`timeout`	No	Shared maximum seconds for target resolution, click, and download completion.
`selector`	Yes	Selector/accessibility target, viewport coordinate click, or keyboard input that starts one download.
`operation_key`	No	Optional live-task key. Reusing the same key replays the frozen artifact result without clicking again.
`expected_filename`	No	Optional exact basename constraint for the downloaded artifact.
`expected_mime_type`	No	Optional MIME constraint inferred from the completed filename.

B3.2/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=false, destructiveHint=true, and openWorldHint=true, so the side-effect profile is covered. The description adds that exactly one trigger is performed, that the call blocks until one download completes, and that the result is an integrity-checked artifact receipt — useful behavioral context the annotations do not convey. It does not disclose timeout/failure semantics or what 'safe' means concretely.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence that leads with the trigger action and ends with the deliverable. It is dense but free of filler; it could be slightly shorter but nothing is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The output schema is present so return-value explanation is unnecessary, and annotations cover the safety profile. However, for a blocking, destructive download operation, the description omits failure/timeout behavior and the single-download constraint's consequences, leaving the agent to rely on schema defaults.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents tab_id, timeout, operation_key replay, expected_filename, and expected_mime_type constraints. The description adds only the trigger-type enumeration, which the discriminator schema already provides. Baseline 3 applies when the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

Names a specific verb set (trigger + await download + return receipt) and a concrete resource (one completed download artifact). Read against siblings like element_click and element_click_and_upload, it is clear this tool is the download variant. It is slightly imprecise in enumerating only 'selector, coordinate, or keyboard' triggers while the schema also supports an accessibility target.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit statement of when to pick this tool over element_click, page_click_xy, or element_click_and_upload, nor any condition/antecedent for use. The 'await one completed download' phrasing only implies usage; an agent must infer the selection rule from the name.

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