How to Stop Shipping Low-Quality RL Environments with Examples

How to Stop Shipping Low-Quality RL Environments (with Examples)

Auriel W argues that RL environments act as data generators, lists five harness failure classes including stale cache and reward hacks, and says teams should fix the harness first when the environment failure rate exceeds 5%.

Why it matters: This Latent Space tutorial clears HKR-H/K/R with a concrete harness-quality angle, 5 failure modes, and a >5% fix-first threshold. It is useful agent/RL engineering signal, but not a same-day must-write release.
