Skill Isolation Tester
Validates Claude Code skills in isolated environments like Git worktrees, Docker containers, or VMs to ensure portability and catch environment-specific bugs before public release.
The source repository doesn't declare a license. Check its terms before reusing the code.
Key features
- Production-ready test templates for APIs, file manipulation, and Git operations
- Risk-based auto-detection to recommend the appropriate isolation level based on skill behavior
- Automated side-effect monitoring to detect leftover files or orphaned processes
- Multi-environment isolation support including Git Worktree, Docker, and Virtual Machines
- Comprehensive test reports featuring performance analysis and readiness grading
Use cases
- Testing high-risk skills that perform system changes in a safe, disposable environment
- Validating a newly developed skill for hidden local dependencies before public release
- Verifying that complex skills correctly clean up temporary files and processes
FAQ
When should I use this skill?
Use it proactively before committing or publicly releasing any new Claude Code skill. It is specifically designed to verify that your skill works in a 'clean' environment and cleans up after itself without leaving orphaned processes or temporary files.
What capabilities does it provide for CI/CD workflows?
The skill includes production-ready test templates (like docker-skill-test-json.sh) that support JSON and JUnit output, making it easy to integrate automated skill validation into your existing CI/CD pipelines.
What does the Skill Isolation Tester do?
It automates the validation of Claude Code skills by running them in isolated environments like Git worktrees, Docker containers, or Virtual Machines. This ensures your skills are portable and free from environment-specific bugs or hidden dependencies before you share them.
Does this skill replace functional unit testing?
No, this skill focuses on environment portability, side-effect monitoring, and dependency validation. You should continue to use your standard testing framework for functional logic, while using this tool to ensure the skill survives deployment to other systems.
How does the risk-based auto-detection work?
The skill analyzes your code's behavior to recommend the safest isolation level. Low-risk, read-only skills are tested in fast Git worktrees, while high-risk skills that modify system configurations are automatically routed to full Virtual Machine isolation.
