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 neither effects, side effects, return behavior, nor any operational constraints. The only extra claim—that the tool shares a name with a live catalog—does not describe the tool's runtime 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 text is short, but that is under-specification rather than conciseness. Neither sentence earns its place: the first repeats the tool name, and the second points to a URL without conveying functional content.

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?

Despite having no required parameters or output schema, the definition is still profoundly incomplete for an opaque tool name like run_sector_overview. An agent cannot determine what inputs are expected, what the tool returns, or what action it performs; the URL hint is insufficient.

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 schema declares zero named parameters and the context confirms a parameter count of 0, so there are no parameter semantics for the description to add. The baseline for zero-parameter tools applies; the description's silence on parameters is not a meaningful gap, though additionalProperties: true is left unexplained.

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 is a tautology: 'MCP-Agents tool run_sector_overview' restates the tool name and adds no verb, resource, or outcome. Mentioning that it has the same name as a live catalog URL does not explain what the tool does, and it is impossible to distinguish from sibling run_* tools based on this text.

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, when not to use it, or how it compares to alternatives such as run_competitive_landscape, run_credit_screen, or run_risk_discovery. The description provides no decision-relevant context.

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