Prompt

Create a UiPath Flow project named "ReadingList" that curates a reading list
from a catalog of math and data science books.

The catalog is this inline JSON array (hardcode it in the flow, no input variables):

[
  {"title": "Linear Algebra Done Right", "author": "Axler", "field": "math", "difficulty": 6, "pages": 340},
  {"title": "Deep Learning", "author": "Goodfellow", "field": "ml", "difficulty": 9, "pages": 800},
  {"title": "Statistical Learning", "author": "James", "field": "data science", "difficulty": 4, "pages": 440},
  {"title": "Elements of Statistical Learning", "author": "Hastie", "field": "stats", "difficulty": 9, "pages": 745},
  {"title": "Bayesian Data Analysis", "author": "Gelman", "field": "stats", "difficulty": 8, "pages": 580},
  {"title": "Python for Data Analysis", "author": "McKinney", "field": "data science", "difficulty": 3, "pages": 550},
  {"title": "Probability Theory", "author": "Jaynes", "field": "math", "difficulty": 10, "pages": 753},
  {"title": "Information Theory", "author": "MacKay", "field": "ml", "difficulty": 7, "pages": 540}
]

The flow should:
1. Filter to books with difficulty greater than 5 AND under 600 pages
2. Transform the results to show only the book title (uppercased) and author
3. Output the curated reading list as a result variable

Use transform nodes for the data operations, not script nodes.

Do NOT run flow debug — just validate the flow.
Do NOT ask for approval, confirmation, or feedback. Do NOT pause between planning and implementation. Build the complete flow end-to-end in a single pass.
Before starting, load the uipath-maestro-flow skill. Read and follow its workflow steps exactly.
