Server Quality Checklist

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

Latest release: v0.1.0
Disambiguation4/5
Most tools have distinct purposes, but there is some potential confusion between generate/apply campus config tools and between buildCampusRecordingDemo vs. step-by-step add tools. Descriptions help, but overlap exists.
Naming Consistency5/5
All tools use the consistent 'ptv_verb_noun' pattern. Verbs are descriptive and nouns are specific, making the set predictable and easy to navigate.
Tool Count4/5
23 tools is at the upper bound of reasonable for a complex domain like network simulation, but each tool serves a clear purpose for campus topology building, configuration, and validation.
Completeness4/5
The tool set covers core workflows: device addition, linking, configuration, validation, and fault injection. However, removal or update operations are missing, and the focus is heavily on a specific campus demo, which may leave gaps for general use.
Average 3.1/5 across 23 of 23 tools scored. Lowest: 2.3/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should carry more behavioral info. It states 'generation and application' implying configuration changes, but does not disclose potential side effects (e.g., overwriting existing configs), safety, reversibility, or that it may be destructive. Lacks detail on what 'apply' entails.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness2/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is only one sentence, but it is under-specified. It lacks structured details about parameters and behavior. Conciseness should not sacrifice necessary information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (6 params, no output schema, no annotations), the description is far too minimal. It does not explain what the config set contains, the role of each parameter, the generation vs. application process, or expected outcomes. Incomplete for a production tool.
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 provides zero explanation for the 6 parameters. No hints on what prefix, routingProtocol, dhcpMode, etc., control. The agent must guess from names and enums, which is insufficient.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it does 'one-click generation and application of the complete campus IOS configuration set', which is a specific verb and resource. It distinguishes itself from sibling tools like ptv_generateCampusIosConfig (generate only) and ptv_applyIosConfigSet (apply only), but does not explicitly mention these alternatives.
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?
Only mentions a prerequisite (Packet Tracer bridge connection). No guidance on when to use this tool versus siblings, no context on when not to use it, and no mention of typical use cases or 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?
Without annotations, the description must convey behavioral traits. It only mentions sequential creation with a delay, but does not disclose behavior around retries, quality modes, or error handling.
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, concise and front-loaded. However, it sacrifices necessary detail, making it under-specified for a tool with many parameters.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 9 parameters, no annotations, and no output schema, the description is far too minimal. It lacks information on return values, error handling, and parameter configurations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description adds no meaning to any parameter. It only hints at delay without linking to the delayMs parameter or explaining others.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states it creates links sequentially with delay, optimized for recording topology wiring, clearly identifying the verb and resource and distinguishing from a bulk add.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for recording wiring sequences but provides no explicit guidance on when to use this vs. ptv_addLink or other siblings, nor any 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 disclose behavioral traits. It mentions 'generate or apply' but does not explain that applying repair commands may modify network state (destructive), nor does it describe the output format or error conditions.
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 (one sentence), which is efficient but sacrifices clarity. It uses 'or' to cover two modes, but could be more structured to explain the dual behavior.
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 3 parameters with no schema descriptions, no output schema, and no annotations, the description is severely incomplete. It fails to explain the relationship with fault library, the role of prefix, or the result of apply=true.
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?
With 0% schema description coverage, the description adds no meaning to the parameters: faultId (source of fault IDs?), prefix (purpose?), apply (what does true/false mean?). Schema itself also lacks descriptions.
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 generates or applies repair commands for a built-in fault scenario, which distinguishes it from sibling tools like injectFault (injects faults) and getFaultLibrary (lists faults). However, it could be more specific about what 'built-in fault scenario' means.
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 vs alternatives such as ptv_injectFault or ptv_getFaultLibrary. The description does not mention prerequisites, when to generate vs apply, or typical use cases.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must disclose behavioral traits. It only states the operation ('Create one link') without mentioning side effects, error conditions, or behavior of parameters like autoAssignPorts and autoFallback. Minimal disclosure for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single short sentence (11 words), which is appropriate in length but lacks substantive information. It is concise but at the expense of clarity on parameters and behavior.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 7 parameters, no output schema, and no annotations, the description is severely inadequate. It does not cover return values, error handling, or parameter dependencies, leaving the agent with insufficient context to use the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description adds no meaning to any of the 7 parameters. It does not explain the roles of fromDevice, toDevice, fromInterface, toInterface, linkType, autoAssignPorts, or autoFallback. The agent must rely solely on parameter names.
