navigate_forward

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

No annotations are provided, so the description must convey behavioral traits. It accurately indicates a safe, non-destructive read operation (navigating history). The only missing detail is what happens if there is no forward history (e.g., throws error or does nothing), but this is a minor omission.

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?

A single, complete sentence that efficiently conveys the purpose and behavior with no extraneous words. It is perfectly front-loaded and earns its place.

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 tool is simple (no parameters, no output schema) and the description fully covers its purpose and basic behavior. No additional context is necessary for correct agent usage.

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 tool has zero parameters and 100% schema coverage, so no additional parameter documentation is needed. The description is sufficient and adds no redundancy.

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 verb 'navigate forward' and the resource 'current window's history', and distinguishes itself from the sibling 'navigate_back' by specifying direction. It even includes the keyboard shortcut Alt+Right for clarity.

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 implies this is for moving forward in browser/session history, which is clear context. However, it does not explicitly state when not to use it (e.g., no forward history available) or mention the sibling 'navigate_back' as an alternative. This is a minor gap.

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