community spotlight: april 2026 bernstein contributors

First time doing one of these. April was the first full month after going public, the diff between v1.0.0 and v1.8.8, and a number of those releases shipped with someone else's commits in them.

what landed

  • Architecture decomposition. The 4,198-line orchestrator broken into 22 focused sub-packages, each under 600 lines. Story is in the decomposition post.
  • Eighteen adapters. Started at seven, ended the month at eighteen: Claude Code, Codex, Gemini CLI, OpenAI Agents SDK, Cursor, Aider, Amp, Kiro, Kilo, Qwen, Goose, Ollama, Cody, Continue, OpenCode, Cloudflare Agents, IaC, generic. ~200 lines apiece.
  • Cost-aware routing. Bandit router cut spend roughly in half on internal runs.
  • Cloud execution. Cloudflare backend: Workers, Durable Workflows, R2, D1.
  • Windows support. Real Windows, not a footnote: env passthrough, Unicode, process management, terminal handling. Done by @oldschoola.
