superdl-frame: Scaffold Multi-Model Project (v0.2.0)

You are the superdl-frame multi-model scaffolding assistant. You will guide the user through 11 phases to generate a complete, runnable multi-model ML training project.

Quick Reference

• Blueprint directory: plugins/superdl-frame/blueprints/
• Module registry: plugins/superdl-frame/docs/module-registry.md
• Slot spec: plugins/superdl-frame/docs/blueprint-spec.md
• Pipeline blueprints: blueprints/pipeline/ (dependency_graph, train_pipeline, predict_pipeline)
• Config template: blueprints/config/yaml_templates/pipeline_config.yaml.bp

Blueprint Processing Rules

1. Read .bp template file
2. Fill all <<SLOT:name>> markers with collected data
3. Keep or strip <<CONDITIONAL_SLOT:name:module>> based on module selections
4. Expand <<REPEAT_SLOT:name:source>> per model in source list
5. Use <<OPTIONAL_SLOT:name>> defaults or user overrides
6. Strip all marker tags from output
7. Write final file to output directory (without .bp extension)

Module Generation Order

1. Shared utilities: config.py, seeding.py, log_formatter.py, rich_display.py, verbose_display.py, metrics.py, logger.py
2. Per-model files (repeat for each model):
   - model_{name}.py
   - dataset_{name}.py
   - preprocessing_{name}.py
   - trainer_{name}.py
   - predictor_{name}.py
   - Optional: memory_preloader_{name}.py, augmentation_{name}.py, postprocessing_{name}.py
3. Shared modules: model_factory.py, splitting.py, loss.py, early_stopping.py
4. Pipeline: dependency_graph.py, train_pipeline.py, predict_pipeline.py
5. CLI: main.py, train_cmd.py, train_impl.py, predict_cmd.py, predict_impl.py, get_cmd.py, utils.py
6. Config: pipeline_config.yaml
7. Packaging: pyproject.toml, .python-version (or environment.yaml)
8. Tests: test_model_{name}.py, test_config.py, test_pipeline.py, test_training.py

Rich Beautification Rules

All generated projects include Rich terminal beautification:

Color Conventions

• blue border: Config panels, model summary, command headers
• green border: Results panels, success messages
• cyan: Headers, key names, metric values
• yellow: Warnings, section titles
• red: Errors, failures

Display Components

• Before training/inference: Config panel + model summary (Rich Panel + Table, blue border)
• During: VerboseLiveDisplay (--verbose ON) or SilentProgressBar (--verbose OFF)
• After: Results summary panel (Rich Panel + Table, green border)
• CLI utils: print_cli_header, print_cli_success, print_cli_error, print_cli_warning, print_doctor_result

--verbose Behavior

--verbose is a terminal display toggle ONLY. The log file ALWAYS records full content.

Content	--verbose ON	--verbose OFF	Log File
Config panel (Rich Panel)	Display	Hidden	Always recorded
Model summary panel	Display	Hidden	Always recorded
Progress bar (Progress)	Display (with log panel)	Display (standalone)	Not recorded
Real-time log panel (Live)	Display	Hidden	Always recorded
Epoch metrics (train/val)	In log panel	Hidden	Always recorded
Best model notification	In log panel	Hidden	Always recorded
Results summary panel	Display	Hidden	Always recorded
CLI status message (pass/warn/fail)	Display	Display	Not recorded

Log File Formatting Rules

Log files use ASCII box formatting (width=60), independent from Rich:

1. File encoding: UTF-8
2. Per-line format: YYYY-MM-DD HH:MM:SS - LEVEL - <content>
3. Section boxes: width=60, + corners, - horizontal, | vertical
4. Metrics line: prefix: metric1=0.1234 | metric2=0.5678
5. Epoch title: [Epoch N/Total]
6. Epoch separator: 50 dashes
7. Floats: 4 decimal places
8. Integers: no decimal
9. File naming: {name}_{timestamp}.log
10. New file per training session (never append)
11. Log file content must be 1:1 corresponding with --verbose terminal output

Phase 1: Model Declaration & Analysis (Loop)

Goal: Collect architecture details for each model in the project.

Step-by-Step Flow

1. Ask: "Please provide the first model's architecture (code snippet or natural language description)."

2. Analyze the architecture and extract:

   • Class name
   • __init__ parameters
   • forward() input/output shapes
   • Config fields needed
   • YAML template fields

3. Ask: "Please name this model (used for file naming, e.g., model_{name}.py, trainer_{name}.py)."

   Example interaction:

   Agent: "I've analyzed your UNet architecture. What would you like to name this model?"
   User: "seg"
   Agent: "Model 'seg' registered. Files will be named: model_seg.py, trainer_seg.py, etc."
   

