  Use this skill when extracting product names from Hebrew building material delivery
  notes (תעודות משלוח) or invoices — whether from an uploaded image, PDF, or typed-out
  invoice text. Trigger on: any delivery note or invoice upload, "read this invoice",
  "what products are here", "extract materials from this", "check these materials",
  "what's on this delivery note", or any request to identify building material products
  from a document. This skill is essential for accurate extraction — without it Claude
  tends to drop Hebrew prepositions, confuse similar-looking letters, and mix model
  numbers across brands. ALWAYS use it when a delivery note or materials list is involved.

# Hebrew Building Materials Invoice Reader

## Your Task

Extract ONLY product names from the delivery note (תעודת משלוח). Return a JSON array of strings — nothing else.

Each string = one product name, written exactly as it appears in the document, including model codes and grade designations.

## Handling Rotated or Upside-Down Scans

Many real delivery notes are photographed or scanned upside down. If text appears mirrored or inverted:
- Rotate mentally and still extract the products
- The supplier logo/letterhead usually appears at the top — use it to orient yourself
- Common upside-down senders: SAKRET Israel (green checkmark logo), LYMA (dark logo)
- If in doubt, look for recognizable brand names (כוחלה, SAKRET, TAMCRETE, VALSIR) regardless of orientation

## Invoice Column Structure

Israeli delivery notes almost always have a table. The **תיאור** (description) column is what you extract from. Ignore all other columns:

| Column | Hebrew name | Extract? |
|---|---|---|
| Item # | #, מס' | ❌ |
| Asset / SKU | אסמ', מק"ט, קוד פריט | ❌ |
| **Description** | **תיאור, תיאור מוצר** | **✅ YES** |
| Unit | יח', ניר | ❌ |
| Quantity | כמות | ❌ |
| Price | מחיר, סה"כ, ₪ | ❌ |

If there is no table (free-form note), extract lines that start with a product name.

## What to Include

- Product / material names (שם מוצר)
- Model codes and grade specifications (e.g., FL810, AD 700, PR-007, C2TES2, MC1)
- Descriptive suffixes that are part of the product name (e.g., "עמיד אש", "עמיד במים", "EXTRA WHITE")
- **Tile dimensions** when they are part of the product identity: `120*120`, `80*180*2`, `180*23*0.65`
- **Pipe sizes** when part of the product name: `3/8"`, `1/2"`, `110mm`
- Color/variant codes for tiles and flooring: `גוון 1010`, `כרמית`, `GREY`, `A3555 HH`

## What to Exclude

- Quantities and units (כמות, ק"ג, ליטר, מ"ר, יח', שק, דלי, ניר)
- Prices and totals (מחיר, סה"כ, ₪, מחיר יחידה)
- Catalog / SKU numbers (מק"ט, ברקוד, אסמ', קוד פריט, VS03..., PO23...) — unless the SKU IS recognizable as the product name
- Customer name, address, phone, company header
- Column headers ("שם מוצר", "כמות", "מחיר", "תיאור" etc.)
- Dates and document numbers
- Lot numbers / shade codes that appear AFTER the product name (e.g., the `672 69-315` in `TAMCRETE MC1 672 69-315` — include only `TAMCRETE MC1`)
- `שק 25 ק"ג` — always packaging, always exclude

## Hebrew Letter Disambiguation

When reading from photos, scans, or handwriting, take extra care with these confusable pairs:

| Confused pair | Key visual tell | Typical in context |
|---|---|---|
| **ב** (bet) vs **כ** (kaf) | כ has a more open downward curve; ב is rounder | "עמיד **ב**מים" — the ב here is crucial |
| **ד** (dalet) vs **ר** (resh) | ד has a sharper 90° top-right corner; ר is rounded | "לוח **ג**בס" — גבס not גרס |
| **ה** (he) vs **ח** (khet) vs **ת** (tav) | ה has a gap at top-right; ח is closed all around; ת has small feet | "**ח**סין אש" (not הסין) |
| **ו** (vav) vs **ז** (zayin) | ז has a horizontal top stroke; ו is just a vertical line | common in word-medial position |
| **נ** sofit (ן) vs **כ** sofit (ך) | ן descends in a straight line; ך has a slight curve | "תקן", not "תקך" |
| **מ** (mem) vs **ס** (samekh) | מ has an open bottom-right gap; ס is fully enclosed | "**מ**ים" vs "**ס**לע" |

If you read something that produces a nonsense Hebrew word, try the confusable letter.

## Latin Letter and Digit Disambiguation

| Characters | Rule of thumb | Example |
|---|---|---|
| **O** vs **0** | Letter O inside brand names; digit 0 in numeric strings | "OC200" — first char is letter O |
| **l** vs **1** vs **I** | Digit 1 in numeric codes; letter L in model names | "FL810" — L is a letter, 810 are digits |
| **B** vs **8** | Usually letter B following other letters | "TRBR-3/8" not "TR8R-3/8" |
| **S** vs **5** | Letter S at start of brand names | "SIKA", not "5IKA" |
| **G** vs **6** | Letter G in brand names | "GREY" not "6REY" |

## Preposition Rule — Critical

Hebrew prepositions **ב / ל / מ / כ / ש** attach directly to the next word with NO space. Do NOT drop them or split them off incorrectly.

| Attached form | Meaning | Full phrase |
|---|---|---|
| **במים** | in water | "עמיד **במים**" — NOT "עמיד מים" |
| **לריצוף** | for tiling | "דבק **לריצוף**" |
| **לצביעה** | for painting | "בסיס **לצביעה**" |

The difference between "עמיד במים" and "עמיד מים" matters for database matching.

## Product Code Pattern Reference

| Letters + digits (no space) | FL810, AD700, OC200, MC1 | Keep exactly as written |
| Letters + dash + digits | PR-007, AD-505, TRBR-3/8 | Preserve the dash |

| Tile dimensions | 120*120, 80*180*2, 180*23*0.65 | Part of product identity |
| Tile quality grades | C2TES2, C1T, S1, A3555 HH | EU/ISO designations — keep as-is |

## Real Invoice Examples

From actual delivery notes seen in the field:

**כוחלה invoice (אחד לבנין):**
- Full description: `כוחלה 119 לבן גוון 1010 שק 25 ק"ג כרמית`
- Extract as: `כוחלה 119 לבן`
- Why: "גוון 1010 כרמית" is color specification; "שק 25 ק"ג" is packaging

**SAKRET/TAMCRETE invoice:**
- Full description: `TAMCRETE MC1 672 שלדה 69-315`
- Extract as: `TAMCRETE MC1`
- Why: "672" and "69-315" are lot/shade numbers, not part of the product name

**LYMA tile invoice:**
- Full description: `MOTIF 120G 120*120 נ"ק`
- Extract as: `MOTIF 120G 120*120`
- Why: dimensions are part of the tile identity; `נ"ק` (nominal quality) is a classification tag — exclude it

**VALSIR plumbing invoice (מנדלסון):**
- Full description: `VALSIR 110 45 זית`
- Extract as: `VALSIR 110 45 זית`
- Why: 110 is pipe diameter, 45 is angle (elbow type), זית (olive/elbow) is the fitting type — all part of the product name

**C2TES2 adhesive:**
- Full description: `C2TES2 - 35 861 דבק אריחים`
- Extract as: `C2TES2 דבק אריחים` (or just `C2TES2`)
- Why: "35" and "861" are internal codes; C2TES2 is the EU adhesive grade
