alt Hacker News> It's basically just a way for the LLM to lazy-load curated information, tools, and scripts into context.
So basically a reusable prompt like the previous has asked?

Yes, but with more sales magic sprinkled on top.
Ah not exactly.
The way the OP phrased it
> Is a skill essentially a reusable prompt that is inserted at the start of any query?
Actually is a more apt description for a different Claude Code feature called Slash Commands
Where I can create a preset "prompt" and call it with /name-of-my-prompt $ARGS
and this feature is the one that essentially prefixes a Prompt.
The other description of lazy loading is more accurate for Skills.
Where I can tell my Claude Code system: Hey if you need to run our dev server see my-dev-server-skill
and the agent will determine when to pull in that skill if it needs it.
