OB-1 is a terminal-based coding agent — like Claude Code, but with multi-model access and self-optimizing workflows. You bring your own API keys (or use ours), pick the best model for each task, and let OB-1 handle the rest. Creates evaluation suites from past PRs, then climbs them. Every commit raises the bar for the next one. Generates hooks, rules, and reusable skills from your codebase and session history. Gets sharper with every interaction. Safe sandboxed agents that keep working while you context-switch. Spawn exploration, planning, and execution in parallel. Fork any conversation for parallel exploration. Share sessions with a link so teammates can continue with full context. Never runs out of ideas. OB-1 proactively suggests next steps, identifies friction points, and plans entire workstreams autonomously. Every conversation thread produces a fully-contextualized pull request. Reviewers see the reasoning, not just the diff. Slack, Linear, GitHub, Graphite. OB-1 embeds directly into your workflow. No context-switching. Delegate tasks as they come to mind.
