Scored 2026-11-03 20:45 across 10 tools

Disambiguation4/5

Most tools target a distinct resource+action (search_inventory vs. get_vehicle vs. list_dealers vs. get_deal_thread vs. get_lead_status), so misselection is unlikely. The only soft overlap is submit_lead vs. start_shielded_inquiry (both initiate dealership contact for a vehicle) and get_lead_status vs. get_deal_thread (lead vs. shielded thread), but the descriptions make the privacy/consent distinction explicit enough to choose correctly.

Naming Consistency5/5

Every name follows a clean snake_case verb_noun pattern (get_vehicle, list_dealers, search_inventory, start_shielded_inquiry, send_counter_offer, burn_proxy_thread). Compound names like accept_deal_and_reveal stay within the same convention, so the pattern is predictable throughout.

Tool Count5/5

Ten tools is well within the sweet spot, and each one covers a distinct step of the buyer journey or thread lifecycle rather than duplicating functionality. No obviously redundant or trivial fillers are present.

Completeness4/5

The core lifecycle is covered end-to-end: discover dealers and vehicles, open a shielded thread or submit a lead, counter-offer, accept/reveal, and burn the thread, plus lead-status polling. Minor gaps exist: there is no way to list a buyer's active threads or leads (only by known ID), no lead cancel/withdraw equivalent to burn_proxy_thread, and no get_dealer for a single dealership record, which agents must work around via list_dealers.

A3.9/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden. It does disclose the key sensitive side effect: buyer PII is unlocked to the dealership, and this is gated on explicit buyer consent. However, it does not say whether the action is irreversible, what happens to the deal thread state, whether the buyer is notified, or what errors occur when consent is false.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences with the trigger condition and the sensitive consequence front-loaded. Every sentence carries meaning and nothing is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a high-stakes, consent-gated mutation with 9 parameters, no annotations, and no output schema, the description covers the core action but omits what the caller gets back, what happens to the thread after acceptance, and whether the reveal is reversible or final. More behavioral context would materially reduce misuse risk.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 100% description coverage, so the baseline is 3. The description reinforces the consent=true requirement and mentions the fields revealed (name, email/phone, appointment window), but it adds little beyond the already-complete schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource: accepting a verified Out-The-Door deal and revealing buyer identity. It also states the scope and effect (unlock real name, email/phone, appointment window to the dealership), which clearly distinguishes it from read-only siblings like get_deal_thread and get_lead_status.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives a clear precondition for use (the buyer approves a dealership's verified OTD quote) and repeats the consent requirement (consent=true). It does not explicitly name alternatives or state when not to use it, but the prerequisite is specific enough to guide invocation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

burn_proxy_threadBurn Proxy Identity & Permanently Block Dealer Follow-UpsAInspect

One-click privacy kill-switch: permanently closes a shielded deal thread and revokes its proxy relay email address so any subsequent BDC drip emails or follow-ups from that dealership are silently dropped.

Name	Required	Description	Default
`reason`	No	Optional reason (e.g., 'Purchased vehicle elsewhere', 'Unacceptable mandatory add-ons').
`thread_id`	Yes	The proxy deal thread_id to permanently burn.

TDQS

A3.6/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden and does real work: it discloses permanence, revocation of the relay address, and the downstream effect that dealer emails are silently dropped. What's missing is whether the thread and its history become unrecoverable, and whether any confirmation or permission is required.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with the destructive effect stated first and the consequence second. The 'one-click privacy kill-switch' framing is slightly promotional but does convey that no setup is needed.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive, irreversible action with no annotations and no output schema, the description explains the effect well but leaves recovery, thread-history fate, and any required confirmation unstated — gaps an agent would want closed before invoking.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with both thread_id and reason documented including an example reason, so the schema does the heavy lifting. The description adds no parameter-level detail beyond that, which is the baseline-3 case.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a concrete verb+resource pair: permanently closes a shielded deal thread and revokes its proxy relay email. That is far more specific than the name alone and clearly separates it from read-oriented siblings like get_deal_thread, though it never names a sibling to contrast with explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'One-click privacy kill-switch' implies the intent (cut off dealer contact) but never states when to use it versus alternatives such as accept_deal_and_reveal or send_counter_offer, nor any precondition or confirmation requirement. Usage is inferable but not guided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_deal_threadGet Shielded Deal Thread, Verified OTD Quote & Filtered Reply StatusBInspect

Inspect the current state of a shielded proxy deal thread, including physical lot verification answers, itemized Out-The-Door (OTD) quote, hidden add-on/markup warnings, filtered BDC auto-responder count vs. substantive human manager replies, Buyer Shield Pass status, 6-Digit Release Voucher state, and recommended next action.

