One of the strongest benefits of Slack app manifests is that application configuration becomes portable, reviewable, and reproducible. Slack explicitly recommends storing manifests in version-control systems such as GitHub, where collaborators can understand application setup and track configuration changes over time. A manifest can then be reused to create or configure apps consistently instead of manually reproducing settings through the web interface. This significantly reduces configuration drift between development, testing, and related application environments. A manifest is not the only mechanism for enabling bot functionality, does not eliminate OAuth authorization requirements, and does not automatically publish an application to the Slack Marketplace. Distribution and Marketplace publication remain separate lifecycle processes with their own requirements. Therefore, the version-controlled and repeatable configuration benefit described in B is precisely aligned with Slack's manifest documentation.
