browser_navigate

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

With no annotations provided, the description must disclose behavioral traits such as what happens on navigation failure, whether it waits for page load, or if it modifies browser state (e.g., history). The only constraint given is the URL pattern, leaving significant gaps about side effects and outcomes.

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 concise sentence that front-loads the action. However, it lacks punctuation for readability and could benefit from a slight expansion on 'explicitly shared tab' without losing conciseness.

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 tool's moderate complexity (3 parameters, no output schema) and lack of annotations, the description is insufficient. It does not explain the return behavior or what 'success' means, and key parameter semantics are missing. The sibling context includes many other browser tools, but the description does not help differentiate when to use this one over similar navigation 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 0%, so the description should add meaning to all parameters. 'Navigate one explicitly shared tab to an exact same-origin HTTPS URL' explains the 'url' parameter partly (HTTPS constraint) but ignores 'collaboration_id' and 'ignore_cache'. The purpose of 'collaboration_id' is unclear, and 'ignore_cache' is not mentioned at all.

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' and resources 'explicitly shared tab' and 'same-origin HTTPS URL'. The constraints like 'exact same-origin' and 'HTTPS' differentiate this from a general 'go to page' action. It is clear but could add context about what 'explicitly shared tab' means compared to sibling tools like 'browser_open'.

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 lacks guidance on when to use this tool versus alternatives like browser_open. 'Explicitly shared tab' is ambiguous without context on how tabs are shared or what qualifies. There is no when-not-to-use or prerequisite information, such as requiring an existing shared tab first.

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