Name	Required	Description	Default
`thread_id`	Yes	The unique thread_id returned by start_shielded_inquiry (e.g., 'dth_...').
`buyer_pass_id`	No	Optional Buyer Shield Pass ID ('bp_...') to resolve the pass status or latest auto-dispatched thread.

TDQS

B3.2/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. 'Inspect' implies a non-mutating read and the enumeration of returned signals gives genuine behavioral context about what the call reveals. However, it says nothing about permissions, what happens for expired/burned threads, or whether the recommended next action has side effects if followed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence that leads with verb and resource before the field list, with no filler preamble. The enumeration of seven returned artifacts is long but each item is substantive, so little is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description usefully enumerates the returned signals, which is the right compensation. But for a state-inspection tool in a multi-step deal workflow, it omits how to interpret or sequence those signals and gives no failure/edge-case behavior, leaving gaps an agent would hit on first use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and both parameters are documented in-schema with formats ('dth_...', 'bp_...'), so baseline 3 applies. The description adds no parameter-level meaning — it never mentions thread_id or the optional buyer_pass_id resolution path, leaving that entirely to the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Specific verb ('Inspect') plus a precisely named resource ('shielded proxy deal thread') that is clearly distinct from sibling operations like start_shielded_inquiry, accept_deal_and_reveal, or burn_proxy_thread. The field enumeration reinforces what the tool surfaces. It stops short of naming the closest alternative (get_lead_status), so an agent must infer the boundary itself.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit statement of when to call this versus get_lead_status, nor when to poll it during a thread's lifecycle. The phrase 'current state' implies a status-check use case, but nothing tells the agent when the tool is inappropriate (e.g., before start_shielded_inquiry, or after accept_deal_and_reveal). No guidance on the thread_id vs. buyer_pass_id choice either.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_lead_statusGet Lead Delivery & Billing Status (Dealer-Authenticated)AInspect

Check the delivery state, webhook/email attempts, duplicate flag, and billing ledger status of a submitted lead. Requires dealer_api_key.

Name	Required	Description	Default
`lead_id`	Yes	The unique lead ID returned by submit_lead.
`dealer_api_key`	Yes	Dealer API key for authentication.

TDQS

A3.8/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden and does disclose useful traits: the auth requirement (dealer_api_key) and the specific data classes returned. It stops short of noting error behavior for unknown lead IDs, retry semantics, or whether the call is purely read-only in effect.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences; the functional scope is front-loaded and the auth prerequisite follows. No filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, so the enumerated return facets (delivery state, attempts, duplicate flag, billing ledger) are exactly what the description needed to supply, and the auth prerequisite is stated. Only failure-mode behavior is unaddressed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so both parameters are already documented, including the lead_id linkage to submit_lead. The description only restates the auth requirement ('Requires dealer_api_key') and adds no format or constraint detail beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (check) and resource (status of a submitted lead) and enumerates the exact facets inspected: delivery state, webhook/email attempts, duplicate flag, billing ledger. This clearly separates it from siblings like get_vehicle, search_inventory, and submit_lead, though it never names a sibling explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'of a submitted lead' implies this is called after submit_lead, giving weak contextual guidance. There is no explicit when-to-use/when-not-to-use statement, no mention of what to do if the lead is missing, and no named alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_vehicleGet Full Vehicle Details, Classic Provenance & Dealership VDP InfoAInspect

Retrieve the complete canonical record for a single vehicle by its vehicle_id, 17-character ISO VIN, or pre-1981 vintage chassis/serial number. Returns full specifications, classic_details (era, build_style, numbers_matching, odometer_status), auction_details (if live auction), pricing & fee breakdown, insurance quote payload, all high-res photo URLs, dealer contact info, and source_url.

Name	Required	Description	Default
`id_or_vin`	Yes	The canonical vehicle ID (e.g., 'veh_...'), 17-character VIN, or pre-1981 classic chassis/serial number (e.g., 'JS27N0B118261').

