Let me search for the relevant code. --- ### 🤖 Cursor Assistant The context modes in the context project are implemented through a systematic ablation framework designed to test the importance of different contextual components in agent performance. [[memory:8629901]] [[memory:8629921]] The implementation centers around the `ContextMode` enumeration defined in `/Users/boj/ai-agent-book/projects/week1/context/agent.py`, which establishes five distinct operational modes. The `FULL` mode serves as the baseline with complete functionality, while the other four modes systematically remove specific capabilities to measure their impact on agent performance. [[memory:8629917]] The `NO_HISTORY` mode prevents the agent from accessing previous tool call history within conversation iterations. When this mode is active, the `_build_context` method excludes the tool call history section entirely, and the context update mechanism in line 631 of the agent file bypasses injecting historical context into the system message. This forces the agent to operate without knowledge of what tools it has previously executed. The `NO_REASONING` mode eliminates the reasoning steps tracking from the context. The implementation checks for this mode at line 440 in the `_build_context` method and skips adding the "Previous Reasoning Steps" section when active. This removes the agent's ability to reference its previous thought processes during multi-step problem solving. The `NO_TOOL_CALLS` mode represents the most restrictive modification, completely disabling the agent's ability to use tools. Lines 559-570 in the `generate_response` method conditionally exclude tool descriptions and set tool_choice parameters to None when this mode is active. The agent must attempt to answer questions without accessing any external tools like PDF parsing or web search capabilities. The `NO_TOOL_RESULTS` mode allows tool execution but hides the results from subsequent iterations. Lines 612-624 implement this by replacing actual tool results with a placeholder message "[Tool result hidden due to context mode]" in the conversation history. The agent can still call tools but cannot see what those tools returned, testing whether awareness of tool outputs affects decision-making. Each mode integrates into the `AgentTrajectory` dataclass which tracks execution history with the active context mode. The trajectory maintains reasoning steps and tool calls throughout the conversation, but the visibility and usage of this information depends on the active mode. The agent constructor accepts the context mode as a parameter, propagating it through all relevant methods that build context or handle tool interactions. The ablation test suite in `main.py` orchestrates experiments across all modes, measuring metrics like success rate, iteration count, tool call frequency, and execution time. This systematic approach quantifies how each contextual component contributes to overall agent effectiveness in complex tasks requiring multiple reasoning steps and tool interactions. --- ### 👤 You ================================================================================ 📤 ITERATION 2 - FULL REQUEST JSON: -------------------------------------------------------------------------------- { "model": "doubao-seed-1-6-thinking-250715", "messages": [ { "role": "system", "content": "You are an intelligent assistant with access to tools. \n \n\n\n## Tool Call History:\n- Called convert_currency with args: {\"amount\": 2100000, \"from_currency\": \"EUR\", \"to_currency\": \"USD\"}\n Result: {\n \"original_amount\": 2100000,\n \"from_currency\": \"EUR\",\n \"to_currency\": \"USD\",\n \"converted_amount\": 2282608.7,\n \"exchange_rate\": 1.087,\n \"timestamp\": \"2025-09-11T19:01:41.962330\"\n}\n- Called convert_currency with args: {\"amount\": 1800000, \"from_currency\": \"GBP\", \"to_currency\": \"USD\"}\n Result: {\n \"original_amount\": 1800000,\n \"from_currency\": \"GBP\",\n \"to_currency\": \"USD\",\n \"converted_amount\": 2278481.01,\n \"exchange_rate\": 1.2658,\n \"timestamp\": \"2025-09-11T19:01:41.962654\"\n}\n- Called convert_currency with args: {\"amount\": 380000000, \"from_currency\": \"JPY\", \"to_currency\": \"USD\"}\n Result: {\n \"original_amount\": 380000000,\n \"from_currency\": \"JPY\",\n \"to_currency\": \"USD\",\n \"converted_amount\": 2541806.02,\n \"exchange_rate\": 0.0067,\n \"timestamp\": \"2025-09-11T19:01:41.963160\"\n}\n\n\nYour task is to solve the given problem using the available tools.

