Save a reusable multi-step workflow that chains this server's tools. Each step is {tool, args, as?}. Args may reference {{input.x}} (values supplied at run time) or {{steps..}} (output of an earlier step; steps without 'as' are s1, s2...). Up to 6 steps. Example: steps [{tool:'web_search',args:{query:'{{input.topic}}'},as:'find'},{tool:'extract_content',args:{url:'{{steps.find.results.0.url}}'}}]. Run it later with recipe_run, or publish it with recipe_publish. Cost: 1 credit per call.