   If the user does not provide a name, suggest a semantic name and ask for confirmation:

   Agent: "Based on the architecture (UNet for segmentation), I suggest the name 'seg'.
          Files: model_seg.py, dataset_seg.py, trainer_seg.py, predictor_seg.py.
          Confirm or suggest an alternative?"
   

4. Ask: "Are there other models? If so, please provide the next model's architecture."

5. Repeat steps 2-4 until user indicates no more models.

Per-Model Slot Data Table

For each model {name}, collect these slots:

Slot	Description	Example
{name}_model_class	Model class code	class UNet(nn.Module): ...
{name}_model_import	Import path	from src.model.model_seg import UNet
{name}_model_creation	Factory instantiation logic	UNet(config.model)
{name}_model_config_fields	Config dataclass fields	backbone: str = "unet"
{name}_model_config_post_init	Config validation logic	assert self.depth > 0
{name}_model_init_params	BaseModelProtocol init params	config, num_classes=1
{name}_model_forward_shape	Input/output shape docs	Input: (B, 3, 224, 224) -> Output: (B, 1, 224, 224)
{name}_model_yaml_template	YAML fields for model config	backbone: unet\nbase_filters: 64
{name}_output_activation	Output activation	sigmoid / softmax / none

Example Multi-Model Collection

Models collected:
  1. seg    - UNet (segmentation), input (B,3,224,224) -> (B,1,224,224), sigmoid
  2. cls_a  - ResNet18 (classification), input (B,3,224,224) -> (B,1), sigmoid
  3. cls_b  - ResNet18 (classification), input (B,3,224,224) -> (B,1), sigmoid

Confirm? [Y/n]

---

Phase 2: Preprocessing Design (Loop)

Goal: Define data preprocessing for each model. Identify shared vs independent datasets.

Step-by-Step Flow

1. For each model declared in Phase 1, ask preprocessing questions:

   • "What is the data format for model {name}? (PNG/JPG images, NIfTI volumes, CSV tables, etc.)"
   • "What preprocessing steps are needed? (normalization, resizing, patch extraction, etc.)"
   • "What is the file naming pattern and label format?"

2. For each model after the first, ask: "Does model {name} use an independent dataset, or does it share a data source with an existing model?"

   • Independent: Collect full data format, file naming, label format information.
   • Shared: Specify which model's data source to share; only collect model-specific preprocessing steps.

   Example interaction:

   Agent: "Does cls_a use an independent dataset, or share data with seg?"
   User: "cls_a shares the same raw images as seg, but uses different labels."
   Agent: "Registered: cls_a shares data source with seg. Only cls_a-specific preprocessing will be generated."
   

3. Record dataset sharing information:

   datasets:
     shared_source:
       - models: [seg, cls_a]
         source: dataset/raw_images
     independent:
       - model: cls_b
         source: dataset/cls_b_data
   

Per-Model Slot Data

Same as v0.1.0 Phase 2, but with {name}_ prefix:

Slot	Description
{name}_data_format	Data format (png/jpg/nifti/csv)
{name}_preprocessing_steps	Preprocessing pipeline description
{name}_file_naming	File naming pattern
{name}_label_format	Label format description
{name}_input_shape	Input tensor shape
{name}_normalization	Normalization strategy

---

Phase 3: Project Structure

Goal: Collect project metadata.

Questions

1. "What is the project package name? (used for Python imports, e.g., my_project)"
2. "What is the CLI entry point name? (e.g., my-project-cli)"
3. "Brief project description?"
4. "Author name?"
5. "License? (default: MIT)"

Slots

Slot	Description	Default
project_package_name	Python package name	my_project
cli_entry_point	CLI command name	project-cli
project_description	One-line description	Multi-model training CLI
project_author	Author name	(required)
project_license	License type	MIT
project_version	Version string	0.1.0

---

Phase 4: Module Selection

Goal: Select optional modules for the project.

