zia_get_time_interval

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

Annotations already declare readOnlyHint=true. The description restates 'read-only', which is consistent but adds no new behavioral detail beyond confirming safety. No additional traits such as side effects, permissions, or rate limits are disclosed.

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 extremely concise: a single sentence with the key action and constraint. It is front-loaded with the verb and resource, and every word earns its place. No unnecessary fluff.

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 simple read operation with two parameters and no output schema, the description is adequate. It specifies what the tool does and its read-only nature. However, it could improve by hinting at what data is returned (e.g., time interval object with start/end times), but given the tool's simplicity, this is a minor gap.

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 coverage is 100%, so the baseline is 3. The description does not elaborate on parameter meaning or constraints beyond what the schema provides, such as format of interval_id or the default for service. Thus it adds no extra semantic value.

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 'Get', the resource 'ZIA Time Interval', and the method 'by ID'. It also explicitly labels it as 'read-only', distinguishing it from a potential list operation such as 'zia_list_time_intervals' which retrieves all intervals.

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 does not provide explicit guidance on when to use this tool versus alternatives like 'zia_list_time_intervals'. While the purpose is clear, the agent must infer that this single-item retrieval is appropriate when a specific interval ID is known. No when-not-to-use or alternative names are given.

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