## From README

Editing an Existing Application When modifying an existing Pigment application (adding blocks, changing formulas, restructuring dimensions, reorganizing folders, deleting unused objects, or any combination), follow the two-stage workflow below. --- Stage 1 — Plan During Stage 1, do NOT call any modeling tool and do NOT load any execution skill. Loading another planning skill is allowed. Use only discovery tools (tool:searchmetricsandlists, tool:searchfolders, tool:searchtables, tool:semanticsearch, tool:getmetricdependencies, tool:getdatadependencytree, tool:listissues, tool:calendarget, tool:getapplications, tool:searchboards) and the sections below to produce the spec. Discover the current state Map the relevant portion of the application before deciding anything. Do not rely on assumptions.
