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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false, so the safety profile is covered. The description adds valuable context beyond that: the chronological ordering and the shared-board semantics that explain why comments exist. It does not mention pagination or result shape, so not a 5.

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?

Ordering is front-loaded in the first sentence, with the second paragraph supplying context. The explanatory paragraph is slightly verbose relative to its value but not wasteful.

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?

There is no output schema, but the description supplies the key return-value characteristic (oldest-to-newest ordering) and the domain meaning of comments, while annotations cover the safety profile and the schema covers all params. Missing only minor details like the flat list shape or pagination behavior.

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 100%, so limit, task_id and workspace_id are fully documented in the schema itself. The description adds no parameter-level detail (e.g. default ordering interaction with limit), so baseline 3 is appropriate.

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 the specific resource ('El hilo de comentarios de una tarea') and its ordering ('del más viejo al más nuevo'), so the agent knows exactly what it retrieves. It does not explicitly differentiate from close siblings like get_task_detail or add_task_comment, keeping it below a 5.

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?

Explains the meaning and context of comments (conversation on shared boards, owner–guest dialogue without sharing the workspace), which implies when they matter. However there is no explicit 'use this when… / use X instead' routing, so guidance is only implied.

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