From b8c72c5665ec8f882b8f6b558df91607896dad61 Mon Sep 17 00:00:00 2001 From: saravmajestic Date: Tue, 4 Aug 2026 01:47:22 +0000 Subject: [PATCH 1/2] feat: [AI] add cli_context to browser auth URL for PostHog session correlation - Append base64url-encoded cli_context param to the register URL opened by AltimateAuthPlugin. Context blob: { v, machine_id, cli_version }. - machine_id is the existing stable UUID from ~/.altimate/machine-id (already in every App Insights event). If the file is missing, log a debug message instead of silently omitting. - Export buildCliContext() and add 3 unit tests covering: valid context, missing machine-id file, and whitespace trimming. --- .../opencode/src/altimate/plugin/altimate.ts | 25 ++++++++- .../test/altimate/altimate-plugin.test.ts | 51 +++++++++++++++++++ 2 files changed, 75 insertions(+), 1 deletion(-) create mode 100644 packages/opencode/test/altimate/altimate-plugin.test.ts diff --git a/packages/opencode/src/altimate/plugin/altimate.ts b/packages/opencode/src/altimate/plugin/altimate.ts index eaa26366a..33ce890b5 100644 --- a/packages/opencode/src/altimate/plugin/altimate.ts +++ b/packages/opencode/src/altimate/plugin/altimate.ts @@ -5,6 +5,11 @@ import open from "open" import { AltimateApi } from "../api/client" // altimate_change — onboarding telemetry for the gateway sign-in funnel import * as OnboardingTelemetry from "../telemetry/onboarding" +import fs from "fs" +import os from "os" +import path from "path" +import { InstallationVersion } from "@opencode-ai/core/installation/version" +import { Log } from "@/altimate/util/log" /** * Why a failure reason is attached at the rejection site rather than inferred from the message: @@ -47,6 +52,23 @@ const DEFAULT_WEB_URL = "https://app.myaltimate.com" // deliver. const DEFAULT_API_URL = "https://api.myaltimate.com" +const log = Log.create({ service: "altimate-plugin" }) + +// Build a base64url-encoded context blob so the frontend can correlate this +// browser auth session with CLI telemetry.
