divine_get_month_nakshatra_list

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false, so the safety profile is covered. The description adds useful behavioral detail about the response: one nakshatra entry per day with start/end times and lord details, which goes beyond the structured annotations.

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 two sentences with no filler. The headline action is front-loaded and the supporting sentence adds the only necessary output detail, making it appropriately concise for the tool's complexity.

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 100% schema parameter descriptions, full annotations, and an output schema, the description is nearly sufficient on its own. It names the output fields and scope, though it could have explicitly noted that location/timezone inputs are required or mentioned the month-scoped tool's relationship to non-list nakshatra siblings.

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%, so all parameters already carry descriptive documentation. The description only reinforces that the tool is month-scoped and returns per-day data; it does not need to repeat parameter meanings, so baseline 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 opens with 'Get daily nakshatra list for a given month' - a specific verb, resource, and scope. It also states the exact return content (per-day nakshatra with start/end times and lord details), which distinguishes it from single-day/current nakshatra tools and other monthly list siblings.

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 'for a given month' and 'for each day' phrasing implies the use case, and sibling names like divine_get_nakshatra versus divine_get_month_* make the context understandable. However, there is no explicit when-to-use or when-not-to-use guidance, and no alternative tool is named.

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