firefox_navigate

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

With no annotations provided, the description carries full burden for behavioral disclosure. It fails to mention if navigation waits for page load, error handling, or effects on tab state. 'Navigate a claimed or existing tab' is too vague for safe invocation.

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 very short, which aids scannability but sacrifices necessary detail. It could be improved by adding a sentence on behavior or parameters without becoming verbose.

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 of navigation and lack of output schema, the description still falls short. It omits key information such as whether it causes navigation, waits for load, or handles errors, making it incomplete for reliable use.

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 input schema has 50% coverage (one param described minimally, the other only by format). The description adds no additional meaning beyond the schema, missing details like URL format expectations or sessionTabId origin.

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 indicates the tool navigates a Firefox tab, distinguishing it from siblings like firefox_open_tab or firefox_back. Verb 'navigate' and resource 'tab' are specific. However, it does not explicitly mention that it navigates to a URL, leaving some ambiguity.

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 on when to use this tool versus alternatives such as firefox_back, firefox_forward, or firefox_open_tab. The description lacks any differentiation or context for choosing this tool.

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