Server Quality Checklist
Latest release: v2.0.0
- Disambiguation5/5
Each tool targets a distinct action and resource (login, search, address management, cart, orders, server status). No two tools have ambiguous boundaries; the sequential steps (create_order vs submit_order) are clearly differentiated.
Naming Consistency4/5All tools use the 'shangou_' prefix and verb_noun pattern (e.g., check_login, set_address, add_to_cart). The naming is mostly consistent, though 'shop_menu' deviates slightly from a clearer 'get_shop_menu'. Overall predictable and readable.
Tool Count5/511 tools is well-scoped for a food ordering server. It covers the entire workflow from login to order submission without unnecessary bloat or missing critical steps.
Completeness4/5The set covers the core ordering flow (login, search, address, menu, cart, order creation, submission). Minor gaps exist (e.g., no remove-from-cart tool, no order history), but the stated purpose is fulfilled effectively.
Average 4.2/5 across 11 of 11 tools scored. Lowest: 3.5/5.

How is the quality score calculated?
The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).
Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.
Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).
Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.
Tool Scores
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description partially covers behavior by stating the return values (success status and screenshot) and hinting at potential need for specification selection. However, it lacks details on error handling, side effects, or permission requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise, consisting of two sentences that front-load the purpose and then list parameters and a crucial note. Every word adds value, with no unnecessary information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description provides basic return information and a note about specification selection, but it does not mention prerequisites (e.g., needing to be logged in) or error scenarios. Given the complexity of the tool (3 parameters, no output schema), it is minimally adequate but incomplete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for parameters, and the description essentially restates the parameter purposes from the schema. It adds no new semantic meaning beyond what the schema already provides, hence a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool adds a dish from a store to the shopping cart, with a specific verb and resource. It distinguishes itself from sibling tools like shangou_view_cart and shangou_create_order by focusing solely on the add-to-cart action.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no explicit guidance on when to use this tool versus alternatives like shangou_shop_menu or shangou_submit_order. It does not mention preconditions or context where this tool is preferred.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- 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 discloses that parsing dishes and prices is attempted but not guaranteed. However, it lacks details on error handling, authentication, or the nature of the output.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise—a single sentence plus a parameter hint. It is front-loaded with the main action and contains no unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has one required parameter and no output schema, the description covers the basic purpose. However, it does not specify what the return value looks like (e.g., list of items with prices) or any edge cases, which would be helpful for a view tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% coverage, and the description restates the parameter 'shop=店铺ID/URL' essentially matching the schema. No additional meaning or constraints are provided beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: viewing the current shopping cart content of a specific store. It also mentions an attempt to parse dishes and prices, adding specificity. This distinguishes it from sibling tools like shangou_add_to_cart or shangou_shop_menu.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It only describes what the tool does, without specifying prerequisites, context, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. Only states the listing action without mentioning login requirements, permissions, or side effects. Minimal behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two precise sentences: first defines purpose, second provides workflow context. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequately covers core purpose and a key usage tip, but does not address login requirements, output format, or error scenarios. Given no output schema or annotations, additional context would improve completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Zero parameters, schema coverage 100%, so baseline is 4. Description does not need to add parameter info.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool lists commonly used shipping addresses with index/name/contact, and differentiates from sibling shangou_set_address by noting the workflow ordering.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says to use this before ordering and then select an address via shangou_set_address, providing clear context and an alternative. Lacks explicit when-not-to-use, but sufficient for this simple tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It mentions the tool returns dish names and prices and that parsing is 'best effort', which is a useful behavioral trait. However, it does not disclose read-only nature or other typical constraints.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no redundant information. Every part contributes: purpose, parameter format, output description. Extremely concise and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite lacking output schema, description adequately states that output includes dish names and prices with a caveat. For a simple list tool with two params, it covers essential information. Minor missing details like pagination or error handling, but overall sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, and the description reiterates the same parameter explanations (shop as ID or URL, limit as count). It adds Chinese translation but no new semantic depth beyond schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool retrieves a store's menu/products (查看某店铺的菜单/商品), which is a specific verb+resource. It distinguishes from sibling tools like shangou_add_to_cart or shangou_search.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Description explains how to use parameters (shop and limit) but does not provide when-to-use or when-not-to-use guidance, nor alternatives. Context signals show siblings, but no explicit usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description covers prerequisite but does not disclose other behavioral details like rate limits, response format, or explicit read-only nature. Adequate but incomplete.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise single sentence covering purpose, parameters, and prerequisite with no redundant information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 parameters, no output schema), the description covers key aspects: purpose, parameters, and prerequisite. Lacks output format details but sufficient for agent invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, and description adds value with keyword examples (奶茶/汉堡/超市/水果) and clarifies limit meaning. Exceeds baseline by providing concrete usage context.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the tool searches for nearby deliverable shops/food with specific keyword examples, distinguishing it from sibling tools like shangou_shop_menu or shangou_list_addresses.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fully bears the burden. It discloses that the tool does not require authentication and specifies the type of information returned (playwright, profile, headless mode, amount limits). This adds behavioral context beyond the tool name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with a parenthetical list, which is concise and front-loaded. It could be slightly more structured, but there is no waste.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a server status tool with no parameters and no output schema, the description provides a good overview of what the tool returns. It lacks exact format details, but the examples given are sufficient for an agent to understand the tool's output.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero parameters, so baseline is 4. The description does not need to add parameter details. It correctly implies no inputs are required.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: querying server configuration and availability, listing specific items like playwright installation, profile directory, headless/headful mode, and amount limits. This distinguishes it from sibling tools like shangou_add_to_cart or shangou_search, which are action-oriented.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains parameter usage (keyword or index from shangou_list_addresses) and the follow-up action '选好后即可搜附近店' (after selection, can search nearby stores). It implies use after listing addresses, but does not explicitly exclude other scenarios.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fully discloses the tool's behavior: it stops before payment, returns amount and screenshot, and directs to manual payment via noVNC. It also mentions a server-side limit intercepting large amounts, ensuring the agent understands the non-destructive and advisory nature.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single Chinese sentence that efficiently conveys the main purpose, constraints, and post-action guidance. It is front-loaded with the primary action but could be slightly more concise by separating instructions. However, it remains clear and informative without excessive verbosity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite having no output schema and no annotations, the description sufficiently covers all aspects: the action, the required precondition (items in cart), the server-side limit, the returned data (amount, screenshot), and the manual payment method. This is complete for the tool's simple functionality.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 100% coverage for the single 'shop' parameter, describing it as '店铺ID或URL'. The description adds crucial context: '需已在该店加购' (must have added to cart in that shop), which goes beyond the schema and provides essential preconditions for usage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool generates a pending payment order for delivery, explicitly instructs to stop before submitting payment, and returns amount, screenshot, and manual payment guidance. The verb '生成' (generate) and resource '待支付外卖订单' (pending order) are precise, and it distinguishes itself from sibling tools like shangou_submit_order.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description specifies that the shop parameter requires a shop ID/URL and that items must already be in the cart. It warns about a server-side amount limit and guides users to manually pay via noVNC. Although it does not explicitly state when not to use the tool, it implies alternatives like shangou_submit_order for actual submission.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Describes the exact behavior: submits order, stops at checkout without payment, returns payment link and screenshot. Discloses that the link is session-bound and must be opened in the browser. No annotation contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
