Project skills vanish from slash menu after moving a chat into a worktree

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

If I tag a project skill with / before creating a worktree, that skill stops showing up in the slash menu once the chat is running in the worktree. Plugin skills still appear. The skill files are present in the worktree on disk.

This also affects the agent: the skill is missing from the available-skills list injected into the session, so the model cannot discover it either.

Steps to Reproduce

Open an agent chat against a local repo that has project skills.
Type / and confirm a project skill appears in the autocomplete.
Move the chat into a new worktree (Worktree environment).
In that worktree chat, type / again and search for the same skill.

Expected Behavior

Project skills stay available in the slash menu and in the agent skill catalog after the chat moves into a worktree.

Additional Information

Repro’d by tagging a project skill in a local chat, then creating a worktree for that chat. After the move, / autocomplete only shows unrelated plugin skills for the same query. Typing the full skill name also does not surface it.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Attach the skill with @ (.cursor/skills/<name>/SKILL.md). It’s on disk in the worktree, so that works even when / doesn’t list it. Also worth trying Reload Window inside the worktree, then checking / again. If you can say whether the skill comes back after that (or stays missing), that helps narrow it.

What got fixed in the earlier thread was rules. Project skills in worktrees are still an issue we’re tracking, and it isn’t something in your setup. No timeline yet; I’ll post here when there’s an update.
