Problem

With a Claude Code login used through OpenCode 2's built-in claude-agent provider, a spent Claude plan ends the run with session.execution.failed and { type: "provider.unknown", message: "You've hit your weekly limit · resets 9pm (Europe/Paris) Resets at 2026-11-02T20:00:00.000Z." }, with no status and no body. That payload is the reporter's live capture. The OpenCode adapter treats only provider.quota (when it isn't a 402) and provider.rate-limit as usage limits, so this failure became a plain provider error with no resetAt. As a result, Snooze until reset, Resume at reset and auto-resume never turned on.

Change

In packages/provider-opencode/src/server/v2/adapter.ts, a failure whose message starts with Claude's own You've hit your … limit wording is now classified as usage_limit. resetAt comes only from an explicit Resets at <ISO> tail. When there is no tail, no reset is guessed. makeProviderFailure already drops a timestamp it can't parse. Every other failure keeps its current classification: generic provider.unknown errors and 402 balance failures stay provider_error.

Scope and approval

Fixes pingdotgg/t3code#29289

Triaged via the automated issue flow.

Verification

Red test first, using the reporter's exact payload: classifies a Claude weekly limit as a usage limit that resets at its reported time in apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts. Two rows were added to the existing classification table:
- A Claude limit without a timestamp becomes usage_limit with no resetAt.
- An unrelated provider.unknown failure that ends in Resets at <ISO> stays provider_error.

Runtime transcript of the adapter's session.execution.failed path, with the test file at this head:

Before (adapter at main 47f2c8d29e): 2 failed

1	FAIL OpenCode2 adapter > classifies a Claude weekly limit as a usage limit that resets at its reported time
2	AssertionError: expected { class: 'provider_error', …(3) } to deeply equal { class: 'usage_limit', …(4) }

7	- "resetAt": "2026-11-02T20:00:00.000Z",

After (this head): all 10 classification tests pass, including the 402 and the provider.quota/provider.rate-limit rows.

Both new regexes run in linear time with no nested quantifiers. On a 3000-token malformed input they took about 0.01–0.03 ms per call.
Not checked: a live OpenCode 2 claude-agent run with an exhausted Claude plan, because no such account is available. The fix only changes server-side classification. The existing usage-limit UI renders the result unchanged, so there are no before/after captures.

Approvability

Verdict: Approved at c75d167

Macroscope's review found this PR approvable — Claude usage-limit errors received through OpenCode now retain their reset time and use existing usage-limit handling. The change is limited to failure metadata, with timestamp validation and recovery controls unchanged.

Walkthrough

The adapter now classifies matching Claude limit messages as usage_limit and includes an explicit reset timestamp when present. Regression tests cover messages with and without timestamps and an unrelated message that mentions a reset time.

Changes: Claude usage-limit handling

Layer / File(s)	Summary
Parse Claude limit messages `packages/provider-opencode/src/server/v2/adapter.ts`	A helper matches Claude plan-limit messages and extracts an optional trailing `Resets at` timestamp.
Classify execution failures `packages/provider-opencode/src/server/v2/adapter.ts`, `apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts`	Execution failures matching Claude limit messages become `usage_limit` and include the parsed reset time, or `null` if none is present. Tests cover messages with and without timestamps and an unrelated reset-time message.

Some limit messages may lose their reset time or be classified incorrectly. The change is mergeable with awareness of these bounded cases.

Full details: Title check

Explanation

The title names the main change: Claude usage limits routed through OpenCode now keep their reset time. It follows the conventional commit format and matches the adapter change and the new test in the summary and objectives. It does not describe unrelated work.

Full details: Description check

Explanation

The description follows the template. It has Problem, Change, Scope and approval, and Verification sections. The Problem section gives the reporter's payload and the expected behavior. The Change section explains the classification rule and the resetAt rule. The Scope section links issue #29289 and says the fix came from the automated issue flow. The Verification section names the red-first test, gives the before and after results, lists the commands run, and states what was not checked. The description does not state a maintainer approval comment, which the template asks for. The template is also specific about this, so the author should link that comment or explain the exemption more fully. The description names the model and harness, as the template requests.

Full details: Linked Issues check

Explanation

Issue #29289 requires Claude claude-agent limit failures to become usage_limit, preserve an explicit reset, and avoid guessed resets. claudeUsageLimit matches the Claude limit wording and extracts only a trailing Resets at <ISO> value. The session.execution.failed path passes that value to makeProviderFailure, which omits invalid or absent timestamps. The regression tests cover the captured weekly-limit payload, no timestamp, and unrelated provider.unknown errors.

Full details: Out of Scope Changes check

Explanation

The changes stay within issue #29289. They add the adapter classification logic and focused regression tests. The existing provider.quota and provider.rate-limit behavior remains in place, and unrelated provider.unknown errors and HTTP 402 failures remain provider errors. No unrelated provider, settings, scheduler, plugin, or account-usage changes are present.

Preserve the 402 exclusion.

If a provider.quota 402 failure says, for example, “You've hit your credit limit”, this branch overrides the existing 402 check and classifies it as usage_limit. The failure is then shown as a usage limit rather than a provider error. Exclude 402 from the Claude branch and add a case to the existing table. (raw.githubusercontent.com)

Trim the message before classification.

If OpenCode includes leading whitespace, this match fails. The formatter trims that same message for display, but the failure remains provider_error and loses its reset time. Classify the trimmed message instead. (raw.githubusercontent.com)
