Server Quality Checklist

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

Latest release: v2.0.2
Disambiguation4/5
Most tools have clearly distinct purposes, but there is overlap among metadata retrieval tools (get_asset_details, get_analytical_metadata, get_analytical_model, etc.) and query tools (execute_query, query_analytical_data, query_relational_entity, smart_query), which could confuse an agent. However, descriptions help differentiate.
Naming Consistency5/5
All tools follow a consistent snake_case verb_noun pattern (e.g., list_spaces, get_asset_details, create_database_user). No mixing of conventions, making it predictable.
Tool Count3/5
39 tools is on the high side for a single server. While each tool serves a distinct purpose in managing a data platform, the count borders on excessive and could benefit from splitting into smaller, focused sub-servers.
Completeness3/5
The tool set covers major areas like catalog browsing, querying, user management, and task chains. However, missing create/update/delete for spaces and assets, and no data import tools, leaving notable gaps for a comprehensive data platform.
Average 4.3/5 across 39 of 39 tools scored. Lowest: 3.1/5.

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

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden for behavioral disclosure. It mentions automatic identification based on SAP annotations but does not state performance implications, error handling, or whether the operation is read-only. The read-only nature is implied but not 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, front-loading the core purpose. It avoids redundancy but could be slightly more structured, e.g., by listing return fields explicitly. Still, it earns its place 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?
Given the lack of output schema, the description should more fully describe the returned structure (e.g., hierarchy details, field types). It mentions dimensions, measures, hierarchies, and aggregation info but omits details on error conditions or response format, making it incomplete for a metadata 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 coverage is 100% with clear descriptions for all three parameters. The description adds context about the identify_dimensions_measures parameter by linking it to SAP annotations, but this is already in the schema. Baseline score of 3 is appropriate as no significant additional meaning is provided.
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 retrieves CSDL metadata for analytical consumption, including dimensions, measures, hierarchies, and aggregation information. It distinguishes from siblings like get_analytical_model and get_relational_metadata by focusing on analytical schema for BI integration.
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 such as get_analytical_model or list_analytical_datasets. The description lacks context about prerequisites or scenarios where this tool is preferred.
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 description carries full burden. It explains return content and parsing logic (CSDL, annotations, fallback), but omits side effects, authentication requirements, or error handling. Adequate but not comprehensive.
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, no redundancy. First sentence states purpose and output, second sentence provides technical detail. Every word 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 no output schema and no annotations, the description adequately explains the tool's return content (dimensions, measures, entity sets) and parsing methodology. Lacks output format specifics and error scenarios, but sufficient 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 covers 100% of parameters with descriptions. The description adds technical context about returned metadata and parsing approach but does not elaborate on parameter syntax or constraints beyond the schema. 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 it retrieves the OData service document and metadata for a specific analytical model, listing key components (entity sets, dimensions, measures, query capabilities). It distinguishes itself from siblings by focusing on a single model's metadata with parsing details.
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_analytical_metadata or list_analytical_datasets. Lacks context on prerequisites, exclusions, or typical use cases.
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 alone must convey behavioral traits. It describes a read operation but does not disclose potential side effects, permissions required, rate limits, or how missing identifiers are handled. The lack of detail 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?
Two sentences that are front-loaded with the tool's purpose and value. Every sentence adds meaning; no redundant or filler content. Ideal length for quick comprehension.
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 lack of an output schema and moderate complexity, the description covers the key return items (columns, types, mappings, ETL capabilities). It could be slightly more explicit about the output format (e.g., JSON), but overall it provides sufficient context for its straightforward metadata retrieval purpose.
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 input schema covers all three parameters with descriptions (100% coverage). The description adds context about the returned data but does not significantly enhance parameter semantics beyond what the schema already provides. 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 gets detailed metadata for a specific relational entity, listing concrete details like column definitions, data types, SQL type mappings, and ETL extraction capabilities. It distinguishes itself from siblings by emphasizing optimization for data warehouse loading and transformation workflows.
