Softlight Overview

Current PR UI

Design Score: 2/5

Suggested fixes

  • Commit diff buttons behave as single, self-contained controls consistent with the rest of the browser.
  • Parent commit links match the hover-only underline used by other commit links.
  • Make the per-file change dots reflect deletions so small edits don't look purely additive.
  • Aligns the files-changed summary with the file list so the commit page reads as one clean column.
  • Adds breathing room above the expanded commit description so it sits evenly within the commit header.

Redesign

The commit diff screens felt dense and noisy; this pass adds breathing room and a clear hierarchy so the actual changes stand out.

  • Cleaner commit header with a readable author + SHA line and a clear show/hide-description control.
  • Quieter diff and list rows that surface secondary actions only on hover, so changes lead.

Replacement Design Doctor reasoning-effort A/B clone for #2.

Variant: xhigh.

This branch adds a no-op commit on top of the original PR head so the file contents are equivalent while GitHub checks stay isolated to this test PR.

Replaces contaminated setup PR: #25.

Adds a `commit` pathType to the browse routes
(`/browse/<repo>@<branch>/-/commit/<sha>[/<file>]`) that renders a
placeholder CommitDiffPanel. Refactors browse path helpers into a
discriminated `BrowseProps` union so commitSha is required only for
pathType: 'commit'.

Wires up @codemirror/merge (via react-codemirror-merge) inside
CommitDiffPanel with a static before/after demo. Adds a CodeDiff
component that owns its language extension + view ref so each pane
can reconfigure its language compartment independently.

Also gates the react-grab dev scripts behind DEBUG_ENABLE_REACT_GRAP
so they don't load on every dev page render.

Replace the CodeMirror MergeView-based commit diff rendering with a DOM
based split-view that renders directly from git's hunks, inspired by
Chrome DevTools' DiffView. Per-file editor instances and the matching
getFileSource fetches are gone — a 50-file commit drops from ~100
network requests to 0, and per-row render cost from a full editor mount
to a synchronous Lezer highlight + grid emit.

- New `LightweightDiffViewer` builds a single 2-column subgrid with
  hunk headers spanning both sides; each cell uses `subgrid` so line
  numbers, markers, and content align across all rows.
- Pure helpers split out: `hunkParser` (body string → DiffLine[]),
  `splitPairing` (DiffLine[] → SplitRow[]).
- `presentableDiff` from @codemirror/merge supplies character-level
  intra-line diff highlighting on paired modifications.
- Lezer highlight code lifted from `lightweightCodeHighlighter` into
  `lib/codeHighlight` so both files share the helper.
- Drop `react-codemirror-merge` and `commitDiffEditor`. Long lines wrap
  via `whitespace-pre-wrap break-words` + `minmax(0, 1fr)` on the grid.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- File path header now sticks to the top of the scroll viewport while
  scrolling through that file's diff, using the negative-yOffset trick
  to compensate for the virtualizer's translateY positioning. Same
  pattern as searchResultsPanel/fileMatchContainer.
- Lightweight diff viewer's grid uses `minmax(<min>, max-content)` for
  line-number and marker columns so they don't collapse to zero width
  when one side of the diff is entirely blank (fully-added or
  fully-deleted files), keeping the right pane aligned across files.
- Drop the column gap between left and right panes and instead draw a
  `border-r` separator on the left cells for a cleaner divider.
- Hunk header gets an optional className so the first hunk renders with
  just `border-b` (the file header above already provides the top
  border), while subsequent hunks render with `border-y` between them.
- Drop the per-row footer padding in the virtualizer; rows now sit
  flush against each other.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- New `DiffStat` component renders GitHub-style additions/deletions
  counts with a 5-square indicator scaled log-ish to total change size.
  Added on the right of each file row header and on the right of the
  "N files changed" subheader for the commit total. Hidden when there
  are no line-level changes (pure renames).
- Each file row gets a `CopyIconButton` next to the path (copies
  newPath, falling back to oldPath) and a `CommitActionLink` that
  opens the file at the commit. Deleted files link to the old path
  at the parent commit so the user lands on the file's last existing
  state rather than a 404.
- `repoName`, `commitSha`, and `parentSha` are plumbed from the panel
  through `FileDiffList` to `FileDiffRow` to support the new link.
- `computeChangeCounts` is memoized per file in the row.

