navigate

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

With no annotations provided, the description carries the full behavioral burden and discloses the critical rule that three origin violations end the run. It also clarifies that relative URLs resolve against the current page. It does not cover other behavioral details such as redirect handling or load/wait semantics, but the key safety constraint is clearly surfaced.

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 short sentences and front-loads the core action before the constraint. Every phrase adds useful information, including accepted URL forms and the termination rule.

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?

An output schema exists, so the description need not explain return values. For a one-parameter navigation tool with no annotations, it covers the essential invocation constraint and the consequence of origin violations. It could be slightly more complete by clarifying navigation timing or redirect behavior, but the key information is present.

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 schema has a single required url parameter with 0% description coverage, so the description must add meaning. It does so by explaining that the URL may be absolute or relative to the current page, which is directly useful for correct invocation.

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 states a specific action, 'Go to url', and clarifies accepted URL forms (absolute or relative to the current page). It is clearly distinct from sibling browser tools like click and read_page, though it does not explicitly name or contrast those alternatives.

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 an implied usage context for direct URL navigation and states an important constraint: the URL must stay on the session's origin. However, it does not explicitly say when to prefer navigate over alternatives such as click, and it does not mention exclusions or prerequisites beyond the origin rule.

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