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

Goes well beyond the annotations: annotations only declare this is a non-read-only, non-destructive, idempotent write. The description adds that no review-confirmation email is sent, nothing is approved, review copies are visibly marked unapproved, findings appear as Word comments plus a review appendix, and the submission edition cannot be overridden. All of this is behavior an agent could not infer from 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?

Five dense sentences, purpose front-loaded, with each sentence carrying either edition semantics or behavioral constraints. There is mild redundancy between 'does not send a review-confirmation email or approve anything' and 'Review copies are marked unapproved', but no filler.

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 mutation tool with a nested input object, no output schema and 50% schema coverage, the description covers editions, permitted draft quality, output artifacts and confirmation requirements well. It does not say what is returned (presumably an output job for helvabase_output_download), which is the remaining gap since no output schema exists.

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 coverage is 50%, and the biggest gap is the 'edition' enum, which has no schema description; the description fully explains what review and submission mean, which is exactly the compensation needed. It also implies that 'revision' pins an exact immutable draft (outputJobId + payloadHash). Remaining minor gap is that the nested revision fields and the output-job return path are not elaborated, but the description carries its share.

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?

Names a specific verb and artifact: build a professional DOCX for the exact immutable draft, and enumerates the two editions (review/submission). An agent can tell it produces a localized DOCX export of a frozen revision. It does not, however, explicitly distinguish itself from close siblings such as helvabase_export_document_pack or helvabase_produce_document, so a 4 rather than a 5.

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?

Clearly states the conditions that select each edition: review is permissible for working drafts with open questions, unsupported claims or qualification gaps, while submission requires current source validation and reviewer confirmation with no override. That is concrete when-to-use guidance. It stops short of naming alternative tools or explicit when-not-to-use conditions, so not a 5.

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