Server Quality Checklist

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

Latest release: v0.12.0
Disambiguation5/5
Each tool has a clearly distinct purpose. Even similar tools like wpf_find_elements and wpf_find_elements_deep are differentiated by result limits. Descriptions specify exact behaviors and modes (e.g., screenshot modes, click types), leaving no ambiguity.
Naming Consistency5/5
All tools follow a consistent 'wpf_verb_noun' pattern with snake_case. Verbs are imperative (click, set, get, list, find) and nouns describe the target (element, screenshot, property). No mixed conventions or irregular names.
Tool Count5/5
26 tools is well-scoped for a comprehensive WPF debugging server. The set covers attachment, traversal, property inspection, live editing, screenshot, diff, and waiting, without being excessive or redundant.
Completeness5/5
The tool surface is exhaustive for WPF UI inspection and modification: attach, process list, find elements (shallow/deep), get properties/styles/bindings/datacontext/resources, edit live (set property, set text, revert), interact (click, select, send keys), capture screenshots, snapshot/diff, wait for elements, highlight, and watch properties and binding errors.
Average 3.7/5 across 26 of 26 tools scored. Lowest: 2.2/5.

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 exist, so the description must fully disclose behavior. It only says 'Monitor a property for changes' without stating if it blocks, returns immediately, is continuous, or has side effects. This is insufficient for an agent to predict tool impact.
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 at 4 words, but at the expense of critical information. Conciseness should not sacrifice completeness; this is under-specification, not efficient brevity.
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 no output schema, no annotations, and only two bare parameters, the description is severely incomplete. A tool that monitors properties requires details on return format, duration, error handling, and interaction with the UI thread—none provided.
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?
With 0% schema coverage, the description should add meaning to parameters. Neither 'property_name' nor 'element_handle' are explained beyond their names. No hints on format, constraints, or relationship between parameters.
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 uses verb 'Monitor' and resource 'property', indicating a watching function. However, 'monitor' is vague—does it set up a subscription, poll, or return on change? It distinguishes from siblings like 'wpf_get_element_properties' (snapshot) and 'wpf_set_property' (mutation), but the lack of specificity reduces clarity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives like 'wpf_get_element_properties' for one-time retrieval or 'wpf_get_bindings' for binding info. The description does not explain context, prerequisites, or when not to use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No behavioral traits disclosed beyond the action. No annotations provided, so description should cover safety, auth, or side effects, but it does not. Unclear if operation is read-only or modifies state.
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 short (one sentence) but omits critical details. Not effectively concise; would benefit from clarifying parameters and output format.
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?
Very incomplete. No output schema, no parameter documentation, no annotations. Agent lacks information to invoke tool correctly (valid format values, element_handle usage, return format).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%. Description does not explain the format parameter's valid values (only suggests XAML/JSON) or the element_handle parameter's purpose (e.g., root element handle). No default values clarified.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the action (Export) and resource (visual tree) with format options (XAML or JSON). It distinguishes from sibling tool wpf_get_visual_tree by implying file/string output, but could specify whether output is to file or returned.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives like wpf_get_visual_tree. No 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must fully disclose behavior. It does not state that this is a read-only operation or what 'all dependency properties' entails (e.g., attached properties, inherited values). The lack of detail leaves the agent uncertain about side effects or scope.
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 concise at one sentence, but it is underspecified rather than efficiently informative. It earns its place but fails to add necessary detail.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with one parameter and no output schema, the description should still provide enough to use it correctly. It is incomplete because it omits parameter guidance and return value expectations.
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?
The schema has 0% description coverage for the single required parameter 'element_handle'. The description does not explain what a valid handle is, how to obtain it, or its expected format. This is a critical gap for correct invocation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'Get all dependency properties of a UI element', which is a clear verb+resource pair. However, it does not differentiate from sibling tools like 'wpf_get_bindings' or 'wpf_get_data_context', which may cause confusion about scope.
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. There is no mention of prerequisites, such as needing to attach to a WPF application first, or when other property-related tools might be more appropriate.
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?
