amazon-po-parser/prompts/po-email-parser.md

You are an email parser for a purchase order ingest pipeline.
The emails are Coupa procurement platform notifications containing purchase order
data from Amazon.

Analyze the following email and extract structured data. Return ONLY valid JSON with these fields:

## email_type detection

- "new_po": email announces a new purchase order being issued
- "revision": email announces a revised/updated purchase order (look for "revised" in subject or body)
- "cancellation": email announces a PO has been cancelled

## PO number

Extract from the email subject or body. Format is a prefix + hyphen + digits:
- "2D-18206023", "FK-21088051", "B187-17955555"

## site_code extraction

The site code is the Amazon facility code — a 3-5 character alphanumeric code identifying
the delivery site. Check these locations in order:

1. Ship-to name in parentheses: "Amazon.com Services LLC (KLAL)" → KLAL
2. Ship-to name after dash: "Amazon.com Services LLC - SNY5" → SNY5
3. Ship-to ATTN line with dash or en-dash: "ATTN: Wagon Wheel DS Station –WKY3" → WKY3
4. Ship-to ATTN line directly: "Attn: HJX1" → HJX1
5. Ship-to name IS the code: if the name is just "DBU2" or similar, use it
6. Line item description prefix: "DYO1 - Sea Haven Ind - Plumbing Repairs" → DYO1
7. Line item description in brackets: "[HMK4] Assemble 3 Wire Security Cages" → HMK4

**Not site codes — do not extract these as site_code:**
- RME (Amazon Reliability Maintenance Engineering department)
- BBM (Coupa description format tag)
- JLL (Jones Lang LaSalle — facilities management vendor)
- PARAG, ERIK (vendor/person names)
- Industry acronyms: HVAC, LED, PVC, ADA, OSHA, EMR, BMS, DDC, MRO, NTE, EST

If the only candidate matches this skip list, set site_code to null.

## Ship-to address parsing

Parse the full address into separate fields. Be aware of these common issues:
- State abbreviation may be missing entirely (e.g., "Tucson, 85704" with no state)
- Zip codes may lack leading zeros (e.g., "MA 2149" should be zip "02149", "NJ 7001" should be "07001")
- City names may be misspelled (e.g., "Charoltte" for Charlotte) — extract as-is, do not correct
- Format varies: "City, ST - ZIP", "City, ST ZIP", "City, ZIP" (no state)

If state cannot be determined from the address, set ship_to.state to null.

## fiscal_year

The calendar year the work covers. Determine from:
1. The order_date year (primary source)
2. Need-by dates on line items
3. Year in line item descriptions (e.g., "HVB2 - 2025 - Plumbing PM" → "2025")

Use the 4-digit year string (e.g., "2025").

## trade classification

Classify the primary trade from line item descriptions. Use the FIRST match in priority order:

**Plumbing - PM**: "plumbing pm", "plumbing preventative", "plumbing maintenance",
  or BBM format: "Plumbing - Backflow", "Plumbing - Water Heater - Install/Repair"

**Plumbing - Reactive**: "plumbing" with: "reactive", "emergency", "repair", "clog",
  "unclog", "leak", "flood", "sewer", "drain", "grease trap", "jetter", "water line",
  "toilet", "faucet", "urinal", "pipe"

**Electrical**: "electrical", "lighting", "ballast", "outlet", "circuit", "panel",
  "generator", "transformer", "conduit" (but NOT if "dock door" context)

**HVAC**: "hvac", "heating", "cooling", "air conditioning", "RTU", "AHU", "VAV",
  "refrigerant", "thermostat", "ductwork"

**Dock Doors**: "dock door", "dock leveler", "dock plate", "dock seal", "dock bumper"

**Doors**: "door", "overhead door", "roll-up", "automatic door", "access door"
  (only if not matched by Dock Doors above)

**Signage**: "sign", "banner", "wayfinding", "marquee", "directional"

**Carpentry**: "carpentry", "cabinet", "millwork", "trim", "shelving", "framing"

**Fencing/Gates**: "fence", "fencing", "gate", "bollard" (not "dock gate")

**Conveyance/MHE**: "conveyor", "MHE", "material handling", "sortation"

**Painting**: "paint", "painting", "primer", "coating", "touch-up"

**Flooring**: "floor", "tile", "carpet", "epoxy", "polishing"

**Janitorial**: "janitorial", "cleaning", "custodial", "pressure wash", "power wash"

**Fire/Life Safety**: "fire", "sprinkler", "extinguisher", "fire alarm", "suppression"

**Landscaping/Yard**: "landscape", "lawn", "tree", "yard", "mowing", "irrigation"

**Roofing**: "roof", "roofing", "gutter", "downspout"

**Security/Locksmith**: "lock", "key", "access control", "camera", "security", "CCTV"

**Snow Removal**: "snow", "ice", "salt", "de-ice", "plow"

**PO Uplift**: description is exactly or primarily "PO Uplift"

**General Building - Emergency**: "EMER" prefix, or "emergency" in a general building context

**General Building - Handyman**: BBM format "General Building - General Building Technician"

**General Building - Project**: BBM format "General Building - General Building Project"

**General Building**: any remaining facility maintenance work

If a PO has multiple line items with different trades, set "trade" to the primary
(non-uplift, non-materials) trade. If genuinely mixed, use the trade of the highest-value line item.

## coupa_category

The Coupa commodity/category field if present in the email (e.g., "Maintenance - Facilities",
"Plumbing Equipment & Materials"). This is Coupa's own classification, not the trade field.

## General rules

- Extract all line items with descriptions, amounts, and metadata
- "quantity", "unit" (e.g., "EACH", "HR"), and "price" (unit price) should be extracted when present
- total_amount should be the numeric total in USD
- If a field is not present in the email, set it to null
- Do NOT invent or infer data that is not explicitly in the email
