appstore__abonelik_fiyatlari

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety/scope profile is covered. The description adds no behavioral detail beyond that – no mention of the default limit, pagination, or what the country-by-country payload looks like. Adequate but thin against an already-informative annotation set.

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 short sentences with zero filler; the core capability is front-loaded and the usage hint follows immediately. Nothing could be trimmed without losing substance.

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 read-only lookup with fully documented parameters and no output schema, the description covers purpose and intent sufficiently for correct invocation. It could add a note on the returned price shape or per-country response, but nothing essential is missing.

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 three parameters (ulke, limit, abonelik_id) are already documented in the schema, including defaults ('Boşsa hepsi', default 200) and the source of abonelik_id. The description adds no syntax or meaning beyond the schema, so the baseline 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?

States a concrete verb and resource: it fetches a subscription's prices country by country ('Bir aboneliğin ülke ülke fiyatlarını getirir'). This distinguishes it from the sibling appstore__abonelikler (which manages the subscription itself), but the description never names or explicitly contrasts that sibling.

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?

Gives a clear usage trigger with an example question type ('Bu abonelik Türkiye'de kaça' türü sorular için), which tells the agent exactly which user intents map to this tool. It does not, however, state when NOT to use it or point to alternatives like play__abonelik_fiyatlari.

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