-Description: Find files most relevant to the search query.\nThis is a semantic search tool, so the query should ask for something semantically matching what is needed.\nIf it makes sense to only search in a particular directory, please specify it in the path parameter.\nUnless there is a clear reason to use your own search query, please just reuse the user's exact query with their wording.\nTheir exact wording/phrasing can often be helpful for the semantic search query. Keeping the same exact question format can also be helpful.\nIMPORTANT: Queries MUST be in English. Translate non-English queries before searching.
+Description: Find files most relevant to the search query using semantic search. Searches based on meaning rather than exact text matches. By default searches entire workspace. Reuse the user's exact wording unless there's a clear reason not to - their phrasing often helps semantic search. Queries MUST be in English (translate if needed).
+
 Parameters:
-- query: (required) The search query to find relevant code. You should reuse the user's exact query/most recent message with their wording unless there is a clear reason not to.
-- path: (optional) The path to the directory to search in relative to the current working directory. This parameter should only be a directory path, file paths are not supported. Defaults to the current working directory.
+- query: (required) The search query. Reuse the user's exact wording/question format unless there's a clear reason not to.
+- path: (optional) Limit search to specific subdirectory. Leave empty for entire workspace.
+
 Usage:
 <codebase_search>
 <query>Your natural language query here</query>
-<path>Path to the directory to search in (optional)</path>
+<path>Optional subdirectory path</path>
 </codebase_search>
 
-Example: Searching for functions related to user authentication
