Microsoft just announced that the Power Pages agentic coding tools GA milestone is here. The plugins for GitHub Copilot CLI and Claude Code are now generally available, after a preview that landed earlier this year. You can read the full announcement on the Power Platform blog.
This is the part I have been waiting for. Power Pages site building is moving out of the maker portal and into the terminal where pro devs actually live. That changes who can credibly own a Power Pages project inside a large org.
What it actually does
The plugin sits inside GitHub Copilot CLI or Claude Code as an extension. You describe the site in natural language. The agent generates the scaffolding, sets up Dataverse tables, wires up the Web API, configures table permissions, and deploys the site.
The important bit is the grounding. The plugin is not asking the model to guess at Liquid syntax or invent table names. It reads your actual environment, your existing tables, your site settings, your authentication setup. The output lands in your repo as files you can diff, review, and commit.
You get the standard pro-dev loop. Branches. Pull requests. CI checks. Code review. The site definition is text, the agent generates text, and Git handles the rest. No more configuring half the site in the maker studio and the other half through manual file edits and praying the two stay in sync.
Why moving to GA actually matters
Preview features do not get deployed to production at most enterprises I talk to. Security reviews block them. Procurement blocks them. Internal policy blocks them. GA flips that switch.
More importantly, GA means the API contract is stable enough that you can build CI around it without expecting it to break next month. That is the difference between a fun side experiment and something a team commits to as a standard delivery pattern.
The bigger shift is cultural. Power Pages has always had a split personality. The studio handles the front-end click work, but the layer underneath, Liquid templates, Web API calls, table permissions, plugin logic, is real code. I wrote about this when the server-side skills landed. The maker portal hid the code layer behind a UI that pro devs did not want to touch and citizen devs could not safely change.
Pulling the build process into Copilot CLI or Claude Code lets a pro dev own the whole site end to end without leaving the terminal. That is a real unlock for the kind of internal portal work that has been stuck between teams for years. If you are also thinking about how multi-agent orchestration patterns in Copilot Studio fit alongside this kind of terminal-driven build loop, the two are worth thinking about together.
The trade-off is honest. This is not for citizen devs. If your maker has never opened a terminal, this is not their tool. The maker studio is not going away, and it should not. But for the portal projects where someone wanted to use Git, code review, and a real deployment pipeline and could not, the path now exists.
What I would do with it this week
I would pick the smallest internal Power Pages site I can find. Something with two or three tables, an authenticated user experience, and a form that writes back to Dataverse. Nothing customer-facing. Nothing with sensitive data.
Install the Power Pages plugin in GitHub Copilot CLI. Point it at a dev environment that mirrors a real one but is safe to break. Ask it to scaffold the site from a short description and let it generate the Dataverse tables and Web API config. If you want the agent to do more than scaffold, Dataverse knowledge sources and agent feedback loops are worth wiring in at this stage.
Then I would intentionally break something. Change a table permission by hand in the maker studio. Re-run the agent. See how it handles drift. That is the failure mode that will hurt in production, and you want to know the answer before you commit to this for a real project. I have learned the hard way that the demo path always works. The drift path is where tools live or die.
I would also run the same prompt through both the Copilot CLI plugin and the Claude Code plugin and compare the output. Same site, same description, two agents. The deltas will tell you a lot about which one to standardise on.
For anyone running portal projects inside a large org, this is the week to actually try it. The Power Pages docs have the setup steps and the plugin is a clean install.
The terminal is becoming a real surface for Power Platform work, and I am here for it.
