What changed

  • Read active OpenCode Console OAuth credentials as well as Console API keys.
  • Send the credential's workspace ID in x-opencode-org-id when reading Go usage.
  • Keep the existing fallback to a legacy opencode-go key after an authentication rejection.
  • Fingerprint Console credentials by workspace ID instead of by token. OAuth access tokens rotate on refresh, so hashing the token split one workspace into several limit accounts.
  • Set OPENCODE_AUTH_CONTENT={} in the driver test factory, so the new OAuth read never reaches the host's real credential store during tests.

Why

Fixes #14983.

OpenCode 2.2.2 stores a signed-in Console account as an active OAuth credential with its workspace ID in credential metadata. T3 only decoded stored credentials of type key, so it discarded the valid Console login and retried the Go usage endpoint with a legacy key. The endpoint returned HTTP 401, and T3 displayed "OpenCode Go could not read usage."

This is a small, focused fix for an obvious compatibility bug. It restores the existing usage display without changing product behavior or adding a new workflow.

Reproduction on Linux with T3 Code nightly and OpenCode 2.2.2:

  1. Sign in to OpenCode Console through OAuth and select a workspace.
  2. Open T3 Code's provider status or usage view.
  3. Observe that OpenCode is authenticated and usable, but its Go usage probe reports probeFailed.
  4. Send the same OAuth access token with the stored workspace ID to the Go usage endpoint. The endpoint returns HTTP 200 with rolling, weekly, and monthly windows.

How I verified it

  • Added the OAuth and workspace-header case to the existing OpenCode status test. The focused test failed before the implementation because the header was absent, then passed after the fix.
  • The fingerprint expectations in that test now require one workspace fingerprint for both a Console key and an OAuth token. They fail on the first commit and pass on the second.
  • vp test run packages/provider-opencode/src/server/status.test.ts passed all 35 tests after rebasing on current main.
  • vp run check:changed passed formatting, lint, both knip checks, type checking for 10 affected packages, and 36 tests across two files.
  • Running the patched readOpenCodeGoUsageLimits against a real OpenCode 2.2.2 Console login returned the Session, Weekly, and Monthly windows with no unavailable reason.
  • A sanitized live request on Linux with an active OpenCode Console OAuth credential and its workspace header returned HTTP 200 with monthly, rolling, and weekly usage windows.
  • After the rebase onto current main, pnpm --filter @t3tools/provider-opencode test passed all 170 tests.
  • I did not run the full repository test suites or build. CI owns those checks.

State and next step

The focused fix and regression coverage are committed. CI and maintainer review are next. The live T3 service was not rebuilt or restarted.

Follow-ups

None.

Model and harness: GPT-5.6 Sol, Codex harness in T3 Code (first commit). Claude Opus 5.5, Claude Code harness in T3 Code (fingerprint fix). Rebase onto current main and driver-test isolation (third commit) by @goncalompontes, from #33287.

Walkthrough

The usage-limit lookup now reads stored Console key and OAuth credentials. It sends an associated workspace ID with requests, fingerprints OAuth credentials by workspace, and retries another credential after HTTP 401 or 403.

Changes: Console credential usage

Layer / File(s) Summary
Resolve stored credentials
packages/provider-opencode/src/server/usageLimits.ts, packages/provider-opencode/src/server/status.test.ts
The credential reader accepts stored key and OAuth records, extracts tokens and optional workspace IDs, and fingerprints OAuth credentials by workspace when available. Tests cover Console credential fixtures and fingerprint expectations.
Select credentials and send usage requests
packages/provider-opencode/src/server/usageLimits.ts, packages/provider-opencode/src/server/status.test.ts, packages/provider-opencode/src/server/driver.test.ts
The lookup orders and deduplicates credentials, sends the workspace header when available, and retries another credential only after HTTP 401 or 403. Tests check request headers and set explicit auth content in the test helper.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Medium

Possibly related issues

  • pingdotgg/t3code#31040 — The issue reports duplicate accounts when fingerprints depend on API keys. This change uses workspace-based fingerprints for OAuth credentials with a workspace ID, but it does not change the reported case involving multiple API keys.

Suggested reviewers: juliusmarminge, maria-rcks

Merge Risk: Low · previous review 0fd1b

The change adds OpenCode Console login support for usage limits. Limit accounts could be shown twice, or merged incorrectly for Go Teams members, in edge cases involving different credential forms. These cases are bounded and cosmetic to the limits display, so owners should be aware of them but the change is mergeable.

Explanation

The title "fix(opencode): read usage from Console OAuth logins" follows conventional commit format and names the main change. The changeset adds reading of active OpenCode Console OAuth credentials for Go usage limits, sends the workspace ID in a header, and fingerprints by workspace. The title matches the primary change and the linked objectives.

