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

Annotations are absent, so the description carries the full load. It discloses the key behavioral trait (automatic navigation, no clicking required) and contrasts with get_page_link. It does not mention auth requirements or what happens on the current page, but for a navigation tool the disclosure is solid.

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 emoji, caps-lock emphasis, and long trigger-phrase list make it verbose front-loaded but somewhat noisy. The essential information (automatic navigation, use vs get_page_link) could be stated in half the space, and the page category list duplicates schema information.

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 single-parameter navigation tool with no output schema, the description covers all an agent needs: what it does, when to use it, when not to, and points to the alternative. Nothing critical is missing.

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% and the page enum is fully defined in the schema. The description lists page categories but does not add format/syntax meaning beyond what the schema already enumerates. Baseline 3 is appropriate here.

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?

States a specific verb+resource: navigates the user to a page, and front-loads the key behavior (AUTO/IMMEDIATELY). It is unambiguous and distinguishable from siblings like get_page_link, which it explicitly names.

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?

Explicitly lists trigger phrases for when to use it and calls out when NOT to use it, directing to get_page_link instead. This is a textbook example of when/when-not/alternative guidance.

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