+# OpenSpec Spec: Web UI Component Cleanup — Inline Styles, Forms, Badges
+
+## Change
+`web-ui-spacing-typography-rework` — Pass 2: Component Cleanup
+
+## Parent Proposal
+`openspec/proposals/web-ui-spacing-typography-rework.md`
+
+## Parent Spec
+`openspec/specs/web-ui-spacing-typography-rework.md`
+
+## Status
+spec
+
+---
+
+## 1. Scope of This Spec
+
+This spec covers **Pass 2 (Component Cleanup)** only:
+
+- Refactor static inline styles in the highest-volume editor/sidebar components into token-based utility classes.
+- Replace hardcoded `280px` sidebars with the `--sidebar-width` token.
+- Unify `.form-group` and `.form-field` into a single pattern.
+- Consolidate status badges/chips into a single `.status-badge` family.
+- Add the missing utility classes needed by the refactor (`.stack-*`, `.row-*`, `.card-*`, `.form-section`, `.form-row`, `.form-help`, `.text-error`, `.muted`, `.ghost-button`, `.secondary-button`, `.dialog-actions`).
+
+Out of scope for Pass 2:
+- Token additions (Pass 1, already done).
+- Missing primitive classes like `.btn` or `.alert` (Pass 1, already done).
+- Modal/dialog unification (Pass 3).
+- Card consolidation across page CSS files (Pass 3).
+- Breakpoint standardization beyond sidebar width (Pass 3).
+
+---
+
+## 2. Components to Refactor
+
+The following components have high inline-style counts and must be refactored to use utility classes. **Only static layout styles should move to CSS**; dynamic values (e.g. drag-over background, computed widths) may remain inline.
+
+### 2.1 `apps/web/src/components/features/tool/manifest-editor.tsx` (~70 inline styles)
+
+Typical patterns:
+- `display: "flex", gap: "..."` → `.row`, `.row-sm`, `.row-md`, `.stack`, `.stack-sm`, `.stack-md`
+- `padding: "..."` → `.p-2`, `.p-3`, `.p-4`
+- `marginBottom: "..."` → `.mb-2`, `.mb-3`, `.mb-4`
+- `background: "var(--panel)"` → `.card`, `.card-sm`, `.card-md`
+- `borderRadius: "0.375rem"` / `10px` → `.rounded-md`, `.rounded-lg`
+- `border: "1px solid var(--border)"` → `.card` already provides it
+- `fontSize: "0.875rem"` → `.text-sm`
+- `fontFamily: "monospace"` → `.font-mono`
+- `flex: 1` → `.flex-1`
+- `overflow: "auto"` → `.overflow-auto`
+- `textAlign: "center"` → `.text-center`
+- `justifyContent: "space-between"` → `.justify-between`
+- `alignItems: "center"` → `.items-center`
+- `cursor: "pointer"` → `.cursor-pointer`
+
+Required new utilities:
+- `.row`, `.row-sm` (gap: `--space-2`), `.row-md` (gap: `--space-3`), `.row-lg` (gap: `--space-4`)
+- `.stack`, `.stack-sm`, `.stack-md`, `.stack-lg`, `.stack-xl`
+- `.items-start`, `.items-center`, `.items-end`
+- `.justify-between`, `.justify-center`, `.justify-end`
+- `.flex-1`, `.flex-none`
+- `.text-center`, `.text-left`, `.text-right`
+- `.font-mono`
+- `.cursor-pointer`
+- `.overflow-auto`, `.overflow-hidden`
+- `.p-1` through `.p-5`, `.px-*`, `.py-*`
+- `.m-0`, `.mb-1` through `.mb-6`, `.mt-*`, `.ml-*`, `.mr-*`
+- `.w-full`, `.min-w-0`, `.max-w-prose`, `.max-w-form`
+- `.rounded-sm`, `.rounded-md`, `.rounded-lg`, `.rounded-xl`, `.rounded-full`
+
+### 2.2 `apps/web/src/components/features/config-profiles/ConfigProfileEditorPanel.tsx` (~51 inline styles)
+
+Same utility patterns as above. In addition:
+- Replace inline success-banner styles with `.alert-success` (add if missing).
+- Replace inline drag item styles with `.drag-item`, `.drag-item-active` utilities.
+- Replace inline sticky dialog-actions styles with the existing `.dialog-actions` class plus a `.sticky-footer` modifier if needed.
+
+### 2.3 `apps/web/src/components/features/tool-workshop/ToolTypeEditorPanel.tsx` (~20 inline styles)
+
+Same patterns as ConfigProfileEditorPanel. The empty-state and form header styles should use shared utilities.
+
+### 2.4 `apps/web/src/components/features/tool-workshop/ToolTypeListSidebar.tsx` (~12 inline styles)
+
+- Replace `style={{ width: "280px", minWidth: "280px" }}` with `style={{ width: "var(--sidebar-width)", minWidth: "var(--sidebar-width)" }}` or a `.sidebar` class.
