adoption — agent count
Number of agents in the Nerq index using each framework
average trust score
Mean trust score of agents using each framework (0-100)
methodology
Framework association is determined from the frameworks array in the Nerq agent database.
An agent is counted under a framework if that framework appears in its declared dependencies, metadata, or detected integrations.
Trust scores are the Nerq Trust Score v2 — a composite of security practices, compliance, maintenance activity, community trust, and ecosystem compatibility.