The description implies a read-only operation ('Get'), but with no annotations and no explicit statement about side effects, permissions, or state requirements, it fails to clarify behavioral traits. A simple read-only hint is absent.
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 (no sections for usage, parameters, or output). While not verbose, 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?
With one parameter, no output schema, and many sibling tools, the description is insufficient. It does not explain what 'layout information' includes beyond examples, nor does it clarify that the output is likely a dictionary of properties. The agent would struggle to use it 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?
The schema has 0% description coverage for the only parameter (element_handle), and the tool description does not add any meaning to what this parameter represents or how to obtain it. The parameter is completely opaque.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: retrieving layout information (ActualWidth, ActualHeight, Margin, etc.) for a WPF element. The verb 'Get' and the specific properties differentiate it from sibling tools like wpf_get_element_properties, though it doesn't explicitly contrast them.
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 like wpf_get_element_properties or wpf_get_data_context. There are no examples 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?
The description only states the basic action without any behavioral details. It does not mention that the highlight is temporary, that duration_ms controls the time, or any other effects. With no annotations, this leaves the agent guessing about the tool's 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.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very short and to the point, but it lacks structure. It is a single sentence without breaking down purpose, parameters, or behavior. While concise, it sacrifices clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is incomplete for an agent to use confidently. It lacks information about the preconditions (element must exist), the effect on UI state, and how the duration works. With no annotations or output schema, the description carries full responsibility for completeness.
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?
The description does not mention or explain any parameters. With 0% schema coverage, the agent has no information about 'element_handle' or 'duration_ms' beyond their types. The description should have clarified these.
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 uses a specific verb 'highlight' and resource 'element', making the purpose clear. While it doesn't explicitly distinguish from siblings, the action is unique among the listed tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No usage guidelines provided. The description does not indicate when to use this tool versus other element-related tools like wpf_click_element or wpf_find_elements.
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 side effects and behavior. It only states enumeration, lacking details on whether this is read-only, impacts state, or what happens with different scope values.
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 without fluff, but it omits critical details, making it under-specified rather than optimally concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given two parameters, no output schema, and a complex domain (WPF resources), the description is incomplete. It does not explain return values, parameter roles, or usage scenarios.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% and description fails to explain the two parameters ('scope' and 'element_handle'). Their purpose, allowed values, and defaults are not clarified, providing no additional meaning.
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 'Enumerate resource dictionaries and their contents' clearly states the action and resource, distinguishing it from sibling tools like wpf_get_styles which focus on specific resource types.
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 like wpf_get_styles or wpf_get_bindings. The description does not mention context or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose behavioral traits. It only states the action without mentioning side effects, data freshness, or requirements, leaving significant gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence is concise but overly sparse; it states purpose adequately but omits necessary details, making it minimally acceptable in structure.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and simple parameters, the description should explain return value or style format. It provides no such context, making it incomplete for effective tool use.
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%, yet the description adds no meaning to the single parameter 'element_handle' beyond the schema, failing to explain its format or scope.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'Get', resource 'applied styles and templates', and target 'element', distinguishing it from sibling get tools like get_bindings or get_element_properties.
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 limitations. The description is silent on usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description carries full burden. It implies a read operation and mentions 'status', but lacks details on output format, potential size, or performance impact. Not contradictory but minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence conveying the core functionality with no waste; front-loaded information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple 1-param tool with no output schema or annotations, the description tells what it does but not what the output looks like or how to use the parameter, leaving gaps.
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 only parameter 'element_handle' is not described in the schema (0% coverage) and the description does not explain how to obtain or format it, leaving ambiguity.
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 verb 'get', the resource 'data bindings', and specifies 'for an element' and 'with their status', distinguishing it from siblings like wpf_get_binding_errors and wpf_get_data_context.
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, prerequisites (e.g., element must exist), or conditions under which it should not be used.
