 ## Prerequisites
 
-- A repository on your GHE Cloud data residency instance (e.g., `yourorg.ghe.com`)
-- The `gh aw` CLI extension **v0.61.1 or later** (`gh extension install github/gh-aw`)
-- Copilot enabled for your enterprise
-- The `gh` CLI authenticated with your GHE instance:
-  ```bash
-  gh auth login --hostname yourorg.ghe.com
-  ```
+You need a repository on your GHE Cloud data residency instance (for example, `yourorg.ghe.com`), `gh aw` **v0.61.1+** (`gh extension install github/gh-aw`), Copilot enabled for your enterprise, and `gh` authenticated against your GHE host:

 ## Troubleshooting
 
-If the workflow fails, start by using the Copilot CLI to help diagnose the issue.
+If the workflow fails, start with the Copilot CLI on your local machine. First confirm authentication:
 
-### Debugging with Copilot CLI Locally

-The fastest way to diagnose failures is to use the Copilot CLI interactively from your local machine. This lets you confirm Copilot can authenticate against your GHE instance and then use Copilot itself to help debug workflow failures.

+GH_HOST=yourorg.ghe.com gh auth status

-3. **Select the agentic-workflows skill** — when Copilot starts, invoke `agentic-workflows`.
+Invoke the `agentic-workflows` skill and ask it to run and debug the workflow, for example:
 
-4. **Ask Copilot to run and debug the workflow** — trigger the workflow, wait for it to complete, and then ask Copilot to analyze the results. For example:
-   ```
-   Run the repo-assist workflow and check if it succeeds.
-   If it fails, help me debug the failure.
-   ```

+Run the repo-assist workflow and check if it succeeds.
+If it fails, help me debug the failure.

-Copilot has access to your workflow files, run logs, and the `gh aw audit` tool, so it can inspect failures end-to-end and suggest fixes.
+Copilot can inspect your workflow files, run logs, and `gh aw audit` output to help narrow down the failure.
