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 only states 'convert' but does not disclose whether it calls an external API, has rate limits, or requires authentication. The description is minimal and lacks behavioral 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 a single sentence with no wasted words, but it is too short for a tool with two parameters and potential complexity. It sacrifices necessary detail for brevity.

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 role in a clinical query pipeline, the description lacks sufficient context about input parameters, output format (though output schema exists), and how it fits with sibling tools. It is not complete enough for an agent to reliably invoke 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 description does not mention either of the two parameters. With 0% schema description coverage, the description should compensate but does not. The 'filters' parameter is unexplained, and 'natural_language_question' is only implied by the main sentence.

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 converts a natural-language clinical question into a PubMed-ready query, specifying both the action (convert) and the domain (clinical question to query). It distinguishes from sibling tools which perform search, retrieval, or summarization.

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 explicit guidance on when to use this tool versus alternatives like search_pubmed. The description implies it is a preprocessing step but does not state it should be used before search tools. There is no mention of when not to use it.

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, the description should disclose behavioral traits. It only states the sources checked but does not reveal what happens on failure, API dependencies, rate limits, or side effects. The behavior is opaque.

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 one short sentence (7 words) but omits essential information, making it under-specified rather than concise. It lacks structure and earns its place poorly.

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 has two optional parameters and an output schema, the description does not clarify that a identifier must be provided or what the scope of 'availability' means. Incomplete for effective 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 coverage is 0% and the description does not mention the parameters (doi, pmid) at all. It fails to explain that at least one is needed or their required formats, leaving the agent without guidance.

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 checks PMC and Unpaywall for legal full-text availability, specifying the sources and action. It distinguishes from siblings like fetch_pmc_full_text and search tools.

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 does not provide any guidance on when to use this tool versus alternatives (e.g., when to check availability vs. directly fetching full text). No when-not-to-use or context distinctions are 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?

No annotations are provided, so the description carries the full burden. It only notes that the extraction is 'rough' but offers no details on error handling, input validation, or output behavior beyond what the output schema might provide.

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?

A single sentence of 12 words directly conveys the tool's purpose without any extraneous information. It is perfectly front-loaded and concise.

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 existence of an output schema, return values are covered. However, the description lacks context on when this tool should be preferred over siblings like build_clinical_query, and omits any prerequisites or limitations.

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% schema description coverage, the description adds some meaning by specifying the input is 'from an abstract or article passage', clarifying the parameter's domain. However, it does not detail format expectations or constraints.

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 'Extract a rough PICO structure from an abstract or article passage', which is a specific verb (Extract) and clear resource (PICO structure). This clearly distinguishes it from siblings like search_pubmed, fetch_pubmed_articles, and summarize_evidence.

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 such as build_clinical_query or summarize_evidence. The description lacks any when-to-use or when-not-to-use 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?

With no annotations provided, the description carries full burden for behavioral disclosure. It fails to mention what happens if both pmid and pmcid are provided, if none are provided, or any authentication or rate limits. The term 'legal' hints at compliance but is vague.

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 waste. It earns its place by stating the core action and condition, though it could be slightly expanded without harming conciseness.

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 two optional params with no schema descriptions, no annotations, and an output schema that may cover return values, the description is too brief. It fails to explain parameter interaction or fallback behavior, leaving critical gaps 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 coverage is 0%, so the description should explain parameter usage. It only implies pmcid is preferred but does not clarify the role of pmid, whether they are interchangeable, or what happens when both are provided.

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 uses a specific verb ('Fetch') and resource ('legal PubMed Central full-text sections'), clearly distinguishing it from siblings like check_full_text_availability or fetch_pubmed_articles. The condition 'when a PMCID is available' clarifies scope.

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 a PMCID is available but does not explicitly state when not to use it, nor does it mention alternatives like check_full_text_availability for availability checks or fetch_pubmed_articles for non-PMC content.

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 present, so the description must cover behavioral traits. It only lists fields retrieved and omits important details such as required authentication, handling of invalid PMIDs, or return format.

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 lists the fetched fields. It is concise but could be improved by front-loading the verb and input specification.

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 presence of an output schema and siblings, the description is incomplete. It fails to specify that the tool returns metadata only, how many PMIDs can be processed, or the order of results. The missing details hinder effective 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?

The parameter 'pmids' has 0% schema description coverage, and the tool description provides no explanation of its purpose, format, or constraints. The agent receives no guidance on what values to supply.

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 specifies the verb 'fetch' and the resource 'PubMed articles' and lists specific fields retrieved. However, it does not explicitly mention that the input is a list of PMIDs, which is important for clarity.

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 siblings like search_pubmed or fetch_pmc_full_text. The description lacks context for tool selection.

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 full responsibility for behavioral disclosure. It mentions 'NCBI elink' hinting at an external API call, but does not disclose rate limits, the definition of 'related', error handling, or whether the operation is read-only. Critical safety information is missing.

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 very short (one sentence) and front-loaded with the core action, but it sacrifices necessary detail for brevity. It is concise but under-informative for a tool with two parameters and no annotation support.

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 0% schema description coverage, lack of annotations, and presence of multiple sibling tools, the description is insufficiently complete. It does not mention how 'max_results' affects behavior, what the output structure is (despite an output schema existing), or any constraints like valid PMID format.

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 0%, meaning the parameters have no descriptions in the schema. The description adds no semantic value beyond the parameter names. 'pmid' is self-explanatory, but 'max_results' is left ambiguous (e.g., maximum number of results? upper bound? pagination?).

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 ('find') and resource ('related PubMed articles'), and specifies the mechanism ('through NCBI elink'). It effectively distinguishes this tool from siblings like search_pubmed (which finds articles by query) and fetch_pubmed_articles (which fetches by PMID).

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 PMID and want related articles, but it does not provide explicit guidance on when to use this tool over alternatives (e.g., search_pubmed for broader topics) or any prerequisites or limitations.

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, the description carries the full burden. It accurately indicates a stateless computation (ranking and explaining), which suggests no side effects. However, it does not detail return format or potential limitations, but the core behavior is clear.

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 conveys the essential purpose without unnecessary detail. Every word earns its place.

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, does the description cover enough for an agent to succeed on first attempt?

The tool combines multiple sub-tasks and has an output schema, but the description does not explain the output format or ranking criteria. It is incomplete given the tool's complexity.

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 0%. The description does not add any meaning to parameters 'clinical_question', 'filters', or 'max_results' beyond their names. This is insufficient for a tool with three 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 function: building a query, searching PubMed, fetching articles, and returning ranked summaries. It distinguishes from simpler siblings like 'search_pubmed' (just search) and 'fetch_pubmed_articles' (just fetch).

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?
