  "response": "<think>\nOkay, let's tackle this problem. The task is to check if the police station in Pittsburgh can be reached in one hour by car from Gates Building at CMU. The user has provided annotation descriptions from four parts of a video and a Playwright action trace. I need to analyze all this data to summarize a complete user operation description that accomplishes the task, structured into strategies, substrategies, and actions with corresponding Playwright instructions.\n\nFirst, I'll start by understanding the objective. The user wants to determine the travel time by car between two specific locations: a police station in Pittsburgh and the Gates Hillman Center (Gates Building) at Carnegie Mellon University (CMU). The key here is to use OpenStreetMap's directions feature to get the driving time between these two points.\n\nLooking at the annotation descriptions:\n\nPart 1: The user searches for a police station on OpenStreetMap. They click the search box, type \"police station,\" click \"Go,\" and choose a specific station. However, the example here is Lopatcong Twp Police Station, which might not be in Pittsburgh. This might be an error, but perhaps in the actual process, the correct this later.\n\nPart 2: The user sets up the directions form, entering \"pittsburgh police\" in both From and To fields. They select \"Zone One Police Station, Jacksonia Street, Ca\" as the starting point. But the task requires starting from Gates Building, so this might be a misstep. However, in Part 4, they adjust the starting point to CMU.\n\nPart 3: The user is setting the destination. They first try \"gates hillman center\" but then change it to \"Carnegie Mellon University, Schenley Drive,\" which is likely the correct destination. Then, in Part 4, they reverse the directions, setting CMU as the starting point and the police station as the destination.\n\nWait, in Part 4, the user modifies the starting point to CMU and generates directions. So the correct flow would be to set From as CMU and To as the police station. But in Part 2, they initially set From as a police station, then in Part 3, To as Gates Hillman, then in Part 4, they change the From to CMU. So the process involves correcting the starting point.\n\nThe Playwright actions include clicking on the \"Find directions between two points\" link, interacting with the From and To text boxes, pressing Enter, and clicking the \"Reverse Directions\" button. The URLs don't change, which suggests all actions are on the same page, possibly the directions page.\n\nPutting this together, the user's process involved:\n\n1. Searching for a police station in Pittsburgh.\n2. Setting up directions with From as a police station and To as another, but then realizing the task requires starting from CMU.\n3. Correcting the From field to CMU and the To field to the police station.\n4. Generating the directions and checking the travel time.\n\nBut the exact steps need to be structured into strategies. Let's outline the strategies:\n\nStrategy 1: Search for the Pittsburgh Police Station on OpenStreetMap.\n- Substrategy: Use the search function to locate the police station.\n- Actions: Click search box, type \"police station,\" click Go, select the dropdown result.\n\nStrategy 2: Set up directions from CMU Gates Building to the Police Station.\n- Substrategy: Input starting point (CMU) and destination (police station).\n- Actions: Access directions feature, input From as CMU, To as police station, click Go.\n\nStrategy 3: Generate and review the route details.\n- Substrategy: Execute the route calculation and check travel time.\n- Actions: Click Go, view the directions, check the duration.\n\nBut looking at the Playwright actions, there's a \"Reverse Directions\" click (action_18), which might switch From and To. This could be part of correcting the direction.\n\nWait, in the annotations, Part 4 shows the user changing the From field to CMU and generating directions. So maybe the steps are:\n\n1. Search for the police station (Part 1).\n2. Open directions (Part 2 starts with directions form).\n3. Initially set From as a police station (Part 2), then To as another (but then correct To to CMU in Part 3, then reverse directions in Part 4 to set From as CMU and To as police station).\n\nSo the correct flow would involve:\n\n- Opening directions.\n- Inputting From as CMU (Gates Hillman Center or Carnegie Mellon University, Schenley Drive).\n- Inputting To as the desired Pittsburgh police station.\n- Generating the route and checking the time.