#GitHub Copilot

A customer's Excel tracker became a testable app in 25 minutes. Here's how Copilot Studio, Cowork, code apps, and GitHub Copilot compare.

I compared two finished apps built from the same brief, one with Claude Sonnet 5.5 and one with Claude Opus 5.5, screen by screen. Both work, and the gaps are specific.

AI Harness Helper brings your coding tool settings into one view, finds duplicate MCP servers, and estimates how much context your instruction files use.

Plan GitHub Copilot credit consumption with real-user pilots, measure savings alongside costs, and use budgets and focused tasks to manage spending.

Code apps let you build a React or Vue app in your own IDE and run it on Power Platform, with Entra ID sign-in, 1,400+ connectors, and DLP handled for you.

The Power Platform admin center still doesn't flag which Copilot Studio agents run on the GitHub Copilot harness. The isCLIAgent property does, and Microsoft has now published governance guidance built on it.

A 20-minute quickstart for customizing the GitHub Copilot app as a non-coder: instructions, agent skills, MCP servers, custom agents, and plugins.

Foundry Canvas puts model selection, toolboxes, guardrails, testing, and deployment in a Copilot side panel while leaving you the actual agent code.

The AI tools I use to design, ground, review, and ship vibe-coded projects, from Impeccable and Microsoft Foundry to MCPs and Power Platform Skills.

Set up GitHub Copilot to vibe code a blog, an app, or your own project. Learn the tools, agents, and skills; install Astro only for the blog example.

Field-tested lessons from shipping with AI: use plan mode, build reusable skills, choose models deliberately, and keep a reviewer in the loop.
