AGENTS.md not read in worktree agents

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

AGENTS.md not read in worktree agents by default. It works if I add a Cursor rule saying “always read AGENTS.md”. AGENTS.md is always read by default in local agents.

Steps to Reproduce

have an AGENTS.md that instructs the agent to greet you in a quirky way. Load a worktree agent and ask it to print the number of LOC in the current repo.

Expected Behavior

AGENTS.md read from all session types

Operating System

MacOS
