Server Quality Checklist

58%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v0.1.0

  • Disambiguation5/5

    Each tool targets a clear and distinct resource and action (e.g., create_application vs. create_device), with no overlapping purposes. Operations like enqueue_downlink are differentiated by target (device vs. multicast group).

    Naming Consistency5/5

    All tools follow a consistent verb_noun snake_case pattern (e.g., list_applications, update_profile, remove_device_from_multicast_group). No mixing of conventions or vague verbs.

    Tool Count4/5

    With 34 tools, the set is on the higher end but justified by the breadth of resources managed (applications, devices, profiles, multicast groups, packets, etc.). Each tool serves a specific purpose without redundancy.

    Completeness4/5

    The tools provide full CRUD for four main resource types plus specialized operations for downlink and multicast management. Minor gaps exist (e.g., no tool for managing service profiles), but the core gateway management workflow is well-covered.

  • Average 3/5 across 34 of 34 tools scored. Lowest: 2.4/5.

How to sync the server with GitHub?

Servers are automatically synced at least once per day, but you can also sync manually at any time to instantly update the server profile.

To manually sync the server, click the "Sync Server" button in the MCP server admin interface.

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 carries the full burden. It only implies destructive action but does not disclose irreversibility, effects on associated data, or authentication requirements.

    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, front-loaded sentence, which is concise. However, it is under-specified for the complexity of the tool, sacrificing 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?

    Without an output schema, the description should explain return values, but it does not. The tool is simple, yet the description lacks completeness regarding outcome or confirmation.

    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 add meaning beyond the schema; it merely restates that the parameter is an ID. Schema description coverage is 0%, and the description fails to compensate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (delete) and resource (application) with parameter (ID). It distinguishes from sibling tools like create_application and get_application.

    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, prerequisites, or side effects. The description is solely a statement of action.

    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 should fully disclose behavioral traits. It indicates a destructive action ('clear') but omits details like irreversibility, permission requirements, or scope of deletion (e.g., organization-wide or for a specific log).

    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 essential details. It is not overly verbose, but the brevity comes 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 no annotations, output schema, or parameter descriptions, the description should cover expectations about return values, scope, and side effects. It fails to do so, leaving the agent uncertain.

    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 does not mention the single parameter (organization_id) or its meaning. The description adds no value beyond the schema for parameters.

    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 'Clear the packet/frame log' uses a specific verb and resource, clearly distinguishing it from sibling tools that delete individual entities like applications or devices. It is unambiguous about the action.

    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., flushing a queue or deleting a device). No prerequisites or exclusions provided.

    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 should disclose behavioral traits. It states it queues a downlink (a write operation) and returns '{fCnt}', but does not clarify whether it appends or overwrites, whether the group must exist, or any side effects. Minimal behavioral info.

    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 plus a return note—which is concise but too sparse. It could be restructured to include key parameter details without adding much 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 complexity of 4 parameters, no output schema, and sibling tools, the description is incomplete. It fails to cover prerequisites, error conditions, parameter constraints, or return value context beyond '{fCnt}'.

    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?

    Input schema coverage is 0%, and the description adds no explanation for any of the four parameters. The meanings of 'data_base64', 'f_port', 'f_cnt', and 'group_id' are not elaborated. This is a critical gap.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('queue a downlink payload') and the target resource ('multicast group'). It distinguishes from the sibling tool 'enqueue_device_downlink' by specifying the group context, though it does not explicitly mention the alternative.

    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 'enqueue_device_downlink' or 'flush_multicast_downlink_queue'. The description lacks any 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, the description carries the full burden but only mentions the return format. It does not disclose read-only behavior, pagination details, rate limits, or authentication needs.

    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 for complex information. It is concise but at the expense 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 zero parameter descriptions, the description fails to cover pagination, filtering, or the meaning of organization_id. It is incomplete for a list tool with optional parameters.

    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 provides no information about the three parameters (limit, offset, organization_id). It adds no value beyond the schema types and defaults.

    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 lists LoRaWAN gateways and provides the return format, which distinguishes it from other list tools for different resources. However, it does not add extra differentiation beyond the resource name.

    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 (e.g., list applications, list devices). No context on prerequisites, filters, 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?

    With no annotations, the description carries full burden for behavioral traits. It only mentions return format, but lacks details on pagination, limits, or that it is a read-only operation. 'Recent' is vague.

