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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, and the description usefully adds what the tool does NOT do: it neither submits a request nor reserves or confirms a place. That side-effect clarification is real value beyond the annotations.

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 sentences, the purpose front-loaded before the caveats, no filler. Slightly dense phrasing ('one exact organization, publication and expected version') costs a bit of readability but nothing is wasted.

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?

Annotations cover the safety profile and an output schema exists, so return values need not be described. The remaining gap is parameter meaning: with 0% schema coverage, an agent gets no explanation of why expectedVersion matters or how the visit enum behaves.

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% across 4 parameters, so the description must carry the burden. It loosely echoes three required params ('one exact organization, publication and expected version') but never explains expectedVersion's concurrency role, and the 'visit' trial/regular enum is only obliquely referenced via the trial sentence.

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?

States a specific verb and resource ('Prepare a canonical PT-BR OiAir form link') plus the exact scoping dimensions (organization, publication, expected version), which clearly separates it from generic siblings like get_offering or search_activities. It stops short of naming an alternative sibling, so it misses the top mark.

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?

Gives a concrete precondition ('Trial requires that the selected group offers a trial') and explicitly scopes the action out ('opening the link and submitting a request are separate actions'). No alternatives are named, but the when-to-use context is clear.

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