LibreLink Up B2B (CGM clínica)

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

Annotations indicate idempotentHint true, destructiveHint false. Description adds context: token is JWT, calling without args returns link, with token performs session login. No contradictions. Adds value beyond annotations.

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

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

Description is somewhat lengthy but efficiently conveys necessary steps and options. Front-loaded with purpose. Slight redundancy but overall well-structured.

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

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

No output schema; description does not specify return format for either case (link or token acceptance). Agents may need to guess response structure. Incomplete for a tool with no output schema.

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

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

Schema has one optional string parameter 'token' with 0% coverage. Description fully explains its meaning: when provided, it's a JWT for session login; when omitted, returns login link. Adds complete semantics.

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

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

The description clearly states the tool is for authentication: logging in, obtaining an access token, and using it. It differentiates from sibling tools which are all unrelated to auth.

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

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

Explicitly explains when to use (for IDE agents), provides step-by-step instructions (login in browser, copy token, add to config or paste), and distinguishes between permanent and session-only login.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the agent knows it's safe and non-mutating. The description adds value by detailing the output in different states (authenticated:true vs connect_urls), which is beyond what annotations provide.

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

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

The description is two sentences long, with no wasted words. It is front-loaded with the core purpose and then elaborates on states. Every sentence earns its place.

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

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

Given the tool has no parameters and no output schema, the description covers the main return states well. It could be slightly more complete by mentioning possible error states or additional fields, but overall it's sufficient for the agent to understand the output.

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

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

There are zero parameters, and the schema coverage is 100%. The description adds no parameter information because none is needed. It correctly focuses on the return values.

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

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

The description clearly states the tool returns connection status and URLs, and explains the different states (all providers connected vs missing credentials). It uses specific verbs and outcomes, distinguishing itself from the sibling 'authenticate' tool.

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

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

The description implicitly tells when to use this tool (to check connection status) versus 'authenticate' (which presumably initiates auth). It could be more explicit about when not to use it, but the context is clear from the sibling list.

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

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

Annotations already indicate readOnlyHint=true, idempotentHint=true, destructiveHint=false. Description adds valuable behavioral context: 'Read-only CGM data — clinic/follower account' clarifies authentication scope, and 'not for medical decisions without clinician review' sets expectations. Also reveals bulk support via patient_ids. No contradiction with annotations.

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

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

Extremely concise: two sentences plus a one-line note. First sentence states core purpose, second provides usage guidance, and third adds bulk support. No filler, perfectly front-loaded.

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

With no output schema, the description covers return data (value, trend, flags), usage constraints, and batch capability. It's sufficient for a simple read operation. Could mention potential errors or rate limits, but given annotations (idempotent, read-only), it's nearly complete.

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

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

Schema coverage is 0%, so description must carry parameter semantics. It explains the second parameter: 'Bulk support: accepts patient_ids for batched execution.' It does not explain that patient_id returns a single reading or that patient_ids returns multiple, but it provides enough functional context. A bit more detail on batch output would raise this to 5.

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

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

The description clearly states 'Latest glucose reading for a patient (value, trend, flags)', specifying the verb (get current), resource (glucose reading), and key data elements. It distinguishes from sibling tool librelink_business_get_glucose_graph by mentioning 'For history use...', so purpose is precise and differentiated.

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

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

Explicitly instructs when to use an alternative: 'For history use librelink_business_get_glucose_graph.' Also provides context on appropriate use cases: 'Read-only CGM data — clinic/follower account; not for medical decisions without clinician review.' This guides agent on when to invoke and when to avoid.

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

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

Beyond annotations (readOnlyHint, idempotentHint, destructiveHint), the description adds behavioral context: the data is for clinic/follower accounts, not for medical decisions, and includes a 12-hour resolution. This provides helpful additional constraints.

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

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

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

With 0% schema coverage, the description adds some meaning by mentioning 'patient_ids for batched execution' and implying the singular patient_id. However, it lacks explicit details about parameter types or formats.

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

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

The description clearly states it retrieves a '~12h high-resolution glucose graph (graphData)' for CGM data, distinguishing it from sibling tools like get_current_glucose or get_glucose_logbook. The verb 'get' and resource 'glucose graph' are specific.

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

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

The description implies use for high-resolution 12-hour graph data and mentions 'bulk support' with patient_ids, but does not explicitly specify when to use this tool versus alternatives like get_last_hours. No exclusions are provided.

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

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

Annotations already declare readOnlyHint, destructiveHint, idempotentHint. The description adds value by specifying data scope (~14 days), type (manual-scan, not continuous), and usage constraints (clinic/follower account, not for medical decisions). This behavioral context goes beyond the annotations.

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

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

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

The description covers purpose, usage, and behavioral aspects, but lacks details about return format, data fields, or pagination. Given the absence of an output schema and the tool's simplicity, it is adequate but not fully comprehensive.

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

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 mentions 'accepts patient_ids for batched execution' for the optional array parameter, clarifying its batch use. However, it does not describe the required patient_id parameter beyond its existence, leaving some ambiguity about its format or role.

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

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

The description clearly states it is a 'Manual-scan logbook (~14 days)' and explicitly distinguishes it from the sibling tool for continuous graph by naming 'librelink_business_get_glucose_graph'. The verb 'get' is implied by the tool name, and the resource is clearly defined.

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

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

Provides explicit when to use this tool ('Manual-scan logbook') vs the alternative ('For continuous graph use librelink_business_get_glucose_graph'). Also cautions that data is for clinic/follower account and not for medical decisions without clinician review, giving clear usage boundaries.

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

The description explicitly states the tool returns 'installed MCPs, their connection status, and how many catalog tools each exposes.' This is a specific verb+resource combination that clearly distinguishes it from sibling tools like 'authenticate' or 'connect'.

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

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

The description implies usage for checking toolkit state but does not provide explicit guidance on when to use this tool versus alternatives. No exclusions or when-not scenarios are mentioned.

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