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 behavior. It mentions auto_inject for injecting the Inspector but does not disclose side effects on the target process, error conditions, or prerequisites (e.g., administrator rights, Inspector installation). The description lacks sufficient behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description consists of two sentences: the first states the core purpose, and the second adds essential parameter guidance. It is front-loaded, concise, and contains no filler content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the three parameters and no output schema, the description covers the main action and parameter semantics but does not address what happens after attachment (e.g., return value, readiness for other tools). It omits the context that this tool is a prerequisite for most other WPF tools, which would be valuable for the agent.
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?
With 0% schema description coverage, the description clarifies the purpose of process_id and process_name as identification methods and explains auto_inject for injection. However, it does not address scenarios like both identifiers provided, the default behavior of null, or the difference between the two parameters in terms of precedence.
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 action ('Attach'), the target ('WPF application'), and the two identification methods ('process ID or name'). This distinguishes it from sibling tools like wpf_click_element or wpf_capture_screenshot, which operate on an already-attached application.
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 provides guidance on when to set auto_inject=true, but does not explain when this tool should be used versus alternatives (e.g., wpf_list_processes as a prerequisite). No explicit when-not-to-use or context for choosing between process_id and process_name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description only states basic listing without disclosing details like output format, performance implications, 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence, concise and front-loaded with verb and resource, no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Description covers the basic purpose but omits output format or how it integrates with sibling tools. Given no output schema, more detail on return value would be beneficial.
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?
No parameters, so schema coverage is trivially 100%. Description adds no parameter info beyond schema, but none is needed. Baseline of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states verb 'list' and resource 'running WPF applications', distinguishing it from sibling tools that perform actions like attaching or clicking.
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?
No explicit guidance on when to use vs alternatives, but the purpose implies usage before attaching or inspecting applications. Lacks explicit exclusions.
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 explains filter combination (AND), text matching behavior (case-insensitive substring), property_filter format, visible_only recommendation, and result fields. It does not mention side effects or error handling, but for a read-only query tool, this is sufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is moderately long but front-loaded with the core purpose. It efficiently packs filter behavior, result fields, and a recommendation. Minor redundancy, but no wasted sentences.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 7 parameters, no output schema, and no annotations, the description is fairly complete covering filter behavior, result fields, and a recommendation. Missing root_handle parameter and potential error conditions, but overall adequate for the complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must explain parameters. It covers 6 of 7 parameters (missing root_handle) with useful details like text being visible content, property_filter structure. The missing root_handle is a gap, but overall adds significant meaning beyond the schema.
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?
Clearly states the tool queries elements across all open windows, with filtering details. However, it does not explicitly distinguish from the sibling 'wpf_find_elements_deep' or other tree tools, though it offers a usage preference note.
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?
Provides an example and a preference for using 'text' over dumping the tree, but lacks explicit when-to-use or when-not-to-use guidance relative to alternatives like wpf_find_elements_deep. The guidance is implicit and incomplete.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, authorization needs, or side effects. Since it's a 'get' operation, it likely does not modify state, but this is not explicitly stated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with two sentences, no redundant words, and the purpose is front-loaded. Each sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema is present, and the description does not explain the return format. Behavioral details are missing, but for a simple hierarchical retrieval, the description is minimally viable.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds meaning to both parameters beyond the schema: root_handle is linked to wpf_find_elements, and max_depth has a suggested range (1-100) with a default of 25. Schema coverage is 0%, so the description compensates well.
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 'Get the visual tree hierarchy' with a specific verb and resource. It distinguishes itself from sibling tools by referencing 'root_handle to start from a specific element (from wpf_find_elements)', indicating its unique purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit guidance on using root_handle and max_depth parameters, including a tip for deep UIs like AvalonDock. It does not explicitly mention when not to use or alternatives, but the context is sufficient for typical usage.
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 full burden. It clearly discloses the output: 'Returns a summary (counts) plus, for each element that changed, the exact properties that changed (from → to), keyed by stable element handle; plus elements added or removed between the two snapshots.' No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, front-loaded with the purpose, and efficiently describes the output structure without superfluous text. Every sentence earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description explains the return value in detail (compensating for no output schema) but lacks parameter semantics. For a 2-parameter tool, this is a notable gap, making it somewhat incomplete for an agent to use correctly without additional 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?
