OfficialServer Quality Checklist
Latest release: v0.25.0
- Disambiguation2/5
Many tools have overlapping purposes, e.g., analyze_component_library, analyze_design_references, fetch_design_inspiration all extract design patterns; forge_assess, assess_legacy_codebase, forge_scan all assess code quality. Agents may struggle to select the correct tool.
Naming Consistency2/5Tool names use inconsistent prefixes: analyze, assess, audit, fetch, figma, forge, generate, get, image_to, list, manage, payments, refine, scaffold, setup, submit, update, validate. No single verb_noun pattern is followed throughout.
Tool Count2/538 tools is excessive for a UI-focused server. Many tools could be consolidated (e.g., multiple generate_* and forge_* tools) or split into separate servers. The scope seems too broad.
Completeness3/5Covers analysis, generation, design, accessibility, migration, Figma, project context, and feedback, but lacks tools for deployment, user management, project creation, and design token CRUD. The payments_refund stub is an odd inclusion.
Average 3.5/5 across 38 of 38 tools scored. Lowest: 2.9/5.

How is the quality score calculated?
The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).
Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.
Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).
Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.
Tool Scores
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must fully disclose behavior. It only states extraction of visual metadata but does not mention error handling, rate limits, or state modification (likely read-only but not explicit).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, concise and front-loaded with key information. No redundancy, but could be improved by separating into multiple sentences for readability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, so description should mention return format; it does not. However, for a simple extraction tool with 3 params and no nested objects, the description is adequate but not fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema covers all 3 parameters with descriptions. Description adds context by listing extracted types (colors, typography, layout hints), which maps to boolean parameters but does not explain interactions or defaults beyond schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states it extracts visual metadata (colors, typography, layout hints) from any URL, specifying verb and resource. It distinguishes from siblings like analyze_component_library and analyze_design_references by focusing on URL-based extraction, though it does not explicitly differentiate.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives, no prerequisites or limitations mentioned. Agent must infer usage from context alone.
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 convey behavioral traits. It states 'Generate components' but does not clarify side effects like file creation, overwriting behavior, required permissions, or whether the tool is idempotent. The description lacks essential safety and impact information.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single 22-word sentence that efficiently conveys the tool's main purpose and capabilities. It is front-loaded and contains no unnecessary words or repetition. Every clause adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 8 parameters (with 3 required) and no output schema or annotations, the description is too brief. It does not explain the output format, file structure, or the role of the nested 'customizations' object. For a tool generating multiple files, the description should provide more context about the generation process and expected results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description mentions themes, custom props, test/story generation, and framework output, which map to parameters (theme, customizations, includeTests, includeStories, framework). However, it does not add significant new meaning beyond the schema's own descriptions; it merely summarizes a subset of parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states that the tool generates components from specific libraries (shadcn, radix, headlessui, material) and lists key features (themes, custom props, tests, stories, framework output). It distinguishes the tool from siblings like generate_ui_component by specifying the library sources, though it could explicitly contrast with similar tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description offers no guidance on when to use this tool versus alternatives, such as generate_ui_component or generate_form. It does not provide any prerequisites, limitations, or exclusions (e.g., when not to use it). The usage context is only implied by the library-specific focus.
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 present, so the description must fully convey behavioral traits. It does not disclose any side effects, constraints, or what happens during generation (e.g., file creation, overwriting, time cost). 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.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that directly states the action. It is front-loaded and efficient, though it could benefit from additional context without becoming verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool generating a full multi-page application, the description is too minimal. It does not explain what a template pack is, how to choose one, or what the output entails. Given many sibling tools, more context on when to use this is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The tool description does not add parameter details beyond schema, but schema already provides adequate descriptions for pack_id, framework, and project_name. No extra value from description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: generate a full multi-page application from a template pack. The verb 'generate' and resource 'multi-page application' are specific, and it distinguishes from siblings like generate_ui_component or generate_page_template.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like generate_page_template or scaffolder methods. There are no usage context, exclusions, or prerequisites mentioned.
