navigate_page

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

Annotations only declare readOnlyHint=false, so the description adds some value by naming navigation modes and the default project URL behavior. However, it does not disclose side effects such as page state loss, dialog handling, or script execution behavior during navigation.

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?

Two short sentences with no wasted language, and the core navigation behavior is front-loaded. The default-URL note is useful and compact.

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?

The schema is fully described and no output schema exists, which reduces the description's burden. Still, for a seven-parameter navigation tool, the description is terse and leaves important context implicit, especially around default type behavior and how this differs from related page tools.

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%, so the schema already documents all seven parameters thoroughly. The description only adds a default-URL hint and broadly names the navigation modes, without meaningfully elaborating on pageId, timeout, initScript, ignoreCache, or handleBeforeUnload.

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 verb and resource: navigating a page by URL or through history actions. It is clear what the tool does, but it does not explicitly distinguish itself from siblings such as new_page or select_page.

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 only usage-like guidance is a default behavior: 'Use project URL if not specified otherwise.' There is no explicit guidance on when to choose this tool over new_page, select_page, or other navigation-related siblings.

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