Analyze Current Skill

Purpose

Read and understand the current baseline implementation. Extract all relevant information about the existing approach without modifying anything, and record the analysis as a structured JSON entry.

When to Use

Phase 1 — after experiment setup is complete and files are copied to the experiment folder.

Input

experiments/{research_name}/

Actions

1. Read

   {experiment_path}/current.ipynb

   and extract:
   • Model/algorithm used
   • Preprocessing steps (encoding, scaling, feature selection, etc.)
   • Training approach (train/test split ratio, cross-validation, etc.)
   • Hyperparameters
   • Metrics used and their values
   • Target variable and feature set

2. Extract dependencies:

   • Scan all import statements in the notebook.
   • Write

     {experiment_path}/current_requirements.txt

     with one package per line (

     package==version

     if determinable, otherwise just

     package

     ).

3. Read

   {experiment_path}/current_data/

   (or, for code-based data, the download spec):
   • Identify data format (CSV, parquet, etc.)
   • Note number of rows, columns
   • Note data types and any special handling

4. Append a Phase 1 entry to

   {experiment_path}/log.json

   under

   phases

   :

   {
     "name": "Phase 1: Analyze Current",
     "completed_at": "2026-04-17T10:15:00Z",
     "model": "XGBoost",
     "preprocessing": [
       "Drop rows with NaN",
       "LabelEncoder on target",
       "LabelEncoder on categorical features",
       "StandardScaler on numerical features"
     ],
     "training": {
       "split": 0.2,
       "seed": 42,
       "stratified": true
     },
     "hyperparameters": {
       "n_estimators": 200,
       "max_depth": 6,
       "learning_rate": 0.1
     },
     "metrics": {
       "accuracy": 0.8726,
       "f1":       0.7277,
       "roc_auc":  0.9274
     },
     "target": "income",
     "features_count": 14,
     "data": {
       "source": "ucimlrepo fetch_ucirepo(id=2)",
       "format": "pandas.DataFrame",
       "rows": 45222,
       "cols": 14
     },
     "notes": "Data downloaded programmatically; both notebooks must use the same source."
   }
   

   Do not overwrite earlier entries; append to the

   phases

   array.

Output

• {experiment_path}/log.json

  — updated with complete Phase 1 analysis entry

• {experiment_path}/current_requirements.txt

  — written
• No other files created or modified