    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 concise but lacks necessary detail. It is front-loaded with purpose but omits important context, balancing brevity with completeness poorly.

    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 optional parameter and no output schema, the description should at least explain the parameter and the return structure. The return format is shown but without field details, and 'recent' is undefined, making it incomplete for an AI 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 one parameter ('organization_id') with 0% schema description coverage. The description does not explain this parameter or how to use it, providing no additional 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?

    The description clearly states the action ('List') and the resource ('recent LoRaWAN packets (frame log)'). It distinguishes from sibling tools like 'delete_packets' and other list tools by specifying 'LoRaWAN packets'.

    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 does not mention prerequisites, context, or situations where another tool (e.g., 'delete_packets') would 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, the description must disclose behavioral traits. It only says 'Update', indicating mutation but fails to mention whether the update is a full replacement or partial, side effects, required permissions, idempotency, or how missing fields are handled. This is insufficient 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 sentence, which is concise. However, it sacrifices completeness for brevity, offering no additional context. While efficient, it does not earn its place due to lack of useful information beyond the tool's name.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the absence of annotations, output schema, and any parameter explanations, the description is severely incomplete. It does not provide enough context for an AI agent to correctly invoke the tool, understand return values, or handle errors. The tool's complexity (4 params, nested object) demands far more detail.

    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 with 0% coverage in the description. The description does not explain any parameter's meaning, usage, or constraints. For example, 'profile' is a nested object with additionalProperties, but no guidance on its structure or required fields. This leaves the agent completely in the dark about parameter semantics.

    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 'Update an existing device profile' clearly states the action (update) and the resource (device profile). It distinguishes from sibling tools like create_profile and delete_profile by specifying 'update', but does not differentiate from update_device or update_application beyond the resource name.

    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 create_profile, update_device, or other update tools. The description lacks any context about prerequisites, typical use cases, 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 provided, the description bears full responsibility for behavioral disclosure. It only explains two parameters (group_type, frequency) and omits critical details like side effects, idempotency, error behavior, or what happens on success (e.g., returns group ID).

    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, consisting of two short sentences and a parameter note line. Every word contributes, but the structure could be improved by grouping related information or listing 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's complexity (10 parameters, no output schema, no annotations), the description is severely incomplete. It fails to explain return values, constraints, or the meaning of most parameters, making it insufficient for reliable agent usage.

    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%, meaning most parameters are undocumented. The description adds meaning for only two parameters (group_type enum values, frequency unit) but leaves 8 parameters unexplained, including required ones like name, mc_addr, and keys.

    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 'Create a multicast group', providing a specific verb and resource. However, it does not explicitly differentiate from sibling tools like add_device_to_multicast_group, relying on the verb 'create' to imply distinction.

    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, such as when to create vs. add devices to an existing group. No usage context or prerequisites are mentioned.

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

  • Behavior2/5

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

    No annotations are provided, and the description does not disclose any behavioral traits such as side effects, permissions required, or whether the operation is idempotent. The description merely restates the action implied by the name.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is short and includes an example, which is good, but it is front-loaded with minimal text. It could be more concise while adding more substance, such as clarifying the optional nature of 'organization_id'.

    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 annotations and output schema, and the presence of a nested object parameter, the description is incomplete. It does not explain return values, error states, or the full scope of the tool's capabilities.

    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 description coverage, the description only adds meaning for the 'profile' parameter via an example, but completely ignores the 'name' and 'organization_id' parameters. The schema provides structure, but the description fails to clarify their roles or formats.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Create a device profile' and provides an example of the profile object, distinguishing it from sibling tools like 'update_profile' or 'delete_profile'. However, it could be more specific about what a device profile entails in the LoRaWAN 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 is provided on when to use this tool versus alternatives (e.g., 'update_profile'), nor are there any prerequisites or exclusions mentioned. The description lacks context for appropriate usage.

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

  • Behavior1/5

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

    No annotations are present, and the description only states 'Delete' with no details on side effects, irreversibility, permissions, or what happens to associated devices. The description carries the full burden but provides no 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.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words, but it may be too terse for a delete operation. It earns its place but could benefit from additional context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one param, no output schema), the description is incomplete. It does not address side effects, such as cascading deletions or impacts on associated devices, leaving the agent without necessary context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, and the description adds no meaning to the 'group_id' parameter. It does not explain the format, source, or constraints (e.g., must be a valid ID).

