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

With no annotations provided, the description carries full burden for behavioral disclosure. It states this is a creation operation but doesn't mention important behavioral aspects: whether this requires specific database permissions, if it's a destructive operation that might overwrite existing tables, what happens on success/failure, or any rate limits. The description is minimal and doesn't compensate for the lack of annotations.

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

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

The description is a single, efficient sentence that front-loads the core purpose ('Create a new table in the database') and adds necessary qualification ('with specified columns and constraints'). Every word serves a purpose with zero waste or redundancy. It's appropriately sized for a creation operation with moderate complexity.

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

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

For a database mutation tool with no annotations, no output schema, and moderate parameter complexity (3 parameters including nested objects), the description is insufficient. It doesn't address critical context: what permissions are needed, whether the operation is idempotent, what happens if a table already exists, what the return value looks like, or error conditions. The agent lacks necessary operational context for safe and effective use.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description mentions 'columns and constraints' which aligns with the 'columns' and 'table_options' parameters in the schema, providing some semantic context beyond the schema's technical descriptions. However, with 67% schema description coverage (2 of 3 parameters have descriptions), the description doesn't fully compensate for the coverage gap - it doesn't explain what 'table_options' encompasses or provide examples of constraint types. The baseline is appropriate given partial schema coverage.

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

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

The description clearly states the action ('Create a new table') and the resource ('in the database'), with additional context about what gets created ('with specified columns and constraints'). It distinguishes from siblings like 'list_tables' or 'describe_table' by being a creation operation rather than querying existing tables. However, it doesn't explicitly differentiate from other potential table-related operations that might exist in other contexts.

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

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

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., database permissions, existing schema), when not to use it (e.g., for temporary tables vs permanent), or refer to sibling tools like 'generate_er_diagram' for design planning or 'optimize_sql' for performance considerations. The agent must infer usage from the tool name alone.

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

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action ('Get detailed information') but doesn't describe what 'detailed information' includes (e.g., schema, columns, constraints), whether it requires specific permissions, or how errors are handled. For a tool with no annotations, this leaves significant gaps in understanding its behavior.

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

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

The description is a single, efficient sentence with zero waste. It's front-loaded with the core purpose ('Get detailed information about a table'), making it easy to parse quickly. Every word earns its place, and there's no unnecessary elaboration.

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

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

Given no annotations and no output schema, the description is incomplete for a tool that likely returns complex metadata. It doesn't explain what 'detailed information' entails (e.g., column types, indexes), leaving the agent uncertain about the return value. For a tool with such contextual gaps, more detail is needed to be fully helpful.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage, with the 'table' parameter clearly documented as 'Name of the table to describe'. The description doesn't add any meaning beyond this, such as format examples or constraints. With high schema coverage, the baseline score of 3 is appropriate, as the schema does the heavy lifting.

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

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

The description clearly states the verb ('Get') and resource ('detailed information about a table'), making the purpose immediately understandable. It distinguishes from siblings like 'list_tables' (which lists tables) and 'query_table' (which queries data), though it doesn't explicitly differentiate them. The description is specific but lacks explicit sibling differentiation for a perfect score.

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

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

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention when to use 'describe_table' instead of 'list_tables' (for metadata vs. listing) or 'query_table' (for data vs. structure), nor does it specify prerequisites like needing an existing table. Usage is implied from the name but not explicitly stated.

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

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action but does not reveal any behavioral traits such as whether it requires database permissions, if it's read-only or mutative, potential rate limits, or what the output format entails beyond 'Mermaid ER diagram'. This leaves significant gaps for an agent to understand how to invoke it safely and effectively.

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

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

The description is a single, efficient sentence that directly states the tool's function with zero waste. It is front-loaded and appropriately sized for a tool with no parameters, making it easy for an agent to parse and understand quickly.

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

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

Given the tool has no parameters, no annotations, and no output schema, the description is minimally adequate by stating what it does. However, it lacks details on output format (e.g., Mermaid syntax specifics), behavioral context, or usage compared to siblings, which are important for a tool that generates diagrams. This makes it complete enough for basic understanding but with clear gaps in practical guidance.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters, and the schema description coverage is 100%, so there is no need for parameter details in the description. The baseline for such cases is 4, as the description appropriately focuses on the tool's purpose without redundant parameter information, though it could slightly improve by noting the lack of parameters explicitly.

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

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

The description clearly states the verb 'Generate' and the resource 'Mermaid ER diagram of the database schema', making the purpose specific and actionable. However, it does not explicitly differentiate from sibling tools like 'describe_table' or 'list_tables', which might also provide schema information, so it falls short of a perfect score.

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

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

The description provides no guidance on when to use this tool versus alternatives such as 'describe_table' for detailed table info or 'list_tables' for a simple overview. It lacks explicit context, prerequisites, or exclusions, leaving the agent to infer usage based on the tool name alone.

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

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions 'insert' implying a write operation, but lacks details on permissions needed, whether data overwrites existing rows, transaction behavior, or error handling. This is inadequate for a mutation tool with zero annotation coverage.

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

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

The description is a single, efficient sentence that front-loads the core action. It wastes no words, though it could be slightly more informative given the tool's complexity.

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

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

For a mutation tool with no annotations and no output schema, the description is incomplete. It doesn't explain what happens after insertion (e.g., success confirmation, row count returned), error conditions, or dependencies on existing table structure, leaving significant gaps for agent understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema fully documents all parameters. The description adds no additional meaning beyond implying data generation and insertion, which is already clear from the tool name. Baseline 3 is appropriate when the schema does all the work.

