Using Determinism and Replay | Agent Skills Atlas

About this skill

Use when designing a system whose past behaviour must be recoverable as a fact — RL training substrates, multi-agent simulations, deterministic game engines, replay-debuggable services, multiplayer lockstep, or any pipeline where "I cannot reproduce that bug" is unacceptable. Use when teams disagree about what "snapshot", "seed", or "replay" mean across modules. Use when cross-machine or cross-process determinism is required, or a regulator will ask "what was the input at tick T?". Architecture-level — how to design a deterministic system. For verifying an existing simulation against known patterns, use /check-determinism from yzmir-simulation-foundations instead.

Original description

Use when designing a system whose past behaviour must be recoverable as a fact — RL training substrates, multi-agent simulations, deterministic game engines, replay-debuggable services, multiplayer lockstep, or any pipeline where "I cannot reproduce that bug" is unacceptable. Use when teams disagree about what "snapshot", "seed", or "replay" mean across modules. Use when cross-machine or cross-process determinism is required, or a regulator will ask "what was the input at tick T?". Architecture-level — how to design a deterministic system. For verifying an existing simulation against known patterns, use `/check-determinism` from yzmir-simulation-foundations instead.
