Read renderer network activity

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

No annotations are provided, so the description carries full burden. It discloses that multiple entries share requestId and must be joined, and explains the default filter behavior. This gives good insight into how the data is structured and filtered. It could be more explicit about whether the returned list is a snapshot or live, but overall it's transparent.

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 three sentences with no wasted words. It front-loads the core purpose, then adds key behavioral info. Every sentence serves a purpose, making it efficient and easy to parse.

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 the tool has 9 parameters and no output schema, the description covers the essential data lifecycle (joining requestId) and default filtering. It does not explain output structure, but that is acceptable without an output schema. It provides enough context for an agent to use the tool effectively, except possibly for edge cases like pagination or limits.

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%, so baseline is 3. The description adds value beyond the schema: it explains the default filter and how to override it with resourceType, gives an example for urlContains, and clarifies the relationship of events via requestId. This extra context helps the agent understand parameter interplay.

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 it returns CDP Network events (request/response/finished/failed) and explains the relationship between entries via requestId. It is specific about the resource (network events) and the action (returns). Among sibling tools, this is the only one retrieving network activity, making its purpose distinct.

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 useful usage context: default filter omits static assets, so only XHR/fetch calls surface, and you can override with resourceType. It implies when to use (for API requests) but does not explicitly state when not to use or compare to alternatives. However, given the sibling list, this tool is the only network-related one, so the context is sufficient.

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