    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 'Delete' and the resource 'a multicast group by ID'. It is specific and distinguishes from sibling tools like 'remove_device_from_multicast_group' which handles device removals.

    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 prerequisites (e.g., group must exist) or constraints (e.g., cannot delete group with active devices).

    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 should disclose behavioral traits like read-only nature, pagination behavior, or side effects. It only says 'List devices' but doesn't mention that it is a read operation, supports pagination via limit/offset, or what happens if group_id is invalid.

    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 short (one sentence) but lacks structure; it is concise but not informative. It earns its place by being brief, but could be improved with front-loaded key details.

    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 three parameters and is a list operation, the description should cover pagination, return type, or output format. It does not, leaving the agent with insufficient context for correct invocation or interpretation of results.

    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 explain any of the three parameters (group_id, limit, offset) despite 0% schema description coverage. It fails to add meaning about required vs optional fields or their purpose.

    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 lists devices belonging to a multicast group, using a specific verb and resource. It distinguishes from sibling tools like list_multicast_groups (which lists groups) and add_device_to_multicast_group (which adds a device).

    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 list_devices or get_multicast_group. The description lacks context for appropriate use cases 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 carries full burden. It does not disclose pagination behavior, permissions, or what happens with empty results. The minimal description lacks transparency beyond the basic action.

    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?

    Very concise (two sentences) with purpose front-loaded. However, it is too minimal; missing parameter and usage details could be added without harming conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema exists, so description should explain return format (it does partially with {totalCount, result:[...]}) but lacks parameter explanations and usage context. For a list tool with pagination, this is incomplete.

    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%. The description mentions no parameters. Limit, offset, and organization_id are in the schema but with no explanations in the description, leaving their semantics entirely to the agent's inference.

    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 multicast groups' which is a specific verb-resource combination. It distinguishes from siblings like create_multicast_group or get_multicast_group. The return format hint also adds 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 compared to other list tools (e.g., list_devices) or any context for when it is appropriate. The description provides no usage direction.

    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?

    The description discloses the return format as '{totalCount, result:[...]}', which adds value beyond the schema. However, it does not mention side effects, authentication needs, or rate limits, leaving behavioral aspects unclear.

    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 front-loaded with the main purpose. However, it is under-specified, lacking necessary details for effective tool use, which reduces its 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 presence of three optional parameters, no output schema, and sibling list tools, the description is incomplete. It does not explain pagination, filtering, or how device profiles relate to other entities.

    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 (limit, offset, organization_id). The schema provides names and defaults, but no additional meaning is added.

    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 'List' and the resource 'device profiles', but it does not differentiate from sibling list tools such as list_applications or list_devices, and lacks specificity about what constitutes a device profile.

    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 get_profile for a single profile or create_profile for creation. No context or exclusions are given.

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

  • Behavior2/5

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

    With no annotations provided, the description carries full burden for behavioral disclosure. It only states 'Remove' without detailing consequences (e.g., idempotency, error handling, impact on group if device is last).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, which is concise but lacks necessary details. It is not padded with irrelevant information, but it is under-specified for the agent to use correctly.

    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 absence of output schema and annotations, and the minimal parameter documentation, the description is incomplete. For a simple removal operation, it still misses key aspects such as expected behavior when device is not in the group.

    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 only mentions 'dev_eui' but not 'group_id'. No details on format, constraints, or valid values are provided for either parameter.

    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 'Remove' and the resource 'device from a multicast group', and specifies the key identifier 'DevEUI'. It distinguishes from the sibling tool 'add_device_to_multicast_group' by indicating the opposite operation.

    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 'add_device_to_multicast_group' or other device management tools. There is no mention of prerequisites or conditions for removal.

    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 full burden. It states 'delete all pending downlink items' but omits critical behavioral details: whether the operation is irreversible, potential impacts on ongoing transmissions, required permissions, or side effects. A destructive mutation warrants more 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?

    Single sentence, front-loaded with verb and resource. No wasted words, but could be slightly more informative without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a destructive tool with one parameter and no output schema, the description is too sparse. It should explain the scope ('pending' meaning not yet transmitted), confirm irreversibility, and suggest how to verify the result. Lacks completeness for safe usage.

    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, and the tool description adds nothing about the group_id parameter – it does not specify format, source, or how to obtain it. The description fails to compensate for the missing schema documentation.

