⏺ Now I'll invoke the ralph-task-setup skill to gather requirements for this receipt upload UI feature.
⏺ /ralph-task-setup
⏺ I'll set up the Ralph task for the receipt upload UI feature. Let me first explore the existing codebase to ask informed questions.
⏺ Search(pattern: "src/**/*expense*.{ts,tsx}")
⎿  Found 2 files (ctrl+o to expand)
⏺ Search(pattern: "supabase/migrations/*.sql")
⎿  Found 3 files (ctrl+o to expand)
⏺ Search(pattern: "src/components/ui/*.tsx")
⎿  Found 15 files (ctrl+o to expand)
⏺ Read(src/components/expenses/expense-form.tsx)
⎿  Read 227 lines
⏺ Read(supabase/migrations/20260118000001_storage_setup.sql)

⎿  Read 221 lines
⏺ Search(pattern: "src/app/**/expenses/**/*.tsx")
⎿  Found 3 files (ctrl+o to expand)
⏺ I now have a good picture of the codebase. The foundation is in place:
- Database: receipt_path and receipt_status fields already exist on expenses
- Storage: receipts bucket configured with user-scoped RLS policies
- Hooks: Already support filtering by receiptStatus
- Form: Current ExpenseForm has no receipt upload functionality yet
---
Phase 1: Requirements Interview
Let me confirm the Jobs to Be Done and ask a few clarifying questions.
Proposed JTBD (from issue #4):
1. Upload receipts - Users can attach receipt images/PDFs when creating or editing expenses
2. Preview receipts - Users can view receipts before saving and after attachment
3. Manage receipts - Users can remove or replace attached receipts
4. Track receipt status - Users can see at a glance which expenses have receipts
---
Question 1: Upload Flow
The issue mentions "drag-and-drop and click-to-upload" plus "camera capture should be prominent on mobile."
⏺ User answered Claude's questions:
⎿  · Should the upload happen immediately when a file is selected, or only
when the expense form is submitted? → Immediate upload
⏺ Immediate upload - upload starts as soon as file is selected.
This means:
- Upload goes to storage immediately with progress indicator
- Expense save just stores the receipt_path reference
- Need to handle orphaned files if user abandons form (or accept they exist)
---
Question 2: File Constraints
⏺ User answered Claude's questions:
⎿  · What's the maximum file size for receipts? → 5 MB (Recommended)
⏺ 5 MB max - reasonable for most receipts.
---
Question 3: Image Compression
⏺ User answered Claude's questions:
⎿  · Should images be compressed client-side before upload? → No
compression
⏺ No compression - simpler implementation, upload originals.
---
Question 4: Receipt Viewing
⏺ User answered Claude's questions:
⎿  · How should users view attached receipts? → Modal/lightbox overlay
⏺ Modal/lightbox - click thumbnail opens full-size view in-app.
---
Question 5: Orphaned Files
Since uploads happen immediately, if a user uploads a receipt but then cancels or navigates away, that file stays in storage.
⏺ User answered Claude's questions:
⎿  · How should orphaned receipt files (uploaded but never linked to an
expense) be handled? → Accept orphans (Recommended)
⏺ Accept orphans - simplifies MVP. Can add cleanup job later.
---
Confirmed Jobs to Be Done
1. JTBD-1: Upload receipts - Users can attach receipt images/PDFs (JPEG, PNG, PDF) up to 5MB when creating or editing expenses, with immediate upload and progress feedback
2. JTBD-2: Preview receipts - Users can see thumbnail previews during upload and view full-size receipts in a lightbox modal
3. JTBD-3: Manage receipts - Users can remove or replace attached receipts on existing expenses
4. JTBD-4: Track receipt status - Users can see receipt status indicators (none/pending/attached) in the expense list

Topics of Concern (Decomposed)
Based on the JTBD, here are the distinct topics (each passes the one-sentence test):
| # | Topic | Description |
|-----|-----------------------------|----------------------------------------------------------------------------------------------------------------------------------------------|
| 1 | Receipt Upload Component | A reusable component that handles file selection (drag-drop, click, mobile camera) and immediate upload to Supabase storage with progress UI |
| 2 | Receipt Preview & Lightbox | Display thumbnail previews for images, PDF icons for documents, and full-size modal viewing |
| 3 | Expense Form Integration | Integrate upload component into ExpenseForm for create and edit modes |
| 4 | Receipt Management Hooks | TanStack Query hooks for uploading, deleting, and fetching receipts from Supabase storage |
| 5 | Expense List Receipt Status | Show receipt status badge/icon on each expense row in the list view |
---
Does this breakdown look correct before I generate the spec files?
⏺ User answered Claude's questions:
⎿  · Does this JTBD and topic breakdown look complete? Anything to add or
remove? → it looks good, lets add an orphaned reciepts view, just that
for now (working with those reciepts will be a later feature out of
scope)
⏺ Added Topic 6: Orphaned Receipts View - a read-only view showing receipts that exist in storage but aren't linked to any expense (management deferred to later).
---
Final Topics
| # | Topic | Description |
|-----|-----------------------------|----------------------------------------------------------------------------------------|
| 1 | Receipt Upload Component | File selection (drag-drop, click, mobile camera) with immediate upload and progress UI |
| 2 | Receipt Preview & Lightbox | Thumbnail previews and full-size modal viewing |
| 3 | Expense Form Integration | Integrate upload into create/edit expense forms |
| 4 | Receipt Management Hooks | TanStack Query hooks for upload, delete, fetch operations |
| 5 | Expense List Receipt Status | Receipt status badge/icon on expense list rows |
| 6 | Orphaned Receipts View | Read-only page listing unlinked receipts (no management actions) |
Now I'll generate the spec files. First, let me check if the Ralph resources already exist:
⏺ Bash(ls -la /Users/sam/Projects/revenue-experiments/expenses-sbucks/specs/
2>/dev/null || echo "No specs dir"; ls -la
/Users/sam/Projects/revenue-experiments/expense…)

# Receipt Upload UI - Product Requirements Document
## Overview
Implement a receipt upload feature allowing users to attach images and
PDFs to expenses. This includes drag-and-drop upload, thumbnail
previews, lightbox viewing, and receipt status tracking in the expense
list. Additionally, provide a read-only view of orphaned receipts
(uploaded but not linked to expenses).

(JPEG, PNG, PDF) up to 5MB when creating or editing expenses, with
immediate upload and progress feedback
2. **JTBD-2: Preview receipts** - Users can see thumbnail previews
during upload and view full-size receipts in a lightbox modal

# Agent Context
## Task Summary
Add receipt upload functionality to the expense tracking app. Users can
attach JPEG, PNG, or PDF receipts (max 5MB) to expenses with immediate
upload, preview thumbnails, lightbox viewing, and status indicators in
the expense list. Also add a read-only orphaned receipts view.
## Key Decisions
- **Immediate upload**: Files upload to Supabase storage as soon as
selected, not on form submit
- **No compression**: Upload original files as-is (max 5MB limit
handles size)

# Building Loop Prompt
You are an implementation agent executing the building phase of the
Ralph Wiggum methodology.
## Phase 0: Identify Task
**First**, read `.ralph-task` to get the spec directory path. This
file contains the path like `specs/receipt-upload-ui`.
If `.ralph-task` doesn't exist, scan `specs/` for directories
containing `IMPLEMENTATION_PLAN.md` and use the first one with
unchecked tasks.

Recommendations:
- Run in sandboxed environment (Docker recommended)
- Start with default 15 iterations
- Monitor for "STUCK:" markers in output
- "Sit on the loop, not in it" - observe but don't intervene unless needed
