AntiPattern

Engine API Drift Traps

unity-pattern-porting-mismatch

Engine-specific APIs fail silently or with compile-time errors when Unity patterns are reused in s&box—async tasks outlive destroyed components, transforms use obsolete properties, and raycasts use the wrong tracing entry points.

MATCHESSolution

Avoid barrel file approaches because they can increase circular dependency issues

MATCHESSolution

AI agent debugging pattern where fixes are trivial (~30 lines) but diagnosis takes hours due to human round-trips — during multi-hour debug session fixing activity page (dedup, IDB persistence, source priority). Tension: Each round costs minutes of wall-clock time. Outcome: Eliminates ping-pong entirely when self-test infra is in place.

MATCHESSolution

Upgrade Angular to a version where the CommonEngine bug is fixed, and switch SSR rendering to use AngularNodeAppEngine with server-side routing enabled (instead of CommonEngine). Configure the server routing/app engine accordingly so parameterized routes resolve on direct requests.

MATCHESSolution

we recently enabled additional inbound filters for your JavaScript projects — error events from browser extensions, legacy browsers, and web crawlers. Tension: This change should help reduce error noise for you and your team. Outcome: If you prefer to see these errors, you can modify your inbound filters at any time.

MATCHESSolution

Change the engine async fixture from session scope to function scope (remove scope="session") so all async fixtures/tests run on the same event loop, preventing the cross-loop Future/Task error.

MATCHESSolution

fail-LOUD when the local model can't load — the local model can't load. Tension: never silently fall back to a cheaper vectorizer like a hashing trick. Outcome: that swaps the geometry under the index.

MATCHESSolution

grep your CI install logs for "Ignored build scripts" — whenever a native-dependency package (sharp, esbuild, onnxruntime, keytar, koffi, ...) misbehaves only in CI. Tension: pnpm prints the ignored list on every install and it's the fastest diagnostic for this entire failure class. Outcome: the fastest diagnostic for this entire failure class.

MATCHESSolution

Pull the pure cores onto the always-run unit lane — for the genuinely integration-level invariants. Tension: a skipped test is not a passing test.

MATCHESSolution

bound it with a "progress ceiling" — a process emitting bytes but making NO semantic progress. Tension: a process emitting bytes but making NO semantic progress (livelock) would be shielded forever. Outcome: re-arms recovery after a long no-progress window even while bytes flow.

MATCHESSolution

The trivial solution is to build a backend — What are my options? Tension: I don't want to start implementing all the original API methods. Outcome: I just prefer to use it directly from the client.

MATCHESSolution

display error messages from API responses (both nested and non-nested). Tension: The alert system should be available globally across all components. Outcome: Alerts should be dynamically triggered based on different responses (error, success, etc.).

MATCHESSolution

Use NavMeshAgent component for AI pathfinding — In s&box, AI navigation uses NavMeshAgent component. Outcome: Let agent update position automatically.

MATCHESSolution

Use Component.Task (TaskSource) for all async work inside components — inside components. Tension: it auto-cancels when the component is destroyed.

MATCHESSolution

BLOCKED → USE INSTEAD — s&box enforces an API whitelist. Tension: many standard .NET types and namespaces are blocked for security. Outcome: use the s&box equivalents instead of blocked .NET APIs.

MATCHESSolution

Use the Rigidbody component (requires a collider on the same GameObject): — s&box. Outcome: physics won't simulate.

MATCHESSolution

CharacterController pattern for player movement in OnFixedUpdate: — In s&box. Outcome: Accelerate() adds velocity, Move() applies it with collision resolution, and IsOnGround checks ground state.

MATCHESSolution

DebugOverlay (available on any Component or GameObject) for debug visualization. Tension: Unity's Debug.DrawLine/DrawRay don't exist. Outcome: Draw a sphere at a world position for 0.1 seconds.

MATCHESSolution

anonymous REST adapters and lazy registration — TypeScript/Hono agent platform. Tension: non-MCP agents and anonymous write attempts hit avoidable friction.

MATCHESSolution

Use ClutterComponent for GPU-instanced environmental detail scattering: — From code — invalidate tiles when terrain changes:. Outcome: Regenerate all clutter.

MATCHESSolution

Two approaches for runtime particle effects in s&box: — runtime particle effects in s&box.

MATCHESSolution

Track objects in `OnPostSpawn` and `OnPostToolAction` events. Outcome: Count by iterating only the player's list, pruning destroyed objects lazily during the count.

MATCHESSolution

Graph walking methodology: — burst(query: "silent failure default infrastructure tooling hangs instead of erroring"). Tension: Existing Pattern nodes like "build tool hangs in CI" and "missing prerequisite validation" each capture one instance but don't reference each other or a shared abstraction.

MATCHESSolution

Don't build per-client adapters. — client capabilities change with updates. Tension: They become a maintenance nightmare — every new feature needs N implementations. Outcome: one delivery function that degrades.

MATCHESSolution

Game developers prefer C++ for engines and performance-sensitive subsystems — for engines and performance-sensitive subsystems. Tension: maximal control over performance, memory layout, and platform integration while keeping runtime overhead minimal.

MATCHESSolution

Cache in OnAwake — Key s&box performance patterns from the optimizer skill:. Tension: GetComponent every frame. Outcome: Physics work in OnFixedUpdate.

MATCHESSolution

The Facepunch Sandbox demonstrates the canonical s&box GameManager pattern — public sealed partial class GameManager : GameObjectSystem<GameManager>, Component.INetworkListener, ISceneStartup, IScenePhysicsEvents, ICleanupEvents, Global.ISaveEvents. Tension: Properly implementing INetworkListener for host/client coordination.

MATCHESSolution

Rebuilt App.tsx as the OracleController beat machine. Outcome: running the authored cascade arrest→anchor→recognition→locked on setTimeout timers.

MATCHESSolution

Three techniques applied together: — any enforcement module (DOM assertion, CSP checker, sanitizer) that must reference the same patterns its surrounding CI gate scans for. Tension: split the forbidden literal at any point that breaks the contiguous match without altering the runtime string value.

MATCHESSolution

tsx blocks auto http/undici instrumentation — tsx runtime. Tension: auto-instrumentation won't fill the gap.

MATCHESSolution

top-level apps/api. Outcome: needs its own instrumentation.ts + inbound extraction of the signed-header-adjacent trace context.
