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

Annotations indicate destructiveHint=true, but the description does not explain what makes this operation 'destructive' (e.g., overwriting existing coupons, irreversible changes). No mention of side effects, error states, or authorization needs.

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?

Single sentence, no fluff, direct. However, it is overly terse for a tool with 9 parameters and complex discount logic.

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 complexity (9 parameters, discount logic, no output schema) and annotations hinting at destructiveness, the description is insufficient. Missing context on return value, idempotency, code conflict handling, and impact on existing records.

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 detailed descriptions for all 9 parameters. The description adds no additional meaning beyond 'Create a store coupon', so 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 'Create a store coupon' clearly states the action (create) and resource (store coupon). However, it does not differentiate from sibling tool 'create_discount_giftcard', leaving ambiguity for the agent.

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?

No guidance on when to use this tool versus alternatives like create_discount_giftcard, nor any prerequisites or constraints (e.g., code uniqueness, permission requirements).

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?

The description says 'Create', which implies an additive, non-destructive operation, but the annotations set destructiveHint=true, creating a contradiction. The description does not add any behavioral information beyond what annotations already provide, and the mismatch undermines transparency.

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, concise sentence that immediately conveys the tool's purpose. It is well-front-loaded, though it could benefit from additional context without becoming verbose.

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 creation tool with three required parameters and no output schema, the description is adequate but minimal. It does not mention expected outcomes or distinguish between similar sibling tools.

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?

With 100% schema coverage, the baseline is 3. The description adds no extra meaning beyond the schema's parameter descriptions, which already define name, currency, and initial_credit.

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 'Create a store gift card' clearly states the action and resource. It differentiates from sibling 'create_discount_coupon' by mentioning 'gift card' versus 'coupon', but does not explicitly highlight the distinction or context.

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?

No guidance on when to use this tool versus alternatives like create_discount_coupon or update_discount_giftcard. The description lacks any context about prerequisites or side effects.

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 this as read-only, non-destructive, and open-world, covering the safety profile. The description adds 'paginated' which is valuable behavioral context not in annotations, indicating the response will be paginated rather than returning all categories at once. However, it doesn't describe response format, error conditions, or rate limits.

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 at just four words. Every element earns its place: 'Get' (action), 'store categories' (resource), and '(paginated)' (key behavioral trait). No wasted words or redundant information.

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 read-only list tool with good annotations and full schema coverage, the description is minimally adequate. However, without an output schema, the description doesn't explain what the response contains (category objects with what fields) or pagination details (how to interpret page numbers, total counts). The 'paginated' mention helps but doesn't provide complete context.

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%, with all three parameters well-documented in the schema. The description doesn't add any parameter-specific information beyond what's in the schema. The baseline of 3 is appropriate when the schema provides complete parameter 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 clearly states the verb ('Get') and resource ('store categories'), making the purpose understandable. It distinguishes from siblings like 'get_products' by specifying categories rather than products, but doesn't explicitly differentiate from other category-related tools (none exist in siblings). The addition of '(paginated)' is helpful context.

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?

No guidance is provided about when to use this tool versus alternatives. While siblings include various 'get_' tools for different resources (products, customers, payments), the description doesn't mention when to retrieve categories specifically or whether this is the primary way to access category data. The pagination mention implies large datasets but doesn't provide usage context.

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, openWorldHint=true, and destructiveHint=false, so the agent knows this is a safe, non-destructive read operation with open-world semantics. The description adds context about pagination, sorting, and filtering, which are useful behavioral traits not covered by annotations. However, it doesn't disclose rate limits, authentication needs, or error conditions.

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, efficient sentence that front-loads the core purpose and key capabilities without any wasted words. It's appropriately sized for the tool's complexity and structured to convey essential information quickly.

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's moderate complexity (4 parameters, no output schema), the description covers the main behavioral aspects (pagination, sorting, filtering). With annotations providing safety and openness context, and schema covering parameters fully, the description is reasonably complete. However, it lacks details on return format or error handling, which could be helpful for an agent.

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%, with all parameters well-documented in the schema. The description mentions pagination, sorting, and date range filtering, which aligns with the parameters but doesn't add significant meaning beyond what the schema provides. The baseline score of 3 is appropriate given the 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 verb ('Get') and resource ('customers'), making the purpose evident. It also mentions key capabilities (paginated, sortable, filterable by date range), which helps distinguish it from other list operations. However, it doesn't explicitly differentiate from sibling tools like 'get_products' or 'get_servers' beyond the resource type.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, when not to use it, or compare it to sibling tools like 'get_payments' or 'get_subscriptions' for related data needs. Usage is implied by the resource name only.

