TALKS

• "Testing LLM Agent Conversations with rspec-agents" by Frederik Fix

LLM-based agents present unique challenges in terms of validation. The indeterminacy of their outputs makes it impossible to use traditional deterministic assertions. This talk presents the rspec-agents plugin that uses simulated conversations along with rubric-based checks to evaluate the performance of these agents.

• "429 Too Many Pull Requests" by Henning Koch

Coding agents made work trivial to start and hard to finish. The bottleneck has moved to the one resource that didn't scale: an experienced human who has to read the diff and sign off on it. This talk is about reviewing less and understanding more: a workflow where pull requests contain no surprises and every diff I read is worth my time.
