description: >-
  Adobe ships no general-purpose CLI for the Reactor API — there is no
  `reactor` binary that lists properties or publishes libraries. What Adobe
  does ship is a four-command extension-development toolchain, each a separate
  npm package with its own bin, that walks an extension from skeleton to
  released. Everything else is expected to go through the API or the UI.
api_cli: false
api_cli_note: >-
  No first-party CLI covers the Reactor management surface. An operator
  automating property, rule, library or build work uses @adobe/reactor-sdk or
  raw HTTP.

  Three of the five tools were last published before 2026 — scaffold in
  February 2023, releaser in October 2024, uploader in December 2024 — while
  the Reactor API contract they target was updated for the 2026 surface. Only
  the sandbox and the packager have shipped recently.