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, what the return value looks like, or any side effects. The simple verb 'get' implies read-only, but this is not explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, clear sentence that efficiently conveys the tool's purpose. It is front-loaded with the key information, though additional context could be added without harming conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema and a minimal description, the agent has limited understanding of what 'setup status' entails (e.g., installed libraries, configuration checks). The description does not complete the picture for a tool that likely returns structured data.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 100% coverage for the single parameter 'projectPath', so the schema already defines it well. The description adds no additional meaning beyond the schema, meeting the baseline expectation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('get') and the resource ('component library setup status'), matching the tool name. However, it does not distinguish this tool from siblings like 'analyze_component_library' or 'validate_component_library_setup', which may have overlapping functionality.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives such as 'setup_component_library' or 'validate_component_library_setup'. The description does not mention preconditions, context, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavior. It does not specify if the tool modifies existing files, creates a new project directory, or if it is destructive. It mentions 'config files, dependencies, and initial components' but omits side effects like overwriting or npm install behavior (though a skipInstall parameter exists).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, focused sentence that front-loads key purpose. It is concise, though a slightly more structured format (e.g., listing what it includes) could improve clarity for a tool with 10 parameters.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (10 parameters, no output schema, no annotations), the description is incomplete. It does not explain the outcome (e.g., what is created, path structure), nor does it address when to use it in a workflow. Sibling tools like 'validate_component_library_setup' hint at missing context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the schema already documents all 10 parameters. The description lists example libraries but does not add meaning beyond what's in the schema, such as explaining complex parameters like 'patterns' or 'customizations'. Thus, it meets baseline 3 without additional value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Set up' and the resource 'complete project with a component library', listing specific libraries as examples. However, it does not explicitly differentiate from the sibling tool 'generate_component_library', which could be similar.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives, such as 'generate_component_library'. It lacks prerequisites, context (e.g., new vs. existing project), and exclusions, leaving ambiguity for the agent.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full behavioral disclosure burden. It only states the general purpose but does not describe what happens on success/failure, side effects, or return format. This is insufficient for a validation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence with no extraneous words. However, it lacks behavioral details, but the score for conciseness alone is high.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool performs validation but the description does not explain what 'correctly configured' means, what checks are performed, or how results are returned. Given no output schema, this is insufficient for complete understanding.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents both parameters adequately. The description adds no additional parameter meaning beyond what is in the schema, earning a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Validate' and the resource 'component library is correctly configured in a project directory.' It distinguishes from siblings like 'analyze_component_library' and 'setup_component_library', though not explicitly, so it's a 4.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives. There is no mention of prerequisites, context, or exclusions, leaving the agent without decision-making support.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavior. It indicates the tool runs a check and returns results, but does not mention side effects, authentication requirements, or whether it modifies state. The description implies a read-only operation but does not confirm safety.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, with two sentences front-loading the core purpose. Every word adds value, and there is no extraneous information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers what the tool does and what it returns (status, score, grade, violations), which is adequate given moderate complexity. However, it lacks details on error conditions, required permissions, or output format, and no output schema is provided to fill the gap.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, and the schema already provides meaningful descriptions for each parameter (e.g., threshold overrides config, phase lists allowed values). The description adds 'Configurable threshold and governance phase' but does not provide additional semantic enrichment beyond restating the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool runs a quality gate check on a project and specifies the return values (pass/fail, score, grade, blocking violations). It is specific about the resource ('project') and action, and while it does not explicitly differentiate from siblings like forge_assess, the function is distinct enough.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance is given on when to use this tool versus alternatives like forge_assess or forge_scan. The description mentions configurability (threshold, phase) but does not state when it is appropriate to invoke or when to avoid it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description must fully disclose behavior. It states it generates a plan combining multiple assessments but does not clarify if the tool is read-only, what side effects exist, or required permissions. The absence of behavioral context is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that front-loads the core purpose. While it is efficient and clear, it could benefit from slight restructuring for readability, but overall it is well-prioritized.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (generating a migration plan with multiple components), the description omits return format details and prerequisites. No output schema exists, so the description should explain what the agent can expect as output. This incompleteness limits the agent's ability to use the tool effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% and both parameters ('directory' and 'max_files') are self-explanatory from their schema descriptions. The tool description adds no additional semantic meaning beyond what the schema provides, meeting the baseline expectation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's verb ('Generate') and resource ('full migration plan'), and lists specific components (health assessment, strategy recommendation, etc.), distinguishing it from sibling tools like forge_assess and generate_migration_plan.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., forge_assess, generate_migration_plan). The description lacks context for selection, leaving the agent without direction on prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must disclose behavioral traits. It mentions generating various components but does not address potential side effects such as file overwriting, required permissions, or whether it creates or updates resources. The description is too vague for a generation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that front-loads the core purpose. It is concise but could be slightly more streamlined. No wasted words, but it does not earn extra points for structure beyond being clear.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (5 parameters, no output schema, no annotations), the description does not fully equip an agent. It lacks details on expected output, parameter interdependencies, and when to choose different framework or patterns. Incomplete for a generation tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds minimal value beyond the schema; it lists what is generated but does not elaborate on parameter choices or constraints. The schema already defines the parameters adequately.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it generates a complete backend feature module with multiple specific components (routes, service layer, etc.) following clean architecture patterns. This distinguishes it from siblings like generate_api_route or generate_ui_component.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide any guidance on when to use this tool versus alternatives like scaffold_backend or generate_api_route. No explicit when-to-use or when-not-to-use information is given.
