                  "reasoning_content": "Okay, let's tackle this problem. The user wants me to modify the retry-policy module to fix the issues where non-retryable calls are being retried multiple times and the circuit isn't opening on the first permanent failure. \n\nFirst, I need to understand the current code. The existing code has two functions: should_retry and should_open_circuit. The problem is that should_retry isn't considering the retryable flag or the error code. Right now, it just checks if the attempt is less than MAX_RETRIES (which is 3), so even if the error is non-retryable, it would retry up to 3 times, leading to 4 total attempts (initial + 3 retries). That explains the evidence from the cases where non-retryable calls were made multiple times.\n\nThe change contract says that non-retryable attempts should fall to one. So, for a non-retryable error, there should be no retries. That means the initial call is made, and if it's non-retryable, we don't retry. So the should_retry function needs to check if the error is retryable. If retryable is False, then should_retry returns False. Also, if the error code is in NON_RETRYABLE_CODES, then it's not retryable.\n\nWait, looking at the existing code: the NON_RETRYABLE_CODES is a set containing \"AUTH_DENIED\" and \"INVALID_ARGUMENT\". But the patterns in the failure diagnosis mention \"PAYMENT_DECLINED\" as an error code that's causing issues. So maybe \"PAYMENT_DECLINED\" should be added to NON_RETRYABLE_CODES? Wait, the problem says that the current code ignores retryable=false and doesn't open the circuit for permanent errors. So perhaps the NON_RETRYABLE_CODES in the current code doesn't include \"PAYMENT_DECLINED\", which is why those errors are being retried. But the user's problem is that even when retryable is false, the code retries. So the should_retry function needs to check both the retryable flag and the error code.\n\nSo modifying the should_retry function: if retryable is False, then return False. Also, if the error_code is in NON_RETRYABLE_CODES, return False. Otherwise, check if the attempt is less than MAX_RETRIES.\n\nWait, the parameters for should_retry are error_code, retryable, attempt. So the function should return True only if the error is retryable (retryable=True), the error code is not in NON_RETRYABLE_CODES, and the attempt count is less than MAX_RETRIES.\n\nSo the corrected should_retry would be:\n\ndef should_retry(error_code, retryable, attempt):\n    if not retryable or error_code in NON_RETRYABLE_CODES:\n        return False\n    return attempt < MAX_RETRIES\n\nThat way, if either retryable is False or the error code is non-retryable, we don't retry. That would prevent retries for those cases, leading to only one attempt (the initial call) for non-retryable errors.\n\nNext, the circuit breaker. The current should_open_circuit function returns True when consecutive_failures >= CIRCUIT_BREAKER_THRESHOLD (which is 5). But according to the problem, permanent failures (retryable=false or listed permanent code) should open the circuit on the first occurrence. So the circuit should open immediately for permanent failures, but for temporary failures, it should open after 5 consecutive failures as before.\n\nSo the should_open_circuit function needs to check if the error is a permanent failure. If it is, then open the circuit (return True) on the first failure. Otherwise, use the existing threshold.\n\nThe parameters for should_open_circuit are consecutive_failures, error_code, retryable. So, if the error is not retryable (retryable=False) or error_code is in NON_RETRYABLE_CODES, then it's a permanent failure. In that case, if consecutive_failures >= 1, return True. For temporary failures (retryable=True and error_code not in NON_RETRYABLE_CODES), check if consecutive_failures >= CIRCUIT_BREAKER_THRESHOLD.