Reward Hacking in Autonomous Agent Training
How Goodhart's Law and Skalse's unhackability theorems explain reward hacking in RL and LLM agents, and how consequence-based selection changes the loop.

Master anchored sft kl divergence fine tuning, combining probability-weighted loss with trust region sft lora and kl regularized supervised fine tuning.

Master experience replay catastrophic forgetting llm solutions with complementary learning systems and rehearsal buffer LoRA fine-tuning strategies.

Elastic Weight Consolidation (EWC) explained: how Fisher weight springs prevent catastrophic forgetting, why they struggle at LLM scale, and tools to try.

When an agent's actions alter its environment for good, cumulative replay causes catastrophic remembering; a sliding window sustains continual learning.

Afterlife is an open-source Agent Skill and CLI tool that lets local LLMs nominate memories, train and test LoRA adapters, and activate or roll back updates.
