execute_query

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

No annotations are provided, so the description must disclose behavioral traits. It mentions that the tool can execute INSERT/UPDATE/DELETE, implying data modification, but lacks details on side effects, authentication needs, rate limits, transaction behavior, or error handling. The description does not go beyond the obvious.

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 sentence that front-loads the purpose and lists supported SQL commands. It is concise and contains no unnecessary words.

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?

The tool has one simple parameter and no output schema. The description mentions it returns results but not in what format (e.g., rows, affected rows). For a query execution tool, more details on return structure, error behavior, and supported SQL dialect would improve completeness, but it covers the essential purpose.

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% (the schema describes the query parameter). The description adds that the query can be SELECT, INSERT, UPDATE, or DELETE, which is useful context but does not significantly deepen parameter understanding beyond the schema.

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 it executes a SQL query on SQL Server and specifies it is for SELECT, INSERT, UPDATE, and DELETE. It differentiates itself from sibling tools that focus on metadata (describing tables, listing databases) by explicitly mentioning execution of DML and DQL statements.

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 indicates when to use the tool (for SQL queries of types SELECT, INSERT, UPDATE, DELETE). It provides clear context, though it does not explicitly exclude scenarios or mention alternatives. However, the sibling tools are distinctly different, so implicit differentiation exists.

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