Summary
Anthropic’s engineering post introducing Agent Skills: organized folders of instructions, scripts and resources that an agent discovers and loads dynamically, built around a required SKILL.md file whose YAML frontmatter carries a name and description. It presents progressive disclosure as the format’s core design principle — metadata pre-loaded into the system prompt, the SKILL.md body read on trigger, and bundled files navigated only as needed — and works the arrangement through the PDF skill behind Claude’s document-editing abilities, including a bundled script the model runs without loading it into context. It closes with authoring guidance (start from evaluation, split for scale, attend to name and description, iterate with the model), a warning to audit skills from less-trusted sources, and stated intentions to explore complementing MCP servers and to let agents author their own Skills.
