+# Phase 31: Mobile Polish - Context
+
+**Gathered:** 2026-04-12
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Replace text-based action buttons with icon buttons on mobile across all detail pages. This is a focused UI polish phase — no new features, just better mobile touch UX.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Icon Actions Scope
+- **D-01:** Apply icon-based action buttons on mobile to **all detail pages**: item detail, candidate detail, setup detail, catalog detail — anywhere action buttons appear.
+- **D-02:** Desktop keeps text buttons. Mobile (below sm: breakpoint) switches to icons. Uses the same responsive breakpoint as BottomTabBar.
+- **D-03:** Standard icon mapping: pencil/edit for Edit, trash for Delete, copy for Duplicate, share for Share (if applicable).
+
+### Mobile UX
+- **D-04:** No other specific mobile UX issues to address — user is happy with current mobile support beyond the icon buttons.
+
+### Claude's Discretion
+- Whether to add long-press tooltips on icon buttons for discoverability
+- Exact breakpoint for icon/text switch (likely `sm:` matching BottomTabBar)
+- Icon sizing and spacing for comfortable touch targets (minimum 44px)
+- Whether to use Lucide icons (already in project) or keep inline SVGs
+- Any additional small polish items noticed during implementation (tap target sizes, etc.)
+
+</decisions>
+
+<canonical_refs>
+## Canonical References
+
+**Downstream agents MUST read these before planning or implementing.**
+
+### Action Buttons (need icon variants)
+- `src/client/routes/items/$itemId.tsx` — Item detail actions: Duplicate, Delete/Remove, Edit (lines ~186-210)
+- `src/client/routes/threads/$threadId/candidates/$candidateId.tsx` — Candidate detail actions
+- `src/client/routes/setups/$setupId.tsx` — Setup detail actions (if any)
+- `src/client/routes/global-items/$globalItemId.tsx` — Catalog detail actions (if any)
+
+### Responsive Patterns
+- `src/client/components/BottomTabBar.tsx` — Mobile bottom nav, uses `md:hidden` breakpoint
+- `src/client/components/TopNav.tsx` — Desktop top nav, uses `hidden md:flex` breakpoint
+
+### Icon System
+- `src/client/lib/iconData.ts` — LucideIcon component, 119 curated icons
+
+</canonical_refs>
+
+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `LucideIcon` component — renders Lucide icons by name. Already used throughout the app.
+- BottomTabBar responsive pattern — `md:hidden` / `hidden md:flex` for mobile/desktop switch.
+- Tailwind responsive classes already established throughout the codebase.
+
+### Established Patterns
+- Mobile/desktop responsive switch at `md:` breakpoint (768px) — consistent with BottomTabBar and TopNav.
+- Action buttons are inline `<button>` elements with text — straightforward to add responsive icon variants.
+
+### Integration Points
+- Each detail page's action button section — wrap in responsive containers showing icons on mobile, text on desktop.
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- This is a small, focused phase. The user is generally happy with mobile support — just the text buttons on detail pages are the pain point.
+- Keep it simple — responsive icon/text swap using existing Tailwind breakpoints and LucideIcon.
