Autocomplete functionality missing for @Docs directory and subdirectories

Environment

• Platform (select one):
• [x] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 1.0.63
• Operating System: Linux 5.15.146.1-microsoft-standard-WSL2
• Terminal: WSL2

## Bug Description
Claude Code's autocomplete functionality does not work for files located in the @Docs directory or
any of its subdirectories. When attempting to reference files using the @ syntax (e.g.,
@Docs/CODEBASE.md), the autocomplete does not suggest any files from the Docs folder, making it
difficult to quickly reference documentation files.

## Steps to Reproduce

1. Open Claude Code in a project that contains a Docs/ directory with markdown files
2. Type @Docs/ in the chat interface
3. Observe that no autocomplete suggestions appear for files within the Docs directory
4. Compare with other directories (e.g., @Source/ or @Plugins/) which do show autocomplete

suggestions

## Expected Behavior
When typing @Docs/, Claude Code should show autocomplete suggestions for all files within the Docs
directory and its subdirectories, including:

• @Docs/CODEBASE.md
• @Docs/UI.md
• @Docs/AbilitySystem.md
• @Docs/Plans/BuildWarnings-TODO.md
• etc.

## Actual Behavior
No autocomplete suggestions appear when typing @Docs/ or attempting to reference any files within
the Docs directory structure. The autocomplete feature appears to be completely disabled for this
directory.

## Additional Context

• The Docs directory contains 15+ markdown files and subdirectories that would benefit from

autocomplete

• Other directories in the same project (Source, Plugins, etc.) do show proper autocomplete

functionality

• This affects productivity when trying to quickly reference documentation files during development

discussions

• Project structure shows Docs directory is at root level: /mnt/e/Projects/App/Docs/
