# Feature catalog — lerna/lerna

Scanned commit ce3e38f2889b26573f1b38cfb487546903292158 (2026-10-02). Generated by codevetter codevetter 1.15.0 on 2026-10-02.

Source inspection; upstream code and tests were not executed.

The registered CLI covers workspace setup, package inspection, task execution, cleanup, importing history, and releases. Shared filtering supports package scopes, exclusions, changed-package selection, and dependency expansion where commands expose those options. Versioning and publishing have distinct modes and side effects. Legacy package-management names remain registered only to explain their removal.
- init generates lerna.json, adds Lerna as a development dependency, supplies workspace configuration for a new repository, and supports dry-run previews; create scaffolds package files and optional CLI files. — [libs/commands/init/src/index.ts#L85-122](https://github.com/lerna/lerna/blob/ce3e38f2889b26573f1b38cfb487546903292158/libs/commands/init/src/index.ts#L85-L122) [libs/commands/init/src/index.ts#L136-210](https://github.com/lerna/lerna/blob/ce3e38f2889b26573f1b38cfb487546903292158/libs/commands/init/src/index.ts#L136-L210) [libs/commands/create/src/index.ts#L183-206](https://github.com/lerna/lerna/blob/ce3e38f2889b26573f1b38cfb487546903292158/libs/commands/create/src/index.ts#L183-L206)
