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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=false, so the write behavior is disclosed without description. The description adds the endpoint and the 'data' body convention, but does not go into auth requirements, error behavior, or return format; with annotation coverage, this is adequate but not rich.

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?

The description is two short, front-loaded sentences: first the purpose/endpoint, then the key payload instruction. No redundant phrases or filler.

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?

The tool is a simple passthrough wrapper with one opaque parameter and no output schema; the description covers its purpose and payload pointer. It is not fully self-contained (no official API link, example, or return value details), but it is reasonably complete for a generic create wrapper with annotations.

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, 'data', and although the schema only shows an open object, the description adds semantic meaning by stating that 'data' is the request body 'conforme a API oficial'. This tells the agent to follow the official API contract rather than treating the object as arbitrary, partially compensating for the 0% schema coverage.

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 opens with 'Cria' + 'Apontamento de horas (timesheet)' and includes the precise endpoint 'POST /apontamento-horas', so the verb, resource, and operation are specific. The create action is clearly differentiated from siblings like projuris_consulta_apontamento_horas and projuris_update_apontamento_horas.

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 description makes it clear this tool is for creating a timesheet entry and is not a read/update operation; the POST verb and resource provide clear context for when to use it. It does not explicitly name alternatives or set exclusions, so it stops short of a 5.

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