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

The description adds meaningful behavioral context beyond the annotations: it states that the download rechecks evidence, revisions, access and expiry, and that it does not auto-submit to buyers. Annotations already indicate destructiveHint and idempotentHint, and the description does not contradict them. It provides some added value but not extensive detail.

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 concise and front-loaded with the main purpose. Each sentence adds distinct value: purpose, prerequisites, download recheck behavior, and no auto-submission. No fluff or redundant restatement of the tool name.

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 tool with six required parameters, nested objects, and no output schema, the description is insufficient. It lacks guidance on parameter construction, how to obtain the resulting ZIP, or any details about return values. An agent would struggle to invoke this correctly without additional context from other tools or prior knowledge.

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 17% (only idempotencyKey has a description). The description does not explain any of the six required parameters, including the nested objects (documents, selection, planRevision) and confirmation IDs. With such low coverage, the description should compensate but does not, leaving agents uncertain about how to construct valid arguments.

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 action: exporting exact approved file versions and a hash manifest as a ZIP. This clearly identifies the resource and format, and distinguishes it from siblings like helvabase_export_dossier or helvabase_export_requirement_coverage by focusing on exact approved versions. However, it does not explicitly name those alternatives, so it stops short of 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?

The description provides prerequisites (requires current file reviews and final pack confirmation) and notes that there is no automatic buyer submission, giving context for when to use it. It does not explicitly state when not to use it or name alternative tools, so guidance is present but not fully explicit.

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