In packages/provider-opencode/src/server/v2/adapter.ts submit, /goal clear and /goal pause are forwarded to OpenCode's goal session command. With no goal set, OpenCode answers HTTP 500, which the client decodes as a typed CommandExecutionError ("No goal is set."). submit did not catch it, so startTurn wrapped it as ProviderAdapterTurnStartError and the thread showed only the generic failure. Reproduced with the repro branch's test, which failed with exactly that error. The fix applies to the pause and clear goal commands only: a CommandExecutionError whose message is exactly "No goal is set." is treated as a no-op, and the turn finishes as completed through the existing finishControl path. That matches the Codex adapter, which completes the same command as a no-op. Every other error, and every other forwarded command, behaves as before. If OpenCode rewords the message, behaviour falls back to today's failure. No regex or parser was added; the match is one exact string comparison.

Fixes #35872

Reproduction on main

On origin/main 95cb068: installed @opencode/cli@2.2.7 (the reporter's version) and put it first on PATH, started vp run dev with T3CODE_DEV_SEED=0 (fresh database), enabled the opencode provider instance in the worktree's own settings.json, added an empty git repo as a project with t3 project add, then ran t3 thread start --provider opencode --model anthropic/claude-haiku-4-5 --wait --json <project> "/goal clear". The run ended failed with "The provider could not start this turn. Retry the turn; if it keeps failing, check the provider setup and server logs." The server trace showed the adapter forwarding the message as POST /api/session/<id>/command (name goal, text clear), opencode answering HTTP 500 with CommandExecutionError: No goal is set., and OpenCode2Adapter.startTurn failing with ProviderAdapterTurnStartError. That cause appears only in the trace, not in the failure the thread stores. A unit test with the same replayed 500 fails on main the same way.

Evidence

Send /goal clear to a fresh OpenCode 2.2.7 thread using anthropic/claude-haiku-4-5, then repeat through the web composer. Both sides use fresh databases, the same empty repository, Chromium at 1440×900, and light theme.

Before	After
95cb068c10	04cb3646bb
Before recording	After recording

Base stores failed with the generic provider error. Head stores completed, with no active run or assistant reply: a harmless no-op.

Reproduction script · Sanitized runtime results

Not shown:

• The fix also handles pausing a missing goal; this proof exercised only /goal clear.

Tests

vp test run src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts -t goal (from apps/server) on the repro branch before the fix: the repro test failed with ProviderAdapterTurnStartError caused by CommandExecutionError 'No goal is set.'. After the fix: vp test run src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts, 170/170 passed. vp run check:changed: format, lint, knip, graphql, typecheck (10 packages) and tests (2 files, 172 tests) all passed.

Not in this change

• Codex replies with a visible 'No goal is set.' message for a no-op clear or pause; the OpenCode adapter now completes silently, because posting a synthetic assistant message would need new adapter machinery.
• Other OpenCode command failures still become a generic ProviderAdapterTurnStartError whose stored failure leaves out the provider's message; surfacing the cause in the stored failure is a separate change.

Approvability

Verdict: Approved at 04cb364

Macroscope's review found this PR approvable — OpenCode goal pause/clear commands now complete as no-ops when no goal exists. Handling is restricted to that exact provider error, leaving other commands and failures unchanged.

Walkthrough

The OpenCode adapter now treats “No goal is set.” as a no-op for /goal pause and /goal clear, then finishes the turn. A regression test verifies that /goal clear completes the turn when OpenCode reports this error.

Changes: Goal command completion

Layer / File(s)	Summary
Goal command completion handling packages/provider-opencode/src/server/v2/adapter.ts, apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts	For /goal pause and /goal clear, the adapter ignores the exact “No goal is set.” command error and finishes the turn. Other recognized commands return the command effect as void without explicitly finishing the turn. The regression test checks that /goal clear completes the turn when the error occurs.

Full details: Title check

Explanation

The title names the fix and the affected area: OpenCode /goal clear with no goal set now finishes as a no-op. It matches the main change in adapter.ts and the regression test. It is a conventional commit title in plain language, as the template asks.

Full details: Linked Issues check

Explanation

[#35872] The issue offers two options: (a) a no-op completion for /goal clear with no goal set, matching Codex, or (b) a failure message that keeps the cause. The PR takes option (a) in part. In packages/provider-opencode/src/server/v2/adapter.ts submit, /goal pause and /goal clear now catch a CommandExecutionError whose message is exactly "No goal is set." and continue to finishControl. The turn completes and no longer fails with ProviderAdapterTurnStartError. Other errors still propagate. The test added in apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts covers the 500 path. The PR does not post the visible "No goal is set." text that option (a) names. The PR states this choice and gives a reason. The author reports the repro test failed before the fix and the test file passed 170/170 after it. The real-app before/after evidence is still marked as pending. That evidence is not a coding requirement. Stack evidence is unavailable, so no stack objectives apply beyond this PR.

Full details: Out of Scope Changes check

Explanation

The adapter diff against the merge base changes only the goal-command branch of submit. The pause/clear branch now catches the exact "No goal is set." error and then calls finishControl. This is the requested fix. The other forwarded commands now run client.session.command(...).pipe(Effect.asVoid). That path still waits for the command and returns, as before, so its behavior is unchanged. The regression test in OpenCode2AdapterV2.test.ts supports the fix. No unrelated files appear in the reviewed changes. The PR does not change error surfacing for other failures; the PR marks that as outside this change.

Full details: Description check

Explanation

The description covers the problem (/goal clear and /goal pause return HTTP 500 with CommandExecutionError 'No goal is set.' and the thread shows a generic failure), the change (exact-message no-op handling routed through finishControl), reproduction steps on main, before/after evidence, test commands and results, and the authors of the work. It follows the template's Problem, Change, Verification sections. The Scope section is only partly addressed: it links issue #35872 (#35872) as the bug, which satisfies the requirement to link the issue. The description does not explicitly say why the change needs no issue, but a linked issue exists, so that is not required. Minor gaps: the Verification section mentions a 'Not shown' item and the reproduction was on a separate branch. These are non-critical. Overall the description is mostly complete.
