Inside Coding Agents: What Survives Between Sessions

AI Native Netherlands is back! We'll be hosting our 14th edition at the Xebia office in Amsterdam, and this is our last meetup of the year. First, a thank you. We've just passed 2,000 members, which makes this one of the biggest AI engineering communities in the Netherlands! A huge thank you to our friends at Xebia for hosting us and providing food and drinks. This is the second time Xebia has had us over, the OGs among you will remember the early editions. We'll cover: What a coding agent actually stores during a session, and what survives context compaction The difference between session history and persistent memory, and why the two get confused How Claude Code handles memory, with focused contrasts from Codex and Pi How a correct observation turns harmful once its original scope is lost Practical principles for deciding what gets loaded automatically, reviewed regularly, or retrieved only when needed Speaker 1: Vladislav Ramazaev (BlueDolphin) Vlad is a Senior Software Engineer at BlueDolphin with 10+ years of experience in architecture and system design, across distributed systems, data pipelines and high-load services in C/.NET, Kotlin and TypeScript. At BlueDolphin, he works on the microservices behind an enterprise architecture SaaS platform. Previously, he built data pipelines for AI model training and evaluation and led architecture and delivery practices across multiple engineering teams. Talk: Inside Coding Agents: What Survives Between Sessions Your coding agent can recover a decision from months ago, but did it actually remember it? This technical talk goes inside real coding-agent sessions to examine what gets stored, what survives context compaction, and what the model can access later. Using Claude Code as the main example, with focused contrasts from Codex and Pi, we'll separate session history from persistent memory and see how a correct observation can become harmful when its original scope is lost. You'll leave with a clearer model of agent memory and practical principles for deciding what should be loaded automatically, reviewed regularly, or retrieved only when needed. Speaker 2: To be confirmed by Xebia. Agenda: 18:00 — Arrival, food & drinks 18:45 — Talk 1 | Vladislav Ramazaev (BlueDolphin) 19:30 — Talk 2 | To be confirmed 20:15 — Open conversation, networking & more drinks 21:00 — Wrapping up What to bring: Just curiosity and your own questions. If you're running agents day to day and fighting context limits, memory files, or agents that confidently repeat something that stopped being true three sprints ago, bring that. Who this is for: Software engineers, platform and AI engineers, architects, and engineering leaders working with coding agents in real codebases. Where to find us: Xebia, Wibautstraat 200, 1091 TJ Amsterdam — Google Maps Link One last thing: Since this is our final edition of the year, come and close it out with us. Thank you for a great year, enjoy the holidays, and we'll see you at the end of January for the first meetup of 2027.
