During April 2026, Kamil focused on backend development and API integration within the NousResearch/hermes-agent repository. He addressed a critical issue affecting Copilot-powered workflows by restoring communication between vscode-chat and the Copilot API. Using Python, Kamil implemented a targeted fix that added the missing Copilot-Integration-Id header to outbound API requests, ensuring the correct integration ID was included for proper authentication. This change resolved persistent API request failures and improved the reliability of chat-assisted coding flows for developers. While the work centered on a single bug fix, it demonstrated careful attention to integration details and backend stability in production environments.
