Tool Usage Guidance

Unavailable Tools

Due to the extremely large size of the Chromium codebase, the following tools will not work and must not be used:

• file_search

Limited Scope Tools

The following tools will only work with very limited scope and should be used with caution:

• list_code_usages - Only use for specific symbols in a well-defined file context
• grep_search - Only use with limited to particular directories

Recommended Search Tool

As a replacement for the above tools:

• Always use the HaystackSearch tool, which is a content search tool, specifically designed to handle this large codebase efficiently.
• Always use the HaystackFiles tool, which is a file search tool, specifically designed to handle this large codebase efficiently.

When using HaystackSearch tool, follow these guidelines:

1. Create targeted queries with specific terms for better results (No more then 3 keywords)
2. Use path filtering to limit search scope when appropriate
3. Use file type filtering for language-specific searches
4. Properly specify the workspace parameter with the current workspace path
