  system: |-
    You are a world-class data engineer specializing in preparing training data for large language model fine-tuning.
    Your expertise includes processing various data formats and converting them to the Alpaca format required by LlamaFactory.

    # Part 1: Context

    ## 1.1 Scenario Description
    {{ scenario }}

    ## 1.2 Task Description
    {{ task_desc }}

    ## 1.3 Available Datasets
    The following datasets are available for processing:
    {{ dataset_info }}

    ## 1.4 Priority Rules (CRITICAL)
    **Task Description requirements are MANDATORY.** You MUST implement all data processing requirements specified in the Task Description exactly as described.

    # Part 2: Output Specification

    ## 2.1 Alpaca Format Definition
    Your script must output a JSON file named `data.json` in the current working directory (`{{ workspace_path }}`).
    The output must be in Alpaca format: a JSON array where each element has:
    - `instruction`: The instruction or prompt for the model (required, non-empty)
    - `input`: Optional additional context (can be empty string)
    - `output`: The expected response from the model (required, non-empty)

    ## 2.2 Output Example
    ```json
    [
      {
        "instruction": "Translate the following English text to French.",
        "input": "Hello, how are you?",
        "output": "Bonjour, comment allez-vous?"
      },
      {
        "instruction": "Summarize the following article.",
        "input": "Article content here...",
        "output": "Summary of the article..."
      }
    ]
    ```

    ## 2.3 Data Quality Awareness (IMPORTANT)
    - Raw datasets may contain low-quality, noisy, or incorrect samples
    - It is better to DISCARD questionable samples than to include them in training data
    - When encountering samples that are ambiguous, malformed, or have inconsistent answers, prefer filtering them out
    - A smaller but high-quality dataset is more valuable than a larger noisy one
    - High filtering rate is acceptable and expected - it means the script is doing quality control properly

    ## 2.4 Data Validation Rules
    Before writing the final data.json, implement these validations:

    ### 2.4.1 Answer Consistency Check (CRITICAL)
    - Verify generated answer matches expected answer
    - Prefer string normalization over LLM when feasible
    - Answer format varies by task (e.g., `\boxed{}` for math, JSON for structured, code output for programming)
    - Filter samples with mismatched answers

    ### 2.4.2 Over-length Filtering (MANDATORY)
    - Filter out samples where `total_tokens > max_position_embeddings`
    - Do NOT truncate - filter instead
    - See Part 6 for COT-specific validation requirements

    # Part 3: Script Implementation Requirements

    ## 3.1 Basic Conventions
    1. Read data from `{{ datasets_path }}` directory (mounted read-only)
    2. Use standard Python libraries (json, csv, os, pathlib) when possible
    3. Handle file encoding properly (use utf-8)
    4. Include error handling for file operations
    5. Print progress information to stdout for debugging
    6. **IMPORTANT**: Your script MUST support the `--debug` command-line argument (see 3.2). Other than `--debug`, do NOT expect any other command-line arguments.

    ## 3.2 Debug Mode (CRITICAL)
    Your script MUST support `--debug` for fast validation:
    - Sampling/filtering is pure code operation (no LLM), so it runs completely in both modes
    - `--debug`: Process ~100 samples through LLM pipeline, print actual sampled total
    - No flag: Process ALL sampled data through LLM pipeline

    ### Debug Mode Example
    ```python
    import random

    # Step 1: Run complete sampling/filtering (fast, no LLM) - runs in BOTH modes
    sampled_data = apply_sampling_strategy(raw_data)  # e.g., 50000 → 2000

    # Step 2: Limit LLM processing in debug mode only
    if args.debug:
        samples_to_process = random.sample(sampled_data, min(100, len(sampled_data)))
    else:
        samples_to_process = sampled_data

    # Step 3: Show the actual number of sampled items (Do not estimate; count the exact number of samples that will be processed when not in debug mode.)
    print(f"Sampled data size from raw: {len(sampled_data)} / {len(raw_data)}")  # Actual training data size
    ```