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 mentions it is 'optimized for data warehouse loading and transformation workflows,' which implies a use case but does not explicitly state when to use this tool versus alternatives like 'get_relational_metadata' or 'get_table_schema'. No exclusion or alternative guidance is provided.
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, and description does not disclose behavioral aspects like idempotency, side effects, or permissions. It only describes input syntax, not server behavior.
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 succinct sentences: first defines purpose, second adds essential syntax hints. No redundancy or filler.
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?
Does not describe return format, pagination behavior, or how results are structured. Given complex optional parameters and no output schema, more detail is needed for complete understanding.
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 parameters with descriptions (100% coverage). Description adds minimal extra value (e.g., SCOPE prefix usage), but semantics are mostly captured in schema. Baseline 3 applies.
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 universal search across all catalog items and lists specific item types (KPIs, assets, etc.). It distinguishes from sibling tools like search_tables by implying broader scope.
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 guidance on using SCOPE prefix and Boolean operators for targeted searches. Lacks explicit when-not-to-use or alternatives, but context is clear enough for an AI agent to decide.
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 the full burden. It indicates that the tool returns runtime data but does not disclose whether it is read-only, requires specific permissions, or has any rate limits. It is adequate but minimally transparent beyond stating the output.
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 main sentences plus a list of use cases. It front-loads the core purpose and avoids verbosity. The structure is clear and 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 6 parameters and no output schema, the description adequately covers the returned data types but lacks details on pagination behavior (beyond schema) and result structure. It is minimally complete for the complexity.
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 well. The description adds no additional meaning beyond the overall purpose. It does not explain parameter relationships or provide examples, meeting the baseline but not exceeding it.
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 with a specific verb ('List') and resource ('runtime/deployed objects'). It further elaborates on what is returned (deployment status, runtime metrics, execution history, performance statistics) and lists use cases. This distinguishes it from sibling tools like 'get_asset_details' which focus on non-runtime aspects.
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 provides explicit use cases for monitoring and analysis (monitoring deployed assets, tracking execution status, analyzing runtime performance). However, it does not mention when not to use this tool or suggest alternatives, which slightly reduces guidance.
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 must carry the burden. It states the tool lists and returns data, implying a read-only operation, but does not disclose any behavioral traits such as permission requirements, rate limits, or side effects. For a simple list tool, this is adequate but not fully transparent.
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-loaded with the main purpose, and each sentence adds value: first sentence states the action, second sentence elaborates on return details. No superfluous 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 lack of output schema, the description partially explains return values (names, types, URLs). It does not cover pagination or error conditions, but for a list tool with well-documented parameters, it is reasonably complete. Could be improved with usage guidance.
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%, with descriptions for space_id, asset_id, top, and skip. The description adds no additional meaning beyond the schema (e.g., 'within a specific asset' aligns with asset_id). 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 the tool lists analytical datasets within a specific asset, distinguishing it from siblings like list_catalog_assets or get_analytical_metadata. The verb 'list' and resource 'analytical datasets' are specific.
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 when you need to discover analytical models for an asset, but it does not explicitly state when to use this tool versus alternatives like list_catalog_assets or query_analytical_data. No when-not-to-use guidance 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?
With no annotations provided, the description fully discloses the tool returns variables (name, type, default, nullable, multi_value), filter annotations, and the column list. It implies a read-only operation and adds context beyond the name, though it could mention prerequisites like asset deployment status.
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 two sentences: first states core functionality, second adds usage guidance. It is relatively concise and well-structured, though the first sentence is slightly lengthy.
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 tool with 2 params, no output schema, and no annotations, the description provides a good overview of inputs and outputs. However, it lacks details on output structure (e.g., array of objects) and possible error conditions, leaving some gaps in 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 coverage is 100% with descriptions for both parameters. The description adds some context by explaining the asset type (view/analytic model), but does not significantly enhance the meaning beyond the schema. Baseline of 3 is appropriate given high 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?
The description clearly states the tool retrieves input parameters/variables and filter-capability annotations from OData $metadata of a SAP Datasphere asset. It specifies the verb 'Retrieve' and the resource, and distinguishes from siblings by mentioning it is for parameterised assets like views or analytic models.
