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

Annotations include readOnlyHint=false and destructiveHint=false, but the description says '[write, altera dados]' and 'DELETE', which implies deletion. However, destructiveHint=false contradicts the notion that deletion is destructive. The description adds the bulk execution note but does not clarify side effects, irreversibility, or authorization. The contradiction with destructiveHint is notable.

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 short and includes the endpoint and bulk support. It is front-loaded with the core purpose. However, the note '[write, altera dados]' is redundant given the annotations and the DELETE verb, so a slight waste. But overall, it is efficient.

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 simple delete tool with no output schema, but the description does not cover critical aspects like error handling, idempotency, or the effect of deletion. Given the annotations are sparse (no idempotent hint), the description should provide more context but doesn't. It is minimally adequate for a simple tool but has gaps.

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 description should compensate. The description only mentions 'ids' for batched execution, but does not explain 'id', 'body', or 'account'. Even the id parameter is unclear in terms of format or required context. With 4 parameters and 0% coverage, this is a significant gap.

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 the tool's verb ('Excluir atividade'), the resource (activity), and the HTTP DELETE endpoint. It also mentions bulk support. However, it doesn't explicitly differentiate from sibling tools like datacrazy_activities_patch or datacrazy_activities_create, though the DELETE verb inherently distinguishes it.

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 does not explain when to use this tool versus alternatives. It only mentions the endpoint and bulk support. There is no guidance on prerequisites (e.g., authentication) or scenarios where deletion is appropriate, which is insufficient for an agent to decide between this and other activity tools.

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