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

No annotations are provided, so the description carries the full behavioral burden. It calls this a 'finalize' step but never says what actually happens (does it create/queue a document, charge, mutate a prior request?), whether it is idempotent, or what it returns. For a mutation tool with zero annotation coverage this is a significant gap.

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 core instruction is front-loaded, but the closing 'Example:' sentence largely restates the preceding sentence about passing 'id' and 'year', adding little new information and inflating the text.

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?

With no output schema, no annotations, and 0% schema coverage across 3 params, the description should close more gaps than it does. It conveys the workflow but omits the required 'request_id' semantics and any side-effect/return behavior, leaving an agent under-informed for a mutation call.

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 must compensate. It explains 'id' ('from your chosen option') and 'year' ('if applicable, e.g., balance sheets'), which is genuinely useful, but it never mentions the required 'request_id' parameter at all, leaving a required field entirely undocumented.

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 ('Finalize selection') and a specific resource ('DocuEngine service: Atto Ottico'), and it clearly positions the tool as a follow-up step. It is distinguishable from most siblings, though it doesn't explain what 'Atto Ottico' actually yields or what 'finalize' produces.

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?

It gives an explicit precondition: use this AFTER calling 'docuengine_atto_ottico' when it returns a list of options. That is a clear when-to-use signal with an alternative named. It does not, however, mention when NOT to use it or distinguish it from the identically-shaped 'patch_docuengine_*' siblings.

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