meetup_type

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

With no annotations, the description carries the full behavioral burden, yet it only states the basic typing action. It does not say whether typing replaces or appends existing text, whether the field must be visible or focused, whether the action submits anything, or what errors or return values to expect.

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 with no boilerplate or repetition. It wastes no words, though its brevity contributes to gaps assessed in other dimensions.

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 two-parameter browser action tool with full schema coverage and no output schema, the description covers the basic action and page context. However, with no annotations it omits behavioral details an agent needs before invoking, such as prerequisites and side effects, so it is adequate but incomplete.

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 100%, so both 'text' and 'element' are already defined, including 'Field number from the last read' and minimum 1. The description adds page context ('current Meetup page') but no additional parameter syntax, constraints, or meaning beyond the schema.

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 names a specific action (type text) and target (numbered field on the current Meetup page). It is clearly distinct from click/read/navigation siblings by verb and resource, though it does not explicitly name the alternatives.

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?

There is no explicit when-to-use guidance, no prerequisites such as needing a page opened or fields read first, and no mention of alternatives like meetup_click or meetup_read. The only usage cue is implicit in 'numbered field from the last read' appearing in the schema, not the description.

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