Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.6.0
Disambiguation3/5
Many tools have distinct purposes, but miniapp_project_map, miniapp_dependency_diagram, and miniapp_graph_stats overlap significantly as they all analyze project structure and dependencies. This creates ambiguity for an agent deciding which tool to use.
Naming Consistency3/5
Naming uses snake_case with consistent prefixes (local_mcp_, miniapp_), but the verb-noun pattern is inconsistent: some tools start with verbs (generate, inspect, understand) while others are nouns (project_map, launch_checklist). This mixed pattern reduces predictability.
Tool Count4/5
With 25 tools, the server covers a broad range of miniapp engineering tasks from optimization logging to security scanning. While slightly on the high side, the count is justified by the variety of functionalities and is not excessive.
Completeness4/5
The tool set covers most advisory and analysis needs for miniapp engineering, including inspection, dependency analysis, security scanning, blueprint generation, and context retrieval. The lack of tools for actually modifying project files is a minor gap, but likely intentional as a read-only advisor.
Average 3.2/5 across 25 of 25 tools scored. Lowest: 2.4/5.

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

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It only states the output is task lists but omits whether it modifies data, requires permissions, or has side effects. Critical behavioral context is missing.
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 description is a single concise sentence. While efficient, it lacks essential details about parameters and output, making it insufficiently informative.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema and schema descriptions, the description is severely incomplete. It fails to clarify parameter usage, return format, or behavioral context, leaving the agent underinformed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the tool description does not explain any parameters. The 'featureName' and 'phase' parameters have no added meaning beyond their types and enum values.
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 clearly states the tool's purpose: breaking down a feature into six task categories (requirements, UI, frontend, backend, QA, launch). It uses a specific verb and resource, and distinguishes from sibling tools that focus on other aspects like blueprint generation or security scans.
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?
No guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites, context, or exclusions, leaving the agent without decision support.
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 exist, so description must disclose behavioral traits. It only states output concept but not technical behavior: whether it modifies files, returns data, requires permissions, or has side effects. Critical gaps for a generation tool.
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?
Single sentence is concise but not structured; lacks parameter breakdown or formatting. For a tool with 4 parameters, the description could be enhanced with bullet points or hints while remaining concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Complex tool (generating blueprint with multiple components) but description is minimal. No output schema, no explanation of what 'blueprint' entails, no mention of limitations or dependencies. Insufficient for agent to fully understand context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% and description adds zero meaning to any of the 4 parameters (productName, brandName, depth, linkExistingProject). No explanation of what each parameter does or how to use 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?
Description uses specific verb 'generate' and resource 'engineering blueprint for WeChat Mini Program product', detailing coverage from positioning to launch. Clearly distinguishes from sibling tools which focus on analysis/optimization of existing projects.
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?
No guidance on when to use this tool vs alternatives, no prerequisites or exclusions mentioned. The description does not help the agent decide context for invocation.
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 are provided, so the description carries full burden for behavioral disclosure. It states it 'generates a map' implying a read operation, but does not mention permissions, resource usage (e.g., scanning many files), or whether it modifies the project. The agent cannot determine side effects or 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 a single sentence, concise and front-loaded. It begins with a reference to Understand-Anything which, while informative, adds slight overhead. Overall, it is efficient and to the point.
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 no output schema, the description should explain return values, but it only lists components ('pages, files, cloud functions, collections, and dependency edges'). The format parameter covers output format. However, the description lacks scope, performance implications, and explicit read-only nature. It is adequate but not comprehensive for a tool with 4 parameters and many siblings.
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 each parameter having a description. The tool description adds high-level context (knowledge graph approach, types of elements) but does not provide additional meaning beyond the schema for any parameter. Baseline 3 is appropriate as the schema already documents what each parameter does.
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 clearly states it generates a project map with specific components (pages, files, cloud functions, collections, and dependency edges) using a knowledge graph approach. It differentiates from siblings by mentioning a broader set of elements, but does not explicitly distinguish from similar tools like miniapp_dependency_diagram.
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?
No usage guidance is provided. The description does not indicate when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. This forces the agent to infer context from the tool name and parameters.
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 are provided, so the description must bear full burden. It only states that the tool 'explains', but the input schema implies it scans files (via projectPath and limit). This behavioral trait (file scanning) is not disclosed, and no side effects or permissions are mentioned, leading to low transparency.
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 extremely concise, consisting of a single sentence that front-loads the purpose. Every word serves a function. However, it could be slightly expanded to include behavioral context without becoming verbose, so it is not perfect but reasonably concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Without an output schema and with minimal description, the tool's behavior is underspecified. The description does not explain how the tool uses the input parameters, what the output looks like, or what 'scanning' entails. For a tool targeting beginners, this lack of context significantly reduces completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds no meaning beyond the input schema. While schema coverage is 67% (two parameters have descriptions), the description does not clarify the purpose of projectPath or how the parameters relate to the explanation process. The goal and limit descriptions are already in the schema, so the description adds no value.
