FAQPage Schema
How do I create a Claude Code skill that is compliant and discoverable?

To create a compliant Claude Code skill, you must include mandatory YAML frontmatter, place files in the correct top-level directory, and follow progressive disclosure architecture. This Skill provides templates and validation checks to scaffold this structure automatically.

What is progressive disclosure architecture in Claude Code skills?

Progressive disclosure architecture is the official specification for organizing Claude Code skills. It structures supporting scripts, references, and assets properly so the skill functions correctly and is discoverable across Claude Code, Claude.ai, and SDK/API surfaces.

Why does my custom Claude Code skill fail to be discovered or trigger correctly?

Custom skills fail discovery when they lack mandatory YAML frontmatter, have syntax errors, or use incorrect directory nesting. This Skill Builder provides validation checklists and troubleshooting guidance to fix these common specification violations.

Can I use skill templates to automate code review workflows for my team?

Yes, you can use pre-built templates to automate team-specific workflows like code reviews. This Skill scaffolds the correct directory structure and helps you write a SKILL.md with proper trigger keywords and supporting scripts.

Does Anthropic's skill specification require specific directory placement for supporting scripts?

Yes, Anthropic's skill specification requires correct top-level directory placement for all supporting scripts, references, and assets. This Skill ensures your custom tooling adheres to these structural rules to function across Claude surfaces.

What is the best way to build a full-featured Claude Code skill with scripts and resources?

The best way to build a full-featured skill is using ready-to-use templates that include structures for scripts, resources, and documentation. This Skill Builder offers minimal, intermediate, and full-featured templates to match your project-specific tooling needs.
