the store page, configuring depots and
  packages, uploading a build via SteamPipe/steamcmd, managing beta branches, or releasing
  and updating a Steam title.
- Triggers: `steam_appid.txt`, the Steamworks SDK `tools/ContentBuilder`, `app_build_*.vdf`,
  `steamcmd`, "publish on Steam", "depot", "set build live".

**When *not* to use:** publishing on itch.io (use `itch-publish`); writing the
Steamworks **API** in-game (achievements/cloud/overlay live in engine SDK integrations, not
here); store/financial *advice* (pricing strategy, tax) — direct the user to Steamworks docs
and their own counsel.

## Prerequisites (do these once, in order)

1. **Partner account + Steam Direct fee.** Onboarding asks for legal identity, bank and tax
   details (tax verification can take up to 30 days). Each new app needs the Steam Direct fee
   (USD $100 or equivalent per app at time of writing): not refundable, recouped once the
   product reaches $1,000 Adjusted Gross Revenue, and not payable with Steam Wallet funds.
   You receive an **App ID** — find it on your Steamworks homepage. Treat the App ID as the
   key to everything below. For your first few titles, Valve also enforces a **21-day wait**
```
