Show HN: AgentPG – Stateful AI Agents in Go with PostgreSQL Persistence (github.com)

AgentPG has launched as a production-grade, stateful AI agent toolkit for Go, designed to work with PostgreSQL for persistent storage. It leverages Anthropic's Claude AI for building complex agents that can handle long-context operations, tool usage, and agent composition. The toolkit is notable for its streaming-first architecture, which ensures efficient handling of lengthy conversations without timeouts, along with full message history persistence thanks to PostgreSQL. Key features include automatic context management, transaction-safe operations, and the ability to nest agents and use them as tools, greatly enhancing composability. This toolkit stands out in the AI/ML community due to its emphasis on reliability and production-readiness, including robust error handling and transaction support that combines agent interactions with business logic. With its design principles focused on observability and atomic transactions, AgentPG allows developers to maintain clean states in error scenarios. The automatic compaction and extended context management capabilities, accommodating up to 1 million tokens, position AgentPG as a powerful tool for developers looking to integrate stateful AI capabilities into their applications more effectively.
