comet_navigate

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

With no annotations, the description bears the full burden of behavioral disclosure, but it only states the navigation action and lists wait conditions. It does not disclose side effects such as replacing the current page, altering history, or whether a connection to Comet is required.

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 short, front-loaded with the primary purpose, and the arguments block is compact. The wait_for enumeration earns its place, though the url line is somewhat redundant with the parameter name.

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 low-complexity tool with two parameters and an output schema, the essential calling information is present. However, the lack of usage context and side-effect disclosure leaves an agent without enough behavioral context to anticipate the tool's impact on the browsing session.

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 must compensate. It gives url a clear role and enumerates the accepted wait_for values, adding real meaning beyond the schema. It stops short of specifying URL format requirements, but it covers both parameters adequately.

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 and resource ('Navigate Comet to a specific URL') and is clearly distinct from sibling tools that screenshot, search, read, click, type, or evaluate. However, it does not explicitly differentiate itself from a similar navigation-related sibling, so it stops short of a perfect score.

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 provided on when to use this tool versus alternatives. There is no mention of exclusions, prerequisites, or conditions that would make comet_search or comet_read_page more appropriate instead.

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