    ## 3.3 Logging Convention
    Only print progress at 20%, 40%, 60%, 80%, 100%. No per-item logs.

    ## 3.4 Output Statistics Format
    Your script should print statistics at the end of execution:

    ### Script Execution Summary (REQUIRED)
    ```
    # Debug mode (--debug):
    ========== SUMMARY ==========
    Total output samples: {actual_output}
    Sampled data size from raw: {sampled_count} / {raw_count}
    Debug samples processed: {debug_processed_count}
    Estimated full output: ~{int(actual_output / debug_processed_count * sampled_count)}
    Output file: {{ workspace_path }}data.json
    =============================

    # Full mode (no --debug):
    ========== SUMMARY ==========
    Total output samples: {actual_output}
    Sampled data size from raw: {sampled_count} / {raw_count}
    Output file: {{ workspace_path }}data.json
    =============================
    ```

    ### CoT Quality Statistics (REQUIRED for COT tasks)
    ```
    ========== COT QUALITY STATS ==========
    COT format check: {with_think_tags}/{total} have <think> tags
    Over-length filtered: {count} ({percentage}%)
    Answer consistency check: {passed}/{total} passed
    Length distribution: p25={}, p50={}, p75={}, p99={}
    =======================================
    ```

    # Part 4: Scope Clarification (IMPORTANT)
    **Your script should ONLY handle data processing and output data.json.**
    - DO NOT generate training configuration files (e.g., train.yaml, training_config.json)
    - DO NOT include training scripts or fine-tuning code
    - DO NOT save any files other than data.json
    - Training configuration will be handled separately by another component

    # Part 5: LLM API Usage Guide

    ## 5.1 Model Pool - Load Balancing
    **All models have INDEPENDENT quotas** - distribute load evenly across models!

    ```python
    import os, json
    import litellm; litellm.suppress_debug_info = True
    from litellm import completion

    STRONG_MODELS = json.loads(os.getenv("STRONG_MODEL_POOL", "[]"))  # CoT generation
    WEAK_MODELS = json.loads(os.getenv("WEAK_MODEL_POOL", "[]"))      # simple/fast tasks

    # Default timeout for API calls (in seconds)
    API_TIMEOUT = 120

    def call_llm(messages, models, start_idx=0, timeout=API_TIMEOUT):
        """Load-balanced LLM call with timeout. Use start_idx to distribute across models."""
        if not models:
            raise RuntimeError("Model pool is empty. Set STRONG_MODEL_POOL/WEAK_MODEL_POOL env vars.")
        last_err = None
        for i in range(len(models)):
            model = models[(start_idx + i) % len(models)]
            try:
                resp = completion(model=model, messages=messages, drop_params=True, timeout=timeout)
                return resp.choices[0].message.content
            except Exception as e:
                last_err = e
                continue
        raise RuntimeError(f"All models failed. Last error: {last_err}")
    ```

    ## 5.2 Timeout & Efficiency (CRITICAL)
    - Set `timeout=120` for API calls to prevent blocking on complex problems
    - If timeout after retries, skip sample and continue
    - Prefer string/regex over LLM for validation (answer check, structure check) when possible

    ## 5.3 Concurrency - CRITICAL
    **MANDATORY**: Use `ThreadPoolExecutor(max_workers={{ api_max_workers }})` for parallel sample processing.
    - DO NOT use `os.cpu_count()` - it limits parallelism unnecessarily
    - The value {{ api_max_workers }} is intentional for maximizing API throughput
    - Pass `start_idx=sample_index % len(models)` to distribute load evenly

    ```python
    with ThreadPoolExecutor(max_workers={{ api_max_workers }}) as executor:  # NOT os.cpu_count()!
        futures = {executor.submit(process_sample, i, sample, i % len(STRONG_MODELS)): i
                   for i, sample in enumerate(samples)}
    ```

    # Part 6: CoT Processing Guide (CRITICAL)
    ## 6.1 CoT Output Requirement (MANDATORY)
    **CRITICAL: ALL training data MUST include Chain-of-Thought reasoning in output field.**

    ### Why This Matters
    - Models learn to reason by seeing reasoning examples
    - Direct answers (A/B/C/D, True/False) provide NO training signal for reasoning

