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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is fully covered elsewhere. The description adds only the raw endpoint path, which conveys no behavioral context beyond what the annotations provide (no mention of result size, pagination, or ordering).

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 that are front-loaded with the purpose. The trailing endpoint path is largely redundant metadata but costs little.

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 simple no-arg list tool with safety annotations, this is minimally adequate. With no output schema, the description could still note the shape of the returned list (identifiers, names, count), which an agent would need to know before using the result.

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, so the schema is trivially complete and the description has nothing to compensate for. This meets the baseline for a no-parameter tool.

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 and resource ('Get all CEX exchanges'), and the 'CEX' qualifier implicitly distinguishes it from the DEX, prediction, and generic exchange siblings. However, it never names those alternatives, so the differentiation is inferred rather than stated.

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?

The scope ('all CEX exchanges') implies when the tool applies, but there is no explicit when-to-use, no exclusion, and no pointer to get_exchange, get_exchange_dex_chain, or get_exchange_with_exchange_rate. Usage is left to inference from the name.

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