unerr

To make a coding agent work well on real code, you end up bolting a bunch of separate things onto it — one to find the right code, one to stop it forgetting, one to trim the clutter, your rules, a few checks to catch mistakes. You set them all up, you keep them running, and it still ignores half of them — because each one is only advice it can skip, and they all pull at its attention at once.

unerr puts all of that into one piece, built into the way the agent already works — so it's not one more thing the agent can choose to ignore. As the agent goes, it finds the right code, keeps your rules in front of it, trims the clutter, and catches a break before it lands — all together, with nothing for you to set up. The agent wastes less time, money, and attention redoing work, and you waste less of yours setting tools up and cleaning up after it.
