Average 3.9/5 across 3 of 3 tools scored.
Each tool has a distinct and clear purpose: fetching a specific deal by ID, listing all active deals, and searching by category. There is no overlap that would cause confusion for an agent.
All tool names follow a consistent verb_noun pattern using snake_case (get_deal_by_id, list_active_deals, search_deals_by_category). The verbs (get, list, search) are appropriate for each operation and maintain a predictable structure.
With only 3 tools, the server is on the lower end of reasonable scope. While the tools cover essential read operations for a flash sales domain, the small count suggests limited functionality, though it is not overly sparse.
The server lacks write operations (create, update, delete) and any merchant-related functionality, making it incomplete for full lifecycle management. The read-only surface is a notable gap for a deals platform.
get_deal_by_idGet deal by idAInspectLook up a single active deal by its Heartly internal id (UUID).
| Name | Required | Description | Default |
|---|---|---|---|
| id | Yes | Heartly internal deal id (UUID). |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description bears full responsibility. It discloses that the tool retrieves an active deal (read-only) but does not mention error handling (e.g., not found), authentication needs, or rate limits. The description adds 'active' context beyond the schema but lacks deeper behavioral details.
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 a single, front-loaded sentence with no unnecessary words. It efficiently conveys the tool's purpose and key constraint (active deal).
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 simple lookup with one parameter and no output schema, the description is fairly complete. It specifies the identifier and the scope ('active'), which covers the core functionality. It could explicitly mention the return format (e.g., full deal object), but this is implied.
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 100%, and the schema already describes the parameter as 'Heartly internal deal id (UUID).' The description adds no significant new meaning beyond confirming it is an internal UUID. Per guidelines, with high schema coverage, baseline 3 is appropriate.
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 looks up a single active deal by its Heartly internal UUID. The verb 'look up' and resource 'single active deal' are specific, and the identifier is precisely defined, distinguishing it from siblings like 'list_active_deals' and 'search_deals_by_category'.
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 when you have a specific UUID for a deal, and the sibling tool names suggest alternatives for listing or searching. However, it does not explicitly state when to use this tool versus alternatives or include any exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
list_active_dealsList active dealsAInspectList currently active flash-sale deals from verified Heartly merchants. Returns deals sorted by ending soonest. Filters are optional and combinable.
| Name | Required | Description | Default |
|---|---|---|---|
| country | No | ISO 3166-1 alpha-2 country code. Filters to merchants whose shipping_countries include this code, plus merchants who ship worldwide. | |
| category | No | Top-level product category, e.g. "fashion", "beauty", "electronics". | |
| min_discount_pct | No | Minimum discount percentage. Only return deals at or above this value. | |
| ending_within_hours | No | Only return deals ending within this many hours from now. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. Discloses sorting and filter combinability, but lacks info on response structure, pagination, rate limits, or authentication needs. Insufficient for a list tool with no output schema.
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?
Two sentences, each serving a distinct purpose: first states core functionality, second adds sorting and filter flexibility. No wasted words.
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 no output schema, description should explain return fields. It only says 'Returns deals sorted by ending soonest' without specifying fields or structure. Missing pagination, limits, or response format, but adequately addresses param usage.
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 100% with clear descriptions for all 4 parameters. Description adds only that filters are optional and combinable, which is already implied. Baseline score of 3 as description provides minimal extra value.
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?
Clearly states verb 'list', resource 'active flash-sale deals', scope 'from verified Heartly merchants', and sorting. Distinguishes from sibling tools by focusing on active deals with ending-soonest order.
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?
Mentions filters are optional and combinable, implying flexible usage. However, no explicit guidance on when to use vs. sibling tools like search_deals_by_category, which could also use category filter.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
search_deals_by_categorySearch deals by categoryAInspectSearch active deals filtered by category. The category argument is required. Other filters (country, min_discount_pct, ending_within_hours) are optional.
| Name | Required | Description | Default |
|---|---|---|---|
| country | No | ISO 3166-1 alpha-2 country code. Filters to merchants whose shipping_countries include this code, plus merchants who ship worldwide. | |
| category | Yes | Top-level product category, e.g. "fashion", "beauty", "electronics". | |
| min_discount_pct | No | Minimum discount percentage. Only return deals at or above this value. | |
| ending_within_hours | No | Only return deals ending within this many hours from now. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided; description is simple and implies a read-only search with no side effects. It does not disclose potential behaviors like pagination, ordering, or limits, but given the straightforward nature, a 3 is appropriate.
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?
Two concise sentences with no wasted words. Efficiently communicates purpose and parameter requirements.
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 mention return format or pagination. With 4 parameters and simple functionality, it is adequate but could be more complete by noting response structure.
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%; the description adds minimal value beyond stating required vs optional. Baseline 3 is correct as schema already explains each parameter.
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 'Search active deals filtered by category', specifying the verb and resource. It distinguishes from siblings 'get_deal_by_id' and 'list_active_deals' by requiring a category filter.
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?
States that 'category' is required and other filters are optional, providing clear parameter usage guidance. However, it does not explicitly compare to siblings or specify when to use this tool over 'list_active_deals'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
