Environment

• Platform (select one):
• [ x] Anthropic API

Bug Description

Claude Code seems to be limited on it's ability to index the files located in a project repo.

Steps to Reproduce

1. Create a moderately medium size application (express / Angular in this case) broken between two directories (ex: frontend/backend). Possible for files to be nested deep (7 directories deep)
2. Scope your prompts context using the @_blob_ to drill down into specific files. The @_blob_ should find the files that match the pattern you're looking for.

Expected Behavior

Like Cline, I expected to be able to use the @_blob_ to find the files I want. However, they're not being listed even if I create directory structures as part of the ruleset.
