Worked on the mastra-ai/mastra repository to address a critical issue in the AgentVoice.speak API, focusing on client-server payload alignment. Using TypeScript and client-side development skills, updated the client code to send a 'text' field instead of 'input' in the JSON body, ensuring compatibility with the server contract and the generateSpeechBodySchema. This fix improved the reliability of speech generation and user voice interactions by eliminating payload errors. Collaborated closely with team members through co-authored commits and documented the patch release, providing clear rationale for the changes and supporting ongoing API integration and maintenance efforts within the project.