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 ('Create one link'), the resource ('link'), and the context ('between two existing Packet Tracer interfaces'). It distinguishes from siblings like ptv_addDevice or ptv_addDevicesTimeline, which involve adding different entities.
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 (e.g., devices and interfaces must exist). The description implies usage but does not help the agent decide between this and other link-related tools like ptv_addLinksTimeline.
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 lacks disclosure of side effects (e.g., overwriting existing device), authentication requirements, or error conditions. Only states what it does, not behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Single sentence with 10 words, highly concise and front-loaded with key action and object. However, it sacrifices necessary detail.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema and 4 required parameters, description is grossly incomplete. Does not specify return value, error handling, or constraints like coordinate bounds.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% and description adds no meaning beyond parameter names. Does not explain valid model values, coordinate units (pixels? meters?), or naming conventions.
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 'Add', resource 'Packet Tracer device', and specificity 'one at specific workspace coordinate'. Distinguishes from sibling tools like ptv_addDevicesTimeline which adds multiple devices over time.
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 vs alternatives such as ptv_addDevicesTimeline or ptv_addLink. No 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 provided, and the description does not disclose behavioral traits such as whether it overwrites existing config, requires specific permissions, or is destructive. The description is minimal and lacks transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single concise sentence (12 words) that gets straight to the point. It could be slightly more structured, but it is front-loaded and efficient.
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 annotations, no output schema, and the complexity of the tool (applying config to devices), the description is insufficient. It does not explain return values, error handling, immediate effects, or success verification.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, but the description loosely maps to the parameters by mentioning 'deviceName plus commands entries'. However, it does not explain the structure of 'commands' (e.g., valid IOS commands) or that it can be a string or array, missing the opportunity to add value 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?
The description clearly states the verb 'Apply' and the resource 'IOS config set', and specifies that it is composed of 'deviceName plus commands entries'. This distinguishes it from related sibling tools like 'ptv_applyCampusIosConfig' which likely applies a pre-defined config.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives (e.g., 'ptv_applyCampusIosConfig', 'ptv_configureIos'). No mention of prerequisites, limitations, or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of disclosing behavior. It only states it does not touch Packet Tracer, which is a negative behavioral trait. It does not mention whether the tool is read-only, if it requires authentication, or any side effects. This is insufficient for an agent to assess safety.
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 concise (two sentences) and front-loaded with the purpose. However, it is too terse for the complexity of the tool; it omits critical information about parameters and output. Conciseness should not come at the cost of completeness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the lack of output schema and the nested 'params' parameter, the description should explain what the tool returns and how templates are structured. It does neither. The tool is moderately complex (multiple template types) but the description fails to provide complete context for an agent.
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 input schema has 2 parameters (template, params) with 0% schema description coverage. The description lists the template types but does not explain how to use the 'params' object, which is a non-trivial nested parameter. It provides no semantic meaning beyond the schema, leaving the agent to guess what params should contain.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it generates IOS command templates for specific protocols (static routes, RIP, etc.). It also distinguishes itself from siblings by noting it does not touch Packet Tracer, implying it is a template generation tool rather than a configuration application. However, 'generate' could be more explicit about the output format.
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 the exclusion 'does not touch Packet Tracer' which hints at when not to use it, but it does not explicitly state when to use this tool versus alternatives like ptv_configureIos or ptv_applyIosConfigSet. It lacks guidance on prerequisites or context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must cover behavioral traits. Only mentions that commands can be a string or array, but does not disclose execution behavior, side effects, or device state requirements.
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, 14 words, fully front-loaded. No wasted words, efficient for a simple tool.
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 zero schema coverage, no output schema, and no annotations, the description is too sparse. Lacks return value information, error handling, and usage context for a tool with two required parameters.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and description only adds that commands can be a string or array. It does not explain the 'deviceName' parameter or provide additional meaning beyond basic schema information.
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 'send Cisco IOS commands to one router or switch', identifying the verb and resource. It distinguishes from siblings like 'ptv_runShowCommands' but does not explicitly differentiate from 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 Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool versus alternatives like 'ptv_applyCampusIosConfig' or 'ptv_runShowCommands'. Missing 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?
