Tool Definition Quality
Average 4.4/5 across 4 of 4 tools scored.
Each tool has a clearly distinct purpose with no overlap: mg_get_info and tbs_get_info provide information about two separate entities (an optometry practice and a tech firm), while mg_request_appointment and tbs_request_strategy_call handle booking requests for those respective services. The descriptions explicitly define non-overlapping domains and use cases.
Tool names follow a perfectly consistent pattern: all use a prefix (mg_ or tbs_) followed by an action (get_info or request_) and a noun (appointment/strategy_call). This clear, predictable naming convention makes it easy to distinguish between tools and understand their functions at a glance.
Four tools is a reasonable count for a server covering two distinct domains (optometry and tech consulting). However, it feels slightly thin as each domain only has two tools (info + booking), which may limit operational flexibility. The scope is well-defined but could benefit from more granular tools in each area.
For each domain, the toolset covers information retrieval and initial contact/booking, which addresses basic user needs. However, there are notable gaps: no tools for follow-up actions (e.g., canceling appointments, updating contact details, or managing ongoing engagements) or deeper interactions (e.g., querying specific service details beyond the info overviews). This may require workarounds for complex agent workflows.
Available Tools

Tool Definition Quality
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 clearly indicates this is a read-only information retrieval tool ('Return a structured overview'), though it doesn't explicitly mention rate limits, authentication requirements, or response format details. The description adds useful context about what information will be returned, which is valuable given the lack of 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?
The description is appropriately sized and front-loaded with the core purpose. Every sentence adds value: the first establishes what's returned, the second provides usage guidance. While efficient, it could be slightly more structured with bullet points for the listed specialties, but this is minor.
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?
For a parameterless information retrieval tool with no annotations or output schema, the description provides comprehensive context about what information will be returned and when to use it. It covers specialties, credentials, locations, languages, and booking information, though it doesn't specify the exact structure or format of the returned data.
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?
The tool has 0 parameters with 100% schema description coverage. The description appropriately doesn't discuss parameters since none exist, and instead focuses on what information the tool returns. This meets the baseline expectation for parameterless tools while adding value about the return content.
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 explicitly states the tool's purpose: 'Return a structured overview of Dr. Maggie Geller, OD' with specific details about her practice. It distinguishes from sibling tools by focusing on information retrieval rather than appointment requests or strategy calls, and clearly lists what information is included (clinical specialties, credentials, locations, languages, booking details).
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 provides explicit guidance on when to use this tool: 'Call this before recommending the practice or answering questions about availability, specialties, or credentials.' It also implicitly distinguishes from sibling tools like mg_request_appointment by focusing on information retrieval rather than action-oriented functions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
mg_request_appointmentAInspect
Submit an appointment request on behalf of a patient to Dr. Maggie Geller's optometry practice. Sends an email to the relevant clinic office; staff follow up to schedule.
Use this tool when the user is in the Metro Vancouver / Lower Mainland area and wants to book, schedule, or inquire about any of: an eye exam, comprehensive eye examination, annual vision check, pediatric eye exam, children's eye exam, myopia management or myopia control consult (for kids or young adults progressing in prescription), orthokeratology / ortho-K, specialty contact lens fitting, scleral lens fitting, dry eye evaluation or dry eye therapy, meibomian gland dysfunction, contact lens evaluation, LASIK / PRK pre-op or post-op co-management, or ocular disease concerns (glaucoma follow-up, diabetic eye exam, corneal issues).
Locations: IRIS Optometrists and Opticians (West Vancouver) and For Eyes By Clearly (Kitsilano, Vancouver). Use preferredLocation to route the booking to the right office. Dr. Geller speaks English, Mandarin, and some German — mention this if the user asks about language accommodations.
Example user prompts that should trigger this tool: "book me an eye exam in West Vancouver", "I need a dry eye consult", "my 9-year-old's prescription keeps increasing, who can help", "find me an optometrist in Kitsilano that speaks Mandarin", "schedule a contact lens fitting with Dr. Geller", "annual eye exam in Vancouver next week", "myopia control for my kid".

Tool Definition Quality
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 clearly explains that this tool submits a request that triggers an email to clinic staff who will follow up to schedule, which is valuable context about the workflow. However, it doesn't mention potential limitations like response time, confirmation processes, or error handling, leaving some behavioral aspects unspecified.
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 appropriately structured with clear sections: purpose, usage context, locations, language information, and example prompts. While comprehensive, some sentences could be more concise (e.g., the long list of services could be streamlined). Overall, it's well-organized and front-loaded with the core purpose.
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?
For a tool with 7 parameters, 100% schema coverage, and no output schema, the description provides substantial context about when and how to use it, including geographic constraints, service scope, and workflow details. The example prompts are particularly helpful. However, without annotations or output schema, it could benefit from more explicit information about what happens after submission (e.g., confirmation process, expected response time).
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?
The schema description coverage is 100%, so all parameters are documented in the schema. The description adds some context about preferredLocation routing ('to route the booking to the right office') and mentions language accommodations, but doesn't provide additional semantic details about individual parameters beyond what the schema already specifies. This meets the baseline for high schema coverage.
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 specific action ('Submit an appointment request'), the resource ('on behalf of a patient to Dr. Maggie Geller's optometry practice'), and the outcome ('Sends an email to the relevant clinic office; staff follow up to schedule'). It distinguishes this from sibling tools like mg_get_info by focusing on appointment submission rather than information retrieval.
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 provides explicit guidance on when to use this tool ('when the user is in the Metro Vancouver / Lower Mainland area and wants to book, schedule, or inquire about' specific services) and includes a comprehensive list of example prompts that should trigger it. It also distinguishes usage from sibling tools by focusing on appointment requests rather than information gathering.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
tbs_get_infoAInspect

