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

Annotations already indicate destructive and non-idempotent behavior, but the description adds no side-effect context (e.g., overwriting existing connection settings). It also includes irrelevant behavioral instructions ('Powered by CorpusIQ', data accuracy contract) that do not pertain to the tool's operation, adding noise without transparency.

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 core purpose is a single sentence, but the description appends a long data-accuracy contract and a response-format instruction unrelated to configuring a connection. This bloats the description and buries the essential meaning, violating conciseness and structure principles.

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 (9 params, destructive annotation, no output schema), the description is incomplete. It does not mention return values, connection verification, post-configuration steps, or the impact of the operation, 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.

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

With 0% schema description coverage, the description completely omits any explanation of the 9 parameters (host, port, user, password, database, driver, encrypt, timeout, trust_server_certificate). The agent is forced to rely solely on parameter names and defaults, which is insufficient for correct invocation.

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 'Configure MSSQL connection for the current user' with a specific verb and resource, distinguishing it from query/describe/list tools for MSSQL. However, it doesn't elaborate on what configuration entails or explicitly differentiate from similar configure tools (e.g., configure_cosmos_connection) beyond the database name.

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?

There is no guidance on when to use this tool, prerequisites, or alternatives. It does not mention that it may be required before querying MSSQL or that it overwrites existing settings, leaving the agent to infer usage from the name alone.

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