CLI works locally but fails in CI: do you check env or versions first?

Compares environment-variable checks versus version checks for CLI failures in CI.

For CLI failures that only happen in CI, I usually compare environment variables, working directory, tool version, and config file path before changing the command. The same command can mean something different if CI lacks a cached login, runs from another folder, or has a different runtime. Which comparison do you make first when the local command succeeds but the CI log fails?
