Agent Skill
Steam Publish skill
steam-publishgamedev-skills/awesome-gamedev-agent-skillsskills/workflows/steam-publish/SKILL.md
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.

Install the Steam Publish skill
Skills CLI (Claude Code, Codex, Cursor and others)
npx skills add https://github.com/gamedev-skills/awesome-gamedev-agent-skills --skill steam-publish
Claude Code, by hand (all projects)
git clone --depth 1 https://github.com/gamedev-skills/awesome-gamedev-agent-skills.git /tmp/awesome-gamedev-agent-skills mkdir -p ~/.claude/skills cp -R /tmp/awesome-gamedev-agent-skills/skills/workflows/steam-publish ~/.claude/skills/steam-publish
For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.
What it costs your context
Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.
| When | What loads | Cost |
|---|---|---|
| Every session | Name and description | 71 tok |
| When the agent uses it | The SKILL.md instructions | 2,678 tok |
| Only if opened | 2 bundled files (52 KB) | varies |
Until it is used, steam-publish costs about 19× less than the median MCP server we measured (1,363 tokens on every turn). Installing all 75 skills from gamedev-skills/awesome-gamedev-agent-skills would load 6,712 tokens of descriptions. Skills vs MCP study

The headings of its SKILL.md. Read the full file on GitHub.
- Steam Publish (Steamworks + SteamPipe)
- When to use
- Prerequisites (do these once, in order)
- Core workflow
- Patterns
- 1. SteamPipe ContentBuilder layout (Steamworks SDK)
- 2. Minimal app build script — appbuild1000.vdf
- 3. Check the build scripts before uploading (read-only, no login)
- 4. Upload the build (Windows; substitute the platform builder elsewhere)
- 5. Iterate safely with a preview build (uploads nothing)

- ai-behavior-trees-utility-aigamedev-skills/awesome-gamedev-agent-skills
Build a production behavior-tree runtime (Blackboard, action/condition leaves, sequence/selector/parallel composites, decorators) and a Utility AI system (response curves — linear, exponential, sigmoid, quadratic — considerations, and action evaluators), plus hybrid BT-drives-Utility agents. Use when implementing a reusable behavior-tree or utility-based decision system, or tuning enemy/NPC decisions beyond a simple FSM, or when the user mentions behavior tree, blackboard, decorator, selector, sequence, tick status, utility AI, response/scoring curve, or consideration. For choosing between FSM/BT/steering or for pathfinding, use game-ai; for Unreal's BehaviorTree/Blackboard assets, use unreal-behavior-trees.
