Listar canais de tickets

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

No annotations are provided, so the description carries the full behavioral burden. It implies a read-only enumeration but says nothing about return shape, ordering, pagination, or whether the channel list is stable/global — all of which matter for a lookup an agent may cache or re-call.

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 front-loaded sentence with no preamble. It is slightly redundant, restating tickets twice ('para tickets (chamados)' and 'no sistema de tickets'), which trims a point but does not obscure the intent.

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, argument-free reference list the description is minimally sufficient, and no output schema exists so return values need not be explained. Still, it does not say what a 'canal de entrada' contains or how the result is structured, leaving a small gap for an agent deciding how to use the output.

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 takes zero parameters, so the baseline is 4. There is no parameter meaning the description could have added or omitted.

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 and resource ('Lista os canais de entrada cadastrados para tickets'), so the agent knows this returns the catalog of intake channels. It does not differentiate from structurally similar siblings like listar_prioridades_tickets or listar_areas_tickets, but the resource noun is unambiguous enough.

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?

There is no guidance on when to call this versus the other listar_* lookup tools, nor any stated prerequisite. For a no-argument reference lookup, usage is somewhat self-evident, but the description provides nothing explicit.

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