conf/config-dev.yaml mirrored the production default, so a local run had no builder entry in the menu and no way to create builds without editing the file. Enable it there: the development config is the one used when running against a local builder. Verification: - helm/conf not affected; loaded by `go run . server -c conf/config-dev.yaml`

sigma-cli: a single binary that operates a remote Sigma server over the REST API. It covers namespaces, repositories, tags, artifacts, members, and users. See CLI & AI Agents.- External REST API skill:
tools/skill/sigma-api-operatorpackages a reusable skill andswagger.yamlso CLI agents such as Claude Code or Copilot CLI can discover Sigma APIs and operate resources through HTTP requests, including the areas the CLI does not wrap yet.
