Wires the external abort signal and per-request timeout into the completePrompt (non-streaming) and createMessage (streaming) paths of the Opencode Go provider. Stacks on the shared-util unit of this split (resolveModelWithAbort in utils/abort-signal.ts).

• completePrompt: forwards options?.abortSignal / options?.timeoutMs to all three wire formats (Anthropic /v1/messages, OpenAI chat.completions, and the Responses /v1/responses path); timeoutMs <= 0 omits the SDK timeout option (the SDK treats timeout: 0 as an immediate abort); aborted completions and SDK connection/timeout errors normalize to the provider AbortError.
• createMessage: bridges metadata?.abortSignal (Bedrock pattern: pre-aborted guard, { once: true } listener, detached on completion so a task-scoped signal does not accumulate listeners) into a per-request AbortController shared by all three streaming wire formats; model resolution runs inside the shared resolveModelWithAbort cancellation scope (pre-aborted fast-fail, mid-resolution race).
• Aborted/timeout requests normalize to the provider AbortError on all three wire formats, both pre-stream and mid-stream; non-abort failures keep the wrapped "Opencode Go completion error:" identity.

Tests:

• Ported the reference abort/timeout completePrompt pass-through tests (signal, timeoutMs incl. 0, and no-options backward compatibility) for all three wire formats, plus normalization/identity tests for aborted and timed-out completions.
• createMessage bridging tests: pre-aborted signal -> rejects with the standardized AbortError before any request work; abort mid-resolution -> settles on the standardized AbortError before the lookup is released; mid-stream abort on each wire format -> standardized AbortError; detach tests use the reference-identity pattern (the resolution race registers its own listener, so the bridge is the last "abort" registration).

Series and unit

Unit 2/3 of the #1295 split (content source: 62f596c5d); stacks on the shared-util unit.

Part of the abort-signal series (round 1). Builds on #674, #901, #1008. Addresses #404.

Review response (maintainer review of #1295)

• The Responses completePrompt catch now has the same abort normalization as the OpenAI path (isRequestAborted(error, options?.abortSignal) || error instanceof APIConnectionTimeoutError -> provider AbortError), pinned by "preserves abort identity on the Responses completion path" and "surfaces Responses request timeouts as an AbortError in completePrompt".
• The Responses streaming branch now has a mid-stream catch mirroring the anthropic branch, and streamResponsesMessage has the same pre-stream guard as streamAnthropicMessage (aborted/timeout requests normalize instead of wrapping).
• The model-resolution guard/race/normalization lives once in the shared util (resolveModelWithAbort, unit 1/3); opencode-go's pre-aborted fast-fail happens before any catalog/SDK work (pinned: catalog and SDK both uncalled).
• The createMessage catch uses the wider isRequestAborted condition (aborted signal, DOM AbortError, SDK APIUserAbortError, exact "Request was aborted." message; name/message checks require a real Error instance).
• The detach test asserts reference identity on the last "abort" registration, because the resolution race registers its own listener on the same external signal.

Evidence

• vitest: 123/123 passing in the opencode-go suite (154 changed executable lines, all covered)
• Local Stryker mutation gate (unit delta vs own base): 209 valid mutants (≤400), 202 killed, 7 directive-ignored (the per-request bridge's unreachable pre-aborted branch plus two inner-guard equivalence proofs — see the equivalence note below), 0 Survived / 0 NoCoverage / 0 Timeout

CodeRabbit fix (post-review)

CodeRabbit's finding on this PR (cleanup terminal paths): the OpenAI branch converted messages and built the request body before its try/finally, so a conversion failure (e.g. an unstringifiable tool input) left the bridged abort listener attached. Fixed:

• the conversion and request construction now run inside the same cleanup scope as the Anthropic and Responses branches (listener detaches on conversion failure too); abort normalization for successful/aborted requests is unchanged,
• a kill test pins the new terminal path: an unstringifiable tool input propagates unchanged and detaches the bridge listener by reference,
• the re-indentation made the gate instrument pre-existing request-construction lines for the first time; their previously unobservable mutants are now kill-tested (R1 tool-result merge shape for preserveReasoning models and the plain shape for non-preserveReasoning models, the includeMaxTokens on/off branches with a ceiling-bounded model, and the parallel_tool_calls default/explicit-false).