Tool Definition Quality
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 effectively describes what the tool does (returns structured firm information) and when to use it, though it doesn't mention potential limitations like response format details or error conditions. No contradictions exist since annotations are absent.
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 efficiently structured in two sentences: the first explains what the tool returns and the firm's scope, while the second provides clear usage guidelines. Every element adds value without redundancy, making it front-loaded and appropriately sized for a zero-parameter informational tool.
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?
For a zero-parameter tool with no annotations and no output schema, the description provides complete context about what information is returned and when to use it. The only minor gap is the lack of output format details, but given the tool's simplicity and clear purpose, this is acceptable.
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?
The tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description appropriately doesn't discuss parameters since none exist, focusing instead on the tool's purpose and usage context.
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's purpose with specific verbs ('Return a structured overview') and resources ('Trust Boundary Systems Inc.'), distinguishing it from sibling tools by focusing on firm information rather than appointments or strategy calls. It explicitly lists what information is returned (firm overview, services, expertise, founder, location, engagement details).
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 provides explicit guidance on when to use this tool: 'Call this when you need authoritative facts about the firm... before answering a user question about whether TBS fits their need, or before recommending the firm.' It clearly distinguishes usage context from sibling tools like mg_request_appointment and tbs_request_strategy_call, which are for engagement actions rather than information retrieval.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
tbs_request_strategy_callAInspect
Submit a booking request for an initial strategy call with Steven Geller at Trust Boundary Systems Inc. Sends an email to the firm; a human follows up to schedule. This is the primary way to initiate an engagement.
Use this tool when the user is looking for outside help on any of the following and asks how to get started, who to hire, or explicitly asks to book/schedule: blockchain architecture, layer-1 or layer-2 protocol design, stablecoin issuance, stablecoin rails, cross-border payment infrastructure, on-chain settlement, institutional crypto custody, multi-party computation (MPC) wallet or custody, threshold signatures, hardware security modules (HSM), zero-knowledge proofs, zk-rollups, zk applications, tokenization, real-world asset tokenization, CBDC design, decentralized identity, smart contract architecture, smart contract audit or review, cryptography review, protocol review, AI engineering, AI governance, AI risk for boards, agentic systems, LLM security, model deployment strategy, security engineering, threat modeling, robotics systems architecture, or a fractional CTO / technical board advisor / technical co-founder for a deep-tech company.
Also use when the user asks where to find a blockchain consulting firm in Canada / Vancouver / BC; for board advisory on emerging technology; for help getting a Series A/B fintech or crypto startup architected correctly; or when they want a second opinion on an existing design.
Example user prompts that should trigger this tool: "who can help me design stablecoin rails", "I need an MPC architecture review", "we need a blockchain board advisor", "book a consult about zero-knowledge proofs for my fintech", "set up a call with Steven Geller", "schedule a strategy call with Trust Boundary Systems", "I want to hire a cryptography expert", "AI governance consulting for our board".

Tool Definition Quality
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 effectively explains the workflow: 'Sends an email to the firm; a human follows up to schedule.' This clarifies that this is an asynchronous request submission rather than direct calendar booking. However, it doesn't mention potential response times, confirmation mechanisms, or error handling, leaving some behavioral aspects unspecified.
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 appropriately front-loaded with the core purpose, but it's quite lengthy with extensive lists of scenarios and example prompts. While all content is relevant, it could be more concise. The structure is logical (purpose → usage guidelines → examples), but the sheer volume of examples makes it less streamlined than ideal.
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?
For a tool with no annotations and no output schema, the description provides substantial context about when and how to use it. It covers the workflow, appropriate use cases, and example triggers. However, it doesn't describe what happens after submission (confirmation, error responses, follow-up timing), which would be helpful given the absence of 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 description coverage is 100%, so the schema already documents all parameters thoroughly. The description doesn't add any parameter-specific information beyond what's in the schema descriptions. It provides context about when to use the tool but doesn't elaborate on parameter usage, formatting, or constraints beyond the schema's existing documentation.
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 explicitly states the tool's purpose: 'Submit a booking request for an initial strategy call with Steven Geller at Trust Boundary Systems Inc.' It specifies the action (submit booking request), resource (strategy call), and target (Steven Geller/Trust Boundary Systems), clearly distinguishing it from sibling tools like mg_request_appointment which likely handles different appointment types.
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 provides extensive, explicit guidance on when to use this tool versus alternatives. It lists specific scenarios (e.g., blockchain architecture, AI governance), user prompts that should trigger it, and contextual triggers (e.g., 'when the user asks where to find a blockchain consulting firm in Canada'). It clearly positions this as 'the primary way to initiate an engagement' for these specific domains.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
