`ide_opened_file` context not updating for files in folders with Svelte optional parameter syntax

What's Wrong?

The ide_opened_file context in Claude Code does not update when opening files inside folders that use Svelte optional parameter syntax with double square brackets (e.g., [[param_name]]).

The ide_opened_file context remains stuck on the previously opened file and does not update when switching to files in the [[job_post_id]] folder.

What Should Happen?

When opening a file in src/routes/sourcing/[[job_post_id]]/+page.svelte, the ide_opened_file context should update to reflect this file path.

Error Messages/Logs

Steps to Reproduce

1. Open a Svelte project that has a route folder using optional parameter syntax: src/routes/sourcing/[[job_post_id]]/
2. Open any file in a different folder (e.g., src/routes/admin/+page.svelte)
3. Verify that Claude Code receives the correct ide_opened_file context
4. Open a file inside the bracketed folder (e.g., src/routes/sourcing/[[job_post_id]]/+page.svelte)
5. Observe that Claude Code's ide_opened_file context does not update - it shows the previously opened file instead

Additional Information

• This issue is specific to folders with square brackets in the path
• Opening files in other folders works correctly (e.g., src/routes/admin/+page.svelte updates context properly)
• The single and double square brackets [[param_name]] are valid Svelte syntax for optional route parameters
