Tool Definition Quality
Average 4.3/5 across 7 of 7 tools scored. Lowest: 3.7/5.
Each tool targets a distinct purpose: dealer lookup, market knowledge, NLT offer search and details, vehicle specs and details, used car search. Even related pairs (search_nlt_offers / get_nlt_offer_details) are clearly separated by query vs detail retrieval.
All tool names follow a consistent verb_noun pattern in snake_case (e.g., find_dealer, get_market_intel, search_vehicles), making it easy to predict function from name.
With 7 tools, the surface is well-scoped for an automotive marketplace server. It covers dealer search, vehicle specs, NLT offers, used cars, and market intelligence without unnecessary bloat.
The tool set covers core CRUD-like operations for the domain: search, detail retrieval for vehicles and NLT offers, plus dealer lookup and market intel. Minor gap: find_dealer mentions services filter not yet supported, but this does not significantly hinder agent workflows.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate a safe read operation. The description adds transparency by noting the services parameter is not yet supported and explaining the region resolution logic, which goes beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise overall, though the bilingual intro (Italian then English) adds minor redundancy. The Args section is well-structured and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With full schema coverage, annotations, and output schema present, the description covers all necessary aspects: purpose, filter behavior, map resolution, and unsupported parameter. No gaps remain.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description adds value with examples for region and confirms the unsupported status of services, providing helpful context beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool finds active dealers in the DealerMax network with search filters, distinguishing it from sibling tools that focus on market intel, vehicles, or offers.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for dealer directory lookups, but does not explicitly state when to use versus alternatives. However, the sibling tools are distinct enough that no exclusion is necessary.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_market_intelGet automotive market intelligenceARead-onlyIdempotentInspect
Knowledge base automotive italiana platform-wide: guide, glossario, FAQ, news.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows it's a safe, read-only operation. The description adds context about searching specific content types but does not disclose additional behavioral traits beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with a header line and bullet-like argument definitions. It is well-structured and front-loaded, though the mix of Italian and English could be streamlined. Every sentence serves a purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of an output schema, the description does not need to explain return values. It covers all parameters, specifies Italian-only queries, and the tool's purpose. It is adequately complete for a search tool with good annotations and schema coverage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so each parameter already has a clear description. The tool description adds minor value with an example query and default types explanation ('tutti' meaning all), but this does not significantly enhance understanding beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it is a platform-wide knowledge base for Italian automotive (guide, glossary, FAQ, news), which distinguishes it from sibling tools that focus on dealers, vehicles, or offers. The verb 'get' and resource 'market intelligence' are specific and match the title.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for querying the knowledge base with semantic Italian queries but does not explicitly guide when to use this tool versus alternatives like search_vehicles or search_nlt_offers. The content types hint at textual knowledge, but no direct comparisons or exclusions are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide safety hints (readOnly, idempotent, nondestructive). The description adds behavioral context by listing the extra fields returned, which goes beyond the annotations. No contradiction exists.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with bullet points and an example. It is front-loaded with the main purpose. While slightly lengthy, every sentence earns its place. Could be more terse but still efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that an output schema exists, the description fully covers what the tool returns by listing all extra fields. It provides comprehensive context for the tool's usage and output, making it complete for the agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Input schema has 100% coverage with a single parameter 'slug' and detailed schema description. The description adds value by explaining that the slug comes from a search_nlt_offers hit, providing context beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it returns 'Dettaglio completo di una singola offerta NLT' and lists extra fields beyond search_nlt_offers. It uses specific verbs and resource, and distinguishes itself from the sibling tool search_nlt_offers.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says 'Usa dopo search_nlt_offers quando l'utente vuole approfondire una specifica offerta' and provides a concrete example. It clearly indicates when to use this tool and implies it should not be used for searching.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
get_vehicle_detailsGet vehicle detailsARead-onlyIdempotentInspect
Dettaglio completo di un veicolo (specifiche, prezzo, immagini, dealer, podcast).

