Read renderer console messages

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

With no annotations provided, the description carries the full burden of disclosure. It reveals the source mechanism (CDP Runtime) and the type of data returned (console.* and exceptions). However, it lacks information about potential side effects, authorization requirements, or rate limits, which are important for safe tool invocation.

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 two sentences long, front-loading the core purpose and adding a practical usage hint. Every sentence contributes information without redundancy or fluff, making it highly efficient for an agent to parse quickly.

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 that there is no output schema, the description should ideally indicate the return format or structure of the console messages. It does not mention whether the returned data includes message text, timestamp, source, etc. While the schema parameters imply some output context, the description itself is incomplete for an agent to understand the full tool behavior.

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?

The input schema covers all parameters with descriptions, achieving 100% coverage. The description adds marginal value by mentioning the 'level' filter in context, but does not provide additional semantics beyond what the schema already conveys. Thus, it meets the baseline for high schema coverage.

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 title and description explicitly state it returns console.* output and unhandled exceptions from the renderer, captured via CDP Runtime. This clearly distinguishes it from sibling tools like get_main_logs or get_network_requests by specifying the source (renderer) and content type (console messages and exceptions).

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 a usage example with the 'level' parameter to filter errors, which implies when to use the tool. However, it does not explicitly state when not to use it or suggest alternative tools for different logging needs, leaving the agent to infer usage context.

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