The Bot Runs as You: Hardening a ⚕ Hermes Agent for Guests | My Personal View to the World

MEMORY.md Is a Budget, Not a Document | My Personal View to the World

Why MEMORY.md is a budget of prompt space rather than a document: the four harnesses, what each caps, who enforces it, and when not to build one at all.

The Rules, Not the Words: ASD-STE100 for Agent Instructions | My Personal View to the World
