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

Annotations already declare this is a safe, read-only, non-destructive operation, so the description only needs to add scope. It adds that only tickets opened by the trainer with the Trainer Connect team are returned and that status is included, but it does not describe ordering, pagination, or whether closed tickets are included.

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 a single, front-loaded sentence that states the resource, ownership scope, and included field without any waste. Every clause adds useful information.

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 simple, zero-parameter, read-only list tool whose safety profile is already covered by annotations, the description is nearly complete. It tells the agent what tickets are returned and that status is included, though it could mention ordering or whether all statuses are shown.

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 parameters, so there are no parameter semantics to explain and the baseline is 4. The description does not need to compensate for schema gaps because the schema is empty and fully described.

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 names a specific resource (support tickets) and scope (opened by the trainer with the Trainer Connect team, with status), so the agent can tell it is a listing tool. It does not explicitly contrast itself with get_support_ticket or the open/reply siblings, which keeps it from a 5.

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?

Usage is implied by the title and the resource scope, but there is no explicit instruction on when to use this versus get_support_ticket for a single ticket or open_support_ticket to create one. The agent can infer the use case, but no alternatives or exclusions are stated.

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