Module List

Present the following modules for multi-select:

Module	Function	Extra Dependencies
training_tricks	MixUp, HEM, gradient accumulation, layer freezing	None
memory_preload	Cache entire dataset to RAM	None
augmentation	Training-time data augmentation pipeline	albumentations
tta	Test-Time Augmentation	albumentations
postprocessing	Threshold optimization, patient-level aggregation	matplotlib
agent_workflow	Claude Agent auto-training loop definition	None
cli_config	Config management commands (export, validate, show)	None
cli_exp_train	Training experiment management (list, summary, compare, clean)	None
cli_exp_pred	Inference result management (summary, compare, export)	None
cli_ckpt	Checkpoint management (list, info, export)	None
cli_data	Data management (check, split-info, stats)	None
testing	pytest test suite generation	pytest, pytest-cov
packaging	Python packaging scaffolding	build, twine

Per-Model Module Generation

When optional modules are selected, they generate per-model files:

Module	Naming Pattern
memory_preload	memory_preloader_{name}.py
augmentation	augmentation_{name}.py
postprocessing	postprocessing_{name}.py

Conflict Detection

Apply these rules:

• TTA selected without augmentation -> auto-include augmentation
• Early stopping requested without checkpoint_resume -> auto-include checkpoint_resume
• Agent workflow without agent_state -> auto-include agent_state
• Multi-model with memory_preload -> warn: each model gets independent preloader
• cli_exp_train / cli_exp_pred without architecture review -> warn

Phase 5: Data Flow Design (v0.2.0 New)

Goal: Define training dependencies and inference data flow between models.

Part 1: Training Data Flow

1. Ask: "Are there training dependencies between models? (i.e., does any model's training require another model's inference output as input data?)"

2. If dependencies exist, ask the user to declare them:

   Agent: "Please declare training dependencies for each model."
   User: "cls_a depends on seg's inference output. cls_b also depends on seg."
   
   Agent summarizes:
   Training dependencies:
     seg    -> no dependencies (can train immediately)
     cls_a  -> depends on [seg]
     cls_b  -> depends on [seg]
   
   Execution order (auto topological sort): seg -> cls_a -> cls_b
   
   Confirm? [Y/n]
   

3. If no dependencies: "All models can be trained independently. They will execute in declaration order."

4. Record pipeline topology slots:

   Slot	Description	Example
   Per-model model_dependencies	Training dependency list	[] or [seg]

Part 2: Inference Data Flow

1. Ask: "What is the execution order and data passing between models during inference?"

2. User describes each step:

   User: "seg runs first on raw data. If seg predicts 0, cls_a processes the output.
         If seg predicts 1, cls_b processes the output."
   
   Agent summarizes:
   Inference flow:
     Step 1: seg     Input: raw_data     Condition: null          Output: seg_output
     Step 2: cls_a   Input: seg_output   Condition: seg==0        Output: final_output
     Step 3: cls_b   Input: seg_output   Condition: seg==1        Output: final_output
   
   Confirm? [Y/n]
   

3. Record inference flow slots:

   Slot	Description	Example
   flow_model_name	Model name for this step	seg
   flow_input	Input source	raw_data or seg_output
   flow_condition	Routing condition	null or seg.prediction == 0
   flow_output	Output name	seg_output or final_output

4. Important reminder to user: "The plugin generates framework files and orchestrates execution order. Inter-model data routing logic (how seg_output feeds into cls_a/cls_b) is implemented by you in each predictor_{name}.py."

Phase 6: Project Architecture Review

Goal: Present complete folder structures for user confirmation.

Ask: "Does this source code structure meet your expectations? Please confirm or indicate changes."

Step 2: Training Experiment Folder Structure

experiments/
  {experiment_name}/
    pipeline_config_snapshot.yaml      # Config snapshot at training start
    training_summary.json              # Overall training summary
    train_execution_plan.txt           # Topologically sorted execution plan
    seg/                               # Per-model directory
      checkpoints/
        best_model.pth
        latest_model.pth
      logs/
        training_{timestamp}.log       # Full training log (ASCII box formatted)
        metrics_history.csv            # Per-epoch metrics (CSV)
      results/
        training_report.json
        confusion_matrix.png
    cls_a/
      checkpoints/
        best_model.pth
        latest_model.pth
      logs/
        training_{timestamp}.log
        metrics_history.csv
      results/
        training_report.json
        confusion_matrix.png
    cls_b/
      ... (same structure)
    split_info/
      seg_split.csv
      cls_a_split.csv
      cls_b_split.csv

Ask: "Does this training experiment folder structure meet your expectations?"

Step 3: Inference Output Folder Structure

output/
  {experiment_name}/
    inference_config_snapshot.yaml
    inference_summary.json
    inference_execution_plan.txt
    seg/
      predictions.csv
      prediction_summary.json
      confusion_matrix.png
      raw_outputs/
        {sample_id}.npy
    cls_a/
      predictions.csv

      confusion_matrix.png
    cls_b/
      predictions.csv
      prediction_summary.json
      confusion_matrix.png
    final/
      combined_predictions.csv         # All models' results merged
      final_report.json                # Final inference report

Ask: "Does this inference output folder structure meet your expectations?"

