Cheikh Gueye Wane enhanced the BLSQ/openhexa-toolbox repository by refining its documentation to improve developer onboarding and API usage clarity. He focused on aligning usage examples with recent codebase changes, specifically renaming the hexa_client variable to hexa for consistency and updating GraphQL documentation to include pagination variables such as page and perPage for workspace data fetching. Using Markdown and Python, Cheikh applied code refactoring and documentation skills to ensure the documentation accurately reflected the latest API updates. His work addressed potential confusion for new users, reducing support queries and making the OpenHEXA toolbox more accessible and maintainable for developers.
