create_schedule_time_range

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

Annotations already indicate a non-read-only, non-destructive operation, and the description's 'Create' is consistent. The phrase 'within a firewall schedule' adds useful scoping context beyond the annotations, clarifying that this is a nested resource creation. However, no additional behavioral details are provided (e.g., immediate application, side effects).

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, direct sentence with no filler or redundancy. It is front-loaded with the action and resource, making it easily scannable and appropriately sized for the tool's simplicity.

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 detailed schema (100% coverage), output schema presence, and annotations, the description is minimally viable. However, it lacks usage guidelines and behavioral context such as the need for an existing parent schedule or the impact of apply_immediately, leaving some gaps for a 7-parameter tool.

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 100%, with all seven parameters individually described (e.g., hour format '8:00-17:00', position weekday mapping). The description itself adds no parameter-specific meaning, so the baseline score of 3 applies.

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 action ('Create') and the specific resource ('a time range within a firewall schedule'). This distinguishes it from sibling tools like create_firewall_schedule (which creates the whole schedule) and update/delete_schedule_time_range, making the purpose unambiguous.

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 provides no guidance on when to use this tool versus alternatives, no prerequisites (e.g., parent schedule must exist), and no exclusions. The agent must infer usage context entirely from the schema and sibling tool names.

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