Schema coverage is 0%, so the description must add meaning. It mentions 'before' and 'after' as snapshot names but does not explain their format (e.g., file paths, data content). The description only implies they are snapshots captured with wpf_snapshot, leaving ambiguity for the agent.
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 uses specific verbs and resources: 'Diff two snapshots captured with wpf_snapshot, to measure the effect of a change.' It clearly distinguishes from sibling tools like wpf_snapshot (which captures) and others.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states when to use the tool: 'Use this to verify a planned UI tweak did what you expected' and provides concrete examples. It implies a workflow with wpf_snapshot but does not explicitly mention when not to use it or alternatives.
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 full burden. It discloses that the tool clears a list, implying mutation, but doesn't specify side effects, scope (all errors or filtered), or behavior when list is already empty. This is adequate but leaves gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two efficient sentences, front-loaded with the main action and a use case. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple no-parameter tool with no output schema, the description covers the essential purpose and usage context. Could clarify scope, but complete enough for basic tool operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters and 100% schema description coverage. With no parameters, the description adds no parameter-specific info, but this is acceptable as the baseline is 4 for 0 params.
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 tool name 'wpf_clear_binding_errors' combined with description 'Clear the captured binding errors list' clearly states the action and resource. It distinguishes itself from sibling 'wpf_get_binding_errors' which captures errors.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description adds 'Useful before testing specific scenarios,' providing clear usage context. However, no explicit when-not-to-use or alternatives are given, but given the tool's simplicity, this is sufficient.
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 full burden. It transparently describes what the tool returns (DataContext with type info, properties, INPC status, inheritance chain). It does not mention side effects, but as a read-only diagnostic tool, that is acceptable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, no redundancy. The first sentence front-loads the action and output, the second adds practical context. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given one parameter, no output schema, and no annotations, the description is fairly complete: it specifies what is included and why. It could mention that the element must be in the visual tree, but overall it covers essentials.
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 0%, requiring description to compensate. The description implies element_handle identifies an element but does not explicitly define the parameter. Context helps, but explicit description is lacking.
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 gets the DataContext for an element, listing included data (type info, properties, INPC status, inheritance chain) and its use case (diagnosing binding path errors). This distinguishes it from siblings like wpf_get_bindings and wpf_get_visual_tree.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states it is 'essential for diagnosing binding path errors,' providing a clear use case. However, it does not specify when not to use this tool or mention alternatives, but the context is strong.
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?
Without annotations, the description carries full burden and discloses key behavioral traits: uses OS keyboard input, brings target window to foreground, and is state-changing. This warns the agent about side effects. It does not cover rate limits or error conditions, but for a keystroke tool, the disclosed behaviors are sufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single paragraph but well-structured: action statement, examples, modifier/key lists, and behavioral note. Every sentence adds value; no redundancy. Perfectly concise for the information conveyed.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema and no real complexity (2 simple params), the description covers all necessary aspects: what keys are accepted, how to target an element, and side effects. Missing return value info is acceptable for a void-action tool. Adequately complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage, so description must compensate. It explains the 'keys' parameter with examples and valid values, and clarifies that element_handle defaults to current focus. This adds significant meaning beyond the schema's type-only definitions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Description clearly states the action ('Send a keyboard shortcut') and the target ('to a WPF element or to whatever currently has keyboard focus'). It provides specific examples and lists valid modifiers and keys, leaving no ambiguity. No sibling tool performs key sending, so it is well-differentiated.
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?
Description explains that element_handle is optional and that without it, keys go to the focused element. Examples illustrate common keyboard shortcuts. However, it does not explicitly state when to prefer this tool over alternatives like wpf_set_text (for typing text) or when not to use it (e.g., for non-WPF elements requiring different automation).
