navigate

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

With no annotations, the description must carry the behavioral disclosure burden. It only says navigate and 'wait for it to settle', which hints at blocking behavior but does not explain side effects, what happens to the current page, or what 'settle' means. It also does not mention any permissions, rate limits, or failure behavior.

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 a single, front-loaded sentence with no filler. Every word contributes to the core action, making it easily parsable.

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 tool with ive params, an enum, and no output schema or annotations, this description is too sparse. It omits contextual details like default tab behavior, background navigation implications, timeout semantics, and return value. The schema covers defaults and constraints, but the description does not enrich the call context.

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 0%, and the description adds little parameter -specific meaning beyond the schema's own property names. It implies url and tab_id, and hints at wait_until / timeout with 'wait for it to settle', but it does not explain background, timeout_ms, or the wait_until enum values.

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 uses a specific verb ('Navigate') and identifies the resource ('a tab' to 'a URL'), making the core action clear. It also distinguishes itself from the sibling navigate_history by emphasizing a URL destination rather than history traversal, though it does not explicitly name the alternative.

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?

No guidance is given about when to use this tool versus alternatives like navigate_history, search, or wait_for_load. The description merely states what the tool does, leaving the agent to infer usage context on its own.

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