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

Annotations only cover readOnly/destructive/idempotent hints, so the description usefully adds scope (operations:write), risk level, the affected entity, and a non-obvious side effect (concluir libera bloqueio vinculado). The availability warning also warns the agent before attempting a call. It stops short of describing partial-update behavior for omitted fields.

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, front-loaded blocks: fields first, then scope/risk/effects/availability in a scannable delimiter-separated line. Little waste, though restating the status enum values duplicates the schema.

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 mutation tool with 7 undocumented parameters and no output schema, the description conveys the main side effect and authorization state but omits partial-update semantics, whether nulling assignee/due_date is meaningful, and response behavior. Adequate but with clear gaps given the 0% schema coverage.

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%, so the schema names the 7 properties without explaining them. The description covers status, priority, assignee, cost and due date, but re-quotes enum values already in the schema and leaves the required id and the description field unaddressed.

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 names a specific verb (Atualiza) and resource (um chamado) and enumerates the mutable fields, so it is distinguishable from update_task and update_housekeeping_status. It does not name the entity type explicitly in the first sentence, but the effects clause clarifies it updates a MaintenanceTicket.

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?

Usage context is only implied — the effects clause says completing a ticket releases a linked block, which hints at when the status change matters. There is no explicit statement of when to prefer this over update_task or create_maintenance_ticket, and no prerequisites or exclusions beyond the availability note.

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