Default Variables Reference

Osmedeus workflows use template variables for dynamic content substitution. Variables are enclosed in double curly braces: {{variable}}.

Template Syntax

Standard Variables

Standard variables use {{variable}} syntax and are evaluated at step execution time.

command: "nuclei -l {{Output}}/urls.txt -t {{Data}}/templates/"

Secondary Variables (Foreach)

Foreach loops use [[variable]] syntax to avoid conflicts with standard templates:

- name: scan-each
  type: foreach
  input: "{{Output}}/subdomains.txt"
  variable: sub
  step:
    type: bash
    command: "httpx -u [[sub]] >> {{Output}}/httpx.txt"
