Busy Bar MCP Server
Server Quality Checklist
Latest release: v0.1.0
- Disambiguation3/5
Most tools target distinct endpoints, but there is overlap between the comprehensive get_device_status and its individual sub-getters (e.g., get_device_info, get_firmware_info, get_system_status, get_power_status), which could lead to redundant calls. Similarly, get_transport and get_wifi_status both relate to network connectivity, and the three account getters (info/status/backend) are closely related, though descriptions help differentiate them.
Naming Consistency4/5The naming pattern is overwhelmingly consistent: almost every tool follows get_<resource>. The only deviations are list_storage_files (uses 'list' instead of 'get') and get_tzlist (a slightly non-standard noun form for a list), but these are minor and do not seriously disrupt the overall pattern.
Tool Count2/528 tools is above the threshold where a toolset starts to feel heavy; the calibration suggests 25+ tools is too many. While each tool corresponds to a distinct device endpoint, the sheer number of read-only getters makes the surface feel bloated and could overwhelm an agent, especially since many are minor status variations.
Completeness2/5The tool surface is entirely read-only—there are no set, update, create, or delete operations. This is a significant gap for a device management server, as users cannot change brightness, volume, timezone, device name, firmware update settings, or perform any configuration action. The description of get_tzlist even references set_timezone, implying such functionality should exist but does not.

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
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It discloses that the tool queries GET /api/update/autoupdate and returns an AutoupdateSettings object with specific fields, which is useful. However, it does not mention potential side effects, error behavior, or network dependencies, leaving moderate gaps for a read-only network call.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a summary, technical details, return fields, and use case. It is slightly verbose (e.g., mentioning 'UpdaterApi.get_autoupdate_settings()' is arguably extra), but each sentence adds value and it remains readable.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description adequately explains the return object fields (is_enabled, interval_start, interval_end) and provides a practical use case. It covers the essential information for a simple getter with no parameters, though it omits error conditions and edge cases.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, and schema coverage is 100% vacuously. The description does not need to explain parameters, and it appropriately focuses on return value structure and use case. Baseline for zero parameters is 4, and nothing lowers it.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool 'Retrieve automatic firmware update settings from the Busy Bar device,' which is a specific verb+resource. It distinguishes from siblings like get_firmware_update_status by explicitly targeting autoupdate settings, and the details about the API endpoint reinforce the specificity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a clear use case: 'Confirm when or whether firmware updates happen automatically, to avoid unexpected reboots during active usage or schedule maintenance around the update window.' It gives practical context for when to use the tool, though it does not explicitly discuss alternatives or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses that it calls StorageApi.list_storage_files(path), enumerates directory contents, and returns a StorageList with file/dir elements. However, it does not describe error behavior (e.g., invalid/nonexistent path), sorting order, or whether the listing is recursive, which are relevant for an agent to predict 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.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a clear opening statement, an 'Args' section, a 'Returns' section, and a 'Use case' section. It is slightly verbose (e.g., 'enumerate the directory contents' followed by the return element list), but every sentence contributes to understanding the tool's behavior and purpose. It remains concise for the amount of information provided.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's low complexity (one parameter, no output schema, no annotations), the description is quite complete. It covers what the tool does, the parameter semantics, the return structure, and a realistic use case. The only gap is the lack of error handling information, but that is not critical for a simple read-only list operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The single parameter 'path' is explained thoroughly: 'The directory path to list (e.g., "/", "/photos"). Defaults to "/".' This adds meaning beyond the schema, which only shows a string with a default. The examples clarify the expected format and the default behavior, making the parameter easy to use correctly.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'List' and the resource 'files and directories stored on the Busy Bar device at a given path.' It distinguishes itself from sibling getter tools by focusing on storage file enumeration, and includes specific details like the underlying StorageApi call. This leaves no ambiguity about what the tool does.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a clear use case: 'Browse device storage to find files before uploading, downloading, or managing media assets for display on the Busy Bar unit.' While it doesn't explicitly mention when not to use it or name alternative tools, the context is sufficient for an agent to select it for storage browsing tasks. Sibling tools are all get_* status/info commands, so this tool is clearly the only one for listing files.
