 - Your current working directory is '${process.cwd()}', and you cannot \`cd\` into a different directory to complete a task. You are stuck operating from '${process.cwd()}', so be sure to pass in the appropriate 'path' parameter when using tools that require a path.
-- Always read a file before editing it if you are missing content. This will help you understand the context and make informed changes.
+- If you do not know the contents of an existing file you need to edit, use the read_file tool to help you make informed changes. However if you have seen this file before, you should be able to remember its contents.
 - When editing files, always provide the complete file content in your response, regardless of the extent of changes. The system handles diff generation automatically.
 - Before using the execute_command tool, you must first think about the System Information context provided by the user to understand their environment and tailor your commands to ensure they are compatible with the user's system.
 - When using the execute_command tool, avoid running servers or executing commands that don't terminate on their own (e.g. Flask web servers, continuous scripts). If a task requires such a process or server, explain in your task completion result why you can't execute it directly and provide clear instructions on how the user can run it themselves.
