    • Agents performs degrade as repo size grows, because at that size (1M LOC =~10M tokens, well past any context window) it can only sample a fraction of the files.

    • 🚨 Just shipped dupehound: a Rust CLI that finds the code your AI wrote twice. Agents don't know what already exists in a codebase, so they rewrite it. Offline, no AI and open source.