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. It discloses what data is captured (layout metrics, etc.) and the workflow. It does not detail whether the snapshot is deep or shallow, whether overwriting a label is allowed, or any side effects. It is decent but could be more explicit about safety (e.g., it's read-only).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, using three sentences. The first sentence states the core purpose, the second gives workflow context, and the third clarifies parameters. No redundant or filler words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Considering the tool has 3 parameters and no output schema, the description covers the workflow, parameter usage, and return (label and count). It is missing details about label uniqueness and persistence, but overall it provides sufficient context 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.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, so the description must compensate. It explains each parameter: label is for storing, max_depth default 25, element_handle sets subtree root or whole window. This adds meaningful context beyond the schema types.
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 verb 'capture a snapshot' and specifies the resource: an element's subtree with details about what is captured (layout metrics, visibility, alignment, brushes, text). It distinguishes itself from the sibling tool wpf_diff, which compares snapshots, by explaining its role in the workflow.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit guidance on when to use this tool: in a workflow with wpf_snapshot before and after a change, followed by wpf_diff. It explains that element_handle sets the subtree root and max_depth defaults to 25. However, it does not mention when not to use it or alternatives beyond wpf_diff.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided so description bears full burden. It discloses that 'render' re-renders off-screen and cannot see popups/menus, while 'screen' captures on-screen pixels and requires visibility. This is good behavioral disclosure for a screenshot tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences: first states purpose concisely, second provides detailed mode guidance. Efficient but could be slightly more structured with bullet points for clarity. No information is wasted.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema, but description notes it returns an image for visual analysis. Parameters are mostly covered. For a screenshot tool with no complex outputs, this is complete enough for an agent to use correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so description compensates by explaining 'element_handle' (capture specific element or omit for entire window) and 'mode' (render vs screen with behavioral differences). max_width and max_height are not explained beyond defaults, but their purpose is somewhat implied.
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?
Clearly states 'Capture a screenshot of the WPF window or a specific element.' The verb 'capture' and resource 'screenshot of WPF window/element' are specifically defined. No sibling tool performs a similar function, so it is well-differentiated.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit guidance on when to use each mode: 'render' for general use but cannot capture popups/menus; 'screen' for capturing popups/menus after clicking. Also advises to use element_handle for specific elements. Lacks explicit 'when not to use' but is clear enough.
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 carries the full burden for behavioral transparency. It details what the tool reports: value source, effective value, animation/coercion status, and for bindings, a hop-by-hop path resolution. It does not mention side effects, permissions, or error handling, but the disclosed behavior is sufficient for an agent to understand the tool's operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is several sentences but each sentence adds value: first states purpose, then details output, then differentiates from sibling. It is well-structured and front-loaded. Could be slightly more concise, but no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, no output schema, and two parameters with 0% schema coverage, the description provides substantial context about what the tool returns and its diagnostic role. It does not cover return format or error scenarios, but the level of detail is adequate for a diagnostic tool in a rich sibling set.
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 0% (no descriptions in the input schema), so the description must add meaning. While the tool name and description imply that 'element_handle' identifies the UI element and 'property_name' the property, it does not explicitly describe their types, formats, or constraints. The context helps, but explicit parameter explanations would improve clarity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: explain why a property has its current value. It specifies the resource (a property) and the action (evaluate binding). It directly distinguishes itself from sibling tool 'wpf_get_bindings' by noting that it evaluates one binding while the other lists them.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly tells when to use this tool: it is the 'go-to tool for why is X empty/wrong/disabled?' and states it complements 'wpf_get_bindings' by evaluating a specific binding. It provides clear context on when to invoke it versus alternatives.
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 carries the full burden. It discloses key behaviors: no result limit, requirement for at least one filter, and scoping via root_handle. It does not cover return format or performance implications, but the main behavioral aspects are transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, with two sentences that front-load the purpose and requirement, then list filters and scoping. Every sentence adds value, and there is no extraneous text.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool with 6 parameters and no output schema, the description adequately covers input constraints but misses important context: it does not describe the return format (list of elements) or any error conditions. The word 'deep' is used but not defined. These gaps reduce completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must compensate. It explains 5 of 6 parameters (type_name, element_name, text, visible_only, root_handle) with matching semantics. However, 'property_filter' is mentioned but not explained, which is a minor gap. Overall, the description adds substantial meaning beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool performs a deep search for all matching elements with no result limit. It distinguishes itself from the sibling 'wpf_find_elements' by specifying 'no result limit' and indicating the same filters, making the purpose and differentiation explicit.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear usage constraints: requires at least one of type_name, element_name, or text to avoid returning the entire tree. It also mentions using root_handle to limit scope. However, it does not explicitly state when to use an alternative tool (e.g., wpf_find_elements for limited results), though the differentiation is implied.
