This skill covers testing ZX games for determinism and correctness. Use when the user asks about "sync testing", "replay testing", "determinism", "desync", "checksums", "test my game", or "verify determinism". **Load references when:** - Determinism patterns → `references/determinism-rules.md`
/plugin marketplace add nethercore-systems/nethercore-ai-plugins/plugin install zx-test@nethercore-ai-pluginsThis skill inherits all available tools. When active, it can use any tool Claude has access to.
references/determinism-rules.mdRuns two identical instances, compares checksums each frame.
nether run --sync-test
nether run --sync-test --frames 3000 # Specific duration
Pass criteria: Identical checksums for 1000+ frames.
Record and replay for regression testing:
nether run --record replay.bin # Record
nether run --replay replay.bin # Playback
Workflow:
| Do | Don't |
|---|---|
zx::random() | rand::thread_rng() |
BTreeMap, BTreeSet | HashMap, HashSet |
| Frame counter | Instant::now() |
| Fixed-point math | Floating-point accumulation |
| Type | Tool | Purpose |
|---|---|---|
| Unit | cargo test | Pure logic |
| Sync | nether run --sync-test | Runtime determinism |
| Replay | --record/--replay | Cross-build validation |
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
