browser_configure

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

No annotations are provided, so the description carries full burden. It reveals the configuration action and call order but does not mention error behavior (e.g., invalid proxy format) or side effects beyond configuration. Still, it covers the main behavioral intent well.

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 front-loaded with purpose, followed by usage guidelines, then parameter explanation. Every sentence serves a purpose, with no redundant text. Ideal conciseness.

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 only one optional parameter, no required params, and a simple purpose, the description fully covers what the agent needs: purpose, usage, parameter details, and return value. No gaps for this complexity level.

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%, so the description fully compensates by detailing proxy formats in four variations. This adds significant meaning beyond the schema's mere type definition.

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 configures proxy before launching a browser, using specific verb 'Configure' and resource 'proxy'. It distinguishes from sibling tools like browser_navigate and browser_install by focusing on proxy configuration.

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?

Explicit instructions 'Call BEFORE browser_navigate. If browser running, call browser_close first.' provide clear when-to-use and prerequisites, which is excellent for agent guidance.

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