Slack Chat OS plugin for [Paperclip](https://github.com/paperclipai/paperclip). Turns Slack into a bidirectional agent command center - notifications, approvals, multi-agent threads, voice-to-task pipelines, custom workflow commands, and proactive agent suggestions.

Built on the Paperclip plugin SDK and the domain event bridge ([PR #909](https://github.com/paperclipai/paperclip/pull/909)).

Why this exists

Multiple Paperclip users asked for notifications on the same day the plugin system shipped (2026-03-14):

"is there a way to have codex/claude check paperclip to see when tasks are done without me prompting it?" - @Choose Liberty, Discord #dev

"basically to have it 'let me know when its done'" - @Choose Liberty, Discord #dev

"can claude code check paperclip to see when tasks are done" - @Nascozz, Discord #dev

@dotta (maintainer) responded: "we're also adding issue-changed hooks for plugins so when that lands someone could [make notifications]." The event bridge ([PR #909](https://github.com/paperclipai/paperclip/pull/909)) shipped that same day. @dotta also asked for "someone to make a plugin that's a totally separate package" to validate the DX. @Ryze said "Really excited by the plugins. I had developed a custom plugin bridge that I will now deprecate and migrate over to the new supported plugin system."

This is that plugin.
