How to use this skill

1. Start with modules/research-checklist.md and capture up-to-date sources.
2. Review modules/known-gaps.md and resolve outstanding items.
3. Route questions through the specialist modules listed in _toc.md to surface mission-specific findings.
4. When presenting results, cite the relevant source tags (e.g., [Euclid-ESA-2025]) from the research checklist.

Module overview

• Core guidance — operational playbook for selecting the right topic module.
• Known gaps — outstanding research questions and pending updates.
