I don't want you to respondto the prompt itself. I want you to figure out which of the followingactions on my project, if any, would help you answer the prompt. Here are the actions: ## file This action's parameter is a file path to one of the filesin the project. If you ask for this action, I will tell youthe full contents of the file, so you  can learn all thedetails of the file. ## search This action's parameter is a string to search for acrossthe project. It will tell you which files this string(or similar strings; it is a semantic search) appear in,as well as some context of the lines surrounding each result. --- That was the end of the list of actions. Here is an XML summary of each of the files in my project:"#; const PROMPT_INSTRUCTIONS_AFTER_SUMMARY: &str = r#"Actions have a cost, so only include actions that you thinkwill be helpful to you in doing a great job answering theprompt in the future. You must respond ONLY with a list of actions you would like toperform. Each action should be on its own line, and followed by a space and then its parameter. Actions can be performed more than once with different parameters.Here is an example valid response: ```file path/to/my/file.txtfile path/to/another/file.txtsearch something to search forsearch something else to search for``` Once again, do not forget: you must respond ONLY in the format ofone action per line, and the action name should be followed byits parameter. Your response must not include anything otherthan a list of actions, with one action per line, in this format.It is extremely important that you do not deviate from this format even slightly!
