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

With no annotations provided, the description must disclose behavior, but it says nothing about execution, inputs, outputs, side effects, or remote behavior. The live-catalog reference offers no operational detail, so the agent is fully in the dark about what invoking this tool entails.

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 short, but brevity is not the same as conciseness. The first sentence is redundant with the tool name)Skip, and the second sentence about the live catalog does not help an agent use the tool. It is under-specified rather than economically specified.

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?

Even with zero parameters illustration, a tool with this name, no annotations, no output schema, and a large sibling set needs at least a one-sentence functional summary. This description provides none, so the agent cannot safely select or invoke the tool.

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 zero declared parameters, so the schema is already unambiguous about inputs. The description adds no parameter detail, but with no required parameters and no schema-defined properties, this is not a meaningful gap; arbitrary additionalProperties are allowed but unconstrained.

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 'MCP-Agents tool run_comps_analysis' is a tautology that merely restates the tool name without specifying what the tool does. The only additional detail, 'Same name as the live catalog...', provides provenance but no functional meaning, leaving an agent unable to determine the tool's purpose.

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 versus siblings like run_quantitative_analysis, run_competitive_landscape, or run_credit_screen. An agent cannot tell which scenario calls for comps analysis or what distinguishes it from the many other run_* tools.

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