Server Quality Checklist

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

Latest release: v2.3.0
Disambiguation4/5
Tools cover distinct bioinformatics tasks with detailed descriptions, but some overlap exists (e.g., find_protein vs get_protein_info, pathway_analysis vs network_enrichment). Most tools have clear, differentiated purposes.
Naming Consistency5/5
All tools use underscore_separated lowercase names following a verb_noun pattern (e.g., get_gene_info, search_pubmed). A few tools include version suffixes or omit verbs, but overall pattern is highly consistent.
Tool Count3/5
32 tools is high for a single server, but the broad scope of bioinformatics (genes, proteins, drugs, variants, etc.) justifies the count. However, the number feels slightly heavy and could be streamlined.
Completeness4/5
The server covers a wide range of bioinformatics workflows including gene/protein lookup, variant analysis, drug repurposing, clinical trials, and network enrichment. Minor gaps exist (e.g., no GO enrichment), but overall coverage is comprehensive.
Average 3.7/5 across 32 of 32 tools scored. Lowest: 2.8/5.

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

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true. Description adds context about merge semantics and MCP resource usage, but does not detail specific behavioral nuances like session persistence boundaries or side effects of each action.
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?
Single sentence is concise and lists key capabilities. Could be more front-loaded with the core purpose, but no wasted words.
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 with 9 parameters, 12 actions, and no output schema, the description is too sparse. It does not detail each action's behavior, expected inputs, or outcomes, leaving critical gaps for the agent.
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 description coverage is 100%, so the baseline is 3. The description does not add additional parameter-level context beyond what the schema already provides.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose3/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description lists multiple capabilities (entity resolution, graph inspection, save/restore, export, planning) but fails to define a single specific verb+resource. It distinguishes from sibling tools as a session management tool, but the purpose is broad and lacks focus.
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 sibling tools like find_protein or pathway_analysis. No 'when to use' or 'when not to use' rationale, leaving the agent to infer from the tool's broad functionality.
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?
Annotations already declare readOnlyHint=true and idempotentHint=true, so the safety profile is clear. However, the description adds no additional behavioral context, such as whether results are cached, computational cost, or prerequisites (e.g., genome availability). It merely states the covered steps.
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 a single sentence that encapsulates the tool's scope without redundant wording. It is front-loaded with the key term 'CRISPR workflow' and then enumerates steps, making it efficient. Slightly longer due to listing all steps, but still 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?
Given the complexity (13 parameters, 1 required) and the absence of an output schema, the description is minimally adequate. It explains the high-level purpose but does not guide which parameters correspond to which step or provide examples beyond the schema example. The schema's examples partly compensate.
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?
With 100% schema description coverage, the baseline is 3. The description does not add meaning beyond the schema, but the schema itself is thorough, including enums and defaults. The parameter 'action' is implicitly linked to the workflow steps, but this is already in the 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 clearly lists the CRISPR workflow steps (design, scoring, off-target, base editing, repair), making the tool's purpose explicit. However, it does not differentiate from sibling tools like 'run_blast' or 'variant_analysis', which are distinct but could be confused without context.
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., 'run_blast' for sequence alignment). The description lacks context for tool selection or exclusions.
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?
Annotations already declare readOnlyHint=true and idempotentHint=true, indicating safe, idempotent behavior. The description adds 'structured claim decomposition' but does not elaborate on query behavior, evidence sources, or result format. No contradiction with annotations.
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?
Single sentence is concise but uses jargon ('structured claim decomposition', 'relation-specific database evidence') that reduces clarity. The description could be more informative without being verbose.
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?
Despite good annotations and schema, the description lacks explanation of output format, how decomposition works, or how to interpret evidence. For a complex verification tool, this 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 100% (baseline 3). The description adds no information about the parameters (claim, context_gene, max_evidence_sources) beyond what is in the 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 clearly states the tool verifies biological claims using structured decomposition and database evidence, which distinguishes it from sibling tools focused on specific analyses (e.g., pathway_analysis, variant_analysis). However, 'structured claim decomposition' and 'relation-specific database evidence' are somewhat vague.
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 (e.g., search_pubmed, get_gene_info). The description does not mention when not to use it or provide context for selecting it over siblings.
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?
Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, covering safety and idempotency. The description adds no further behavioral context (e.g., data source freshness, failure modes, or that it combines two databases). Given the strong annotation coverage, a 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that communicates core capabilities without fluff. However, it lacks front-loading of the most critical information (the action parameter) and could benefit from a more structured format (e.g., listing actions).
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 tool has no output schema and 6 parameters with multiple actions, yet the description does not explain what the tool returns or describe the 'auto' action. This leaves the agent without crucial context about invocation results and action selection, making the description incomplete.
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 100%, so all parameters have descriptions in the schema. The tool description does not add additional meaning beyond what the schema provides (e.g., it mentions actions but does not clarify which action to use for which scenario). Per guidelines, baseline is 3 with high coverage.
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 lists three specific capabilities (search KEGG, retrieve genes for a pathway, assemble Reactome plus KEGG context) tied to actions in the schema. It clearly identifies the tool as a merged pathway workflow, but the term 'merged pathway workflow' is somewhat vague and the 'auto' action is not described, slightly reducing clarity.
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. With 30+ sibling tools including 'network_enrichment' and 'get_gene_info', explicit when-to-use or when-not-to-use guidance is missing, limiting the agent's ability to select the correct tool.
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?
Annotations already indicate readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, covering safety. The description adds minimal behavioral context beyond stating the data source and scope. It does not describe pagination, result format, or any side effects, but the annotations largely compensate.
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 a single sentence, concise and to the point. It front-loads the essential information (source and what is retrieved). No extraneous words. Could include a brief note about the optional parameter, but overall 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?
For a simple tool with 2 parameters and no output schema, the description is mostly adequate but lacks details about the return format, data fields, or necessary credentials. Users unfamiliar with the GWAS Catalog may need more context. The example in input schema helps, but the description itself is thin.
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 description coverage is 100%: both gene_symbol and max_results are described in the schema. The description does not add any parameter information, but the schema already explains them adequately. Baseline score of 3 is appropriate.
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 it retrieves genome-wide significant associations from the NHGRI-EBI GWAS Catalog for a given gene. It uses specific resource (GWAS Catalog) and outcome (associations), but lacks an explicit verb like 'search' or 'retrieve'. It differentiates from siblings by specifying the data source, but not exhaustively.
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 get_gene_disease_associations or find_protein. The description does not mention prerequisites, exclusions, or when not to use it. The context from sibling tool names implies a niche, but explicit guidance is missing.
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?
Annotations already declare readOnlyHint=true and idempotentHint=true. The description adds the specific data source (FDA labels) and the type of check, but does not mention limitations or output behavior. No contradiction with annotations.
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?
Single, clear sentence without redundancy. Front-loaded and appropriately sized for the tool's simplicity.
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 tool with two parameters and no output schema, the description is mostly adequate but lacks explanation of what 'interaction context' means in the output (e.g., severity, management). A minor gap.
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 100%, so both parameters are described. The description repeats 'primary drug' and 'co-medications' without adding format constraints or conventions. Baseline 3 applies.
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 the tool checks FDA label interaction context between a primary drug and co-medications. The verb 'Check' and resource 'FDA label interaction context' are specific. It distinguishes from siblings like drug_safety and pharmacogenomics_report.
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 alternatives like drug_safety. The description implies use for interaction context but lacks 'when to use' or 'when not to use' statements.
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?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, so the description does not need to repeat these. It adds the context 'CPIC-style' and 'PGx evidence', which is useful but minimal. No additional behavioral traits (e.g., rate limits, auth) are disclosed, but the annotation coverage is adequate.
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 a single, clear sentence that is front-loaded with the core action. It is concise without being overly terse, but there is room to add a bit more context without becoming 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?
Given the tool has 3 parameters, no output schema, and good annotations, the description is adequate but not rich. It does not explain what the output looks like or what 'CPIC-style' entails exactly. More detail on the report structure would improve completeness.
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 description coverage is 100%, so the input schema already documents all parameters. The description does not add meaning beyond what is in the schema (e.g., 'Drug of interest', 'Optional gene to force into the report'). Baseline 3 is appropriate as the description offers no extra clarification.
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: 'Summarize CPIC-style pharmacogenomic genes and supporting PGx evidence for a drug.' It uses a specific verb ('Summarize') and resource ('pharmacogenomic genes and evidence'), and the mention of 'CPIC-style' distinguishes it from general drug info tools like drug_interaction_checker or drug_safety.
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 is provided. The description does not mention alternatives or context for selecting this tool over siblings such as drug_safety, get_drug_targets, or drug_interaction_checker. The agent must infer usage from the tool name and description alone.
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?
Annotations already declare readOnlyHint=true, and description adds mode context. However, it does not disclose limitations, input conflicts, or output behavior beyond schema info.
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?
Two clear sentences that are front-loaded and efficient, with no wasted words.
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?
With 12 parameters and no output schema, the description is too sparse. It does not cover parameter semantics for complex inputs like pocket_residues or the interaction between multiple sequence types.
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 100%, so baseline 3. The description adds minimal meaning beyond schema by explaining modes, but does not clarify parameter interactions (e.g., protein_sequences vs uniprot_accession).
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 it is a Boltz-2 structure workflow with two modes (structure and protein_ligand), distinguishing it from sibling tools like get_alphafold_structure. However, it could be more specific about the output format.
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 instructs which mode to use for multimolecular vs. protein-ligand docking, but lacks explicit guidance on when not to use this tool or comparisons to alternatives like AlphaFold.
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?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the description adds minimal safety context. It does clarify the data source (cBioPortal) and scope (TCGA), which provides some behavioral context beyond annotations.
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?
A single, front-loaded sentence that concisely conveys the tool's purpose with no unnecessary words. Excellent structure for quick comprehension.
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 three parameters and no output schema, the description is too brief. It lacks information about the return format, pagination, rate limits, or how results are structured, leaving significant gaps for the agent.
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 description coverage is 100%, so the schema already fully documents parameters. The description adds no additional meaning beyond what's in the schema, meeting the baseline 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?
Description clearly states the tool queries cBioPortal for cancer mutation frequencies across TCGA cohorts. This is specific and distinguishes it from sibling tools like bulk_gene_analysis or variant_analysis.
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 vs alternatives or when not to use it. While the context implies use for mutation frequencies, it lacks any caveats or comparative advice.
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?
Annotations already declare readOnlyHint, idempotentHint, and other traits. The description adds minimal behavioral context beyond 'surface approved drugs,' but does not contradict annotations. More detail on algorithm or data source would improve 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 two sentences long with no extraneous information. It is front-loaded and efficiently conveys the tool's purpose.
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?
Despite good annotations, the description lacks details on output format, scoring or prioritization of candidates, and limitations. For a discovery tool with no output schema, more context is needed to fully inform an agent.
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 description coverage is 100%, so the schema already documents all parameters. The description does not add new meaning beyond the schema, 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 uses a specific verb 'surface' and resource 'approved drugs' with a clear context of activity against a target/disease. It effectively distinguishes from sibling tools like drug_interaction_checker and get_drug_targets.
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 usage for drug repurposing but does not provide explicit guidance on when to use this tool versus alternatives. No exclusions or when-not scenarios are mentioned.
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 claims the tool auto-indexes into the session knowledge graph, contradicting the readOnlyHint annotation, which indicates no side effects. This is an annotation contradiction.
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 two sentences, front-loads key content types, and includes a usage hint. Every word is informative with no 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?
The description lists the types of data returned (function, domains, etc.), compensating for the lack of an output schema. However, the contradiction reduces confidence in behavioral 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?
The schema fully covers the single parameter with an example. The description adds value by recommending reviewed accessions (P/Q/O prefix), providing guidance 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 the tool retrieves a full UniProt Swiss-Prot entry with specific content types (function, domains, PTMs, GO terms, disease links, sequence), distinguishing it from sibling tools like get_gene_info and find_protein.
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 advises preferring reviewed accessions (P/Q/O prefix) but does not specify when to use this tool versus alternatives like find_protein or get_gene_info. Usage context is implied but not explicit.
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?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, which adequately inform about safety and idempotency. The description adds no additional behavioral insights (e.g., rate limits, data freshness). It repeats the purpose but does not expand beyond 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single sentence that is concise and front-loaded, clearly communicating the tool's purpose without extraneous words.
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 tool has a simple interface with 3 parameters and no output schema. The description covers the core function but omits what the output looks like (e.g., list of pathways with scores, network nodes). The input example partially compensates. Overall, it is adequate but could mention return format for completeness.
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 description coverage is 100% as all three parameters have descriptions in the input schema. The tool description does not add any extra meaning or nuances beyond what is already in the schema, so the baseline score of 3 is appropriate.
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 uses a specific verb 'summarize' and identifies distinct resources (Reactome pathways, STRING network hubs) applied to a gene set. It clearly distinguishes from sibling tools like 'pathway_analysis' which likely performs standard enrichment, and 'find_protein' which focuses on individual proteins.
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 the tool is for summarizing network-level insights, but it does not explicitly state when to use it versus alternatives such as 'pathway_analysis' or 'verify_biological_claim'. No when-not or clear context for selection is provided.
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?
Annotations already indicate readonly, non-destructive, idempotent behavior. The description adds that the method is 'heuristic' and 'likely,' informing the agent about approximate nature. This adds value beyond annotations, though more detail on limitations would be beneficial.
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 a single, well-structured sentence that conveys the essential purpose without any extraneous words. It is appropriately front-loaded and efficient.
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?
Despite no output schema, the description does not explain what the tool returns (e.g., cell-type fractions with confidence scores). The example in the schema helps but is not in the description. Given the tool's complexity and three parameters, the description should cover return format.
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 covers all three parameters with clear descriptions, achieving 100% coverage. The tool description does not add additional meaning beyond the schema, so baseline score of 3 is appropriate.
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 performs deconvolution of bulk RNA-seq data into cell-type fractions, using a marker-based heuristic. This verb+resource combination is specific and distinguishes it from sibling tools like bulk_gene_analysis.
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, nor does it mention prerequisites or scenarios where it is inappropriate. The agent is left to infer 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?
Annotations already indicate readOnlyHint=true and destructiveHint=false. The description adds the workflow nature (generation vs scoring) but does not disclose any additional behavioral traits such as resource usage, API costs, or limitations. The bar is lowered due to annotations, but still basic.
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 single sentence that covers the core functionality. It could be front-loaded with an action verb but is efficient for the main purpose.
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?
Despite having 10 parameters and no output schema, the description is extremely brief. It does not explain what the tool returns, how to interpret results, or any necessary context for operation. The agent lacks guidance on expected output format.
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?
With 100% schema description coverage, the schema already documents all 10 parameters. The description adds value by explaining the functional difference between the two modes (generate vs score), but does not elaborate on other parameters like num_tokens or temperature, which are self-explanatory in 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?
Description clearly states it is an Evo2 DNA workflow with two distinct modes: generate and score. It separates generation from scoring, which distinguishes it from sibling tools that are focused on analysis, not DNA sequence generation.
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?
Provides explicit instructions on when to use each mode via the 'mode' parameter. However, it does not mention any prerequisites, exclusions, or alternatives to guide the agent in choosing this tool over others.
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?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. The description adds the 'merged' nature, suggesting aggregation from multiple FDA sources. However, it does not disclose other behavioral traits such as rate limits, data freshness, or how the merged workflow is coordinated. The description adds marginal value beyond annotations.
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 a single sentence that front-loads the main purpose and enumerates the core actions. Every phrase contributes to understanding, with no fluff. It is optimally concise for a multi-action tool.
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?
Despite the schema covering parameters 100%, the description fails to explain how the various actions work, what the output looks like, or how to combine them in a workflow. The openWorldHint suggests external data, but no output schema or description of return format is provided. For a tool with 9 parameters and multiple modes, the description is too short to give a complete picture, leaving significant gaps for an agent to infer.
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 description coverage is 100%, so the baseline is 3. The description does not add any parameter-specific information beyond what the schema already provides. It merely lists the high-level workflow steps, which are mapped to the 'action' parameter's enum. No additional semantic context for parameters like 'serious_only' or 'age_group' is given.
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 is a merged FDA drug-safety workflow covering four specific tasks: adverse-event search, signal detection, label review, and head-to-head comparison. This directly distinguishes it from sibling tools like drug_interaction_checker and the many gene/sequence tools, as it uniquely addresses multi-step drug safety analysis.
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 the tool is for combined drug-safety tasks but does not explicitly state when to use it versus alternatives like drug_interaction_checker. The context signals (sibling list) and the name 'drug_safety' provide enough cues for an agent to select it for safety workflows, but a brief note on exclusion would improve clarity.
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?
Annotations (readOnlyHint, idempotentHint, etc.) already indicate safety and idempotency. The description adds context about auto-indexing into a knowledge graph, which is beyond what annotations provide. No contradictions.
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?
Two sentences efficiently convey purpose and a behavioral detail. The second sentence about auto-indexing is somewhat extraneous but not harmful.
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?
Covers data sources but omits return value structure or pagination behavior. Without an output schema, the agent lacks details on what fields are returned, which is a notable gap for a retrieval 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?
Schema has 100% description coverage for both parameters (gene_symbol, max_results) with clear details like HGNC and defaults. Description does not add further parameter semantics beyond listing datatypes, so baseline 3 is appropriate.
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 it retrieves Open Targets gene-disease evidence across 6 specified datatypes, making it distinct from sibling tools like get_gene_info or search_gwas_catalog.

Behavior4/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds context about the workflow steps (ACMG, frequency, ClinVar, splice, reporting) and implies a read-only analysis. No contradictions with annotations.
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?
Single sentence that front-loads the key purpose ('Merged variant-interpretation workflow'). Efficient but could slightly expand on key steps without losing conciseness.
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 complexity (7 parameters, no output schema), the description is adequate for understanding the main purpose but does not explain return values or behavior after execution. Lacks details on output format or next steps.

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 100% and all parameters are well-described in the schema. The description adds general context about the tool's output but does not provide specific additional meaning for the parameters beyond what the schema includes.
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 'summarize', the resource 'candidate binding sites', and the data sources 'UniProt functional-site annotations plus AlphaFold confidence context'. It effectively distinguishes this tool from siblings like get_alphafold_structure or find_protein.
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 usage for summarizing binding sites but does not explicitly state when to use this tool vs. alternatives, nor does it provide when-not-to-use guidance or mention prerequisites.
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?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, openWorldHint=true, so the safety profile is clear. The description adds the behavioral trait of 'auto-indexes drug→disease treatment edges', which provides extra context beyond annotations. No contradictions.
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?
Two sentences that are concise and front-loaded. First sentence states the core functionality and filters; second sentence adds a notable feature. No wasted words.
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 4 parameters, good annotations, and no output schema, the description covers the core purpose and a distinguishing feature. It lacks explicit return format details, but the schema examples partially compensate. Overall adequate for a search 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?
Schema description coverage is 100%, so the schema already documents all parameters adequately. The description does not add new parameter-specific meaning but reinforces the concept of trial filters. Baseline 3 is appropriate.
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 searches ClinicalTrials.gov with filters for status, phase, interventions, enrollment, eligibility. It distinguishes from sibling tools (e.g., search_pubmed, get_gene_info) by focusing on clinical trials, and the explicit mention of 'drug→disease treatment edges' adds specificity.
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 finding clinical trials but does not provide explicit when-to-use or alternatives. However, the context of sibling tools (none of which are clinical trial search) makes the purpose clear, and the example in the schema provides usage context.
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?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safe read-only nature is clear. The description adds that the search is 'PubChem-backed' and uses a threshold, which provides context beyond annotations. However, it does not discuss rate limits, data freshness, or limitations.
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 a single sentence of 11 words, front-loading the key information ('PubChem-backed structural similarity search'). Every word is meaningful and there is no wasted content.
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 has 4 parameters and no output schema, the description tells what it does and the input types. It is mostly complete for a search tool with rich annotations, though it could hint at the return format (e.g., list of similar compounds with scores).
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 description coverage is 100%, so the schema already documents all parameters. The description adds minimal extra meaning beyond what the schema provides (e.g., mentioning 'compound name or SMILES string' maps to query and smiles, but the schema already has descriptions). Per rules, baseline is 3 when coverage is high.
