browser_forward

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

Discloses no-op behavior for empty history, which adds value beyond annotations. Annotations already indicate possible side effects (openWorldHint=true) and idempotency not guaranteed (idempotentHint=false). Description complements these well.

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?

Extremely concise: one sentence for action and no-op, one sentence for sibling pairing. No redundant words.

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?

Given the simplicity (0 parameters, no output schema, simple navigation), the description covers the essential behavior. However, it lacks mention of return value or state changes beyond the no-op, which is minor.

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?

Tool has no parameters; schema coverage is 100%. Description doesn't need to add parameter semantics, and baseline for 0 params is 4. No additional information needed.

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?

Clearly states the tool's purpose: 'Go forward one entry in the active pane's history' and distinguishes from siblings like browser_back and browser_navigate.

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 tells when to use (navigate forward), when it's a no-op (nothing to go forward to), and provides alternative: 'use browser_navigate to go to a new URL'.

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