\n\nBut the user's steps in the annotations show some back-and-forth, like initially setting From as a police station, then changing it. The Playwright trace includes a \"Reverse Directions\" action (action_18), which swaps From and To. So maybe after setting From as police and To as CMU, they reversed it to get From as CMU and To as police.\n\nSo the strategies would be:\n\nStrategy 1: Locate the Pittsburgh Police Station using Search.\nStrategy 2: Set up Directions from CMU to Police Station.\nStrategy 3: Generate and Review Route Details.\n\nBut how do the Playwright actions fit in? Let's map the actions.\n\nPlaywright actions include:\n\n- Clicking the search textbox (action_uid textbox_Search, idx 0)\n- Clicking \"Find directions between two points\" (link_Find directions..., idx 1)\n- Pressing Enter in the From textbox (idx 16)\n- Clicking somewhere (action_12, idx 12)\n- Pressing Enter in To textbox (idx 26)\n- Clicking Reverse Directions (action_18, idx 18)\n\nThe URLs are all the same, so the user is on the directions page after step 1.\n\nPutting this together, the user first searched for the police station, then went to directions, input From and To, possibly reversed them, and generated the route.\n\nBut the exact steps in the annotations have some inconsistencies. For example, in Part 2, they set both From and To as \"pittsburgh police\", which might be a mistake. Then in Part 3, they set To as Gates Hillman, then correct to CMU. Then in Part 4, they set From to CMU and generate the route.\n\nSo the correct sequence would be:\n\n1. Search for the police station to find its location (Part 1).\n2. Open the directions feature (Part 2's initial steps).\n3. Input From as CMU (Gates Building) and To as the police station (possibly using the Reverse Directions button if initially set the other way).\n4. Generate the route and check the time.\n\nNow, mapping the Playwright actions to these steps.\n\nThe Playwright action 0 is clicking the search textbox (Part 1). Then action 1 is clicking the \"Find directions\" link (Part 2). Then action 16 is pressing Enter in the From textbox (maybe after typing). Action 18 is Reverse Directions.\n\nThe annotations mention in Part 4 selecting CMU as the starting point and generating the route, which would correspond to the Reverse Directions click (action_18) to swap From and To.\n\nSo the strategies would be:\n\nStrategy 1: Search for the Pittsburgh Police Station.\n- Substrategy: Use the search bar to find the police station.\n- Actions: Click search box, type \"police station\", click Go, select the correct station from dropdown.\n\nStrategy 2: Access the Directions Feature.\n- Substrategy: Navigate to the directions form.\n- Action: Click \"Find directions between two points\" link.\n\nStrategy 3: Input Starting and Destination Points.\n- Substrategy: Set From as CMU Gates Building.\n- Actions: Click From textbox, type \"Carnegie Mellon University, Schenley Drive\", select from dropdown.\n\n- Substrategy: Set To as Pittsburgh Police Station.\n- Actions: Click To textbox, type police station name, select from dropdown.\n\nBut in the annotations, the user initially set From as a police station, then To as CMU, then reversed directions. So maybe:\n\nStrategy 3: Input Initial Route Points and Reverse.\n- Substrategy: Input From as Police Station and To as CMU.\n- Actions: Type into From and To fields, select from dropdowns.\n\n- Substrategy: Reverse the directions to set From as CMU.\n- Action: Click Reverse Directions button.\n\nStrategy 4: Generate and Review Route.\n- Substrategy: Execute the route calculation.\n- Action: Click Go button.\n- Substrategy: Check travel time.\n- Action: Scroll through directions to find duration.\n\nNow, mapping the Playwright actions to these steps.\n\nPlaywright action 0: Click search textbox (Part 1, step 1).\nPlaywright action 1: Click \"Find directions\" link (Part 2, step 1).\nPlaywright action 16: Press Enter in From textbox (maybe after typing \"pittsburgh police\").\nPlaywright action 12: Click on a locator related to the directions form (maybe selecting a dropdown item).\nPlaywright action 26: Press Enter in To textbox (after typing \"gates hillman\").\nPlaywright action 18: Click Reverse Directions (swapping From and To).\n\nSo the Reverse Directions action (action_18) is crucial here. After setting From as police and To as CMU, reversing them makes From CMU and To police.\n\nSo the final strategy would involve:\n\n1. Search for police station.\n2. Open directions.\n3. Input From as police, To as CMU.\n4. Reverse directions to get From as CMU, To as police.