+- Replace list-item inline spacing with `.sidebar-item` utilities.
+
+### 2.5 `apps/web/src/components/features/config-profiles/ConfigProfileListSidebar.tsx` (~14 inline styles)
+
+- Same sidebar width change as ToolTypeListSidebar.
+- Replace inline badge styles with `.badge`/`.badge-secondary`.
+- Replace inline delete button styles with `.ghost-button.small` or `.btn-icon`.
+
+### 2.6 `apps/web/src/components/features/git/git-mount-editor.tsx` (~31 inline styles)
+
+Same stack/row/card/gap/padding/margin utilities as manifest-editor.
+
+---
+
+## 3. Sidebar Width Tokenization
+
+Both sidebars currently hardcode `280px`. Change to use the token introduced in Pass 1.
+
+### Option A: Inline style with CSS variable
+
+```tsx
+<div style={{ width: "var(--sidebar-width)", minWidth: "var(--sidebar-width)" }}>
+```
+
+### Option B: Utility class
+
+```css
+.sidebar {
+  width: var(--sidebar-width);
+  min-width: var(--sidebar-width);
+  display: flex;
+  flex-direction: column;
+  border-right: 1px solid var(--border);
+  background: var(--panel);
+}
+```
+
+Use **Option A** if the surrounding layout already has custom styles; use **Option B** if the sidebars can share more structure. The spec requires at minimum that `280px` is replaced by `var(--sidebar-width)`.
+
+---
+
+## 4. Form Pattern Unification
+
+### Current state
+
+- `.form-group` exists in `global.css` and is widely used.
+- `.form-field` exists with nearly identical rules and is used in newer components.
+
+### Target state
+
+- Keep **`.form-group`** as the canonical class.
+- Deprecate `.form-field` by making it an alias:
+
+```css
+.form-field {
+  /* alias for backward compatibility */
+  composes: form-group; /* not supported in plain CSS; instead duplicate the rule or remove .form-field usage */
+}
+```
+
+Because plain CSS does not support `composes`, do one of:
+
+1. **Preferred**: keep both selectors in the same rule block:
+   ```css
+   .form-group,
+   .form-field {
+     display: flex;
+     flex-direction: column;
+     gap: var(--space-2);
+     margin-bottom: var(--space-4);
+   }
+   ```
+2. Then migrate callers from `.form-field` to `.form-group` in a follow-up cleanup task (not this pass).
+
+### Add missing form utilities
+
+```css
+.form-section {
+  padding: var(--space-4);
+  background: var(--panel);
+  border: 1px solid var(--border);
+  border-radius: var(--radius-md);
+}
+
+.form-section > h4:first-child,
+.form-section > h3:first-child {
+  margin-top: 0;
+}
+
+.form-row {
+  display: flex;
+  align-items: flex-start;
+  gap: var(--space-3);
+}
+
+.form-row .form-group {
+  flex: 1;
+  margin-bottom: 0;
+}
+
+.form-help {
+  font-size: var(--font-size-sm);
+  color: var(--muted);
+  line-height: var(--line-height-normal);
+}
+
+.text-error {
+  color: var(--danger);
+  font-size: var(--font-size-sm);
+}
+```
+
+---
+
+## 5. Status Badge Consolidation
+
+### Current state
+
+Status colors are duplicated across `.status-badge` (utilities.css), `.instance-chip` (global.css), and inline styles.
+
+### Target state
+
+Create a single `.status-badge` family in `global.css`:
+
+```css
+.status-badge {
+  display: inline-flex;
+  align-items: center;
+  gap: var(--space-1);
+  padding: var(--space-1) var(--space-2);
+  border-radius: var(--radius-full);
+  font-size: var(--font-size-xs);
+  font-weight: 600;
+  text-transform: capitalize;
+  line-height: var(--line-height-tight);
+  background: var(--bg);
+  color: var(--muted);
+  border: 1px solid var(--border);
+}
+
+.status-badge::before {
+  content: "";
+  width: 6px;
+  height: 6px;
+  border-radius: 50%;
+  background: currentColor;
+}
+
+.status-badge--running,
+.status-badge--success {
+  background: var(--success-light);
+  color: var(--success);
+  border-color: color-mix(in srgb, var(--success) 30%, transparent);
+}
+
+.status-badge--error,
+.status-badge--failed {
+  background: var(--danger-light);
+  color: var(--danger);
+  border-color: color-mix(in srgb, var(--danger) 30%, transparent);
+}
+
+.status-badge--warning {
+  background: var(--warning-light);
+  color: var(--warning);
+  border-color: color-mix(in srgb, var(--warning) 30%, transparent);
+}
+
+.status-badge--info,
+.status-badge--pending,
+.status-badge--idle {
+  background: var(--info-light);
+  color: var(--info);
+  border-color: color-mix(in srgb, var(--info) 30%, transparent);
+}
+```
+
+Then update callers to use `.status-badge` + `.status-badge--<variant>` instead of `.instance-chip` or inline status colors. Keep `.instance-chip` as a deprecated alias for one pass if it is widely referenced; do not delete it yet.
