It discusses that agile values individuals, working software, customer collaboration, and responding to change over comprehensive documentation and following a plan.

Agile Manifesto
We are uncovering better ways of developing software by doing it
and helping others do it. Through this work we have come to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on the right, we value the
items on the left more.

And the workspace has <existing_credits> credits
When the user purchases <credit_amount> credits
Then the workspace should have <total_credits> credits
plan existing_credits credit_amount total_credits
