Summary

We have a package in our org that we import as a git repo source into our other repos. In our package code I symlinked AGENTS.md to .github/copilot-instructions.md as we use the Codex coding agent and GitHub Copilot. The issue was in the uv cache for our package all . prefixed folders were excluded (so no .github directory) which left my AGENTS.md as a dangling symlink. Which didn't cause any issues until I tried to run uv cache clean which errored with an os error.

I now know not to symlink to files in . prefixed directories like this... although I do wonder if uv could've handled this issue more gracefully.