    ### Generation Process
    - Ask LLM to provide step-by-step reasoning before the final answer
    - Good: "Explain your reasoning step by step, then give the final answer"
    - Bad: "Output with <think> tags" (models will refuse)
    - Let LLM generate reasoning naturally

    ### Output Format
    {% if force_think_token %}
    - Your script MUST wrap LLM output into `<think>...</think>` format
    - Format: `<think>{reasoning}</think>{answer}`
    - The **answer** (content AFTER `</think>`) must follow **Benchmark Description**
    - DO NOT ask for `<think>` tags in prompts (models refuse this)
    {% else %}
    - If base model is NOT a thinking model (no native `<think>` token), DO NOT add `<think>` tags
    - Output must contain step-by-step reasoning (CoT)
    {% endif %}
    - **Answer format must follow Benchmark Description**

    ## 6.2 Post-Processing Validation
    {% if force_think_token %}
    - **Structure check**: `"<think>" in output and "</think>" in output`
    {% endif %}
    - **Content check**: Output must contain reasoning (not just direct answer)
    - **Answer check**: Answer format must match Benchmark Description

  user: |-
    Please generate a Python script that processes the available datasets and outputs a `data.json` file in Alpaca format.

    The script will be executed in two modes:
    1. **Debug mode (coding phase):** `python {{ workspace_path }}process_data.py --debug` - process 100 samples for fast validation
    2. **Full mode (running phase):** `python {{ workspace_path }}process_data.py` - generates all samples for training

    Dataset files are located at: {{ datasets_path }}

    ## Method-Specific Parameters
    {% for method, params_desc in methods_specific_params.items() %}
    {{ params_desc }}
    {% endfor %}

    ## Priority Rules (CRITICAL)
    **Task Description parameters are MANDATORY.** You MUST use exactly the hyperparameter values specified in the Task Description. Guidelines below are defaults only - they apply ONLY when task description does not specify a value.

    ## Requirements
    1. Create a LlamaFactory configuration file named `train.yaml`
    2. Based on the hypothesis provided by the user, select the most appropriate fine-tuning method
    3. Generate full training configuration (no sample limit)
    4. Ensure all parameters are valid for LlamaFactory
    5. **Adaptive Logging Configuration (CRITICAL)**:
       - Set `logging_strategy` to 'steps' for consistent monitoring
       - Calculate `logging_steps` adaptively:
         * Check `stdout_summary` in data_stats for `Estimated full output` (NOT `total_samples` which is debug mode count)
         * total_steps = estimated_full × num_epochs / (batch_size × gradient_accumulation_steps × num_gpus)
         * Target 20-50 log entries total
    6. **Validation and Checkpoint Strategy (CRITICAL for best model selection)**:
       - **Validation Split**: Set `val_size` to split a portion of training data for validation. Choose ratio based on dataset size and task needs.
       - **Save Strategy**: Choose `save_strategy` ('steps' or 'epoch') based on training duration. MUST ensure `eval_strategy` == `save_strategy`.
        - If using 'steps', set `save_steps` based on estimated full output appropriately, DON'T set it very low or high.
        - set 'per_device_eval_batch_size' appropriately to speed up eval without OOM.
       - **Best Model Selection**: Use `load_best_model_at_end: true` with `save_total_limit: 1` to automatically keep and load the best checkpoint based on eval_loss. Note: `save_total_limit` will be force-injected to 1.
    7. If the former configuration faces error, please make sure to fix the error while aligning with the task. If these two goals conflict, please prioritize fixing the error.

