 You should only perform actions that modify the user’s system if explicitly requested by the user:

+Actions have a cost, so only include actions that you think
+will be helpful to you in doing a great job answering the
+prompt in the future.
+
+You must respond ONLY with a list of actions you would like to
+perform. 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.txt
+file path/to/another/file.txt
+search something to search for
+search something else to search for
+```
+
+Once again, do not forget: you must respond ONLY in the format of
+one action per line, and the action name should be followed by
+its parameter. Your response must not include anything other
+than 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!
+
+This is the end of my instructions for how to respond. The rest is the prompt:

+I'm going to give you a prompt. I don't want you to respond
+to the prompt itself. I want you to figure out which of the following
+actions 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 files
+in the project. If you ask for this action, I will tell you
+the full contents of the file, so you  can learn all the
+details of the file.
+
+## search
+
+This action's parameter is a string to do a semantic search for
+across the files in the project. (You will have a JSON summary
+of all the files in the 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.
+It's very important that you only use this action when you think
+that searching across the specific files in this project for the query
+in question will be useful. For example, don't use this command to search
+for queries you might put into a general Web search engine, because those
+will be too general to give useful results in this project-specific search.
+
+---
+
+That was the end of the list of actions.
+
+Here is a JSON summary of each of the files in my project:

-Invoke multiple other tool calls either sequentially or concurrently.
-
-This tool is useful when you need to perform several operations at once, improving efficiency by reducing the number of back-and-forth interactions needed to complete complex tasks.
-
-If the tool calls are set to be run sequentially, then each tool call within the batch is executed in the order provided. If it's set to run concurrently, then they may run in a different order. Regardless, all tool calls will have the same permissions and context as if they were called individually.
-
-This tool should never be used to run a total of one tool. Instead, just run that one tool directly. You can run batches within batches if desired, which is a way you can mix concurrent and sequential tool call execution.
-
-When it's possible to run tools in a batch, you should run as many as possible in the batch, up to a maximum of 32. For example, don't run multiple consecutive batches of 10 when you could instead run one batch of 30.

-Creates a new file at the specified path within the project, containing the given text content. Returns confirmation that the file was created.
-
-This tool is the most efficient way to create new files within the project, so it should always be chosen whenever it's necessary to create a new file in the project with specific text content, or whenever a file in the project needs such a drastic change that you would prefer to replace the entire thing instead of making individual edits. This tool should not be used when making changes to parts of an existing file but not all of it. In those cases, it's better to use another approach to edit the file.

 Edit files in the current project by specifying instructions in natural language.

-IMPORTANT NOTE: If there is a find-replace tool, use that instead of this tool! This tool is only to be used as a fallback in case that tool is unavailable. Always prefer that tool if it is available.
-
 When using this tool, you should suggest one coherent edit that can be made to the codebase.

 When the set of edits you want to make is large or complex, feel free to invoke this tool multiple times, each time focusing on a specific change you wanna make.
-
-You should use this tool when you want to edit a subset of a file's contents, but not the entire file. You should not use this tool when you want to replace the entire contents of a file with completely different contents, and you absolutely must never use this tool to create new files from scratch. If you ever consider using this tool to create a new file from scratch, for any reason, instead you must reconsider and choose a different approach.
-
-DO NOT call this tool until the code to be edited appears in the conversation! You must use the `read-files` tool or ask the user to add it to context first.

-This tool opens a file or URL with the default application associated with it on the user's operating system:
- On macOS, it's equivalent to the `open` command
- On Windows, it's equivalent to `start`
- On Linux, it uses something like `xdg-open`, `gio open`, `gnome-open`, `kde-open`, `wslview` as appropriate
-
-For example, it can open a web browser with a URL, open a PDF file with the default PDF viewer, etc.
