fix(web): keep thoughts and failed tool calls in one activity row by maria-rcks · Pull Request #12270 · pingdotgg/t3code

maria-rcks · 2026-09-17T16:39:37Z

Failed tool calls were excluded from the activity group, so every failure cut the row and left each thought standing alone as its own "Thought" line between tool summaries. The same turn now folds into one changing row.

isActivityEntry no longer rejects failed tool rows, matching how plain tool groups already absorb them. A group whose latest tool is not running or cleanly completed (failed, declined, stopped) settles instead of taking the live row, the same rule the live tool row already uses, so the "Thinking" placeholder still follows it, and the group row carries the failed icon like a tool toggle.
A collapsed "Thought" or live "Thinking" row shows the first line of the latest trace beside the label in the foreground color, so the changing row carries the thought without expanding.
Inside an expanded group each thought renders as brain icon, "Thought", then the reasoning text in the foreground color, capped at the same height as the standalone trace. A thought-only group shows its text directly instead of a nested toggle. The standalone reasoning row keeps its toggle, renders foreground text, and loses the multi-message and streaming branches that only the removed nested path could reach.
A trailing failed tool inside a live turn is now visible inside the collapsed group instead of being hidden until the turn settles.
Mobile had the same rule in its activity run grouping (activityRunTurnId), so failed calls now stay inside the run there too and the run summary carries the failure mark.

Verified on a copy of a real Claude thread with several failed preview_open and preview_status calls. MessagesTimeline.logic.test.ts (120 tests), threadActivity.test.ts (108 tests), web and mobile typecheck, and lint pass on Blacksmith. The live "Thinking" shimmer with a preview beside it is unverified: the sweep animates only the label word, but it still travels the full row width, and I did not record a streaming turn. Mobile evidence is unverified; the mobile change is the same one-line filter with its existing test updated.

Approvability

Verdict: Approved at 1989201

Macroscope's review found this PR approvable — This is a focused, test-backed web and mobile chat bug fix that keeps failed tool calls and thoughts together without changing schemas, defaults, or external workflows. The remaining concern is a localized composability preference, not a concrete runtime or correctness risk.

📝 Walkthrough

Walkthrough

The timeline keeps failed tools in activity groups, prevents failed latest tools from becoming active rows, exposes failure status, and renders reasoning traces inline. Tests cover live and settled projections for failed and declined tools.

Changes

Activity group behavior

Layer / File(s)	Summary
Activity grouping projection `apps/web/src/components/chat/MessagesTimeline.logic.ts`, `apps/mobile/src/lib/threadActivity.ts`, `apps/web/src/components/chat/MessagesTimeline.logic.test.ts`, `apps/mobile/src/lib/threadActivity.test.ts`	Failed tools remain in activity groups. Failed latest tools do not mark the group active. Web and mobile tests cover the updated grouping behavior.
Activity group rendering `apps/web/src/components/chat/MessagesTimeline.tsx`	Activity groups expose failure status through accessibility text and `LiveActivityRow`. Expanded reasoning uses inline `ReasoningTraceBlock` rendering. Standalone reasoning rows render one static thought message without the previous muted padded container.

