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

With no annotations, the description carries the full burden. It does disclose the key behavioral fact for a zero-parameter tool: it returns the complete client set with no filtering, plus that ids are included. It says nothing about ordering, volume, pagination, or permissions, and implies no read-only guarantee even though the name suggests it.

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?

A single ten-word sentence with zero filler; the complete-enumeration scope is front-loaded. Nothing is padded or repeated.

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 zero-parameter, no-output-schema list tool, the description is close to sufficient, but "with their ids" is the only hint about the return shape. Naming the other fields returned would have closed the remaining gap given there is no output schema.

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 takes no parameters, so the baseline is 4. There is no input whose meaning needs explaining, and the description correctly signals there are no filtering options by saying "Every client."

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?

"Every client of the firm, with their ids" identifies the resource (clients) and the scope (all of them, complete enumeration), which implicitly separates it from get_client, a single-record lookup. It lacks an explicit verb, but the intent is unambiguous.

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 statement of when to use this versus get_client, list_client_requests, or add_client. The agent must infer from the name that this is the bulk enumeration path and that get_client handles single lookups.

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