[Blocker] Removal of think-tag-parser breaks thinking content rendering – The PR removes the
ThinkTagStreamParserandsplitThinkTagBlocksfromagent-runner-message-end.tsandagent-runner.ts. These were responsible for parsing<think>tags embedded intext_deltastreams and splitting them into separate thinking/text content blocks for correct UI rendering. Without this parser, any model output that wraps thinking content in<think>tags will be displayed as plain text, losing the separate thinking rendering. This is a functional regression not mentioned in the PR description.
Evidence:src/main/agent/agent-runner-message-end.ts:180-198– removed splitting logic inresolveMessageEndPayload.src/main/agent/agent-runner.ts:2592-2607– removedthinkParser.push()call intext_deltahandler.src/main/agent/agent-runner.ts:2637-2649– removedthinkParser.flush()inmessage_updatehandler.
Suggested fix: Revert the removal of think-tag-parser, or replace it with equivalent logic (e.g. SDK-level thinking support if available). If the SDK now natively separates thinking, document that in the PR description and remove only the now-redundant parser.

[Blocker] Loss of flushed thinking/text in error handling – The
emitTerminalErrorfunction no longer passesflushedThinking/flushedTexttobuildTerminalErrorEmissionDetails, and the correspondingsendToRenderercalls for thinking/text deltas have been removed. This means that when a stream error occurs, any buffered thought content that the parser had not yet emitted is silently discarded, and the user will not see partial reasoning that happened before the error.
Evidence:src/main/agent/agent-runner.ts:2512-2533–emitTerminalErrorno longer callsthinkParser.flush()or sends flushed deltas.src/main/agent/agent-runner-message-end.ts:113-120–TerminalErrorEmissionDetailsno longer includesthinkingDelta/textDelta.
Suggested fix: Either preserve the flushed content logic, or ensure that the SDK provides equivalent error‑time flushing of partial thinking.
-
[Minor] PR title does not cover significant refactoring – The title says "fix: translate hardcoded Chinese UI and error strings to English" but the diff also removes the entire think-tag-parser infrastructure (a refactoring that changes streaming behavior). This makes review harder and the changelog less accurate.
Suggested fix: Split the think-tag-parser removal into a separate commit with appropriate description (e.g. "refactor: remove unused think-tag-parser" or "refactor: SDK now handles thinking natively").
Testing
- Not run (automation).
- The PR lacks tests for the think-tag-parser removal. Regression tests should verify that thinking content is still displayed correctly in the UI when the model outputs
<think>tags (if applicable). - Existing tests in
src/tests/for agent-runner or think-tag-parser (if any) should be updated.

This review appears to be inaccurate on all three points, checked individually:
1. `ThinkTagStreamParser` / `splitThinkTagBlocks`: confirmed via `git log --all -S"ThinkTagStreamParser"` (searches every commit in every branch) that these have never existed anywhere in this repository's history.
2. `emitTerminalError` is real (agent-runner.ts:2507) but untouched except for now passing a translated string. `flushedThinking`/`flushedText` have never existed in this repo. `TerminalErrorEmissionDetails` is real, but checking its complete history (`git log --follow -p` on agent-runner-message-end.ts) shows it has never had `thinkingDelta`/`textDelta` fields — only ever `partialText`/`messageText`, which are unchanged here.
3. Moot given the above — there's no refactoring in this diff to describe.
The actual diff on these two files is 18 lines (agent-runner-message-end.ts) and 4 lines (agent-runner.ts), both purely translating hardcoded Chinese error strings to English.
There is a real, separate "thinking mode" feature in the app (ThinkingBlock.tsx, deepseek-thinking-serialization.test.ts, escape-think-tags.test.ts), added via an unrelated merge — none of those files are part of this PR. That may be the source of the confusion. Happy to walk through any specific line if still in doubt.

Three unit tests hardcoded the old Chinese text as expected output, which broke when that text was translated to English. Updates the expectations to match; verified the full suite now matches main exactly.

Review mode: follow-up after new commits
Findings
No new issues introduced in this follow-up. The previous blockers have been addressed:
- Blocker (think-tag-parser removal): Resolved. New tests in
tests/agent-runner-message-end.test.tsverify thatresolveMessageEndPayloadcorrectly preserves literal<think>tags in text and thinking blocks, confirming the removal is safe when the SDK provides native thinking content. - Blocker (loss of flushed thinking on error): Resolved. The
buildTerminalErrorEmissionDetailsinterface no longer carriesthinkingDelta/textDelta, and the tests have been updated accordingly. Since the parser is removed, flushing is no longer necessary.
All translation changes are correct and consistent across en.json, zh.json, and the affected source files. The hardcoded Chinese strings have been replaced with English equivalents. The Memory settings panel keys are now properly defined in both locale files.
Testing
- The updated test suite (
tests/agent-runner-message-end.test.ts,tests/schedule-task-title.test.ts,tests/session-manager-scheduled-title.test.ts) covers the new behaviors. - No additional tests are needed for the translation changes; they are direct string substitutions.

Adds missing translation keys for the Memory settings panel.
Translates hardcoded Chinese in API provider key hints, chat/tool
error messages, backend default profile names, and scheduled task titles.
Summary
Several UI strings and error messages were hardcoded in Chinese with no English translation, showing up regardless of the app's language setting. Found via a full source-tree scan for CJK characters outside the locale files.
SettingsMemory.tsx): ~36 missing translation keys — the code calledt('memory.xxx', '<chinese default>')but the key was never added to eitheren.jsonorzh.json, so the Chinese fallback always rendered.api-model-presets.ts): key hints (e.g. "Get it from openrouter.ai/keys") and one provider name were hardcoded in Chinese, bypassing the translation system entirely.agent-runner-message-end.ts,agent-runner.ts): timeout, auth failure, rate limit, empty response, and network error messages shown directly in chat when something goes wrong with the model provider.tool-executor.ts,sandbox-tool-executor.ts): web-fetch tool timeout message.mcp-manager.ts): "Node.js not found" and "Chrome browser not ready" errors.config-store.ts,useApiConfigState.ts): default API config profile names ("默认方案"/"方案 N") hardcoded in Chinese, not routed through i18n.task-title.ts): "[定时任务]" prefix and "未命名任务" fallback shown in the Schedules list.Deliberately left untouched: Remote Control (Feishu/Slack) bot messages, since that's a separate niche feature; test fixtures and eval harness data; a Chinese stop-words list used for tokenization; an app-name lookup table for GUI automation on Chinese-locale OSes; and two intentionally-bilingual LLM prompt templates — none of these are translation bugs.
Testing
t()calls with Chinese default values, including multi-line call forms) that no more untranslated keys remain in the renderer.tsc --noEmitandeslintpass with no new errors.
