[microsoft/vscode] Copilot context is filled up by Tool Results after reading changed files

### ROOT CAUSE The issue arises because the Copilot agent is processing and generating Tool Results for LaTeX build files (e.g., `.aux`, `.log`, `.bbl`, etc.), which are not directly relevant to the user's coding tasks. These files are included in the workspace indexing, leading to verbose Tool Results that quickly consume the context window. This behavior is exacerbated in LaTeX projects due to the prevalence of such build files. ### CODE FIX To resolve this, configure Copilot to exclude LaTeX build files from workspace indexing. This prevents the generation of unnecessary Tool Results and avoids filling the context window. **Steps to fix:** 1. Open VS Code settings (`Ctrl+Shift+P` > `Settings`). 2. Search for `copilot.workspace.exclude`. 3. Add patterns for LaTeX build files (e.g., `**/*.aux`, `**/*.log`, `**/*.bbl`, etc.) to the exclude list. - Example configuration in `settings.json`: ```json "copilot.workspace.exclude": [ "**/*.aux", "**/*.log", "**/*.bbl", "**/*.blg" ] ``` 4. Save the changes and restart Copilot if necessary. This ensures Copilot focuses only on `.tex` files and other relevant code, maintaining context efficiency.