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 performs a 'structural similarity search' using 'PubChem' from 'a compound name or SMILES string'. The verb 'search' and resource 'structural similarity' are specific, and it distinguishes from sibling tools which focus on other bioinformatics tasks.
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 usage for finding similar compounds but provides no explicit guidance on when to use this tool versus alternatives (e.g., when to use a different search or analysis tool). There is no 'when not to use' or 'see also' mention.
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?
Beyond annotations (readOnly, idempotent, openWorld), description adds that the tool auto-indexes edges into a knowledge graph and specifies the types of values returned, providing useful behavioral context. No contradictions with annotations.
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?
Two concise sentences: first lists key outputs, second mentions an important side-effect (auto-indexing). Every part adds value, no filler.
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?
Description is adequate for a simple query tool with good annotations, but missing explicit details about output structure (e.g., list of objects with fields like IC50, Ki). Given no output schema, more detail 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 already describes both parameters well (100% coverage). Description adds value by clarifying that the output includes specific activity types and metadata, helping interpret the results expected from the parameters.
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?
Description clearly states it retrieves ChEMBL drug-target activities (IC50, Ki, Kd, assay types, approval status) for a given gene, distinguishing it from siblings that focus on other aspects like drug interactions or disease associations.
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 usage for obtaining drug-target activity data but does not explicitly state when to use this tool versus alternatives like drug_interaction_checker, leaving the agent to infer context from sibling names.
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?
Annotations already indicate readOnlyHint=true, destructiveHint=false, idempotentHint=true, openWorldHint=true. The description adds behavioral context about the analysis process, scoring methodology, and return matrix format, which goes beyond annotations without contradiction.
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 two sentences long, front-loads the core action, and provides essential detail on differential mode in the second sentence. No superfluous 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 five parameters, no output schema, and complexity of panel analysis, the description covers the main purpose and differential mode. However, it lacks details on output format specification (e.g., matrix structure) and constraints like gene list limits mentioned in the schema.
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 100% with detailed parameter descriptions. The description adds high-level context about differential mode and scoring but does not provide additional semantic detail for individual parameters beyond what is in 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 the tool's purpose: analyzing one or two gene panels in parallel and returning a cross-gene comparison matrix. It also distinguishes differential mode with pathway and disease enrichment ranking, which differentiates it from sibling tools like pathway_analysis or get_gene_disease_associations.
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 explains two usage modes (single panel vs differential) and when to use each. It does not explicitly state when not to use it or name alternatives, but the context from sibling tools implies its niche for bulk comparison.
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?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, covering safety. The description adds value by specifying the generated output (links and context), providing behavioral context beyond what annotations offer.
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 a single, well-structured sentence with no extraneous words. It efficiently communicates the tool's 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 low complexity, clear description, complete schema, and detailed annotations, the description is mostly complete. However, the term 'locus context' could be interpreted as ambiguous, and there is no mention of return format or that it generates URLs.
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 has 100% description coverage so baseline is 3. The description adds context that the tool works for a gene or genomic interval, tying the parameters together, which is helpful beyond the per-parameter 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 the verb 'generate' and the resources 'genome-browser links and locus context', and it distinguishes from sibling tools by specifying the output type (links and context) rather than analysis or other operations.
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?
No explicit when-to-use or when-not-to-use guidance is provided. The usage context is implied by the description but not compared to alternatives, which limits the agent's ability to decide when to use this tool over 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?
Annotations already declare read-only, idempotent, open-world. The description adds that results are auto-indexed into the session knowledge graph and lists return fields. No contradiction; adds useful 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.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Three concise sentences that front-load the primary purpose, then add capabilities and return info. No fluff; every sentence adds 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?
For a read-only search tool with no output schema, the description covers purpose, features, return fields, and a side effect. It does not mention pagination or limits, but is otherwise complete.
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 100% with detailed parameter descriptions. The description does not add additional meaning beyond what the schema provides, thus 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 searches PubMed for scientific literature, specifies it supports full NCBI query syntax, and lists return fields. It distinguishes from sibling tools like search_clinical_trials by being specifically for PubMed literature.
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 literature searches and mentions advanced query features, but does not explicitly compare to sibling tools or provide when-to-use guidance. The context is clear though not exclusive.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