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 all behavioral traits. It mentions the multi-step process but does not state whether the tool is read-only, how long it may take, what side effects occur, or what the output format is. The mention of quality gates lacks detail on what triggers them.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core purpose. It is concise with no wasted words, though a more structured format (e.g., bullet points) could improve readability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (multi-step analysis without output schema), the description lacks important details: output format, duration, prerequisites, and whether it modifies the codebase. It does not reference sibling tools that might be prerequisites or alternatives.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description does not add meaningful extra semantics beyond the schema; 'target_framework' is briefly mentioned but not elaborated, and no examples or constraints are provided.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: generating a phased migration plan. It specifies the steps (runs assessment, detects strategy, produces roadmap with quality gates), which clearly distinguishes it from sibling tools like 'assess_legacy_codebase' or 'forge_migrate'.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, such as whether 'assess_legacy_codebase' should be run first, or when to prefer 'forge_migrate' over this tool.
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?
Given no annotations, description provides minimal behavioral context. It does not disclose rate limits, cost, output format details (e.g., URL vs base64), or error handling. The lack of annotations places full burden on description, which 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.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences, front-loaded with the primary action and resource, followed by a list of supported modes. Every word contributes meaning; no fluff or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool lacks an output schema and the description does not explain what is returned (e.g., image URL, binary data, base64). With 7 parameters and no output details, the agent needs more context to fully understand the tool's behavior and integrate it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. Description adds no parameter-specific information beyond the schema, which already includes clear descriptions for each parameter. No further semantic clarification is provided.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it generates SVG or PNG mockup images of UI screens and components, identifying specific modes (wireframe, mockup, component_preview). This effectively distinguishes it from sibling tools like generate_ui_component which likely produce code rather than images.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit guidance on when to use this tool versus alternatives such as generate_ui_component or image_to_component. The description does not mention scenarios where image generation is preferred over code generation, nor does it indicate prerequisites or limitations.
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 states output is a standalone HTML file but does not mention side effects, auth requirements, rate limits, or what happens to existing data. Lacks transparency typical for a generation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two sentences with no filler. First sentence states core action and scope, second sentence specifies output format. Efficient and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (nested objects, recursive schema, 5 parameters) and no output schema, the description is too sparse. It omits how return values are structured, error handling, or usage patterns beyond the basic output format.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description does not add additional parameter meanings beyond the schema, but the schema already provides sufficient detail for parameters like screens, navigation_flow, etc.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Create') and resource ('interactive HTML prototypes') with clear context ('screen flows, navigation, and transitions'). It differentiates from siblings like generate_ui_component or generate_page_template by focusing on full prototypes with navigation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus siblings like generate_component_library or generate_form. The description does not state prerequisites, when not to use, or recommend alternatives.
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 mentions learning preferences but omits behavioral traits like idempotency, mutations, permissions, or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is two concise sentences, front-loading the action and purpose without unnecessary words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 8 parameters, no output schema, and no annotations, the description does not cover return values, confirmation, or what happens after submission, leaving the agent underinformed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, baseline is 3. The description adds no additional meaning beyond the schema; it does not explain the rating scale context or feedback_type in more detail.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Submit feedback' and specifies the resource as 'previously generated UI component or page template', which is distinct from sibling tools like 'refine_component'. It also explains the purpose of learning preferences.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage after generation but provides no explicit when-to-use, when-not-to-use, or alternatives. With 8 siblings, lack of differentiation is a problem.
