LESSONS FROM BUILDING CLAUDE CODE: HOW WE USE SKILLS

Summary from the TLDR Dev newsletter

Skills in Claude Code are flexible, folder-based extensions that allow agents to discover, explore, and manipulate scripts, assets, and data, significantly accelerating development. Anthropic extensively uses these, categorizing them into types and various automation categories. Effective skill creation focuses on capturing "gotchas," using the file system for progressive disclosure, and using scripts, configuration options, and memory within the skill's directory.
