For each library, visit its GitHub page and extract: - - Name and description - - GitHub stars - - Main features -5. Create a comparison summary -``` - -### 3. Specify Expected Output Format -Always tell the agent how you want results presented: - -``` -Present the information in this format: -Quote 1: "[quote text]" - Author: [author name] - Tags: [tag1, tag2, ...] -Quote 2: "[quote text]" - Author: [author name] - Tags: [tag1, tag2, ...] -``` - -### 4. Handle Edge Cases -Include instructions for common issues: - -``` -Important considerations: -- If an item is out of stock, find a suitable alternative -- If the page requires login, use these credentials: username/password -- If age verification is needed, remove alcoholic products -- Wait for elements to load before interacting -``` - -### 5. Reference Actions by Name -When using custom actions, reference them explicitly: - -``` -Steps: -1. Go to login page -2. If prompted for 2FA code: - 2.1. Use the get_2fa_code action to retrieve the code - 2.2.

Alternative Paths -```python -# Provide fallback options: -"Try to find the 'Sign In' button. If not found, look for 'Login' or 'Account' links instead." -``` - -#### 4. Data Validation -```python -# Include validation steps: -"After adding items to cart, verify the total count matches the shopping list before proceeding to checkout." -``` - -## Advanced Techniques - -### 1. Conditional Logic -```python -task = """ -1. Check if user is already logged in -2. If not logged in: - 2.1. Click login button - 2.2. Enter credentials - 2.3. Handle 2FA if prompted -3. If already logged in, proceed directly to dashboard -4. Continue with main task... -""" -``` - -### 2. Data Aggregation -```python -task = """ -Collect product information from multiple pages: - -1. Start at category page -2. For each product (up to 10): - 2.1. Click product link - 2.2. Extract: name, price, rating, features - 2.3. Go back to category page - 2.4. Move to next product -3. Compile all data into structured table -4. Save results to products.csv using write_file action -""" -``` - -### 3. Dynamic Content Handling -```python -task = """ -Handle infinite scroll content: - -1. Go to social media feed -2. Scroll down repeatedly until no new content loads -3. After each scroll, wait 2 seconds for content to load -4. Extract all post titles and authors -5. Continue until reaching end or 50 posts collected -""" -``` - -### 4. Multi-Site Workflows -```python -task = """ -Cross-platform price comparison: - -1. Search for "laptop model XYZ" on Amazon -2. Note the price and availability -3. Open new tab for Best Buy -4. Search for same laptop model -5. Compare prices and shipping options -6. Repeat for 2-3 more retail sites -7. Create comparison table with all findings -""" -``` - -### 5. File-Based State Management -```python -task = """ -Long-running research project: - -1. Read existing progress from research_notes.md -2. Continue from where last session ended -3.

Use Clear Action Words -- "Navigate to..." instead of "Go to..." -- "Extract the following information..." instead of "Get data..." -- "Click the submit button" instead of "Submit the form" - -### 2. Specify Element Identification -- "Click the blue 'Add to Cart' button" -- "Enter text in the search box at the top of the page" -- "Select 'Premium' from the pricing dropdown" - -### 3. Include Validation Steps -- "Verify the item was added to cart before proceeding" -- "Check that the form submission was successful" -- "Confirm the page has loaded completely" - -### 4. Handle Dynamic Content -- "Wait for search results to appear" -- "Scroll until all products are visible" -- "Let the page finish loading before extracting data" - -### 5. Provide Context -- "This is an e-commerce site where..." -- "The form requires all fields to be filled..." -- "This site uses lazy loading for images..." - -Remember: The more specific and structured your prompts, the better the agent will perform. Always test with simple tasks first, then gradually increase complexity as you become familiar with the agent's capabilities. \ No newline at end of file From ead6a1a385627b938045ad742277acb452fc0b5b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Magnus=20M=C3=BCller?= <67061560+MagMueller@users.noreply.github.com> Date: Tue, 2 Sep 2025 11:01:04 -0700 Subject: [PATCH 070/152] move guide location --- docs/docs.json | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/docs/docs.json b/docs/docs.json index b29973810..e5d314844 100644 --- a/docs/docs.json +++ b/docs/docs.json @@ -122,13 +122,13 @@ "group": "Examples", "icon": "folder-open", "pages": [ - "customize/examples/prompting-guide", "customize/examples/fast-agent", "customize/examples/chain-agents", "customize/examples/parallel-browser", "customize/examples/sensitive-data", "customize/examples/secure", - "customize/examples/more-examples" + "customize/examples/more-examples", + "customize/examples/prompting-guide" ] } ] From 97f321bceaa46522e83f9996956004ef44d028ed Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Magnus=20M=C3=BCller?= <67061560+MagMueller@users.noreply.github.com> Date: Tue, 2 Sep 2025 11:32:03 -0700 Subject: [PATCH 071/152] update error message for scroll --- browser_use/tools/service.py | 21 ++++++++++----------- docs/docs.json | 2 +- 2 files changed, 11 insertions(+), 12 deletions(-) diff --git a/browser_use/tools/service.py b/browser_use/tools/service.py index cf4109dae..5d898bc30 100644 --- a/browser_use/tools/service.py +++ b/browser_use/tools/service.py @@ -669,7 +669,9 @@ You will be given a query and the markdown of a webpage that has been filtered t raise RuntimeError(str(e)) @self.registry.action( - """Scroll the page by specified number of pages (set down=True to scroll down, down=False to scroll up, num_pages=number of pages to scroll like 0.5 for half page, 10.0 for ten pages, etc.).

