Problem

If you press Stop while a Claude tool is still running, such as a long foreground Bash command, the work log shows that tool as failed ("Failed to …"). The tool did not fail. You stopped it, so it should show as stopped, like the turn does.

When Claude Code is interrupted, it sends an error tool_result for each running tool (is_error: true, tool_result_meta.non_execution_kind: "user-rejected"), followed by a result with terminal_reason: "aborted_tools". ClaudeAdapterV2.settleToolCall maps every error result to failed and takes the tool out of the open set. Because of that, the turn finalizer, which marks still-open tools interrupted, never sees it. Clients show interrupted and cancelled as stopped, but they show failed as a red failure.

Change

When the turn has already been interrupted (its provider turn id is in interruptedTurns, which interruptTurn sets before it calls the SDK's interrupt), settleToolCall now records a tool error result as interrupted. The status is the same one endToolCalls already gives tools that are still open when an interrupted turn ends. It also matches the OpenCode fix in #29762.

Workflow members get the same treatment. When Stop cancels a workflow, the adapter settles member tools from each member's transcript, without a turn context. If the member was cancelled and the error line has Claude's denial marker (toolDenialKind, set to "user-rejected" in Claude's Stop reply), that tool is now recorded as interrupted. A genuine member tool failure that is first read after Stop has no denial marker, so it stays failed.

I used the interrupt flag rather than non_execution_kind: "user-rejected". That kind may also describe a real permission rejection, and the existing non-execution table test treats every kind other than cancelled as a failure.

Scope and approval

This is a very small, focused fix for an obvious bug, so there is no prior issue. The adapter already models "interrupted" for tools that are open when Stop ends a turn. This change only stops the CLI's own Stop reply from turning those tools into failures. It is about 16 non-test lines in ClaudeAdapterV2.ts.

Overlap search: I searched the local PR index and GitHub for Claude Stop/interrupt and tool status changes. The closest PRs are #21158 and #15868 (a steer cancelling or interrupting Claude tools) and #28356 and #27487 (subagent rows stuck on Running). None of them touch settleToolCall or how a tool's error is classified after Stop.

Verification

• Real CLI behavior: with Claude Agent SDK 0.3.276 and Claude Code 2.1.314 on Haiku, I ran ping -c 25 127.0.0.1 in Bash and called interrupt() after 4 s. The output was a tool_result with is_error: true and tool_result_meta: [{ non_execution_kind: "user-rejected" }], then [Request interrupted by user for tool use], then a result with subtype: "error_during_execution" and terminal_reason: "aborted_tools".
• I extended the existing test lets the native SDK acknowledge Stop before closing its own query in ClaudeAdapterV2.test.ts. A Bash tool is running, and the Stop acknowledgement sends the real-shaped error tool_result followed by the aborted_tools result. On main it fails with AssertionError: expected 'failed' to equal 'interrupted'.
• Workflow members: I added the test shows a workflow member's tool as stopped when Stop cancels the workflow. In it, a member's first tool fails for real, its second gets the Stop reply, and then the workflow is stopped. Without the member change it fails with - "command interrupted: Rejected" + "command failed: Rejected". The transcript shape comes from real local Claude Code transcripts, subagent sidechains included: the Stop reply is an error tool_result with toolUseResult: "User rejected tool use" and toolDenialKind: "user-rejected", and genuine tool failures have no toolDenialKind.
• With the fix, vp test run src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts passes 289/289, and ClaudeReplayFixtures.integration.test.ts passes 38/38.
• CI=true vp run check:changed passes: format, lint, knip, typecheck (3 packages), and tests (290).
• Not checked: a real client capture. The visible change is the existing "Stopped …" label in place of "Failed to …" for that row.

Reviewed with sol-loop: 1 round with GPT-6.1 Sol on high for the main change and 2 rounds for the workflow-member follow-up. Sol verdict: approved. Round 1 of the follow-up found that a genuine failure read late was being relabeled; the toolDenialKind check fixed it.

Walkthrough

ClaudeAdapterV2 now passes cancelled workflow-member state to tool settlement. Rejected tool results for stopped targets are marked interrupted; other error results remain failed. Tests cover graceful Stop and workflow-stop projection.

Changes: Claude tool interruption status

Layer / File(s)	Summary
Settle stopped tool calls apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts	Workflow-member projection sets a stopped flag when the member is cancelled. Tool settlement uses that flag for rejected tool results and marks them interrupted; other error results remain failed. Tests verify the status for graceful Stop and workflow stop, including preservation of a previously failed command.

Full details: Title check

Explanation

The title "fix(claude): tools running at Stop show as stopped, not failed" matches the main change. The adapter now records a tool error result as interrupted when the turn was interrupted, so a tool running at Stop shows as stopped rather than failed. The title is specific and follows the conventional commit style the template requests.

Full details: Description check

Explanation

The description follows the template well. It has Problem, Change, Scope and approval, and Verification sections. The Problem section gives the expected behavior and the mechanism. The Change section explains the interrupt-flag approach and the workflow-member handling. The Scope section argues why the fix qualifies as a small obvious bug fix without a prior issue, and it lists an overlap search. The Verification section gives specific tests, observed results, and items not checked. The description does not link a triaged issue or maintainer approval, which the template asks for unless the fix qualifies as a small obvious bug. The author argues that it does qualify. The Verification section also reports a count of 289/289 tests, while the PR objectives report 288/288. This is a minor inconsistency that the author should reconcile. The template's optional trailing note about the agent and model is present.

Verified in a real dev environment

Verified latest contributor head b6bcfae4d48b4fdfa653321a379ff3515d0460b6, including the workflow-member follow-up pushed during this pass. Used repository Playwright with /usr/bin/google-chrome on Linux, vp i, and real background dev servers run sequentially with isolated state. Created a real git project and provider turns through the web app. No mocks or seeded demo turns.

• Real Claude Sonnet 4.6 through the local Anthropic-compatible proxy, CLI 2.1.316 and SDK 0.3.276: foreground ping -c 120 127.0.0.1, then the composer's Stop. The UI showed Run interrupted / Stopped by user; the persisted Bash item was interrupted.
• Resumed that stopped thread. printf pr29801-latest-resume-ok completed. ls /tmp/pr29801-deliberately-missing-path remained failed, with exit code 2. Earlier Stop and follow-up results also survived a server restart.
• Real native Claude Workflow with one Sonnet 4.6 member: used the root waiting-task Stop control while the member's foreground ping ran. The member became cancelled, and its Bash item persisted as interrupted.
• Real Codex gpt-6.1-sol terminal command returned pr29801-latest-codex-ok on this head. The same client/provider path also completed on main.
• Blacksmith at this head: 289 Claude adapter tests and 38 Claude replay integration tests passed, including both Stop regressions. No source changes, commits, or pushes were needed.

Stop recording at the latest head:

Resume succeeds and actual command failure stays failed:

Workflow member after Stop:

Not verified

The original red-failure regression did not reproduce live on current github/main (61c3794c32). Baseline attempts with Claude CLI 2.1.316 and the report's 2.1.314 both persisted the stopped tool as interrupted. These runs verify expected live behavior, but do not establish a live failing-before/passing-after comparison.

The real workflow stop transcript lacked toolDenialKind, so it did not prove the newly added workflow denial-classification branch ran. That exact case, including preservation of a genuine earlier failure, passed the regression test. A genuine permission rejection, native desktop/iOS/Android clients, and relay/tunnel connections were not exercised. The proxy rejected Haiku's normalized alias, so Claude integration checks used Sonnet 4.6.

Baseline with the same ping prompt:

Runtime command transcript.
