Dataset Contribution Hub: Patterns, Sheets, and Company Coverage

[im-anishraj]

This thread is for coordinating dataset improvements.

Dooma currently has strong company-question coverage, but the highest-impact dataset work is improving pattern tags and completing roadmap mappings.

Priority Dataset Work

• Add pattern tags for common categories like Two Pointers, Sliding Window, Binary Search, Graph, and Dynamic Programming.
• Complete NeetCode 150 mappings.
• Complete Striver SDE mappings.
• Add validation for unknown pattern and sheet references.
• Detect duplicate URLs or duplicate question records.

Contribution Rules

• Keep YAML readable.
• Prefer precise tags over broad or noisy tags.
• Leave ambiguous questions unchanged unless you explain the reasoning.
• Rebuild dooma/data/index.json after YAML changes.
• Include validation output in the PR.

Validation Commands

python scripts/build_index.py
python scripts/build_index.py --check
python -m pytest tests/test_loader.py