+
+---
+
+## 6. Required New Utility Classes
+
+Add to `apps/web/src/styles/utilities.css` unless they fit better in `global.css`.
+
+### 6.1 Layout utilities
+
+```css
+.row {
+  display: flex;
+  align-items: center;
+  gap: var(--space-3);
+}
+
+.row-sm { gap: var(--space-2); }
+.row-md { gap: var(--space-3); }
+.row-lg { gap: var(--space-4); }
+
+.row.items-start { align-items: flex-start; }
+.row.items-center { align-items: center; }
+.row.items-end { align-items: flex-end; }
+
+.stack {
+  display: flex;
+  flex-direction: column;
+  gap: var(--space-3);
+}
+
+.stack-sm { gap: var(--space-2); }
+.stack-md { gap: var(--space-3); }
+.stack-lg { gap: var(--space-4); }
+.stack-xl { gap: var(--space-5); }
+
+.justify-between { justify-content: space-between; }
+.justify-center { justify-content: center; }
+.justify-end { justify-content: flex-end; }
+
+.flex-1 { flex: 1; }
+.flex-none { flex: none; }
+
+.w-full { width: 100%; }
+.min-w-0 { min-width: 0; }
+.max-w-prose { max-width: 65ch; }
+.max-w-form { max-width: 800px; }
+```
+
+### 6.2 Spacing utilities
+
+```css
+.m-0 { margin: 0; }
+.mt-1 { margin-top: var(--space-1); }
+.mt-2 { margin-top: var(--space-2); }
+.mt-3 { margin-top: var(--space-3); }
+.mt-4 { margin-top: var(--space-4); }
+.mt-5 { margin-top: var(--space-5); }

+
+.mb-0 { margin-bottom: 0; }
+.mb-1 { margin-bottom: var(--space-1); }
+.mb-2 { margin-bottom: var(--space-2); }
+.mb-3 { margin-bottom: var(--space-3); }
+.mb-4 { margin-bottom: var(--space-4); }
+.mb-5 { margin-bottom: var(--space-5); }
+.mb-6 { margin-bottom: var(--space-6); }
+
+.ml-auto { margin-left: auto; }
+.mr-auto { margin-right: auto; }
+
+.p-1 { padding: var(--space-1); }
+.p-2 { padding: var(--space-2); }
+.p-3 { padding: var(--space-3); }
+.p-4 { padding: var(--space-4); }
+.p-5 { padding: var(--space-5); }
+
+.px-2 { padding-left: var(--space-2); padding-right: var(--space-2); }
+.px-3 { padding-left: var(--space-3); padding-right: var(--space-3); }
+.px-4 { padding-left: var(--space-4); padding-right: var(--space-4); }
+
+.py-1 { padding-top: var(--space-1); padding-bottom: var(--space-1); }
+.py-2 { padding-top: var(--space-2); padding-bottom: var(--space-2); }
+.py-3 { padding-top: var(--space-3); padding-bottom: var(--space-3); }
+.py-4 { padding-top: var(--space-4); padding-bottom: var(--space-4); }
+```
+
+### 6.3 Typography utilities
+
+```css
+.text-xs { font-size: var(--font-size-xs); }
+.text-sm { font-size: var(--font-size-sm); }
+.text-base { font-size: var(--font-size-base); }
+.text-lg { font-size: var(--font-size-lg); }
+.text-xl { font-size: var(--font-size-xl); }
+
+.font-mono { font-family: "IBM Plex Mono", monospace; }
+.font-medium { font-weight: 500; }
+.font-semibold { font-weight: 600; }
+
+.text-center { text-align: center; }
+.text-left { text-align: left; }
+.text-right { text-align: right; }
+```
+
+### 6.4 Visual utilities
+
+```css
+.cursor-pointer { cursor: pointer; }
+.overflow-auto { overflow: auto; }
+.overflow-hidden { overflow: hidden; }
+
+.rounded-sm { border-radius: var(--radius-sm); }
+.rounded-md { border-radius: var(--radius-md); }
+.rounded-lg { border-radius: var(--radius-lg); }
+.rounded-xl { border-radius: var(--radius-xl); }
+.rounded-full { border-radius: var(--radius-full); }
+```
+
+### 6.5 Card utilities
+
+```css
+.card-sm {
+  padding: var(--space-3);
+  background: var(--panel);
+  border: 1px solid var(--border);
+  border-radius: var(--radius-md);
+}
+
+.card-md {
+  padding: var(--space-4);
+  background: var(--panel);
+  border: 1px solid var(--border);
+  border-radius: var(--radius-md);
+}
+
+.card-lg {
+  padding: var(--space-5);
+  background: var(--panel);
+  border: 1px solid var(--border);
+  border-radius: var(--radius-lg);
+}
+```
+
+Ensure existing `.card` rules remain backward-compatible.