    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 (delete) and the resource (pending downlink items for a multicast group). It distinguishes itself from sibling tools like enqueue_multicast_downlink (add) and get_multicast_downlink_queue (retrieve), and from flush_device_downlink_queue (for 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 on when to use flush compared to alternatives like get_multicast_downlink_queue or enqueue. The agent is given no context for decision-making, such as when discarding pending items is 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 only says 'Update' which implies mutation, but with no annotations provided, it fails to disclose any behavioral traits such as side effects, permissions, or idempotency. The description carries the full burden and does not meet it.

    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 very concise, consisting of one sentence. However, it is arguably too concise, missing critical details. It earns its place but is not optimally structured.

    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 5 parameters, no output schema, and no annotations, the description is incomplete. It fails to explain parameter meanings, return values, or behavioral context, leaving significant gaps.

    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 add any meaning to the parameters. The agent must guess the purpose of fields like 'application_id', 'name', 'description', etc., from the schema alone.

    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 'Update' and the resource 'application', distinguishing it from create_application, delete_application, and other sibling tools like update_device. It is specific and unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as create_application or get_application. No prerequisites, exclusions, or context are 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?

    With no annotations, the description must disclose behavioral traits. It only states the action without mentioning idempotency, side effects (e.g., if device is already in group), or authentication requirements. This is insufficient 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?

    A single sentence is concise, but it lacks structure such as front-loading key constraints or separating purpose from context. The length is minimal, but valuable details are omitted.

    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 modifies state (adds device to group), the description is incomplete. It should clarify whether the group and device must pre-exist, what the response indicates, and potential error conditions. No output schema exists to compensate.

    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%, so the description must compensate. It identifies dev_eui as device identifier and implies group_id as the group, but offers no format details (e.g., DevEUI hex string, group_id UUID) or constraints. The schema provides only 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 (Add), the resource (device to a multicast group), and the identifier (DevEUI). It distinguishes from siblings like create_multicast_group and remove_device_from_multicast_group.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool vs alternatives, no prerequisites (e.g., group must exist), and no exclusions. Sibling tools like remove_device_from_multicast_group suggest a related removal action, but no contrast is given.

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

  • Behavior2/5

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

    No annotations are provided, so the description must bear the full burden. It does not disclose side effects (e.g., cascading deletes), reversibility, or required permissions. The minimal description adds no behavioral context beyond the action itself.

    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) with no waste, but it is underspecified. It could be improved with additional context without sacrificing brevity.

    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 delete operation with one parameter, the description is minimally adequate. However, missing behavioral details (e.g., whether the device must exist, consequences of deletion) reduce completeness.

    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 parameter dev_eui is only described as a string in the schema; the description adds that it identifies the device but does not provide format constraints or examples. With 0% schema description coverage, more detail is needed to compensate.

    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 'Delete a device by its DevEUI' clearly states the verb (delete) and the resource (device), distinguishing it from sibling delete tools like delete_application or delete_multicast_group.

    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 such as remove_device_from_multicast_group or update_device. No prerequisites or scenarios provided.

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

  • Behavior2/5

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

    No annotations are provided, so the description must convey behavioral traits. It only states 'delete' without disclosing side effects, reversibility, or any required permissions. This is insufficient for a destructive 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 very concise at one sentence, which is appropriate for a simple tool with one parameter. It is front-loaded with the action and resource, but could include more detail without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (1 parameter, no output schema, no annotations), the description is barely adequate. It does not mention error conditions, existence checks, or any impact on related entities, leaving gaps for the agent.

    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%, meaning the description should add meaning beyond the schema. The phrase 'by ID' offers minimal context for the single parameter 'profile_id' (string), leaving ambiguity about its format or constraints.

    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 'Delete' and the resource 'device profile' with the method 'by ID'. It effectively distinguishes from sibling tools like create_profile, get_profile, and update_profile, which have different verbs.

    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. For instance, there is no mention of prerequisites or conditions under which deletion should be avoided (e.g., if the profile is in 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 annotations are present, so the description must disclose behavioral traits. It only states 'get' without mentioning read-only nature, required permissions, error behavior, or any 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.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single succinct sentence with no wasted words. However, it could be slightly more informative without sacrificing conciseness.

    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, the description should explain what is returned (e.g., application object fields) and potential errors. It does not provide this context, leaving the agent underinformed.

    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 1 parameter with 0% description coverage. The description adds no meaning beyond 'by ID', failing to explain the format or origin of application_id. It does not compensate 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 'Get a single application by ID' clearly states the action (get) and the resource (application), and distinguishes it from sibling tools like list_applications or create_application.