…nchoring

History panel rows in both the bottom panel and the commits page are now
clickable — they navigate to the matching commit diff via router.push,
with closest('button, a') short-circuit so inner action buttons keep
their own behavior. Bottom-panel history rows also highlight via
bg-accent when their commit is the one currently being viewed.

Commit diff header now uses AuthorsAvatarGroup + getCommitAuthors +
formatAuthorsText, matching latestCommitInfo and historyRow — co-authors
parsed from the commit body show up correctly.

When the URL trailing path matches one of the commit's files, that file
is moved to the top of the FileDiffList rather than scrolled to. Avoids
estimateSize-based scroll inaccuracy and works regardless of which side
of a rename the URL points to.

Lightweight diff viewer short-circuits with "Diff too large to display"
for files containing lines over 1000 chars, matching the cutoff in
lightweightCodeHighlighter.

PathHeader's breadcrumb measurement reserved 175px for "copy button and
padding"; the actual reservation needed is ~40px. Reduced so breadcrumbs
no longer collapse prematurely on wide layouts.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Lift `truncateSha` (was a private helper in getDiffToolComponent) to
  `lib/utils` so PathHeader can reuse it. The branch/ref display now
  renders a 40-char SHA as `abc1234`, preserving any `^` / `~N` suffix.
- Hide the `·` separator and the path's CopyIconButton when there's no
  path (repo root). Previously a dangling `·` and copy button rendered
  with nothing between them.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds a `path` query/tool parameter to restrict diff output to changes
touching a single file via git's `-- <pathspec>` separator. Refactors
the route handler to use the shared `getDiffRequestSchema`.

Fixes SOU-1154 (sourcebot-dev#1154)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Move single-file commit diffs from `/-/commit/<sha>/<path>` to
  `/-/blob/<path>?ref=<sha>&diff=true`, keeping the user's browsing
  revision in the URL. `/-/commit/<sha>` still renders the full
  multi-file diff.
- New `FocusedCommitDiffPanel` with status row (file status badge +
  authors + relative commit date + "View full commit" + DiffStat +
  exit-X) and path-filtered `getDiff` so only the single file's diff
  is fetched.
- New preview banner in `CodePreviewPanel` when `?ref=` is set, with a
  close button that strips the param.
- Make `PathHeader`'s revision clickable, linking to that ref's full
  commit view.
- New `HoverPrefetchLink` defers Next.js prefetching until hover; used
  in history rows to avoid firing many prefetches on render.
- Hide the bottom panel on `/-/commit/` views.
- Extract `getFileStatus` / `StatusBadge` to a shared `fileStatus.tsx`.
- Workaround Radix Tooltip + RSC re-render bug (drop `asChild` from
  `<TooltipTrigger>`, add `key={commitSha}`) so X / Browse-files
  buttons survive client navigation between commits.

Commit diff buttons sit inside an extra clickable wrapper

The close, exit-diff, and browse buttons in the commit diff view are each wrapped in an extra interactive layer instead of being a single self-contained control. This can add a redundant focus stop and make the buttons feel slightly off compared with the other icon and action buttons in the file browser. After the fix they should behave like one clean, consistent control.

Comment:
**Commit diff buttons sit inside an extra clickable wrapper**
The close, exit-diff, and browse buttons in the commit diff view are each wrapped in an extra interactive layer instead of being a single self-contained control. This can add a redundant focus stop and make the buttons feel slightly off compared with the other icon and action buttons in the file browser. After the fix they should behave like one clean, consistent control.

Issue:
All three new Tooltip-wrapped buttons render `<Tooltip><TooltipTrigger><Button asChild ...><Link>...`. Because TooltipTrigger (Radix Trigger) has no `asChild`, it renders its own <button> that wraps the Button's <Link> <a>, producing a nested button>anchor and an extra interactive wrapper around the control. Sites: fullCommitDiffPanel.tsx L79 (Browse files, outline/sm), focusedCommitDiffPanel.tsx L156 (Exit diff view, ghost/icon X), codePreviewPanel.tsx L105 (Close preview, ghost/icon X).