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?
In absence of annotations, description notes detection via WPF trace listener but does not cover behavior like empty list or performance. Adequate for a simple read-only tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two efficient sentences: first states purpose and scope, second provides guidance. No extraneous content.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given zero parameters and no output schema, the description covers purpose, detection method, and related tool. Complete for this simple tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
No parameters exist; schema coverage is trivially 100%. Baseline 4 for 0-parameter 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?
The description clearly states 'List all binding errors captured since application start' with a specific verb (list) and resource (binding errors), and distinguishes from sibling wpf_clear_binding_errors.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides explicit alternative tool for resetting (wpf_clear_binding_errors) but lacks broader guidance on when to use this vs other get tools like wpf_get_bindings.
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 carries full burden and details behavioral traits: default uses IValueProvider.SetValue (clean, no focus, raises events), fallback to direct property setting, and physical mode's focus, clear, and type behavior. It also declares 'STATE-CHANGING.' Missing details on potential side effects or error conditions, but sufficiently transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is information-dense and front-loaded with the primary purpose. It efficiently covers default behavior, fallbacks, and the physical mode in a readable structure. Some minor redundancy could be trimmed, but overall concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a text-setting tool with no output schema, the description covers the main behaviors, fallback mechanism, and physical typing mode. It does not explain return values or error handling, but given the tool's expected behavior, it provides enough context for an agent to use it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains the 'text' parameter as the value to set, 'physical' as a boolean for OS keyboard input, and 'element_handle' by context as the target element. While element_handle is not explicitly defined, the purpose is clear. The description adds meaning beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool sets text/value of UI elements like TextBox and ComboBox, naming the primary method (IValueProvider.SetValue) and fallbacks. It distinguishes itself from sibling tools focusing on clicking, selecting, or sending keys.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains when to use the default mode vs physical=true (focused typing), providing clear context for choosing between them. However, it does not explicitly contrast with sibling tools like wpf_send_keys or wpf_set_property, leaving some ambiguity about when to prefer this tool over alternatives.
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 full burden. It discloses polling mechanism, condition options, return values (matched bool, waited_ms, matched_handle), and default limits (timeout 10000ms, max 25000ms, poll interval 250ms). Lacks detail on error handling or edge cases like timeout result.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, with about 5 sentences that are front-loaded with purpose. Each sentence adds value, though a slight restructuring could improve clarity. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (polling, multiple conditions, async usage), the description covers usage context, condition semantics, return fields, and defaults. It is nearly complete for typical agent usage, though it could detail the root_handle parameter and timeout behavior.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains the matching parameters (type_name, element_name, text) and condition options, timeout_ms default and max, poll_interval_ms default. It omits explanation for root_handle, but overall adds significant meaning beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: waiting for an element to satisfy a condition via polling. It specifies the verb 'wait' and the resource 'element matching criteria', and distinguishes it from sibling tools like wpf_find_elements by emphasizing the polling behavior.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit when-to-use guidance: 'Use after a click that triggers async work (dialog opens, spinner clears, button enables) before the next step.' It explains each condition and its typical scenario, but does not explicitly state 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.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description fully bears the burden. It discloses side effects: physical click moves cursor, brings window forward, auto-scrolls; double/right clicks are always physical. It also labels the tool as STATE-CHANGING. This is comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is moderately concise; every sentence adds value. It is front-loaded with the core action and structured with parameter details. Minor redundancy could be trimmed, but overall effective.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description does not mention return values or error handling. However, it covers usage modes, parameter details, and behavioral nuances. For a simple click tool, this is mostly complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must explain parameters. It covers physical (boolean, default false), click_type (string, default null, listing 'single', 'double', 'right'), but element_handle is only mentioned as required without further explanation. Slightly incomplete, but valuable.
