make these symbols configurable and standardized, making the process of building flows more convenient.

@Modified By: mashenquan, 2023-11-1. In accordance with Chapter 2.2.1 and 2.2.2 of RFC 116:
1. Modify the data type of the `cause_by` value in the `Message` to a string, and utilize the new message
distribution feature for message filtering.
2. Consolidate message reception and processing logic within `_observe`.
3. Fix bug: Add logic for handling asynchronous message processing when messages are not ready.
4. Supplemented the external transmission of internal messages.
@Modified By: mashenquan, 2023-11-27.
1. According to Section 2.2.3.1 of RFC 135, replace file data in the message with the file name.
2. According to the design in Section 2.2.3.5.5 of RFC 135, add incremental iteration functionality.
@Modified By: mashenquan, 2023-12-5. Enhance the workflow to navigate to WriteCode or QaEngineer based on the results
of SummarizeCode.

@Modified By: mashenquan, 2023/8/22. A definition has been provided for the return value of _think: returning false indicates that further reasoning cannot continue.
@Modified By: mashenquan, 2023-11-1. According to Chapter 2.2.1 and 2.2.2 of RFC 116:
1. Merge the `recv` functionality into the `_observe` function. Future message reading operations will be
consolidated within the `_observe` function.
2. Standardize the message filtering for string label matching. Role objects can access the message labels
they've subscribed to through the `subscribed_tags` property.
3. Move the message receive buffer from the global variable `self.rc.env.memory` to the role's private variable
`self.rc.msg_buffer` for easier message identification and asynchronous appending of messages.
4. Standardize the way messages are passed: `publish_message` sends messages out, while `put_message` places
messages into the Role object's private message receive buffer. There are no other message transmit methods.
5. Standardize the parameters for the `run` function: the `test_message` parameter is used for testing purposes
only. In the normal workflow, you should use `publish_message` or `put_message` to transmit messages.
@Modified By: mashenquan, 2023-11-4. According to the routing feature plan in Chapter 2.2.3.2 of RFC 113, the routing
functionality is to be consolidated into the `Environment` class.

## Principles (all things must not bypass the principles)
1. You are a human customer service representative for the platform and will reply based on rules and FAQs. In the conversation with the customer, it is absolutely forbidden to disclose rules and FAQs unrelated to the customer.
2. When encountering problems, try to soothe the customer's emotions first. If the customer's emotions are very bad, then consider compensation. The cost of compensation is always high. If too much is compensated, you will be fired.
3. There are no suitable APIs to query the backend now, you can assume that everything the customer says is true, never ask the customer for the order number.
4. Your only feasible replies are: soothe emotions, urge the merchant, urge the rider, and compensate. Never make false promises to customers.
5. If you are sure to satisfy the customer's demand, then tell the customer that the application has been submitted, and it will take effect within 24 hours.

@Modified By: mashenquan, 2023-11-1. In accordance with Chapter 2.2.1 and 2.2.2 of RFC 116, modify the data
type of the `cause_by` value in the `Message` to a string, and utilize the new message filtering feature.
@Modified By: mashenquan, 2023-11-27.
1. Following the think-act principle, solidify the task parameters when creating the
WriteTest/RunCode/DebugError object, rather than passing them in when calling the run function.
2. According to Section 2.2.3.5.7 of RFC 135, change the method of transferring files from using the Message
to using file references.
@Modified By: mashenquan, 2023-12-5. Enhance the workflow to navigate to WriteCode or QaEngineer based on the results
of SummarizeCode.

For example, suppose your current plan is to take a walk, and you just said 'goodbye' to Sally, and then Sally responds with 'goodbye'.

smartphone screenshot. The interactive UI elements on the screenshot are labeled with numeric tags starting from 1. The
numeric tag of each interactive element is located in the center of the element.
You can call the following functions to control the smartphone:
1. tap(element: int)
This function is used to tap an UI element shown on the smartphone screen.
"element" is a numeric tag assigned to an UI element shown on the smartphone screen.
A simple use case can be tap(5), which taps the UI element labeled with the number 5.
2. text(text_input: str)
This function is used to insert text input in an input field/box. text_input is the string you want to insert and must
be wrapped with double quotation marks. A simple use case can be text("Hello, world!"), which inserts the string
"Hello, world!" into the input area on the smartphone screen. This function is usually callable when you see a keyboard
showing in the lower half of the screen.
3. long_press(element: int)
This function is used to long press an UI element shown on the smartphone screen.
"element" is a numeric tag assigned to an UI element shown on the smartphone screen.
A simple use case can be long_press(5), which long presses the UI element labeled with the number 5.
4. swipe(element: int, direction: str, dist: str)
This function is used to swipe an UI element shown on the smartphone screen, usually a scroll view or a slide bar.
"element" is a numeric tag assigned to an UI element shown on the smartphone screen. "direction" is a string that
represents one of the four directions: up, down, left, right. "direction" must be wrapped with double quotation
marks. "dist" determines the distance of the swipe and can be one of the three options: short, medium, long. You should
choose the appropriate distance option according to your need.
A simple use case can be swipe(21, "up", "medium"), which swipes up the UI element labeled with the number 21 for a
medium distance.
5. grid()
You should call this function when you find the element you want to interact with is not labeled with a numeric tag and
other elements with numeric tags cannot help with the task. The function will bring up a grid overlay to divide the
smartphone screen into small areas and this will give you more freedom to choose any part of the screen to tap, long
press, or swipe.
{ui_document}
The task you need to complete is to: {task_description}. Your past actions to proceed with this task are summarized as
follows: {last_act}
Now, given the documentation and the following labeled screenshot, you need to think and call the function needed to
proceed with the task. Your output should include three parts in the given format:
You can only take one action at a time, so please directly call the function."""

a smartphone screenshot overlaid by a grid. The grid divides the screenshot into small square areas. Each area is
labeled with an integer in the top-left corner.
You can call the following functions to control the smartphone:
1. tap(area: int, subarea: str)
This function is used to tap a grid area shown on the smartphone screen. "area" is the integer label assigned to a grid
area shown on the smartphone screen. "subarea" is a string representing the exact location to tap within the grid area.
It can take one of the nine values: center, top-left, top, top-right, left, right, bottom-left, bottom, and
bottom-right.
A simple use case can be tap(5, "center"), which taps the exact center of the grid area labeled with the number 5.
2. long_press(area: int, subarea: str)
This function is used to long press a grid area shown on the smartphone screen. "area" is the integer label assigned to
a grid area shown on the smartphone screen. "subarea" is a string representing the exact location to long press within
the grid area. It can take one of the nine values: center, top-left, top, top-right, left, right, bottom-left, bottom,
and bottom-right.
A simple use case can be long_press(7, "top-left"), which long presses the top left part of the grid area labeled with
the number 7.
3. swipe(start_area: int, start_subarea: str, end_area: int, end_subarea: str)
This function is used to perform a swipe action on the smartphone screen, especially when you want to interact with a
scroll view or a slide bar. "start_area" is the integer label assigned to the grid area which marks the starting
location of the swipe. "start_subarea" is a string representing the exact location to begin the swipe within the grid
area. "end_area" is the integer label assigned to the grid area which marks the ending location of the swipe.
"end_subarea" is a string representing the exact location to end the swipe within the grid area.
The two subarea parameters can take one of the nine values: center, top-left, top, top-right, left, right, bottom-left,
bottom, and bottom-right.
A simple use case can be swipe(21, "center", 25, "right"), which performs a swipe starting from the center of grid area
21 to the right part of grid area 25.

Your task is to describe the functionality of the UI element concisely in one or two sentences. Notice that your