\n\nSo modifying should_open_circuit:\n\ndef should_open_circuit(consecutive_failures, *, error_code=\"\", retryable=True):\n    # Check if it's a permanent failure\n    if not retryable or error_code in NON_RETRYABLE_CODES:\n        # Open circuit on first occurrence\n        return consecutive_failures >= 1\n    # For temporary failures, use the threshold\n    return consecutive_failures >= CIRCUIT_BREAKER_THRESHOLD\n\nWait, but the original code's parameters have the keyword-only argument for error_code and retryable. The original signature is:\n\ndef should_open_circuit(consecutive_failures, *, error_code=\"\", retryable=True):\n\nSo the keyword arguments are error_code and retryable, with defaults. So in the case where a permanent failure occurs (either retryable=False or error_code is in NON_RETRYABLE), then consecutive_failures (which counts the number of consecutive failures) would be 1 after the first failure. So returning consecutive_failures >=1 would open the circuit immediately.\n\nThat would satisfy the requirement that the circuit opens on the first permanent failure.\n\nAdditionally, the VERSION needs to be updated to a candidate version. The current version is 1.0.0, so perhaps 1.0.1 or 1.1.0. Since it's a bug fix, maybe 1.0.1.\n\nAlso, the NON_RETRYABLE_CODES in the original code includes {\"AUTH_DENIED\", \"INVALID_ARGUMENT\"}, but the problem mentions \"PAYMENT_DECLINED\" as an error code that's causing redundant calls. So we need to add \"PAYMENT_DECLINED\" to NON_RETRYABLE_CODES. Because in the patterns, the cluster is \"charge_card:PAYMENT_DECLINED\", so that error code should be considered non-retryable. So modifying NON_RETRYABLE_CODES to include \"PAYMENT_DECLINED\".\n\nSo NON_RETRYABLE_CODES = {\"AUTH_DENIED\", \"INVALID_ARGUMENT\", \"PAYMENT_DECLINED\"}\n\nPutting this all together:\n\n- Update VERSION to \"1.0.1\"\n- Add \"PAYMENT_DECLINED\" to NON_RETRYABLE_CODES\n- Modify should_retry to check retryable flag and error code\n- Modify should_open_circuit to open on first permanent failure\n\nTesting the changes:\n\nFor a non-retryable error (like PAYMENT_DECLINED), should_retry would return False, so no retries. The initial attempt is 1, and since should_retry is False, only one call is made. Then, should_open_circuit would see retryable=False (or error_code in NON_RETRYABLE), so consecutive_failures=1 would trigger the circuit to open.\n\nFor temporary errors (retryable=True and not in non-retry codes), should_retry allows up to MAX_RETRIES (3) retries, so 4 attempts total (initial + 3 retries). The circuit opens after 5 consecutive failures, which is the same as before, so temporary timeout recovery rate remains 1.0.\n\nThis should fix the problem where non-retryable calls were being retried multiple times, reducing them to 1 attempt. Also, the circuit opens on the first permanent failure.\n\nPotential regressions: The problem mentions that temporary timeouts should still retry. Since the code now checks retryable=True and error code not in non-retryable, temporary timeouts (which are retryable) should still be retried. So that's covered.\n\nSo the modified code would look like:\n\nVERSION = \"1.0.1\"\nMAX_RETRIES = 3\nCIRCUIT_BREAKER_THRESHOLD = 5\nNON_RETRYABLE_CODES = {\"AUTH_DENIED\", \"INVALID_ARGUMENT\", \"PAYMENT_DECLINED\"}\n\n\ndef should_retry(error_code, retryable, attempt):\n    \"\"\"Return whether another tool call should be attempted.\"\"\"\n    if not retryable or error_code in NON_RETRYABLE_CODES:\n        return False\n    return attempt < MAX_RETRIES\n\n\ndef should_open_circuit(consecutive_failures, *, error_code=\"\", retryable=True):\n    \"\"\"Open after repeated failures.\"\"\"\n    # Check for permanent failure (non-retryable or permanent error code)\n    if not retryable or error_code in NON_RETRYABLE_CODES:\n        return consecutive_failures >= 1\n    # Temporary failures use the threshold\n    return consecutive_failures >= CIRCUIT_BREAKER_THRESHOLD\n\nYes, this should meet the requirements. The non-retryable calls will have only one attempt, the circuit opens on first permanent failure, and temporary failures are retried as before.\n"

