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

The annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description's added value is telling the agent which policy areas the payload covers, but it says nothing about whether the answer is static, whether it can be partial, or how it is structured beyond the topic list.

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?

A single front-loaded sentence that leads with the purpose and then lists the covered conditions; nothing is padded. The only cost is the full Korean/English duplication, which doubles length but serves the bilingual audience.

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 static reference-lookup tool with no output schema and a single optional param, the topic enumeration gives the agent enough to decide whether the answer it needs lives here. Only the missing routing against sibling info tools keeps it from a 5.

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?

There is one optional parameter (language) with a full enum and a 100%-covered schema description, so the schema carries the meaning. The description never mentions the language option or its default, adding nothing on top of the structured field — baseline 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?

The description names a specific resource — the required and recommended conditions for running a closed test with Doply — and enumerates the concrete topics inside it (closed track, South Korea release, minSdk, paid apps, no TWA). That is far more than a restatement of the name, though it never explicitly differentiates itself from get_service_info or search_faq.

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 is only implied: an agent can infer it should call this when it needs eligibility/precondition facts for a closed test. There is no explicit when-to-use statement, no exclusion, and no reference to the sibling tools (get_contact, get_service_info, search_faq) that could also hold related information.

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