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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions ranking by total cost and usefulness for cost comparison, but lacks details on how the ranking is performed (e.g., based on current pricing, includes hidden fees), what data sources are used, whether it's real-time or cached, or any rate limits or authentication needs. This leaves significant behavioral aspects unclear for a tool that could involve complex calculations.

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 highly concise and front-loaded, consisting of two sentences that directly state the tool's purpose and utility. Every sentence earns its place by clearly communicating core functionality without redundancy or unnecessary details, making it efficient and easy to parse.

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 of cost comparison (involving calculations, data sources, and potential variability) and the lack of annotations and output schema, the description is incomplete. It does not explain what the output looks like (e.g., ranked list format, cost units), how results are derived, or any limitations (e.g., regional pricing differences). For a tool with no structured output and behavioral gaps, this falls short of providing sufficient 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%, so the schema already documents all parameters thoroughly. The description adds marginal value by implying that 'input_tokens' and 'output_tokens' are used to calculate total cost, but it does not provide additional semantics beyond what the schema descriptions state (e.g., how tokens relate to cost, default behaviors beyond schema defaults). Baseline 3 is appropriate as the schema does the heavy lifting.

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 ('Rank AI models by total cost') and resources ('AI models'), and distinguishes it from siblings by focusing on comparative cost analysis rather than retrieving raw pricing data or other operational information. It explicitly mentions the use case ('finding the cheapest model'), making the purpose distinct and actionable.

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 ('Useful for finding the cheapest model for your use case'), which implies it's for cost optimization scenarios. However, it does not explicitly state when not to use it or name alternatives (e.g., 'get_api_pricing' for raw pricing data), leaving some guidance gaps compared to explicit sibling differentiation.

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?

With no annotations provided, the description carries the full burden of behavioral disclosure. It describes the tool's function and filtering capability, but does not disclose behavioral traits like rate limits, authentication needs, error handling, or pagination behavior. The description is accurate but lacks operational context.

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, consisting of two concise sentences that directly state the tool's purpose and filtering capability. Every sentence earns its place with 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?

Given the tool's moderate complexity (2 parameters, no annotations, no output schema), the description is complete enough for basic understanding but lacks details on return values, error conditions, or operational constraints. It covers the core functionality but does not fully compensate for the absence of annotations and 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 both parameters ('limit' and 'filter') with descriptions. The description adds minimal value beyond the schema by mentioning filtering by 'model or provider name', but does not provide additional syntax, format details, or usage examples 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 the tool's purpose with specific verbs ('Get current API pricing') and resources ('AI models tracked by tickerr.ai'), including what pricing information is provided ('input/output cost per 1M tokens'). It distinguishes from siblings like 'compare_pricing' by focusing on retrieval rather than comparison.

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 ('Filter by model or provider name'), but does not explicitly state when not to use it or name alternatives. It implies usage for retrieving pricing data rather than comparing it, but lacks explicit exclusions or sibling tool comparisons.

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?

With no annotations provided, the description carries the full burden of behavioral disclosure. It states what the tool does but lacks details on behavioral traits such as whether it's read-only, requires authentication, has rate limits, or what the output format might be. For a tool with no annotations, this is a significant gap in 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, efficient sentence that front-loads the core purpose and includes essential details without any wasted words. It's appropriately sized for the tool's complexity and structured to convey key information concisely.

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 (1 optional parameter, no output schema, no annotations), the description is minimally adequate. It covers the purpose and parameter context but lacks completeness in behavioral transparency and usage guidelines, which are important for effective tool invocation by an AI 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?

The input schema has 100% description coverage, with the 'category' parameter well-documented. The description adds value by listing example categories ('LLM APIs, coding assistants, image generation, etc.') beyond the schema's generic examples, but it doesn't provide additional semantic context like default behavior or usage constraints. Baseline 3 is appropriate as the schema does most of the work.

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 ('Find') and resource ('best free plans across AI tools'), and it specifies the grouping by categories. However, it doesn't explicitly distinguish this tool from sibling tools like 'compare_pricing' or 'get_api_pricing', which might also involve pricing or plan information, leaving some ambiguity about its unique role.

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 when to prefer this over sibling tools such as 'compare_pricing' or 'get_api_pricing', nor does it specify any prerequisites or exclusions for usage, leaving the agent to infer context from 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?

