1Stay Hotel Booking

TDQS

A4.4/5.0

Scored across 8 tools

Disambiguation4/5

Most tools target clearly distinct actions: search, book, cancel, lookup, and get. The only potential confusion is lookup_booking versus get_booking, since both can involve a confirmation number, but detailed descriptions clarify that one returns a summary/token and the other returns full booking details.

Naming Consistency5/5

All tool names follow a consistent verb_noun lowercase snake_case pattern: book_hotel, cancel_booking, get_booking, get_hotel_details, lookup_booking, resend_confirmation, search_hotels, search_tools. The naming is predictable and makes the tool set easy to navigate.

Tool Count5/5

Eight tools is well-scoped for a hotel booking server. Each tool covers a necessary part of the booking lifecycle without redundancy or unnecessary expansion, and the count is comfortably within the ideal 3-15 range.

Completeness4/5

The booking lifecycle is well covered: search, details, book, lookup, get, cancel, and resend confirmation. The only notable gap is the lack of a modify/update booking operation, but this can be worked around by cancelling and rebooking, and the server explicitly scopes its first release to single-room bookings.

Available Tools

8 tools
book_hotelBook HotelA
Idempotent
Inspect

Book exactly one hotel room. The first 1Stay release does not support multi-room searches or reservations. Returns a secure checkout URL. This tool accepts no guest identity or payment fields. Name, email, phone, and payment details are collected on the secure checkout page.

Guest pays the hotel directly. Their credit card statement shows the hotel name, not 1Stay. Hotel's own confirmation number. Loyalty points apply automatically. The displayed total includes taxes and any applicable, itemized 1Stay Booking Fee.

Requires a rate_code from get_hotel_details, valid approximately 15 minutes. Expired codes are rejected.

A4.7/5.0
Behavior5/5

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

Beyond the annotations, the description reveals important behavioral details: no guest identity or payment fields are accepted, payment is collected on a secure checkout page, the guest pays the hotel directly, loyalty points apply automatically, and the displayed total includes taxes and fees. This is substantial additional context.

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 front-loaded with the core purpose and return value, then efficiently covers constraints, payment behavior, and rate-code validity. Every sentence adds useful information without redundancy.

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?

The description covers the booking flow, payment responsibility, checkout URL, fee/tax behavior, and rate-code expiration. An output schema exists, so detailed return fields are not needed here. This is complete enough for an agent to understand how and when to call the tool.

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?

Schema description coverage is 100%, so the baseline is 3. The description adds meaningful value by explaining the provenance and expiry of rate_code, and by clarifying that no guest identity or payment parameters are accepted. This goes beyond the schema, justifying a 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 states a specific verb and resource: 'Book exactly one hotel room.' It also clarifies the operation's scope and what it returns ('Returns a secure checkout URL'), distinguishing the tool from booking-related siblings like cancel_booking, lookup_booking, and get_booking.

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 clearly establishes the booking context and prerequisites, especially that a rate_code must come from get_hotel_details and expires in about 15 minutes. It notes the current release does not support multi-room bookings, but it does not explicitly enumerate when to prefer one sibling over another. Nevertheless, the usage context is clear.

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

cancel_bookingCancel BookingA
Idempotent
Inspect

Prepare a hotel cancellation for completion on a secure 1Stay page. Verifies the guest's first name, last name, and hotel confirmation number, then returns the hotel policy classification and any cancellation deadline recorded with the reservation, plus a short-lived cancellation_url. 1Stay does not estimate a refund, credit, penalty, or hotel charge. Calling this tool never cancels the reservation. The guest must review the terms and select Cancel reservation on the secure page. Do not say the reservation was cancelled unless a later verified booking-status lookup reports status cancelled.

ParametersJSON Schema

TDQS

A4.4/5.0
Behavior5/5

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

Beyond annotations, the description discloses critical behaviors: input verification, no refund/penalty estimates, short-lived cancellation URL, and the fact that the action is not a cancellation but a preparation step. It also mandates the guest's manual confirmation step and cautions against asserting cancellation prematurely. These details go well beyond the sparse annotation hints and align with them—no contradiction.

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 about 100 words and contains no filler; every sentence earns its place, including the refund-policy disclaimer and the cancellation-status caveat. It front-loads the core purpose before caveats, but it is slightly longer than strictly necessary. A concise tool name and title could allow for a tighter statement, yet the detail is justified by the multi-step nature.