TDQS

A3.7/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the behavioral burden. 'Retrieve' implies a read-only operation and the description enumerates the returned payload in useful detail, but it does not mention authentication requirements, not-found behavior, or other operational constraints.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the action and accepted identifiers, then lists the returned record contents. It is a dense single sentence, but the length is justified because there is no output schema to document return values elsewhere.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Because no output schema exists, the description appropriately enumerates the returned fields, including specifications, classic_details, auction_details, pricing, photos, dealer contact, and source_url. It is nearly complete for a read-only lookup, with the main gap being error or not-found behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter has 100% schema description coverage, so the baseline is 3. The description reinforces the identifier types, including '17-character ISO VIN' and 'pre-1981 vintage chassis/serial number', but these are already expressed in the schema and no additional syntax guidance is added.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb, resource, and scope: 'Retrieve the complete canonical record for a single vehicle' by ID, VIN, or vintage chassis number. This clearly distinguishes it from multi-vehicle siblings such as search_inventory, which an agent can infer without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The identifier types imply when the tool is appropriate: when you already have a vehicle_id, VIN, or classic chassis number and need the full record. However, it does not explicitly name alternatives like search_inventory for discovering a vehicle or state when not to use this tool, leaving routing guidance implied rather than explicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

`region`	No	Optional regional market filter (e.g., 'South Florida', 'Orlando', 'Tampa Bay', 'Atlanta', 'Texas').

TDQS

B3.2/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations, so the description carries the full disclosure burden: it does usefully reveal the returned payload (locations, platform, provenance, crawl timestamps, inventory counts, price ranges), which is real added context. However, it says nothing about read-only nature, result volume/pagination, rate limits, or freshness guarantees beyond the existence of crawl timestamps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence beginning with the verb and core resource, with the return-field inventory following. It is dense but each listed item adds information; no filler sentences or marketing fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no annotations and no output schema, the description does the minimum-plus by describing the returned data. It still leaves open default-scope behavior, result size/pagination, and why an agent would choose this over the inventory-search siblings, which matters for a broad listing tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the two optional parameters (state, region) are already fully documented in the schema. The description adds no filter semantics of its own; the phrase "across all 50 US states" only loosely gestures at geographic scoping.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a specific verb+resource ("List all indexed dealerships") and enumerates the entity types covered plus the fields returned, so an agent knows exactly what kind of data comes back. It does not explicitly name a sibling it is distinguished from, but the resource (dealership index) is naturally distinct from search_inventory or get_vehicle.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to call this versus search_inventory or get_vehicle, and no statement of what happens with no filters (presumably all 50 states). The state/region filters exist in the schema but the description never mentions them or when to narrow the query.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

B3.4/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the behavioral burden, and it usefully discloses that results come from live dealer/showroom inventory and live collector auctions, plus that auction prices may be current bids. It does not explain return shape, pagination behavior beyond the schema, sorting defaults, data freshness limits, or any auth/rate-limit constraints, so important behavioral context remains missing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The purpose is front-loaded, but the description is a single dense paragraph with long enumerations of showrooms, filter values, and examples. It is not structured for scanning and much of the enumeration duplicates or previews schema content without helping the agent decide how to call the tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 433 optional parameters, no annotations, and no output schema, the description is adequate on the search domain and source coverage but incomplete on operational details. It does not describe the result object, pagination envelope, ranking behavior, or how live auction versus dealer inventory results differ beyond listing_type, leaving the agent to infer these from the schema alone.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the schema itself documents the 433 optional parameters in detail, so the baseline is 3. The description adds some navigational value by highlighting major filter families and natural free-text query examples, but most parameter semantics are already supplied by the schema and the description does not materially deepen them.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Search live New, Used, Certified Pre-Owned, and Classic/Collector car inventory.' It clearly scopes the inventory sources to US franchise dealerships, specialist classic showrooms, and live collector auctions, which is enough for an agent to distinguish this from the lead/deal workflow siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies this is the tool for finding cars and gives extensive examples of supported queries and filters, such as free-text terms, classic_only, era, listing_type, and no_reserve_only. However, it does not explicitly state when to use this versus other tools or when not to use it, and the sibling tools are deal/lead workflow tools rather than alternative inventory search tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

`thread_id`	Yes	Active proxy deal thread_id.
`auto_negotiate`	No	Optional toggle to enable or disable autonomous multi-round Agent Playbook counter-offers on subsequent dealer replies.
`financing_type`	No	Optional updated payment/financing method.

