• The catch block message still says "Failed to retrieve GitHub PAT from KeyVault", but this try block now retrieves multiple secrets (GitHub PAT + CAPI integration id + CAPI HMAC). Update the error text (and ideally the preceding Write-Host) to reflect all required secrets so failures are actionable.

    try {
        Write-Host "Retrieving GitHub PAT from KeyVault $vaultName secret $secretNameGhPAT"
        $pat = az keyvault secret show --vault-name $vaultName --name $secretNameGhPAT --query value -o tsv
        $capiId = az keyvault secret show --vault-name $vaultName --name $secretNameCAPIID --query value -o tsv
        $capiHmac = az keyvault secret show --vault-name $vaultName --name $secretNameCAPIHMAC --query value -o tsv

        if (!$pat) {
            throw "Secret $secretNameGhPAT not found in KeyVault $vaultName."
        }

        $env:GITHUB_MCP_SERVER_TOKEN = $pat
        $env:CAPI_INTEGRATION_ID = $capiId
        $env:CAPI_HMAC_KEY = $capiHmac
        # Log the secrets as secret variables to avoid exposing them in logs
        if ($pipelineRun) {
            Write-Host "##vso[task.setsecret]$pat"
            Write-Host "##vso[task.setsecret]$capiId"
            Write-Host "##vso[task.setsecret]$capiHmac"
        }
    }
    catch {
        throw "Failed to retrieve GitHub PAT from KeyVault: $_"
    }
