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

Annotations already declare readOnlyHint and openWorldHint. The description adds no additional behavioral context beyond these annotations, which is acceptable but does not enhance transparency.

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 a single, efficient sentence that is front-loaded and contains no redundant information, making it highly concise.

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?

The description is sufficient for a simple Q&A tool with one parameter and annotations. It could mention the nature of the AI response, but the current text is adequate given the tool's simplicity.

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?

The input schema covers the single parameter with a clear description. The tool description adds no extra semantic meaning beyond what the schema provides, earning the baseline score.

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 verb 'ask' and the resource 'Webflow AI', specifying the scope 'anything related to Webflow API'. It effectively distinguishes this Q&A tool from sibling tools that focus on specific functionalities.

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 use for asking questions about Webflow API but does not explicitly state when to use this tool versus alternatives, nor does it provide when-not guidance.

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

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

Annotations already indicate readOnlyHint=false and openWorldHint=true. Description adds no extra behavioral context (e.g., side effects, idempotency, permission needs). Fails to clarify what the 'open world' side effects are.

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?

Description is one sentence, concise but vaguely worded with 'perform actions like'. Front-loaded with 'Designer Tool -', which is not essential. Could be more precise but is not overly verbose.

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's complexity (multiple actions via an array), the description is insufficient. No output schema, no explanation of action ordering or response format. The description does not tie the structured input schema to a coherent workflow.

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 50% but the tool description does not add meaning beyond what the schema provides. siteId has a detailed schema description, but actions and sub-properties are not augmented by the tool description. No compensation for missing schema documentation.

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 states it's an asset tool for actions like create folder, get all assets/folders, update. Clearly indicates the resource (assets) and actions. Distinguishes from siblings like style_tool or component_builder.

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 vs alternatives (e.g., data_cms_tool). No prerequisites or exclusions mentioned. The description simply lists actions without usage context.

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

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

Description adds behavioral context beyond annotations (modifies active page, supports two insertion modes). No contradiction with annotations (readOnlyHint=false, openWorldHint=true).

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 concise sentences front-loading purpose and usage distinction. No unnecessary words. Highly 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?

Covers core functionality and action modes. Lacks detail on component_schema usage, error conditions, or prerequisites (e.g., active page requirement). No output schema, so return values not mentioned. Adequate for a moderately complex tool.

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 50%, description does not add much parameter detail beyond schema. Implicitly references parent_element_id and slot_name but does not explain complex component_schema object. Adequate but could be improved.

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 inserts component instances on the current active page, with specific verbs and resource. It distinguishes two modes (insert_in_element, insert_in_slot), differentiating from sibling tools.

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 states when to use insert_in_element vs insert_in_slot. Provides clear context for each action type. Lacks explicit comparison with siblings or when not to use.

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

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

Annotations already show it is not read-only; the description's list of mutating actions (create, update, delete) aligns with that. No additional behavioral traits (e.g., permission requirements, side effects) are disclosed beyond what the schema provides.

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 a single run-on sentence with a long list of actions, making it hard to parse quickly. It could be split into multiple sentences or broken down for clarity. It is not concise.

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 of the input schema (multiple nested actions), the description fails to provide an overview of how actions are organized, typical usage patterns, or how to sequence operations. It is incomplete for effective 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?

The description does not explain the 'actions' parameter structure or how to invoke specific actions. It merely lists action names, leaving the agent to rely entirely on the schema, which is verbose but lacks high-level guidance.

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 lists specific CMS actions (get collection list, create collection, etc.), making it clear that the tool manages CMS collections and items. It distinguishes from sibling tools like data_comments_tool by focusing on CMS operations. However, it lacks a concise verb-resource summary.

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 other data tools. The description merely enumerates actions without contextual hints about selection criteria, prerequisites, or alternatives. The agent must infer usage from the tool name and action list.

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

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

Annotations already declare readOnlyHint and openWorldHint. The description adds context about the data included (author info, timestamps, resolved state, design-context metadata), which goes beyond annotations. No behavioral contradictions.

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 three sentences, front-loaded with the tool's role, and every sentence adds value. No wasted words.

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?

The lack of output schema means the description must convey return value info. It describes the comment structure (author, timestamps, content, resolved state, design-context metadata) but could mention the output format for list vs get operations. Still, it provides adequate context for a read-only tool.

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 the input schema already documents the 'actions' parameter and its nested actions. The description provides conceptual context but does not add new meaning to the parameters beyond 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 is for inspecting comment feedback discussions in Webflow Designer, explaining what a comment is and its metadata. It distinguishes itself from sibling tools like data_cms_tool and data_pages_tool by focusing specifically on comments.

