GitHub Commit

Your task is to stage all current changes, generate a structured and concise commit message based on those changes, and then perform the git commit.

First, stage all changes in the current directory using the `git add .` command.

After staging, analyze the staged changes to understand the modifications by reviewing the output of `git diff --staged`.

Based on this analysis, generate a commit message with the following structure:
1.  **Subject Line:** A short and concise summary of the changes.
2.  **Body:** A brief description of the changes, explaining the 'what' and 'why'. This should be a maximum of one or two sentences.

Ensure there is a blank line between the subject and the body.

Finally, construct and execute the `git commit` command using the generated subject and body. Do not push the commit to the remote repository.

Your final output should be ONLY the sequence of commands to stage the files and then commit them.
