Summary

• add reducer context examples for deterministic random values across TypeScript, C#, Rust, and C++
• clarify the context-provided random API usage that the agent skills already reference
• correct the C++ example to match the SDK's inclusive gen_range(min, max) behavior

Validation

• pnpm --dir docs build passed.
  • Docusaurus emitted the existing llms-txt warning for /docs/ask-ai/ask-ai, then completed successfully.
• TypeScript snippet calls typechecked with tsc against sdks/typescript/src/server/rng.ts and sdks/typescript/src/server/sys.d.ts:
  • ctx.random()
  • ctx.random.integerInRange(1, 6)
  • ctx.random.fill(new Uint8Array(16))
• Rust RNG context examples passed existing doctests:
  • cargo test -p spacetimedb --doc rng --features rand
• C++ snippet syntax checked against the SDK headers:
  • clang++ -std=c++20 -Icrates/bindings-cpp/include -x c++ -fsyntax-only -
  • The compile emitted existing warning noise for WASM import/export attributes, but exited successfully.
• C# was not compiled locally because dotnet is not installed on this host. The documented ctx.Rng.NextDouble() and ctx.Rng.Next(1, 7) calls were checked against the generated/runtime context source where ReducerContext.Rng is a System.Random.

Notes

• A package-wide TypeScript declarations build was not used as validation here because this checkout currently fails before the snippet on missing optional Solid typings (solid-js / solid-js/store).