Suggested fix:
Add `asChild` to the three `<TooltipTrigger>` elements in fullCommitDiffPanel.tsx (L79), focusedCommitDiffPanel.tsx (L156), and codePreviewPanel.tsx (L105) so each tooltip merges into its single Button/Link, matching CommitActionLink.

Parent commit links stay underlined at rest

In the commit details line, the parent commit links are always underlined, while every other commit and revision link in the file browser only underlines when you hover. Matching the hover-only style would make these links feel consistent and a little less busy in the dense metadata row.

Issue:
commitHashLine.tsx L42: parent links use `className="underline hover:text-foreground"` — underline is always on and the only hover affordance is a color change.

Suggested fix:
Change the parent link className in commitHashLine.tsx from `underline hover:text-foreground` to `hover:underline` (optionally keeping the muted color), matching the historyRow and pathHeader SHA links.

Change dots can hide that a file also had deletions

On a file with one line added and one line removed, the little change-indicator squares show only the 'added' color, so at a glance the file looks purely additive even though its own +/- count clearly shows a removed line. The squares should agree with the count beside them.

Comment:
**Change dots can hide that a file also had deletions**
On a file with one line added and one line removed, the little change-indicator squares show only the 'added' color, so at a glance the file looks purely additive even though its own +/- count clearly shows a removed line. The squares should agree with the count beside them.

Issue:
DiffStat computes greenCount = Math.round((filled * additions) / total) and redCount = filled - greenCount. For a file with 1 addition and 1 deletion, filledSquaresForTotal(2) = 1 and Math.round(1*1/2) = 1, so greenCount = 1, redCount = 0, and the single filled square renders green (bg-green-500) with no red square, even though the same row prints '+1 -1'.

Suggested fix:
Allocate at least one square to each non-zero side before distributing the remainder (e.g. start greenCount/redCount at 1 when additions/deletions > 0 and filled permits, then split the leftover proportionally), so a file with deletions never shows an all-green single-square indicator.

Files-changed summary sits slightly out of line with the diff list

On the commit page, the "N files changed" summary is nudged in a few pixels more than the commit title above it and the file rows below it, so the left edge looks subtly ragged as you scan down the page. Aligning it with the file list makes the commit page read as one clean, deliberate column.

Comment:
**Files-changed summary sits slightly out of line with the diff list**
On the commit page, the "N files changed" summary is nudged in a few pixels more than the commit title above it and the file rows below it, so the left edge looks subtly ragged as you scan down the page. Aligning it with the file list makes the commit page read as one clean, deliberate column.

Issue:
The 'N files changed' summary bar uses px-4 (16px) horizontal padding, but the commit header above it uses p-3 (12px) and every FileDiffRow header below it uses py-2 px-3 (12px). The bar's content is therefore inset 4px on both the left and right relative to the column it labels, so 'N files changed' and its diffstat don't line up with the commit subject above or the file paths/diffstats below. The left edge of the page reads as subtly ragged when scanning down.

Suggested fix:
Change the summary bar's horizontal padding from `px-4` to `px-3` so its left and right edges align with the commit header (`p-3`) above and the file diff rows (`px-3`) below, giving the page a single consistent content column.

Expanded commit description hugs the title with no breathing room

When you expand the commit description on the commit page, the description panel butts directly against the commit title with no separation, while the author and commit lines below it have clear spacing. A small gap above the description matches the surrounding rhythm and makes the expanded state feel balanced rather than crowded.

Comment:
**Expanded commit description hugs the title with no breathing room**
When you expand the commit description on the commit page, the description panel butts directly against the commit title with no separation, while the author and commit lines below it have clear spacing. A small gap above the description matches the surrounding rhythm and makes the expanded state feel balanced rather than crowded.

Issue:
When the commit description is expanded, the rounded, tinted CommitBody panel sits flush against the bottom of the commit subject (h1) with 0px separation, while the author row and hash row below it are separated by the header's gap-2 (8px). The expanded body is nested inside the subject row, so it bypasses the header's vertical gap, producing an uneven rhythm: the description card touches the title above but has space below it.

