What it can do on your machine

Read from SKILL.md and the folder at commit 6522504. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(python:*)
    • WebFetch

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    From compatibility in the SKILL.md frontmatter.

Context cost

Israeli Grocery Price Intelligence loads about 2.3k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 151 tokens; SKILL.md has 1,109 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~151
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Israeli Grocery Price Intelligence

Instructions

Step 1: Access Supermarket XML Feeds

Under the 2015 Price Transparency Law (חוק שקיפות מחירים), Israeli supermarket chains with 3+ stores must publish product prices as XML files.

  • Data published at: prices.shufersal.co.il, and similar portals per chain
  • Available data files:
    • PricesFull — complete product catalog with prices
    • PricesPromotions — current sales and promotions
    • Stores — store locations and details
  • Files updated daily (typically overnight)
  • See references/chain-feeds.md for per-chain URLs and access methods
Step 2: Parse Chain-Specific Data Formats

Each chain publishes in a slightly different XML schema. Supported chains and their format:

ChainHebrew NameFeed URL PatternNotes
Shufersalשופרסלprices.shufersal.co.ilLargest chain, most structured data
Rami Levyרמי לויprices.rframi.co.ilKnown for low prices
YochananofיוחננוףSee references/chain-feeds.mdCentral Israel focus
Victoryויקטוריprices.victory.co.ilPublicly traded, separate from Carrefour Israel
Carrefour Israel (formerly Mega/Yeinot Bitan)קרפור ישראלprices.mega.co.ilRebranded from Mega/Yeinot Bitan in 2022-2023
Osher Adאושר עדprices.osherad.co.ilDiscount chain
Tiv Taamטיב טעםprices.tivtaam.co.ilNon-kosher items available

Use scripts/parse_price_xml.py to parse feeds into normalized JSON format. Key fields: item_code, item_name, manufacturer, price, unit_price, quantity, unit_of_measure, update_date

Step 3: Cross-Chain Price Comparison

Match products across chains by:

  • Barcode (most reliable — Israeli standard barcode)
  • Item name + manufacturer (fuzzy matching for naming differences)
  • Item code (chain-specific, less reliable for cross-chain)

Generate comparison table for specific products:

  • Calculate: cheapest chain, average price, price spread (max-min)
  • Handle store-specific pricing (same chain may have different prices by location)
Step 4: Optimize Shopping Lists

Given a shopping list, find the cheapest option:

  • Single-store: cheapest store for entire basket
  • Multi-store: optimal split across 2-3 nearby stores (minimize cost + travel)

Factor in current promotions (PricesPromotions feed). Handle substitutions: suggest cheaper alternatives for similar products.

Calculate total basket cost per scenario. Consider user preferences: kosher requirements, organic options, brand preferences.

Monitor prices over time for tracked products:

  • Alert on significant changes (>10% increase or decrease)
  • Weekly price trend report for tracked categories
  • Track inflation patterns by food category
  • Compare against CPI food component data
Step 6: Restaurant/Catering Ingredient Cost Analysis

For restaurant owners: calculate ingredient costs from supermarket data.

  • Input: recipe with ingredients and quantities
  • Output: cost per serving based on cheapest available prices
  • Track ingredient cost trends over time
  • Alert when key ingredient prices spike
  • Generate monthly cost report for menu pricing decisions

Examples

Example 1: Compare Milk Prices Across Chains

User says: "What's the cheapest place to buy Tnuva 3% milk 1 liter?" Actions:

  1. Query PricesFull feeds from all chains for item (barcode matching)
  2. Compile prices per chain and store location
  3. Apply any active promotions from PricesPromotions
  4. Generate comparison table sorted by price Result: Cheapest: Rami Levy at 5.90 NIS, Osher Ad at 6.10 NIS, Shufersal at 6.50 NIS (but 2-for-10 promo active). With Shufersal promo, buying 2 = 5.00 NIS each. Recommendation: Shufersal if buying 2+, Rami Levy for single.
Example 2: Optimize Weekly Shopping List

User says: "Here's my shopping list for the week, find me the cheapest option near Ramat Gan" Actions:

  1. Parse shopping list (15 items)
  2. Find prices at chains with stores near Ramat Gan
  3. Calculate: single-store (Rami Levy: 285 NIS, Shufersal: 310 NIS, Yochananof: 295 NIS)
  4. Calculate: optimal 2-store split (Rami Levy + Shufersal with promos: 262 NIS)
  5. Suggest 3 substitutions saving additional 18 NIS Result: Best single-store: Rami Levy at 285 NIS. Optimal split: Rami Levy (10 items, 195 NIS) + Shufersal (5 items with promos, 67 NIS) = 262 NIS. Total savings vs single-store: 23 NIS.
Example 3: Track Ingredient Costs for Restaurant Menu

User says: "Track the cost of ingredients for my shakshuka dish — tomatoes, eggs, onions, peppers, spices" Actions:

  1. Identify matching products in price feeds (fresh tomatoes, eggs size L, yellow onions, bell peppers, cumin, paprika)
  2. Find cheapest per ingredient across chains
  3. Calculate cost per serving (2 eggs, 3 tomatoes, 1 onion, 1 pepper, spices)
  4. Set up weekly price monitoring for these ingredients
  5. Generate baseline cost report Result: Current cost per serving: 8.40 NIS (cheapest chain combination). Eggs are 32% of cost. Price alert configured — you'll be notified if any ingredient price changes >10%.

Bundled Resources

References
  • references/chain-feeds.md — URLs and access methods for each Israeli supermarket chain's price transparency feeds. Includes XML schema documentation, update schedules, and known format variations. Consult when accessing chain data in Steps 1-2.
Scripts
  • scripts/parse_price_xml.py — Parses Israeli supermarket XML price feeds into normalized JSON. Supports Shufersal, Rami Levy, and other chain formats. Handles gzipped XML files and character encoding. Run: python scripts/parse_price_xml.py --help

Gotchas

  • Israeli supermarket chain URLs and XML feed schemas change without notice. Agents relying on cached or training-data URLs will hit broken endpoints. Always verify feed URLs from references/chain-feeds.md before querying.
  • Prices in Israel include VAT (18%) by default, unlike US prices which are pre-tax. Agents may perform cost comparisons that double-count or ignore VAT depending on their training data assumptions.
  • Israeli product barcodes use the 729 country prefix, but some imported products retain their original country barcode. Agents may fail cross-chain matching when the same product has different barcode formats across chains.
  • "Mega" and "Yeinot Bitan" rebranded to Carrefour Israel in 2022-2023. "Victory" is a separate publicly traded company. Agents may still refer to the outdated "Victory / Mega" grouping or assume they share pricing policies.
  • Promotions in Israeli supermarkets often have conditions agents miss: "buy 2 get discount" (2 b-X shekel), club-member-only pricing, or regional promotions that apply only to specific store locations.

Troubleshooting

Error: "XML feed download failed"

Cause: Chain's price transparency server is temporarily down or URL has changed. Solution: Check if the chain updated their feed URL (this happens occasionally). Try accessing the feed manually in a browser. Feeds are typically most reliable in the morning hours (updated overnight). See references/chain-feeds.md for current URLs.

Error: "Product not found in cross-chain comparison"

Cause: Product naming or barcode differs across chains. Solution: Try matching by barcode first (most reliable). If barcode match fails, use fuzzy name matching with manufacturer. Some chains use different product names for the same item (e.g., "חלב תנובה 3%" vs "חלב 3% תנובה").

Error: "Price data outdated"

Cause: Using cached data from a previous day or the chain hasn't updated yet. Solution: Check the UpdateDate field in the XML feed. Most chains update overnight. If data is >24 hours old, force a fresh download. Promotions feed updates may lag behind PricesFull updates.

Error: "Shopping list optimization slow"

Cause: Comparing all items across all chains and all stores is computationally expensive. Solution: Limit comparison to chains with stores within a configurable radius (default: 5 km). Pre-filter by chains the user actually shops at. Use cached price data instead of fetching fresh for every optimization.