\n5. Generate route and check time.\n\nNow, compiling the JSON structure.\n\nThe strategies would be:\n\nStrategy 1: Search for the Pittsburgh Police Station.\nSubstrategies: Use search function.\nActions: Click search box (Playwright idx 0), type \"police station\", click Go, select from dropdown. But the Playwright actions here are idx 0 (click search) and maybe others. However, the Playwright trace for Part 1 includes actions 0 and 1 (click search and then directions link). Wait, the Playwright actions are a separate trace. Let's look at the Playwright actions provided.\n\nThe Playwright actions array has entries with idx from 0 to 26. For example, the first action is idx 0: clicking the search textbox. Then idx 1: clicking the \"Find directions\" link. Then idx 16: pressing Enter in the From textbox. Then idx 9: clicking some text. Then idx 12: clicking a locator. Then idx 26: pressing Enter in To. Then idx 18: reverse directions.\n\nBut the annotations describe multiple steps across four parts. The Playwright actions may not be in order, but the idx numbers might indicate the sequence. The idx values are 0,1,16,9,12,26,18. So the order is 0,1,9,12,16,18,26? Wait, the array is ordered as per the given JSON. Let me check:\n\nThe Playwright actions array is ordered as:\n\n[\n  { \"idx\": 0, ... },\n  { \"idx\": 1, ... },\n  { \"idx\": 16, ... },\n  { \"idx\": 9, ... },\n  { \"idx\": 12, ... },\n  { \"idx\": 26, ... },\n  { \"idx\": 18, ... }\n]\n\nWait, the actual order in the array is as listed, but the idx values are 0,1,16,9,12,26,18. So the sequence of actions as per their order in the array is idx 0,1,16,9,12,26,18. But this may not be chronological since idx might not be in order. However, the user probably performed actions in the order of the idx. For example, idx 0 comes first, then 1, then 16, etc. But this is unclear. However, the example output uses the idx as per the order in the array. So perhaps the idx is the step order. But the given array's idx values are 0,1,16,9,12,26,18. That's not in order. So maybe the idx is not the sequence. Alternatively, the actions are ordered in the array in the sequence they were performed. So the array's order is the actual sequence of actions. So the user first action is idx 0, then 1, then 16, then 9, then 12, then 26, then 18.\n\nBut this seems a bit messy. For example, after clicking the directions link (idx1), the next action is idx16 (pressing Enter in From textbox). Then idx9 (clicking some text), then idx12 (clicking a locator), then idx26 (pressing Enter in To), then idx18 (reverse directions).\n\nBut how does this align with the annotation parts?\n\nPart 1: Steps 1-4 (searching for police station) would correspond to Playwright actions 0 (click search) and maybe others, but after that, action 1 is directions link. So perhaps the user first searched for the police station (Part1), then clicked directions (action1), then proceeded to set up directions.\n\nBut the Playwright actions after action1 are 16,9,12,26,18. Let's see:\n\nAction 16: click From textbox and press Enter.\n\nAction9: clicking some text element (possibly a dropdown item).\n\nAction12: clicking a locator in the directions form.\n\nAction26: press Enter in To textbox.\n\nAction18: reverse directions.\n\nThis is a bit confusing. But the key is that the user used the Reverse Directions button (action18) which swaps From and To.\n\nPutting this all together, the final JSON should map the strategies and substrategies to the Playwright actions by their idx and action_repr.\n\nThe example output shows that each action in the JSON includes the playwright_idx and playwright_instruction.\n\nSo for each action in the strategy, we need to find the corresponding Playwright action from the trace.\n\nFor example, in Strategy 1: Search for Police Station.\n\nThe actions would be:\n\n- Click the search textbox (action_uid textbox_Search, idx0)\n- Type \"police station\"\n- Click Go (but in the Playwright trace, after clicking the search box, the next action is clicking the directions link (idx1), which might not be part of the search. Hmm, this is conflicting.\n\nWait, the Playwright actions for Part1 (searching) would be idx0 (click search box), then typing (not captured in Playwright actions?), then clicking Go (maybe not captured, unless there's a press Enter. But the Playwright actions provided don't show that. The Playwright actions provided are:\n\n[\n  { \"action_uid\": \"textbox_Search\", \"idx\": 0, \"action_repr\": \"frame.clickget_by_role(\\\"textbox\\\", name=\\\"Search\\\")\" },\n  { \"action_uid\": \"link_Find directions...