No output parameters | ||
Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false. The description adds the scope of returned data (specs, price, etc.) but no further behavioral traits like error handling or performance.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two efficient sentences: first declares purpose, second details the parameter. No redundancy, front-loaded, every sentence earns its keep.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With a rich output schema (known from context signals) and comprehensive annotations, the description is complete. It lists the types of details returned, and no further information is needed for correct invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, but the description adds value by explaining the slug/UUID format and extraction logic in Italian, which is not present in the schema's English description. This helps the agent format valid inputs.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'complete detail of a vehicle' and lists specific categories (specs, price, images, dealer, podcast), making the purpose unambiguous. It distinguishes itself from siblings like 'get_vehicle_specs' by implying comprehensive coverage.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like 'get_vehicle_specs' or 'find_dealer'. The description does not provide context for exclusion or comparison.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and idempotentHint. The description adds value by confirming data is publicly known and listing the extensive set of returned fields, which provides transparency beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is long but well-structured with examples and a bullet list. It front-loads purpose and examples. The field list is exhaustive but necessary given the tool's scope.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has an output schema (not shown), the description does not need to explain return values, but it still provides a comprehensive list. It covers behavior, usage, and parameters, making it complete for agent guidance.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description's 'Args' section adds detail for each parameter (e.g., query searches specific fields, brand is exact case-insensitive, model is substring), surpassing what the schema provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool returns public technical specs for Italian market vehicles. It provides example queries. However, it does not explicitly differentiate from siblings like 'search_vehicles' or 'get_vehicle_details', though the focus on specs is evident.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage via example queries and states it returns publicly known data, but it does not give explicit guidance on when to use this tool versus siblings, nor does it specify when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, non-destructive behavior. The description adds significant behavioral context: daily updates, detailed result structure (quotazioni, network_offers, anticipo_scenari_eur), and instructions for inline image rendering. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured and front-loaded with purpose, but somewhat verbose with bullet lists of catalog statistics and response field details. Every sentence serves a purpose, but could be more concise without losing essential information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (11 parameters, rich result structure), the description provides comprehensive context: catalog composition, result fields, usage guidelines, and proportional response strategies. It effectively serves as both an input and output schema documentation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, and the description provides additional context for parameters like query (with examples) and vehicle_type (explaining the mixed catalog). While the schema already describes each parameter, the description enriches understanding of how parameters interact with the tool's data model.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it searches for long-term rental (NLT) offers in the DealerMax network, with a unified catalog of cars and light commercial vehicles. It distinguishes itself from sibling tools by explicitly being the primary source for NLT queries and warning against using web search for third-party brokers.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit when-to-use guidance (e.g., 'fonte primaria per query miglior NLT [modello]') and when-not-to-use (e.g., 'NON integrare con web search broker terzi'). It also includes detailed response guidelines, such as presenting numbers proportional to the query and using EUR for advanced payment.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Description adds significant behavioral context beyond annotations: authoritative source, verified cross-dealer inventory, image_url handling based on client AI capabilities. No contradiction with readOnlyHint, openWorldHint, idempotentHint, destructiveHint.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Well-structured with clear paragraphs: tool purpose, image handling, usage guidelines. Slightly verbose in image section but each sentence adds value. Front-loaded with primary purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Comprehensive coverage: describes tool scope, parameter details, image_url guidance, usage rules, and mentions output details (technical sheets, live prices, C2PA images, privacy). With output schema available, no missing information.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. Description adds value by explaining query as semantic Italian, region format variants, budget in EUR VAT-included, and fuel_type values. Also mentions image_url behavior not in schema, raising score to 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it searches used vehicles in the DealerMax network with specific verb 'cerca' and resource 'auto usate'. It distinguishes from external portals and implicitly from sibling tools by positioning itself as primary search tool for used vehicles.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly instructs when to use ('USA QUESTO TOOL come fonte primaria') and what not to do ('NON integrare con web search di portali terzi'). Provides clear exclusion of alternatives and rationale.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