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 explicitly says 'Use this tool to inspect feedback discussions' and explains the context (page location, breakpoint). It does not mention when not to use it or provide alternatives, but the context is clear enough for an agent to decide.

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

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

Annotations indicate readOnlyHint=false (writes possible) and openWorldHint=true, but the description adds no behavioral context such as side effects, permissions, or state changes beyond listing actions.

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 a single sentence but somewhat repetitive ('Data tool - Components tool'). It front-loads the purpose but could be more concise without losing meaning.

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 complex nested schema with multiple actions, the description is too sparse. It does not explain how to structure the actions array, required site_id, or output expectations.

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 0%, meaning the top-level 'actions' property lacks description. The description does not clarify parameter usage or the multi-action structure that is central to the tool.

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 states it's a 'Components tool' and lists actions (list, get, update) but is vague about the specific domain (Webflow components). It does not differentiate from siblings like 'component_builder' or 'data_cms_tool'.

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

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

Annotations provide readOnlyHint: false, so the description does not need to restate that. The description adds the enterprise requirement, but fails to disclose that multiple actions can be batched in one call, that actions are independent, or that destructive operations exist (e.g., deleting redirects). These behavioral traits are left to the schema.

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 sentences with no fluff. The first sentence introduces the tool generically, the second adds a critical prerequisite. Could be slightly more detailed for such a complex tool, but remains efficient 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?

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's complexity (multiple actions for both sites and pages) and lack of output schema, the description is insufficient. It omits page-related actions and does not explain the workflow between actions, leaving significant gaps for an 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?

The description does not describe the 'actions' parameter or its sub-properties, despite the schema having detailed descriptions. With 0% schema description coverage, the description fails to compensate, offering no added meaning 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 states it is a scripts tool that performs actions like listing and adding scripts, but it does not cover all actions in the schema (e.g., page script actions) and uses 'like', making it vague. It distinguishes from other tools by its name but lacks specificity.

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 sibling tools such as data_cms_tool or other data tools. The description only labels it as a 'Data tool - Scripts tool' without any context on alternatives or prerequisites.

The tool description adds minimal behavioral context beyond the 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 a single sentence, which is concise but too brief to be useful. Important information about the tool's capabilities is omitted. Conciseness should not sacrifice completeness; here it does.

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's complexity (many actions, required siteId, nested objects), the description is woefully incomplete. It does not explain the return value, does not hint at the depth of functionality, and does not prepare the agent for the complex input schema. The annotations provide minimal context, and the description fails to fill the gap.

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 50%, meaning many parameters lack descriptions. The tool description does not add any meaning for parameters; it only lists a few action types without explaining their structure or the required `siteId` and `actions` parameters. For example, it does not clarify that `actions` is an array of action objects with multiple specific types.

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 states it is a 'Designer Element Tool to perform actions like get all elements, get selected element, select element on current active page. and more.' It gives a general sense of the tool's purpose but does not specify all actions (e.g., mutations like remove_element, set_text) and does not differentiate from sibling tools like element_builder or style_tool. The verb 'perform actions' is vague.

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. The description does not mention prerequisites (e.g., need a siteId, need an active page) or when not to use it. The schema's siteId property has a detailed instruction to ask user for siteId, but that is not in the tool description itself.

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

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

Annotations already provide readOnlyHint and openWorldHint. Description adds no behavioral context beyond that.

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?

Short but slightly redundant; could be trimmed to one sentence. Efficient overall.

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?

Adequate for a simple retrieval with no inputs, but lacks detail on what the connection info contains or its structure.

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?

No parameters exist, so schema coverage is 100%. No additional param info needed.

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 retrieves connection info for the Webflow MCP app, but the first sentence is nearly identical to the tool name, adding little new information. It distinguishes from siblings by the resource type.

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 to use when user asks for connection info, but provides no guidance on when not to use or alternatives.

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

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

Annotations indicate readOnlyHint=false and openWorldHint=true, but the description does not clarify whether the tool downloads, caches, or returns a URL. The behavior beyond the schema is unclear.

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?

Three sentences, but includes filler phrase 'this is helpful'. Could be more terse without losing clarity. Adequate but not exemplary.

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?

No output schema, yet description does not hint at what the preview output is (e.g., thumbnail URL, image data). Also, the need for siteId with a URL-based tool is unexplained, creating incompleteness.

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% with good descriptions for both parameters. The tool description adds no new parameter meaning beyond the schema, so baseline score is appropriate.

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 'Get image preview from url' and lists supported formats, making the purpose specific and distinguishable from sibling tools like asset_tool or element_builder.

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 (e.g., asset_tool or data_sites_tool). The format constraints provide some usage restriction but no when-not or alternative suggestions.