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

Completeness5/5

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

Given that an output schema exists, the description need not explain return values, but it still summarizes the key outputs (policy classification, deadline, cancellation_url) as context. It covers prerequisites, the external completion flow, and the follow-up verification requirement, leaving no major operational gap for an agent to misuse the tool.

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 input schema fully documents all three parameters with 100% coverage, so the baseline is 3. The description adds a small nuance by saying it 'verifies' these fields, implying they must match the reservation, but it provides no additional format, source, or validation semantics. It neither detects nor corrects parameter ambiguity, so it stays at the baseline.

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 opens with a specific verb and resource: 'Prepare a hotel cancellation for completion on a secure 1Stay page.' It then clarifies it verifies guest inputs and returns policy classification, deadline, and a cancellation URL. This sharply distinguishes it from sibling lookup tools like get_booking and lookup_booking, and the explicit 'Calling this tool never cancels the reservation' removes any ambiguity.

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

Usage Guidelines4/5

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

The description conveys clear context: use this tool to start a cancellation flow that the guest completes externally. It also warns not to claim cancellation until a later verified status lookup confirms it, implicitly steering the agent to a status tool afterward. However, it never names sibling alternatives or states when not to use this tool, so it falls short of an explicit when/when-not comparison.

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

get_bookingGet BookingA
Read-only
Inspect

Look up a reservation exclusively by the hotel confirmation number shown in the guest's confirmation email. Internal Stayker booking IDs are never accepted or disclosed by MCP. Returns full booking details including hotel, dates, guest info, rate, and status.

Anonymous access requires a verification_token issued by lookup_booking and scoped to a single booking. Without a valid token, no booking data is returned. Developers authenticated with their own API key do not need a token; their access is scoped to their own bookings.

ParametersJSON Schema

A4.9/5.0
Behavior5/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description adds rich behavioral context beyond that: the exclusive use of hotel confirmation numbers, the refusal to disclose internal IDs, the requirement for a verification token for anonymous access, and the guarantee that no data is returned without a valid token. 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.

Conciseness5/5

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

The description is well structured and front-loaded: the core purpose is stated in the first sentence, followed by the key constraint and the return summary, then the auth context in a compact second paragraph. Every sentence earns its place without redundancy or filler.

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?

The description covers what the tool returns, how it is uniquely identified, the authentication model, and the scope restrictions. Since an output schema exists, the return-value details do not need to be spelled out. The description is complete enough for an agent to select and invoke this tool correctly.

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 input schema already describes both parameters fully (100% coverage), so the baseline is 3. The description adds meaning by explaining that the verification_token must be booking-scoped and issued by lookup_booking, and clarifies that developer API-key-authenticated access bypasses the token requirement. This pushes it to a 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 states a specific verb ('Look up a reservation') and a specific resource ('by the hotel confirmation number'), and explicitly notes that internal Stayker booking IDs are never accepted. This distinguishes the tool's purpose from alternatives like lookup_booking and gives an agent immediate clarity on what it can and cannot do.

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

Usage Guidelines5/5

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

The description gives explicit when-to-use guidance: use this tool with the guest's hotel confirmation number. It also gives a when-not-to-use: internal booking IDs are never accepted. It further explains the prerequisite flow for anonymous access via lookup_booking and scopes developer access to their own bookings, so the agent knows exactly how to invoke it correctly.

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

get_hotel_detailsHotel DetailsA
Read-only
Inspect

Get rates and room details for exactly one room at a specific hotel. Returns room types, live rates, amenities, cancellation policies, and rate_codes required by book_hotel.

Guest pays the hotel directly. Displayed totals include taxes and any applicable, itemized 1Stay Booking Fee. Loyalty points eligible.

Room type notes: "Run of house" means the hotel assigns the room at check-in. "Suite" at select-service brands usually means a larger room with a sofa, not a separate bedroom.

ParametersJSON Schema
NameRequiredDescriptionDefault
roomsNoNumber of rooms. 1Stay currently supports exactly one room per search and reservation; omit this field or set it to 1.
guestsNoNumber of guests (default 2)
check_inYesCheck-in date in YYYY-MM-DD format (e.g. 2026-05-06)
hotel_idYesHotel ID from search results
check_outYesCheck-out date in YYYY-MM-DD format (e.g. 2026-05-07)
accessibleNoWhen true, returns accessible (ADA) room types instead of standard ones. Default false because hotels list many near-identical accessible variants. The response always reports accessible_rooms_available.

