What environments does the sandbox support?

It currently supports two main tracks: Group A for Next.js/React applications and Group B for standalone Node.js or specialized utility environments.

What is a meta skill in Claude Code?

A meta skill is a specialized capability designed to manage, test, or orchestrate other skills rather than directly modifying application code. This skill acts as a CI/CD layer for your skill library.

Can it automatically fix broken skill documentation?

Yes, if a skill fails validation during the test loop, the agent analyzes the error, updates the SKILL.md file with the correct instructions or dependencies, and retries the implementation.

How does this skill handle complex dependencies?

It parses the frontmatter of every skill to build a dependency graph, detects cycles, and uses Kahn's algorithm to determine the exact order in which skills must be applied.

Does it provide a final report of the test results?

Yes, it generates a comprehensive report at test-results/report.md detailing the pass/fail status of every skill, the number of attempts, and any fixes applied.

セキュリティとテスト

Automates the integration testing and validation of the entire skill catalog through dependency-aware sandbox composition.

The Test All Skills meta-utility is a robust framework for ensuring the reliability and interoperability of a Claude Code skill library. It constructs a complex dependency graph to systematically apply skills within clean sandbox environments in topological order. By simulating real-world layered implementations, the skill identifies composition conflicts, automatically fixes markdown documentation, and validates the final build. This ensures that a collection of isolated AI capabilities functions as a cohesive, production-ready ecosystem.