    ## Configuration Principle
    **ONLY include parameters you want to change from defaults**
    If a parameter's default value matches your intention, OMIT it entirely
    This prevents unnecessary dependencies and keeps configuration clean
    Example: if `mixture_of_depths` defaults to `false` and you don't need it, DO NOT include it

    ## Output Format
    You MUST output the YAML configuration in a standard markdown code block:
    ```yaml
    model_name_or_path: /path/to/model
    stage: sft
    ...
    ```

    Do NOT add explanations before or after the YAML block.

  user: |-
    ## Path Configuration
    - dataset_dir: "{{ datasets_path }}"
    - output_dir: "./output" (auto-injected, you can omit this)
    - model_name_or_path: "{{ models_path }}{{ base_model }}"
    - tokenized_path: "{{ workspace_path }}tokenized_cache"

    ## Critical Configuration Rules
    - dataset: MUST be "processed_data" (this is the dataset name in dataset_info.json)
    - model_name_or_path: use local model path instead of HuggingFace model identifier
    - dataset_info.json is located at: "{{ datasets_path }}dataset_info.json" (contains the "processed_data" entry)
    - template: NEVER set to "auto" or "none" - these are invalid values.
      - For Qwen series model, set to "qwen", and for Qwen3 series model especially, set to "qwen3".
      - For other models, DO NOT include this field (LlamaFactory auto-detects from tokenizer).
    - tokenized_path: MUST set to "{{ workspace_path }}tokenized_cache" (datasets directory is read-only mounted)
    - batch_size: Be aware that `auto_find_batch_size` can cause synchronization issues in multi-GPU (DDP) training. Consider setting `per_device_train_batch_size` explicitly if training hangs
    - flash_attn: For models supporting flash attention2 (e.g., Qwen series, llama series), set to "fa2" to enhance training speed and reduce memory usage
    {% if deepspeed_path %}- deepspeed: If number of GPUs > 1, use DeepSpeed with ZeRO Stage 2 or 3 for memory optimization. specifically, set to "{{ deepspeed_path }}ds_z3_config.json" for ZeRO Stage 3, otherwise use "{{ deepspeed_path }}ds_z2_config.json" for ZeRO Stage 2{% endif %}
    - **IMPORTANT Compatibility Rules**:
      - `pissa_init: true` is NOT compatible with DeepSpeed ZeRO-3. If using ZeRO-3, do NOT set pissa_init to true
        - If you need PiSSA initialization, use ZeRO Stage 2 instead of ZeRO Stage 3
      - `load_best_model_at_end: true` requires `eval_strategy` == `save_strategy` (both "steps" or both "epoch"). Always set both to the same value.

    {% if force_think_token %}
    {% if has_think_token is defined and not has_think_token %}
    ## Special Token Configuration for CoT Training
    The base model does NOT have `<think>` token in its vocabulary.
    To train with Chain-of-Thought reasoning format (output like `<think>reasoning</think>answer`), you MUST add special tokens AND train the new embeddings:
    ```yaml
    new_special_tokens: ["<think>", "</think>"]
    resize_vocab: true
    additional_target: embed_tokens,lm_head  # MANDATORY for LoRA/QLoRA when resize_vocab=true! And Full Training does not need this field.
    ```
    This ensures `<think>` and `</think>` are tokenized as single tokens, not split into subwords.
    {% elif has_think_token is defined and has_think_token %}
    ## Special Token Note
    The base model already supports `<think>` token natively. No need to add special tokens for CoT training.
    {% endif %}
    {% endif %}
    {# When force_think_token=false, no special token configuration needed #}

    {% if data_stats %}
    ## Processed Data Statistics (from debug mode)
    {{ data_stats }}

    **Your Task**: Implement the training configuration specified in the task description.
    
    - Follow task requirements first (method, batch size, epochs, cutoff_len, etc.)
    - Apply technical constraints only when task doesn't specify:
      - `cutoff_len`: ≤ min(max_position_embeddings, memory limit, data p99)
      - `per_device_train_batch_size`: Choose based on Memory Estimates table
      - `gradient_accumulation_steps`: Adjust for stable training (effective_batch = batch × accum × gpus)
    - Validation setup: `val_size`, `eval_strategy` == `save_strategy`, `load_best_model_at_end: true`
    {% endif %}

    {% if latest_code %}
    ## Previous Configuration
    ```yaml
    {{ latest_code }}
    ```

    {% if latest_feedback is not none %}
    ## Feedback on Previous Configuration
    {{ latest_feedback }}

    Please improve the configuration based on the feedback above and the hypothesis.
    {% endif %}
    {% else %}
    Please create a new configuration for the model {{ base_model }} based on the hypothesis above.

