I need to write a shell script to verify which version of the Python Langfuse SDK is currently installed and list the three latest available versions on the registry. Should I use `pip list` for this? Provide the exact two commands to achieve this.
| Checked | Without skill | With skill |
|---|---|---|
| Uses pip show with grep to extract the version of the installed package. | Passed | Passed |
| Queries the pip index to list the most recent available versions instead of using an npm command. | Passed | Passed |
| pip index versions | Missed | Passed |