Merges `pingdotgg/t3code` `6d1d549441..9946541` (50 commits) into the fork. Landed 304 files against 303 in the upstream range — the extra one is `docs/fork/inventory.json`. Fork delta is 777 files, unchanged from the last merge. Everything upstream changed landed. Six conflicts, each resolved with the verdict `preflight.mjs` printed; five were a single hunk. Details and reasoning are in [the merge tracker](docs/fork/upstream-merge-log.md). The two worth reading here: - **`ChatView.tsx`** — pingdotgg#12306 added `activeWorktreePath !== null` to the "Revert files too" button, on the line the fork gates with `FEATURES.checkpointFileRestore`. Kept both as a conjunction: upstream's condition is about a shared workspace, the fork's is about what Moatless serves, and they answer different questions. - **`FilePreviewPanel.tsx`** (the one `decide`) — pingdotgg#10909 restructured the file read so a folder is knowable as a folder, adding `isDirectory` / `previewPath`. Took that whole and re-stated the fork's `onRetargetFile` effect on top. `apps/web/src/routeTree.gen.ts` was regenerated rather than hand-resolved. One judgement call: pingdotgg#11598's new `/settings/storage` page is deliberately **not** given a `FEATURES` gate. It self-gates on two new capability booleans Moatless does not report and renders an explanatory notice, so a fork flag would duplicate a decision the wire already makes — and would have to be deleted again the day the capability is reported. ## Usable as-is - Diff files open from a right-click context menu (pingdotgg#11842). - Sidebar filtering from the thread menu (pingdotgg#8719). - Command palette matches thread IDs (pingdotgg#11185). - Mobile settings are easier to navigate and scope (pingdotgg#12272); favorites in the mobile model picker (pingdotgg#12231). - Thoughts collapse within tool groups (pingdotgg#12302); thoughts and failed tool calls stay in one activity row (pingdotgg#12270). - Folder links from chat open the file tree instead of a broken preview (pingdotgg#10909). - Chat no longer jumps when the scroll-to-end pill mounts (pingdotgg#12317); numbered jumps no longer steal browser tabs (pingdotgg#12315); composer banners stay compact (pingdotgg#12166). - A large batch of shared-component refactors across web and mobile (pingdotgg#12353–pingdotgg#12371). ## Unsupported in Moatless / needs implementation - **Pull request files marked as viewed** (pingdotgg#7721) — adds `pullRequests.filesViewed` and `pullRequests.setFilesViewed`, which record which files a reviewer has checked off, persisted server-side. Both declare `PullRequestRpcError` and so arrived already refusing; `unsupported-methods.mjs` reported ADD 0 / DROP 0 as a result. Closes with the rest of the `pullRequests.*` group, not separately. - **Multi-model threads in separate worktrees** (pingdotgg#12179) — one prompt starts a thread per selected model, each in its own worktree. The model picker is the same `worktree` send-mode control `FEATURES.worktreeSelection` already gates, so the fan-out is simply not offered. The same commit adds a `requiredWorktreeBootstrap` capability the backend does not report. - **Automatic storage cleanup settings** (pingdotgg#11598) — the `/settings/storage` page, gated by the backend's absent `storageCleanup` and `projectWorktreeCleanup` capabilities. Needs the sweeper below before the page means anything. - **Command palette entries for the pull requests and usage pages** (pingdotgg#12211) — the PR half is covered by `FEATURES.pullRequestSurface`. ## Backend behavior to consider reproducing in Moatless Eight items, recorded in full in [the gaps register](docs/fork/gaps.md) under _Runtime fixes upstream made to its own server_. Five are on the checkpoint and usage paths the previous merge already opened: - **Reject a file rewind on a shared or nested-owner cwd** (pingdotgg#12306, `CheckpointReactor.ts`) — a checkpoint holds the whole checkout, so restoring one erases a sibling's uncommitted work. Moatless isolates by sandbox, but a workspace with nested repositories has the same overlap inside one task. - **Capture a checkpoint when the baseline lookup fails** (pingdotgg#12307) — the case that silently leaves a turn with no restore point. - **Move the file-search refresh off the checkpoint path** (pingdotgg#12308) — it extended every capture by an index walk. - **Survive an empty nested repository, and clear a stale index lock** (pingdotgg#12181, `GitVcsDriver.ts`) — git cannot stage an embedded repository until it has a commit. The lock half matters most here: forced termination is the normal end of a sandboxed task. - **Bound the provider event log before serialization** (pingdotgg#12305, `EventNdjsonLogger.ts`) — otherwise it grows proportionally to tokens streamed. - **Keep usage totals across transcript cleanup** (pingdotgg#12304, `UsageService.ts`) and **resolve a contested fingerprint to the newest scan** (pingdotgg#10315, `usageMerge.ts`). Moatless serves `server.getUsageSummary` itself. - **Pass provider image attachments by path** (pingdotgg#11050, `CodexAdapter.ts`) — the turn/start request stops scaling with attachment size. A sandbox adds a hop, so an oversized request costs more there. - **Sweep stale worktrees and transcripts against retention rules** (pingdotgg#11598, `storageCleanup.ts`, with a workspace lease so two servers cannot sweep the same directory). A sandbox per task bounds the worktree half; transcripts outlive the sandbox. ## Verification `verify.mjs` — all 9 checks green on the first full pass, tests included (333 test files, 5071 tests). No flaky retries and no caveats. Contract drift: ADD 0 / DROP 0, so `packages/contracts/src/rpc.ts` needed no change. The `orchestration-decode-boilerplate` duplicate-add exception went stale — the colliding line is gone — and was deleted from `inventory.json` in this merge. Owned-concern sweep: the three new `apps/mobile/src/features/connection/` files are false positives, all upstream extracting shared mobile components out of files it already owned, with no fork delta in any of them. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --- Moatless task: https://moatless.soaplabstest.com/tasks/c83db5aa-7c47-47c6-93f4-fe2f6f9f548e