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 mentions 'updates the shared design context' which suggests a side effect, but does not clarify the nature of the update (e.g., destructive, reversible), authentication requirements, or rate limits. The behavior is only partially disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence of 16 words with no wasted content. It is front-loaded with the primary action 'Read' and efficiently conveys all key aspects of the tool's function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity, the description covers the main purpose but omits important details such as the return value (since no output schema exists) and the exact implications of 'updates the shared design context'. An AI agent would need to infer what is returned or how the update affects state.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Generate') and resource ('complete production-ready backend project scaffold'), and lists supported frameworks and features, clearly distinguishing it from sibling tools like generate_backend_module or generate_api_route.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not explicitly state when to use this tool versus alternatives. While it implies use for new projects, it lacks guidance on prerequisites, when not to use it, or how it compares to sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions 'Creates or updates variable collections,' which gives some behavioral insight, but lacks details on whether the operation is destructive, required authentication, rate limits, or effects on existing data. The description is clear but minimally transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that efficiently conveys the tool's action and scope. There is no extraneous information, and every word serves a purpose. It is front-loaded with the key verb and noun.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the moderate complexity of pushing variables and the absence of an output schema, the description could be more complete. It does not mention the return value, error conditions, or any prerequisites like authentication. While it covers the core action, it lacks additional context that would help an agent use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, and the schema already describes each parameter adequately (file_key and variables with their types and formats). The description does not add additional semantic meaning beyond the schema, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: writing design tokens back to Figma as variables. It uses a specific verb ('Write') and resource ('design tokens... as Variables') and distinguishes from siblings like figma_context_parser, which reads context rather than modifies. There is no confusion about what this 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 Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for pushing design tokens to Figma, but it does not explicitly state when to use this tool versus alternatives (e.g., when to use figma_context_parser instead). There is no guidance on prerequisites or exclusions, relying on the user's context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. The description implies a read-only operation but does not explicitly state behavioral traits such as side effects, authentication needs, or performance implications. Adequate for a simple list, but could be more explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence of 10 words, no redundancy. Every word is necessary and informative. Excellent conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters and no output schema, the description is minimal. It does not specify output format, ordering, or what 'available' means. Could be improved by mentioning that results are static or filtered by context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist, so schema coverage is 100%. The description adds value by explaining that results include component counts and descriptions, beyond what the empty schema provides. 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.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'list', resource 'component libraries', and specifies that component counts and descriptions are included. It distinguishes from siblings like 'get_available_components' by focusing on libraries.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like 'get_available_components' or 'analyze_component_library'. The description lacks context about prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the transparency burden. It discloses browser automation and screenshot behavior for URLs, and lists extraction outputs. However, it omits potential costs (e.g., processing time), return format, and full lifecycle implications (e.g., global context update). Partial but adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences that are front-loaded: first defines core function, second adds cross-reference analysis. No redundancy, every word adds value. Excellent structure.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 4 parameters (all optional), nested objects, and no output schema, the description covers core extraction and cross-reference logic. Missing output format and global context behavior, but still mostly complete given the complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds context (e.g., 'browser automation + screenshots' for URLs) but does not significantly enhance understanding beyond individual parameter descriptions. No extra syntax or format details provided.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool analyzes design references from URLs and/or images, extracting specific design elements (colors, typography, layout patterns, UI components). It also mentions identifying common patterns across multiple references, providing a specific verb and resource that distinguishes it from sibling tools like analyze_component_library or fetch_design_inspiration.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use cases (analyzing design references) but does not explicitly state when to use this tool versus alternatives. It lacks exclusions or sister tool references, leaving the agent to infer context despite sibling tools existing.