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 clicks a UI element, enumerates supported control types (buttons, menu items, etc.), and distinguishes two modes (UI Automation vs physical click). This specificity and resource identification earn a 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides explicit when-to-use guidelines: default vs physical click, click types (single, double, right), and after-action tips (use wpf_capture_screenshot for context menus). It lacks explicit when-not-to-use or alternatives, but the guidance is effective.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. Discloses that it is state-changing ('STATE-CHANGING') and describes failure behavior (lists available items). No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Concise with no wasted words. Front-loads purpose, then adds guidelines and behavioral notes. Every sentence earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers control types, selection methods, preference over clicking, virtualized items, selection events, error behavior, and state-changing. Complete for a selection tool without output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. Description adds meaning: explains item_text as visible text with case-insensitive substring matching, index as zero-based. Adds value beyond bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states it selects an item in ComboBox, ListBox, ListView, or TabControl by visible text or zero-based index. Distinguishes from sibling tools like wpf_click_element by noting it works with virtualized items and raises proper selection events.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says 'PREFER this over clicking for dropdowns/lists' and explains why. Does not explicitly state when not to use it or name alternatives, but the preference guidance is clear and actionable.
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 full burden. It discloses that the tool is state-changing, reversible, replaces bindings with local values, and returns coerced value and previous source. It does not mention potential side effects or permissions, but coverage is strong for a testing tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is front-loaded with purpose, followed by examples and behavioral notes. It contains some redundancy (e.g., repeated 'e.g.') but every sentence adds value. Slightly long but well-organized.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of 3 string params and no output schema, the description is exceptionally complete: it covers purpose, usage, parameter details, side effects, return value, and related tools. No critical information is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description compensates fully by explaining each parameter through examples and specifying that value is a string converted to the property's type, including syntax for null and various types.
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 it live-edits a dependency property at runtime for testing UI changes. It provides specific examples and distinguishes from siblings by mentioning pairing with wpf_capture_screenshot and wpf_revert_property.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explains the tool is for testing UI changes without rebuilding, suggests pairing with screenshot and revert, and gives usage examples. However, it does not explicitly state when not to use this tool versus alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fully covers behavioral aspects: it lists triggers, evaluates conditions, shows current values, match status, active status, and setters. It also explains the optional property_name parameter for value attribution. No contradictions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is detailed but each sentence adds value. It is front-loaded with the primary purpose and use cases. Minor redundancy could be trimmed, but overall it is well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, no output schema, and only two parameters, the description is complete: it explains both parameters, the output (list of triggers with evaluation), and the optional behavior when property_name is provided. It covers all necessary information for an AI 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.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has 0% description coverage, so the description adds meaning: element_handle is implied as the target element, and property_name is explained as 'attribute that property's effective value to its source'. This compensates for the lack of schema descriptions.
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 it explains triggers and value sources for WPF elements, with specific use cases like 'why doesn't this trigger fire?' and 'which style/setter set this value?'. It distinguishes itself from sibling tools by focusing on trigger evaluation and property attribution.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides clear use cases for when to use this tool, such as debugging trigger firing and identifying value sources. However, it does not explicitly mention when not to use it or compare it to alternatives like wpf_get_styles or wpf_get_element_properties.
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?
Discloses that it restores the previous property value (binding, local, or fallback) and returns counts of reverted and pending edits. No annotations exist, so description carries full burden; it provides sufficient behavioral insight.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Three sentences efficiently convey purpose, options, and behavior without unnecessary detail.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description covers return values and fallback behavior, making it complete for understanding tool effects.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Description adds meaning to all three parameters (all, property_name, element_handle) beyond the schema's type/default definitions, explaining their roles in targeting and scope.
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?
Clearly states it undoes live property edits made with wpf_set_property, distinguishing it from siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explains default revert of most recent edit, options to target specific edits via element_handle and property_name, and all=true for bulk revert. While clear, it does not explicitly state when not to use this tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
