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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds nothing beyond that — no return shape, no pagination or result-size behavior, no indication of what a 'group' object contains.

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 short sentence with no filler and the resource front-loaded. It is efficient, though the extreme terseness is part of why key context is missing rather than being a virtue of tight writing.

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 no output schema and an undefined domain concept ('grupo de reuniones'), the description leaves the agent without enough to call this correctly against a dense sibling set. It neither defines the entity nor distinguishes the tool from adjacent list/type endpoints.

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% and both parameters are documented in the schema itself, including the flexible workspace_id ('UUID o nombre') and the meeting_type_id filter. The description only implies workspace scoping and never mentions the type filter, so it adds no meaning beyond the schema — baseline 3.

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 clear verb ('Lista') and resource ('grupos de reuniones') scoped to the workspace, so the basic action is understandable. However, it gives no differentiation from close siblings like get_meetings, get_meeting, or get_meeting_types, and never explains what a 'grupo de reuniones' actually is versus a meeting type.

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 when-to-use guidance, no prerequisites, and no mention of any alternative. An agent cannot tell from the text whether this is the right call versus get_meetings or get_meeting_types for a given request.

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