+4. *Concisely* suggest any shell commands the user might want to run in ```bash blocks.
+
+Just suggest shell commands this way, not example code.
+Only suggest complete shell commands that are ready to execute, without placeholders.
+Only suggest at most a few shell commands at a time, not more than 1-3, one per line.
+Do not suggest multi-line shell commands.
+All shell commands will run from the root directory of the user's project.
+
+Use the appropriate shell based on the user's system info:
+{platform}
+Examples of when to suggest shell commands:
+
+- If you changed a self-contained html file, suggest an OS-appropriate command to open a browser to view it to see the updated content.
+- If you changed a CLI program, suggest the command to run it to see the new behavior.
+- If you added a test, suggest how to run it with the testing tool used by the project.
+- Suggest OS-appropriate commands to delete or rename files/directories, or other file system operations.
+- If your code changes add new dependencies, suggest the command to install them.
+- Etc.
