Simon Willison shares his experience using AgentsView to track token usage across coding projects. He explains how he reverse-engineered the tool to set custom pricing for Claude Fable 5, which wasn't yet in its database. Willison includes a visualization of his current Claude Fable 5 usage across projects.

AgentsView, a tool built by Wes McKinney for tracking token usage across local coding agents, doesn't yet include pricing for the newly released Claude Fable 5 model. A workaround involves manually setting custom prices in AgentsView, which can then visualize usage as a treemap across different local projects.
