It also covers memory stores and deployments, writing a claude-lock.json lockfile so later runs update existing resources instead of duplicating them.
Version 1.30.0 of the ant CLI adds ant apply, a command that creates and updates Claude API resources, agents, environments, skills, memory stores, and deployments, from files kept in a repository.
Each resource is described in a file, an agent as a Markdown file with YAML frontmatter, for example, and running ant apply prints a plan of what will change before asking for approval. The first run writes a claude-lock.json lockfile recording each resource's ID; committing that file lets later runs, on a developer's machine or in CI, update the same resources instead of creating new ones.
Resources can reference each other by file path instead of by ID, so an agent can list a skill or another agent it depends on, and ant apply resolves them in dependency order. In CI, the docs describe running ant apply --yes on the default branch after merge, and ant apply --dry-run to print the plan on pull requests without changing anything.
