Play the recording: When CI Shouts Back: LLMs in the OVS CI Pipeline

  • Why: Not networking — but a clear signal of where core infrastructure projects are heading: LLM-assisted code review inside the OVS CI pipeline, with the friction reported honestly rather than sold.
  • What: Experiments with CodeRabbit, Sourcery, and Claude SONNET-class models on OVS patch review. Findings: PR-based bot workflows fragment patch discussion into a second venue, branches must be kept very tightly in sync, and bots contradict themselves between runs ("suggest doing one thing then doing another"). A custom Claude-based reviewer (RFC on patchwork) offers own prompts, developer-runnable execution, and GitHub Actions integration — at real dollar cost.
  • How: PW-CI infrastructure changes plus custom prompting instead of SaaS review bots.
  • Where applicable: OVS CI specifically, but the lessons (bot consistency, cost, review-venue splitting) generalize to any patch-based OSS project evaluating review bots.
