What Makes an AI Skill Different from a Prompt?

Most teams treat AI skills as saved prompt templates. They're not. A proper Skill is a capability contract—with input schemas, tool bindings, validation, and retry logic. Here's what that distinction means for production system design.

Why Does AI Forget What You Said Earlier?

Chat with an AI long enough and it ignores the rules you set up top; open a new chat and it's blank. It isn't 'forgetting' — it has no memory. Every reply, it re-reads the whole conversation from scratch. Here's what the context window is, and how it differs from ChatGPT's 'memory' feature.

為什麼 AI 會忘記我前面說過的話？

跟 AI 聊久了，它就忘記你開頭交代的事；開新對話更是整個忘光。其實它不是「忘記」，是它根本沒有記憶——每次回你都是把整段對話重讀一遍。用一個失憶但讀很快的人的畫面，聊聊 context window 是什麼，還有它跟 ChatGPT 那個「記憶」功能差在哪。

The Skill Your Annoyed Prompt Becomes

Your first Claude Code skill won't look like the polished examples in tutorials. It'll look like a prompt you've typed three times in a row, saved into a four-line markdown file. This post walks that minimum shape, shows the three things that break, and compares it to a real seventeen-line production-grade skill from the framework I use daily.

What a 13-Line Skill Leaves Out

I asked Claude to draft me a skill that calls OpenAI's Codex CLI. It came back as thirteen lines of markdown. The thirteen lines aren't the skill — they point to where the skill actually lives. That split between dispatcher and contract is what separates a skill from a prompt.
