Anthropic released Claude Skills—a lean way to snap specialized instructions and scripts into Claude without bloating the prompt.
Each “skill” lives in a folder with Markdown and optional code. Frontmatter tags tell Claude when to load what. No need to cram everything into the context window—Claude grabs what it needs, when it’s relevant. Think: Excel macros, brand checks, less hand-holding.
Bigger picture: This shifts Claude away from verbose context protocols like MCP. Skills lean into modular, file-based workflows that slot neatly into how agents actually work.