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 says when to use this tool: when the asset is parameterised and variables need to be known before querying. It provides clear context for use but does not mention when not to use it or suggest alternatives among the many sibling tools.
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 the burden. It implies read-only behavior by describing retrieval of structure and metadata, but does not disclose authentication needs, rate limits, or error handling (e.g., object not found). Adds some value beyond schema but incomplete.
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 with zero waste. Front-loaded with purpose, followed by detailed examples of what is retrieved for each object type. Efficient and scannable.
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 4 parameters and no output schema. Description explains what it returns for different object types (tables, views, models, data flows). Missing are error cases, performance notes, or output format hints, but overall sufficient for typical use.
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. Description provides general context (e.g., example values) but does not add significant additional meaning beyond what the schema provides.
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 retrieves complete design-time object definitions from SAP Datasphere repository, listing specific object types (tables with columns/keys/indexes, views with SQL, analytical models with dimensions/measures, data flows with transformation steps). It distinguishes from siblings like get_table_schema or get_analytical_model by emphasizing 'complete' and broad coverage.
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?
Description explicitly states use cases: 'understanding object implementation details, extracting schema information, or planning migrations.' It provides clear context but does not mention when not to use or suggest alternatives, which would have made it stronger.
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 burden. It discloses the return includes schema information and SQL type mapping, but lacks details on side effects, authentication requirements, or rate limits. Adequate but not exhaustive.
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-loaded with the primary purpose, and each sentence adds value—no wasted words. Ideal conciseness.
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 3 parameters, no output schema, and presence of sibling tools, the description adequately covers purpose, included schema elements, and SQL type mapping. It lacks details on output structure or potential edge cases, but is mostly complete 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 coverage is 100%, and the description adds no additional meaning beyond the schema's parameter descriptions (e.g., 'Space identifier (e.g., 'SAP_CONTENT')'). With high coverage, 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 'Retrieve CSDL metadata for relational consumption of a specific asset,' specifying the verb (retrieve) and resource (CSDL metadata for a specific asset). It lists included elements (tables, columns, data types, keys, relationships) and distinguishes it from siblings like get_analytical_metadata or get_table_schema.
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 indicates usage for 'relational consumption' and 'relational data access and ETL planning,' providing context. However, it does not explicitly state when not to use or offer alternatives, though sibling tool names like get_analytical_metadata serve as implicit contrasts.
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 must carry the full burden. It implies read-only behavior by stating 'list' and 'returns', but does not explicitly confirm non-destructiveness or mention authentication needs, rate limits, or side effects. The disclosure is adequate but not thorough.
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, front-loaded with the core action and resource, then clarifying the return type. Every word serves a purpose 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 explains the return (OData entity sets) and connects to broader workflow (ETL operations). Without an output schema, it provides sufficient context for a list operation. Could be more complete by explicitly noting that it is the starting point for subsequent queries.
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%, providing clear descriptions for all three parameters. The description adds contextual purpose but no additional meaning beyond what the schema offers. 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 the verb 'List' and the resource 'relational entities (tables/views) within a specific SAP Datasphere asset'. It distinguishes from siblings by specifying the scope (all entities in an asset) and the purpose (row-level data access and ETL operations), which is distinct from tools like get_relational_entity_metadata or query_relational_entity.
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 discovery before querying detailed data, but does not explicitly state when not to use it or mention alternative tools. The context is clear but lacks exclusions or guidance on specific 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?
With no annotations provided, the description carries the burden of behavioral disclosure. It mentions large batch processing (up to 50,000 records), filtering, column selection, and pagination, but does not disclose side effects, permissions, rate limits, or error behavior. The read-only nature is implied but not stated explicitly.
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—four sentences that front-load the core purpose and key capabilities. Every sentence provides useful information: what it does, batch limit, feature set, usage context, and a prerequisite tip. There is no redundancy or fluff.