\", \"idx\":1, ...},\n  { \"action_uid\": \"textbox_From\", \"idx\":16, ...},\n  { \"action_uid\": \"text_50 km...\", \"idx\":9, ...},\n  { \"action_uid\": \"action_12\", \"idx\":12, ...},\n  { \"action_uid\": \"textbox_To\", \"idx\":26, ...},\n  { \"action_uid\": \"action_18\", \"idx\":18, ...}\n]\n\nSo the user's first two actions are clicking the search box and then the directions link. The actual search for the police station (typing and clicking Go) might not be captured in the Playwright trace provided. This could mean that the Playwright trace is incomplete or that some actions are missing. However, the user's annotation descriptions include those steps, so we need to reconcile them.\n\nAlternatively, perhaps the Playwright trace is only a subset of actions, and the annotations include more detailed steps that aren't all present in the trace. In that case, we need to map as much as possible.\n\nBut according to the problem statement, we need to use the provided Playwright actions. So the JSON output should reference the Playwright actions by their idx and action_repr.\n\nGiven that, let's proceed.\n\nThe user's objective is to check travel time from CMU Gates to a police station.\n\nThe steps derived from annotations and Playwright actions:\n\n1. Search for police station (Part1) - but in Playwright, only idx0 (click search) and idx1 (directions link) are present. The actual search steps (typing, clicking Go) may not have corresponding Playwright actions here. So perhaps the Playwright trace is missing those, or maybe the user used the directions feature directly.\n\nBut according to the annotations, the user did search for the police station first. However, the Playwright actions after that are about directions. So perhaps the initial search is not captured in the Playwright trace beyond clicking the search box. But since the Playwright trace is given, we have to work with that.\n\nAlternatively, maybe the user first clicked the search box (idx0), then clicked the directions link (idx1), which is part of Strategy 2: Access Directions Feature.\n\nThen, in Strategy 3: Input From and To Points.\n\nBut the Playwright actions for inputting From and To are idx16 (press Enter in From), idx26 (press Enter in To), and idx18 (reverse directions).\n\nSo perhaps:\n\nStrategy 1: Access Directions Feature.\n- Substrategy: Open directions form.\n  - Action: Click \"Find directions between two points\" link (Playwright idx1).\n\nStrategy 2: Input Initial Route Points.\n- Substrategy: Set From as Police Station.\n  - Action: Press Enter in From textbox (idx16) after typing.\n- Substrategy: Set To as CMU.\n  - Action: Press Enter in To textbox (idx26) after typing.\n\nStrategy 3: Reverse Directions to Correct Start and End Points.\n- Substrategy: Swap From and To.\n  - Action: Click Reverse Directions button (idx18).\n\nStrategy 4: Generate and Review Route.\n- Substrategy: Execute route calculation.\n  - Action: Click Go button (possibly idx12 or others, but in Playwright actions, idx12 is a click on a locator in the directions form).\n\nBut this is getting a bit. Let's look at the annotations again.\n\nIn Part4, the user selects CMU as the starting point by selecting from the dropdown, then clicks Go. The Playwright action for this might be idx12 (clicking a locator in the directions form) and idx18 (reverse directions).\n\nAlternatively, the Reverse Directions button (action_18) swaps the From and To fields, which would correct the initial mistake of setting From as police and To as CMU.\n\nSo the correct steps would be:\n\n1. Open directions (idx1).\n2. Input From as police station (via idx16 press Enter).\n3. Input To as CMU (via idx26 press Enter).\n4. Reverse directions (idx18) to swap to From as CMU and To as police.\n5. Generate route (click Go, which might be idx12 or another action).\n\nBut the Playwright action idx12 is a click on a locator in the directions form. The action_repr is \"frame.clicklocator(\\\"#sidebar > .search_forms > .directions_form > div:nth-child(2) > .col\\\")\". This might be the Go button.\n\nSimilarly, idx9 is a click on some text element, which might be relevant.\n\nBut without more context, it's challenging. However, the example output requires mapping each action to the Playwright trace entries.\n\nSo, the final JSON should have strategies and actions with playwright_idx and playwright_instruction.\n\nPutting it all together:\n\nObjective: Check if the police station in Pittsburgh can be reached in one hour by car from Gates Building at CMU.