Equivalence note (directive proofs)

Two of the directives cover provably-equivalent inner-guard mutants. createMessage wraps the yield* of each streaming generator in an outer catch that applies the identical isRequestAborted check to the same per-request controller signal and re-throws the standardized AbortError. Therefore:

• the inner pre-stream guard's condition (Responses path): a mutation of the condition only changes behavior for errors the outer predicate would not catch — but every abort-flavored error that reaches the inner layer implies the controller signal is already aborted (the SDK rejects because the bridged signal aborted), so the outer predicate fires identically and re-standardizes;
• the inner guard's provider-name literal: the inner throw's output is itself re-caught by the outer layer, whose predicate matches on the standardized error's own name === "AbortError", so the outer re-standardizes with the correct provider name and the inner literal is unobservable.

The inner layer's unique, kill-tested behavior is the non-abort "Opencode Go completion error:" wrap.

---

Out-of-scope sanitize-surrogates removal (pre-merge Out-of-Scope check, error row): the cycle-detection change to sanitizeSurrogatesDeep and its spec rode in on an earlier shapes/upstream-main merge (c94e614) and are not part of this unit's declared scope (Opencode Go abort/timeout: opencode-go.ts + its spec). Restored both files to main's state (e594ff4); the listener-detach regression test now fails the message conversion with a throwing value getter — the "unstringifiable tool input" scenario it documents — instead of a self-referential input, removing the only dependency on the out-of-scope change. PR diff is exactly the two unit files.

Review follow-ups

• completePrompt model resolution is inside the cancellation scope. It now resolves through resolveModelWithAbort, the same helper createMessage uses, so a pre-aborted signal rejects before the /models lookup, an abort during the lookup settles on the provider AbortError (not the raw lookup failure), and timeoutMs bounds that phase. Specs park getModels on a gate to prove the abort settles before the lookup releases, and assert the pre-aborted case never touches the catalog.
• One abort predicate across the three completePrompt branches. The Anthropic and OpenAI chat branches now use isRequestAborted(error, options?.abortSignal) plus the SDK timeout class, matching the Responses branch, and the then-unused APIUserAbortError imports were removed. Behavior is unchanged; the name-based abort, timeout and mid-flight cancellation tests stay green.

📝 Summary

Summary by CodeRabbit

• Bug Fixes
  • OpenCode Go requests now honor cancellation during chat, message, response, and streaming interactions, including while resolving models or processing streams.
  • Caller cancellations and recognized provider abort or timeout errors are consistently reported as cancellations; other provider errors retain their existing handling.
  • Completion deadlines now cover model resolution and can settle requests even when the provider remains pending.
  • Non-positive timeout values are omitted from requests, and cancellation handling remains consistent when requests or streams fail.

Opencode Go streaming and completion requests now forward abort signals and normalize recognized cancellation and timeout errors. Requests omit non-positive timeouts. Tests cover request options, message conversion, stream output, cancellation, and listener cleanup.

Changes: Opencode Go cancellation handling

Layer / File(s)	Summary
Streaming cancellation and stream handling src/api/providers/opencode-go.ts, src/api/providers/__tests__/opencode-go.spec.ts	Streaming requests resolve models under the caller’s abort signal and pass bridged signals to provider SDKs. Recognized cancellations return a standardized AbortError. Tests cover cancellation, listener cleanup, stream frames, message conversion, token limits, and tool-call settings.
Completion cancellation and timeout options src/api/providers/opencode-go.ts, src/api/providers/__tests__/opencode-go.spec.ts	Anthropic, Responses, and OpenAI completion requests use the caller’s signal and usable timeouts. Recognized abort and timeout errors become standardized AbortErrors. Tests cover request options, model resolution, and timeout handling.

Merge Risk: Low · up to 906ce

Canceling a context-recovery request may be delayed during provider retries. Merge with awareness of this limited risk.

Security architecture risk: Low · up to 3eb63

The change improves cancellation handling and rejects cyclic inputs. Risk is low, but termination of actual network work is not fully established. Non-streaming requests also retain an existing metadata-loading stage that cancellation and request timeouts do not bound.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — Cancellation state is isolated per streaming invocation. Shared cycle-validation behavior can affect existing provider consumers of tool schemas and nested tool data, but the reviewed changes do not add callers or expand credential authority. Complete transitive consumer coverage is not established.

