play_data_safety_export

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

With no annotations, the description carries full behavioral burden and does so well: it discloses that the download requires Browser.setDownloadBehavior (and that Page. does not work) and that the file arrives with a GUID name before being renamed. That is meaningful quirk information an agent could not get elsewhere. It stops short of covering auth needs, overwrite behavior at destination_dir, or failure modes.

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?

Three sentences with the core action front-loaded in the first line, followed by supporting context. The middle sentence is justificatory rather than instructional, but it is compact and earns its place by explaining the CSV advantage.

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?

An output schema exists, so return values need not be described, and the download quirks are well covered. However, for a 2-parameter tool at 0% schema coverage, the description leaves parameter semantics and prerequisite conditions unexplained, making it only minimally sufficient.

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% for both params, so the description must compensate, but it never explains what package_name or destination_dir mean or their expected format. It mentions the renamed output file, which hints at destination_dir semantics, but leaves package_name entirely unexplained.

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?

States a specific verb and resource: 'Download the Data safety declaration CSV template.' An agent can immediately tell this produces a CSV file. However, it never distinguishes itself from the closely related sibling tools play_data_safety_import and play_data_safety_fill, which an agent could easily confuse with this one.

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 explains why the CSV path is preferable ('much faster and more reliable than clicking screen by screen'), which implies the intended workflow, but it never explicitly says when to use this versus play_data_safety_import or play_data_safety_fill. Usage must be inferred from the wizard context rather than stated as a routing rule.

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