GSAP MCP Server

Server Quality Checklist

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

Latest release: v1.0.0
Disambiguation3/5
While many tools have distinct purposes, the large number leads to overlap. For example, multiple timeline-related tools (create_sync_timeline, sync_timeline_playback, timeline_scrubber) could be confused, and generic tools like sequence_animation and parallel_animation overlap with timeline and batch tools.
Naming Consistency3/5
Tool names generally follow a verb_noun pattern, but there are inconsistencies: some use 'generate' vs 'create', and several lack a verb (e.g., svg_morph_animation, timeline_scrubber). The mix of English and Chinese descriptions also adds inconsistency.
Tool Count2/5
With 43 tools, the server is excessively large for a typical MCP server. While GSAP is a complex library, this many tools could be reduced by combining related functionalities into fewer, more composable tools.
Completeness5/5
The tool set covers virtually all major GSAP features: basic animations, timelines, scroll, SVG, text, physics, 3D, responsive, debugging, performance, and plugin management. It is very comprehensive for the GSAP domain.
Average 2.2/5 across 43 of 43 tools scored. Lowest: 1/5.

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

Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden but conveys no behavioral information. The agent cannot determine if this tool creates, plays, or defines an animation, nor what side effects or authentication needs exist.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness1/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely short but fails to provide necessary information, making it under-specified rather than concise. It does not earn its place as a useful description.
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 tool's complexity (nested object parameters, no output schema, and many sibling tools), the minimal description is completely inadequate. The agent cannot effectively select or invoke this tool correctly.
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 description adds no meaning to the parameters autoPlay and sequence. The parameter semantics are entirely undocumented, leaving the agent without guidance on parameter usage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose1/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description '序列动画' is a tautology, simply restating the tool name 'sequence_animation' in Chinese. It lacks a verb or specific resource, providing no clear indication of what the tool does.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given on when to use this tool versus the numerous sibling tools such as create_timeline_animation or create_stagger_animation. The description offers no context for appropriate usage.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Since no annotations are present, the description carries the full burden of disclosing behavioral traits. It omits any information about side effects, required permissions, or output behavior (e.g., whether the animation is applied instantly, returns an ID, etc.). This is insufficient for a tool that creates animations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness1/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single phrase that repeats the tool name. This is under-specification, not conciseness. Every sentence should earn its place; this one does not add value beyond the name.
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 tool's complexity (3 parameters, 2 required, no output schema, no annotations), the description is critically incomplete. It fails to explain the tool's purpose, how keyframes work, or what the output is. The description is inadequate for an agent to use the tool 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?
The input schema covers 3 parameters with only 33% description coverage (only 'target' has a description in Chinese). The tool's description adds no parameter-level meaning beyond what the schema provides. For example, 'keyframes' expects an array of objects with progress and properties, but the description does not explain this structure or constraints. The baseline of 3 is lowered due to the low schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose1/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description '创建关键帧动画' is essentially a translation of the tool name, providing no additional purpose. It fails to differentiate from numerous sibling tools like create_timeline_animation or create_stagger_animation, all of which create animations. The description lacks a specific verb and resource context.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
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 gives no context, prerequisites, or exclusions, leaving the agent to guess the appropriate scenario for keyframe animation creation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It gives no behavioral details such as whether the tool detects orientation changes, applies animations, or requires external triggers.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness1/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely short but not valuable. It lacks front-loaded critical information and every word is wasted. A useful description would be concise but 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?
For a tool with 4 parameters, 3 required, and nesting, the description is completely insufficient. No output schema, no explanation of return values or side effects. The context signals indicate complexity, but the description fails to address it.
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 coverage is 75% (3 of 4 parameters described). However, the description adds no meaning beyond the schema; it does not explain the expected structure of the nested objects (portraitAnimation, landscapeAnimation) or how target selector is used.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose1/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description is a Chinese phrase meaning 'responsive orientation change', which is a tautology of the tool name. It does not specify the action (detect, apply, animate?) or distinguish from sibling tools like responsive_breakpoint or responsive_scaling.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
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. With many sibling tools focusing on animations and responsiveness, the description provides no context to aid selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description lacks any behavioral disclosure. It does not state whether the action is read-only or destructive, what effects occur (e.g., animation playback), error handling, or required permissions. The agent has no insight into side effects or safety.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness1/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely short (4 characters in Chinese), which is under-specification rather than conciseness. It contains no actionable information. Every sentence should earn its place, but this description provides nothing useful.
