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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds essentially nothing behavioral beyond restating that it reads all records and echoing the raw endpoint path — no pagination, result size, or return-shape context.

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 with no filler; the endpoint fragment is arguably redundant but costs little. Efficient, though it is terse to the point of under-specification.

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 two-optional-parameter list tool with no output schema, the description is minimally adequate. It does not clarify what entity types 'exchange' covers (CEX/DEX/prediction) or how results are returned, which matters given the dense family of similar exchange tools.

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 description coverage is 100% with only two optional filter parameters (chainId, enabled), each documented in the schema. The description adds no format or semantic detail beyond what the schema already provides, so the 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?

States a clear verb and resource ('Get all exchanges') plus the scope modifier 'with optional filtering'. However, it gives no differentiation from the several closely named siblings (get_exchange_cex, get_exchange_dex_chain, get_exchange_prediction, get_exchange_with_exchange_rate, get_api_exchange), so an agent cannot tell which exchange listing is intended from the description alone.

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 description says 'optional filtering' but never states when this tool is the right choice versus the other exchange-listing siblings, nor any prerequisites or exclusions. There is no routing guidance at all.

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