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

With no annotations, the description carries the full burden, and it does disclose genuinely useful operational context: the source is CoinGecko, free, and requires no API key. However, it says nothing about rate limits, caching, or freshness of the 24h figures, and the read-only nature is only implied by the 'döndürür' verb.

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 efficient sentences with the returned content front-loaded and the data-source note placed last where it belongs. No filler, though the enumerated field list is slightly dense.

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-required-param read tool with no output schema, the description substitutes for the missing return documentation by listing every field returned. The only gap is the absence of any note on data freshness or update cadence.

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%, so includeTrending is already fully documented in the schema. The description implies the trending list is part of the response but does not clarify that it can be toggled off or what happens when includeTrending is false, so it stays at the baseline for a fully-covered parameter.

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?

It states a specific verb (döndürür) and resource (kripto para piyasasının genel görünümü) and enumerates the exact payload: total market cap, 24h volume and change, BTC/ETH dominance, trending coins. That is far more specific than a sibling like get_crypto_price, though the description never explicitly names which sibling to prefer.

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 when-to-use or when-not-to-use guidance and no mention of alternatives such as get_market_summary, get_crypto_price, or get_crypto_fear_greed. The only contextual hint is the data source, which is informational rather than a routing rule.

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