Tooling: Validation & Generation

[PipFoweraker]

Goal

Build tools that reduce friction for card authors and enable automated validation.

Core Tools

1. Schema Validator

Input: JSON/JSON-LD model card
Output: Validation report

Features:

• JSON Schema validation against spec
• Link checking (do evidence URLs resolve?)
• Disclosure completeness score calculation
• Tier consistency checking (claimed tier vs actual disclosure)
• MUST/SHOULD/CAN compliance summary

imc validate card.json --tier=2 --check-links

2. Card Generator (Interactive)

Input: Prompts + author responses
Output: Valid JSON-LD card

Features:

• CLI wizard walking through questions
• Web form interface
• Import from existing formats (HF model card YAML, CycloneDX)
• Suggest evidence links from common sources

imc init --tier=1 --base-model=meta-llama/Llama-3-8B

3. Card Renderer

Input: JSON-LD card
Output: Human-readable formats

Features:

• Markdown (GitHub/HF compatible)
• HTML (standalone page)
• PDF (for compliance documentation)
• Disclosure heatmap visualization

imc render card.json --format=markdown --output=MODEL_CARD.md

4. Diff Tool

Input: Two card versions
Output: Semantic diff

Features:

• Highlight changed disclosures
• Track disclosure completeness over time
• Changelog generation

imc diff card-v1.json card-v2.json

Implementation Considerations

Language/Framework

• Python likely best for ML ecosystem integration
• Consider: standalone CLI vs library vs both
• Package name: interrogatory-model-cards or imc

Dependencies

• jsonschema for validation
• requests for link checking
• jinja2 for rendering templates
• click or typer for CLI

Integration Points

• HuggingFace Hub API (fetch existing cards, push new ones)
• GitHub Actions (CI validation)
• Pre-commit hooks

Deliverables

1. tools/imc/ - Python package
2. tools/imc/cli.py - command-line interface
3. GitHub Action for PR validation
4. PyPI package (eventually)

• Evidence Linking Protocol (link checker implementation)
• Frontend: Interactive Demo Website (may share rendering logic)
