Game Build Execution (game-build)

Compresses an approved game design and art direction into a minimal BUILD_BRIEF, then drives implementation of a genuinely playable build with evidence-based iteration.

Dev & CodingAdvanced★ 668⑂ 100AI score 7/10Last updated: Aug 17, 2026

What it does

  • Reads GAME_DESIGN.md and ART_DIRECTION.md and writes build/BUILD_BRIEF.md containing only product boundaries, must-preserve experience facts, run instructions and completion evidence.
  • Hands implementation to the current coding agent or a stronger model without re-litigating concept, level or art decisions.
  • Forces a minimal-but-complete core loop first: launch → real input → state change → outcome → restart.
  • Records the actual toolchain plus install/build/start commands and versions; unknowns must be written as NOT_AVAILABLE: reason instead of guessed.
  • Keeps targetRuntime and testedRuntime separate, logs uncovered platform/input/perf items as limitations, and leaves the final QA verdict to the game-qa skill.

Who it's for

  • Teams using the novel-to-game pipeline to turn narrative source material into playable prototypes.
  • Anyone who wants to stop agents from claiming "done" on builds that never actually run.
  • Producers who want platform, engine and scope decisions frozen in docs before implementation.

Example uses

  • "Implement the approved game design as a running prototype" → BUILD_BRIEF first, then the core loop.
  • "The target engine toolchain isn't installed" → no silent switch to a web build; NOT_AVAILABLE and limitations are recorded instead.
  • "Get this ready for QA" → produces one authoritative verification command and minimal observable state so game-qa can run clean start → core action → outcome → restart in a single pass.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/game-build folder from the GitHub repo worldwonderer/novel-to-game into my ~/.claude/skills/game-build/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/worldwonderer/novel-to-game.git && mkdir -p ~/.claude/skills && cp -r novel-to-game/skills/* ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repository: git clone https://github.com/worldwonderer/novel-to-game.git
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy the skills: cp -r novel-to-game/skills/* ~/.claude/skills/ (copy all of them, since game-build depends on sibling skills such as game-qa).
  5. Verify the contract docs exist under ~/.claude/skills/game-build/references/.
  6. Restart Claude Code and confirm the skill is recognized.
  7. Prepare PRODUCT_BRIEF.md, GAME_DESIGN.md and ART_DIRECTION.md in your project, then ask Claude to "build the game from the approved design".
