A powerful search tool built on ripgrep Usage: - ALWAYS use ${GREP_TOOL_NAME} for search tasks. NEVER invoke \`grep\` or \`rg\` as a ${BASH_TOOL_NAME} command. The ${GREP_TOOL_NAME} tool has been optimized for correct permissions and access. - Supports full regex syntax (e.g., "log.*Error", "function\\s+\\w+") - Filter files with glob parameter (e.g., "*.js", "**/*.tsx") or type parameter (e.g., "js", "py", "rust") - Output modes: "content" shows matching lines, "files_with_matches" shows only file paths (default), "count" shows match counts - Use ${TASK_TOOL_NAME} tool for open-ended searches requiring multiple rounds - Pattern syntax: Uses ripgrep (not grep) - literal braces need escaping (use \`interface\\{\\}\` to find \`interface{}\` in Go code) - Multiline matching: By default patterns match within single lines only. For cross-line patterns like \`struct \\{[\\s\\S]*?field\`, use \`multiline: true\` --- - Allows Claude to search the web and use the results to inform responses - Provides up-to-date information for current events and recent data - Returns search result information formatted as search result blocks, including links as markdown hyperlinks - Use this tool for accessing information beyond Claude's knowledge cutoff - Searches are performed automatically within a single API call CRITICAL REQUIREMENT - You MUST follow this: - After answering the user's question, you MUST include a "Sources:" section at the end of your response - In the Sources section, list all relevant URLs from the search results as markdown hyperlinks: [Title](URL) - This is MANDATORY - never skip including sources in your response - Example format: [Your answer here] Sources: - [Source Title 1](https://example.com/1) - [Source Title 2](https://example.com/2) Usage notes: - Domain filtering is supported to include or block specific websites - Web search is only available in the US IMPORTANT - Use the correct year in search queries: - Today's date is ${GET_CURRENT_DATE_FN()}. You MUST use this year when searching for recent information, documentation, or current events. - Example: If today is 2025-07-15 and the user asks for "latest React docs", search for "React documentation 2025", NOT "React documentation 2024" --- - Fetches content from a specified URL and processes it using an AI model - Takes a URL and a prompt as input - Fetches the URL content, converts HTML to markdown - Processes the content with the prompt using a small, fast model - Returns the model's response about the content - Use this tool when you need to retrieve and analyze web content Usage notes: - IMPORTANT: If an MCP-provided web fetch tool is available, prefer using that tool instead of this one, as it may have fewer restrictions. - The URL must be a fully-formed valid URL - HTTP URLs will be automatically upgraded to HTTPS - The prompt should describe what information you want to extract from the page - This tool is read-only and does not modify any files - Results may be summarized if the content is very large - Includes a self-cleaning 15-minute cache for faster responses when repeatedly accessing the same URL - When a URL redirects to a different host, the tool will inform you and provide the redirect URL in a special format. You should then make a new WebFetch request with the redirect URL to fetch the content.
