Closes #1044

What changed

Selecting Grok and sending a message showed Claude could not finish the response. That string is the Claude decoder's fallback for an is_error result that has no result string. Grok's streaming-messages-json error result does not use that field. A signed-out turn on Grok 1.0.40 prints this and exits 1:

{"type":"result","subtype":"error_during_execution","is_error":true,"errors":["Not signed in. …"],"session_id":""}

The cause lives in errors. Tinycast now reports that text, and names Grok if both errors and result are empty. An empty session_id is ignored, so the cleanup call is not grok sessions delete "".

The same CLI also makes the route look ready when it is not. grok models exits 0 and still prints the catalog under You are not authenticated. Discovery treated any non-empty catalog as a login, so Settings offered Grok and the chat then failed with the Claude sentence. A signed-out banner is now the auth check; the catalog is still parsed, but it is not offered until the CLI is signed in.

Partial text is unchanged: Grok still reuses the Claude stream_event / text_delta shape.

Memory footprint

Not measured as a table. This machine has the Command Line Tools only, so the app was not launched. The change does not add a process, cache, or retained buffer. The only new string is the error text Grok already printed, and it dies with the turn.

Step Memory
Idle after launch not measured — no Xcode on this machine
Palette open not measured
Feature in use (peak) not measured
Palette closed, settled not measured

Leak-tested: not run. No new long-lived state.

Drawbacks

Sign-in detection is a banner match (not authenticated / not signed in) on grok models output, not a dedicated auth command. Grok 1.0.40 has no auth status. A future CLI that drops the banner and still exits 0 while signed out would look ready again.

errors wins over a result string when both are present. The captured failure has only errors.

Tests & validation

  • ./Scripts/run-tests.sh ai-provider-test — passed. New cases: the captured error_during_execution frame surfaces errors and drops an empty session id; a bare is_error result says Grok, not Claude.
  • ./Scripts/run-tests.sh installed-ai-test — the new signed-out catalog case passed. Two Cursor discovery assertions failed; they do not touch this diff and fail the same way when discovery locates a real agent instead of the stub.
  • Reproduced the wire payload with the flags Tinycast already passes (--prompt-file, streaming-messages-json, --deny *, --sandbox workspace, …) against /Users/iuri/.grok/bin/grok 1.0.40. Stdout was the errors result above; stderr was Not signed in.
  • xcodebuild was not run. xcode-select points at the Command Line Tools, and Xcode 26 is not installed. swiftlint is not installed either.

Tinycast requires the bug or feature to be agreed before code is written, so effort isn't
wasted on something that won't be merged. See
CONTRIBUTING.md.

To get this merged:

  1. Open an issue (or find the existing one) describing the change.
  2. Wait for it to be marked approved.
  3. Put Closes #<number> in this PR's description. It reopens on its own once the
    issue is approved, or reopen it yourself if the issue already is.

📝 Summary

Summary by CodeRabbit

  • Bug Fixes

    • Signed-out Grok accounts are no longer treated as ready when a model catalog is returned, and their models are not shown as available.
    • Grok errors now display the reported cause when available, with a fallback message when no cause is provided. Empty session IDs are ignored.
  • Documentation

    • Updated AI documentation to explain provider sign-in checks and Grok error handling.

Walkthrough

Grok model probing now checks authentication text as well as catalog contents. Grok stream decoding uses reported error details for failed result frames and provides a fallback when no cause is present.

Changes

Grok CLI Integration

Layer / File(s) Summary
Authentication and model probing
Tinycast/Features/AI/Model/InstalledAI.swift, Tinycast/Features/AI/Service/InstalledAIManager.swift, Tests/installed-ai-test.swift, Tests/ai-fixtures/installed-cli-stub.js, docs/features/ai.md
Grok sign-in detection checks normalized output for authentication warnings. The model probe returns a ready status and catalog only when signed in and the catalog is non-empty. Tests and the CLI stub cover signed-out discovery. The documentation describes the authentication check.
Result error decoding
Tinycast/Features/AI/Model/InstalledAIStream.swift, Tests/ai-provider-test.swift, docs/features/ai.md
Grok result frames use non-empty errors entries, then result text, then a fallback message. Tests cover reported and missing causes, empty session IDs, and incomplete frames. The documentation describes the error format.

The Grok discovery test can depend on a developer’s installed CLI instead of its fixture. Pin executable discovery before merging so the relevant test runs reliably.

Grok 1.0.40 still exits 0 from grok models while signed out, and an error result omits result and puts the cause in errors. The shared Claude decoder then showed Claude could not finish the response.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Make Grok discovery use the fixture executable.

If login-shell discovery selects an installed grok, this test probes that command instead of the fixture. The result then depends on the machine’s Grok sign-in state and can fail despite correct code. Inject or otherwise pin executable discovery for this test. As per path instructions, “Tests must be deterministic: inject clocks and temp directories, no network, no sleeps for timing.”