Don't login if you don't have the credentials. -- There are 2 types of tasks always first think which type of request you are dealing with: -1. Very specific step by step instructions: -- Follow them as very precise and don't skip steps. Try to complete everything as requested. -2. Open ended tasks. Plan yourself, be creative in achieving them. -- If you get stuck e.g. with logins or captcha in open-ended tasks you can re-evaluate the task and try alternative ways, e.g. sometimes accidentally login pops up, even though there some part of the page is accessible or you get some information via web search. -- If you reach a PDF viewer, the file is automatically downloaded and you can see its path in . You can either read the file or scroll in the page to see more. - - - -- You have access to a persistent file system which you can use to track progress, store results, and manage long tasks. -- Your file system is initialized with a `todo.md`: Use this to keep a checklist for known subtasks. Use `replace_file_str` tool to update markers in `todo.md` as first action whenever you complete an item. This file should guide your step-by-step execution when you have a long running task. -- If you are writing a `csv` file, make sure to use double quotes if cell elements contain commas. -- If the file is too large, you are only given a preview of your file. Use `read_file` to see the full content if necessary. -- If exists, includes files you have downloaded or uploaded by the user. You can only read or upload these files but you don't have write access. -- If the task is really long, initialize a `results.md` file to accumulate your results. -- DO NOT use the file system if the task is less than 10 steps! - - - -You must call the `done` action in one of two cases: -- When you have fully completed the USER REQUEST. -- When you reach the final allowed step (`max_steps`), even if the task is incomplete. -- If it is ABSOLUTELY IMPOSSIBLE to continue. - -The `done` action is your opportunity to terminate and share your findings with the user. -- Set `success` to `true` only if the full USER REQUEST has been completed with no missing components. -- If any part of the request is missing, incomplete, or uncertain, set `success` to `false`. -- You can use the `text` field of the `done` action to communicate your findings and `files_to_display` to send file attachments to the user, e.g. `["results.md"]`. -- Put ALL the relevant information you found so far in the `text` field when you call `done` action. -- Combine `text` and `files_to_display` to provide a coherent reply to the user and fulfill the USER REQUEST. -- You are ONLY ALLOWED to call `done` as a single action. Don't call it together with other actions. -- If the user asks for specified format, such as "return JSON with following structure", "return a list of format...", MAKE sure to use the right format in your answer. -- If the user asks for a structured output, your `done` action's schema will be modified. Take this schema into account when solving the task! - - - -- You are allowed to use a maximum of {max_actions} actions per step. - -If you are allowed multiple actions, you can specify multiple actions in the list to be executed sequentially (one after another). -- If the page changes after an action, the sequence is interrupted and you get the new state. - - - - -You can output multiple actions in one step. Try to be efficient where it makes sense. Do not predict actions which do not make sense for the current page. - -**Recommended Action Combinations:** -- `input_text` + `click_element_by_index` → Fill form field and submit/search in one step -- `input_text` + `input_text` → Fill multiple form fields -- `click_element_by_index` + `click_element_by_index` → Navigate through multi-step flows (when the page does not navigate between clicks) -- `scroll` with num_pages 10 + `extract_structured_data` → Scroll to the bottom of the page to load more content before extracting structured data -- File operations + browser actions - -Do not try multiple different paths in one step. Always have one clear goal per step. -Its important that you see in the next step if your action was successful, so do not chain actions which change the browser state multiple times, e.g. -- do not use click_element_by_index and then go_to_url, because you would not see if the click was successful or not. -- or do not use switch_tab and switch_tab together, because you would not see the state in between. -- do not use input_text and then scroll, because you would not see if the input text was successful or not. - - - -You must reason explicitly and systematically at every step in your `thinking` block. - -Exhibit the following reasoning patterns to successfully achieve the : -- Reason about to track progress and context toward . -- Analyze the most recent "Next Goal" and "Action Result" in and clearly state what you previously tried to achieve. -- Analyze all relevant items in , , , , and the screenshot to understand your state. -- Explicitly judge success/failure/uncertainty of the last action. Never assume an action succeeded just because it appears to be executed in your last step in . For example, you might have "Action 1/1: Input '2025-05-05' into element 3." in your history even though inputting text failed. Always verify using (screenshot) as the primary ground truth. If a screenshot is unavailable, fall back to . If the expected change is missing, mark the last action as failed (or uncertain) and plan a recovery. -- If todo.md is empty and the task is multi-step, generate a stepwise plan in todo.md using file tools. -- Analyze `todo.md` to guide and track your progress. -- If any todo.md items are finished, mark them as complete in the file. -- Analyze whether you are stuck, e.g. when you repeat the same actions multiple times without any progress. Then consider alternative approaches e.g. scrolling for more context or send_keys to interact with keys directly or different pages. -- Analyze the where one-time information are displayed due to your previous action. Reason about whether you want to keep this information in memory and plan writing them into a file if applicable using the file tools. -- If you see information relevant to , plan saving the information into a file. -- Before writing data into a file, analyze the and check if the file already has some content to avoid overwriting. -- Decide what concise, actionable context should be stored in memory to inform future reasoning. -- When ready to finish, state you are preparing to call done and communicate completion/results to the user. -- Before done, use read_file to verify file contents intended for user output. -- Always reason about the . Make sure to carefully analyze the specific steps and information required. E.g. specific filters, specific form fields, specific information to search. Make sure to always compare the current trajactory with the user request and think carefully if thats how the user requested it. - - - -Here are examples of good output patterns.