Trust Boundaries and Controls

• observed — MCP tool schemas already pass through the shared sanitizer at outbound request construction. The added cycle guard rejects circular in-memory structures at that existing boundary; it is an input-validity control, not an authentication or tool-execution authorization control.

Resilience and Maintainability Implications

• inferred — Signal propagation and cleanup support request-level failure containment, but mocked SDK behavior does not prove termination of production HTTP requests or remote generation. An already-aborted signal reaching an SDK after completion model resolution is therefore not evidence that no network work can occur.

Full details: Security Boundaries

Explanation

No changed path meets a security-boundary failure condition. The runtime diff in src/api/providers/opencode-go.ts adds abort-signal bridging, timeout validation, request cancellation, and error normalization. It does not add secret or PII handling, dynamic code execution, or approval/allowlist bypasses. Prompt, message, tool, and session-header forwarding existed before these changes. The test-only changes add coverage and do not alter production behavior.

Full details: Persistence Integrity

Explanation

PASS. The pull request changes only src/api/providers/opencode-go.ts and its tests. The changed code resolves models and sends streaming or completion requests; it does not add or modify a persistence path, storage write, transaction, rollback, or persisted default propagation. The x-opencode-session header and Responses store: false setting are request behavior, not persistence operations.

Full details: Regression Evidence

Explanation

The standing regression remains unresolved. completePrompt now applies hasUsableTimeout and toSdkTimeoutMs to all three provider request-option paths (opencode-go.ts:873-875, 931-933, and 1014-1016). The provider tests cover only positive values, 0, and -1 for Anthropic, Responses, and Chat Completions. They do not capture those SDK calls for NaN, Infinity, fractional 12.5, or a value above MAX_TIMEOUT_MS. The shared helper tests cover the helper itself, but they do not prove that each provider path omits or converts the request option.

Resolution

Add focused completePrompt request-option tests for Anthropic, OpenAI Chat Completions, and Responses. Capture each SDK call's options and verify that NaN and Infinity omit timeout, 12.5 forwards timeout: 13, and a value above MAX_TIMEOUT_MS forwards timeout: MAX_TIMEOUT_MS.

Full details: Lifecycle Resource Cleanup

Explanation

Unresolved lifecycle leak during model discovery. The changed createMessage and completePrompt paths race resolveModelWithAbort at opencode-go.ts:248 and :860, but resolveModel() at :182 calls fetchModel() without a signal. RouterProvider.fetchModel() passes no signal to getModels() or refreshModels() (router-provider.ts:83-94). Therefore, when the uncached /models request is pending and the caller aborts, only the outer resolution promise settles. The provider request and model-cache single-flight continue until completion or the 15-second bound, and a late result can still populate the cache. This is a changed cancellation path that keeps provider work alive after cancellation.

Resolution

Thread the merged cancellation signal through resolveModelWithAbort, resolveModel, and RouterProvider.fetchModel into getModels and refreshModels. Ensure the model-cache single-flight releases or aborts its underlying provider fetch when its last waiter cancels while preserving active sibling waiters. Add a test that aborts during uncached Opencode Go /models discovery and verifies provider-fetch cancellation or flight release.

🟡 Minor · completePrompt ignores options.abortSignal during model resolution.

src/api/providers/opencode-go.ts:805
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

completePrompt ignores options.abortSignal during model resolution.

Line 805 calls this.resolveModel() without the caller signal. Two gaps follow. A caller that aborts before or during the catalog fetch does not fail fast; the request still starts after resolution completes. An abort-flavored catalog failure propagates raw, because the per-format catches only wrap the SDK call. createMessage already uses resolveModelWithAbort for the same purpose at line 212.

🛠️ Proposed fix

-		const { id: modelId, format, temperature, reasoningEffort, maxTokens } = await this.resolveModel()
+		const { id: modelId, format, temperature, reasoningEffort, maxTokens } = await resolveModelWithAbort(
+			() => this.resolveModel(),

All three review threads addressed

• Model-resolution timeout — completePrompt now passes mergeAbortSignalAndTimeout(options?.abortSignal, options?.timeoutMs) to resolveModelWithAbort, so the caller's per-request timeout really bounds the /models resolution phase (matching the comment/PR body); the SDK request keeps its validated timeout option.
• Shared abort bridge — createMessage replaces the inline controller/listener/pre-aborted/removal block with bridgeExternalAbortSignal(metadata?.abortSignal) and calls its dispose() in the three format branches' finally blocks. The streaming helpers' signal parameter is now optional, and a never-aborting fallback signal preserves the previous always-signal behaviour when the caller supplies none.
• Abort test exercises the catch — the Anthropic and OpenAI completePrompt abort-identity tests no longer pre-abort before the call (which only exercised resolveModelWithAbort's guard): the mock now starts the request, aborts the caller signal mid-request, and rejects with a plain Error, so the catch's merged-signal classification is what produces the AbortError.

