What is Document360?

After opening the knowledge base to machines, Document360 turns on its own furniture

Document360 ships monthly and hit 12.8.5 with a portal-interface release rather than a platform one. The top and left navigation bars were redesigned around a single dropdown that moves between projects, workspaces and languages instead of three separate menus, rolling out in phases. Alongside it, a Manage labels page finally makes labels deletable, groupable and countable by usage, and article status icons became dual-tone so a published article carrying an active draft reads at a glance.

What is Slack?

Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.

Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.

Document360 vs Slack: editorial side-by-side

D6.3

After opening the knowledge base to machines, Document360 turns on its own furniture

◆ Current state

Document360 ships monthly and hit 12.8.5 with a portal-interface release rather than a platform one. The top and left navigation bars were redesigned around a single dropdown that moves between projects, workspaces and languages instead of three separate menus, rolling out in phases. Alongside it, a Manage labels page finally makes labels deletable, groupable and countable by usage, and article status icons became dual-tone so a published article carrying an active draft reads at a glance.

◆ Where it's heading

The arc has run outward, then inward, and has now arrived at the portal's own information architecture. First the knowledge base was made safe for programmatic and agent access through the API v3 rebuild; then the gaps that serialise human teams were closed with co-editing and pre-publish checks; now the surfaces people navigate all day are being rebuilt for legibility. The quietest line in this release points somewhere else: an AI chatbot's content source dropdown now offers None, so a chatbot can be configured without the knowledge base behind it at all.

◆ Prediction

Expect the taxonomy work to continue past labels, since the one-time prompt to organise flat labels into groups implies a project-wide cleanup Document360 wants finished. The phased navigation rollout should complete before the next feature layer lands on top of it.

6.3

Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.

◆ Current state

Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.

◆ Where it's heading

The install requirement moving back up is a distribution decision arriving in the middle of a platform push, and the two point the same way. Slack is making it easier to build agents and harder to list one, which favours developers who already have distribution — existing workspace tools and vendors — over a new app hoping the Marketplace supplies its first users. Combined with the assistant deprecation and the Agent Sessions API, the platform is narrowing on one agent surface and one class of builder rather than widening the funnel.

◆ Prediction

The threshold is described as a return from a temporary lower bar rather than a new policy, so the open question is what replaces the Marketplace as the discovery path for an app that cannot reach ten workspaces on its own. These entries do not answer it.
