Creating or improving a Claude Code Skill is difficult because the description must trigger at the right times, while the body must provide clear, cold-start instructions in the correct plugin folder structure.
Use the new-skill workflow to create a new Skill by asking Claude to make a skill for "X" and writing SKILL.md to match the system’s progressive disclosure and trigger-accuracy requirements.

To create a Claude Code Skill that triggers reliably, you must write a YAML frontmatter description that accurately matches user intents and structure the plugin folder with clear cold-start instructions inside SKILL.md.
Progressive disclosure in a Claude plugin structure involves keeping SKILL.md focused on core instructions while moving deeper detail into references, scripts, and assets folders using an explicit resource manifest.
You test YAML trigger evaluation by using the bundled eval infrastructure to validate trigger behavior, which checks whether the skill description actually causes Claude to invoke it and allows for iterating improvements.
You structure skill folders for a Claude Code plugin by creating a root SKILL.md file and managing on-demand resources like references, scripts, and assets in separate subdirectories according to plugin conventions.
A Claude Skill fails to trigger when its YAML frontmatter description does not accurately match user requests, requiring a trigger-accuracy optimization loop to refine the description and validate behavior.
Yes, you can use automation scripts within a Claude Code Skill by placing them in the scripts directory and declaring them in the resource manifest to ensure they load correctly during execution.
