navigate

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

No annotations are provided, so the description must carry the full behavioral burden. It only says it loads an address without typing; it does not disclose side effects, whether the current page is replaced, timeout behavior, or any browser-state prerequisites.

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 very short and front-loaded, but it is cryptic and relies on comparison to another tool rather than directly explaining behavior. It is concise without being sufficiently structured for correct invocation.

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 three-parameter navigation tool with no annotations and no output schema, the description is substantially incomplete. It omits page selection, timeout semantics, side effects, and the relationship to open_url, leaving important invocation context unstated.

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 only 33%, with only the 'page' parameter documented in the schema. The description mentions 'address' but does not explain the 'url' or 'timeout' parameters, nor does it add meaning beyond the schema.

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 and resource: loading an address. It is clear enough as a navigation operation, but it does not explain how 'navigate' differs from the sibling 'open_url' beyond the vague phrase 'same as open_url (no typing).'

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 references open_url but does not say when to choose navigate over open_url or type_text. There is no guidance about prerequisites, page selection, or timeout usage, so the agent must infer the intended usage.

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