    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 (e.g., list_applications), nor any prerequisites or context. The description lacks usage context entirely.

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

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It only states 'Get pending downlink items' implying a read operation but does not disclose behavior such as pagination, data format, or performance characteristics.

    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 short sentence that gets to the point. It is concise and front-loads the action, though it may be too terse for complete understanding.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity, the description lacks completeness. It does not explain what 'downlink items' are, the queue behavior, or the response format. With siblings like 'flush' and 'enqueue', more context is needed.

    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 does not explain the meaning of parameter 'dev_eui' or provide additional context beyond the schema. Baseline is low and the description does not compensate.

    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 'Get' and the resource 'pending downlink items queued for a device'. It uses a specific verb+resource combination and distinguishes from sibling tools like 'flush_device_downlink_queue' and 'enqueue_device_downlink'.

    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 adds no meaning for the required group_id parameter beyond its name. The agent gets no additional context on expected format or constraints.

    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 pending downlink items queued for a multicast group,' using a specific verb and resource. It distinguishes from siblings like get_device_downlink_queue and the enqueue/flush variants for multicast groups.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given three parameters with no descriptions, no output schema, and no annotations, the description is incomplete. It does not explain pagination via limit/offset or the optional organization_id filter. The return format is partially described but lacking full details.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 0%, meaning the input schema provides no descriptions for the three parameters: limit, offset, organization_id. The tool description adds absolutely no information about these parameters, leaving the agent to infer their meaning from names alone, which is insufficient.

    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 lists LoRaWAN applications on the gateway, using the specific verb 'list' and resource. It distinguishes from sibling tools like create_application, delete_application, and get_application, which have different purposes.

  • Behavior2/5

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

    With no annotations, the description must disclose behavioral traits. It mentions the return format (`Returns {id}``) and a constraint on service_profile_id, but lacks details on side effects, permissions, or idempotency. The description adds some value but is insufficient for a creation 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?

    The description is very concise with two sentences, front-loading the purpose and return format. No extraneous information. However, it sacrifices completeness for brevity, missing parameter explanations.

    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 with no schema descriptions and no output schema, the description should cover parameter details. It only addresses one parameter partially. Missing descriptions for name, description, and organization_id make it incomplete for agent decision-making.

    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%, so the description must compensate. It only adds meaning for service_profile_id (must be existing UUID). The other parameters (name, description, organization_id) remain undocumented, leaving the agent without guidance on their semantics.

    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 creates an application, distinguishing it from sibling tools like create_device or create_profile. The verb 'create' and resource 'application' are specific and unambiguous.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides a prerequisite for service_profile_id (must be existing UUID) but does not give explicit guidance on when to use this tool versus alternatives like update_application. Context is implied but not comprehensive.

    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 explains two parameters. It does not disclose behavioral traits such as whether this is a destructive operation, authentication needs, or if it appends to the queue.

    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 at two sentences, each serving a purpose. It is front-loaded with the primary action and efficiently explains key parameters.

    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 four parameters, no output schema, and no annotations, the description is incomplete. It omits the confirmed parameter explanation, does not describe return values, and lacks context on queue behavior.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 0% schema description coverage, the description adds meaning for two of four parameters: data_base64 and f_port are explained. However, the required dev_eui and the optional confirmed parameters are not described, leaving gaps.

    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 verb 'Queue' and the resource 'a downlink payload to a device', making the purpose specific. It distinguishes from sibling tools like 'enqueue_multicast_downlink' and 'flush_device_downlink_queue'.

    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 such as 'enqueue_multicast_downlink' or when to flush the queue. The description does not specify prerequisites or exclusion criteria.

    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?

    Since no annotations are provided, the description carries the full burden. It correctly implies a read-only operation but omits details about error handling, authentication, or rate limits. For a simple get, this is minimally adequate but lacks completeness.

    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 of 7 words. Every word serves a purpose with no fluff, making it highly concise and easy to parse.

    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 tool's simplicity (one parameter, no output schema), the description is adequate but not thorough. It does not describe the return format, potential errors, or what 'device profile' encompasses. A more complete description would mention the expected output structure.

    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 adds no meaning beyond the schema for the single parameter 'profile_id'. It merely restates 'by ID' without specifying format, constraints, or examples. With 0% schema description coverage, the description fails to compensate.

