Claude Code: ask. ### `filter_vehicles` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Preferred structured inventory lookup when make/model/year/color/location are known. Exact hard filters only via GET /v1/vehicles (same Meilisearch collection as search_vehicles). Totals match the filters you pass. Shop inventory includes listings without photos, so the same filters return the same total here and on Shop. fuelType is the canonical label. transmission and drivetrain match every indexed raw string in that bucket (automatic includes "8-Speed Automatic"). A 503 powertrain_filter_unavailable means that facet list could not be read, not that zero cars match. Resolve make/model with list_research_makes / list_research_models first. Map shopper prose onto labeled keys; use search_vehicles only for fuzzy NL or VIN-in-q lookup. Often the first step in shopping playbooks (budget_coach, safety_first, price_drop_sniper, dealer_crawl). After results, chain get_deal_score / get_vehicle_history / check_recalls / compare_vehicles when the user needs a recommendation, not just a list. See opendealer://assistant/shopping-playbooks. CRITICAL: CITE: Each vehicle's cite object is `vin` + `url` (canonical opendealer.shop VDP). Cite only `url` to shoppers. Never invent VDP URLs. Never cite `detailsUrl` (dealer/LotLinx). Never send shoppers to `/llm/*` HTML or `/v1/llm/*` as the human listing URL. ``` ## Only reads (24) Looks things up and changes nothing. Claude Code: allow. ### `check_recalls` - The description's first verb is "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Get NHTSA open safety recalls for a vehicle by VIN. Returns recall campaigns resolved at the year/make/model level (YMM-granular). A recall listed for the model year may not apply to every VIN — the response includes NHTSA's disclaimer and campaign details (component, summary, remedy status, Park It / Park Outside advisories). Use this when a shopper asks about recalls, safety campaigns, or whether a specific model has open NHTSA notices. Required step in vehicle_dossier and safety_first playbooks; always include the YMM-granularity disclaimer. ``` ### `compare_market` - The name "compare_market" says "compare": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Compare pricing across market segments. Provide cohortKeys or make (optionally with model). ``` ### `compare_models` - The name "compare_models" says "compare": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Provide composite make-model slugs like "honda-civic" or "toyota-corolla". Returns: • Winner-by-dimension deltas: price, fuel economy, horsepower, seating, towing, NHTSA safety, live median listing price • Full research payload for each model (trims, MSRPs, specs) Use this for "Civic vs Corolla" style questions. To compare specific listed vehicles by VIN, use compare_vehicles instead. CRITICAL: Only use the 'url' field from the response for links. NEVER invent or construct URLs. ``` ### `compare_vehicles` - The name "compare_vehicles" says "compare": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Compare 2-5 vehicles side by side. Returns a structured comparison including specs, price context, and per-vehicle cite fields (vin + shop url). CRITICAL: CITE: Each vehicle's cite object is `vin` + `url` (canonical opendealer.shop VDP). Cite only `url` to shoppers. Never invent VDP URLs. Never cite `detailsUrl` (dealer/LotLinx). Never send shoppers to `/llm/*` HTML or `/v1/llm/*` as the human listing URL. ``` ### `dealer_inventory` - The description's first verb is "browse": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "browse": it reads web pages, which anyone can write. Description, as the server wrote it: ```untrusted-server-text Browse the complete inventory of a specific dealership. IMPORTANT: Use the exact dealer slug from a previous dealers_near or search_vehicles response. Do NOT guess dealer IDs. Useful when a user wants to see what a particular dealer has in stock.

Prefer a slug from dealers_near or search results. A display name binds only when it matches one rooftop. Shared names (two Jay Hatfield stores, or just "Honda") return candidate slugs instead of picking one. CRITICAL: Only use URL fields from the response (website, urls.*). NEVER invent or construct URLs. ``` ### `get_market_overview` - The name "get_market_overview" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Answers questions like "is a 2023 RAV4 safe for my family" with: • Overall and crash-test star ratings (when published) • Rollover rating / possibility • NHTSA-evaluated ADAS availability (ESC, FCW, LDW) Ratings are model-year granular from the NHTSA NCAP cache. If no confident rating exists, the tool reports that honestly rather than guessing. For VIN-specific listing details use get_vehicle; for open recalls use check_recalls.

NEVER invent URLs. ``` ### `get_similar_vehicles` - The name "get_similar_vehicles" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it: ```untrusted-server-text Forgiving vehicle search (Meilisearch): natural-language q, typo-tolerant make/model/color, optional structured filters. Use when the shopper query is fuzzy or exploratory. Use filter_vehicles instead when make/model/year/body/price/location are known — it applies exact hard filters via GET /v1/vehicles and returns trustworthy totals. Discovery order: list_facets / list_research_makes → filter_vehicles (structured) or search_vehicles (exploratory) → get_vehicle / get_deal_score for depth. Location (choose ONE): zip+radius, lat+lng+radius, city+state+radius, county+state+radius — or embed location in q. q may also be a 17-character VIN for exact lookup. When the ask implies analysis (deal, safety, budget, timing, dealer plan), chain shopping playbooks from initialize instructions or opendealer://assistant/shopping-playbooks.
