 The file uses `.gitignore` syntax. Only files that match a pattern and are also gitignored are copied, so tracked files are never duplicated.
 
+If you write a pattern that starts with `**/` and the files you want are inside a directory that is gitignored as a whole, Claude Code copies them only when that directory itself matches the pattern, or when the first name after the `**/` is one of the names in the directory's path. For example, if you write `**/.claude/skills/*.md`, that first name is `.claude`, so Claude Code copies the matching files out of an ignored `.claude/` directory. To copy files out of an ignored directory that a `**/` pattern doesn't reach, name the directory in the pattern instead: write `vendor/**/config.json` rather than `**/config.json`. Before v2.1.239, Claude Code copied files out of a wholly ignored directory for a `**/` pattern only when the directory itself matched the pattern.

 This `.worktreeinclude` copies two env files and a secrets config into each new worktree:
