Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.1.4
Disambiguation5/5
Each tool is clearly distinguished by source (e.g., arxiv, biorxiv, crossref) and action (search_, download_, read_). There is no ambiguity even among similar sources because the prefix uniquely identifies the platform.
Naming Consistency5/5
All tool names follow a uniform verb_noun pattern: action_source (e.g., search_arxiv, download_pubmed, read_semantic). The convention is strictly maintained across all 57 tools, making it predictable and easy to parse.
Tool Count2/5
With 57 tools, the set is overly large for the server's purpose. Many sources have separate tools for search, download, and read even when download/read are not supported, resulting in redundant error-returning tools. A more concise design would combine variants or use fewer tools.
Completeness4/5
The surface covers a broad range of academic sources, offering search, download, and read for most. However, some sources (e.g., crossref, pubmed, ssrn) have non-functional download/read tools that merely return errors, which is a minor gap. The unified search_papers tool partially mitigates this.
Average 3.7/5 across 57 of 57 tools scored. Lowest: 1.9/5.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully disclose behavior. It fails to transparently state that the tool returns an error message and does not actually read papers. The contradiction between the stated purpose and actual return is misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is somewhat concise but poorly structured. The contradictory nature ('read' vs 'unsupported') makes the information less efficient. It could be clearer and more front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description does not fully explain the tool's behavior. It omits that the tool is non-functional or returns an error. With no output schema provided, the agent lacks complete information to decide whether to use it.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds meaning to both parameters: paper_id is explained as 'PubMed ID (PMID)' and save_path is noted as 'unused', which goes beyond the bare schema. Given 0% schema coverage, this is helpful.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose1/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'Read and extract text content from a PubMed paper' but the Returns section reveals that direct paper reading is not supported, creating a contradiction and making the purpose unclear.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. Sibling tools include numerous read_* and search_* tools, but the description does not differentiate or offer usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full behavioral burden. It discloses that dblp does not support direct PDF download and that the function returns a message. However, it does not clarify whether any network request is made or if the function is essentially a no-op. The actual behavior (no download) is partially transparent but could be more explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is relatively short and uses a clear note and parameter list. However, it is not optimally structured: the key contradiction between the first sentence and the note undermines conciseness. A more upfront disclosure of the tool's limitation would improve clarity without increasing length.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's misleading name and purpose, the description fails to provide complete context. It does not explain why this tool exists, what alternative tools should be used for PDF downloads, or what the meaningful use case is. The output schema is implied but not leveraged to add completeness. The description leaves the agent with insufficient information to decide to invoke this tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds meaning for both parameters: 'paper_id' is identified as a dblp identifier, and 'save_path' is described as a directory with a default. Since schema coverage is 0%, the description compensates well, but the semantics for 'save_path' are misleading because the tool does not actually save anything. Overall, it adds value but suffers from the tool's behavioral contradiction.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose1/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description first states 'Download PDF for a paper from dblp' but then immediately contradicts itself by noting dblp doesn't provide direct PDF access and that the function returns an informative message. This makes the purpose misleading: the tool does not download PDFs, despite its name and initial claim.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description mentions that dblp lacks direct PDF access, providing some context for when not to use this tool. However, it does not explicitly guide the agent on when to use this tool versus alternatives (e.g., download_scihub), nor does it suggest any alternative actions. The guidance is implicit and insufficient.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description says 'Attempt to read' but the return value states reading is not supported, effectively indicating failure. This is misleading; the tool's true behavior (returning a failure message) is not disclosed upfront. No annotations exist to mitigate this.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with a clear structure: purpose, Args, Returns. No extraneous text. However, the content is misleading, which reduces effectiveness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that an output schema exists, the description does not elaborate on the return value beyond 'str: Message indicating...'. The tool is non-functional as a reader, and the description does not clarify its limitations or offer alternatives, making it incomplete for practical use.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds meaning beyond the input schema: it explains paper_id as an OpenAlex paper ID and save_path as a directory for saving, including a default. Since schema coverage is 0%, this is valuable clarification.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'Attempt to read and extract text content from an OpenAlex paper,' but the return message indicates 'direct paper reading is not supported natively,' creating confusion about the tool's actual purpose. It is not a tautology, but it is vague and contradictory.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 sibling read tools (e.g., read_arxiv_paper). No when-not-to-use or alternative suggestions are provided. The misleading implication that it can read papers makes the usage context unclear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the tool returns an error message, but the first sentence implies a download capability, misleading the agent. No annotations provided.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short and to the point, but the contradictory first sentence could be reworded for clarity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a tool that always fails, the description does not explain why or what to use instead, leaving the agent without a clear alternative.