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

No annotations provided, so the description carries full burden. It discloses 'newest first' ordering, which is one useful behavioral detail, but says nothing about read-only semantics, pagination, response shape, or failure modes.

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 sentence that is front-loaded and conveys purpose and ordering in eight words. No wasted content.

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?

Adequate for a simple list-style tool with one optional parameter. The main gap is the undocumented `limit` parameter and no note about the fields returned per agent, but overall it's a low-complexity tool that doesn't demand much beyond a minimal definition.

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?

Schema description coverage is 0% and the description never mentions the `limit` parameter at all — no semantics, bounds, or default behavior. The description fails to compensate for the undocumented schema.

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 identifies a specific verb ('List') and a distinct resource ('registered agents on this Help Desk') with an ordering constraint ('newest first'). The resource clearly differs from sibling tools like get_ticket and get_tasks, though it doesn't explicitly contrast against them.

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 on when to use this tool versus the many siblings (get_arrivals, get_desk, get_tasks, etc.). The name and description make the purpose inferable, but there are no explicit exclusions or conditions directing the agent to choose this tool over alternatives.

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