Nextflow Workflow Writer

Create complete Nextflow workflows by composing validated modules from the Nextflow Registry.

Modules are published under namespaces (e.g. nf-core/fastqc), and these skills compose modules from any of them.

Requires Nextflow 26.04 or later (for the nextflow module commands used during validation). Including workflow modules requires Nextflow 26.10 or later.

Registry modules come in two kinds (shown as Kind: by nextflow module view):

• Process modules — one tool, e.g. nf-core/star/align
• Workflow modules — a reusable subworkflow chaining several modules, e.g. nf-core/fastq_align_star (STAR alignment + samtools sort/index/stats)

NEVER write a wrapper workflow just to run/test a single module.