With no annotations provided, the description carries full burden for behavioral disclosure. It describes the data source and temporal scope, but lacks critical behavioral details such as authentication requirements, rate limits, pagination behavior, error handling, or what the return format looks like (especially important without an output schema). The description provides basic context but misses key operational traits.

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, well-structured sentence that efficiently communicates purpose, scope, and source without unnecessary words. It is front-loaded with the core action and resource, and every element (temporal range, data source) adds value. No wasted verbiage.

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 (2 parameters, no annotations, no output schema), the description is partially complete. It covers what the tool does and its scope well, but lacks details on behavioral aspects (e.g., response format, error cases) and doesn't compensate for the absence of annotations or output schema. Adequate for basic understanding but with clear gaps for reliable 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?

Schema description coverage is 100%, so the schema fully documents both parameters (slug with examples, limit with default/max). The description adds no additional parameter semantics beyond what's in the schema—it doesn't explain slug format further, clarify limit behavior, or provide usage examples. Baseline 3 is appropriate when schema does all the work.

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 ('Get historical incidents') and resource ('incidents (outages, degradations) for any AI tool'), with precise temporal scope ('from the last 90 days') and data source ('Sourced from 26 official provider status pages'). It distinguishes from sibling tools like get_tool_status (likely current status) by focusing on historical 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 implies usage context through temporal and source constraints (last 90 days, official status pages), but does not explicitly state when to use this tool versus alternatives like get_tool_status or other siblings. No exclusions or prerequisites are mentioned, leaving some ambiguity about appropriate use cases.

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?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key traits: it's a read operation (implied by 'Get'), requires authentication ('via authenticated API calls'), has a refresh rate ('Updated every 5 minutes'), and covers specific models. It does not mention rate limits, error handling, or output format, but provides substantial context beyond basic purpose.

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 front-loaded with the core purpose, followed by supporting details (metrics, model coverage, update frequency, authentication). Every sentence adds value without redundancy, and it is appropriately sized for a tool with one parameter and no annotations, making it efficient and easy to parse.

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 (performance metrics with one parameter), no annotations, and no output schema, the description is largely complete. It covers what the tool does, scope, update frequency, and authentication needs. However, it lacks details on output format (e.g., structure of returned data) and error cases, which would enhance completeness for an agent invoking it.

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 'provider' documented as 'Provider name — currently "anthropic" (Claude models). More providers coming soon.' The description adds no additional parameter details beyond this, such as default behavior if omitted or future provider examples. Baseline 3 is appropriate as the schema adequately covers the 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 the tool's purpose with specific verbs ('Get real-time API inference performance') and resources ('AI models'), listing the exact metrics (TTFT, throughput, success rate) and model coverage (all 6 Claude models). It distinguishes itself from siblings like compare_pricing or get_incidents by focusing on performance metrics rather than pricing, incidents, or other operational aspects.

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 obtain real-time performance metrics for AI models, specifically Claude models. It mentions the update frequency (every 5 minutes) and authentication requirement, which helps set expectations. However, it does not explicitly state when not to use it or name alternatives among siblings (e.g., using get_rate_limits for rate-related info instead).

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?

No annotations are provided, so the description carries the full burden of behavioral disclosure. It describes what information is retrieved but lacks details on permissions, rate limits of this tool itself, error handling, or response format, which are critical for a tool that queries system 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 purpose and lists key metrics without unnecessary words, making it easy to parse and understand 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?

For a simple read-only tool with one parameter and no output schema, the description is adequate in stating what it does but incomplete as it lacks behavioral details like response structure or error cases, which are important given the tool's focus on system limits.

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 'slug' well-documented in the schema. The description adds no additional parameter semantics beyond implying the slug identifies AI tools, which is already covered, so it 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?

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?

No annotations are provided, so the description carries the full burden. It states the tool lists tools but does not disclose behavioral traits such as whether the list is paginated, sorted, or includes metadata like categories or descriptions. For a list operation with zero annotation coverage, this is a significant gap in 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, efficient sentence that front-loads the key action ('List all 42+ AI tools') and provides relevant examples without waste. Every word earns its place, making it highly concise and well-structured.

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

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

Given the tool's simplicity (0 parameters, no output schema, no annotations), the description is adequate but has clear gaps. It specifies what is listed but not the format or structure of the output, which is important since there's no output schema. For a list tool, more detail on return values would improve completeness.

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 0 parameters with 100% coverage, so no parameter documentation is needed. The description appropriately does not discuss parameters, and the baseline for 0 parameters is 4, as it avoids unnecessary information while being complete for this case.