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

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

The description clearly states the action ('Generate and insert synthetic data') and the target resource ('into an existing table'), which distinguishes it from siblings like create_table or query_table. However, it doesn't explicitly differentiate from all siblings (e.g., run_read_query might also involve data manipulation).

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

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

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., table must exist), when not to use it (e.g., for production data), or refer to sibling tools like create_table for table creation first.

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

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

There are no annotations, so the description must fully disclose behavior. It merely states 'List all tables', which implies a read operation, but omits details on permissions, output format, or performance implications.

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

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

The description is a single, efficient sentence with no unnecessary words. It is appropriately front-loaded but lacks any structural enhancement like bullet points that could aid readability.

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

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

Given no output schema or annotations, the description should explain what 'list' returns (e.g., table names, schemas). Without this, an agent may not know how to use the result. Sibling tools like 'describe_table' suggest additional context might be needed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has no parameters, so the description cannot add parameter meaning. Baseline for zero parameters is 4, and the description is sufficient for the parameterless case.

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

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

The description clearly states the tool lists all tables in the database. While it distinguishes from 'describe_table' by listing instead of describing, it does not explicitly differentiate from potential siblings like 'query' or 'execute'.

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

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

The description provides no guidance on when to use this tool versus its siblings (describe_table, execute, query). It is implied that it retrieves table names, but no context on prerequisites or alternatives.

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

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the tool uses 'PROFILE' (implying a profiling mechanism) and provides recommendations, but doesn't specify whether this is a read-only analysis, if it requires specific permissions, what the output format looks like, or any rate limits. For a tool with zero annotation coverage, this leaves significant behavioral gaps.

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

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

The description is a single, efficient sentence that front-loads the core functionality ('analyze a SQL query') and adds key details ('using PROFILE and provide optimization recommendations') without any wasted words. Every part of the sentence contributes directly to understanding the tool's purpose.

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

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

Given the tool's moderate complexity (analysis with optimization recommendations), no annotations, no output schema, and a single well-documented parameter, the description is adequate but incomplete. It covers the basic purpose but lacks details on behavioral traits, output format, and usage context relative to siblings, which are needed for a more complete understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with the single parameter 'query' well-documented in the schema ('SQL query to analyze and optimize'). The description adds minimal value beyond this, only reiterating that it analyzes and optimizes the query. Since the schema does the heavy lifting, 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.

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 specific verbs ('analyze' and 'provide optimization recommendations') and identifies the resource ('SQL query'). It distinguishes from siblings like 'query_table' or 'run_read_query' by focusing on analysis rather than execution. However, it doesn't explicitly differentiate from all siblings (e.g., 'describe_table' might also analyze queries).

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

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

The description implies usage context ('analyze a SQL query... and provide optimization recommendations'), suggesting it's for performance tuning rather than data retrieval or schema operations. However, it lacks explicit guidance on when to use this tool versus alternatives like 'run_read_query' for execution or 'describe_table' for schema analysis, and doesn't mention prerequisites or exclusions.

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

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

With no annotations, the description carries full burden but only states the action without disclosing behavioral traits such as whether it's read-only or destructive, permission requirements, rate limits, or response format. It lacks critical context for safe and effective use.

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

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

The description is a single, efficient sentence with zero waste, appropriately sized and front-loaded. It directly states the tool's function without unnecessary elaboration, earning full marks for conciseness.

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

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

Given the tool's complexity (executing queries, potentially with side effects), no annotations, no output schema, and incomplete behavioral disclosure, the description is inadequate. It fails to provide enough context for the agent to understand risks, results, or proper application.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents the 'query' parameter as 'SQL query to execute'. The description adds no additional meaning beyond this, such as query syntax examples or constraints, 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.

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

The description 'Execute a query on a table' states a general purpose (verb+resource) but is vague about what type of query (read/write, SQL specifics) and doesn't distinguish from sibling 'run_read_query' or 'optimize_sql'. It minimally meets the requirement but lacks specificity for differentiation.

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

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

No guidance is provided on when to use this tool versus alternatives like 'run_read_query' or 'optimize_sql'. The description implies a general query execution but doesn't specify context, exclusions, or prerequisites, leaving the agent with no usage direction.

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

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states 'read-only (SELECT)' which implies non-destructive and safe operations, but fails to address critical aspects like permissions needed, rate limits, error handling, or what the output looks like (e.g., result format, pagination). This leaves significant gaps for an agent to understand the tool's behavior.

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

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

The description is a single, efficient sentence that front-loads key information ('Execute a read-only (SELECT) query'). There is no wasted verbiage or redundancy, making it highly concise and well-structured for quick comprehension.

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

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

For a database query tool with no annotations and no output schema, the description is incomplete. It lacks details on behavioral traits (e.g., security, performance), output format, and usage guidelines compared to siblings. While concise, it does not provide enough context for an agent to reliably use the tool without additional assumptions or trial-and-error.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage, with the 'query' parameter clearly documented as 'SQL SELECT query to execute'. The description adds no additional semantic details beyond this, such as syntax examples, supported SQL features, or constraints. Given the high schema coverage, a baseline score of 3 is appropriate as the schema does the heavy lifting.

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

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

The description clearly states the action ('Execute') and resource ('read-only (SELECT) query on the database'), making the purpose immediately understandable. It distinguishes from siblings like 'create_table' or 'optimize_sql' by specifying read-only SELECT operations, though it doesn't explicitly contrast with 'query_table' which might have overlapping functionality.

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

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

The description implies usage for executing SELECT queries, but provides no explicit guidance on when to use this tool versus alternatives like 'query_table' or 'optimize_sql'. It mentions 'read-only' which suggests safety, but lacks details on prerequisites, limitations, or specific 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.