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 fully disclose behavioral traits. It describes the core transformation but omits important details such as data handling policies (is the image stored or discarded?), rate limits, required permissions, or whether the operation is idempotent. This lack of transparency could lead to misuse.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise at two sentences. The first sentence front-loads the main purpose with a strong verb ('Convert'), and the second complements with supported options. Every word earns its place, and no redundant information is present.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the 7 parameters, full schema coverage, and no output schema, the description adequately explains the input requirements and outputs (component code). It covers framework and library options. However, it lacks behavioral context (e.g., error handling, limitations on image size) that would make it fully complete for an agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema provides 100% coverage with descriptions for all 7 parameters, so the description does not need to add much. It does clarify the optional nature of component_library and mentions supported frameworks, but these are already present in the schema enums. The description adds marginal value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it converts images into framework-specific component code, listing supported frameworks and optional UI libraries. It distinguishes itself from sibling tools like analyze_design_image_for_training (which analyzes images for training) and generate_ui_component (which likely does not take image input).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description indicates when to use the tool (when you have a screenshot, mockup, or wireframe to convert). However, it does not explicitly state when not to use it or mention alternatives among the many sibling tools, such as generate_ui_component for text-based generation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It lists what is analyzed and returned, but does not disclose side effects, permissions, performance implications, or non-destructive nature. For a read-like tool, more explicit behavioral context would help.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences efficiently convey the purpose, analysis domains, and return values. No unnecessary words or repetition. Front-loaded with verb and resource.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and one input parameter, the description covers purpose, input, and output fairly completely. Could mention prerequisites or output format details, but for a simple tool it is adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter project_dir is described as 'Absolute path to the project directory to assess', which aligns well with the tool's purpose. Schema description coverage is 100%, and the tool description adds context about it being a legacy codebase.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool assesses legacy codebase for migration readiness, with specific analysis areas and returns. It distinguishes from sibling tools like forge_assess and analyze_component_library by focusing exclusively on legacy codebase migration assessment.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention alternatives among sibling tools. Use is implied for assessing legacy codebase migration readiness, but no exclusions are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fully relies on text to convey behavior. It clearly states the tool performs an audit (non-destructive) and returns issues with severity, suggestions, and WCAG references. However, it does not mention potential side effects (e.g., network calls for criteria references) or resource usage, which would push it to a 5.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is three sentences: first states the core purpose, second lists specific checks, third explains the output. Every sentence adds distinct value without redundancy. The structure is clean and front-loaded, making it easy for an AI agent to quickly grasp the tool's functionality.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description adequately covers the tool's inputs (component code, framework, strict mode) and outputs (issues with severity and references). It lists a broad set of checks but includes 'and more,' which is vague. No output schema exists, but the description compensates by outlining the return format. For a tool with no output schema, this is reasonably complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% with well-defined parameter descriptions (e.g., component_code, framework, strict). The description adds no additional semantic value beyond the schema; it rephrases the overall audit scope without detailing specific parameter usage or interdependencies. Baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly specifies the tool's purpose: auditing a component for WCAG 2.1 accessibility violations. It lists specific checks (e.g., color contrast, ARIA attributes) and describes the output format (issues with severity, suggestions, criteria references). This distinguishes it from sibling tools like analyze_component_library or assess_legacy_codebase, which serve different analytical functions.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies the tool should be used for accessibility audits but provides no explicit guidance on when to use it versus alternatives like analyze_component_library or image_to_component. No exclusions or use cases are mentioned, leaving the agent to infer the appropriate context based on the tool's name and description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses that the tool applies fixes and upgrades, and mentions 'Iteratively improve', implying multiple rounds. However, it does not explain the output format, whether changes are saved directly, or any side effects like code overwriting. The behavioral disclosure is adequate but not thorough.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Three sentences, each adding value: first sentence states purpose, second lists capabilities, third asserts framework support. No redundancy, front-loaded purpose. Ideal length for quick understanding.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no annotations, the description covers the tool's purpose and capabilities well. Missing details: return value description, constraints (e.g., code size limits), and clarification of 'iteratively' (whether multiple calls are needed). Still, it's largely complete for a refinement tool with well-named parameters.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so baseline is 3. The description adds limited extra meaning beyond the schema: it groups feedback examples and mentions 'supports all frameworks' which aligns with the framework enum. It does not offer deep parameter semantics or usage tips beyond what the schema already provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states 'Iteratively improve an existing component' using a strong verb and specific resource. It lists concrete improvement types (accessibility, dark mode, responsive, library upgrades) and notes framework support, differentiating from sibling tools like generate_ui_component which create new components.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Description provides examples of when to use (feedback like 'make it more responsive') and states it supports all frameworks. However, it does not explicitly mention when not to use this tool or suggest alternatives like generate_ui_component for creating new components from scratch.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses that images are not stored and that it's privacy-friendly and zero-cost, which are key behavioral traits. However, it does not explicitly state whether the operation is read-only or non-destructive beyond the storage claim.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences with no wasted words. The first sentence states the core purpose, the second adds critical behavioral context. Information is front-loaded and easy to parse.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description provides a reasonable summary of what is extracted. Given the tool's complexity (5 parameters) and sibling tools, the description is adequate but could be slightly more detailed about return format or error cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so baseline is 3. The description adds value by summarizing the output (colors, typography, components, layout) and privacy aspects, which are not in the schema. This helps the agent understand the purpose of the parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Analyze' and the resource 'UI design image', with specific extraction goals for ML training. It also distinguishes from siblings by noting that it does not store images.
