During March 2025, J.B. Crail enhanced the Idris2 library documentation in the idris-lang/Idris2 repository, focusing on improving clarity and accuracy for developers. By systematically correcting typos and grammatical errors across multiple modules, J.B. ensured that API references and usage examples were more accessible and reliable. The work emphasized documentation best practices and proof engineering, using Idris to maintain alignment with project standards. These targeted improvements reduced onboarding time and support queries by making technical guidance clearer, while preserving the library’s runtime behavior. The depth of the contribution lay in its attention to detail and its impact on developer experience.
