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

No annotations are provided, so the description carries the full behavioral disclosure burden. It explains the workflow but does not say what 'finalizing' actually does: whether it mutates state, creates a document, costs money, is reversible, needs authentication, or has rate limits. The agent gets procedural guidance but little insight into side effects or risk.

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 mostly front-loaded: purpose first, then usage condition, then parameter guidance. The final example sentence largely repeats the preceding parameter guidance, which is minor redundancy, but overall it is efficiently structured.

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?

For a patch/finalize tool with no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It omits the required request_id parameter and does not describe the result of finalization or any side effects. The workflow hint helps, but an agent still lacks essential calling context.

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 that 'id' is the chosen option from the prior search and that 'year' may apply to balance sheets, which is helpful. However, the required 'request_id' parameter is never mentioned or explained, leaving a critical gap for a 3-parameter tool.

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 states a specific verb and resource: finalize selection for the Bilancio XBRL DocuEngine service. It also explicitly ties itself to the preceding search sibling docuengine_bilancio_xbrl, so an agent can place it in the workflow. It does not, however, distinguish itself from the other patch_docuengine_* siblings beyond the service name.

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 gives clear usage context: call this AFTER docuengine_bilancio_xbrl returns a list of options. It tells the agent what to pass (id, and year if applicable). It does not state when not to use it or mention other alternatives, so it falls short of a full 5.

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