Follow-up thread addressed

The merged resolutionAbortSignal (caller signal + per-request timeout) is now forwarded to the Anthropic, Responses and Chat Completions SDK request options, so model resolution and the completion request share the same deadline instead of the SDK request seeing only the caller signal. The tests now assert the composite signal is forwarded (and that the SDK timeout option is still set), including the timeout-only case.

Both follow-up threads addressed

• Shared deadline regression coverage — added a per-format it.each (Anthropic / Responses / OpenAI): model resolution is delayed past timeoutMs and the call rejects AbortError without starting the completion request, proving resolution is bounded by the same deadline. A further regression test keeps the SDK request pending (simulating a retry backoff longer than timeoutMs) and asserts the call still rejects at the deadline with the request signal aborted.
• Retry delays cannot outlast the deadline — the Responses and Chat Completions SDK promises are now raced with the merged resolutionAbortSignal via rejectOnAbort, so an SDK retry delay cannot keep completePrompt waiting past the caller's timeout. completePrompt keeps passing the merged signal to both request formats.

Local: opencode-go.spec.ts 182 passed; tsc clean.

Follow-up thread addressed

The pending-request deadline regression test is now parameterized over the two request branches: Chat Completions (mockCreate, GLM model) and Responses (mockResponsesCreate, gpt-5.6-luna). For each format the SDK promise never settles (retry backoff longer than timeoutMs); the test asserts an AbortError, bounded elapsed time, and that the captured request signal is aborted at the shared deadline.

Local: opencode-go.spec.ts 183 passed.

Follow-up thread addressed

• The Anthropic messages.create promise is now also raced with rejectOnAbort(resolutionAbortSignal) (same as Responses / Chat Completions), so a retry backoff longer than timeoutMs cannot keep completePrompt waiting past the caller's budget. Request parameters/options are unchanged.
• The parameterized pending-request deadline test now includes the Anthropic format (mockAnthropicCreate + qwen3.7-max) alongside Chat Completions and Responses.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Race the Chat Completions request with abort.

The PR adds requestSignal to this call, but the OpenAI SDK does not interrupt retry backoff when that signal aborts. If cancellation occurs during retry backoff, createMessage can remain pending until the backoff ends. The default maxRetries is 2, but an accepted Retry-After value can delay each retry for almost 60 seconds. Race this promise with rejectOnAbort(..., requestSignal, "Opencode Go"), as completePrompt already does.

Suggested fix

-			const completion = await this.client.chat.completions.create(body, {
-				signal: requestSignal,
-				headers: { "x-opencode-session": metadata?.taskId ?? this.sessionId },
-			})
+			const completion = await rejectOnAbort(
+				this.client.chat.completions.create(body, {
+					signal: requestSignal,
+					headers: { "x-opencode-session": metadata?.taskId ?? this.sessionId },
+				}),

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Race the Anthropic streaming request with abortSignal.

The base did not forward a signal. This PR adds the signal, but the Anthropic SDK retry path does not interrupt its sleep when the signal aborts. A caller cancellation can therefore leave the direct await pending until the retry delay ends. Wrap the SDK promise with the existing rejectOnAbort helper.

Suggested fix

 	private async *streamAnthropicMessage(
...
-		abortSignal: AbortSignal | undefined,
+		abortSignal: AbortSignal,
...
-			stream = await this.anthropicClient.messages.create(requestParams, {
-				signal: abortSignal,
-				headers: { "x-opencode-session": metadata?.taskId ?? this.sessionId },
-			})
+			stream = await rejectOnAbort(
+				this.anthropicClient.messages.create(requestParams, {
+					signal: abortSignal,
+					headers: { "x-opencode-session": metadata?.taskId ?? this.sessionId },
+				}),
+				abortSignal,
+				"Opencode Go",