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 8 parameters and no output schema, the description competently covers the main usage context, capabilities, and a prerequisite step. It lacks explicit details about return value structure, but the absence of an output schema and the straightforward 'query' semantics mitigate this. The description is reasonably complete for a developer to start using the tool effectively.
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 input schema covers 100% of parameters with detailed descriptions, so the baseline is 3. The description adds no significant parameter-level detail beyond what the schema already provides; it only refers generally to filtering, column selection, and pagination, which are already documented 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 begins with a specific verb phrase 'Execute OData queries' and clearly identifies the resource as 'relational entities', immediately distinguishing this tool from analytical query tools. It further specifies the ETL context and explicitly references sibling tool list_relational_entities, making the purpose unmistakable.
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 gives clear context for when to use this tool (ETL data extraction, data warehouse loading, analytics pipelines) and instructs users to call list_relational_entities first. However, it does not explicitly state when not to use it or name alternative query tools, leaving some ambiguity versus query_analytical_data or execute_query.
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 description carries full burden. It mentions the API endpoint and return data fields, but does not explicitly state read-only nature or discuss side effects, auth needs, or rate limits. Adequate 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?
Well-structured with sections, bullet lists, and examples. Each section adds value, though the length is slightly above necessary. Front-loaded with 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?
No output schema, but the description comprehensively lists what metadata will be returned, covers params, examples, use cases, and API details. Lacks error conditions but adequate for the tool's complexity.
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 100% with descriptions. The description adds value with examples, format hints (UPPERCASE for space_id), and explanation of optional expand_fields, enhancing beyond 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 verb 'Get' and resource 'comprehensive metadata for a specific SAP Datasphere asset.' It distinguishes from siblings like get_space_assets (list) and get_analytical_model (specific model type).
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 'Use this tool when:' with examples, 'What you'll get', 'Use cases', and example queries. Does not state when NOT to use or name alternatives explicitly, but context is clear.
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 must carry the full burden. It lists what you get (user IDs, status, etc.) but does not explicitly state read-only nature, authentication requirements, or error handling. Some behavioral context is implied but not confirmed.
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 clear sections (overview, when to use, what you'll get, required parameter, examples). It is front-loaded with the purpose. Slightly verbose with access types and CLI note, but each section 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?
Given no output schema, the description explains the return fields (IDs, names, status, etc.). Input schema is fully covered. Missing details like pagination or error cases, but adequate for a list 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 100%, but the description adds value by specifying the format for space_id (uppercase) and providing examples. The optional output_file parameter is also explained. This goes beyond the 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?
Schema coverage is 100%, so baseline is 3. Description adds value by explaining the parameter's effect (include_details adds owner, dates, connection counts) and default behavior. Goes beyond schema to clarify practical 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?
Description explicitly states 'List all SAP Datasphere spaces with their status and metadata.' It specifies the resource (spaces), action (list), and output elements (status, metadata). It distinguishes from sibling tools like get_space_info by positioning it as a next step.
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 clear 'Use this tool when:' section with specific scenarios (e.g., user asks about spaces, starting exploration, checking status). Also includes 'Next steps' suggesting get_space_info for further details. However, does not explicitly state when not to use or compare with other list tools.
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?
No annotations provided, so description fully discloses impacts: old password invalidated immediately, new password auto-generated, user must change on next login, sessions terminated, action logged. This exceeds typical 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?
Well-structured with sections, front-loaded key sentence, and appropriate detail for a high-risk tool. While slightly verbose with examples and best practices, every section adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

The input schema has 100% description coverage, but the description adds significant value: it explains the user_definition structure in detail, provides example JSON, clarifies that database_user_id will be prefixed with space name, and recommends the optional output_file for security. This goes well 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 'Create a new database user' and specifies the scope (in a SAP Datasphere space with permissions). It distinguishes from sibling tools like delete_database_user, reset_database_user_password, and update_database_user by focusing on creation. The provided example queries further clarify the purpose.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description explicitly lists when to use the tool (e.g., user requests create, setting up user access) and provides example queries. It does not explicitly state when not to use, but the contextual examples implicitly guide against misuse. The high-risk warning also sets expectations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
