Game Build Executor

What it does

• Splits building into whitebox (probe the riskiest design question) and production (implement the approved design) stages, declaring buildStage and buildPath up front.
• Reads GAME_DESIGN.md (plus ART_DIRECTION.md for production) and compresses only product boundaries, must-preserve experience facts, run instructions and completion evidence into build/BUILD_BRIEF.md.
• Forces a minimal-but-complete core loop first: boot → real input → state change → outcome → restart, before any presentation layer.
• Puts all state commits behind a deterministic rules arbiter; the model may parse free input and narrate, but cannot mutate resources, position, knowledge or win/loss directly.
• Pins content/rules/save versions, initial state, seed and input sequences, and logs events so failing paths can be replayed without re-calling online models.
• Never silently swaps to a web build when the target toolchain is missing; records targetRuntime, testedRuntime and uncovered items separately, with NOT_AVAILABLE: reason for unknowns.
• Hands final QA verdicts to the game-qa skill instead of writing them itself.

Who it's for

• Teams running a multi-stage novel/script-to-game pipeline
• Developers of text or simulation games where an LLM narrates but rules must stay deterministic
• Anyone who wants prototypes backed by reproducible evidence rather than demos that merely look playable

Examples

1. "Prototype only the riskiest question — the real-time control feel" → narrowest playable whitebox plus structured observations returned to the design owner.
2. "Implement the approved design" → BUILD_BRIEF, a runnable candidate, and one authoritative verification command for game-qa.
3. "Fix what playtesters found" → localize the failure to a node, patch it, then replay the failing path and neighbouring counter-examples.
