browser_console

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

There are no annotations, so the description must carry the behavioral burden. 'Read' implies a non-mutating operation and 'captured' indicates that messages are pre-recorded from the session, but the description does not say whether the console buffer persists across navigations, how stale the captured messages are, or what the tool returns when the console is empty.

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 a single sentence that states action, object, and scope with no filler. It is appropriately sized for the tool's simplicity.

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?

For a read-only console reader with optional filter parameters, this is a workable description, but it omits usage context, output format, and behavioral expectations such as message retention. It is adequate but leaves an agent to infer several things before calling.

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 description coverage is 0% and the description does not mention level or limit. The parameter names and the level enum are reasonably self-evident, but the description adds no meaning to the filters or bounds, so an agent must infer semantics from names and defaults alone.

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 uses a specific verb ('read') with a clear resource ('console messages') and a scoping qualifier ('current session'). It is meaningfully distinct from siblings like browser_network or browser_evaluate, though it does not explicitly name or contrast them.

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?

There is no guidance on when to use this tool versus browser_evaluate or browser_network, and no mention of prerequisites such as having navigated first. The only contextual hint is 'current session,' which implies scope but not selection criteria.

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