A4.1/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds valuable context beyond that: the guest-pays-hotel-directly payment model, that totals include taxes and an itemized booking fee, loyalty-point eligibility, and interpretive notes on 'run of house' and 'suite' room types — all useful for an agent presenting or acting on the data.

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?

Three short paragraphs, front-loaded with the core purpose and then adding high-value context: payment/fee disclosure and room-type interpretation. Each sentence earns its place; the room-type notes are domain knowledge that prevents misinterpretation of results rather than filler.

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 read-only lookup with full schema coverage, an output schema present, and safety covered by annotations, the description covers the remaining gaps: workflow position (feeds book_hotel), pricing transparency, and result interpretation. Nothing an agent needs to call it correctly is missing.

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 description coverage is 100%, so every parameter is already documented in the schema, including the accessible flag's behavior and the rooms field's one-room constraint. The description reinforces the 'exactly one room' limitation and notes that rate_codes feed book_hotel, but it does not need to add more — the schema carries the load, making baseline 3 appropriate.

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?

States a specific verb and resource — 'Get rates and room details for exactly one room at a specific hotel' — with an explicit scope constraint that distinguishes it from search_hotels. The closing link to book_hotel ('rate_codes required by book_hotel') positions it in the booking workflow, so an agent can tell exactly what this tool is for and what it is not.

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 gives clear context on when this fits: it returns rate_codes needed by book_hotel, and the 'exactly one room' constraint tells the agent it is a single-room lookup rather than a multi-room search. It stops short of explicitly naming alternatives or exclusion cases (e.g., 'use search_hotels to find hotels first'), so it is clear but not fully directive.

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

lookup_bookingLookup BookingA
Read-only
Inspect

Look up a reservation by verifying the guest's identity. Returns the confirmation number and booking summary in conversation.

Requires the guest's full name plus either the hotel confirmation number, or the booking email together with the last 4 digits of the card used to book. An email address alone is not enough. An optional check-in date can narrow repeat stays.

TDQS

A4.3/5.0
Behavior4/5

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

Annotations already establish the read-only and non-destructive nature, so the description adds value by stating that the tool returns the confirmation number and booking summary in conversation, and that an email alone will not resolve a booking. This is useful behavioral context beyond the annotations, without contradicting them.

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 compact and front-loaded: purpose and return value come first, followed by precise identification requirements. Every sentence contributes useful guidance, and there is no redundant filler.

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 six-parameter read-only lookup with an output schema and annotations, the description covers purpose, output mode, and the necessary parameter combinations. The only notable gap is that it does not explicitly route the agent between this tool and the similar get_booking sibling when a confirmation number is already available.

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?

Although the schema describes each parameter individually, the description contributes a critical constraint the schema does not encode: the user must supply the full name plus either confirmation_number or email together with last_four_card, and email alone is explicitly invalid. This pairing requirement is essential for correct invocation and goes well beyond property-level documentation.

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 resource (reservation) and the operation (look up), and adds the framing 'by verifying the guest's identity,' which helps separate it from simple retrieval siblings like get_booking. It does not explicitly name or contrast sibling tools, so it stops short of the strongest possible differentiation.

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 invocation context: full name plus either a confirmation number or email with last-four-digits, and explicitly warns that an email alone is not sufficient. It gives an agent concrete criteria for when this tool will succeed, though it does not mention alternatives such as get_booking or resend_confirmation for cases where the confirmation number is already known.

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

resend_confirmationResend ConfirmationAInspect

Resend a hotel reservation confirmation email. Use either the confirmation number from a successful lookup_booking call, or the guest's full name and email address when they do not know their confirmation number, card last four, or check-in date. The email contains the hotel confirmation number the guest can then use with lookup_booking or cancel_booking. Recovery requests never reveal whether a reservation matched. The confirmation is sent only to the email address already on the booking record; there is no recipient override. Email changes are handled at https://stayker.com/service.

ParametersJSON Schema
NameRequiredDescriptionDefault
emailNoGuest email address. Used only to find a match; confirmation is sent only to the email address already on file.
last_nameNoGuest last name. Required with first_name and email when the confirmation number is unavailable.
first_nameNoGuest first name. Required with last_name and email when the confirmation number is unavailable.
confirmation_numberNoHotel confirmation number. Use this after a verified lookup.

