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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds value beyond them by disclosing what the payload actually is — a fixed official llms.txt summary — and enumerating the topics it contains, which compensates for the absence of an output schema. It stops short of saying whether the content is static or refreshed, or how large the response is.

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?

One sentence, front-loaded with the verb and resource, with the enumerated contents carried in a compact parenthetical. Nothing is wasted and nothing essential is buried.

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 zero-parameter, read-only, non-destructive retrieval with no output schema, the description covers the essentials: what is returned and what topics it spans. A note on whether the content is static versus live, or its language, would close the remaining gap.

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?

The tool takes zero parameters, which is the baseline-4 case; there is nothing for the description to disambiguate. The description correctly implies a parameterless, single-shot retrieval.

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 specific verb ('döndürür') and a specific resource (the official llms.txt summary of the Klevero AI lesson-coach app), then enumerates its sections (what it is, target users, features, prices, privacy, FAQ). This makes the tool's output unmistakable. It does not explicitly contrast itself with siblings like klevero_konu_ara or klevero_not_getir, but the enumerated scope does the distinguishing implicitly.

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 this is the 'general overview' tool to call for orientation questions about Klevero. There is no explicit statement of when to use it, when to prefer klevero_konu_ara or klevero_not_getir, or any prerequisite/call-ordering guidance.

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