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 absence of output schema and annotations, the description should compensate with rich behavioral and usage context. With 4 parameters and many sibling tools, the description is completely inadequate. It fails to explain what the tool returns or how it behaves, leaving the agent unable to use it 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 75% (3 of 4 parameters have descriptions in the schema), so the baseline is 3. However, the tool description adds zero value beyond the schema—it does not explain parameter relationships, formats, or constraints. The schema descriptions are minimal (e.g., 'SVG路径数据'), and the tool description should have supplemented them, but it does not.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose1/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description is a Chinese translation of the tool name ('文本路径动画' = 'text path animation'), providing no additional clarity. It is essentially a tautology, repeating the name without explaining the tool's function or its distinction from sibling tools like 'svg_path_animation'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No usage guidelines are provided. The description does not indicate when to use this tool over alternatives such as 'svg_path_animation' or 'text_reveal_animation'. There is no mention of prerequisites, use cases, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose any behavioral traits. It does not explain how the tool handles parallel execution, duration, or animation order. The schema reveals syncMode and animations but the description adds no context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely short (one word), but this is under-specification rather than conciseness. It does not front-load useful information or justify its brevity by relying on rich schema or annotations.
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 complexity of the tool (parameters with enum and nested array objects, no output schema, no annotations), the description is wholly inadequate. An agent cannot infer when or how to invoke the tool correctly.
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%, meaning no parameter descriptions exist in the schema. The description adds no meaning beyond parameter names. For a tool with enum and array parameters, this is insufficient for an agent to understand values and usage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose1/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description is simply '并行动画' (Chinese for 'parallel animation'), which is a tautology of the tool name. It does not specify what the tool does, what resources it acts on, or how it differs from sibling tools like sequence_animation or sync_timeline.
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. Among many sibling tools (e.g., sequence_animation, create_sync_timeline), there is no indication of the intended use case.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description bears full burden. It fails to disclose any behavioral traits such as what the tool modifies, side effects, or requirements. The description is essentially just the title.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness1/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely under-specified; a single phrase does not provide enough information. This is not conciseness but omission.
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?
With 5 parameters, no output schema, and no annotations, the description is completely inadequate. An agent cannot determine the tool's functionality, prerequisites, or return value.
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 descriptions cover 80% of parameters (in Chinese), but the tool description adds no extra meaning. It merely repeats the concept of responsive scaling without elaborating on how parameters like target, baseSize, minSize, maxSize, or unit are used.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description is '响应式缩放' (responsive scaling), which is vague. It does not specify what exactly is scaled or how, and does not differentiate from siblings like responsive_breakpoint or responsive_orientation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
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. With 40+ sibling tools, the agent has no hints about selection criteria or context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It provides no information about whether the tool modifies DOM, is destructive, requires specific element types, or how it handles existing content. This is a critical gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
While only one sentence, it is too brief and under-specified. It provides no structured information, front-loading nothing useful. True conciseness would include essential details without verbosity.
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?
Despite moderate complexity (5 parameters, no output schema), the description is completely inadequate. It fails to explain the typewriter effect, cursor behavior, or interaction with page elements, leaving the agent without sufficient context.
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 adequate param descriptions (e.g., '要显示的文本'). The description adds no additional meaning beyond the schema, meeting the baseline of 3 for high coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose1/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description '打字机效果动画' is a tautology, repeating the tool name in Chinese without specifying the action or resource. It does not clarify that the tool animates text by revealing characters one by one in a target element.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
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 sibling tools like text_reveal_animation or text_scramble_animation, leaving the agent without differentiation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It fails to mention any behavioral traits such as whether the tool modifies existing elements, requires authentication, has side effects, or returns any data. For a tool with 6 parameters including nested objects, this is a critical gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely short (one phrase) but at the expense of clarity. It is under-specified rather than concise; every word should earn its place, and here they fail to convey essential information. The structure is not front-loaded with key details.
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 tool's complexity (6 parameters, nested objects, enums, no output schema), the description is entirely inadequate. It does not explain the tool's purpose, behavior, or return values. The agent cannot reliably use this tool based on the description alone.
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% (4 of 6 parameters have descriptions), which is moderate. However, the tool description adds no information about parameters beyond what is already in the schema. It does not clarify the meaning of parameters like 'position' (nested object) or 'lightType' beyond the enum names.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description '3D光照动画' is a vague phrase that restates the tool name without a clear verb or resource. It indicates the domain (3D lighting animation) but does not specify what action the tool performs (e.g., create, apply, control). Among sibling tools like 'transform_3d_animation' and 'camera_3d_animation', there is no differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
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. No context, prerequisites, or exclusions are mentioned. The agent receives no help in deciding between this and similar 3D animation tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fails to disclose any behavioral traits. It does not mention whether the animation mutates the SVG, required permissions, or side effects. The description is purely nominal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is only 5 characters in Chinese, but it is under-specified. It does not earn its place because it adds no information beyond the tool name.
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?
For a tool with 5 parameters, no output schema, and no annotations, the description is completely inadequate. It fails to explain what the animation does, how parameters interact, or any usage context.
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?
Although schema coverage is 80%, the parameter descriptions are minimal translations of parameter names (e.g., 'toClip' → '结束裁剪'), adding little semantic value. No formats or constraints are explained beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'SVG裁剪路径动画' is essentially a Chinese translation of the tool name, providing no verb or specific action. It merely restates the name, making it a tautology. It does not distinguish from sibling tools like svg_mask_animation.

