Build your own AgntUX plugin.
AgntUX already covers many popular data sources — but if the tool you live in isn't there yet, you can add it yourself. agntux-build walks you through it. No coding required.
What it does
You describe. It builds.
You describe the system you want AgntUX to support. agntux-build figures out the rest — connects to the system, designs the screen, builds the plugin, and tests it against your real data.
When it's working the way you want, you submit it back so every other AgntUX user benefits too.
Before you start
Four things to have ready.
AgntUX installed and set up
The AgntUX app installed, signed in, and through first-run setup — it must be running to deliver your finished plugin. Download AgntUX.
The tool you want to add
The connector for your target system (Linear, Notion, Jira, etc.) available in Claude. Most popular tools are already in the connector marketplace.
About an hour
Plus patience for 3–5 rounds of testing. That's normal — not a sign anything went wrong.
How to start
Type one command in Claude Code.
The first time you run it, AgntUX asks for your name and email and walks you through the Developer Certificate of Origin — a short, standard open-source agreement confirming the work is yours to contribute. It only asks once. After that, just describe the system you'd like covered.
What happens next
Seven steps, all conversational.
You'll be asked to confirm each step. Nothing changes on your computer without your OK.
Marketplace check
If a plugin for your system already exists, AgntUX installs that one instead. No duplicates.
Connect
AgntUX authorises the connector for your system.
Plan in plain language
“Here's what your plugin will be able to read, and here's the button people will press to take action.”
Design the screen
You'll see a live preview. Edit until it feels right.
Build and test
Happens on your machine. Nothing extra to start, nothing extra to install.
Iterate against real data
AgntUX runs your plugin against your real data right in the conversation and shows you what it would surface. You react, it adjusts — usually 3–5 rounds. No installing, no copy-pasting.
Submit
When everything feels right, AgntUX finalizes your plugin and the AgntUX desktop app syncs it to the team automatically. Nothing to download, attach, or send.
Track it
Watch it move through review.
The moment you submit, your plugin shows up in the AgntUX desktop app under the Built by you tab — so you can see exactly where it stands, live, with nothing to refresh.

Reviewed and won't be merged.
Fix mode
Fixing an existing plugin.
If you've used a plugin and hit something specific, run the same command — /agntux-build:build — and describe what went wrong. AgntUX switches into fix mode and walks the same flow with a smaller scope.
