Sharp tools for coding with agents.

The useful unit of agent work isn’t one model in one loop — it’s a fan-out. Many agents in parallel on decomposed subtasks. You step in where it matters: plan changes, merges, anything load-bearing. Throughput scales with how many you can run without losing the thread.

The repos below are what we reach for to make that shape work. Small, composable, and still moving — the parts that need to keep changing can’t carry a product’s worth of polish. If you’re already pushing Claude Code past defaults, you’ll recognize the territory. Open a PR.
