AgentEKG is a set of QuantaCanvas card types that receive Claude Code hook events via QuantaHub. Drop them on your canvas alongside your other agent tools — no separate deployment required.

Aggregated input, output, cache creation, and cache read tokens. Model-aware cost calculation, cache savings percentage, error rates, active session count, and top tools by call count. Pro+.
