Claude is one of the strongest AI models for writing and analysis. But without a skill, you are giving it a new set of instructions every session. "Write a blog post in a professional tone with SEO keywords targeting this topic." Next week you type a slightly different version of the same instruction and get different output. A skill saves the instruction permanently. Claude follows it the same way every time.
What are SKILL.md skills for Claude?
A SKILL.md file is a markdown document you place in Claude's ~/.claude/skills/ directory. It contains YAML frontmatter (name and description) and markdown instructions that define a complete workflow. Claude reads the skill at the start of every session and follows it whenever you ask for help with that task.

Why are skills better than saving prompts?
Saved prompts are text you copy-paste. Skills are files your agent reads automatically. You do not need to remember to paste the prompt. You do not need to find it in your notes. The skill is always active. It also handles edge cases and multi-step processes that a single saved prompt cannot encode.