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 behavioral burden. It discloses that this is a GET request and lists all return fields, but it does not explicitly state side effects (e.g., read-only) or error conditions. The endpoint and return structure provide some transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured: a one-line summary, implementation detail, bulleted return fields, and a use case. It is concise without being sparse, and every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple zero-parameter getter, the description covers the purpose, return object, and use case. It lacks explicit error handling details, but the provided information is sufficient for an agent to invoke the tool correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema has zero parameters, so the description cannot conflict with it. The baseline for 0-param tools is 4; the description focuses on the operation and return object, which is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with 'Retrieve linked account information from the Busy Bar device,' providing a specific verb and resource. It further details the exact API endpoint and method, distinguishing it from sibling tools like get_account_status and get_account_backend.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
A dedicated 'Use case' section states 'Verify an account is properly linked and inspect the associated email before performing account-specific operations,' giving clear context for when to call this tool. It does not explicitly mention alternatives, but the use case is sufficiently clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses that the tool sends a GET request to a specific endpoint, implying read-only behavior, and describes the returned UpdateStatus object. However, it does not explicitly state that there are no side effects, permission requirements, or error conditions, which would improve transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and well-structured, starting with a clear purpose statement, then explaining the endpoint and return object, and ending with a 'Use case' section. Every sentence adds value without unnecessary verbosity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Since there is no output schema, the description compensates by explaining the UpdateStatus object and its fields (install and check). It also provides a practical use case. It could add details on error handling or fields' meanings, but for a zero-parameter read tool, it is largely complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so there is nothing to document. The description appropriately focuses on the return value instead of parameter details, which aligns with the baseline 4 for zero-parameter tools.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Retrieve firmware update state from the Busy Bar device' with a specific verb and resource. It further clarifies the purpose by explaining the endpoint and the returned object, distinguishing it from sibling tools like get_firmware_info and get_update_changelog.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'Use case' section explicitly indicates when to use this tool: 'Verify which firmware is running and whether a new update has been detected but not yet installed — useful for maintenance and rollout planning.' It provides clear context but does not mention when not to use it or name alternatives, so it stops short of a 5.
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, the description carries the full burden of disclosure. It explicitly states that the tool 'queries /api/time/timezone' and returns a TimezoneInfo object with fields (name, offset, abbr), making the read-only nature clear. It does not discuss error conditions or permissions, but for a zero-parameter fetch this is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is efficiently structured: a one-sentence summary, the endpoint path, a formatted list of return fields with types, and a practical use case. Every sentence contributes value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple (zero params, no output schema), but the description fully specifies the return shape and types. It provides enough context for an agent to invoke the tool and interpret the result without additional information.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There are no parameters, and the schema properties object is empty (100% coverage by default). The baseline of 4 applies, and the description adds no parameter-specific details because none are needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a specific verb ('Retrieve') and resource ('current timezone configured on the Busy Bar device'), clearly stating the tool's function. It does not explicitly contrast with sibling tools like get_time or get_tzlist, but the phrase 'configured timezone' makes the intent distinct enough.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
A 'Use case' section provides clear context for when to call this tool: 'Checking which timezone the device is configured to so you can display times correctly or decide whether an update is needed.' However, it does not mention when not to use it or name alternative tools, so it stops short of full guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the transparency burden. It discloses the HTTP GET endpoint and the API method, and describes the return object and its changelog field. However, it doesn't address error behavior, missing versions, or authentication requirements, leaving some gaps for a network-dependent read operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is efficiently organized into Intro, Args, Returns, and Use case sections. Every sentence contributes necessary information—endpoint, parameter details, return shape, and usage context—with no redundancy or fluff.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (one parameter, no output schema), the description is quite complete: it states the API endpoint, parameter format, return type, and use case. It could add error-handling details, but for a basic read-only changelog fetch, the coverage is sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema only states that 'version' is a string, but the description enriches it by explaining it is a 'firmware version string' and provides an example ('1.0.0'). This adds meaningful context beyond the bare schema, effectively compensating for zero schema description coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a specific verb-resource pair: 'Retrieve the changelog for a specific firmware version from the Busy Bar device.' It clearly distinguishes this tool from the many sibling status-getters by focusing on the update changelog resource.