  2.9/5.0
  Behavior2/5

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

  With no annotations provided, the description carries full burden for behavioral disclosure but provides minimal information. It states what the tool does but doesn't disclose important behavioral traits like whether this is a read-only or write operation, what permissions are required, whether there are query size or complexity limits, what happens with malformed queries, or what the response format will be. The description adds almost no behavioral context beyond the basic action.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is extremely concise - a single sentence that directly states the tool's purpose without any wasted words. It's front-loaded with the essential information and appropriately sized for what it communicates.

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

  Completeness2/5

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

  Given that this is a SQL execution tool with no annotations and no output schema, the description is insufficiently complete. It doesn't explain what kind of SQL queries are supported, what database/schema context is used, whether transactions are supported, what the return format will be, or any error handling behavior. For a tool that could potentially execute destructive operations, this level of documentation is inadequate.

  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 has 100% description coverage with the 'query' parameter clearly documented. The description doesn't add any meaningful parameter semantics beyond what the schema already provides - it doesn't specify query syntax requirements, supported SQL dialects, parameter binding methods, or any constraints on the query content. With complete schema coverage, 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.

  Purpose4/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the action ('Execute') and target resource ('a SQL query in the Adb MySQL Cluster'), providing specific verb+resource pairing. However, it doesn't explicitly differentiate from sibling tools like get_execution_plan or get_query_plan, which appear to be related query analysis tools rather than execution tools.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools, suggest appropriate query types, warn about limitations, or provide any context about when this execution tool should be preferred over the analysis-focused sibling tools.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• get_execution_planC
  2.9/5.0
  Behavior2/5

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

  With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool retrieves 'actual execution plan with runtime statistics', which implies a read-only, non-destructive operation, but doesn't clarify performance impact, permissions needed, or what 'runtime statistics' include (e.g., execution time, row counts). This leaves significant gaps for a tool that likely interacts with a database system.

  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, efficient sentence that front-loads the core purpose without unnecessary words. Every part of the sentence contributes directly to understanding the tool's function, making it highly concise and well-structured.

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

  Completeness2/5

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

  Given the complexity of SQL execution plans and the lack of annotations or output schema, the description is incomplete. It doesn't explain what an 'execution plan' entails, how runtime statistics are presented, or potential limitations (e.g., only for certain databases). For a tool with no structured output documentation, this leaves the agent with insufficient context for effective 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?

  The schema description coverage is 100%, with the single parameter 'query' fully documented in the schema as 'The SQL query to analyze'. The description adds no additional semantic context beyond this, such as query format requirements or supported SQL dialects, so it meets the baseline for high schema coverage.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose4/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the action ('Get') and resource ('execution plan with runtime statistics for a SQL query'), making the purpose immediately understandable. It distinguishes from 'execute_sql' (which runs queries) and 'get_query_plan' (which likely provides theoretical plans without runtime data), though the distinction from the latter could be more explicit.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description provides no guidance on when to use this tool versus alternatives like 'execute_sql' or 'get_query_plan'. It doesn't mention prerequisites, such as needing a valid SQL query or when runtime statistics are available, leaving the agent 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.

• get_query_planC
  2.9/5.0
  Behavior2/5

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

  With no annotations provided, the description carries the full burden but only states what the tool does without behavioral details. It doesn't disclose if this is a read-only operation, has side effects, requires specific permissions, or involves rate limits, which are critical for a tool analyzing SQL queries.

  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, direct sentence with zero wasted words, making it highly concise and front-loaded. It efficiently communicates the core function without unnecessary elaboration.

  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 no annotations, no output schema, and a tool that likely returns complex query plan data, the description is insufficient. It doesn't explain the return format, potential errors, or usage context, leaving gaps in understanding for effective tool invocation.

  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 has 100% description coverage, clearly documenting the 'query' parameter. The description adds no additional meaning beyond this, such as SQL dialect support or query complexity limits, so it meets the baseline for high schema coverage without extra value.

  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 action ('Get') and target ('query plan for a SQL query'), making the purpose immediately understandable. It doesn't explicitly differentiate from sibling tools like 'get_execution_plan', which might be similar, so it misses the highest score for sibling distinction.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description provides no guidance on when to use this tool versus alternatives like 'execute_sql' or 'get_execution_plan'. It lacks context such as whether this is for debugging, optimization, or pre-execution analysis, leaving the agent with no usage criteria.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