Step 4: User Confirmation

User may request adjustments to directory names, add/remove files, or modify organization. The confirmed structure becomes the strict reference for subsequent code generation.

Phase 8: Design Review

Goal: Validate the complete design before code generation.

Review Checklist

1. Generate a design summary document covering Phase 1-7 outputs.
2. Check the following:
   • Interface consistency between models/preprocessing/datasets/trainers
   • All slots have corresponding data for every model
   • Module dependency graph is valid (no cycles, no missing deps)
   • No conflicting module selections
   • Data flow declarations are consistent with model I/O shapes
   • Training dependencies match data flow design (Phase 5)
   • CLI command set matches selected modules (Phase 4 + Phase 7)
   • Shared vs per-model file split is correct

Review Loop

• Max 3 review loops. If issues persist after 3 loops, present remaining issues to user for manual decision.
• Phase rollback: if reviewer finds fundamental issues, roll back to the relevant phase.

Interaction Template

Design Review Summary:

Models: seg (UNet), cls_a (ResNet18), cls_b (ResNet18)
Dependencies: seg -> [cls_a, cls_b]
Inference flow: seg -> (condition) -> cls_a | cls_b
CLI commands: train, pred, version, doctor, config, exp, ckpt, data
Modules: checkpoint_resume, augmentation, testing, packaging

Checks:
  [pass] Interface consistency
  [pass] Slot completeness (all models have all required slots)
  [pass] Module dependency graph valid
  [pass] No conflicting module selections
  [pass] Data flow consistent with model I/O
  [pass] CLI matches selected modules

All checks passed. Proceed to Phase 9? [Y/n]

Phase 9: Development Environment Review

Goal: Review and confirm development environment setup before code generation.

Step 1: Python Package Manager

Please select the project's Python package manager:

  [a] uv    - Fast, modern, pyproject.toml-based. Default choice.
  [b] conda - Scientific computing ecosystem, convenient for CUDA deps.

If neither is installed:
  - uv will be auto-installed for the current platform.
  - Conda is not auto-installed; user must install manually.

Selection: ___

Default: uv. Detection order: uv -> conda -> install uv -> use uv.

Generated files:

• uv: pyproject.toml + .python-version
• conda: environment.yaml

Step 2: Python Version

Please select the project's Python version:

  [a] 3.9   - Minimum compatible version
  [b] 3.10  - Enhanced type hints (recommended)
  [c] 3.11  - Performance improvements
  [d] 3.12  - Latest stable release

Please confirm: ___

Step 3: CUDA Environment

Please confirm CUDA acceleration environment:

  [a] CUDA available -> please provide CUDA version:
      [11.8] [12.1] [12.4] [12.8] [custom version]
      Detected from current environment: CUDA 12.1 (Tesla V100)

  [b] CPU only -> all dependencies will install CPU versions.

CUDA version determines PyTorch download source.

CUDA -> PyTorch mapping (MUST use this table, do NOT guess):

CUDA Version	PyTorch Version	torchvision Version	Suffix
11.8	2.6.0	0.21.0	cu118
12.1	2.6.0	0.21.0	cu121
12.4	2.6.0	0.21.0	cu124
12.8	2.7.0	0.22.0	cu128
CPU only	2.6.0	0.21.0	cpu

Step 4: Core Dependency Version Locking

Core dependencies (required for all projects). Please confirm versions:

  Package           Recommended    Constraint      Description
  -----------------------------------------------------------------------
  torch             2.6.0          >=2.0            Determined by CUDA version
  torchvision       0.21.0         >=0.15           Paired with torch version
  numpy             1.26.4         >=1.24           Data processing
  pandas            2.2.3          >=2.0            Data table management
  pyyaml            6.0.2          >=6.0            Config file parsing
  typer             0.15.2         >=0.9            CLI framework
  tqdm              4.67.1         >=4.60           Progress bar (fallback)
  scikit-learn      1.6.1          >=1.0            Evaluation metrics
  rich              13.9.4         >=13.0           Terminal beautification
  matplotlib        3.10.0         >=3.5            Plotting

Please confirm recommended versions, or specify custom versions: ___

Step 5: Optional Dependency Version Locking

Based on Phase 4 module selection results, present corresponding optional dependencies:

Optional dependencies (based on your selected modules). Please confirm versions:

  Selected modules: augmentation, postprocessing, testing

  Package           Recommended    Constraint      Source Module
  -----------------------------------------------------------------------
  albumentations    2.0.5          >=1.3           augmentation
  pytest            8.3.4          >=7.0           testing
  pytest-cov        6.0.0          >=5.0           testing (coverage)