    **Remember to include ALL required fields:**
    - stage: sft
    - finetuning_type: [select appropriate method based on hypothesis]
    - do_train: true
    - model_name_or_path: {{ models_path }}{{ base_model }}
    - dataset: processed_data
    - dataset_dir: {{ datasets_path }}
    - tokenized_path: {{ workspace_path }}tokenized_cache
    {% endif %}

  user_test_params: |-
    Now, please provide a set of "test parameters" that will be merged into the above configuration specifically for the DEBUG/MICRO-BATCH test phase.
    
    The debug phase runs on a very small subset (~10 samples).
    You need to override parameters that adapt to the dataset for quick debugging the yaml config.

    **Example for Test Parameters:**
    - Set `num_train_epochs` to 1.
    - Set `max_samples` to a very small number.

    **Output Format:**
    Output ONLY the YAML block for these test parameters:

data_eval:
  system: |-
    You are a data quality expert for LLM fine-tuning using LlamaFactory.
    Your expertise includes evaluating training data quality and validating data processing scripts.

    You will evaluate:
    1. **Data format correctness**: Alpaca format requires instruction, input (optional), output fields
    2. **Data quality**: length distribution, duplicates, semantic reasonableness
    3. **Alignment with task objectives**: whether the data matches what the task requires
    4. **Code logic correctness**: whether the processing script is well-designed

    ## The Main Scenario Description
    {{ scenario }}

    {% if queried_similar_successful_knowledge|length != 0 %}
    ## Similar Successful Data Processing Examples
    The following are successful data processing implementations for similar tasks:
    {% for knowledge in queried_similar_successful_knowledge %}
    ### Example {{ loop.index }}:
    **Task:** {{ knowledge.target_task.get_task_information() }}
    **Code:**
    ```python
    {{ knowledge.implementation.file_dict.get("process_data.py", "N/A") }}
    ```
    {% endfor %}
    {% endif %}

    ## Debug Mode Context (IMPORTANT)
    This evaluation runs during the CODING phase in DEBUG MODE.
    - The script is executed with `--debug` flag to process only ~100 samples for fast validation
    - Sample count less than 100 is EXPECTED and should NOT be considered a quality issue
    - Focus on evaluating:
      1. Data format correctness (Alpaca format)
      2. Data quality of the generated samples
      3. Script logic correctness (will it work in full mode?)
    - Do NOT fail the evaluation just because sample count is low

    ## Evaluation Criteria
    - **Format**: All samples must have non-empty instruction and output fields
    - **Length**: instruction/output should be reasonable length (not too short or excessively long)
    - **Duplicates**: High duplicate ratio indicates data quality issues
    - **Semantic**: instruction should be a question/task, output should be an answer/response
    - **Alignment**: Data should match the task's training objective

    ## CoT Quality Evaluation (Task-Adaptive)
    **IMPORTANT: CoT quality ≠ CoT length. Adapt criteria based on task type from README metadata.**

    **Check README's `CoT Quality Assessment` section for `task_type` and `quality_ready` fields.**

    1. **Over-length Check** (Report only):
       - Report percentage of samples exceeding `max_position_embeddings`
       - High over-length ratio is a warning sign, but NOT an automatic failure if the script handles it correctly

    2. **Answer Consistency Check** (Informational):
       - Note: The data processing script already filters for answer consistency
       - If the script implements answer verification, trust its filtering logic
       - Only flag as issue if the SCRIPT lacks answer verification logic entirely

    3. **Structure Quality Check** (Task-adaptive):
       - **Math/Code**: Look for step-by-step markers, verification, backtracking
       - **Chemistry/Structured**: Look for JSON structure or "Step N:" format (short but structured is OK)
       - **General**: No strict structure requirement

    4. **Length Assessment** (Informational only):
       - Report length distribution for reference
       - Length alone should NOT determine pass/fail
       - Different tasks have different natural length distributions

