wavexis_browser_version

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

Annotations already indicate readOnlyHint=true and idempotentHint=true, so no additional safety disclosure needed. The description adds the output structure (returns JSON with 'version' and 'backend'), which is helpful. However, it does not mention edge cases like what happens if the backend is unavailable or if session_id is 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 short and front-loaded with the key purpose. The args/returns section is slightly verbose due to docstring style, but overall it is efficient with no superfluous content.

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 read-only tool with good annotations and an output schema, the description is mostly adequate. However, the lack of parameter explanations and usage guidance makes it incomplete for an agent to use correctly, especially given low schema coverage.

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 input schema has 0% description coverage for parameters, and the description merely paraphrases the schema ('input: Browser version parameters') without explaining the meaning of 'backend' or 'session_id'. An agent would not know that 'backend' likely specifies the automation protocol (e.g., 'cdp') or how 'session_id' affects the query.

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 action ('Get') and the resource ('the browser version string'). It is specific and unambiguous, and distinguishes from sibling tools like wavexis_session_info which returns session details rather than version.

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. For example, it does not mention that wavexis_session_info might also return a version or that this tool is lightweight. No exclusions or context about when not to use it.

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