    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 'Get a single device profile by ID' clearly states the verb (Get), resource (device profile), and unique identifier method. It effectively distinguishes from sibling tools like list_profiles (which returns multiple) and CRUD operations.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, when not to use, or contrast with similar tools like list_profiles or get_device.

    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?

    The description implies a read-only operation, which is appropriate for a getter. However, without annotations, it lacks details on permissions, error conditions, or side effects. The basic nature keeps it adequate.

    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 extremely concise with one sentence. It could include more information, but it is efficient and front-loaded.

    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 simplicity (one parameter, no output schema), the description is minimally complete. It tells what the tool does but lacks return value or type details, which may be sufficient for a simple fetch.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description does not add semantics to the group_id parameter beyond 'by ID'. With 0% schema description coverage, the tool description should elaborate on what group_id represents.

    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 (Get) and the resource (single multicast group) with the retrieval method (by ID). It distinguishes from sibling tools like list_multicast_groups that return multiple groups.

    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 such as list_multicast_groups. No prerequisites or context provided.

    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 exist, so the description solely must disclose behavior. It states 'Get', implying a read-only operation, but fails to mention any side effects, permissions, or what the settings contain. This is insufficient for a tool with no other metadata.

    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 with no unnecessary words. It is succinct and front-loaded with the purpose.

    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 no annotations, the description should provide more context about the returned data or any behavioral nuances. It is too minimal to fully inform the agent.

    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?

    The input schema has no parameters, so the baseline is 4. The description adds meaning by specifying 'embedded network server settings', which clarifies the scope beyond the empty schema. This adds value, earning a 5.

    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 'Get' and the resource 'embedded network server settings'. It gives a specific purpose, though it could further differentiate from siblings like get_packet_forwarder_network_servers. The word 'embedded' adds context, making it distinct.

    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 guidance is provided. The description does not indicate when to use this tool over alternatives, nor does it mention any prerequisites or context. The agent must infer usage from the tool name alone.

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

  • Behavior2/5

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

    No annotations are provided, and the description does not disclose any behavioral traits such as whether the operation is read-only, requires authentication, or has side effects. The agent is left unaware of the tool's impact.

    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, short sentence that immediately conveys the purpose. No unnecessary words or information.

    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 simplicity (no parameters, no output schema), the description is nearly complete. However, it leaves vague what 'configured' means and does not clarify the context of use (e.g., after setting up a gateway). Minor gap.

    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, so the input schema is fully described. The description adds no parameter information, but given no parameters exist, it is appropriately concise. Baseline 4 applies for zero-parameter tools.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Get') combined with a clear resource ('configured packet-forwarder network servers'). It uniquely identifies the tool's function among siblings, which include get_network_server_settings and other CRUD operations.

    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. The description does not mention prerequisites, context, or when not to use it.

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

  • Behavior4/5

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

    Despite no annotations, the description reveals the internal fetch-then-update behavior to handle mandatory fields. This adds significant transparency about side effects (the tool does a read before write). However, it does not mention any destructive actions or permissions needed.

    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 two clear paragraphs. The first sentence front-loads the purpose. The second paragraph adds necessary implementation detail without extra fluff.

    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 8 parameters with no schema descriptions, no output schema, and no annotations, the description is incomplete. It does not explain return values, parameter details, or usage examples. The behavioral note is helpful but insufficient.

    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 description coverage and 8 parameters, the description provides no individual parameter meanings. It only generalizes that provided fields are merged. This fails to compensate 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 'Update a device' with a specific verb and resource. It explains the merge behavior, distinguishing it from create or delete tools. The sibling tools are for different resources (applications, profiles), so no confusion.

    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 explains how the tool works (merge) but does not explicitly state when to use it versus alternatives like create_device or other update tools. It implies usage for partial updates but lacks explicit 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?

    With no annotations, the description carries full burden. It discloses that the tool creates a device and lists required parameters, but omits side effects, permissions, or reversibility. Basic behavioral context is provided but not exhaustive.

    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: two sentences covering purpose and activation requirements with no extraneous information. It is front-loaded and every sentence adds 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 12 parameters, no output schema, and no annotations, the description is incomplete. It covers only activation-specific parameters, leaving many fields (e.g., profile_id, name, skip_fcnt_check) unexplained. More detail is needed for full contextual completeness.

