During April 2026, Jescalan enhanced webhook delivery reliability for the NousResearch/hermes-agent repository by focusing on backend development and robust error handling using Python. Jescalan addressed issues with intermittent loss of final webhook responses by replacing delivery_info.pop() with .get(), ensuring delivery configurations persisted across multiple sends for the same chat ID. To improve memory efficiency and scalability, Jescalan implemented a TTL-based cleanup mechanism that prunes outdated delivery_info entries, preventing unbounded memory growth. The work demonstrated a thoughtful approach to API integration and testing, resulting in more stable end-to-end webhook delivery and a maintainable, scalable backend infrastructure.