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description adds value by explaining paper_id and explicitly noting save_path is unused, which the schema does not convey.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose2/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'Download PDF for a paper from SSRN' but immediately contradicts with 'SSRN connector is metadata-only and download is not supported', creating confusion about the tool's actual purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives like download_arxiv or read_ssrn_paper. The note about metadata-only hints at unsuitability but doesn't name a substitute.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It hints at indirect downloads but does not fully explain behavior, such as what the tool actually does (attempts download? returns URL?). The return is only described as an error message, which is misleading for a download tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short but includes a one-line purpose and docstring-style args/returns. It is reasonably concise, though the return line is confusing and could be better structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of many sibling tools, the description is incomplete. It fails to explain the tool's role in the ecosystem, what happens on success, or the actual output beyond an error message. The presence of an output schema (not shown) might mitigate, but the description alone is insufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description compensates by defining paper_id as 'OpenAlex paper ID' and save_path as 'Directory to save the PDF'. This adds basic meaning beyond the schema, but lacks format details for paper_id and usage of default.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Download PDF for a paper from OpenAlex', specifying the verb, resource, and source. However, it mentions reliance on pdf_url rather than direct downloads, which introduces ambiguity about the actual function.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 over the many sibling download sources. The description does not differentiate OpenAlex from others or specify prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must cover behavioral aspects. It only mentions returning a list of paper metadata, but does not disclose rate limits, authentication needs, or any side effects. The read-only nature is implied but not stated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise—two sentences plus an Args section. The purpose is front-loaded. Minor improvement could be separating the args from the main description, but it's well-structured overall.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With an output schema (though not shown), the description needn't detail return values, but it still mentions the return format. Missing usage guidelines and behavioral details make it somewhat incomplete for a search tool with many siblings.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description includes an Args section that adds an example for query ('e.g., 'machine learning') and notes the default for max_results. This adds some value beyond the schema, though it remains relatively basic.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Search academic papers from CORE' which specifies the verb (search) and the resource (academic papers from CORE). Among many sibling tools for different sources, this uniquely identifies the tool's purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 like search_arxiv or search_pubmed. It does not mention when not to use it or any prerequisites.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only states it downloads a PDF. It does not disclose error handling, authentication needs, rate limits, or behavior on missing papers.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Concise and front-loaded with the core purpose, followed by parameter and return descriptions. No wasted words, but could organize args section more cleanly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple download operation and presence of an output schema, the description covers purpose, inputs, and output adequately. Minor gap: no mention of error scenarios.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description partially compensates by explaining paper_id as 'HAL paper identifier' and save_path as directory with default. However, it lacks details like ID format.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Download PDF') and the resource ('paper from HAL'), distinguishing it from sibling download tools for other sources.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 download_scihub or download_with_fallback. Usage is implied only by the source name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description bears full responsibility. It fails to disclose what happens if the paper is not found, any authentication needed, or side effects (e.g., file overwrite behavior). Merely stating the return type is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise at three sentences with a clear Arg/Returns structure, but it is somewhat boilerplate and could be more succinct.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
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 no nested objects, the description adequately covers the basic functionality. However, it could mention overwrite behavior or file size limits to be fully complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description adds meaningful information for both parameters: paper_id is identified as a BASE identifier, and save_path is given a default directory. This compensates well for the schema gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Download PDF for a paper from BASE.', using a specific verb (download) and resource (PDF from BASE). This distinguishes it from sibling tools like download_arxiv which target different sources.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 (e.g., download_with_fallback, read_base_paper). It lacks context about prerequisites or typical scenarios.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that the tool returns a message indicating direct PDF download is not supported, which is a key behavioral trait. However, it uses 'attempt' which implies potential success, creating ambiguity. With no annotations, the description partially carries the burden but could be more explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise with two sentences plus Args/Returns section. It efficiently conveys purpose, parameters, and return behavior. However, the first sentence could be more precise than 'attempt to download' given the actual outcome.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description adequately covers the tool's simple behavior: it always returns a message that download is not supported. With an output schema likely existing (though not shown), the return description is sufficient. For a stub tool, completeness is high.