TDQS

B3.4/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations supplied, the description carries the full behavioral burden. It does add genuinely useful context the schema cannot: the buyer's real phone and email stay completely hidden, and dealer add-on removal can be stipulated. However, it omits whether sending is irreversible, whether the offer is binding on the buyer, that auto_negotiate spawns autonomous multi-round replies, and what happens if the thread is inactive or burned.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with the core action first and the privacy guarantee second; no filler or repetition. It is dense but readable, though 'firm, structured' leans slightly promotional and the sentence becomes long with the parenthetical clause.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Ten parameters, no output schema, and no annotations make this a complex mutation tool, yet the description says nothing about the outcome of a send (does it return a thread message, an acknowledgment, a new state?) or how the autonomous negotiation toggles interrelate. Adequate for understanding what it does, thin for understanding what follows.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so every parameter (including auto_negotiate, max_auto_rounds, walk_away_otd_usd, cross_shop_leverage) is already documented in the schema. The description reinforces only two semantics — that the OTD figure is 'firm' and that add-on removal is an option — and adds no interpretation beyond that. Baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb (send) and resource (an Out-The-Door counter-offer) and pins down the channel ('on an active proxy thread'), which implicitly distinguishes it from siblings like start_shielded_inquiry (creates a thread) or accept_deal_and_reveal (closes one). It never names those siblings explicitly, so the differentiation is inferred rather than stated.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied by the phrase 'on an active proxy thread' — the agent can infer the thread must already exist and be live. There is no explicit when-to-use vs. when-not (e.g., burned threads, already-accepted deals), no stated prerequisites, and no pointer to get_deal_thread for checking thread state before countering.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

start_shielded_inquiryStart Shielded Proxy AI Relay & Agent Negotiation (Verify Lot Status & OTD)AInspect

Open a privacy-shielded, buyer-directed AI relay thread ('Verified Buyer #XXXX via DealerDirect AI Relay') with a dealership WITHOUT exposing the buyer's personal email or phone number. Operates as 50-state self-serve software where the buyer is sole principal ($0.00 deal/reveal/broker fee, $0.00 dealer fee forever). Sends an ADF/XML + plain-text checklist, a 15-second human Deal-Desk link, and a machine-to-machine JSON endpoint for Dealership AI Agents, and optionally runs a bounded multi-round Agent Auto-Negotiation Playbook.

Name	Required	Description
`buyer_zip`	Yes	Buyer's 5-digit US registration ZIP code (e.g., '33131') for accurate tax, title, tag, and OTD calculation.
`questions`	No	Optional custom verification questions for the sales manager (for classics, defaults automatically include cold-start video, undercarriage rust check, numbers-matching stampings, and enclosed shipping quote).
`promo_code`	No	Optional VIP / friend promo code to activate a complimentary Buyer Shield Pass.
`vehicle_id`	Yes	Canonical vehicle ID or 17-character VIN to verify and quote.
`buyer_pass_id`	No	Optional active DealerDirect Buyer Shield Pass ID (e.g., 'bp_...') to open a 2nd or 3rd concurrent shielded negotiation thread under the same flat pass.
`auto_negotiate`	No	If true (or when walk_away_otd_usd is set), activates the buyer's deterministic bounded Agent Auto-Negotiation Playbook to automatically strip hidden add-ons, cite lower competing quotes on the same pass, and counter across up to max_auto_rounds before pausing for buyer approval.
`financing_type`	No	Buyer's planned payment or financing method (default: 'undecided').
`target_otd_usd`	No	Optional opening firm Out-The-Door goal offer in whole USD.
`max_auto_rounds`	No	Maximum autonomous counter-offer rounds (1-5, default 3) when auto_negotiate is enabled.
`ready_to_sign_by`	No	Optional buyer timeline commitment (e.g., 'Saturday 5:00 PM').
`trade_in_summary`	No	Optional trade-in summary if applicable (e.g., '2019 Honda Accord EX-L, 54k miles, clean title').
`auto_strip_addons`	No	Clean-OTD audit rule (default true): automatically reply requesting removal of any hidden dealer add-ons/markups.
`walk_away_otd_usd`	No	Optional buyer-authorized maximum walk-away Out-The-Door ceiling in whole USD for bounded multi-round AI auto-negotiation.
`cross_shop_leverage`	No	If true (default), automatically cites any lower verified OTD quote from sibling threads on the same Buyer Shield Pass during auto-negotiation.
`request_cold_start_video`	No	Classic/collector option: explicitly request a cold-start & idle walkaround video.
`request_undercarriage_photos`	No	Classic/collector option: request lift/undercarriage frame & floorpan rust verification.
`request_numbers_matching_check`	No	Classic/collector option: request engine block/VIN stamping numbers-matching verification.
`request_enclosed_shipping_quote`	No	Classic/collector option: request an insured enclosed-carrier shipping quote to buyer_zip.

