Stake Game Developer

Use this skill to design, validate, and ship Stake games with deterministic event playback and compliance gates.

Workflow

1. Define or review the game brief, modes, and constraints. Load references/workflow.md.
2. Validate book/index integrity before UI assumptions. Run scripts/validate-books-index.mjs.
3. Validate event stream contract and sequencing. Run scripts/validate-rgs-events.mjs.
4. Validate frontend integration expectations. Load references/frontend-integration.md and references/rgs-event-contract.md.20→ 5. Run compliance gate checks before release review. 21→ Run scripts/audit-checklist.mjs using references/compliance-rules.json and references/compliance-checklist.md. 22→ 23→ 6. Final Approval Check. 24→ Validate full game against references/game-approval-checklist.md (PreChecks, Math, Frontend, Jurisdiction). 25→ 26→ ## Commands“`bash node scripts/validate-books-index.mjs –index <path/to/index.json> –format text node scripts/validate-rgs-events.mjs –input <path/to/events.jsonl> –format text node scripts/audit-checklist.mjs –rules references/compliance-rules.json –target –social true –format text

Treat non-zero exits as hard blockers for release readiness.

- **Strict Currency/Math Scaling:**
  - **API (Wallet/RGS):** Use `1,000,000` scale. `display = api / 1e6`, `api = display * 1e6`.
  - **Books (Math/Events):** Use `100` scale. `multiplier = bookVal / 100`, `win = bet * (bookVal / 100)`.
  - *Never* mix these scales. See `references/currency-rules.md`.
- Keep frontend stateless: never re-calculate payouts if events already provide them.
- Validate data contracts before tuning UX or animation details.
- Enforce compliance checks by default (`--social true`) unless user explicitly says otherwise.
- When reporting findings, include file path and line when available.