Suggested fix:
Add `mt-2` to the expanded CommitBody className in commitMessage.tsx (`"mt-2 rounded max-h-[40vh] overflow-y-auto"`) so the description panel is separated from the subject by the same 8px the header already uses between its other stacked rows. This is scoped to the commit page; the commit-history-row usage passes its own className and is unaffected.

  • Cramped header and a tiny SHA line became a spacious header with a bold subject, one legible author + date line, and copyable commit/parent SHA chips.
  • Always-on copy and 'view at commit' icons on every file row now reveal on hover, so the path, status badge, and +/- counts read cleanly.
  • Heavy gray slabs on the empty side of the split diff were softened so added/removed lines lead the eye.

Commit description: framed card and a clear open/close chevron

Commit description

Before · After

  • The description used to appear as faint, unframed text; it now sits in a clean bordered card with comfortable padding.
  • The ambiguous '...' control became a chevron that rotates to clearly signal expanded vs. collapsed.

Focused diff: a clear left/right split between context and actions

Focused diff

Before · After

  • Status, author, date, diffstat, 'view full commit', and close were crammed into one busy row; they're now grouped into a readable left (what changed, by whom) and right (counts + actions) layout.
  • Softened empty diff halves keep the few changed lines as the focal point.

Preview banner: a soft tinted notice so you know you're on an old revision

Preview banner

Before · After

  • The plain-text 'Previewing file at revision' line blended into the page; it's now a soft tinted band with a history icon.
  • The revision SHA stands out as a clear monospace link.

Commit history: quiet date labels and a distinct hover so rows feel clickable

Commit history

Before · After

  • A hovered row used the same shade as the date header and looked like a heading; the date is now a quiet uppercase section label and hovered rows get a clearly distinct highlight.
  • Per-row copy and 'view at commit' icons reveal on hover, leaving the subject, author, and SHA clean by default.

Context:
Across the commit diff viewer, the original screens crowded every detail at once: a cramped header, an ambiguous '...' button, copy and link icons on every row, heavy gray blocks filling the empty side of each diff, a preview banner that was easy to miss, and a hovered commit that looked just like a date header. The pass gives each screen room to breathe, leads with the one thing that matters (the commit and its changes), tucks secondary actions behind hover, and uses light tints and a clear icon so state messages read as notices. The result is calmer, easier to scan, and closer to a polished code-review tool.

What the Designer's pass changed:
- Full commit page: the header was pinched and the metadata was a tiny, hard-to-read line. It now has room to breathe with a bold subject, a single legible author + date line, and neutral commit/parent SHA chips you can copy.
- Full commit page: file rows were busy with an always-visible copy icon and a 'view at commit' icon competing with the path and counts. Those now appear only when you hover a row, so the file name, status, and +/- counts read instantly.
- Full commit page: the blank half of each side-by-side diff was a heavy gray slab. It's now a faint fill, so added and removed lines are what your eye lands on.
- Expanded description: the commit body used to drop in as faint, unframed text. It now sits in a clean bordered card with a chevron that clearly shows open vs. closed.
- Focused single-file diff: the status, author, date, and actions were jammed into one busy row. They're now grouped into a clear left (what changed, by whom) and right (counts, view full commit, close) layout.
- Preview banner: 'Previewing file at revision' was plain text that blended into the page. It's now a soft tinted notice with a history icon, so it's obvious you're viewing an older version.
- Commit history: a hovered row used the same shade as the date header, so it looked like a heading. The date is now a quiet uppercase section label, and hovered rows get a distinct highlight with copy/view actions revealed on hover.

Remaining issues

  • The focused single-file diff (browse.blob.diff_focused) shows empty space below a very short (3-line) diff. This is inherent to the data, not the layout; a professional layout for a 3-line file would look the same.
  • Diffstat mini-squares are intentionally kept beside the +/- numbers because the capture spec explicitly requires '+N/-N diffstat squares' (mirrors GitHub).
  • The designer's pass agent reported post-implementation screenshots that do not appear in Read tool usage.