TDQS

A4.9/5.0
Behavior5/5

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

The description discloses key behavioral traits beyond annotations: recovery requests never reveal whether a reservation matched (privacy behavior), the confirmation is sent only to the existing email on the booking record with no recipient override, and email changes are handled externally. This adds meaningful context that annotations (readOnlyHint=false, destructiveHint=false) do not convey.

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 compact and front-loaded with the core action, then provides the two usage paths, privacy behavior, and recipient constraint in a logical order. Every sentence earns its place; no filler or redundancy.

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 the tool's complexity (two alternative invocation paths, privacy-sensitive behavior, no required parameters), the description covers all essential decision points: how to identify the guest, what happens when no match is found, where the email goes, and where to handle email changes. The output schema exists, so return values need not be described.

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?

Schema description coverage is 100%, so the baseline is 3. The description adds value by explaining the relationship between parameters: confirmation_number is the primary path, while first_name, last_name, and email are the alternative path when the confirmation number is unknown. It also clarifies that email is used only to find a match, not as a recipient override, which is not fully explicit in the schema.

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

Purpose5/5

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

The description states a specific verb and resource ('Resend a hotel reservation confirmation email') and clearly distinguishes this from siblings like lookup_booking and cancel_booking by explaining the confirmation email's role. It also clarifies the two invocation paths (confirmation number vs. guest details), making the tool's purpose unmistakable.

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

Usage Guidelines5/5

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

The description explicitly says when to use each parameter path: use the confirmation number from a successful lookup_booking call, or use full name and email when the guest does not know their confirmation number, card last four, or check-in date. It also states the email is sent only to the address on file and points to a URL for email changes, giving clear context and exclusions.

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

search_hotelsSearch HotelsA

A4.2/5.0
Behavior4/5

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

Annotations already declare readOnlyHint and non-destructive behavior. The description adds useful context beyond annotations: results are nightly rates, guests pay the hotel directly, hotels issue their own confirmation numbers, and loyalty points apply. This helps the agent understand expected behavior without contradicting the schema or annotations.

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 front-loaded with the core purpose and remains compact. The later sentences about payment, confirmation, and loyalty points are slightly beyond what is needed to invoke the tool, but they are brief and provide useful domain context.

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 the 100% parameter schema coverage, existing output schema, and annotations indicating a read-only search operation, the description is complete enough for correct invocation. It clearly conveys the one-room limitation, which is the main non-obvious constraint in the current release.

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 description coverage is 100%, so the schema fully documents all 12 parameters. The description reinforces the key one-room constraint and location/date focus, but it does not add new parameter-level meaning beyond what the schema already provides.

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 starts with a specific action and resource: 'Search hotels by location and dates for exactly one room.' It also states the return type, 'available properties with nightly rates,' and distinguishes itself from booking/lookup siblings by focusing on search only.

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?

It provides clear use context: search by location and dates, with a one-room constraint for the current 1Stay release. It does not explicitly name sibling alternatives like book_hotel or get_hotel_details, but the search-vs-booking distinction is strongly implied and easy to infer.

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

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already establish readOnly=true and destructiveHint=false, so the safety profile is covered. The description adds behavioral detail beyond that: the optional keyword filters by tool category, and omitting it yields the full list. This is enough for an agent to anticipate the tool's behavior.

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, and no filler. Every clause adds necessary information about behavior or parameter semantics.

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?

This is a simple, read-only discovery tool with one optional parameter and an output schema present. The description fully covers selection and invocation needs; nothing important is missing.

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?

Schema coverage is 100%, and the schema already describes the keyword parameter with examples. The description adds meaning by clarifying the default behavior when the parameter is absent, which is not captured in the schema.

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

Purpose5/5

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

The description uses a specific verb and resource: 'List available 1Stay hotel booking tools.' It clearly differentiates this meta-tool from sibling tools like book_hotel, cancel_booking, and search_hotels, which perform operations rather than list them.

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

Usage Guidelines4/5

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

It gives clear context on how to use the optional keyword filter and the default behavior when no keyword is supplied ('absence of a keyword returns all tools'). It doesn't explicitly contrast with sibling alternatives, but the description makes the tool-discovery purpose unambiguous.

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