In your AI assistant
datrix in your AI assistant
The same two jobs — create a matrix, work with a matrix — done from your own assistant (Claude, ChatGPT, or Antigravity). The built-in assistant is the quickest way to start; this is the more flexible and powerful way to work, with all of your assistant's reasoning brought to your decisions.
Do the one-time Connect below, then either path works.
One time
Connect your assistant
Links an outside assistant to your datrix account so it can actually build and save matrices.
Until you connect, your assistant can talk about a decision but can't create or save anything in datrix — you'd just be having an ordinary chat. Connecting is the step that turns the conversation into a real, saved matrix.
That installs the plugin. You won't be asked to sign in yet — that happens the first time you actually use datrix. The first time you run /decide (or accept your assistant's offer to capture a decision), Claude opens your browser to sign in to datrix and approve access. Approve once and you're connected from then on.
/plugin marketplace add lockstride/claude-marketplace/plugin install dmatrix@lockstride-marketplace
Claude Desktop or claude.ai instead?

OpenAI 
Antigravity How to know it worked
- 1The plugin is installed. In Claude Code, run /plugin. datrix should appear in the list as installed and enabled. That's all you need to get started — the account connection happens on its own the first time you use it.
- 2Your account is connected. Sign-in isn't part of install; it happens on first use. The first time you run /dmatrix:decide — or accept your assistant's offer to capture a decision — you'll be sent to your browser to sign in to datrix and approve access. You only do this once.
- 3Confirm and manage it. After you've signed in, your assistant shows up in datrix under Settings → Connected Clients — the same place you go to disconnect it later. Give it a moment; the list refreshes on its own.
Not seeing it? If /plugin doesn't list datrix, re-run the two install commands. If it's installed but nothing's saving to your account, you most likely haven't finished sign-in yet — run /decide and complete the browser approval.
Once connected, both paths below work — and mix freely with anything you do inside datrix.
Create
Create a matrix — from a conversation
The same job as Create a matrix, started from your chat instead of the datrix screen.
- Starttype /dmatrix:decide (in Antigravity, /decide). Your assistant also offers on its own when it notices you weighing options.
- Describe / shapeanswer as it draws out your options, criteria, and scores.
- Savethe finished matrix saves straight to your datrix account.
This isn't only for decisions you're making right now. Scroll back to something you talked through earlier — yesterday, last week, anywhere in the thread — and run /dmatrix:decide to turn that past conversation into a matrix in one step. No copy-paste, no starting over. It's one of the fastest ways to get a real, structured decision out of a chat you've already had.
Work with
Work with a matrix — from your assistant
The same job as Work with your matrix, run from your assistant with the full matrix in context.
- Openpoint your assistant at a matrix you already have; its full context — options, criteria, priorities, scores, rationale — becomes live in the conversation.
- Ask for a changetalk through trade-offs, ask questions, draft a recommendation, or have it update the matrix. Every change lands back in datrix.
keep both windows open side by side and watch your assistant build and manipulate your matrix in real time inside the datrix interface.