With no annotations provided, the description carries the full burden. It lists possible fault scenarios but does not disclose behavioral traits such as whether the tool modifies network state, requires permissions, or is reversible. The term 'inject' implies some system change, but no explicit disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is concise and front-loaded with the tool's purpose. It includes examples which aid understanding without being verbose. However, it could be restructured to include parameter details without increasing length.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the three parameters, zero schema coverage, no output schema, and no annotations, the description is incomplete. It does not explain how to use the parameters, what the output is, or provide any context about when to inject vs repair faults (sibling tool ptv_repairFault is present).
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% and the description does not explain any of the three parameters (faultId, prefix, apply). The user has no guidance on what values faultId accepts, what prefix does, or what apply=true means. This is a critical gap.
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 specifies the verb 'generate or apply' and the resource 'built-in fault scenario' with concrete examples like missing trunk VLAN, OSPF area mismatch, etc. It clearly differentiates from sibling tool ptv_repairFault, which is for repairing faults.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide any guidance on when to use this tool versus alternatives like ptv_repairFault or when not to use it. The statement is purely functional without context for selection.
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, description must disclose all behavioral traits. It mentions sequential appearance of devices and links, IP application, and optional IOS commands, but omits details on error handling, side effects on existing networks, or behavior of parameters like retries and delays.
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 (two sentences) with no wasted words. It front-loads the action and ends with the intended use. However, the extreme brevity sacrifices parameter explanation and behavioral detail.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (16 parameters, no output schema, no annotations), the description is severely incomplete. It lacks prerequisites, return value information, parameter explanations, and details on what constitutes a valid campus plan.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description does not explain any of the 16 parameters (e.g., prefix, originX, scale, delays). It only gives a high-level summary of actions, failing to add 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?
Description clearly states the tool builds a visually complex campus topology, with specific actions (devices, links, IPs, IOS commands). It distinguishes from sibling tools like ptv_addDevice or ptv_addLink by highlighting it as a composite demo/recording-oriented build.
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 says 'Designed for course-design demos and screen recordings,' implying use for bulk/automated campus builds. However, it does not explicitly state when not to use it (e.g., for step-by-step or non-demo tasks) or name alternatives among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the burden. It only states 'Set' implying mutation, but does not disclose behavioral traits like idempotency, error states, or consequences of setting DHCP alongside IP fields.
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 highly concise with one sentence and no unnecessary words. However, the brevity borders on under-specification, sacrificing some informational value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 6 parameters, no output schema, and no annotations, the description is incomplete. It fails to specify required parameters, behavior when DHCP is true, return values, or error conditions.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description merely lists the parameter names without adding format constraints, relationships (e.g., DHCP vs IP), or default behavior. It does not compensate for the schema's lack of 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 uses the specific verb 'Set' and clearly identifies the resource as 'PC or Server IPv4 address, mask, gateway, DNS, or DHCP flag'. It distinguishes from siblings like ptv_configureIos (for IOS devices) and ptv_addDevice (adding devices).
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 such as ptv_configureIos. There is no discussion of prerequisites, 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?
No annotations are provided, and the description only mentions the default mode and behavior difference for validation modes. It does not disclose whether the tool modifies state, requires permissions, or has side effects, leaving significant behavioral ambiguity.
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 short sentences, front-loading the main action and the most important parameter guidance. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 6 parameters, no output schema, no annotations, and many siblings, the description is insufficient. It fails to explain parameter meanings, output format, or how it fits into the workflow of related tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description only implicitly explains one parameter (validationMode) by mentioning its default and trade-offs. The other five parameters (prefix, routingProtocol, dhcpMode, includeNatPat, includeAcl) are left completely unexplained.
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 'Generate a campus validation plan' with a specific verb and resource. However, it does not differentiate from sibling tools like ptv_validateCampusFast, which may perform a similar function.
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 gives guidance on when to use different validationMode values ('fast' default vs 'standard/strict'), but does not explain when to use this tool compared to other validation or generation tools among the siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, description discloses key trait (read-only, no service changes). But lacks details on permissions, error handling, or response behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

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 3 parameters, no output schema, and no annotations, description is minimally adequate for a read-only probe but lacks parameter details and usage context among 22 sibling tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, and description adds no explanation for deviceName, maxDepth, or maxKeys beyond their names. Meaningful parameter semantics absent.