\n\nStrategies:\n\n1. Access the Directions Feature on OpenStreetMap.\n   - Substrategy: Navigate to the directions form.\n     - Action: Click \"Find directions between two points\" link (Playwright idx1).\n\n2. Input Initial Route Points.\n   - Substrategy: Set From as a Police Station.\n     - Action: Press Enter in the \"From\" textbox after typing (Playwright idx16).\n   - Substrategy: Set To as CMU Gates Building.\n     - Action: Press Enter in the \"To\" textbox after typing (Playwright idx26).\n\n3. Correct Route Direction by Reversing Points.\n   - Substrategy: Swap From and To locations.\n     - Action: Click the \"Reverse Directions\" button (Playwright idx18).\n\n4. Generate and Review the Route.\n   - Substrategy: Execute the route calculation.\n     - Action: Click the \"Go\" button (Playwright idx12? Or another action. Looking at action_12: \"frame.clicklocator(\\\"#sidebar > .search_forms > .directions_form > div:nth-child(2) > .col\\\")\" — this might be the Go button. Or idx9, which is a click on text. But according to the annotations, after setting the destination, the user clicks Go, which updates the map. The Playwright action for that might be idx12 or idx9. However, the example in the problem's example uses the playwright_idx from the provided array. So need to check which action corresponds to clicking Go.\n\nIn the annotations, Part3 step3: clicking Go after typing \"gates hillman center\" — this would correspond to a Playwright action. In the provided trace, after typing in To (idx26 press Enter), the next action is idx18 (reverse), but maybe the Go button is action_12 or action_9.\n\nAlternatively, the \"Go\" button click might not be captured in the Playwright trace provided. But according to the annotations, the user did click Go multiple times. However, the Playwright actions provided don't have an explicit Go click except maybe idx12 or idx9.\n\nThis is a bit ambiguous, but given the data, we have to map as best as possible.\n\nFinal Observations:\n\n- The user reverses the directions to set From as CMU and To as police.\n- The final route's travel time is observed in the directions panel.\n\nKey Observations from Playwright Trace:\n\n- The Reverse Directions action (idx18) is critical to swapping the points.\n- The final URL remains the same, indicating all actions are on the directions page.\n\nNow, structuring the JSON:\n\nThe main strategies are:\n\n1. Access Directions Feature.\n2. Input Initial Route Points.\n3. Correct Route Direction.\n4. Generate and Review.\n\nEach with substrategies and actions referencing Playwright actions.\n\nThe JSON would look like:\n\n```json\n[\n  {\n    \"strategy\": \"Access Directions Feature\",\n    \"substrategies\": [\n      {\n        \"substrategy\": \"Navigate to Directions Form\",\n        \"actions\": [\n          {\n            \"description\": \"Click the 'Find directions between two points' link to open the directions form.\",\n            \"playwright_idx\": 1,\n            \"playwright_instruction\": \"frame.clickget_by_role(\\\"link\\\", name=\\\"Find directions between two points\\\")\"\n          }\n        ]\n      }\n    ]\n  },\n  {\n    \"strategy\": \"Input Initial Route Points\",\n    \"substrategies\": [\n      {\n        \"substrategy\": \"Set Starting Point as Police Station\",\n        \"actions\": [\n          {\n            \"description\": \"Press Enter in the 'From' textbox after typing 'pittsburgh police' to select the police station.\",\n            \"playwright_idx\": 16,\n            \"playwright_instruction\": \"frame.pressget_by_role(\\\"textbox\\\", name=\\\"From\\\")Enter\"\n          }\n        ]\n      },\n      {\n        \"substrategy\": \"Set Destination as CMU Gates Building\",\n        \"actions\": [\n          {\n            \"description\": \"Press Enter in the 'To' textbox after typing 'Carnegie Mellon University, Schenley Drive'.\",\n            \"playwright_idx\": 26,\n            \"playwright_instruction\": \"frame.pressget_by_role(\\\"textbox\\\", name=\\\"To\\\")Enter\"\n          }\n        ]\n      }\n    ]\n  },\n  {\n    \"strategy\": \"Correct Route Direction\",\n    \"substrategies\": [\n      {\n        \"substrategy\": \"Reverse Start and End Points\",\n        \"actions\": [\n          {\n            \"description\": \"Click the 'Reverse Directions' button to swap 'From' and 'To' locations.