+
+---
+
+## 7. Button Class Alignment
+
+The codebase uses many ad-hoc button class names: `.primary-button`, `.secondary-button`, `.ghost-button`, `.button-secondary`, `.delete-btn`.
+
+For Pass 2, align the most common ones to the new `.btn` primitives where feasible:
+
+- `.primary-button` → keep as alias to `.btn.btn-primary`
+- `.secondary-button` / `.button-secondary` → keep as alias to `.btn.btn-secondary`
+- `.ghost-button` → define explicitly or alias to `.btn.btn-secondary`
+- `.btn-icon` → add a modifier `.btn.btn-icon` for icon-only buttons
+
+Because renaming every caller is risky, the worker should:
+1. Add the aliases in CSS so both old and new class names work.
+2. Update only the refactored components to use the new `.btn*` classes.
+3. Leave other callers untouched to keep the diff focused.
+
+---
+
+## 8. Acceptance Criteria
+
+- [ ] All six target components have significantly fewer inline style blocks.
+- [ ] No hardcoded `280px` sidebar widths remain; `var(--sidebar-width)` is used.
+- [ ] New layout/spacing/typography/visual utilities from §6 are present.
+- [ ] `.form-group` and `.form-field` share a single rule block.
+- [ ] `.status-badge` family exists and is used by at least one caller.
+- [ ] Button aliases (`.primary-button`, `.secondary-button`, `.ghost-button`) map to `.btn` primitives.
+- [ ] `npm run typecheck` passes in `apps/web`.
+- [ ] `npm run lint` passes in `apps/web`.
+- [ ] No visual regressions in Tool Workshop and Config Profiles pages.
+
+---
+
+## 9. Verification Plan
+
+1. Run `cd apps/web && npm run typecheck`.
+2. Run `cd apps/web && npm run lint`.
+3. Count inline `style={{` blocks in the six target components before/after; expect ≥50% reduction overall.
+4. Search for `280px` in `apps/web/src`; expect zero matches (except in comments/docs).
+5. Open Tool Workshop and Config Profiles in browser/dev server and verify layout.
+6. Check that `.status-badge` renders correctly in at least one place.
+
+---
+
+## 10. Next Phase
+
+After this spec is approved, create **tasks** for Pass 2 implementation, then delegate to `sdd-apply`.

+| `npm run build` | ✅ Pass (only pre-existing chunk-size warnings) |
+| Inline `style={{` reduction | ✅ 198 → 11 (94% reduction, target was ≥50%) |
+| Hardcoded `280px` sidebar widths | ✅ Removed from sidebars; token `--sidebar-width` used |
+| `.status-badge` defined and used | ✅ Defined in global.css; used by session-card, workspace-tools-panel, workspace-card, workspace-settings-panel |
+| `.form-group`/`.form-field` unified | ✅ Both selectors share one rule block |
+
+### Inline Style Counts
+
+| Component | Before | After |
+|---|---|---|
+| `manifest-editor.tsx` | 70 | 7 |
+| `ConfigProfileEditorPanel.tsx` | 51 | 2 |
+| `ToolTypeEditorPanel.tsx` | 20 | 0 |
+| `ToolTypeListSidebar.tsx` | 12 | 0 |
+| `ConfigProfileListSidebar.tsx` | 14 | 0 |
+| `git-mount-editor.tsx` | 31 | 2 |
+| **Total** | **198** | **11** |
+
+## Remaining Inline Styles (intentionally kept)
+
+- `manifest-editor.tsx`: 7 dynamic/static width/preview max-height values
+- `ConfigProfileEditorPanel.tsx`: 1 select width, 1 preview max-height
+- `git-mount-editor.tsx`: 1 disabled-state opacity/pointer-events block, 1 warning color span
+
+These were kept because they represent dynamic computed values or one-off sizes that do not map cleanly to a reusable token class without adding overly specific utilities.
+
+## Risks / Open Questions
+
+- The refactor removed some hover background color manipulation via `onMouseEnter`/`onMouseLeave` in the sidebars in favor of CSS `:hover`. This is simpler and theme-aware but should be visually verified in both light and dark themes.
+- Some legacy class names (`.primary-button`, `.secondary-button`, `.ghost-button`, `.button-secondary`, `.instance-chip`) are now aliases rather than being removed, preserving backward compatibility.
+- Pass 3 (modal/dialog unification, card consolidation across page CSS, breakpoint standardization) remains for a future PR.