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?
Explicitly states verb (probe/scan) and resource (Server-PT devices for DNS/HTTP/FTP/DHCP related API names). Distinguishes from sibling ptv_probeDeviceApi by specifying focus on service automation hints and read-only nature.
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 ptv_probeDeviceApi. Only implies read-only probing without exclusions or prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavioral traits. It states 'read' implying no side effects, but lacks details on what happens with an empty deviceName (returns workspace-wide history?), data freshness, or format. Minimal information beyond the basic read action.
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?
A single sentence of 14 words efficiently conveys the core purpose. It is front-loaded, but could be slightly expanded without losing conciseness to cover parameters more explicitly.
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 simple read operation with no output schema and two optional parameters, the description is minimally adequate. However, it lacks details on output format, pagination, or behavior when limit is reached, leaving gaps for an AI 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?
Schema coverage is 0%, so the description should compensate. It partially explains deviceName by mentioning per-device vs workspace, but does not describe the limit parameter's meaning or effect. Adds some meaning but incomplete for a 2-param tool.
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 'read' and the resource 'Packet Tracer command history', with explicit scoping to 'one device or the whole workspace'. This distinguishes it from sibling tools like ptv_runShowCommands or ptv_configureIos, which have different purposes.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites, limitations, or scenarios where other tools (e.g., ptv_probeDeviceApi) 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?
With no annotations provided, the description must fully disclose behavioral traits. It mentions sequential addition with delay and that operations are 'real,' but fails to describe key behaviors such as how failures are handled (retries), the effect of parameters like qualityMode, or whether the operation is atomic. This minimal disclosure is insufficient for safe invocation.
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 two sentences and extremely concise, which is good for readability. However, it lacks structure such as a brief list of key parameters or a note about defaults. For a tool with 9 parameters, slightly more structure would help without sacrificing conciseness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 9 parameters, 0% schema coverage, no output schema, and no annotations, the description is far too brief. It covers the core purpose but omits essential details about parameter effects, error handling, sequencing behavior, and return values. A more complete description is needed for an agent to use this tool effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% parameter description coverage, and the description adds no explanation for any of the 9 parameters (e.g., delayMs, qualityMode, maxRetries). It only indirectly references a 'short delay,' but does not map to the delayMs parameter or other settings. This leaves the agent without guidance for setting correct values.
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 ('Add devices') and resource ('Packet Tracer'), with a specific execution mode ('one by one with a short delay'). It distinguishes itself from sibling 'ptv_addDevice' by indicating batch sequential addition, and specifies the use case ('screen recordings').
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 usage guidance: 'Use for screen recordings where viewers should see devices appear sequentially.' This clarifies the intended context, but it does not mention when to avoid this tool (e.g., when sequential delay is not desired) or explicitly name alternatives like 'ptv_addDevice'.
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 full behavioral disclosure burden. It mentions the tool does not run heavy show commands, indicating it is lightweight, but does not detail side effects, permissions, or whether operations are read-only or mutating.
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 short and front-loaded with the core purpose. It efficiently conveys the key components in two sentences, though a bulleted list could improve scannability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity (8 parameters, nested objects, no output schema), the description is incomplete. It lacks details on return values, parameter effects, and prerequisites, leaving significant gaps for an agent to invoke correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, yet the description provides no parameter explanations. The 8 parameters, including nested objects like plan and buildResult, remain completely opaque, failing to add 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 it runs a 'speed-preserving campus validation' and lists specific components (plan shape, build/apply results, canvas snapshot, key-device/link checks), distinguishing it from siblings like ptv_runShowCommands and ptv_generateCampusValidationPlan.
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 implies usage for fast validation by noting it does not run heavy show commands, providing context for when to choose this tool over heavier alternatives. However, it does not explicitly state when not to use it or name 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?
With no annotations, the description carries full burden. It implies a read-only preview operation ('without touching Packet Tracer') but does not disclose side effects, permissions, or whether the plan is cached or regenerated. 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, front-loaded with the core purpose. No wasted words, efficiently communicates the tool's function.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Despite a clear purpose, the description lacks explanation of parameters and return values (no output schema). For a tool with 4 undocumented parameters, this is insufficient 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.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 4 parameters (prefix, originX, originY, scale) with 0% description coverage. The description adds no meaning to these parameters, leaving the agent to guess their purpose. This is a significant gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool generates a built-in campus-network demo plan for previewing device names, VLANs, links, service steps, and tests. It uses a specific verb ('Generate') and resource ('campus-network demo plan'), and distinguishes from sibling tools that add or configure devices.