Full details: Description check

Explanation

The description follows the template's main sections. It has What changed, Why, and How I verified it, which cover the template's Problem and Change content. The Why section states the problem, the expected behavior, and reproduction steps. The Scope section is not labeled, but the description links issue #14983 and explains it is a small compatibility fix for an obvious bug. The Verification section lists focused tests, the repo checks it ran, and what it did not run. The description states that the full repository test suites and build were not run. The description also gives model and harness attribution, as the template asks. The template's section headings Problem, Change, Scope, and Verification are not used verbatim, but the required information is present.

Full details: Linked Issues check

Explanation

Issue #14983 is the only directly linked issue, and it is open. Its coding requirement is that Usage → Limits reports OpenCode Go session, weekly, and monthly windows for an OpenCode 2 Console login. That login has no opencode-go entry in auth.json and no OPENCODE_API_KEY. The issue does not require a specific mechanism. The current head changes readStoredCredential in usageLimits.ts to decode stored oauth credentials with optional orgID metadata. It returns the trimmed access token and workspace ID. Requests include x-opencode-org-id when a workspace ID is available. The legacy opencode-go key fallback remains after a 401 or 403. status.test.ts covers the OAuth and workspace-header case. The fingerprint change gives one workspace fingerprint for OAuth tokens, so rotating tokens do not split one workspace into several accounts. The issue's direction question is answered by the chosen mechanism, which is reading the OpenCode 2 credential store and the Console Go status endpoint. This verdict relies on the whole-PR summary and the reported test results. Source hunks were not read directly in this pass.

Full details: Out of Scope Changes check

Explanation

All changes connect to #14983. (1) usageLimits.ts: reads Console OAuth credentials, sends the workspace header, keeps the legacy fallback, deduplicates by token, and fingerprints OAuth credentials by workspace. These changes support the Console OAuth read. (2) status.test.ts: tests the OAuth, workspace-header, and fingerprint behavior. It also tests inline Console API keys, which keep their own fingerprint. (3) driver.test.ts: sets OPENCODE_AUTH_CONTENT to an empty value in the test factory. This isolates the new credential read from host credentials, so it is supporting test change. The summary shows no unrelated product change. Rebased commits from #33287 only add the isolation change and do not add unrelated work. This verdict relies on the whole-PR summary and was not checked against source hunks.

Key Console fingerprints by member, not only workspace.

Go Teams usage is tracked per workspace member. Two OAuth credentials in the same workspace can therefore return different limits. The OpenCode status has no email identity, so collectLimitAccounts falls back to credentialFingerprint; the current workspace-only fingerprint makes those accounts share a key, and the merge keeps only the fresher limits. Use a stable member identity in the fingerprint.

Preserve grouping when the same key lacks workspace metadata.

A Console key with a workspace ID now hashes differently from the same key supplied through OPENCODE_API_KEY or auth.json. Both requests can read the same Go allowance, but packages/shared/src/usageLimits.ts treats the results as separate accounts when no email is available. This duplicates the account and can distort pooled limits.

Preserve a token-based alias alongside the workspace identity so consumers can recognize both forms. (raw.githubusercontent.com)

Rebased this onto current main and opened #33287 so the fix is mergeable again. Both original commits are preserved with your authorship; the only added change is a driver-test isolation fix (OPENCODE_AUTH_CONTENT={}) so the new OAuth read does not touch the host credential store during tests. Verification and conflict-resolution details are in #33287. If you would rather keep this PR as the canonical one, the branch can be cherry-picked from https://github.com/goncalompontes/t3code/tree/fix/opencode-oauth-usage.

@Fushi500 the rebased commits are ready on goncalompontes:fix/opencode-oauth-usage (3 commits; focused package tests and check:changed pass). If you're still able to update this branch, a fast-forward/cherry-pick from that ref would put this PR back in a mergeable state. I can also push directly if you add me as a collaborator. Otherwise #33287 is the fallback mergeable copy, and I'm happy to close it if this one becomes canonical again.

When the selected Console credential and auth.json held the same token,
deduplication kept the auth.json entry and dropped the workspace header
and workspace fingerprint. The first source of a token now wins.

AI-assisted; verified with the tests and tools listed above.
Only OAuth tokens rotate, so only Console OAuth logins are fingerprinted
by workspace. A Console API key now fingerprints the same as that key
supplied inline, and one allowance shows as one account.

The automated pipeline stopped on this pull request and will not merge it:

the fix is written and reviewed, but proving it needs something no worker has:

  • Permanent blocker: a real OpenCode Console OAuth login to a workspace with an active Go subscription is required; this VM has no Console/Go credentials. Hub-backed OpenCode access does not supply that subscription session.
  • Base omission or probe failure and head Session, Weekly, and Monthly limits remain unverified. Both verdict flags are false because neither behavior was observed.

It stays open for a person to finish or close.
