connector-slack is an agent skill published by caffeinelabs. It lives in the caffeinelabs/skills repository, which has 2 GitHub stars and is licensed under Apache-2.0; we last read it on 2026-10-22.
EXPERIMENTAL, UNTESTED recipe for posting messages to a Slack workspace from a Caffeine canister via the `slack-client` mops package (Slack Web API). Use it when the user wants their app to send a message to a Slack channel — "post to Slack", "notify a channel", "send a Slack message", or equivalent. The client is a pre-release 0.1.0 drop (bot `xoxb-` or user `xoxp-` token): its request path is verified against the live Slack API (a real message posts), but the success-response decode is not yet runtime-confirmed, so treat it as a starting point and do NOT present Slack as a fully supported platform feature yet. Hand-rolling `ic.http_request` calls to `slack.com/api` is still the wrong move — prefer the generated client so bearer auth, percent-encoding, and JSON parsing come for free.
Install
skills is a generic installer for any repository of Claude agent skills -- it reads caffeinelabs/skills’s own structure rather than assuming one, the same way this page reads the skill’s own SKILL.md rather than assuming a format.
npx skills add caffeinelabs/skills
