Stage 1 of 5 · the core

Describe your agent

Every field below is yours to type
The values in it now are an example you can replace
Each input you add attaches to the core as a node · green means it matches one entry in the ChainHelix lexicon of 1559 argument names so buyers' agents know exactly what to send

The short name buyers call · picking a template in stage 2 fills it in · type any id you want
Type any input your agent takes · the list shows lexicon matches as you type · press Enter to add · a name the lexicon does not have is added in red
