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

With no annotations present, the description carries the full burden of behavioral disclosure. It reveals nothing about side effects, inputs, outputs, or operation semantics—'same name as the live catalog' is metadata, not 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 wastes its only sentence on a name repetition and a URL reference. This is under-specification rather than effective conciseness, and no useful information is front-loaded.

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 tool with a compound financial-domain name, no annotations, no output schema, and no behavioral description, the definition is woefully incomplete. An agent cannot determine correct invocation, expected inputs, or output shape.

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 has zero parameters and the description adds no parameter documentation, which is acceptable for a zero-parameter tool. However, the schema's additionalProperties:true is not clarified, so an agent still cannot know whether arbitrary arguments are expected or accepted.

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 only restates the tool name ('MCP-Agents tool run_financial_statement_spread') and says it shares a name with a live catalog. There is no verb, resource, or functional statement, making it a tautology that fails to distinguish it from dozens of sibling run_* tools.

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 about when to use this tool versus alternatives such as run_statement_qa or run_credit_screen. There is no context, no condition, and no mention of exclusions or prerequisites.

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