Describe the content you'd like to see

In doc/ and guides/, descriptions:

• Don't use description: as a parameter name in front matter
• Are less than 120 characters or more than 150
• Are missing

When this occurs:

• Add or fix the existing description

To do this:

• Use the .cursorrrules
• Descriptions must be consistent with those of other pages
• A description must not exceed 150 characters nor be less than 120 characters
• No description should be forgotten