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description explains both parameters: paper_id is a PubMed ID (PMID), and save_path is a directory with default './downloads'. This adds meaning beyond the schema titles, especially since schema description coverage is 0%. The parameter descriptions are clear and directly useful.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states it attempts to download a PubMed paper PDF, identifying the specific resource (PubMed) and action (download). However, the return value contradicts this by indicating direct PDF download is not supported, causing some confusion about the tool's true purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is given on when to use this tool versus alternatives. Among siblings, there are many working download tools for other sources and read tools for PubMed. The description does not warn that this tool will not actually download, leaving the agent without context for decision-making.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavior. It mentions reading and extracting text, but fails to clarify side effects (e.g., whether the PDF is downloaded, cached, or if network access is required), error handling, or what happens if the paper is not found. The description is insufficient for transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, using a single paragraph with clearly structured Args and Returns sections. There is no extraneous information, and the key purpose is stated upfront. It could be slightly more streamlined, but is already very efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the basic purpose, parameters, and return type. However, it lacks important context such as whether the tool downloads papers, handles errors, or requires prerequisites. Given the simplicity of the tool (2 params, 1 required), the gaps are notable, earning a 3.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Despite 0% schema description coverage, the description adds meaning to both parameters: 'paper_id' is described as 'BASE paper identifier' (though vague on format), and 'save_path' is explained as a directory with a default. This provides some guidance but not enough detail for the paper_id format, resulting in a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's action ('Read and extract text content') and the resource ('a BASE paper'). The name 'read_base_paper' combined with the description effectively distinguishes this tool from numerous sibling read_* tools targeting other sources.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not explicitly state when to use this tool versus alternatives (e.g., download_base or other read_* tools). However, the tool name and resource mention 'BASE', which implies it is for BASE papers. The usage context is implied rather than stated, earning a score of 3.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It transparently discloses that the tool returns an error message because SSRN is metadata-only, and that the save_path parameter is unused. This clearly communicates the tool's behavior and limitations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is short and front-loaded, with the main action stated first, followed by a crucial note. The Args and Returns are clearly formatted. However, the first sentence alone is misleading without the note, slightly reducing conciseness effectiveness.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that the tool always returns an error string, the description covers the essential behavior. However, it does not specify the exact error message format or whether other errors (e.g., invalid paper_id) could occur. The output schema is not shown, so the return type is vaguely described.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The description adds meaning to both parameters: paper_id is described as 'SSRN paper identifier' (schema says 'Paper Id'), and save_path is noted as 'Directory where the PDF is/will be saved (unused)'. Since schema description coverage is 0%, the description compensates but the explanations are minimal, lacking format details for paper_id.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states 'Read paper content from SSRN' which clearly identifies the intended action and resource. It immediately follows with a note that the SSRN connector is metadata-only and read is not supported, clarifying that the tool returns an error. This distinguishes it from other read_* tools that actually return content.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no explicit guidance on when to use this tool vs alternatives. While it states that reading is not supported, it does not recommend using download_ssrn or other tools. The note implies this tool is not useful for acquiring content, but fails to direct the user to a viable alternative among siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must cover behavioral traits. It only states that it returns a list of paper metadata, but does not disclose safety (read-only), rate limits, pagination, sorting, or any side effects. This is insufficient for a tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and well-structured, with clear Args/Returns sections. It is front-loaded with the main purpose. No extraneous content, but could be slightly more compact.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 parameters, search operation) and the presence of an output schema (though not detailed), the description covers the essential functionality. However, it lacks details on result format, error behavior, and constraints, making it minimally adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description adds meaning: it explains that 'query' is a search string with an example ('machine learning'), and that 'max_results' controls the number of papers (default 10). This provides useful semantic context beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description 'Search academic papers from CiteSeerX digital library' uses a specific verb ('Search') and names the resource ('CiteSeerX digital library'). Among sibling tools with similar names for different libraries, this clearly distinguishes the tool.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 (e.g., search_arxiv, search_pubmed). It does not mention any context, prerequisites, or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full responsibility for behavioral disclosure. It states only that results are 'List of paper metadata in dictionary format.' It omits details about authentication, rate limits, pagination, or any side effects—critical for an external API call.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise (four lines) and front-loaded with the purpose. It uses a structured Args/Returns format that is easy to parse. However, the Args section largely duplicates schema information, slightly reducing efficiency.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is a simple search with two parameters and an output schema (not shown). The description covers core functionality but lacks details on error handling, empty results, or rate limits. For a tool with many siblings, more context would aid selection.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must compensate. It adds example values for query and explains max_results as 'Maximum number of papers to return (default: 10).' While helpful, it does not specify constraints like allowed length, encoding, or range for max_results, leaving some ambiguity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description opens with 'Search academic papers from Google Scholar,' which clearly states the verb (search), resource (academic papers), and specific source (Google Scholar). Among many sibling search_* tools for different sources, this uniquely identifies its target database.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies use for Google Scholar searches but provides no guidance on when to choose it over siblings (e.g., search_pubmed, search_arxiv). No exclusions or alternatives are mentioned, leaving the agent to infer context from the name alone.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
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 only states that it returns 'List of paper metadata in dictionary format.' No mention of rate limits, pagination, error handling, or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is structured as a docstring with Args and Returns sections. It is clear and organized, though somewhat repetitive of the schema for defaults. Each sentence serves a purpose, but the text could be slightly more concise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a search tool with an output schema present, the description does not need to explain return values in depth. However, it lacks information on pagination, result ordering, or any limitations. It is adequate for basic use but could be more complete.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, meaning the schema has no parameter descriptions. The description adds meaningful context: 'query: Search query string (e.g., 'machine learning'). max_results: Maximum number of papers to return (default: 10).' This compensates for the lack of schema descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Search academic papers from HAL open archive.' It uses a specific verb ('Search') and resource ('academic papers from HAL open archive'), distinguishing it from sibling tools that target other archives (e.g., arXiv, PubMed).
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 like search_arxiv, search_pubmed, etc. The description does not mention any selection criteria or scenarios where HAL is preferred.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It states it returns a list of paper metadata in dictionary format, but omits any side effects, rate limits, authentication requirements, or details about pagination or filtering. The behavioral profile is minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief and front-loaded with the purpose. The Args and Returns sections are clearly structured. However, the Returns line is somewhat vague and could be more specific, but overall it is efficient.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool has 2 parameters and an output schema (though not shown here), the description covers the basics but lacks examples of query syntax or guidance on result handling. It is minimally complete for a simple search tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description must add meaning. It explains 'query' as a search query string with an example, and 'max_results' as maximum number of papers with a default. This adds significant value beyond the schema's type-only definitions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool searches academic papers from PubMed Central (PMC), using a specific verb and resource. This distinguishes it from siblings like search_pubmed which searches PubMed, and search_europepmc which searches Europe PMC.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 search_pubmed or search_europepmc. The description does not provide context for selection or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It only states the return format ('List of paper metadata') without addressing pagination, rate limits, authentication, or sorting. The default max_results is noted but not elaborated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, with a clear purpose sentence followed by structured Args and Returns sections. No redundant information, but the format could be slightly improved by integrating the default value inline rather than in a separate docstring.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity and the presence of an output schema (context signal), the description is adequate for basic usage. However, it lacks information on pagination, error handling, and repository-specific quirks, leaving some gaps for complex queries.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Despite 0% schema coverage, the description adds meaningful semantics: 'query: Search query string (e.g., 'machine learning')' provides a concrete example, and 'max_results: Maximum number of papers to return (default: 10)' clarifies the parameter's behavior. This compensates well for the schema's lack of description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function: 'Search academic papers from Zenodo open repository.' It uses a specific verb (search) and resource (academic papers) and uniquely identifies the repository (Zenodo), distinguishing it from sibling search_* tools for other databases.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 vs. alternatives like search_arxiv or search_base. The description does not mention coverage, advantages, or situations where Zenodo is appropriate.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Lacks behavioral details: no mention of error handling, authentication needs, rate limits, or whether the tool is read-only. Annotations are absent, so description carries full burden but provides minimal context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise (one-line description plus docstring for parameters), no wasted words, front-loaded with purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Adequately covers parameters and return type with output schema, but lacks behavioral context (e.g., error scenarios, idempotency) that would be expected given the absence of annotations.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Adds meaning beyond schema for both parameters: explains paper_id as 'DOAJ paper identifier' and save_path as 'Directory to save the PDF (default: ./downloads)'. Compensates for 0% schema description coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
Clearly states the verb (Download), resource (PDF), and source (DOAJ), distinguishing it from sibling tools targeting other repositories.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs alternatives (e.g., download_with_fallback, read_* tools) or any prerequisites for using it.

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the basic action (read and extract text) but does not specify behavioral traits such as whether it downloads the PDF locally, any side effects, authentication requirements, or rate limits. With no annotations, the description is insufficient for full transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise with two sentences plus parameter bullets. There is no redundancy or unnecessary information, and the structure is front-loaded with the core action.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description covers the basic function and parameter details, but lacks completeness regarding error scenarios, output format intricacies, and the relationship to sibling tools. Given the presence of an output schema (not shown), the return value is partially addressed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Both parameters are explained: paper_id is described as a medRxiv DOI, and save_path is described as a directory with a default value. Since the input schema has 0% description coverage, the description effectively compensates by adding missing meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the verb 'Read and extract' and the resource 'medRxiv paper PDF', and the paper_id parameter specifies it's a medRxiv DOI, distinguishing it from sibling read_*_paper tools for other sources.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 like read_arxiv_paper or download_medrxiv. The agent is left to infer based solely on the tool name, with no explicit usage context or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must cover behavioral traits. It only mentions returns and defaults, but lacks details on API behavior, rate limits, authentication, sorting, or result structure beyond 'dictionary format.'
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With two simple parameters and an output schema, the description is minimally adequate. It covers the core functionality but lacks guidance on return fields (though schema likely covers that) and usage context. Given the sibling set, more context would help.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It explains 'query' with an example and 'max_results' with its default, adding value beyond the schema's type and title. However, it could elaborate on query syntax or limits.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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. Given many search_* siblings for different sources, the agent would need explicit criteria for choosing dblp, which is missing.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should disclose safety, permissions, and side effects. It only states 'Download PDF' and returns path/error, omitting whether this is read-only, auth requirements, or potential issues like 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise: two sentences for description, then structured Args/Returns. Every sentence is necessary and front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple download tool with output schema, the description covers purpose, parameters, and return. Missing explicit mention that file is actually saved (not a link) and error handling, but still adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Despite 0% schema coverage, the description adds meaning: paper_id is described as 'OpenAIRE paper identifier', save_path has default and directory role. It explains the return type. More detail on paper_id format would improve clarity.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description should disclose behavior. It mentions text extraction but omits potential issues like PDF parsing failures, rate limits, or that it may download the PDF (implied by save_path). Unclear if it reads an existing file or always downloads. Insufficient for an agent to anticipate side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Extremely concise: one sentence for purpose, then straightforward Args/Returns sections. No unnecessary words. Front-loaded with the core action. Every sentence provides value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity (2 params, clear purpose) and existence of an output schema (return type stated), the description is mostly complete. However, it lacks error handling context and does not explicitly state whether the PDF is downloaded or assumed present. Still, it covers the main functionality well.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so description adds crucial meaning: paper_id is explained with an example ('2106.12345'), and save_path is described as a directory for saving/reading PDFs with default './downloads'. This goes beyond the bare schema and helps the agent understand parameter usage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it reads and extracts text from an arXiv paper PDF, using a specific verb ('read') and resource ('arXiv paper PDF'). It distinguishes itself from sibling 'read_*' tools by specifying the source (arXiv) and from 'download_arxiv' and 'search_arxiv' by focusing on text extraction. This provides unambiguous purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance on when to use this tool vs other 'read_*' tools (e.g., for different sources) or vs download/search tools. No mention of prerequisites like internet access or paper existence. Lacks context for tool selection among many siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the burden. It clearly states that direct paper reading is not supported and that the tool returns a message to that effect. The behavioral limitation is transparently disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is reasonably structured with Args, Returns, and Note sections. It is front-loaded with the purpose. However, it could be slightly more concise, as the note could be integrated earlier.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simple behavior and lack of annotations, the description covers the key aspects: what the tool does, its limitations, and an alternative action. The return type is mentioned, and the output schema exists (context indicates true). Good completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must add meaning. It explains paper_id as a CrossRef DOI with an example, and save_path as a directory with a default. This adds clarity beyond the bare schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description indicates the tool attempts to read a CrossRef paper but then states it doesn't support direct paper reading. The purpose is clear: to inform the user that CrossRef does not provide paper content. However, the initial phrasing is slightly misleading as it says 'attempt to read' but ultimately returns a failure message.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 the numerous sibling tools that read papers from other sources. The note suggests using the publisher's website instead, but does not name alternative tools. Usage context is not well-defined.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description fully discloses that the tool does not return paper content, only an informative message. It also notes that save_path is unused. This is honest and prevents misuse, though it could mention the nature of the message.