I definitely see the value and versatility of Claude Skills (over what MCP is today), but I find the sandboxed execution to be painfully inefficient.
Even if we expect the LLMs to fully resolve the task, it'll heavily rely on I/O and print statements sprinkled across the execution trace to get the job done.

sandbox is not mandatory here. You can execute the skills on your host machine too (with some fidgeting) but it's a good practice and probably for the better to get in to the habit of executing code in an isolated environment for security purposes.
