Identify shell and launch mode. Inspect only needed $nu paths, including loginshell-path, vendor-autoload-dirs, and user-autoload-dirs.
Trace loaded files and generators before editing startup warnings; fix the owner, not generated output.
Check help source, help use, and help run before changing invocation. They are not interchangeable with nu script.nu.
Treat $ans as REPL state, not a script result store. Preserve typed signatures and error paths.
# Configuration and scripts
1. Identify shell and launch mode. Inspect only needed `$nu` paths, including `loginshell-path`, `vendor-autoload-dirs`, and `user-autoload-dirs`.
2. Trace loaded files and generators before editing startup warnings; fix the owner, not generated output.
3. Check `help source`, `help use`, and `help run` before changing invocation. They are not interchangeable with `nu script.nu`.
4. Treat `$ans` as REPL state, not a script result store. Preserve typed signatures and error paths.
