The context · June 2026
Anthropic introduced Claude Sonnet 5 in June 2026, describing capabilities for work across coding tools, browsers and other software environments. [1]
A cheap action can start an expensive chain
An assistant may make several tool calls, retry a failed step and produce a result that still requires investigation. Looking only at the price of one model request misses this accumulated effort. The useful unit is a completed, accepted task.
Bound the attempt
Give a workflow a limit on time, tool use and repeated failures. Define the point at which it should return its findings to a person. A useful handover explains what succeeded, what failed and what evidence is available, so the reviewer does not have to start again.
Make stopping a normal outcome
Some requests lack enough information or require authority the assistant should not hold. Treat these as explicit workflow states rather than errors to conceal. A dependable assistant should be able to stop with a useful explanation. That behaviour matters as much as its performance on a successful demonstration.
