Runs and spans
DesignThe run as a system: model calls, tools, retries, cost, and outcomes under one identity.
#Reading a run as a system
A production incident is rarely one bad call — it is a shape. A retry storm in one tool span drives most of a cost delta; a model span may be entirely innocent. Telemeter keeps the spans connected so the shape is legible, and so a recommendation can point at the span that actually caused the bill.
