What problem does it solve? Nature Portfolio writing, polishing, and review skills often need the same ethics rules, journal formatting facts, and manuscript-consistency guidance; this package centralizes those shared definitions so sibling skills load one authoritative copy instead of duplicating content. ## Core Features & Use Cases - Shared core references: Supplies ethics and AI-disclosure rules, paper-type taxonomy, terminology ledgers, consistency-sweep methodology, main-text discipline, and corpus-derived guidance for Nature-style abstracts, introductions, results, and discussions. - Journal format facts: Provides stage-aware submission requirements for flagship Nature, Nature Communications, and Nature Machine Intelligence, including word limits, display-item budgets, and data/code availability rules. - Mechanical consistency checker: Includes scripts/check_consistency.py, which flags terminology variants, equal numbers reported at different precisions, and equivalent lengths written in different units. - Use Case: When the nature-polishing skill audits a revised manuscript, it loads core/consistency-sweep.md from this package and runs the bundled checker to surface terminology drift before editing. ## Quick Start Ask your installed Nature skill to load the specific shared file it needs, such as the Nature Machine Intelligence formatting rules, from the nature-shared package.
