refresh_exam_browser

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

No annotations are provided, so the description carries the full behavioral burden. It discloses parsing a DOM observation from the same tab, but not whether it refreshes or navigates, mutates state, requires authentication, or how errors are handled; this is thin for a four-required-parameter operation.

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?

It is a single front-loaded sentence with no filler. The phrase 'fresh current-question DOM observation' is dense, but the statement is efficiently structured and every word is doing work.

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?

The output schema means return values need not be described, but the definition still omits when to use the tool, what the four required inputs mean, and what the parse achieves. With no annotations and 0% schema description coverage, this is insufficient for a complex exam-browser 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%, and the description does not mention run_id, tab_id, exam_url, or html_source by name. It weakly implies html_source is the DOM observation and tab_id is the browser tab, but run_id and exam_url remain completely unexplained.

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?

States a specific verb ('Parse') and resource ('fresh current-question DOM observation') and anchors it to 'the same browser tab.' It is clear enough to distinguish from generic browser observation tools, but it does not name or compare against siblings such as prepare_exam_browser_step or read_current_exam_question.

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, prerequisite, or alternative guidance. 'Fresh' and 'same browser tab' weakly imply it follows a page refresh, but an agent must infer that; there is no indication of when to choose it over examine/read/observe siblings.

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