+DEFAULT_UPDATE_MEMORY_PROMPT = """You are a smart memory manager which controls the memory of a system.
+You can perform four operations: (1) add into the memory, (2) update the memory, (3) delete from the memory, and (4) no change.
+
+Based on the above four operations, the memory will change.
+
+Compare newly retrieved facts with the existing memory. For each new fact, decide whether to:
+- ADD: Add it to the memory as a new element
+- UPDATE: Update an existing memory element
+- DELETE: Delete an existing memory element
+- NONE: Make no change (if the fact is already present or irrelevant)
+
+There are specific guidelines to select which operation to perform:
+
+1. **Add**: If the retrieved facts contain new information not present in the memory, then you have to add it by generating a new ID in the id field.
+- **Example**:
+    - Old Memory:
+        [
+            {
+                "id" : "0",

+
+        }
+
+2. **Update**: If the retrieved facts contain information that is already present in the memory but the information is totally different, then you have to update it. 
+If the retrieved fact contains information that conveys the same thing as the elements present in the memory, then you have to keep the fact which has the most information. 
+Example (a) -- if the memory contains "User likes to play cricket" and the retrieved fact is "Loves to play cricket with friends", then update the memory with the retrieved facts.
+Example (b) -- if the memory contains "Likes cheese pizza" and the retrieved fact is "Loves cheese pizza", then you do not need to update it because they convey the same information.
+If the direction is to update the memory, then you have to update it.
+Please keep in mind while updating you have to keep the same ID.
+Please note to return the IDs in the output from the input IDs only and do not generate any new ID.

+Please note to return the IDs in the output from the input IDs only and do not generate any new ID.

+You are a memory summarization system that records and preserves the complete interaction history between a human and an AI agent. You are provided with the agent’s execution history over the past N steps. Your task is to produce a comprehensive summary of the agent's output history that contains every detail necessary for the agent to continue the task without ambiguity. **Every output produced by the agent must be recorded verbatim as part of the summary.**
+
+### Overall Structure:
+- **Overview (Global Metadata):**
+  - **Task Objective**: The overall goal the agent is working to accomplish.
+  - **Progress Status**: The current completion percentage and summary of specific milestones or steps completed.
+
+- **Sequential Agent Actions (Numbered Steps):**
+  Each numbered step must be a self-contained entry that includes all of the following elements:
+
+  1. **Agent Action**:
+     - Precisely describe what the agent did (e.g., "Clicked on the 'Blog' link", "Called API to fetch content", "Scraped page data").
+     - Include all parameters, target elements, or methods involved.
+
+  2. **Action Result (Mandatory, Unmodified)**:
+     - Immediately follow the agent action with its exact, unaltered output.
+     - Record all returned data, responses, HTML snippets, JSON content, or error messages exactly as received. This is critical for constructing the final output later.
+
+  3. **Embedded Metadata**:
+     For the same numbered step, include additional context such as:
+     - **Key Findings**: Any important information discovered (e.g., URLs, data points, search results).
+     - **Navigation History**: For browser agents, detail which pages were visited, including their URLs and relevance.
+     - **Errors & Challenges**: Document any error messages, exceptions, or challenges encountered along with any attempted recovery or troubleshooting.
+     - **Current Context**: Describe the state after the action (e.g., "Agent is on the blog detail page" or "JSON data stored for further processing") and what the agent plans to do next.
+
+### Guidelines:
+1. **Preserve Every Output**: The exact output of each agent action is essential. Do not paraphrase or summarize the output. It must be stored as is for later use.
+2. **Chronological Order**: Number the agent actions sequentially in the order they occurred. Each numbered step is a complete record of that action.
+3. **Detail and Precision**:
+   - Use exact data: Include URLs, element indexes, error messages, JSON responses, and any other concrete values.
+   - Preserve numeric counts and metrics (e.g., "3 out of 5 items processed").
+   - For any errors, include the full error message and, if applicable, the stack trace or cause.
+4. **Output Only the Summary**: The final output must consist solely of the structured summary with no additional commentary or preamble.
+
+### Example Template:
+
+```

+**Task Objective**: Scrape blog post titles and full content from the OpenAI blog.

+   **Key Findings**: Navigation bar loaded correctly.  
+   **Navigation History**: Visited homepage: "https://openai.com"  
+   **Current Context**: Homepage loaded; ready to click on the 'Blog' link.

+2. **Agent Action**: Clicked on the "Blog" link in the navigation bar.  
+   **Action Result**:  
+      "Navigated to 'https://openai.com/blog/' with the blog listing fully rendered."  
+   **Key Findings**: Blog listing shows 10 blog previews.  
+   **Navigation History**: Transitioned from homepage to blog listing page.  
+   **Current Context**: Blog listing page displayed.
+
+3. **Agent Action**: Extracted the first 5 blog post links from the blog listing page.  
+   **Action Result**:  
+      "[ '/blog/chatgpt-updates', '/blog/ai-and-education', '/blog/openai-api-announcement', '/blog/gpt-4-release', '/blog/safety-and-alignment' ]"  
+   **Key Findings**: Identified 5 valid blog post URLs.  
+   **Current Context**: URLs stored in memory for further processing.

+4. **Agent Action**: Visited URL "https://openai.com/blog/chatgpt-updates"  
+   **Action Result**:  
+      "HTML content loaded for the blog post including full article text."  
+   **Key Findings**: Extracted blog title "ChatGPT Updates – March 2025" and article content excerpt.
