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

With no annotations, the description carries the full burden of disclosing behavior. It only repeats the name and references a live catalog; it discloses nothing about side effects, permissions, reversibility, input/output behavior, or rate limits. An agent has zero behavioral information beyond the name itself.

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 it is under-specified rather than concisely informative. The single sentence merely restates the tool name and gives a URL, so it fails to earn its place by conveying any functional substance.

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 no annotations, no output schema, and no parameter definitions, the description must explain the operation, return value, and prerequisites. It does none of this, leaving the agent with only a name and an external link that offer no actionable calling information.

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 defines zero parameters and context reports 0 params, so the baseline is 4 and the description need not elaborate. Though additionalProperties: true technically allows arbitrary inputs, the description adds no parameter meaning, but with no declared parameters there is nothing to document.

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 essentially a restatement of the tool name ('MCP-Agents tool link_to_firm') plus an external URL. It states no verb, resource, or outcome, so an agent cannot tell what action 'link_to_firm' performs or how it differs from any of the firm-related sibling 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?

There is no guidance on when to use this tool versus alternatives. No context, no exclusion criteria, and no mention of related tools such as create_deal_workspace or fetch_company_intelligence. The absence of any usage direction leaves the agent to guess.

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