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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only states 'Adiciona' (adds), implying a mutation, but gives no indication of side effects, authentication requirements, reversibility, or any other behavioral context.

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 a single sentence with no fluff, but it is under-specified for a tool with five parameters and no annotations. It is not concise in the sense of packing necessary value; it merely states the obvious purpose without covering any of the behavioral or usage context expected for this complexity.

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?

This is a creation tool with five parameters, no output schema, and no annotations, so the description needs to compensate. It provides only the bare minimum purpose statement, lacking any guidance on when to use, expected outcomes, or parameter context. The description is completely inadequate for the tool's complexity.

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?

The input schema has 100% description coverage for all five parameters, so the baseline is 3. The description adds no additional parameter meaning beyond what the schema already provides, but this is acceptable given the schema's robust documentation.

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 clearly states a specific verb ('Adiciona') and resource ('nova página ao diário espiritual'), making the tool's function unambiguous. It is distinct from sibling tools like create_prayer_request or list_spiritual_journal, though it does not explicitly differentiate itself.

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?

No guidance is provided on when to use this tool versus alternatives. The description only states what the tool does, with no mention of prerequisites, exclusions, or contexts where another tool would be more appropriate.

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