Worked on the pydantic/pydantic-ai repository to streamline dependency management and reduce build complexity. Focused on cleaning up the pyproject.toml file by removing the redundant fasta2a dependency, which was already included in the project's extras. This targeted change addressed potential conflicts in installation and continuous integration environments, helping to maintain compatibility with supported configurations. Utilized skills in dependency management and configuration file editing, specifically working with TOML. The update improved repository hygiene and reduced maintenance overhead, ensuring that dependency declarations remained concise and aligned with project requirements. The work emphasized careful, incremental improvements rather than introducing new features.
