timezest_navigate

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

No annotations are present, so the description carries the full burden of disclosing behavioral traits. It states the action but does not mention side effects (e.g., whether the current domain is changed for subsequent calls), authentication requirements, or what the tool returns. This is minimal disclosure for a state-changing operation.

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 sentence that conveys the essential purpose without redundancy. It is appropriately concise for a simple navigation tool with only one parameter.

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?

The tool has no output schema and the description does not explain what the tool returns or how navigation affects subsequent operations. For a tool that changes context, the lack of information about side effects and return value is a significant gap, even though parameters are well-documented.

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 fully documents the domain parameter with an enum and a description, giving 100% schema coverage. The description adds no additional meaning about the parameter, so the baseline score of 3 is appropriate.

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 states a clear verb 'navigate' and a resource 'TimeZest domain', distinguishing it from the sibling tool timezest_status which presumably checks status. However, 'to access its tools' is somewhat vague about the operational effect, so it doesn't fully meet the 5-level of specificity.

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 explicit guidance is provided on when to use this tool versus alternatives. It does not mention timezest_status or any exclusion criteria. The only implicit usage is derived from the purpose, which is not enough to guide an agent in tool selection.

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