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

The readOnlyHint annotation already tells the agent this is a safe, non-mutating call, so the bar is lower. The description adds the underlying API endpoint (GET /ticket_results) and clarifies the semantic meaning of the returned entities, but says nothing about pagination behavior or result volume.

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?

Two compact sentences with zero filler; the resource definition and clarifying examples are front-loaded before the endpoint citation.

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 trivial single-parameter read tool with no output schema, the description covers purpose, semantics of the returned items, and a concrete use context. Only minor gaps remain, such as pagination expectations for a list endpoint.

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% and the single 'page' parameter is fully documented in the schema, so the description correctly does not duplicate it. Baseline 3 applies since the description adds no parameter-level meaning beyond what the schema provides.

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?

States a specific verb (List) and resource (ticket results), then clarifies what that resource actually is with concrete examples ('Resolved', 'Sale'). This distinguishes it from siblings like trengo_list_tickets and trengo_list_labels without requiring the schema to be opened.

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 phrase 'that can be applied when closing a ticket' implies the tool is a prerequisite lookup for trengo_close_ticket, which is useful contextual routing. However, it never explicitly states when to call it versus alternatives, nor any exclusions or prerequisites.

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