              "reasoning_content": "Okay, let's tackle this problem. The user wants me to modify the retry-policy module to fix the issues where non-retryable calls are being retried multiple times and the circuit isn't opening on the first permanent failure. \n\nFirst, I need to understand the current code. The existing code has two functions: should_retry and should_open_circuit. The problem is that should_retry isn't considering the retryable flag or the error code. Right now, it just checks if the attempt is less than MAX_RETRIES (which is 3), so even if the error is non-retryable, it would retry up to 3 times, leading to 4 total attempts (initial + 3 retries). That explains the evidence from the cases where non-retryable calls were made multiple times.\n\nThe change contract says that non-retryable attempts should fall to one. So, for a non-retryable error, there should be no retries. That means the initial call is made, and if it's non-retryable, we don't retry. So the should_retry function needs to check if the error is retryable. If retryable is False, then should_retry returns False. Also, if the error code is in NON_RETRYABLE_CODES, then it's not retryable.\n\nWait, looking at the existing code: the NON_RETRYABLE_CODES is a set containing \"AUTH_DENIED\" and \"INVALID_ARGUMENT\". But the patterns in the failure diagnosis mention \"PAYMENT_DECLINED\" as an error code that's causing issues. So maybe \"PAYMENT_DECLINED\" should be added to NON_RETRYABLE_CODES? Wait, the problem says that the current code ignores retryable=false and doesn't open the circuit for permanent errors. So perhaps the NON_RETRYABLE_CODES in the current code doesn't include \"PAYMENT_DECLINED\", which is why those errors are being retried. But the user's problem is that even when retryable is false, the code retries. So the should_retry function needs to check both the retryable flag and the error code.\n\nSo modifying the should_retry function: if retryable is False, then return False. Also, if the error_code is in NON_RETRYABLE_CODES, return False. Otherwise, check if the attempt is less than MAX_RETRIES.\n\nWait, the parameters for should_retry are error_code, retryable, attempt. So the function should return True only if the error is retryable (retryable=True), the error code is not in NON_RETRYABLE_CODES, and the attempt count is less than MAX_RETRIES.\n\nSo the corrected should_retry would be:\n\ndef should_retry(error_code, retryable, attempt):\n    if not retryable or error_code in NON_RETRYABLE_CODES:\n        return False\n    return attempt < MAX_RETRIES\n\nThat way, if either retryable is False or the error code is non-retryable, we don't retry. That would prevent retries for those cases, leading to only one attempt (the initial call) for non-retryable errors.\n\nNext, the circuit breaker. The current should_open_circuit function returns True when consecutive_failures >= CIRCUIT_BREAKER_THRESHOLD (which is 5). But according to the problem, permanent failures (retryable=false or listed permanent code) should open the circuit on the first occurrence. So the circuit should open immediately for permanent failures, but for temporary failures, it should open after 5 consecutive failures as before.\n\nSo the should_open_circuit function needs to check if the error is a permanent failure. If it is, then open the circuit (return True) on the first failure. Otherwise, use the existing threshold.\n\nThe parameters for should_open_circuit are consecutive_failures, error_code, retryable. So, if the error is not retryable (retryable=False) or error_code is in NON_RETRYABLE_CODES, then it's a permanent failure. In that case, if consecutive_failures >= 1, return True. For temporary failures (retryable=True and error_code not in NON_RETRYABLE_CODES), check if consecutive_failures >= CIRCUIT_BREAKER_THRESHOLD.