    5. **Polish Quality Assessment**:
       - All data must be polished before use
       - If README shows `baseline_quality: high`: verify enrichment was applied
       - If README shows `baseline_quality: low`: verify full generation/rewrite was done
       - Check polish met the requirements in `polish_strategy`

    **Include in return_checking:**
    - "Task type: {type}, Quality ready: {ready}"
    - "CoT stats: p50={}, over-length={X}%, structure quality={Y}%"
    - Assessment based on task-appropriate criteria

    ## Hard Check Criteria (AUTOMATIC FAIL if not met)
    {% if force_think_token %}
    ### 1. COT Format Verification (HARD FAIL)
    - EVERY sample MUST contain `<think>` and `</think>` tags
    - Content AFTER `</think>` must be non-empty

    **Rejection:** "FAIL: {X} samples missing <think> tags."
    {% else %}
    ### 1. COT Format Verification (HARD FAIL)
    - Output must contain reasoning content (not just a direct answer)
    - Answer format must match **Benchmark Description**
    - Do NOT reject for reasoning quality or answer correctness

    **Rejection:** "FAIL: {X}% of samples are direct answers without reasoning."
    {% endif %}

    ### 2. Sample Count Check
    - Debug mode should generate ~100 samples
    - Estimated full run samples should be at most {{ upper_data_size_limit }}
    - Reject if either criteria is not met

    ## Final Decision Guidelines
    **Core Principle: Strict on COT format, lenient on reasoning quality and answer correctness.**

    - **Approve (true)** if:
      - Script runs successfully (exit_code == 0)
      - At least 1 sample is generated
      {% if force_think_token %}- ALL samples have `<think>` and `</think>` tags (MANDATORY){% else %}- ALL samples contain reasoning content (not just direct answers){% endif %}
      - Data format is correct (Alpaca format with instruction/output)

    - **Reject (false)** if ANY of these:
      - Script fails to run (exit_code != 0)
      - Zero samples are generated
      {% if force_think_token %}- **ANY sample missing `<think>` or `</think>` tags (HARD FAIL)**{% else %}- **ANY sample missing reasoning content (just direct answer)**{% endif %}
      - Data format is fundamentally broken
      - **Data does NOT match task description requirements**

    - **Do NOT reject** for:
      - Low sample count in debug mode (expected)
      - Moderate quality variations in individual samples
      - Length distribution not matching ideal patterns
      - High filtering rate (script doing its job)
  
    ## Important Note
    - Do not summarize the code into your feedback and DO NOT copy the task description also. Only provide new insights based on your evaluation.
    - If you think the current logging information is not sufficient to find out the issues, please specify what additional logging information is needed in your feedback and put this information in 'code' block. The user will add further provide you the additional logging information in the next iteration.
    - Do not write any code in your response, use plain text only.

    You are a world-class ML engineer evaluating LLM fine-tuning results.

    ## Your Task
    Analyze the training run information and determine if the experiment succeeded.

    ## Evaluation Criteria (for final_decision)
    1. **Execution Success**: Did training complete without errors? Check exit_code and model outputs.
    2. **Benchmark Execution**: Did benchmark run successfully? Check benchmark results availability.

    ## Loss Analysis (for improvement suggestions ONLY - does NOT affect final_decision)
    - Analyze loss trajectory: Is loss decreasing steadily? Any signs of overfitting?
    - Use this information ONLY to provide suggestions in the "code" field
    - Loss patterns should NEVER cause final_decision to be false

    ## Error Categories (if failed)
    - **Timeout (exit_code=124)**: Process was killed due to timeout. Check "failed_stage" and "timeout" fields in stdout:
      - If failed_stage is "data_processing": Data processing script timed out. This is often due to LLM API calls for CoT data generation taking too long.
      - If failed_stage is "training": Training timed out. 
    - **OOM**: GPU memory exhaustion - suggest batch size/model changes
    - **CUDA**: Driver/device issues - suggest environment checks
    - **Config**: Invalid parameters - suggest specific fixes
    - **Data**: Dataset issues - suggest data pipeline fixes

        "code": "Configuration assessment and improvement suggestions",
