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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether the tool creates, fetches, updates, or returns something, nor does it mention side effects, output, or side effects like persisting data or calling external systems.

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: neither sentence earns its place. The first sentence only labels the tool and the second only points to a URL. This is under-specification rather than efficient communication.

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?

There is no output schema and no annotations, so the description should explain what the tool produces or how it behaves; it does neither. The zero-parameter schema reduces the input burden, but the agent is still left without a behavioral contract or return-value expectation.

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 named parameters and no required parameters, so there is little parameter semantics for the description to clarify. The baseline for zero-parameter tools is 4; the schema coverage is effectively 100% and the description is not required to document parameters that do not exist, though additionalProperties:true leaves the input contract somewhat open.

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 build_diligence_checklist') and adds a URL, without stating what the tool does, what a diligence checklist is, or what outcome to expect. It is effectively a tautology that names the resource but does not define the action or result.

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, what conditions favor it, or which sibling tools might be alternatives. The long sibling list is not referenced at all, leaving the agent to guess when build_diligence_checklist is appropriate.

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