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

No annotations are present, so the description carries the burden of behavioral disclosure. It does well by revealing the default filter behavior (unresolved only), the fact that status filters results, and the fields returned. It omits pagination details, but for a simple read-only list tool these are the key behaviors.

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?

One compact sentence delivers the action, scope, returned fields, filter behavior, and default. There is no filler or redundancy, and every clause earns its place.

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 a single optional parameter, no output schema, and a simple listing operation, the description is complete enough for correct invocation. It explains what will be returned and the default filter behavior, covering the main information an agent needs.

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 coverage is 100% for the single status parameter, listing all accepted values. The description adds meaningful semantics beyond the schema by stating that status filters results and that the default is unresolved only, which is not encoded in the 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 states a specific verb ('List'), a clear resource ('this account's support tickets'), and enumerates the returned fields (reference, subject, status, last activity). This clearly distinguishes it from sibling tools like get_ticket (single ticket) and create_ticket/reply_ticket (mutations).

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?

The description gives clear usage context: use this tool to list the current account's support tickets, with an explicit default of unresolved only. It does not name alternatives or state when not to use it, but the listing scope is unambiguous.

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