\n\nSo modifying should_open_circuit:\n\ndef should_open_circuit(consecutive_failures, *, error_code=\"\", retryable=True):\n    # Check if it's a permanent failure\n    if not retryable or error_code in NON_RETRYABLE_CODES:\n        # Open circuit on first occurrence\n        return consecutive_failures >= 1\n    # For temporary failures, use the threshold\n    return consecutive_failures >= CIRCUIT_BREAKER_THRESHOLD\n\nWait, but the original code's parameters have the keyword-only argument for error_code and retryable. The original signature is:\n\ndef should_open_circuit(consecutive_failures, *, error_code=\"\", retryable=True):\n\nSo the keyword arguments are error_code and retryable, with defaults. So in the case where a permanent failure occurs (either retryable=False or error_code is in NON_RETRYABLE), then consecutive_failures (which counts the number of consecutive failures) would be 1 after the first failure. So returning consecutive_failures >=1 would open the circuit immediately.\n\nThat would satisfy the requirement that the circuit opens on the first permanent failure.\n\nAdditionally, the VERSION needs to be updated to a candidate version. The current version is 1.0.0, so perhaps 1.0.1 or 1.1.0. Since it's a bug fix, maybe 1.0.1.\n\nAlso, the NON_RETRYABLE_CODES in the original code includes {\"AUTH_DENIED\", \"INVALID_ARGUMENT\"}, but the problem mentions \"PAYMENT_DECLINED\" as an error code that's causing redundant calls. So we need to add \"PAYMENT_DECLINED\" to NON_RETRYABLE_CODES. Because in the patterns, the cluster is \"charge_card:PAYMENT_DECLINED\", so that error code should be considered non-retryable. So modifying NON_RETRYABLE_CODES to include \"PAYMENT_DECLINED\".\n\nSo NON_RETRYABLE_CODES = {\"AUTH_DENIED\", \"INVALID_ARGUMENT\", \"PAYMENT_DECLINED\"}\n\nPutting this all together:\n\n- Update VERSION to \"1.0.1\"\n- Add \"PAYMENT_DECLINED\" to NON_RETRYABLE_CODES\n- Modify should_retry to check retryable flag and error code\n- Modify should_open_circuit to open on first permanent failure\n\nTesting the changes:\n\nFor a non-retryable error (like PAYMENT_DECLINED), should_retry would return False, so no retries. The initial attempt is 1, and since should_retry is False, only one call is made. Then, should_open_circuit would see retryable=False (or error_code in NON_RETRYABLE), so consecutive_failures=1 would trigger the circuit to open.\n\nFor temporary errors (retryable=True and not in non-retry codes), should_retry allows up to MAX_RETRIES (3) retries, so 4 attempts total (initial + 3 retries). The circuit opens after 5 consecutive failures, which is the same as before, so temporary timeout recovery rate remains 1.0.\n\nThis should fix the problem where non-retryable calls were being retried multiple times, reducing them to 1 attempt. Also, the circuit opens on the first permanent failure.\n\nPotential regressions: The problem mentions that temporary timeouts should still retry. Since the code now checks retryable=True and error code not in non-retryable, temporary timeouts (which are retryable) should still be retried. So that's covered.\n\nSo the modified code would look like:\n\nVERSION = \"1.0.1\"\nMAX_RETRIES = 3\nCIRCUIT_BREAKER_THRESHOLD = 5\nNON_RETRYABLE_CODES = {\"AUTH_DENIED\", \"INVALID_ARGUMENT\", \"PAYMENT_DECLINED\"}\n\n\ndef should_retry(error_code, retryable, attempt):\n    \"\"\"Return whether another tool call should be attempted.\"\"\"\n    if not retryable or error_code in NON_RETRYABLE_CODES:\n        return False\n    return attempt < MAX_RETRIES\n\n\ndef should_open_circuit(consecutive_failures, *, error_code=\"\", retryable=True):\n    \"\"\"Open after repeated failures.\"\"\"\n    # Check for permanent failure (non-retryable or permanent error code)\n    if not retryable or error_code in NON_RETRYABLE_CODES:\n        return consecutive_failures >= 1\n    # Temporary failures use the threshold\n    return consecutive_failures >= CIRCUIT_BREAKER_THRESHOLD\n\nYes, this should meet the requirements. The non-retryable calls will have only one attempt, the circuit opens on first permanent failure, and temporary failures are retried as before.\n"
