Slack CLI v4.12.0 lets coding agents read its CLI skill directly with slack skill or slack --skill. The instructions match your installed CLI version, and you don't need to install the Slack Skills Plugin.

For Enterprise organizations, slack install and slack run now stop before creating an app if its manifest doesn't set orgdeployenabled to true. The CLI explains the fix; previously, the app installed but never received events.…

Slack's new Block Kit layout block lets you arrange content in rows and side-by-side items within a message or view.

Existing section, image, actions, table, and other blocks can go inside its layout items. Choose narrow, standard, or wide sizing rather than specifying pixels. The grid stays inside a single block, and older Slack clients render the fallback blocks you supply.

You can now create and update Slackbot skills through Slack's Web API, including keeping their instructions in source control and deploying changes from CI.

Create a skill from markdown instructions or a canvas you own. Markdown-based skills start invite-only; converting a canvas keeps its sharing.

Enterprise org admins can publish skills to the organization's catalog. Publishing can share the canvas org-wide, but people still need the skill in their library to use it.…

Slack CLI 4.11.0 makes password-free sign-in the default for slack sandbox create. Unless you pass --password, you'll sign in to the new sandbox through an email link.

This release also stops trusting the compromised eMudhra certificate authorities. The CLI now uses Go 1.27.3, and local development requires Deno 2.9.8 or later. slack doctor flags older versions as unsupported. New deploys and re-deploys to Run on Slack infrastructure use Deno 2.9.8.

Slack Code lets agents create dedicated channels from existing conversations for work that needs more than a quick reply. People and agents can discuss changes, follow progress and inspect the work in the same channel.

Apps can pin up to five context items, such as a repository, branch or CI status, and add tabs for code diffs, canvases or HTML output. When an app supplies the original channel and message without overriding privacy, the code channel matches the source channel’s privacy.…

Slack CLI v4.9.0 lets you opt an app into app-level token rotation through the settings.appleveltokenrotationenabled property in its manifest.

It also handles invalid logins more cleanly. An expired login with an invalid refresh token now prompts you to run slack login again. The slack activity --tail and slack run commands exit with an authentication error when the login token becomes invalid.
