divine_get_planet_nakshatra_transit

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

Annotations already cover the safety profile with readOnlyHint, idempotentHint, and destructiveHint. The description adds useful behavioral context by explaining the output is the timing of entry/exit into each nakshatra, but it does not disclose details like timezone sensitivity or calculation assumptions.

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 compact sentences with no filler: it opens with the action, then states the output and intended use. Every clause earns its place and the most important information is front-loaded.

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 full input schema, the presence of an output schema, and the read-only annotations, the description is nearly sufficient for an agent to invoke the tool correctly. It lacks only explicit routing guidance among the many transit-related siblings, which is already penalized under usage guidelines.

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 the parameter schema already documents all 14 parameters. The description only reinforces that the tool targets a specific planet and adds no new parameter-level meaning beyond what the schema provides.

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 specific verb and resource: retrieving nakshatra transit details for a single planet, including when it enters and exits each nakshatra. It is clear and distinct from combustion or retrograde transit tools, though it does not explicitly name or differentiate among the many sibling transit endpoints.

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 phrase 'useful for fine-tuning transit predictions' implies a use case, but there is no explicit when-to-use guidance, prerequisite note, or comparison to alternatives like divine_get_grah_gochar or divine_get_planet_retrograde_transit. The usage context is only implied.

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