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides a concrete use case: 'Review what changed in a specific firmware revision before deploying updates, or compare versions to understand new features and bug fixes.' This gives clear context for when to use the tool, though it doesn't explicitly mention alternatives or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It discloses the underlying HTTP endpoint (GET /api/ble/status), the API method (BLEApi.get_ble_status()), and the exact response fields with types and example values. This goes well beyond a simple 'get status' and reveals the read-only nature implicitly, though it does not mention error conditions or access requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is structured with an opening sentence, a technical detail sentence, a return field list, and a use case. Each section adds value, but it is slightly verbose compared to the two-sentence high benchmark. Still, it is well-organized and front-loaded with the primary purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple parameterless getter with no output schema, the description covers the essential aspects: what it does, how it does it (endpoint/method), what it returns (with field types and examples), and when to use it. It lacks explicit error/disconnected device behavior, but the provided information is sufficient for an agent to invoke and interpret results.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the description needs no parameter documentation. The schema coverage is 100% (trivially), and the description adds no param semantics required. Baseline for 0 params is 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function with a specific verb+resource: 'Retrieve BLE module status from the Busy Bar device.' It uniquely identifies BLE status among the sibling get_* tools, and the mention of returning status and address provides concrete scope.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'Use case' section provides clear context: verify BLE module is powered on and has a valid address before Bluetooth operations like smart home pairing or device discovery. This gives strong guidance, though it does not explicitly name alternatives or exclusions, which prevents a 5.
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, the description carries the full burden. It discloses that the tool queries a specific API endpoint and returns a StatusFirmware object with a detailed list of fields, which adds significant behavioral context. However, it does not explicitly state the operation is read-only, nor does it mention error handling or permission requirements. The GET verb and 'retrieve' imply non-destructive behavior, but the absence of explicit safety disclosure prevents a higher score.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a brief introduction, a detailed return field list, and a clear use case section. It is appropriately sized for the tool's complexity, though the field list is somewhat long. Each sentence contributes useful information, and the structure aids readability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a no-parameter tool with no output schema, the description is quite complete. It includes the API endpoint, the full return object fields with examples, and a use case. It lacks mention of potential errors, authentication requirements, or rate limits, but for a simple read-only status query, the provided information is sufficient for an agent to invoke the tool and interpret the result.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the baseline is 4. The description does not need to explain parameter semantics, and the schema already covers the empty parameter set completely. The description adds no parameter-related information, but none is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves firmware version details from the Busy Bar device, and identifies the specific endpoint (GET /api/status/firmware). It distinguishes itself from siblings like get_firmware_update_status by focusing on the currently installed firmware, not update status. The verb 'retrieve' and resource are 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 Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a clear use case: verify firmware revision before deploying updates or diagnosing firmware-related bugs. This gives context for when to use the tool, but it does not explicitly mention when not to use it or point to alternative tools for related tasks such as update status or changelog.
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, the description carries the full burden. It discloses the underlying API endpoint (/api/transport), the meaning of the returned information, and typical values ('usb' or 'wifi'). This is useful behavioral context beyond the schema, though it does not mention potential errors 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.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and front-loaded with the core purpose. It includes an API endpoint, typical return values, and a use case in a small amount of text. It could be shorter, but all sentences contribute meaningful information.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (no parameters, no output schema), the description is fairly complete. It explains the purpose, the API endpoint, possible return values, and a use case. It stops short of describing the exact output format or error scenarios, but is sufficient for a basic getter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, and the schema indicates no properties. The description accurately implies there are no inputs, so there is nothing to explain. The baseline score of 4 is appropriate for a parameterless tool.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves the current network transport type used by the Busy Bar device, with a specific verb and resource. It distinguishes from sibling tools by focusing on transport type, which is unique among the listed get_* tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a clear use case: 'Diagnose connectivity path issues; shows whether the device is reachable via USB network interface or a Wi-Fi connection.' This gives context for when to use the tool, though it does not explicitly mention alternatives 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?
