AI-3821 — no GitHub issue

What & why

A bash ls was classified as a file search, so a group of listings and a file read said "Searched files, read a file" and each ls row read "Searched files ls -la". ls now counts as a command: the group says "Ran commands, read a file" and the row "Ran command ls -la".

Where to look

The kind chip and header of a lone ls call read "Command" rather than "Search".

Verification

• ToolSummaryTests (61), ChatTabViewModelTests (214), ChatTabViewSmokeTests (88): 0 failed.
• Headless render of an ls -la src + ls /missing + Read group shows "Ran commands, read a file".

Walkthrough

Tool-call rows now distinguish commands, paths, and searches. They support expandable command and result content. Results have line and character limits, truncation notices, and error fallback text. The view model, view, and tests cover the new behavior.

Changes: Tool Call Details

Layer / File(s)	Summary
Extract and format tool details src/Capacitor.App/ViewModels/TextElision.cs, src/Capacitor.App/ViewModels/ToolDetail.cs, src/Capacitor.App/ViewModels/ToolSummary.cs, test/Capacitor.App.Tests.Unit/ToolDetailTests.cs, test/Capacitor.App.Tests.Unit/ToolSummaryTests.cs	Path values use tail elision with a 56-character limit. Other details retain middle elision. Tool inputs expose path and command information. File-listing hints map to Command.
Store command and result state src/Capacitor.App/ViewModels/ChatItems.cs, src/Capacitor.App/ViewModels/ChatTabViewModel.cs	Tool-call items store command and path metadata, result content, truncation notices, and error state. Result handling passes both payload and error status.
Render and validate expanded tool calls src/Capacitor.App/Views/ChatTabView.axaml, test/Capacitor.App.Tests.Unit/ChatTabViewModelTests.cs, test/Capacitor.App.Tests.Unit/ChatTabViewSmokeTests.cs, test/Capacitor.App.Tests.Unit/ToolGroupItemTests.cs	The view renders expandable command and result details with path styling and scrolling. Tests cover path eligibility, result limits, scrolling, error fallback text, and updated command summaries.

Merge Risk: Low · up to 76c2b

Some failed commands can expand without an explanation, and some array-form commands can lack expanded command text. These bounded display issues do not otherwise block merging.

Security architecture risk: Minimal · up to 76c2b

The expanded content remains within the existing chat view and is displayed as plain text with size limits. The reviewed changes do not add tool permissions, execution capabilities, or external recipients. No material security risk was identified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated exposure increase is greater visibility of existing transcript content to the current chat viewer. The inspected expansion path adds no recipient or tool authority.

Trust Boundaries and Controls

• observed — Expansion remains inside the tool-group visibility boundary. Pending-question suppression still applies to the group, and permission answers remain owned by the separate permission card.

Resilience and Maintainability Implications

• observed — Results update the matched pending tool item. Removing that pending entry prevents repeated results from updating the settled item; feed changes and resets clear ownership maps, while generation checks reject stale feed updates. These existing controls also contain the newly displayed result state.

Keep the existing tool-call and group view models as the owners of row state: this adds expansion without a separate result viewer or a new grouping pipeline. Those alternatives add complexity without a clear benefit for this scope.

2. Some paths starting with an emoji crash row building ✓ Resolved

Description

In PathTail, a leading high surrogate can decrement head from 1 to 0, after which the head < 1
branch requests max - 1 characters from a tail only max - 2 characters long. A path beginning
with a supplementary Unicode character and having a 54-character final parent-and-file suffix
triggers ArgumentOutOfRangeException while a tool-call event is projected, so its row is not
built.

Code

src/Capacitor.App/ViewModels/TextElision.cs[R26-28]

+        var head = max - tail.Length - 1;
+        if (head > 0 && char.IsHighSurrogate(text[head - 1])) head--;

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

When tail.Length is max - 2, the calculation gives head a value of 1; the leading-surrogate
check can decrement it to 0. The resulting head < 1 branch slices max - 1 characters from the
shorter tail, which is out of range. ToolDetail.From invokes this helper for path keys and
catches only JSON parsing errors.

4. Non-path details lose trimming when the input has a path field ✓ Resolved

Description

ShowsPath checks the input JSON on its own terms, while the displayed detail may come from
ForKey, FirstOrAny or the tool-search formatter, which never run PathTail. A catalogued or
foreign tool whose input has a path/file_path field gets the path class, so its 80-character
detail is shown with no trimming and gets clipped.

+                        var item = new ToolCallItem(name, detail, category, label, entry?.Card ?? ToolCardKind.None, e.ToolInputJson,

5. Multi-line commands lose their later lines ✓ Resolved

Description

CommandOf reads through RawForKey, whose FirstLine call discards everything after the first
newline before the expanded command body is built. For heredocs, multi-line scripts, and
backslash-continued commands, the body shows only a partial command; if that first line matches the
row detail and the result is empty, HasCommandBody is false and no expand control appears.

Code

+        if (command.Length == 0) command = RawForKey(inputJson, "cmd");

RawForKey ends with FirstLine(s), which cuts at the first \r or \n; CommandOf uses that
value, so its 2000-character cap cannot preserve later lines. The expanded view binds CommandText,
while the expand control depends on HasCommandBody or a result, explaining why a first line equal
to Detail with an empty result leaves the remaining command inaccessible.

6. Huge single-line output is kept in full ✓ Resolved

Description

SetResult only limits the number of lines, so a single-line result (minified JSON, base64, a long
log line) is stored in ResultText uncut. It is held for every tool call in the session and laid
out in a wrapping text block when the row is opened. The 4096-character check only adds a notice and
doesn't shorten the text.

+                body = body[..newline];

7. Long paths lose their file name when the pane is narrow ✓ Resolved

The .toolLine.path style turns off TextTrimming but doesn't enable wrapping. When the pane is
narrower than the 56-character PathTail output, the end of the path is clipped, and that end is

extraction only for the compact row detail, and keep the existing fallback from
command to cmd.

Review comments at @src/Capacitor.App/Views/ChatTabView.axaml:
- Line 94: Update the expanded result layout around the MaxHeight setter so the
result text is wrapped in a height-limited ScrollViewer. Remove the height limit
from the text control itself, preserve the existing expanded-result content and
SetResult behavior, and ensure long results can scroll within the constrained
area.

- Line 221: Update the button’s AutomationProperties.Name binding near the
existing “Toggle tool details” value so it identifies the tool and dynamically
switches between “Show” and “Hide” based on IsExpanded. Preserve the button’s
toggle behavior while ensuring screen readers receive the current expansion
state.

🟡 Minor · Apply the failure fallback after trimming the result. · ChatItems.cs:230-233

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Apply the failure fallback after trimming the result.

If a failed tool returns only \r or \n, TrimEnd makes body empty after the fallback check. HasResult then becomes false, so the expanded row shows neither the error heading nor an explanation. Trim first, then apply "The tool failed." when the result is empty.

Update the body-processing logic in the ChatItems view-model to trim trailing
carriage returns and newlines before checking whether the result is empty. Then
apply the error fallback text “The tool failed.” when error is true and the
trimmed body is empty, preserving non-error empty results as null.