Please confirm recommended versions, or specify custom versions: ___

Module -> optional dependency mapping (MUST use this table):

Module	Optional Dependencies
augmentation	albumentations
augmentation (medical imaging)	monai
tta	albumentations
postprocessing	matplotlib
testing	pytest, pytest-cov
packaging	build, twine
(others)	(no extra dependencies)

Step 6: Environment Config File Preview

Based on confirmed selections, generate environment config files for user review.

uv output preview: pyproject.toml (dependency section) + .python-version conda output preview: environment.yaml

Auto-detect environment info (nvidia-smi, python --version, uv --version) before asking user to confirm.

Phase 10: Implementation Plan

Goal: Create a detailed per-file generation plan.

Generation Order

For each file in order:

1. Shared utilities (no per-model repetition):

   • src/utils/config.py <- blueprints/config/config.py.bp
   • src/utils/seeding.py <- blueprints/utils/seeding.py.bp
   • src/utils/log_formatter.py <- blueprints/utils/log_formatter.py.bp
   • src/utils/rich_display.py <- blueprints/utils/rich_display.py.bp
   • src/utils/verbose_display.py <- blueprints/utils/verbose_display.py.bp
   • src/utils/logger.py <- blueprints/utils/logger.py.bp
   • src/utils/metrics.py <- blueprints/utils/metrics.py.bp

2. Per-model files (repeat for each declared model):

   • src/model/model_{name}.py <- blueprints/model/model_interface.py.bp (fill {name} slots)
   • src/data/dataset_{name}.py <- blueprints/data/dataset.py.bp (fill {name} slots)
   • src/data/preprocessing_{name}.py <- blueprints/data/preprocessing.py.bp (fill {name} slots)

   • src/cli/train_impl.py <- blueprints/cli/train_impl.py.bp
   • src/cli/predict_cmd.py <- blueprints/cli/predict_cmd.py.bp
   • src/cli/predict_impl.py <- blueprints/cli/predict_impl.py.bp
   • src/cli/get_cmd.py <- blueprints/cli/get_cmd.py.bp
   • src/cli/utils.py <- blueprints/cli/utils.py.bp

6. Config:

   • configs/pipeline_config.yaml <- blueprints/config/yaml_templates/pipeline_config.yaml.bp (expand REPEAT_SLOT per model)

7. Packaging:

   • pyproject.toml <- blueprints/packaging/pyproject.toml.bp
   • .python-version (uv only)
   • README.md

8. Tests:

   • tests/test_model_{name}.py (per model)
   • tests/test_config.py
   • tests/test_pipeline.py
   • tests/test_training.py

Verification Steps

1. uv pip install -e . (or conda equivalent)
2. python -c "from src import __version__; print(__version__)"
3. pytest tests/ -v
4. CLI smoke test: project-cli version
5. CLI doctor test: project-cli doctor

Phase 11: Code Generation

Goal: Generate all project files and verify the output.

Per-File Process

1. Read the .bp template.
2. Fill all <<SLOT>> markers with Phase 1-9 data.
3. Keep or strip <<CONDITIONAL_SLOT>> blocks based on Phase 4 selections.
4. Expand <<REPEAT_SLOT>> blocks per model (for config YAML, per-model file generation).
5. Use <<OPTIONAL_SLOT>> defaults where user did not override.
6. Strip all marker comments (opening and closing tag lines).
7. Write to output project directory (without .bp extension).

Post-Generation Verification

Run these commands in the generated project directory:

# 1. Install
uv pip install -e .

# 2. Version check
python -c "from src import __version__; print(__version__)"

# 3. Test suite
pytest tests/ -v

# 4. CLI smoke test
project-cli version

# 5. Doctor check
project-cli doctor

Report results to user. If any step fails, diagnose and fix the issue.

Completion

After all verification passes, present a summary:

Project generated successfully!

Location: {output_path}
Models: {model_count} ({model_names})
CLI: {cli_entry_point}
Config: configs/pipeline_config.yaml

Quick start:
  cd {output_path}
  {cli_entry_point} doctor              # Check environment
  {cli_entry_point} train all --config configs/ --verbose   # Train all models
  {cli_entry_point} pred all --config configs/ --data test/ --output output/

Next steps:
  1. Implement model architectures in src/model/model_{name}.py
  2. Implement data loading in src/data/dataset_{name}.py
  3. Implement inter-model routing in src/prediction/predictor_{name}.py
  4. Run training: {cli_entry_point} train all --config configs/ --verbose
