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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds useful domain context about what the results represent, but says nothing about pagination behavior or the shape of the returned list, so it adds only modest value beyond the annotations.

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 tight sentences: definition of the resource first, endpoint reference last. No filler, nothing redundant, and the most important information (what ticket results are) is front-loaded.

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 read-only list endpoint with a one-parameter schema and no output schema, the description supplies enough to call it correctly and understand the values returned. Minor gap: no hint about pagination limits or result volume, and no pointer to the close-ticket tool that consumes these values.

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?

Only one optional parameter (page) with 100% schema description coverage, so the schema already documents 1-based paging and that it can be omitted. The description adds no paging or format nuance, which is the correct baseline when the schema does the work.

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), and then defines the resource in domain terms ('closing outcomes, e.g. Resolved, Sale') so an agent understands what these are without opening anything else. This clearly distinguishes it from generic list siblings like trengo_list_labels or trengo_list_teams.

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 usage context (paired with the close-ticket flow), but there is no explicit when-to-use, when-not, or named alternative. An agent can infer the scenario but gets no routing guidance.

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