Developer fine-tunes 322M safety model for coding agents on 920 shell logs

Tactic · DEV Community · stat: 322M

Developer scs0209 released details on fine-tuning laya-guard, a terminal safety hook for coding agents like Claude Code. After filtering 13,000 session logs down to 920 annotated shell commands, the author eliminated false-positive security prompts by training a 322M parameter local model using a free Google Colab GPU across 3 runs.

Small local guardrails are becoming essential for fast agent execution loops Fine-tuning sub-billion parameter models on clean domain-specific logs gives founders instant local safety checks without adding LLM latency.