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 4 parameters, no output schema, no annotations, and many similar sibling tools, the description is completely inadequate. The agent cannot determine how to use the tool 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?
The description adds no additional meaning beyond the input schema. With 50% schema description coverage (only 2 of 4 parameters have descriptions), the description does not compensate by explaining parameters like direction (reveal/hide).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'SVG遮罩动画效果' is vague, only indicating the domain (SVG mask animation) without a specific verb or resource. It does not distinguish from sibling tools like svg_morph_animation or svg_clip_animation.

Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise but at the expense of clarity. It is front-loaded but lacks substantive information. The brevity is not effective communication.
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 complexity of 3D animation and many sibling tools, the description is severely incomplete. It does not cover return values, usage context, or relationship to other 3D tools. Output schema is absent.
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 60% (descriptions for target, container, cameraPosition). The description adds no new parameter insight; it relies entirely on schema. Baseline of 3 is appropriate given moderate coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description is a generic phrase '3D相机动画' (3D camera animation). It lacks a specific verb and does not differentiate from siblings like 'scene_3d_animation' or 'transform_3d_animation'. The purpose is vague.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No usage guidance is provided. With many sibling tools (e.g., transform_3d_animation, scene_3d_animation), the agent has no information on when to use this tool versus alternatives.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely short (5 characters) but lacks necessary detail. It is under-specified rather than concisely informative, making it insufficient for a tool with three parameters and nested objects.
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 tool has three parameters (one a nested object), no output schema, and no annotations, the description is completely inadequate. It does not explain what the tool returns, how to interpret results, or any side effects, leaving the agent without essential context.
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 the schema includes descriptions for two parameters (duration and threshold) in Chinese, the description does not explain their purpose or usage. Metrics parameter lacks a description entirely, and the high-level description does not compensate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description '性能监控' is a direct translation of the tool name, essentially a tautology. It does not specify what kind of performance is monitored (e.g., FPS, memory) or how it differs from sibling tools like 'animation_profiler' or 'optimize_animation_performance'.

Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely short (5 characters), which is not concise but underspecified. It lacks structure and does not provide enough information for an agent to use the tool correctly.
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 tool's complexity (physics parameters, nested objects) and the absence of an output schema, the description is severely incomplete. It does not explain return values, behavior, or how the animation is applied.
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 descriptions for all 5 parameters (mass, target, tension, friction, properties). While the tool description adds no extra meaning, the schema already explains each parameter sufficiently, resulting in a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description '弹簧动画效果' (spring animation effect) is too vague. It does not specify what the tool does (e.g., applies a spring animation to a target element). It also fails to distinguish from sibling tools like physics_draggable or create_interactive_animation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No usage guidelines are provided. The description does not indicate when to use this tool over alternatives, nor does it mention any prerequisites or context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, and the description does not disclose any behavioral traits such as read/write nature, side effects, permissions, or rate limits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise but at the expense of clarity and usefulness. The single phrase does not earn its place as it provides no actionable information.
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 tool's complexity (5 parameters, nested objects, 3D animation) and lack of output schema, the description is grossly inadequate. It should explain return values, object structure, or animation behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 80% with basic descriptions, but the tool description adds no additional meaning beyond what is already in the schema. Baseline score of 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description is a vague phrase '3D场景动画' (3D scene animation) that does not specify the action or resource. It fails to distinguish from siblings like camera_3d_animation or lighting_3d_animation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
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. the many sibling animation tools. No context about prerequisites or alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It only mentions the license requirement, omitting details like whether the tool modifies SVG attributes, what triggers the animation, or if it is destructive. The description fails to inform the agent about side effects or permissions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief but under-specified. It could be concise while providing more detail; currently it wastes the opportunity to add value.
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 tool has 5 parameters, no output schema, and no annotations, the description is critically incomplete. It does not explain the animation behavior, return value, or how parameters interact.
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 only 20% (only 'selector' has a description). The description adds no parameter information, leaving duration, direction, strokeColor, and strokeWidth unexplained. This is insufficient for correct parameter usage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'SVG绘制动画' (SVG drawing animation), which clarifies the general purpose of animating SVG drawings. However, it does not differentiate this tool from siblings like svg_path_animation or svg_morph_animation, leaving ambiguity about specific use cases.
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 only additional note is the license requirement, which is a prerequisite but not usage 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?
With no annotations, the description must convey behavioral traits. The description only states it's an effect, without explaining what 'reveal' means (e.g., sliding in, fading?), whether it mutates the DOM, or any side effects. No behavioral details beyond the name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
While very short (one phrase), the description is under-specified. It does not front-load actionable information; it simply restates the tool's purpose in a way that adds no value beyond the name. Conciseness without informativeness is not effective.
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 tool has four parameters, no annotations, no output schema, and operates in a rich context of sibling text animations, the description is grossly incomplete. It fails to explain the animation behavior, how direction affects reveal, the role of ease and duration, or what selector targets. The agent cannot use this tool correctly without guessing.
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 only 25% (only 'selector' has a description). The description adds no parameter information. For three of four parameters (ease, duration, direction), the agent has zero semantic clues from either schema or description, forcing complete reliance on parameter names and defaults.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description '文本揭示动画效果' is a tautological restatement of the tool name in Chinese, translating to 'text reveal animation effect'. It uses a vague noun phrase instead of a specific verb+resource structure, and it fails to distinguish this tool from siblings like text_split_animation or text_scramble_animation.
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 the many sibling text animation tools. There are no prerequisites, context, or alternative recommendations, leaving the agent to guess based solely on the name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations and a description that is merely a label, no behavioral traits (e.g., side effects, authorization needs, or output) are disclosed. The tool's behavior remains opaque.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise (one phrase) but sacrifices clarity and completeness. A tool description should provide context, not just a label.
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 nested objects in the schema and no output schema, the description fails to explain what results the tool produces or how to interpret the configuration. It is incomplete for effective use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Without annotations, the description must disclose behavior, but it only states the purpose. No mention of whether the tool is read-only, modifies anything, or its output format. Agents cannot infer side effects or permissions.
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 extremely concise (single phrase) but lacks structure. It is not overly verbose, but it could be more informative without sacrificing brevity.
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 presence of many sibling tools and lack of output schema, the description is insufficient. Agents cannot determine what the analysis returns or how to interpret 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 coverage is 100% with all parameters described. The tool description adds no extra meaning beyond the schema, so baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Animation performance analysis' clearly indicates the tool's purpose but is too brief and does not differentiate from sibling tools like 'optimize_animation_performance' or 'performance_monitor'.
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 any prerequisites or when-not-to-use conditions. The description lacks context for agent decision-making.
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 disclose behavioral traits. It only states the creation action, with no information about side effects, required permissions, or whether it modifies existing state. The description is insufficient for safe usage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single short sentence, which is too brief for a tool with three parameters and nested objects. It lacks structure, front-loading of key information, any additional helpful 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?
Given the tool's complexity (nested array input, multiple sibling tools, no output schema, no annotations), the description is far from complete. It fails to explain what constitutes a 'complex' animation, how to use the animantions parameter, or what the result is.
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 coverage is 67%, with two parameters having descriptions. However, the tool description adds no additional meaning or context for the parameters, such as how the 'animations' array component is structured or what 'options' and 'timelineId' accept. It does not compensate for the missing 33% 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 action '创建复杂的时间轴动画序列' (create complex timeline animation sequences) with a specific verb and resource. However, it does not differentiate this tool from sibling timeline or animation tools, such as 'create_sync_timeline' or 'create_stagger_animation'.
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 the many sibling tools. There is no mention of prerequisites, context, 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 must disclose behavioral traits. It provides none, e.g., whether the animation modifies the DOM, what happens if start > end, or the effect of autoRotate. This is insufficient.
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 extremely concise (one sentence), which saves space, but it sacrifices detail. It is front-loaded but not sufficient for a complete understanding.
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 6 parameters, no output schema, no annotations, and a one-line description, the tool is poorly documented. An AI agent would lack critical information about behavior, defaults, and return values.
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 coverage is only 33%; only 'selector' and 'pathSelector' have descriptions, but these add little beyond the parameter names. Parameters like start, end, duration, and autoRotate lack any description, leaving their meaning ambiguous.
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 'SVG path following animation' clearly states the tool's purpose: animating an element along an SVG path. It is specific and distinguishes from sibling tools like svg_morph_animation or svg_draw_animation, but the brevity limits nuance.
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 (e.g., svg_morph_animation, svg_draw_animation) or when not to use it. The description lacks context for appropriate usage.
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 should disclose behavioral traits. It only states 'Create stagger animation effect' without mentioning that staggering applies sequential delays to multiple targets, or any side effects, permissions, or response details.
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?

