Anthropic's ant CLI 1.30.0 Adds `ant apply`, Turning Agents and Skills Into Checked-In Infrastructure

Anthropic Release Notes·medium signalXBlueskyLinkedInCopy link

Version 1.30.0 of the `ant` CLI, released September 3, 2026, introduced `ant apply`, which creates and updates agents, environments, skills, memory stores and deployments from declarative files in a repository. The flow mirrors Terraform: define resources, run apply, review the generated plan, and commit a `claude-lock.json` lockfile so local machines and CI resolve to the same versions. This is the first time Anthropic has shipped a plan-and-lockfile model for agent configuration rather than leaving it to per-project scripts.
