C2.9/5.0

Behavior3/5

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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, so the safety profile is carried by structured data. The description adds one genuinely useful behavior — it returns the post-action observation, so the agent should re-read state after calling. It does not, however, explain what makes the action destructive (e.g. that selection may submit a form or trigger navigation).

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?

Two short sentences, front-loaded with the action, no filler. Efficient, though the second sentence is more informative than the first.

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

Completeness2/5

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 explained, but for a destructive, non-idempotent UI action with two completely undocumented required parameters the description leaves too much open: no workflow state requirement, no clarification of what 'description' matches against, no note on side effects.

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

Parameters2/5

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

Schema description coverage is 0% and neither parameter has any schema text, so the description carries the full burden. Saying 'by description and value' just renames the parameters; it never clarifies whether 'description' is the visible option label, a natural-language description used for matching, or the dropdown's own description.

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?

States a specific verb and resource: selecting a dropdown option, plus which inputs identify it. It is distinguishable from siblings like type_into and click_what, though it never says how it differs from simply clicking the option.

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?

No guidance on when to use this versus click_what or type_into, no preconditions (dropdown must be open? element already located?), and no exclusions. The agent must infer the whole workflow context.

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