Improving our Java SDK with Codex by OpenAI

Codex, a new cloud-based software engineering agent developed by OpenAI, has proven to be a valuable tool for the Temporal team by efficiently addressing tasks such as bug fixing, feature implementation, and refactoring, which were previously time-consuming. Initially intended for usability feedback, Codex quickly became integral to Temporal's development workflow, helping to resolve longstanding issues in the Java SDK and enhancing code coverage and documentation. Codex operates in the background, allowing developers to continue local development while it handles multiple tasks in parallel, demonstrating its potential to streamline software engineering processes. Additionally, Temporal has optimized its projects for agentic contributions by creating AGENTS.md files to guide Codex in better interacting with the codebase. Codex's operational success is supported by Temporal's infrastructure, which provides the necessary reliability and scalability for its complex distributed systems. OpenAI acknowledges Temporal's role in enabling Codex to manage concurrency, correctness, and fault tolerance, which are essential for its efficient execution. As Codex continues to evolve, Temporal plans to further enhance their open-source projects for agentic contributions, inviting others to explore the capabilities of Codex and Temporal's infrastructure.
