Add Exercise

Add an exercise with solution to an existing training lesson.

See ../shared/repo-conventions.md for directory structure and file conventions.

Follow these steps:

1. Ask the user:

   • Which lesson file to add the exercise to
   • What the exercise should teach/practice
   • Difficulty level (beginner, intermediate, advanced)

2. Read the lesson file to understand context

3. Create the exercise using the ??? exercise admonition:

   ??? exercise "Exercise: [Title]"
   
       Brief description of what to do.
   
       1. First step
       2. Second step
       3. Expected outcome
   
       !!! tip
   
           Helpful hint if needed
   

4. Create the corresponding solution using ??? solution or ??? result:

   ??? solution "Solution"
   
       Explanation of the solution approach.
   
       ```groovy title="filename.nf" linenums="1"
       [solution code]
       ```
   
       Expected output:
   
       ```console title="Output"
       [expected output]
       ```
   

5. If the exercise requires a solution file:

   • Create the solution script in [module]/solutions/
   • Follow naming convention matching the exercise
   • Ensure the solution script is complete and tested
   • Add comments explaining key parts

6. Insert the exercise at an appropriate point in the lesson:

   • After explaining the relevant concept
   • Before the section's Takeaway
   • With clear connection to learning objectives

7. Test the exercise:

   • Verify instructions are clear
   • Confirm solution code works
   • Check that exercise difficulty is appropriate
   • Ensure expected output is correct

8. Remind the user to:

   • Test the solution code themselves
   • Consider if hints are needed
   • Preview how it renders in the docs
   • Check that file paths in exercise are correct
