getExchanges

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

Discloses read-only nature, no API key requirement, and parameter limits (default/max for limit, format for quotes). No annotations provided, but description fully covers behavioral traits.

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?

Compact yet complete: main purpose first, then usage guidance, then parameter details. Every sentence adds value without redundancy.

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?

Given no output schema, description explains what each exchange includes (id, name, trust score, etc.). Covers auth, read-only, and parameter constraints adequately.

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?

Adds meaning beyond schema: explains quotes as 'comma-separated list of quote currencies for the volume figures' with example 'usd,btc', and limit with default/max values.

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?

Description clearly states 'List exchanges tracked by CoinPaprika as a list ranked by rank' with specific fields, distinguishing it from siblings like getExchangeByID and getExchangeMarkets.

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?

Explicitly tells when to use this tool ('top exchanges by volume', 'biggest crypto exchanges') and names alternatives (getExchangeByID, getExchangeMarkets).

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