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, destructiveHint=false, and openWorldHint=true, so the agent knows this is a safe, read-only operation with potentially large result sets. The description adds 'paginated' which provides important behavioral context about how results are returned, but doesn't mention rate limits, authentication requirements, or what specific coupon data is returned. No contradiction with annotations exists.

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 extremely concise at just four words plus parentheses, with zero wasted language. It's front-loaded with the core purpose ('Get store coupons') and includes the critical behavioral detail ('paginated') efficiently. Every element earns its place without redundancy.

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 read-only tool with good annotations (readOnlyHint, openWorldHint) and full schema coverage, the description provides the minimum viable information. However, without an output schema, the description doesn't explain what coupon data is returned (e.g., codes, values, expiration dates) or the pagination structure. The combination of annotations and description gives adequate but incomplete context for the agent.

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?

With 100% schema description coverage, both parameters (page and max_page) are fully documented in the schema with descriptions, types, defaults, and constraints. The description adds no additional parameter semantics beyond implying pagination exists, which is already evident from the parameter names. This meets the baseline expectation when schema coverage is complete.

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 'Get store coupons (paginated)' clearly states the action (get) and resource (store coupons), with the parenthetical '(paginated)' providing important scope information. It distinguishes from siblings like create_discount_coupon and update_discount_coupon by focusing on retrieval rather than modification. However, it doesn't explicitly differentiate from get_discount_giftcards which retrieves a different resource type.

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 no guidance on when to use this tool versus alternatives. There's no mention of prerequisites, when this tool is appropriate versus other retrieval tools like get_products or get_customers, or any context about what 'store coupons' encompasses. The agent must infer usage from the tool name alone.

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 cover read-only, non-destructive, and open-world hints, but the description adds valuable context: it explicitly states the tool is paginated, which isn't indicated in annotations. This clarifies behavioral traits like result chunking and the need for iterative calls, enhancing transparency beyond the structured data.

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 extremely concise—a single, front-loaded sentence with zero wasted words. It efficiently conveys the core purpose and a key behavioral trait (paginated), making it easy for an agent to parse quickly.

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's low complexity (read-only list operation), rich annotations, and full schema coverage, the description is minimally adequate. However, it lacks output details (no schema provided) and doesn't clarify scope or filtering, leaving gaps in completeness for effective agent use.

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?

With 100% schema description coverage, the input schema fully documents both parameters (page and max_page with defaults and constraints). The description adds no additional meaning about parameters, so it meets the baseline of 3 without compensating for any gaps.

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 states the action ('Get') and resource ('store gift cards'), but it's vague about scope and lacks sibling differentiation. It doesn't specify whether this retrieves all gift cards, active ones, or a filtered subset, and doesn't distinguish it from tools like 'get_discount_coupons' or 'update_discount_giftcard'.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, context (e.g., for viewing gift cards vs. coupons), or exclusions, leaving the agent to infer usage from the name alone among many sibling tools.

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, openWorldHint=true, and destructiveHint=false, covering safety and data scope. The description does not contradict these, and while it adds no behavioral details beyond annotations, the annotations themselves are comprehensive. No additional context like rate limits or auth needs is provided, but the annotations sufficiently inform the agent's expectations.

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 extremely concise with just two words, 'Get payment', which directly states the tool's purpose without any fluff. It is front-loaded and wastes no space, though this brevity contributes to gaps in other dimensions like purpose clarity and usage guidelines.

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's simplicity (single parameter, high schema coverage, no output schema) and rich annotations, the description is minimally adequate. However, it lacks details on return values or error handling, which are not covered by annotations or schema, leaving some contextual gaps for the agent despite the straightforward nature of the tool.

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%, with the single parameter 'id' fully documented in the schema as 'The payment ID to retrieve.' The description adds no parameter information beyond what the schema provides, so it meets the baseline score of 3 where the schema handles parameter documentation adequately.

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 'Get payment' is a tautology that restates the tool name without adding meaningful context. It specifies the verb 'get' and resource 'payment', but lacks any distinguishing details about scope, format, or differentiation from sibling tools like 'get_payments' (plural). This minimal statement provides only basic intent without specificity.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention prerequisites, context, or exclusions, nor does it differentiate from the sibling 'get_payments' tool. Without any usage instructions, the agent must infer appropriate scenarios solely from the tool name and schema.

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, openWorldHint=true, and destructiveHint=false, covering safety and scope. The description adds pagination behavior and filtering capability, which provides useful context beyond annotations. However, it doesn't describe response format, error conditions, or rate limits.