    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 description must compensate. It explains the purpose of dev_eui, application_id, and activation keys (app_key, dev_addr, app_s_key, nwk_s_key), but does not describe other parameters like name, f_port, profile_id, description, skip_fcnt_check, or payload_codec_id. Partial coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Register a new device under an application,' specifying the action (register) and resource (device). It distinguishes from sibling tools like delete_device or list_devices, and provides necessary context about activation modes.

    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 tool (registering a new device) and distinguishes between OTAA and ABP activation, specifying which parameters are required for each. However, it lacks explicit guidance on when not to use or comparisons with 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, the description should provide behavioral context. It accurately indicates a destructive operation ('Delete all pending'), but does not disclose if it is reversible, requires specific permissions, or affects other aspects like device state.

    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, concise sentence with no superfluous information, making it easily digestible.

    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 simplicity (1 required param, no output schema), the description adequately conveys the core action. Could be slightly more complete by noting that only pending items are affected, but overall sufficient.

    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?

    Parameter 'dev_eui' has no schema description (0% coverage), and the description only vaguely implies its purpose by mentioning 'for a device'. It adds minimal meaning beyond the parameter name.

    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 'Delete' and the resource 'all pending downlink items for a device', distinguishing it from siblings like 'enqueue_device_downlink' and 'flush_multicast_downlink_queue'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies use for clearing a device's downlink queue, but lacks explicit guidance on when to use vs alternatives like 'get_device_downlink_queue' or 'enqueue_device_downlink'.

    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 the return format (devTotalCount, deviceResult array) and the optional scoping, which adds behavioral context. However, it does not mention rate limits, authentication, or data freshness. The return format is helpful but not exhaustive.

    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: one sentence and a code block showing return structure. No unnecessary words, and the format is easy to parse. Every element serves a purpose.

    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 lack of annotations and output schema, the description provides the return format and optional scoping, but lacks details on parameter behavior (e.g., pagination, search semantics). It is minimally adequate but has clear gaps for an agent to fully understand the tool's behavior without additional inference.

    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 description coverage and 5 parameters, the description only hints at the application_id parameter via 'optionally scoped to one application'. It does not explain limit, offset, search, or organization_id, leaving the agent to rely solely on parameter names and types. More semantic information is needed.

    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 ('List') and the resource ('devices'), and mentions optional scoping to one application, which distinguishes it from sibling tools like list_applications or list_gateways.

    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 context for when to use the tool (listing devices with optional application scoping) but does not explicitly exclude alternatives or state when not to use it. The context is clear enough for an agent to select appropriately.

    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. It explains that there is no direct per-DevEUI GET endpoint, so the tool searches the device list. This discloses the underlying behavior, though it does not cover error cases (e.g., device not found).

    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. The second sentence adds valuable context without unnecessary words. Every sentence 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?

    For a simple retrieval tool with one parameter and no output schema, the description adequately explains what it does and the underlying mechanism. It lacks details on return format and error handling, but covers the essential information 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.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The only parameter is dev_eui, and the description adds that it is the identifier. However, since the parameter name is self-explanatory and schema coverage is 0%, the description provides minimal additional meaning. It marginally clarifies the role of the parameter.

    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 'Get a single device by its DevEUI', which is a specific verb and resource. It effectively distinguishes from sibling tools like list_devices (which returns all) and other device operations.

    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 retrieving a specific device by DevEUI. It does not explicitly exclude other tools or provide when-not-to-use guidance, but the purpose is clear enough for the agent to select it appropriately.

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

  • Behavior4/5

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

    No annotations are provided, so the description carries the full burden. It discloses the return format explicitly, which is good. However, it does not mention permissions or side effects, but as a read-only list tool with no parameters, the transparency is reasonably high.

    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: one sentence plus a return format specification. Every part earns its place, and it is front-loaded with the purpose.

    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 parameters, no output schema, and a simple list operation, the description fully covers what an agent needs: purpose and return format. It is complete for the tool's 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?

    There are no parameters, and the schema coverage is 100%. The description adds value by specifying the return format, which compensates for the absence of parameters. Baseline for 0 params is 4.

    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 available payload codecs (short form)' with a specific verb and resource. The return format is provided. The tool is distinct from siblings, which focus on CRUD operations for applications, devices, groups, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies use for listing codecs but does not explicitly state when to use this tool versus alternatives or provide context for when not to use it. Given its simplicity, it is adequate but lacks explicit guidance.

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