CLI half of PLA-498 — sends the client OS so the backend can put it on the signup events and forward it to the CRM.

What changes

  • src/utils/client-os.ts (new) — X-Hivemind-OS, darwin→macos, win32→windows, linux→linux. Any other platform omits the header rather than inventing an other bucket, matching how hivemindInstallIDHeader() degrades.
  • src/commands/auth.ts — spread into the five places that already spread deeplakeClientHeader(): apiGet / apiPost / apiDelete, requestDeviceCode, pollForToken.

Why it rides the authenticated helpers, not just the device endpoints

signup_completed fires from whichever request provisions the user. That is trackDeviceFlowAuth at /auth/device/token only when the token carries an email claim; otherwise it is the middleware, on the CLI's first authenticated call — GET /me inside saveCredentialsFromToken, which runs before listOrgs.

A header on the two device endpoints alone would leave that path with no OS. sends X-Hivemind-OS on the first authenticated call, GET /me asserts on the URL rather than the helper, so moving /me off apiGet fails the test instead of silently consuming the one-time signup capture without an OS.

Note on vocabulary

Two other producers already send an OS and disagree with each other — hivemind.ps1 sends Windows, hivemind.sh (deeplake-ui#350) sends raw uname -s. The canonical mapping therefore lives at the backend boundary (normalizeOS in #334); this CLI sends the canonical name so it is not a third dialect.

Run result

 Test Files  3 passed (3)
      Tests  79 passed (79)
   Duration  321ms

tests/claude-code/auth.test.ts (70) + client-os.test.ts (new, 5) + install-id.test.ts, all green. tsc --noEmit clean on the touched files (the 4 tree-sitter errors are pre-existing, missing native optional deps in the worktree).

End-to-end is NOT verified. PLA-498 requires a real install on macOS, Linux and Windows producing an event carrying the correct OS, quoted from the real payload — that needs #334 deployed, this released, and a Windows machine. Unverified, stated as such.

Ticket: PLA-498

Summary by CodeRabbit

  • New Features

    • Authentication and API requests now include the client’s operating system on macOS, Windows, and Linux.
    • Existing authentication and request headers remain preserved.
    • Requests from unsupported platforms continue without an operating-system identifier.
  • Bug Fixes

    • Improved operating-system identification during authentication and API communication.
    • Added safeguards to ensure only supported operating-system values are sent.

📝 Walkthrough

Walkthrough

The change adds platform-to-OS mapping helpers and propagates the optional X-Hivemind-OS header through authentication requests. Tests cover supported and unsupported platforms and header forwarding across authentication flows.

Changes

Client OS Header

Layer / File(s) Summary
OS header helper
src/utils/client-os.ts, tests/claude-code/client-os.test.ts
The helper maps darwin, win32, and linux to backend values. It returns no header for unsupported platforms. Tests cover exact mappings, header omission, and real platform behavior.
Authentication request wiring
src/commands/auth.ts, tests/claude-code/auth.test.ts
Authentication requests include the OS header when available. Tests cover device-code, authenticated API, and /me requests.
Windows smoke validation
.github/workflows/ci.yaml
The Windows smoke job runs client-os.test.ts against the real Windows platform mapping.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 0e7eb

The CLI now sends a coarse operating-system value on several authenticated requests, not only during signup. This has limited security impact because the value is fixed and locally derived, but the broader metadata disclosure and its backend retention or forwarding should be confirmed before or alongside merge.

Assert the exact output for every platform.

Line 46 accepts any allowlisted value. If sunos maps to "linux", this test passes although unsupported platforms must return "". Use a platform-to-expected-value table and assert toBe(expected) for each entry.

As per path instructions, tests/** must prefer specific values over generic substrings.

Both CodeRabbit findings addressed in 0e7ebf8. Same defect in both places — assertions that looked stronger than they were.

client-os.test.ts:67 (actionable)toBeTruthy() accepted any non-empty string, so the Windows runner would have gone green on a value of "macos". That assertion is the entire reason this file is in the windows-smoke CI leg, so the leg was proving nothing. Now asserts the exact per-platform value, and toEqual({}) on an unsupported platform.

client-os.test.ts:46 (nitpick) — agreed, and not really a nitpick: v === "" || allowlist.includes(v) passes when a platform maps to the wrong allowed name. sunos -> "linux" would have looked fine while the backend recorded a confident lie. Replaced with a platform-to-expected table asserting toBe(expected) per entry, unsupported platforms included.