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, efficient sentence that front-loads the core functionality ('Get payments') and immediately adds key behavioral details (paginated, optionally filtered). Every word earns its place with zero redundancy.

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 read-only list tool with good annotations and full schema coverage, the description adequately covers core behavior. However, without an output schema, it doesn't describe what the payments data looks like (structure, fields), leaving a gap for the agent to understand return values.

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%, with all parameters well-documented in the schema. The description mentions pagination and optional user identifier filtering, which aligns with the schema but doesn't add significant semantic value beyond what's already in parameter descriptions.

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

The description provides minimal guidance with 'paginated, with optional filters', but offers no explicit advice on when to use this tool versus alternatives like 'get_product_by_id' or 'get_categories'. No context on prerequisites or exclusions is given.

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, openWorldHint=true, and destructiveHint=false, indicating this is a safe, read-only operation that may not return all possible data. The description adds no behavioral context beyond this—it doesn't mention authentication needs, rate limits, error conditions, or what happens if the ID doesn't exist. With annotations covering the core safety profile, the description adds minimal value but doesn't contradict them.

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 extremely concise at three words, with zero wasted language. It's front-loaded with the core action ('Get'), though this brevity comes at the cost of completeness. Every word earns its place by directly stating the tool's function.

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 lack of an output schema and the tool's role in a system with multiple server-related tools (e.g., 'get_servers', 'get_server_commands'), the description is incomplete. It doesn't explain what a 'server' represents in this context, what data is returned, or how this tool fits into the broader workflow. The annotations help but don't compensate for these gaps.

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 input schema has 100% description coverage, with the single parameter 'id' documented as 'The ID of the server to retrieve.' The description adds no additional meaning about the parameter, such as ID format, valid ranges, or examples. Baseline 3 is appropriate since the schema fully covers parameter 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 'Get server by ID' is a tautology that restates the tool name without adding meaningful context. While it clearly indicates a retrieval action ('Get'), it doesn't specify what 'server' means in this domain or distinguish this tool from sibling tools like 'get_servers' (plural). The purpose is vague beyond the basic verb-noun structure.

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 no guidance on when to use this tool versus alternatives.

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 action ('Get') and resource ('servers'), and specifies pagination, which is a key behavioral trait. However, it doesn't differentiate from sibling tools like 'get_server_by_id' or 'get_server_commands', which target specific servers or server commands respectively, so it misses full sibling distinction.

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 no guidance on when to use this tool versus alternatives. For example, it doesn't mention using 'get_server_by_id' for a specific server or 'get_products' for different resources, leaving the agent to infer usage from context alone.

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 indicate read-only, non-destructive, and open-world behavior, which the description doesn't contradict. The description adds value by specifying 'general information,' implying a broad overview rather than detailed data, which helps contextualize the tool's scope 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.

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

The description is a single, clear sentence with no wasted words. It's front-loaded and efficiently conveys the core purpose, making it easy for an agent to parse quickly.

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's simplicity (0 parameters, no output schema) and rich annotations, the description is adequate but minimal. It lacks details on what 'general information' includes or the response format, which could be helpful for an agent to understand the output better.

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?

With 0 parameters and 100% schema coverage, the schema fully documents the lack of inputs. The description adds meaning by implying the tool retrieves a default set of information without needing parameters, which is appropriate and compensates for the simplicity.

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 'Get general information about the store' clearly states the verb ('Get') and resource ('store'), making the purpose understandable. However, it's vague about what 'general information' entails and doesn't differentiate from sibling tools like 'get_store_theme' or 'get_categories', which also retrieve store-related data.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, context for usage, or exclusions, leaving the agent to infer based on tool names alone without explicit direction.

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?

The annotations already cover key behavioral traits (read-only, non-destructive, open-world), so the bar is lower. The description adds minimal context by specifying 'general information,' but it doesn't elaborate on what that includes, rate limits, or authentication needs. No contradiction with annotations exists.

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, efficient sentence that directly states the tool's purpose without any fluff or unnecessary details. It's front-loaded and wastes no words, making it easy for an agent to parse quickly.

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's simplicity (0 parameters, no output schema) and rich annotations, the description is adequate but minimal. It lacks details on what 'general information' entails or how it differs from similar tools, which could help the agent use it more effectively in context.

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?

With 0 parameters and 100% schema description coverage, the schema fully documents the lack of inputs. The description doesn't need to add parameter details, and it appropriately avoids redundancy, earning a baseline score for tools with no parameters.

