Make completed desktop tool rows read like useful activity labels instead of raw plumbing: terminal rows use a dispatch-style shell summarizer for agent wrappers, and read_file rows keep the action plus filename and requested line range.
The shell cleanup follows condensed-milk-pi's shape: split command compounds on real separators, strip pipe tails inside each segment, clean redirects/env prefixes, then classify setup/banner/status segments. Multi-command probes render as `first command + N commands`; the full command remains available in copy/detail.
Read rows now render as `Read package.json` or `Read main.ts L25-34`, using requested positive offset/limit and returned line numbers only as fallback for negative/unknown offsets.
ToolFallback rebuilt the `part` wrapper every render, defeating the
buildToolView memo and re-running a full JSON.stringify of the result on
every ~33ms stream delta. A /learn over a large directory (many ~100KB
tool results) saturated the renderer main thread (hang/throttle) and
spiked memory until it OOMd (crash).
- Re-derive a stable `part` from the referentially-stable args/result so
the view/copy memos hold across deltas.
- Clamp every inline-painted payload (detail, stdout/stderr, rawResult,
technical trace) to MAX_TOOL_RENDER_CHARS; the row's Copy button still
reads the uncapped view.detail for the full output.
Render write_file/edit_file/patch as a reviewable diff instead of raw
result JSON, closer to a Cursor/T3 per-edit review.
- Unified diff via FileDiffPanel: strip git file-header + @@ hunk noise,
drop the +/- gutter, color by line with a 2px gutter accent, full-bleed
to the card, transparent context lines, compact scroll height.
- Header shows filename + language icon + +N/-N stats; full path moves to
a hover tooltip (no Edited verb, no ms).
- Treat the three file-edit tools uniformly (isFileEditTool); read diff
from inline_diff or patch's diff field; suppress raw-arg detail.
- Reusable FileTypeIcon primitive sharing the code-block icon mapping
(codiconForFilename), codicon fallback.
- Per-row scaffolding fade (not the group wrapper, which trapped child
opacity); expanded edits stay full, collapsed fade; keyboard-only focus
lift. Hide diff-less rehydrated creates that read as dupes.
- clarify-tool: top-align the help icon (items-start + mt-px) so it sits
beside the first line of a multi-line question instead of floating
centered against the whole block.
- tool-fallback: a non-zero exit code alone no longer paints the whole
terminal/execute_code card red. grep no-match, diff differences, and
piped commands routinely exit non-zero while producing useful output;
only flag an error when the command produced no output. Explicit error
signals (error field, success=false, status=error, isError) still go red.
- Add regression tests covering the exit-code -> status matrix.
* feat(desktop): drop files anywhere in the chat area
File drops were only wired to the composer input. Add a reusable
useFileDropZone hook (enter/leave depth counting + capture-phase reset so
the affordance clears even when the composer claims the drop) and a
pointer-events-none ChatDropOverlay, wired onto the conversation viewport.
Drops funnel through the existing onAttachDroppedItems; composer drops keep
their own inline-ref behavior.
* fix(desktop): chat-area drops insert inline @file refs, not attachment cards
Match the composer-input drop behavior — funnel dropped paths through
droppedFileInlineRef + the composer insert bus so they render as inline
ref chips instead of attachment cards.
* fix(desktop): don't render bare file paths as tool images (404)
vision_analyze reports its input image as a local filesystem path, which
toolImageUrl handed straight to <img src>. In the renderer that resolves
against the dev-server origin and 404s. Restrict inline tool images to
fetchable sources (data: URLs and remote http(s)); bare paths now fall
back to the tool's codicon.
