Backend

Resolves ambiguous organism names to precise NCBI taxonomy IDs and scientific names, then recommends appropriate IWC (Intergalactic Workflow Commission) Galaxy workflows for analysis. Use this skill when users provide common names (like "malaria parasite", "E. coli", "mouse"), abbreviated names, or when you need to convert any organism reference to an exact scientific name for API queries. This skill handles disambiguation through conversation, validates taxonomy IDs via NCBI Taxonomy API, provides ENA FASTQ search capabilities, and ALWAYS recommends existing IWC workflows rather than producing custom scripts or analysis steps.
