divine_get_malayalam_festivals

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds only that the tool 'Returns ... with dates and images,' which is return-content context rather than deeper behavioral disclosure.

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?

Two sentences, front-loaded with the action and scope; the second sentence earns its place by giving concrete festival examples and the expected output content. No filler or repetition beyond minor 'Kerala' recurrence.

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-only festival lookup with an output schema, strong annotations, and fully described parameters, the definition is largely complete. The only meaningful gap is that the description does not explain why location/timezone parameters are required for computing Malayalam festival dates, though the schema examples make invocation feasible.

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%: all five required parameters have descriptions and examples in the input schema. The tool description adds no additional meaning about how lat/lon/place/tzone affect the returned festival dates, so the schema carries the burden.

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 action and resource: 'Get major Malayalam (Kerala) festivals for a year.' It is specific and the festival examples narrow the scope, but it does not explicitly contrast with sibling tools such as divine_get_tamil_festivals or divine_get_festivals_by_date.

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?

Usage context is implied by 'Malayalam (Kerala) festivals for a year,' so an agent can infer when to use it. However, there is no explicit guidance on when not to use it or which alternative sibling tool to choose for date-based, English-calendar, or Tamil festivals.

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