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, with each sentence serving a purpose. It uses a clear docstring format with Args and Returns sections, front-loading the key limitation. No redundant text.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the simple tool (2 params, no nested objects, output schema exists), the description covers behavior, unused parameter, and return type. Could be slightly improved by hinting at the message content or suggesting download alternatives, but it is largely adequate.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters3/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description explains paper_id as 'dblp paper identifier' and save_path as 'unused'. This adds some meaning, but the format of paper_id is not specified, and save_path's irrelevance is clearly stated.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose4/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description states the tool attempts to read a dblp paper but immediately clarifies that dblp does not provide direct access, so it returns an informative message. This clearly differentiates it from other read_* tools that may succeed, and avoids false expectations.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
No explicit when-to-use or when-not-to-use guidance. The note about dblp's limitation implies that users should not expect actual content, but it does not suggest alternatives like download_dblp. Sibling tools exist but are not referenced.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries the full burden. It discloses the core read/extract action and save_path side effect, but does not mention caching, network requirements, or error behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is reasonably concise with the core purpose front-loaded. The Args and Returns sections add structure, though slightly verbose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read tool with output schema, the description covers main functionality but misses error handling, format, and prerequisites. Could be more complete given many siblings.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, but the description explains both parameters: paper_id as 'HAL paper identifier' and save_path as directory for saving PDF. This adds meaning beyond the schema names and types.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Read and extract text content from a HAL paper', specifying the verb, resource, and output. It distinguishes from sibling read tools for other sources.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
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 alternative read tools for different sources or when to use download_hal instead. The description assumes the user knows to choose HAL.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It implies a read-only operation but does not disclose potential issues such as rate limits, authentication needs, or behavior when a paper is not found. The multiple identifier formats are useful but insufficient for transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with an Args section and front-loaded purpose. It is reasonably concise for the detail it provides, though the list of paper_id formats could be shortened with a general pattern. No unnecessary sentences.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness3/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the presence of many sibling read_ tools, the description adequately specifies that it works on Semantic Scholar papers. With an output schema present, the return type 'str' is sufficient. However, it lacks information on error handling, prerequisites for using save_path, and when to prefer this over other read tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must compensate. It provides detailed, example-rich explanations for paper_id, covering many accepted formats. The save_path parameter is explained with a default value, though its specific role (downloading/reading PDF) is implicit. Overall, adds significant meaning beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description explicitly states 'Read and extract text content from a Semantic Scholar paper,' with a clear verb and resource. It distinguishes itself from sibling tools (e.g., read_arxiv_paper) by specifying the source.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description thoroughly documents the paper_id formats, which guides correct invocation. However, it lacks explicit guidance on when to use this tool versus alternatives like other read_* tools or download tools, and does not mention prerequisites or limitations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must carry the full burden. It does not disclose behavioral traits like read-only nature, pagination, rate limits, or authentication requirements. The basic function is described, but key behavior is omitted.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise: one sentence for purpose, followed by structured Args and Returns sections. No unnecessary text; every sentence serves a purpose.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's simplicity and the presence of an output schema, the description covers essential usage. It explains inputs and output format. However, it omits nuances like search behavior and field details, which are partially covered by the output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Although the schema has no descriptions (0% coverage), the description adds meaning by explaining each parameter's purpose and provides an example for 'query' and a default for 'max_results'. This compensates well for the schema gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's function: 'Search academic papers from OpenAlex.' It specifies the verb and resource, and distinguishes from siblings like download_openalex and read_openalex_paper.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must bear the full burden. It only states it downloads a PDF and returns the path, but does not disclose authentication requirements, rate limits, error handling (e.g., paper not found), or any side effects. This is insufficient for a download tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is structured in a docstring format with Args and Returns sections. However, it is verbose and could be more concise. The parameter formats are repeated across lines, and the overall length exceeds what is necessary for a simple download tool.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given that an output schema exists (though not shown), the description adequately covers the return path and parameter details. However, it lacks information about error cases, file overwriting behavior, or performance considerations. For a download tool, this is nearly complete but missing some practical context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage, but the description provides extensive parameter details: paper_id lists 7 explicit formats with examples, and save_path has a default. This adds significant meaning beyond the schema's minimal titles.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?

Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description suggests using the DOI to access the paper through the publisher's website as an alternative, but it does not explicitly compare to sibling tools like download_scihub or provide when-to-use guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden. It discloses that the search is limited by category and within the last 30 days, which is critical behavioral information. It could additionally mention pagination or rate limits, but the core behavior is well covered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise: a short purpose sentence, a key limitation note, and structured Args/Returns sections. Every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's moderate complexity (2 params, 1 required, output schema present), the description covers purpose, behavior, parameter usage, and return type adequately. It could slightly improve by mentioning that results are limited to the last 30 days or details about the output format, but it is sufficient.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has 0% description coverage for parameters. The description compensates by explaining the 'query' parameter with concrete examples (like 'infectious_diseases') and restates the default for 'max_results'. This adds meaningful context beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states 'Search academic papers from medRxiv' and explains the specific limitation that the API filters by category name within the last 30 days, not full-text keyword search. This differentiates it from other search_ tools that may support full-text search.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly notes the API's behavior (category filter, 30-day window) and provides example category keywords, indicating when to use the tool. However, it does not explicitly guide users away from using it for full-text search or suggest alternative tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It transparently discloses the fallback sequence, parameter roles, and return value. However, it omits details like rate limits, authentication needs, or potential failures beyond an error message.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise: a single opening sentence stating the fallback strategy, followed by a bullet-like argument list and return info. Every sentence adds value, and the key purpose is front-loaded.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations, 0% schema coverage, 7 params, and an output schema, the description is complete. It covers purpose, all parameters with examples, behavior (fallback chain), and return format, leaving no major gaps.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Given 0% schema description coverage, the description fully compensates by explaining each parameter's purpose (e.g., 'doi: Optional DOI used for repository/unpaywall/Sci-Hub fallback'). It adds meaning beyond the schema's types and defaults.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: it attempts a multi-stage fallback download chain (source-native, OA repositories, Unpaywall, optional Sci-Hub). This distinguishes it from sibling source-specific download tools which lack fallback logic.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for obtaining papers via multiple access points but does not explicitly state when to avoid this tool or list alternative siblings. The fallback chain is clearly outlined, providing context but not exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior5/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses that the tool extracts the first DOI from the query, returns at most one record, and that max_results is kept for consistency with no effect. Return format is described as a list with one dict or empty.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Concise, well-structured with Args and Returns sections. Every sentence adds value without redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The tool is simple, and the description covers all critical aspects: purpose, parameters, behavioral quirks, and output format. No gaps given the context.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description compensates by explaining that 'query' can be a DOI string or text containing a DOI, and that 'max_results' is for API consistency but always returns one record.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it looks up a DOI via Unpaywall and returns OA metadata, distinguishing it from generic keyword searches (e.g., search_arxiv). It specifies the exact resource and action.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines4/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly notes that Unpaywall does not support generic keyword search, guiding when not to use. It does not name direct alternatives but provides clear context for appropriate use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
