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

Annotations already declare idempotentHint=true and destructiveHint=true, but the description adds the actual effect of each mode -- silencing automated messages versus restoring the account-level default -- which is real behavioral context beyond the structured fields. It stops short of saying whether the change takes effect immediately for in-flight conversations or what permissions are required.

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 front-loaded sentence that maps each of the three modes to its effect with no filler. The conversational phrasing is compact, though the clipped grammar makes the 'default' clause slightly less crisp than the other two.

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?

With only two parameters, no output schema, and annotations covering the safety profile, the description is adequate: both modes and the reference parameter are accounted for. It leaves open what the account default resolves to and whether silencing affects queued or automated replies, which matters for a destructive-flagged tool.

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 50%: conversation_ref already carries a description pointing to list_conversations, while mode is a bare enum in the schema. The description explains all three mode values, compensating for that gap, but adds no clarification for conversation_ref and no format or scope details.

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 a specific verb and resource -- turning the message bot on, off, or back to the account setting, scoped to one conversation -- and enumerates the three modes. It does not explicitly distinguish itself from nearby siblings such as set_post_comment_bot or update_comment_bot, which handle different bot surfaces.

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 'por ejemplo para atender a mano' gives one concrete situation for switching off, which implies when the tool is useful. There is no explicit when-not guidance, no prerequisites, and no naming of alternative tools for related bot configuration.

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