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 a specific verb ('Get') and resource ('general information about the store theme'), making it understandable. However, it doesn't explicitly distinguish this from sibling tools like 'get_store_info', which might also provide theme-related information, so it doesn't reach the highest score.

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 no guidance on when to use this tool versus alternatives. With siblings like 'get_store_info' that might overlap in functionality, there's no indication of context, prerequisites, or exclusions, leaving the agent to guess based on tool names alone.

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 read-only, open-world, and non-destructive behavior. The description adds valuable context beyond this: it specifies pagination, filtering capabilities, and the 'recurring only' constraint, which are not covered by annotations. No contradictions with annotations exist.

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, efficient sentence that front-loads key information: the action, resource, and main features (paginated, filterable, recurring only, by user identifier). There is no wasted verbiage, and every word contributes to understanding the tool's 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?

Given the tool's complexity (filtering, pagination) and lack of an output schema, the description provides good context but could benefit from mentioning return format or pagination details. Annotations cover safety aspects, and the description adds operational context, making it largely complete for a read-only tool.

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 fully documents all parameters. The description mentions filtering by user identifier and recurring subscriptions, which aligns with parameters but doesn't add significant semantic detail beyond what the schema provides. Baseline 3 is appropriate given 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 verb ('Get') and resource ('subscriptions'), and specifies key characteristics: paginated, filterable, recurring only, and by user identifier. This distinguishes it from sibling tools like get_payments or get_products, which handle different resources.

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 clear context for when to use this tool: to retrieve subscriptions with specific filtering options (recurring, by user). However, it doesn't explicitly state when not to use it or name alternatives among siblings, such as get_payments for payment-related data instead of subscriptions.

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 a write operation (readOnlyHint=false) and non-destructive behavior. The description adds 'mark delivered actions,' but doesn't disclose side effects, idempotency, or whether this can be called multiple times. Consistent with annotations, 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.

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

The description is a single sentence, very concise, and includes the core action. However, it is slightly cryptic due to the parenthetical; it could be clearer without adding length.

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?

Despite the complex nested schema and no output schema, the description provides minimal context. It doesn't explain the purpose of 'delivered actions,' when this endpoint is used, or what the response looks like. The agent must rely heavily on the schema and external knowledge.

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 detailed descriptions and examples for both parameters. The description adds no extra meaning beyond the schema; the parenthetical 'mark delivered actions' is implicit. 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 the action ('Update server commands') and the resource ('server commands'), but the parenthetical 'mark delivered actions' adds nuance. It distinguishes from siblings which are mostly getters and discount tools, though not explicitly.

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?

No guidance on when to use this tool versus alternatives, no prerequisites, and no context about the 'delivered actions' concept. The agent has to infer usage from the name and schema alone.

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 indicate destructiveHint=true and openWorldHint=true, but description adds no behavioral details beyond the implication of 'update'. No mention of side effects, partial updates vs full replacement, or required permissions.

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?

Single sentence is concise but under-specified. It conveys purpose without extra information, but lacks structure for clarity.

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 provided, so description should clarify return value or side effects. It does not. For a destructive update tool with many siblings, more context is needed.

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 full parameter descriptions. The tool description adds no additional semantics beyond the schema. Baseline of 3 is appropriate as the schema already documents parameters.

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?

Description states 'Update a store coupon' which clearly specifies the action (update) and resource (store coupon). It distinguishes from sibling tools like create_discount_coupon and update_discount_giftcard by resource type.

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?

No guidance on when to use this tool versus alternatives (e.g., create_discount_coupon for creation, or get_discount_coupons to retrieve existing coupons). No prerequisites or context 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 indicate destructiveHint=true, but the description does not explain what destructive actions occur (e.g., overwriting fields, deleting previous values). Also, openWorldHint=true suggests the schema may be non-exhaustive, but this is not communicated. The description adds no behavioral context beyond the verb 'Update'.

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, concise sentence with no unnecessary words. It is front-loaded and efficient.

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's mutation nature, destructive hint, and lack of output schema, the description fails to explain return values, side effects, or the meaning of 'update' in this context. It is insufficient for an agent to fully understand the tool's behavior.

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 input schema covers 100% of parameters with descriptions, so the description adds no further semantic value. It does not elaborate on parameter usage or constraints beyond what the schema provides.

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 'Update a store gift card', using a specific verb and resource. It implicitly distinguishes from siblings like 'create_discount_giftcard' and 'update_discount_coupon', but lacks details on the scope of update (e.g., which fields).

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?

No guidance on when to use this tool versus alternatives like 'create_discount_giftcard' or 'get_discount_giftcards'. No preconditions or exclusions are mentioned.

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