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

Annotations already declare readOnly, idempotent, non-destructive and openWorld. The description adds value beyond them by naming the required scope (sync:execute), the risk class (read) and confirming no side effects, plus flagging that the tool is unavailable under the current authorization. It stops short of describing pagination or default result size.

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?

Two compact sentences, purpose front-loaded before the scope/risk metadata line. No filler, though the trailing unavailability clause is terse enough to be slightly ambiguous.

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, the description does say which fields are returned (estado, progresso, resultado), which helps. But the lone parameter is undocumented and there is no mention of ordering, recency window, or result count, so it is only minimally sufficient.

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?

There is one parameter (limit) with 0% schema description coverage, so the description must carry the meaning. It never mentions the limit, its default of 10, or the maximum of 50, leaving an agent to guess at page-size semantics.

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 resource and scope: recent synchronization requests, including state, progress and per-property result. It is clear what the tool returns, although it does not explicitly name how it differs from siblings like list_jobs, get_job or preview_sync.

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 'Escopo: sync:execute ... INDISPONÍVEL nesta autorização' line gives a useful operational precondition/unavailability signal. However, there is no explicit statement of when to use this versus preview_sync, start_sync, or list_jobs, so routing guidance remains implied.

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