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

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds only a redundant endpoint path (GET /v1/namaz) and an unclear phrase 'Her pakette', providing no additional behavioral context such as response format, rate limits, or how the Diyanet method affects results.

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 very short and front-loads the purpose, but the second sentence ('GET /v1/namaz. Her pakette.') is either redundant or cryptic and does not earn its place.

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 tool with seven optional parameters and no output schema, the description does not explain how to combine location parameters (il, ilce, konum, enlem/boylam), what 'gun' controls, or what the returned data contains. It leaves significant gaps for an agent to infer.

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 seven parameters are fully documented in the schema. The description adds no extra semantics or usage hints beyond the endpoint path, so it meets the baseline for high schema coverage.

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 the tool provides prayer times (namaz vakitleri), iftar, and sahur using the Diyanet calculation method, which is a specific resource. However, it largely repeats the title and does not differentiate from siblings beyond the obvious domain.

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?

There is no guidance on when to use this tool versus alternatives, no prerequisites, and no mention of typical use cases. 'Her pakette' is unclear and does not help an agent decide.

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