click_by_overlay_id

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the click action and the overlay ID source; it does not mention potential side effects, timing, page-load requirements, or what happens if the overlay ID is stale/invalid.

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 a single, front-loaded sentence that immediately states the action and target. It contains no unnecessary elaboration, making it concise and scannable.

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 simple one-parameter click tool, the description provides the essential context: what to click and where the ID comes from. It could mention the need to generate a visual map first, but the sibling context and the phrase 'from the visual map' make this reasonably inferable.

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?

The schema already fully describes overlayId as 'The number shown on the visual overlay' (100% coverage). The description repeats the concept without adding new parameter detail, so a baseline score of 3 is appropriate.

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 uses a specific verb ('Click'), identifies the resource ('an element by its overlay ID'), and names the source ('from the visual map'). This clearly distinguishes it from sibling tools like hover_by_overlay_id.

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?

No explicit guidance is given on when to use this tool versus alternatives such as hover_by_overlay_id. The description implies usage when an overlay ID has been obtained, but it does not state prerequisites, exclusions, or alternative choices.

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