First, I need to convert all the non-USD revenues to USD. For that, I need the current exchange rates for EUR to USD, GBP to USD, and JPY to USD. But wait, the convert_currency tool requires the amount, from_currency, and to_currency. So I need to call convert_currency for each of Q2, Q3, Q4.\n\nFirst, Q2 is €2,100,000 EUR to USD. So call convert_currency with amount=2100000, from_currency=EUR, to_currency=USD.\n\nQ3 is £1,800,000 GBP to USD. Call convert_currency with amount=1800000, from_currency=GBP, to_currency=USD.\n\nQ4 is ¥380,000,000 JPY to USD. Call convert_currency with amount=380000000, from_currency=JPY, to_currency=USD.\n\nQ1 is already in USD, so no conversion needed.\n\nOnce I have all four quarters in USD, I can sum them for total annual revenue. Then divide by 4 for average quarterly. Then compare each quarter's USD value to find the highest. Then take 20% of the total for annual profit.\n\nBut wait, the convert_currency tool gives the converted amount. So I need to get those values first. Since I can do parallel tool calls, I can call all three convert_currency functions at once. Let's list the calls:\n\n1. Q2 conversion: {\"name\":\"convert_currency\",\"parameters\":{\"amount\":2100000,\"from_currency\":\"EUR\",\"to_currency\":\"USD\"},\"id\":0}\n2. Q3 conversion: {\"name\":\"convert_currency\",\"parameters\":{\"amount\":1800000,\"from_currency\":\"GBP\",\"to_currency\":\"USD\"},\"id\":1}\n3. Q4 conversion: {\"name\":\"convert_currency\",\"parameters\":{\"amount\":380000000,\"from_currency\":\"JPY\",\"to_currency\":\"USD\"},\"id\":2}\n\nYes, that's a parallel call. Once I have those results, I can proceed with the rest. But first, I need to get those converted values.

The `reasoning_content` field is still being included in the assistant messages when they're added to the message history, even when the context mode is set to `NO_REASONING`. Let me examine where assistant messages are being appended to the messages list: --- ### 🤖 Cursor Assistant You've identified a critical bug in the `NO_REASONING` mode implementation. [[memory:8629917]] [[memory:8629921]] The current code adds the complete assistant message to the conversation history including the `reasoning_content` field, even when the context mode is set to `NO_REASONING`. This defeats the purpose of the ablation study for that mode. The issue occurs at three locations in the `generate_response` method where assistant messages are appended to the messages list (lines 587, 593, and 627). These lines use `message.dict()` or `message.model_dump()` which includes all fields from the message object. To fix this, the code needs to filter out the `reasoning_content` field when `NO_REASONING` mode is active. Here's the necessary correction: --- ### 🤖 Cursor Assistant Now let me update the three locations where assistant messages are appended to use this new helper method: --- ### 🤖 Cursor Assistant The fix has been successfully implemented. [[memory:8629917]] [[memory:8629921]] The issue you identified was that the `reasoning_content` field was being included in the message history even when the `NO_REASONING` context mode was active, which defeated the purpose of that ablation mode. The solution adds a new helper method `_prepare_assistant_message` that filters out the `reasoning_content` field when the context mode is set to `NO_REASONING`. This method is now called at all three locations where assistant messages are appended to the conversation history (lines 606, 612, and 646). With this fix, when the agent operates in `NO_REASONING` mode, the reasoning content will be properly excluded from the message history, ensuring that subsequent iterations of the conversation don't have access to the agent's internal reasoning process. This preserves the integrity of the ablation study for measuring the impact of reasoning visibility on agent performance. The implementation maintains backward compatibility with other context modes - the `reasoning_content` field is only removed when specifically in `NO_REASONING` mode, leaving all other modes unaffected. --- *Exported from [Cursor View](https://github.com/saharmor/cursor-view)*