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 clearly states what the tool does: explain the complete engineering process of a mini-app from requirements to launch. It uses specific verbs ('解释' meaning explain) and resources ('完整工程流程' meaning complete engineering process), differentiating it from sibling tools that focus on specific aspects like feature impact or file roles.
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?
The description provides no guidance on when to use this tool versus alternatives. With many sibling tools (e.g., miniapp_understand_feature_impact, miniapp_work_breakdown), explicit usage context is missing, leaving the agent to guess based solely on the name and description.
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 are provided,so description carries full burden. The description mentions 'read' but omits the safety gate: the confirmed parameter must be true to execute. This critical behavioral trait (default false, no read without confirmation) is not disclosed in the description.
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 a single sentence in Chinese, concise and front-loaded with the action. No wasted words, but could be more structured with additional contextual detail.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, no annotations, and a moderate number of siblings, the description is incomplete. It lacks usage guidance, behavioral nuance (confirmation), and details about the returned context format.
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 50% (only confirmed described). The description itself does not explain parameters beyond what the schema provides. The query parameter lacks description but the tool name implies it's the search query. Baseline 3 due to moderate coverage; no additional value added.
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 clearly states the action: calling a local knowledge base route search to read context related to the current mini-program/business. It specifies verb and resource, but does not differentiate from sibling tools like miniapp_relevant_context or miniapp_docs_lookup.
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?
No guidance on when to use this tool versus alternatives. The description implies it is for reading context, but does not specify scenarios where it is preferred over other context-related tools.
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 are provided, and the description only says 'output,' suggesting a read-only operation, but it does not explicitly state it has no side effects, permission requirements, or other behavioral traits. This leaves room for ambiguity.
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 a single concise sentence that front-loads the main action and output. It is efficient but lacks any additional context that might be helpful.
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?
The description lists output content types but omits details about return format, use cases, or when to invoke the tool. Given no output schema, more context would be beneficial.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 50% (only 'limit' has a description). The description does not explain any parameters, so it adds no value beyond what the schema already provides. The undocumented 'projectPath' parameter is not clarified.
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 clearly states it outputs statistics of a lightweight code graph, listing specific content types (node/edge types, route links, important nodes, risk tips). While it doesn't explicitly differentiate from sibling tools like miniapp_dependency_diagram, the focus on statistical summary distinguishes it implicitly.
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 usage when a statistical summary of the code graph is needed, but it does not provide explicit guidance on when to prefer this tool over siblings or 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must cover behavioral traits. It fails to mention whether the tool has side effects, requires specific permissions, or any limitations. The 4-tier structure is introduced but not explained, leaving uncertainty about what the tool actually does.
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 description is a single sentence, which is concise but lacks necessary details. It front-loads the core idea but is not fully self-contained, requiring the user to infer additional context.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 7 parameters, no output schema, and no annotations, the description is incomplete. It does not explain the four tiers, output format, or how to interpret results. The tool's complexity demands a richer description.
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 71%, so baseline is 3. The description does not add meaning to individual parameters beyond what the schema provides; it only mentions 'task' which ties to query/goal/featureName. No additional parameter semantics are offered.
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 clearly states the tool outputs a 4-tier context (Core/Near/Extended/Background) for tasks, specific to miniapp engineering. However, it does not differentiate from sibling tools like miniapp_inspect_project or miniapp_project_map, which may also provide context.
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 usage for task-based context retrieval ('按任务输出') but provides no explicit guidance on when to use this tool versus alternatives, nor any exclusions or prerequisites.
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 are present, so the description must fully disclose behavior. It only mentions analysis of impacts but does not state side effects, authorization needs, or whether it is read-only. The description is too vague to understand behavioral traits.
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 a single concise sentence that front-loads the purpose. It is appropriately sized for a simple tool with three parameters, though it could benefit from slight structuring.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of analyzing impacts across multiple dimensions (pages, cloud functions, etc.) and the absence of an output schema, the description does not convey what the analysis produces. The agent is left uninformed about the tool's output format or structure.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 67%. The description adds value for featureName by providing concrete examples (客户成片展示等) and for limit by stating the default and interpretation (命中文件). This goes beyond the schema, though projectPath lacks any description.
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 clearly states the verb 'analyze' and the resource 'feature name', listing specific impact areas (pages, cloud functions, etc.). This distinguishes it from sibling tools like miniapp_understand_file_role, though it does not explicitly differentiate.
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?
No usage context, when-not to use, or alternatives are provided. The description only states what the tool does, leaving the agent without guidance on choosing this tool over siblings.
