#Agents

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.

I had an agent build six demo apps in Copilot Studio in one day, then wire one to live energy data through custom connectors. Here's what review taught me.

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.

Estimate Copilot Studio agent costs from business tasks, measure cost per successful outcome, and refine production budgets with observed credit consumption.

What Azure SRE Agent is, what setup actually looks like, and what happened when I pointed it at my own repo, my Application Insights telemetry across Dataverse, Copilot Studio, and Foundry, and then asked it for a health check on everything at once. Plus what connecting an incident platform buys you — autonomous mitigation, a verification loop, and a handoff straight to the GitHub Copilot coding agent — the five switches worth flipping that you don't get turned on by default, and what the newly published Zero Ops framework recommends, including the two governance layers above per-tool Allow and Ask and three details worth verifying against the current docs.

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.

Disabling public network access removes the Foundry portal's Teams publish button. Here's the REST path that replaces it and the inbound design you now own.

Turning on authentication breaks the Copilot Studio SDK with EnvironmentSettingViolation. Here's why Direct Line and a server-side token exchange are the fix.
