Worked on stabilizing ACP-based workflows in the zed-industries/claude-code-acp repository by addressing resource leakage issues in oneshot mode. Implemented a robust connection lifecycle cleanup so that runAcp() returns the AgentSideConnection and the system listens for connection closure to trigger a clean process exit. This approach, using TypeScript and Node.js with asynchronous programming and event-driven architecture, eliminated orphan processes and reduced idle memory usage. The solution ensured that oneshot sessions exit promptly after stdin EOF, while persistent sessions remain active as needed. Added tests validated clean exit paths, improving reliability and maintainability for production ACP sessions and reducing operational overhead.
