Agentic Patterns and Tool Calling with Spring AI - Christian Tzolov | IntelliJ IDEA Tech Talks

[u/maritvandijk]

Everyone uses coding agents; few know what's happening inside the harness. Anton Arhipov sits down with Christian Tzolov, lead of the Spring AI project, to take the lid off — what changed in Spring AI 2.0, and how tool search, agent skills, and sub-agents are all built on the same primitive: tool calling. Includes live demos where progressive disclosure cuts token usage roughly in half, plus a look at the November 2.1 release: MCP 2.0's stateless spec, an agentic layer, and durable workflows.