No annotations are provided, so the description carries the burden. It discloses that this is a GET request, returns the latest scan results, and details the response structure. It does not mention potential edge cases like empty scan results or whether the scan is triggered, but the read-only nature is clearly implied by 'Retrieve' and 'GET'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is moderately sized and well-structured with clear sections for the return object and use case. It is a bit verbose but every sentence serves a purpose, and the structure improves readability.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no output schema, the description fully explains the return values (count and network list with fields) and provides a use case. It lacks mention of error handling or empty results, but for a simple no-parameter getter, the description is sufficiently complete for an agent to select and invoke it correctly.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the description does not need to add parameter details. The baseline for zero-parameter tools is 4, and the description appropriately avoids unnecessary parameter information.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool retrieves currently scanned Wi-Fi networks from the Busy Bar device, specifying the endpoint and method. It distinguishes itself from sibling tools like get_wifi_status by focusing on the list of available networks, not the current connection status.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a clear use case (browsing networks before switching access points or checking signal quality) but does not explicitly mention when not to use it or contrast with sibling tools. The use case is specific enough to guide an agent, but exclusions are missing.
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 burden of disclosing behavior. It explicitly mentions 'This tool queries GET /api/audio/volume' and 'Retrieve,' indicating a read-only operation. It also describes the return type (AudioVolumeInfo) and its single field, which is useful context. However, it does not discuss error cases or side effects, though for a simple getter these are minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with a clear purpose statement, a concise implementation note, return value details, and a practical use case. It is slightly verbose with the 'Returns an AudioVolumeInfo object containing: - volume (int)' list, but that information is useful given the lack of an output schema. Every section contributes to understanding the tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple tool with no parameters, no annotations, and no output schema, the description covers all necessary aspects: what it does, how it does it (GET endpoint), what it returns, and when to use it. It even mentions a real-world use case, which helps an agent decide to invoke it. No critical information is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the input schema is empty. The baseline for zero parameters is 4, and the description appropriately does not attempt to explain parameters that do not exist. It adds no parameter-specific information, but none is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Retrieve the audio volume setting from the Busy Bar device.' This uses a specific verb ('Retrieve') and resource ('audio volume setting'), and explicitly names the device. It distinguishes itself from sibling get_* tools by focusing on audio volume, which is unique among them.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'Use case' section provides a clear context: 'Check or audit volume settings before playing audio notifications or tones; useful for confirming device is configured at an audible level.' This tells an agent when to use the tool, but does not explicitly mention when not to use it or name alternatives. Since there are no sibling tools for audio volume, explicit exclusions are unnecessary.

Given no parameters, no output schema, and a simple read-only operation, the description is complete. It explains what the tool returns, why to use it, and how it differs from similar tools. It lacks error details, but that is not essential for this simple getter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the schema covers 100%. The description adds no parameter-specific info, but none is needed. The baseline for zero parameters is 4, and the description appropriately notes the return structure instead.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: to retrieve storage capacity information from the Busy Bar device. It uses a specific verb ('Retrieve') and resource ('storage capacity'), and distinguishes itself from sibling tools like list_storage_files by focusing on capacity rather than file listing.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a clear use case: checking available storage before uploading files/media and monitoring consumption over time. While it doesn't explicitly mention alternatives or exclusions, the use case gives sufficient context for when to use this tool.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses that the tool performs a GET request (implying read-only), and explicitly lists the return fields with types and descriptions. This gives a transparent picture of behavior, though it does not mention potential errors or permissions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured and front-loaded with a one-sentence summary, followed by technical context, a bulleted return-field list, and a practical use case. Every section adds value without unnecessary padding.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple, parameterless tool, the description is complete. It explains what the tool does, the endpoint it calls, the return structure (since no output schema exists), and a specific usage scenario. The context signals indicate low complexity, and the description fully covers all necessary information.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the input schema is empty. The baseline for 0 params is 4. The description correctly avoids adding unnecessary parameter info, and the schema coverage is 100% by virtue of having no properties.