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?
Annotations are absent, so the description must disclose behaviors. It mentions reporting status but also has a writeCache parameter that modifies local cache—a side effect not explicitly stated. The description implies read-only reporting but allows writes, lacking full transparency.
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 a single dense sentence that packs key information. It could be more structured (e.g., separate output description), but it is concise and front-loaded with purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool has 3 parameters and no output schema. The description does not explain the return format, what 'safe text files' means, or the implications of writeCache=true. This leaves gaps for an AI agent to fully understand the tool's behavior and results.
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 67%: limit and writeCache have clear descriptions, but projectPath lacks one. The overall description does not add parameter meaning beyond the schema. Baseline 3 is appropriate given moderate coverage.
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 states it computes hashes of safe text files and reports status changes relative to local cache, using CodeGraph incremental indexing. This is specific enough to distinguish from sibling tools that inspect projects or scan for security, though 'safe text files' is ambiguous.
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?
No guidance on when to use this tool versus alternatives like miniapp_security_quick_scan or miniapp_inspect_project. The description only explains what it does, not when to invoke it.
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 are present, so the description must fully disclose behavioral traits. It does not mention whether the tool reads files, requires network access, has side effects, or any limitations. The description is too brief to provide adequate transparency.
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?
The description is a single concise sentence that directly states the tool's function. It is front-loaded with the core purpose and contains no redundant or irrelevant information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists, so the description should clarify the return format or structure. It mentions explaining role, clues, and next steps, but does not specify how this information is presented (e.g., text, structured data). Given the complexity of the domain and many sibling tools, the description is insufficiently complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 67% (2 of 3 params described). The tool description adds no parameter-specific information; it does not explain the missing 'projectPath' parameter or add meaning beyond the schema for existing ones. The description fails to compensate for the schema's gaps.
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 clearly states the tool's action (explain), the resource (file role in a WeChat Mini Program project), and the output (upstream/downstream clues and next steps for beginners). It distinguishes from sibling tools like miniapp_understand_feature_impact and miniapp_understand_project_flow by its specific focus on file roles.
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?
The description provides no guidance on when to use this tool over alternatives, no exclusion conditions, and no context for when it is appropriate. It only states what the tool does, leaving the agent to infer usage from the name.
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 are provided, so the description must carry full behavioral transparency. It lists what the log records but does not disclose side effects, idempotency, append-only nature, or whether it modifies existing logs. Key behavioral traits are missing.
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 a single sentence that efficiently states the purpose and scope. It is front-loaded with the verb and key contents. Could be more structured with bullet points for clarity, but remains concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 13 parameters, no output schema, and no annotations, the description is too brief to provide complete context. It does not specify scope (per-session/project/user), required permissions, or return behavior. Important for an AI agent to use correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 31% (only roundType and outcome have examples). The tool description lists high-level categories but does not explain most parameters' meaning, structure, or constraints. For 13 parameters with low schema coverage, the description fails to compensate.
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 clearly states the tool appends an optimization log and lists the types of information recorded (user ideas, Codex decisions, skills referenced, file changes, verification results, safety boundaries). It distinguishes from siblings like local_mcp_read_optimization_log and local_mcp_optimization_log_status.
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 use after an optimization round but does not explicitly state when to use it vs alternatives, nor provide prerequisites or exclusions. The sibling tools suggest differentiation but description lacks explicit guidance.
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 are provided, so the description carries full burden. It only states that the tool 'outputs' suggestions, implying a read-only operation, but does not disclose any behavioral traits such as side effects, required permissions, or data freshness. The lack of transparency is notable given no annotations.
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 a single concise sentence that front-loads the core purpose. It avoids verbosity but could benefit from structured presentation (e.g., bullet points) for better readability, though it remains efficient.
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 the tool's simplicity (one optional parameter, no output schema, no annotations), the description provides the essential information about its function and filtering ability. However, it lacks details on output format or what 'skill routing' entails, leaving some gaps for a complete understanding.
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% with one parameter 'topic' having a clear description in the schema. The description adds no additional meaning beyond what the schema already provides, meeting the baseline for high coverage.
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 clearly states the tool's function: outputting skill routing and usage suggestions based on installed skills, with optional topic filtering. It differentiates from sibling tools by focusing on skill routing for mini-program projects, though it does not explicitly contrast with specific 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 usage when needing skill routing for mini-program projects based on installed Codex/Claude/agents skills, and the topic parameter suggests filtering use cases. However, no explicit guidance on when to use this tool versus alternatives or 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. Mentions 'reading local rules' but does not disclose whether the tool modifies any state, auth requirements, or rate limits. Insufficient for a read operation.
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?
Single sentence efficiently conveys purpose. No wasted words, but could be more structured for clarity.
