interceptor_browser_screenshot

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

No annotations are provided, so the description carries the burden. It discloses the key behavioral trait: saving to file or reporting byte count. However, it does not mention if the tool waits for page load, timeouts, or whether it is destructive (though screenshots are generally read-only). The term 'bound page' is somewhat ambiguous.

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?

Two sentences with no wasted words. The most important information (action, conditional behavior) is front-loaded. Every sentence adds value.

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 no output schema, the description covers the return behavior (byte count) but lacks details on error handling, page load waiting, or differentiation from sibling interceptor_browser_snapshot. The complexity is low, so it is adequate but not thorough.

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?

Input schema has 100% coverage for all 5 parameters, so baseline is 3. The description adds value by explaining the conditional role of file_path, but does not elaborate on format, full_page, or quality beyond what the schema already provides.

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 ('take a screenshot'), resource ('bound page'), and conditional behavior (file path or byte count). It is specific and distinct from sibling tools like interceptor_browser_navigate or interceptor_browser_evaluate.

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 implies usage after launching a page but does not provide explicit guidance on when to use this tool versus similar alternatives like interceptor_browser_snapshot. No when-not-to-use or exclusion criteria are given.

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