TDQS

A3.5/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations supplied, the description carries the full burden and does substantial work: it discloses that a named proxy thread is created, that three outbound artifacts are sent to the dealer, that auto-negotiation is bounded (max_auto_rounds) and pauses for buyer approval, and that add-on stripping and cross-quote citation happen automatically. Gaps remain on permission/auth requirements, idempotency, and whether a thread is created or reused when buyer_pass_id is present.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core capability is front-loaded in the first sentence, which is good. However, the middle sentence carries marketing padding that does not help an agent act ('50-state self-serve software', '$0.00 deal/reveal/broker fee, $0.00 dealer fee forever'), and the final sentence packs four distinct delivery mechanisms plus optional negotiation into one unwieldy clause.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For an 18-parameter mutating tool with no annotations and no output schema, the description explains the outbound side well but leaves the return contract entirely unstated, including whether a thread ID is produced for use with get_deal_thread and burn_proxy_thread. Failure modes, timing expectations, and what the buyer/agent must do next are also unaddressed, so an agent cannot plan the follow-up call from this description alone.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so every one of the 18 parameters is already documented in the schema, setting the baseline at 3. The description restates the auto-negotiation behavior (strip hidden add-ons, cite lower competing quotes, bounded rounds) but mirrors the schema wording rather than adding new semantics such as units, precedence between auto_negotiate and walk_away_otd_usd, or what happens if target_otd_usd exceeds walk_away_otd_usd.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource: open a privacy-shielded, buyer-directed AI relay thread with a dealership, and describes the artifacts it emits (ADF/XML + plain-text checklist, deal-desk link, JSON endpoint for dealer agents). It is clear what the tool does, but it never differentiates itself from siblings such as submit_lead or accept_deal_and_reveal, so an agent must infer the boundary between starting a shielded thread and submitting a plain lead.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied rather than stated: the tool is what you call to verify lot status and OTD under a shield, and optional auto-negotiation is gated on auto_negotiate/walk_away_otd_usd. There is no explicit when-not guidance (e.g., when to prefer submit_lead, or what to do if a thread already exists beyond the buyer_pass_id note in the schema) and no prerequisites or sequencing against get_deal_thread or burn_proxy_thread.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

submit_leadSubmit Qualified Buyer Lead to DealershipAInspect

Submit a buyer inquiry/lead directly to a participating dealership for a specific vehicle or general inventory inquiry. Requires explicit buyer consent (consent=true) and at least one contact method (buyer_email or buyer_phone). Returns a lead_id and delivery status.

Name	Required	Description
`consent`	Yes	Explicit buyer consent flag. Must be true to create and deliver the lead to the dealership.
`message`	No	Buyer's intent, questions, test-drive request, or trade-in/insurance notes.
`dealer_id`	No	Dealer ID (optional if vehicle_id is provided; required for general dealer inquiries).
`buyer_name`	Yes	Full name of the prospective buyer.
`vehicle_id`	No	Vehicle ID or 17-character VIN the buyer is inquiring about.
`buyer_email`	No	Buyer's email address (at least one of buyer_email or buyer_phone is required).
`buyer_phone`	No	Buyer's phone number (at least one of buyer_email or buyer_phone is required).

TDQS

A3.6/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It usefully discloses the consent gate, the contact-method requirement, and that a lead_id plus delivery status come back, but it omits important behavior for a write tool that transmits PII to a third party: idempotency/duplicate handling, what happens if delivery fails, and whether the dealership is notified.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with what the tool does and followed by prerequisites and return values. Every sentence carries information an agent needs, with no repetition of the title or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description compensates by naming the return values (lead_id, delivery status), and it covers the consent and contact requirements across all 7 documented parameters. Remaining gaps are failure semantics and the meaning of delivery status values, which are minor for a submission tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so every one of the 7 parameters is already documented in the schema. The description only restates the consent and contact-method rules rather than adding syntax, format, or edge-case meaning beyond the structured fields, so the baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource ('Submit a buyer inquiry/lead') and explicitly covers both operating modes: a vehicle-specific inquiry or a general inventory inquiry. It is clearly differentiable from read-only siblings like get_lead_status and search_inventory, though it never names them.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states two hard preconditions (consent=true, at least one of buyer_email/buyer_phone), which is real usage guidance. However, it never says when to prefer this tool over a sibling (e.g., when a lead already exists or the buyer should be pointed to list_dealers), and gives no when-not-to-use case.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
