Use case
Standups, bugs, and decisions live in Slack. You want Codex to summarize threads and draft replies without losing context.
Outcome: Install the Slack plugin for channel access. Add a Slack notification hook if you want completion pings in a channel.
Install the Slack plugin and complete workspace authorization.
Ask Codex to summarize a channel or draft a reply.
Optionally install Slack notifications so finished runs ping your team.
Keep secrets out of chat — never paste API keys into Slack via Codex.
Copy a command, run it, restart Codex, then use the verify prompt.
Core — read channels and draft messages
$ npx codex-marketplace add openai/plugins/plugins/slack --pluginVerify
“Summarize unread messages in #engineering from today”
Optional — notify Slack when Codex finishes
$ npx codex-marketplace add am-will/codex-skills/hooks/aitmpl-codex/automation/slack-notifications --hookVerify
“Run a short task and confirm a Slack notification arrives”
Alternative — desktop ping with zero Slack setup
$ npx codex-marketplace add am-will/codex-skills/hooks/aitmpl-codex/automation/simple-notifications --hookVerify
“Ask Codex to finish a short task and watch for the desktop notification”
Only channels your OAuth / bot permissions allow. Private channels may need explicit invites depending on the Slack app config.
The plugin lets Codex read and draft in Slack. The hook pushes status when Codex finishes — different jobs.
