boj_browser_navigate

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

No annotations are provided, so the description carries full burden for behavioral disclosure. 'Navigate Firefox to a URL' implies a state-changing operation (browser navigation), but doesn't disclose important behavioral traits: whether this opens a new tab or uses current tab, what happens if navigation fails, whether it waits for page load, authentication requirements, or rate limits. The description is minimal and lacks operational context.

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 maximally concise - a single sentence with zero wasted words. It's front-loaded with the core action and resource. Every word earns its place: 'Navigate' (action), 'Firefox' (target), 'to a URL' (resource/destination).

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 browser navigation tool with no annotations and no output schema, the description is insufficiently complete. It doesn't explain what happens after navigation (does it return success/failure? page title? status?), doesn't mention potential side effects (tab creation, history updates), and provides no context about the Firefox instance being controlled. Given the operational nature of browser automation, more behavioral context is needed.

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 100% with the single parameter 'url' clearly documented in the schema. The description doesn't add any parameter semantics beyond what the schema provides (it doesn't specify URL format requirements, validation rules, or examples). With high schema coverage, baseline 3 is appropriate as the schema does the parameter documentation work.

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 action ('Navigate Firefox') and resource ('to a URL'), making the purpose immediately understandable. It doesn't explicitly differentiate from sibling browser tools like 'boj_browser_read_page' or 'boj_browser_tabs', but the verb 'navigate' is specific enough to distinguish it from other browser interactions.

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 no guidance on when to use this tool versus alternatives. With multiple sibling browser tools available (like 'boj_browser_read_page' for reading content or 'boj_browser_tabs' for tab management), there's no indication of when navigation is appropriate versus other browser operations.

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