Skills written entirely by the model are useless, and stacking skills taxes agent context

HamelHusain · x · 2026-10-26

Hamel Husain amplifies a discussion on agent skills: a skill written entirely by the model with no human input is one you don't need — value comes from injected domain knowledge. On whether consuming many skills in one session dirties context, dexhorthy's take: 5 steps in a single session is fine; you only need subagents/compaction when skills must stack (earlier instructions still honored later) or hundreds of skills must stay active, since each skill takes a share of attention.
