What
Claude Code now has a warning for task files. It says a task's files were written by the task's agent, that their contents should be treated as untrusted, and that instructions found in them should not be followed.
Why
This guards against prompt injection, where text in a file tries to give Claude orders. Instructions written into a task file should not change what Claude does.