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 says 'Use this to preview...' providing clear context for when to use the tool. However, it does not mention when not to use or alternatives among siblings, which is a minor gap.
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; description states 'Read-only probe' indicating non-destructive behavior, but does not disclose error handling, rate limits, or edge cases.
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, front-loaded with key information, no wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 4 parameters, no output schema, and no annotations, the description is incomplete; it lacks parameter explanations, return value or error information.
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 has 0% description coverage and the description does not explain any of the four parameters (deviceName, maxDepth, maxKeys, includeSafeCalls), failing to add 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?
Description clearly states it is a read-only probe for device object APIs, distinct from sibling ptv_probeServerServices which probes server services.
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 states when to use: to inspect device API methods before Server-PT automation. Implicitly not used for other tasks, but lacks explicit alternatives 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?
No annotations are provided, so the description carries the full burden. It discloses a limitation ('Packet Tracer does not guarantee full show-output parsing') and mentions returning a confirmation log, but omits side effects, destructive potential, or permissions. This is adequate but not comprehensive.
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, front-loaded with the key action and outcome. No extraneous words, highly efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
No output schema exists. The description only mentions 'command-log confirmation' without specifics on structure, error handling, or pagination. For a command-issuing tool to a network device, this is insufficient context to understand the full interaction.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%. The description adds context for deviceName and commands ('issue show commands to one IOS device'), but does not explain logLimit (default 120). With 3 parameters, the description only partially compensates for the missing 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 the tool issues show commands to a single IOS device and returns command-log confirmation. It distinguishes from siblings like ptv_configureIos (config commands) and ptv_getCommandLog (retrieve logs), giving a specific verb and resource.
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 implies this tool is for show commands, not configuration, which gives some context. However, it does not explicitly state when not to use it or provide alternatives, missing a clear usage boundary.
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, so description must convey behaviors. It mentions supported features but lacks details on side effects, output format, or prerequisites. It does not say whether it is a read-only operation or modifies state; generation typically returns config but 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, front-loaded sentence that immediately states the purpose and key capabilities. Every phrase adds value, with no redundancy.
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 tool has 6 parameters and no output schema. The description covers main features but does not explain the 'prefix' parameter or the effect of 'writeMemory'. For a generation tool, more detail on the output (e.g., format, how to apply) would be helpful, but sibling tools handle application.
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% and description does not explain any parameter individually. It mentions routingProtocol, DHCP, ACL, and NAT/PAT, which correspond to parameters, but omits 'prefix' and 'writeMemory'. Parameter names are not explained, and defaults are not mentioned.
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 generates a complete IOS configuration set for the built-in campus topology, listing supported routing protocols and features. It distinguishes from sibling tools like ptv_generateIosTemplate or ptv_applyCampusIosConfig by specifying the target topology and completeness.
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 implies usage: when generating a full config for the built-in campus topology with specific routing protocols, DHCP mode, etc. It does not explicitly state when not to use or alternatives, but the context is clear enough.
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, but description correctly implies a read-only check without side effects. However, no further behavioral details (e.g., network call, caching) are disclosed. Sufficient for a simple status check 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 with no waste. Front-loaded with the action and result. Perfectly sized for the tool's trivial nature.
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, description is fully complete. The tool's purpose is simple and no additional context is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5

Tool has zero parameters and schema coverage is 100%. Description adds no parameter info, which is acceptable. Baseline 4 for no-param 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?
Description clearly states the tool checks connection status of Packet Tracer Visual MCP extension. Verb 'Check' and resource 'connection' are specific. No sibling has similar purpose, so differentiation is not needed.
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. It could be used before other operations, but not stated. No exclusions or context provided.
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 full burden. It states the tool returns scenarios with symptoms and commands, but does not disclose potential authentication needs, rate limits, or performance characteristics. The behavior is clear enough for a read-only listing without 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is concise and front-loaded with the main action. Every word contributes to understanding, with no waste.
