Network requests

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

No annotations are present, so the description must disclose behavioral traits. It only states the return behavior but does not mention whether data is cleared, if authorization is needed, or if the tool is read-only. This lack of context 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 concise with a single sentence. It is front-loaded with the action and result, but could benefit from additional context without being wordy.

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 and simple schema, the description is incomplete. It does not explain what format or content the network responses will have (e.g., list of objects with URL, status, body), nor any limitations like session timeout or number of responses.

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 coverage is 100% with one parameter (sessionId) well-defined in schema. The description adds no extra semantic value beyond the schema, which is acceptable but not helpful.

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 tool returns network responses, distinguishing it from sibling tools like browser_console_messages. However, it could be more specific about the scope (e.g., all requests, completed vs pending, inclusion of headers/body).

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?

No usage guidance is provided. The description does not indicate when to use this tool versus others (e.g., browser_snapshot for visual captures) or any prerequisites like having an active session after navigation.

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