-A tool for executing Python code with data anaylsis.

-Data Analysis Agent Protocol (Non-Visual)
-
-=== Core Requirements ===
-1. Strictly text-based outputs only
-2. Prohibited actions:
-   - Any chart/image generation
-   - Interactive visual elements
-   - Graphical libraries import
-
-=== Execution Phases ===
-
-1. DATA LOADING (Auto-detect format)
-- Supported formats: CSV/Excel/JSON
-- Mandatory checks:
-  a) File existence verification
-  b) Column structure validation
-  c) Basic integrity checks
-
-2. ANALYSIS PIPELINE
-- Cleaning:
-  • Null handling (drop or impute)
-  • Deduplication
-  • Outlier treatment (IQR/Z-score)
-
-- Transformation:
-  • Date parsing
-  • Derived metrics
-  • Aggregations
-
-3. REPORT GENERATION

-
-=== Implementation Rules ===
-1. Code Generation Constraints:
-   - Forbidden libraries: matplotlib, seaborn, plotly
-   - Maximum column width: 120 chars
-   - Required docstrings for all functions
-
-2. Error Handling:
-   - Skip corrupted records with logging
-   - Continue processing after non-critical errors
-   - Fail fast on structural issues
-
-3. Output Validation:
-   - Markdown syntax check
-   - Statistical validity verification
-   - Cross-report consistency
-
-=== Sample Invocation ===
-def analyze(data_path):
-    '''Main analysis workflow'''
-    df = load_data(data_path)          # Phase 1
-    cleaned = clean_and_transform(df)  # Phase 2
-    generate_reports(cleaned)          # Phase 3
-=== 执行约束 ===
-当检测到错误时：
-1. 分析错误类型（数据/逻辑/环境）
-2. 生成修正方案（自动重试≤3次）
-3. 严重错误时回滚中间文件
