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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds the important visibility scope (internal vs requester-visible), but does not disclose pagination behavior, ordering, or return format. No contradiction with 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?

A single sentence front-loads the operation and includes the key qualifier about internal visibility. Every word earns its place; there is no filler or repetition.

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 listing tool with good safety annotations, the description is adequate, but there is no output schema and no parameter documentation. The description does not mention return shape, pagination usage, or default limits, leaving meaningful gaps that the agent must infer.

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 description coverage is 0%, and the description does not explain ticket_number, limit, or offset beyond implying the ticket context. Parameter names like ticket_number and limit/offset are somewhat self-explanatory, but the description adds no semantics and fails to compensate for the missing schema descriptions, especially for pagination behavior.

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 'Lista as comunicações internas de um chamado' — a specific verb (List) + resource (internal communications) + scope (of a ticket). It also clarifies the visibility boundary ('notas visíveis só para a equipe, nunca para o solicitante'), which distinguishes it from sibling tools like tiflux_list_ticket_answers.

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 parenthetical provides clear context: these are team-only notes, never visible to the requester, so an agent knows when to use this tool to fetch internal notes. However, it does not explicitly name alternatives or state when not to use this tool, so it falls short of full exclusion guidance.

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