Nex brings your Webex work and Codex tasks together.
Search collaboration history, prep the day from meetings and transcripts, and route approved work through a personal Nex bot while you stay in control of what gets posted back.
What It Does
Find the right Webex context
Search spaces, threads, files, recent conversations, and source links from inside Codex.
Prepare the day
Use hosted Daily Brief, meeting prep, participants, summaries, recordings, and transcripts when available.
Work from hosted state
Open tasks, meeting artifacts, transcript Q&A, and handoffs from the hosted Command Center.
Answer with sources
Use Webex, Atlassian, and Cisco GPK2 Confluence context to draft answers with useful citations.
Approve every public reply
Create your own Webex bot identity, route requests into a private queue, and approve replies before Nex posts back.
Install
Use the GitHub marketplace path first. The ZIP is available for machines where Codex cannot reach the private GitHub marketplace.
1. Add the marketplace
codex plugin marketplace add padmanak_cisco/webex-messaging-codex-plugin --ref main
codex plugin marketplace upgradeThis path only works if your GitHub account has access to the private source repository. If it fails, skip to the ZIP download.
2. Install the plugin
In Codex, open /plugins, choose Nex Plugins, and install Nex.
3. Sign in
Start a fresh Codex thread and select Nex from the plugin picker. Codex opens Webex sign-in for Webex tools and Atlassian OAuth for Confluence tools when each source is first used.
Update later
If you already installed the plugin from the marketplace, refresh it with:
codex plugin marketplace upgrade webex-codex-pluginsThen open a fresh Codex thread and select Nex again so Codex reloads the updated plugin tools and skills.
If GitHub marketplace access is unavailable, download the latest ZIP below and import or reinstall the local plugin bundle from /plugins.
The ZIP is generated from main and cached briefly, so it can take about a minute after a merge before the download reflects the newest changes.
ZIP download
Use the ZIP if marketplace install or upgrade fails with GitHub access errors such as
repository not found, authentication required, 403,
404, or if Nex Plugins does not appear after upgrade.
Download the ZIP anywhere, then open /plugins in Codex and choose the
local plugin bundle import option. If Codex has already detected the downloaded bundle,
select it there; otherwise browse to webex-messaging-codex-plugin.zip from
Downloads or wherever the file was saved.
Create Your Nex Digital Twin
Your digital twin is a Webex bot connected to hosted Nex and Desktop Codex. You or teammates can mention it with work; Nex creates a private task, and public replies still wait for your approval.
How the Digital Twin Handoff Works
Someone asks your twin
You or anyone in a Webex space with the bot can mention your digital twin with work for your Codex to handle.
Private handoff
Nex shows the task in your private queue and hosted Command Center.
Start Codex
Click Open in Codex to launch Desktop Codex with the hosted handoff prompt.
Approve the result
Codex marks the card as actioned, then Nex asks you to approve or reject the final reply.
1. Start setup in Codex
Open a fresh Codex thread with Nex installed and ask:
Set up my personal Nex botCodex will prepare a suggested bot name, username, and description for the Webex Developer Portal.
2. Create the bot
Nex opens the Developer Portal in your visible Chrome session so you can review the form before creating the bot. The Webex bot token is shown once after creation.
Keep the token out of chat and screenshots. Nex stores it in the hosted workspace secret store for the shared listener.
3. Verify the listener
Setup creates your private Nex Digital Twin Queue space and registers the
hosted listener. To check it later, ask:
