browser_console_messages

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

With no annotations, the description carries full burden but omits behavioral details such as whether the console is cleared after retrieval, prerequisites (e.g., page must be loaded), or side effects. The level hierarchy is explained but broader behavioral context is missing.

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 and structured with Args and Returns sections. It front-loads the core purpose. While efficient, a bit more context on the resource (browser console) could improve it without bloat.

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 presence of an output schema, the description adequately covers return values implicitly. However, it lacks context about what console messages are (browser console) and how this tool relates to sibling tools for network requests or dialogs. It is minimally complete for a simple tool but leaves gaps for an agent.

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 explanation of the 'level' parameter adds significant value beyond the schema: it clarifies the hierarchical inclusion of severity levels and the default value. Since schema description coverage is 0%, the description fully compensates for the gap.

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 all console messages with a specific verb and resource. However, it does not differentiate from sibling tools like browser_network_requests or browser_handle_dialog, missing an opportunity to clarify unique functionality.

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 guidance is provided on when to use this tool versus alternatives or when not to use it. The description simply states the function without contextual cues for appropriate invocation.

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