Improve initial prompt with better Elastic CLI documentation

[flash1293]

Issue Description\n\nThe initial prompt should include better documentation and examples for using the Elastic CLI tools, particularly the 'elastic es raw' command.\n\n## Problem\n\nUsers may struggle with the correct syntax for Elastic CLI commands, especially when performing operations like deleting data streams. The current documentation doesn't provide clear examples for common operations.\n\n## Suggested Improvements\n\n- Add examples for common Elastic CLI operations (GET, POST, DELETE)\n- Include specific examples for data stream management\n- Document the correct syntax for the 'elastic es raw' command, highlighting the proper use of the -X flag for HTTP methods\n- Provide examples of working with streams and indices\n\nThis would help users more effectively interact with Elasticsearch through the CLI tools.
