Unreal Packaging skill
unreal-packaginggamedev-skills/awesome-gamedev-agent-skillsskills/unreal/unreal-packaging/SKILL.md
Package and ship an Unreal Engine 5 project: the Platforms menu Package Project flow, build configurations (Development vs Shipping), cooking content, packaging settings and the Game Default Map, and command-line builds with RunUAT BuildCookRun. Use when packaging a build, making a shipping build, cooking content, configuring packaging settings, or when the user mentions package Unreal, cook content, shipping build, or BuildCookRun.

Install the Unreal Packaging skill
Skills CLI (Claude Code, Codex, Cursor and others)
npx skills add https://github.com/gamedev-skills/awesome-gamedev-agent-skills --skill unreal-packaging
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/unreal/unreal-packaging ~/.claude/skills/unreal-packaging
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 | 89 tok |
| When the agent uses it | The SKILL.md instructions | 1,194 tok |
| Only if opened | No bundled files | — |
Until it is used, unreal-packaging costs about 15× 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

- Core workflow
- Patterns
- 1. Editor packaging (the menu path)
- 2. Command-line build with UAT (CI-friendly)
- 3. Cook only (no packaging), e.g. to refresh content

- 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.
