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

Beyond the annotations, the description adds valuable behavioral detail: immutable field provenance, byte-identical attachments, human-review-required outputs, no citation pollution in numeric/boolean values, and a careful retry policy. It does not contradict the destructiveHint annotation, though it does not elaborate on what destructive effect occurs.

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 dense but every sentence adds a meaningful constraint or context, and the core purpose is front-loaded. It is longer than typical but justified by the complexity of the operation.

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 14-parameter, deeply nested mutation with no output schema and only 7% schema coverage, the description leaves substantial gaps: it does not explain the revision/confirmation/expectedVersion objects, the selection semantics, or what the operation returns. The safety and provenance details are helpful, but not enough for reliable invocation.

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 only 7%, so the description must compensate, but it explains only a few parameters (adaptiveRevision, adaptiveDocumentId, fieldId, draft sections, selection) and leaves required fields like planRevision, confirmationId, itemId, draftRevision, and expectedVersion unexplained. The guidance is conceptual rather than mapping to the actual input schema.

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: produce one selected item/document after exact-plan human agreement, and explains the DOCX/legacy-form contexts. It is reasonably clear, though it never names a sibling alternative and 'selected item' remains somewhat abstract.

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 clearly ties usage to exact-plan human agreement and gives specific conditional guidance: adaptive dossiers need adaptiveRevision, filling originals needs adaptiveDocumentId and fieldId, legacy forms use named draft sections. It lacks explicit exclusions or sibling comparisons, but the intended context is clear.

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