@@ -58,6 +58,7 @@ Aspire CLI collects the following data:
 | 13.5 | Coding agent detection. | When the CLI is invoked from a known coding agent environment (such as GitHub Copilot, Claude, Cursor, or others), the detected agent name is recorded. Only the known agent name is sent — no environment variable values or other identifying data are included. This data point is omitted entirely when no known coding agent is detected. |
 | 13.6 | Coding agent detection: GitHub Copilot app. | The detector now separately identifies the GitHub Copilot app (the desktop GitHub application acting as an AI agent) as `copilot-app`, in addition to `copilot-cli` when the underlying Copilot CLI environment variables are also present. |
 | 13.5 | AI agent skill usage. | Recorded only for Aspire's own skills and tools. See [AI agent skill usage data](#ai-agent-skill-usage-data). |
+| 17.0 | CLI installation source. | Identifies how the running CLI was installed: `script` (the bash or PowerShell installer), `winget`, `npm`, `dotnet-tool`, `brew`, `mise`, `nix`, `pr`, `localhive`, or `unknown`. This is independent of the CLI's effective release channel and lets Microsoft understand usage by installation mechanism. No sidecar strings or installation paths are sent — only the matched, known source value. |
