Agentic CLI customizations now in the usage metrics API
GitHub's changelog for September 17, 2026 carries the title "Agentic CLI customizations now in the usage metrics API." The entry states that customizations made to the agentic CLI are now surfaced in the usage metrics API. The provided source text consists of the title, the publication timestamp, and the page's typography and layout styling, with no additional body copy describing endpoints, fields, metric names, or rollout details. Because the excerpt is limited to the headline claim, the digest stays narrow: the change concerns the usage metrics API and the agentic CLI, and it is presented as a changelog update from GitHub. No version numbers, API schema changes, pricing, limits, or availability dates are stated in the source, so none are reported here. The only source-grounded consequence is that agentic CLI customizations are now represented in the usage metrics API, which is the scope the changelog title describes.
Developers pulling usage metrics from the API can now see agentic CLI customization data reported there, per the changelog title.
