    Subgraph Migration · enviodev bundle
    This skill should be used when the user asks to "migrate from subgraph", "convert subgraph to hyperindex", "migrate from thegraph", "port subgraph", "convert subgraph handlers", "migrate assemblyscript to typescript", or mentions TheGraph, subgraph migration, subgraph.yaml conversion, or converting from TheGraph to Envio. For core HyperIndex development patterns, refer to the hyperindex-development skill.