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?
No output schema, but description lists output aspects. Lacks details on output format, side effects, or how the profile is constructed. Adequate but not thorough.
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?
One boolean parameter (includeSources) with full schema coverage. Description adds no extra meaning beyond schema, so baseline 3 applies.
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?
Description clearly states it reads local rules and produces a work profile covering communication, delivery, security, knowledge base, and coding habits. Distinguishes from siblings, none of which provide a user profile.
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?
No explicit guidance on when to use this tool versus alternatives. Does not mention prerequisites, exclusions, or context.
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?
With no annotations, the description should cover behavioral traits. It does not mention if the tool is read-only, what output format is returned (e.g., raw Mermaid text or a file), or any side effects like modifying files. The phrase 'generate' implies creation but without safety context.
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?
Single sentence conveying the core purpose and entities involved. No redundancy; every word is necessary.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 4 parameters and no output schema, the description should explain what the generated diagram looks like, how it's delivered, and error scenarios. It is too brief for a tool with multiple inputs and no explicit output details.
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 75%, so baseline is 3. The description adds the context of 'Mermaid' but does not elaborate on parameter specifics like how target or featureName are used (e.g., filtering, highlighting). The description adds minimal extra value beyond the schema.
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 clearly states the tool generates a Mermaid dependency diagram for specific entities (pages, files, routes, cloud functions, controllers, collections), providing a specific verb and resource. It distinguishes from siblings like miniapp_project_map or miniapp_graph_stats by focusing on dependency relationships.
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?
No guidance on when to use this tool vs. alternatives like miniapp_understand_project_flow or miniapp_graph_stats. No context on prerequisites (e.g., project must exist) or 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It only states it generates a checklist, but does not disclose side effects (e.g., if it modifies anything), output format, or prerequisites. For a non-mutating tool, safety is implied but not explicit.
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?
The description is a single sentence that efficiently conveys the tool's purpose and scope. No unnecessary words or repetitions.
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 the simplicity of the tool (one optional parameter, no output schema), the description covers the main areas but lacks details like checklist format, whether output is text or list, and how the parameter affects the checklist. It is minimally adequate but could be more complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must explain parameters. It mentions 'customer private album delivery' which relates to the 'includePrivateAlbum' parameter, but does not explain the parameter's effect or default behavior. This is insufficient for the agent to understand the parameter's role.
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 clearly states 'generate a check list before launching a WeChat mini program' and lists specific areas covered (cloud development, privacy, review, customer private album delivery). It uses a specific verb and resource, and distinguishes from sibling tools like miniapp_security_quick_scan which focuses on security.
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?
No guidance on when to use this tool versus alternatives, nor when not to use it. The description only explains what it does without providing 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?
With no annotations provided, the description carries full behavioral disclosure burden. It lists checked areas but does not specify if the tool is read-only, whether it modifies state, requires special permissions, or how results are processed. 'Quick scan' lacks behavioral detail.
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?
Single sentence in Chinese, efficient and front-loaded. No fluff; every part contributes to understanding the tool's core function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description omits critical context: output format, side effects, prerequisites (e.g., project must exist), and whether results persist. The tool appears complex but is underexplained.
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 has three parameters with 67% description coverage. The description mentions '扫描多少个安全文本文件' (how many security text files to scan) indirectly explaining 'limit', and uses '最多返回多少条发现' (max findings) for 'maxFindings'. However, 'projectPath' lacks context beyond the tool's purpose, so description adds moderate value.
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 clearly states the tool's purpose: a security quick scan for mini-program launch, checking specific security aspects like keys, sensitive logs, permissions, etc. It distinguishes itself from sibling tools by focusing solely on security scanning, using the verb '检查' (check).
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?
No explicit guidance on when to use this tool versus alternatives. The description implies pre-launch usage but does not mention exclusions or alternative tools for different security needs. Among siblings, tools like 'miniapp_launch_checklist' or 'miniapp_inspect_project' exist without differentiation.
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?
Without annotations, the description carries full burden but only states it 'generates a checklist'. Does not disclose if it modifies state, side effects, or what the output contains. No output schema available, leaving agent uninformed about tool behavior.
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?
Single sentence is concise and covers main purpose. However, it could be more structured (e.g., bullet list of actions) for clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 6 optional parameters and no output schema, the description lacks detail on return value, parameter dependencies, or workflow context. Incomplete for a tool likely involved in critical release steps.
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 parameter descriptions. Description adds no additional semantic value beyond listing the action types implicitly. Baseline 3 is appropriate.
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?
Description clearly states the tool generates a preflight checklist for specific actions (cloud function deployment, miniapp upload/audit/release, npm/github sync) to avoid common errors. Distinguishes from sibling tools like 'miniapp_launch_checklist' by being release-specific.
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