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

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

Annotations indicate readOnlyHint=false, which implies mutation. The description mentions 'create', 'update', 'remove' which align with that, but adds no further behavioral traits like rate limits, side effects, or authentication needs. The schema descriptions carry most of the burden.

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 a single sentence that is concise but lacks structure. It front-loads the tool identity but is too brief to be informative. It could be improved with bullet points or more details.

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 complex nested schema with multiple actions and no output schema, the description is insufficient. It does not summarize the tool's overall behavior or mention data intensity of certain actions. The schema covers details, but the description should help the agent decide if this tool is appropriate.

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?

The description adds no meaning beyond the input schema; it merely repeats action names. The schema already provides detailed descriptions for each action. With 50% coverage, the description should offer additional context but does not.

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 style tool for actions like create, get, update, and remove. It identifies the resource (styles) and verbs, but does not differentiate from sibling tools such as component_builder or element_tool.

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 variable_tool or element_tool. It simply lists actions without any context about prerequisites or when to avoid.

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

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

Annotations indicate readOnlyHint=false (mutates) and openWorldHint=true (side effects). The description does not disclose behavioral traits beyond 'perform actions', lacking specifics on what gets created, updated, or deleted. It does not contradict annotations, but it adds minimal value beyond them.

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 a single sentence, concise but too brief for the tool's complexity. It could be improved by listing the main action categories (create, get, update, delete, query, rename). It sacrifices completeness for brevity.

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's complexity (14+ sub-actions) and lack of output schema, the description is insufficient. It does not cover the full range of operations or explain return values. The description is incomplete for an agent to understand the tool's capabilities.

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?

The description does not add meaning to the parameters; it only lists example actions. The input schema has detailed parameter descriptions, so the schema carries the burden, but with 50% schema coverage, the description could compensate. It does not help with parameter usage or semantics.

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 states it performs actions like create, get all, update variables, but it is vague and does not capture the full scope of operations (e.g., delete, query, rename). It fails to distinguish from sibling tools, though sibling tools are different categories. The purpose is somewhat clear but incomplete.

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?

There is no guidance on when to use this tool versus other tools. The description does not provide context for when it is appropriate, nor does it mention alternatives or exclusions. Sibling tools are diverse, so some implicit context exists, but explicit guidance is missing.

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

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

Annotations already declare readOnlyHint=true, indicating no side effects. The description adds the behavioral context that the tool should be called first, which is useful but not a technical behavioral disclosure 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 relatively short and front-loads the purpose, but the instruction to 'ALWAYS CALL THIS TOOL FIRST' is repeated unnecessarily, making it slightly less concise.

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 no parameters and no output schema, the description adequately explains its role and when to call it. However, it lacks specifics on what guidelines or best practices are provided, which would improve completeness.

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?

There are no parameters in the input schema (trivially 100% coverage). The description adds no parameter info, which is fine since there are none. Baseline 4 applies for zero-parameter tools.

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 provides guidelines and best practices for Webflow tools, and explicitly distinguishes it from functional siblings by instructing to call it first. The verb 'provides' and resource 'essential guidelines' are specific.

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 gives explicit guidance to 'ALWAYS CALL THIS TOOL FIRST BEFORE CALLING ANY OTHER TOOLS,' which is repeated for emphasis. This is a clear when-to-use directive, and while no alternatives are given, its unique role makes that unnecessary.

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

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

Annotations indicate a write operation (readOnlyHint=false) and potential side effects (openWorldHint=true). The description confirms insertion into a parent element, but fails to elaborate on behaviors like page modification, undo capabilities, or error handling. It adds some context beyond annotations but lacks depth.

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 two sentences, front-loaded with the tool category, and clearly conveys the core function. It contains no redundant information, though the 'Designer Tool' prefix is slightly extraneous. Efficient and well-structured.

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?

The description misses return value information (e.g., what is returned after insertion) and does not mention error conditions or prerequisites. Given no output schema, this is a gap. However, the description covers the main action and required inputs adequately.

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?

The input schema already provides detailed descriptions for siteId and actions (including nested properties), covering 50% coverage. The tool description summarizes 'HTML markup and optional CSS' but does not add new meaning beyond the schema. Baseline score is appropriate.

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 identifies the tool as a 'WHTML builder' that inserts elements from HTML and CSS strings into the active page, distinguishing it from sibling tools like element_builder or component_builder by focusing on raw string inputs.

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 explicitly states the tool accepts HTML markup and optional CSS rules and operates on the current active page, providing clear context. However, it does not explicitly exclude alternative tools or state when not to use it, but the usage scenario is well implied.

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