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 tool's complexity (nested 'properties' object, no output schema, many siblings), the description is insufficient. It does not explain return values, the staggering mechanism, or how parameters interact.
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 75% (most parameters have Chinese descriptions). The description itself adds no extra meaning beyond the schema, so it meets the baseline for moderate coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description is a single phrase '创建交错动画效果' (Create stagger animation effect), which states the verb and resource but is vague about what a stagger animation entails. It does not distinguish this tool from sibling animation tools like create_keyframe_animation or create_timeline_animation.
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 lacks context about prerequisites or scenarios where stagger animation is appropriate compared to other animation types.
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 the full burden. It does not disclose whether the tool is read-only or modifies state, nor does it mention side effects, permissions, or other behavioral traits. The term 'optimize' is vague and could imply modifications.
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 short sentence in Chinese, which is concise but somewhat under-specified. For a tool with 4 parameters, more structured information would be beneficial without losing conciseness.
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, no output schema, and no annotations, the description is insufficient. It does not explain return values or how to interpret the 'performance suggestions'. The sibling tools indicate a rich context, but the description fails to situate this tool within that context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already fully documents each parameter. The description adds no additional semantic meaning beyond the schema, placing it at the baseline of 3.
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?

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?
描述明确表述了工具行为：检查浏览器兼容性和特性支持。与所有动画相关的兄弟工具形成鲜明对比，易于区分。
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?
描述未提供何时使用或何时不使用该工具的明确指导。虽然从名称和兄弟工具可推断出它用于兼容性检查，但缺乏替代方案说明。
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 burden for behavioral disclosure. It only states 'sync playback', failing to explain what synchronization entails (e.g., start/stop/seek together), side effects, permissions required, or the impact on timeline states. This is insufficient for a mutation-like 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?
The description is a single short sentence, which is efficient but under-specified for a tool with 3 parameters and no annotations. It sacrifices completeness for brevity.
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 3 parameters, no output schema, and no annotations, the description is incomplete. It does not explain return values, behavior during sync, or error conditions. More detail is needed for a tool managing playback synchronization.
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 low (33%), yet the description adds no parameter details. It does not explain 'stagger', 'syncMode', or 'timelineIds' beyond what the schema provides. The description should compensate for missing schema descriptions but does not.
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 '同步播放多个时间轴' clearly states the action: synchronizing playback across multiple timelines. This distinguishes it from sibling tools like 'create_sync_timeline' which creates sync timelines, and 'parallel_animation' which handles parallel execution but not playback sync.
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 multiple timelines need synchronized playback, but it lacks explicit guidance on when to use this tool over alternatives like 'sequence_animation' or 'parallel_animation'. No exclusions or prerequisites are stated.
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 provided, the description carries the full burden but only broadly mentions checking syntax, performance, and match results. It does not disclose side effects, error behavior, rate limits, or prerequisites, leaving significant gaps for the agent.
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 structure. It does not use bullet points or separate sections to highlight different aspects of validation, making it less scannable.
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 tool has 3 parameters and no output schema or annotations, a one-sentence description is insufficient. The agent lacks details about what the validation returns, how to interpret results, or what the optional parameters control.
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 only 33% (only 'selector' parameter has a description). The tool description does not elaborate on the other two parameters ('suggestions', 'performanceCheck'), failing to compensate for the low coverage.
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 validates CSS selectors in terms of syntax, performance, and match results. It uses a specific verb ('validate') and resource ('CSS selector'), and is well-differentiated from sibling tools which are mostly about animations.
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 only implies usage for CSS selector validation, but does not mention when not to use it or suggest related tools like browser compatibility checkers.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
