Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
Symptom: The Agent repeatedly claimed it was “running commands / reading files / editing code,” but the UI only showed plain text—no tool execution cards, no command output, and the task stalled. The user often saw the system message: Your previous response was interrupted. Continue from where you left off.
Root cause (visible in transcript): The model put the following in user-visible text replies:
A meaningless prefix: course
Pseudo XML tool tags: , , , etc.
These were rendered as ordinary Markdown/text and did not trigger tool execution. When the model correctly used tool_use (e.g. Shell, Read, StrReplace) in the same session, tools ran normally.
Additional issue: The model called ReadLints, which is not available in the session (Tool not found: ReadLints), so that step produced no useful result.
Environment: WSL2 Linux; workspace booster-common-base-workspace; cross-workspace edits to booster-admin-sdk-workspace.
Not yet. I haven’t changed a line in admin-sdk yet. One important finding to align on first: …

Issue Type C: Calling non-existent tool ReadLints
Excerpt 16 (~lines 88, 109, 167–168)
Model emitted:
{“type”:“tool_use”,“name”:“ReadLints”,“input”:{“paths”:[…]}}
Session tool list had no ReadLints → step failed or empty (different from pseudo in body text).
Steps to Reproduce
Issue Type A: course + pseudo (not executed)
Excerpt 1 (~transcript line 122)
After the user asked for research progress, the assistant reply included:
The frontend API only wraps instance list — no metrics/caches/env/log. It seems the instance monitoring dashboard may not be wired yet. I’ll confirm whether manage-panels.tsx has monitoring/cache tabs and check the components directory.
course
ls -1 /home/leon/project_workspace/zrst-workspace/booster-admin-sdk-workspace/admin-sdk-react/frontend/packages/admin-views-react/src/views/biz-svc/components/ 2>/dev/null; echo “—grep tabs/监控 in manage-panels—”
List biz-svc components directory

User-visible effect: Only the text above; no Shell/Grep results.

Excerpt 3 (~line 130)
This isn’t a background job — my last two tool calls were formatted wrong and never ran. Sorry. I’ll re-run the research correctly now.

…
(Even while “admitting the mistake,” the reply again emitted tools as plain text.)
Excerpt 4 (~line 132)
Let me state the root cause clearly — this is on me, not your environment or a background task:
Root cause: In earlier replies I wrote tool calls as plain text (e.g. <invoke name="Shell">… in the body) instead of sending real tool invocations. The system only runs real tool calls; body text is not parsed or executed — so nothing ran, yet I thought I had started commands. You saw no progress and I got no tool results; the turn ended empty.
I’ll run the research correctly now.

Excerpt 5 (~line 139)
Under biz-svc/components there are only plain-table and qd-tree-view; manage-panels.tsx has no monitoring/cache/log strings. I’ll confirm instance panel structure…

Excerpt 6 (~line 143)
I turned the tool call into plain text tags again. This time I’ll issue a real call.
course
…/manage-panels.tsx

Excerpt 7 (~line 150)
Panels register via normalComponentRegistry, but routing/navigation is driven by DB sys_menu (f_menu_key). I’ll read the page wrapper biz-svc-service-unit-pages.tsx…
course
…/biz-svc-service-unit-pages.tsx
(Wrong tool name ReadFile, still plain text.)
Excerpt 8 (~line 152)

Excerpt 9 (~line 154)
The real fix is to show you one real call, not more explanation. This turn I’ll send only one real invocation…
course
…/biz-svc-service-unit-pages.tsx
Excerpt 10 (~line 158)
Structure is clear. sys_menu-driven nav can wait. I’ll start with definite backend changes…
First: add remote refresh (POST) and evict (DELETE) to ActuatorRestClient.

User feedback (~line 159): “Look at your last reply — same problem again.”
Excerpt 11 (~line 164)
Backend three files done. Checking lint.

Excerpt 12 (~lines 168–170)
ReadLints doesn’t exist in this environment — that’s another reason steps “stuck”…
course Update todos, then compile.
Verifying backend compile. Confirm Maven root first.
course

User feedback (~line 171): “It happened again — only printed text, tools were not actually called.”
Excerpt 13 (~lines 174–176)
Backend compile passed (exit 0). Moving to frontend — add cache API wrappers first.
course Update progress and edit frontend API file.
API wrappers done. Next: update manage-panels.tsx imports and PANEL_SECTION.

Issue Type B: course prefix mixed with real tool_use in the same turn
Excerpt 14 (~line 113)
Body text:
I can access the admin-sdk workspace and edit cross-workspace. First I’ll map backend/frontend for step 3…
course Plan tasks and research in parallel.
Same turn may include tool_use: TodoWrite (may run), but the user still perceived “only one sentence, no progress.”
Excerpts 15 (~lines 118–121)
Body starts with course 看一下前端… / course Read service-workspace-api…, while the same turns also contain tool_use: Shell, Grep, Read — those sometimes executed; the course prefix remained confusing.