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The first sentence clearly states the verb ('Retrieve') and resource ('detailed system metrics from the Busy Bar device'). It distinguishes itself from sibling tools like get_storage_status or get_power_status by focusing on system-wide resource usage and health information.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides a concrete use case: monitoring available system resources before heavy operations to avoid exhausting the device. This gives clear context for when to use the tool, though it does not explicitly name alternatives or state when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavior itself. It states the endpoint (/api/time), the return object (TimestampInfo), the timestamp field, and the ISO 8601 format with timezone example. For a read-only getter, this is adequate transparency, though it doesn't explicitly mention being non-destructive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured: a one-sentence summary, then the endpoint and return format with an example, and a use-case paragraph. No redundant or unnecessary text; every sentence contributes to understanding the tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a zero-parameter, no-output-schema tool, the description provides complete context. It covers what the tool does, how it works (endpoint), exactly what it returns (TimestampInfo with timestamp field and format), and when to use it. This fully compensates for the lack of structured output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so the baseline is 4. The description appropriately omits parameter details because there are none, and the schema coverage is already 100% (mirroring the empty properties).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with a clear statement: 'Retrieve the current timestamp from the Busy Bar device's real-time clock.' This specifies the verb (retrieve), resource (timestamp/real-time clock), and distinguishes it from sibling tools like get_timezone. No ambiguity.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5Does the description explain when to use this tool, when not to, or what alternatives exist?
Provides a 'Use case' section explaining this is for querying the device's clock as an authoritative time source for scheduling, logging, or coordinating with BUSY timers. This gives clear context, but doesn't explicitly contrast with alternatives; however, no sibling tool retrieves the current time, so the context is sufficient.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
- Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of explaining behavior. It discloses that it performs a GET request to a specific endpoint, returns an AccountStatus object with possible status values, and suggests a follow-up action based on the result. It does not explicitly state read-only or authentication details, but those are implied by the retrieve action and the simple nature of the tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured: a clear first sentence, a technical detail, a return specification, and a practical use case. Every sentence adds value, and the use case is concise but illuminating. No filler or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the absence of an output schema, the description adequately explains the return format, including the status field and all possible values. It also provides a real-world scenario, making the tool's purpose and expected inputs/outputs fully clear for a parameterless operation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has zero parameters, so no parameter explanation is needed. Per the rubric, a baseline of 4 applies for parameterless tools. The description focuses instead on the return value and usage context, which is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('Retrieve') and identifies a precise resource ('MQTT connection status for the linked account from the Busy Bar device'), making its purpose unmistakable. This distinguishes it clearly from sibling tools like get_transport or get_account_info, which cover different domains.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly states a use case: 'Check MQTT connectivity before pushing data that requires cloud sync; if the account is not connected, queue operations locally until reconnection.' This gives the agent concrete guidance on when to call the tool, and implies when it may be unnecessary, with no comparable alternative among siblings.
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 exist, so the description carries the behavioral burden. It clearly indicates a read-only query operation ('queries', 'returns') and documents the exact endpoint. It also details the return object structure, which provides strong transparency, though it could explicitly state it has no side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-organized: a one-line summary, endpoint reference, structured return type with field explanations, and a use-case section. Every sentence adds value, and it is appropriately sized for a simple tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description is complete for this tool's complexity. It specifies the endpoint, return object fields, and practical use cases. Even without an output schema, it fully explains the returned timezone list, making the tool self-contained.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With zero parameters, the parameter baseline is 4. The description correctly indicates the tool takes no parameters and focuses on what it returns, so no additional parameter documentation is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states a specific action ('Retrieve the full list of supported timezones') targeting a specific resource (the Busy Bar device's /api/time/tzlist). It distinguishes itself from sibling get_timezone by focusing on the list of supported timezones rather than the current timezone.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5Does the description explain when to use this tool, when not to, or what alternatives exist?
The 'Use case' section explicitly explains when to use this tool: browsing timezones before setting one, building a UI dropdown, or confirming support. This provides clear guidance on when to use it versus alternatives like get_timezone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
