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

No annotations provided, so description carries full burden. It discloses what data is returned (method, status, URL, size, timing) and the auto-start behavior. However, it omits read-only safety confirmation, return format details, volume limits, or pagination behavior that would be critical given zero annotation coverage.

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?

Four efficiently structured sentences with zero waste: purpose (View...), output fields (Shows...), filtering (Filter by...), and prerequisites (Network capture starts...). Information is front-loaded and every sentence earns its place.

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?

Appropriately complete for a 6-parameter read operation with 100% schema coverage. Covers viewing scope, returned fields, filtering options, and session lifecycle. Lacking output format specification (JSON structure, array vs object) which would be helpful given no output_schema exists, but this is a minor gap.

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 has 100% coverage establishing baseline 3. Description adds value by explicitly mapping parameters to filtering capabilities ('Filter by URL pattern, method, status range, or content-type'), clarifying that statusMin/statusMax function as a range and that these parameters act as filters.

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?

Clear specific verb ('View') + resource ('captured HTTP requests/responses') plus scope ('for a session'). The mention of 'viewing' vs the sibling 'network_intercept' (which implies interception/modification) provides implicit differentiation.

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?

Provides important prerequisite context that 'Network capture starts automatically when a session is created,' informing the user that manual activation isn't required. However, lacks explicit guidance on when to use this versus sibling 'network_intercept' or other session tools.

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