\",\n            \"playwright_idx\": 18,\n            \"playwright_instruction\": \"frame.clicklocator(\\\"#sidebar div\\\").filter(has_text=\\\"Reverse Directions\\\").nth(2)\"\n          }\n        ]\n      }\n    ]\n  },\n  {\n    \"strategy\": \"Generate and Review Route\",\n    \"substrategies\": [\n      {\n        \"substrategy\": \"Execute Route Calculation\",\n        \"actions\": [\n          {\n            \"description\": \"Click the 'Go' button to generate the route from CMU to the police station.\",\n            \"playwright_idx\": 12,\n            \"playwright_instruction\": \"frame.clicklocator(\\\"#sidebar > .search_forms > .directions_form > div:nth-child(2) > .col\\\")\"\n          }\n        ]\n      },\n      {\n        \"substrategy\": \"Check Travel Time\",\n        \"actions\": [\n          {\n            \"description\": \"Scroll through the directions panel to review the calculated travel duration.\",\n            \"playwright_idx\": null,\n            \"playwright_instruction\": \"Not captured in Playwright trace\"\n          }\n        ]\n      }\n    ]\n  }\n]\n```\n\nBut wait, the Playwright action idx12 is described as clicking a locator in the directions form. The example in the problem's sample output has some actions with playwright_idx and instruction. However, the Check Travel Time action may not have a corresponding Playwright action, so it's marked as not captured. But according to the problem statement, we need to include only actions present in the Playwright trace. So perhaps omit that action or note it's not present.\n\nAlternatively, since scrolling may not be captured as a Playwright action, it's not be included. So the Generate and Review strategy's substrategy \"Execute Route Calculation\" would have the Go button (idx12), and the Check Travel Time is part of the observation.\n\nBut according to the annotations, after clicking Go, the directions panel updates. The user then scrolls through the directions (Part4 step4), which is captured in the annotations but not in the Playwright trace. So in the JSON, we can include the action for clicking Go (idx12) but omit the scrolling if there's no corresponding Playwright action.\n\nThus, the final JSON would include the strategies and actions that have corresponding Playwright actions.\n</think>\n\n```json\n[\n  {\n    \"strategy\": \"Access Directions Feature\",\n    \"substrategies\": [\n      {\n        \"substrategy\": \"Open Directions Interface\",\n        \"actions\": [\n          {\n            \"description\": \"Click the 'Find directions between two points' link to initialize route planning.\",\n            \"playwright_idx\": 1,\n            \"playwright_instruction\": \"frame.clickget_by_role(\\\"link\\\", name=\\\"Find directions between two points\\\")\"\n          }\n        ]\n      }\n    ]\n  },\n  {\n    \"strategy\": \"Input Initial Route Points\",\n    \"substrategies\": [\n      {\n        \"substrategy\": \"Set Police Station as Starting Point\",\n        \"actions\": [\n          {\n            \"description\": \"Activate and populate the 'From' field with a Pittsburgh police station.\",\n            \"playwright_idx\": 16,\n            \"playwright_instruction\": \"frame.pressget_by_role(\\\"textbox\\\", name=\\\"From\\\")Enter\"\n          }\n        ]\n      },\n      {\n        \"substrategy\": \"Set CMU as Destination\",\n        \"actions\": [\n          {\n            \"description\": \"Activate and populate the 'To' field with Carnegie Mellon University's address.\",\n            \"playwright_idx\": 26,\n            \"playwright_instruction\": \"frame.pressget_by_role(\\\"textbox\\\", name=\\\"To\\\")Enter\"\n          }\n        ]\n      }\n    ]\n  },\n  {\n    \"strategy\": \"Correct Route Direction\",\n    \"substrategies\": [\n      {\n        \"substrategy\": \"Swap Start and End Points\",\n        \"actions\": [\n          {\n            \"description\": \"Reverse the 'From' and 'To' locations to prioritize CMU as the starting point.\",\n            \"playwright_idx\": 18,\n            \"playwright_instruction\": \"frame.clicklocator(\\\"#sidebar div\\\").filter(has_text=\\\"Reverse Directions\\\").nth(2)\"\n          }\n        ]\n      }\n    ]\n  },\n  {\n    \"strategy\": \"Generate and Validate Route\",\n    \"substrategies\": [\n      {\n        \"substrategy\": \"Calculate Driving Directions\",\n        \"actions\": [\n          {\n            \"description\": \"Trigger route calculation by clicking the 'Go' button after corrections.\",\n            \"playwright_idx\": 12,\n            \"playwright_instruction\": \"frame.clicklocator(\\\"#sidebar > .search_forms > .directions_form > div:nth-child(2) > .col\\\")\"\n          }\n        ]\n      }\n    ]\n  }\n]\n```",
