get_dropdown_options

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 states the return values (options, id, and name) but lacks critical details: whether this is a read-only operation, if it requires specific permissions, potential errors (e.g., invalid session or index), or performance implications. For a tool interacting with browser elements, this is a significant gap.

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, efficient sentence that front-loads the core purpose. It avoids redundancy and wastes no words, though it could be slightly more structured (e.g., separating purpose from return values). Overall, it's appropriately concise for the tool's complexity.

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?

Given the tool's moderate complexity (2 required parameters, browser interaction), no annotations, and an output schema (which handles return values), the description is minimally adequate. It covers the purpose and output but misses parameter semantics and behavioral context. With the output schema reducing the need to detail returns, it's complete enough for basic use but leaves gaps for robust agent operation.

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%, so the description must compensate for undocumented parameters. It mentions no parameters at all, failing to explain what 'session_id' and 'index' represent or how they relate to dropdown elements. This leaves both parameters semantically unclear beyond their titles in 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 clearly states the verb 'Get' and the resource 'options from a dropdown/select element', specifying what the tool does. It distinguishes from siblings like 'get_element_info' by focusing specifically on dropdown options rather than general element information. However, it doesn't explicitly contrast with other dropdown-related tools (none appear in the sibling list), so it's not a perfect 5.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an active browser session), compare to similar tools like 'get_element_info', or specify scenarios where this tool is preferred. The agent must infer usage from the purpose alone.

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