A4/5.0

Behavior4/5

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

Annotations already declare this as read-only, idempotent, open-world, and non-destructive, so the safety profile is covered. The description adds a meaningful behavioral constraint not in annotations: this endpoint requires a caller-supplied API key, which is an important auth/usage fact. Minor gap: no mention of pagination or rate limits typical of 'all'-style endpoints.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two tight sentences, zero waste: the first enumerates output, the second states the auth requirement. Front-loaded with the resource and scope.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter read-only metadata endpoint with an output schema and rich annotations, the description is nearly sufficient. The only missing element is return-volume/pagination behavior for an 'all exchanges' listing, which an agent may need to know.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the only parameter (_apiKey) is fully documented in the schema, so the description correctly needn't re-explain it. Baseline 3 applies when schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (return) and resource (metadata for all crypto exchanges), and enumerates the exact fields returned (name, country, grade, trading pairs, fee, website URL). Clearly distinguishes itself from siblings like all_coins, price, and top_volume_full.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description states the auth prerequisite (own CoinDesk Data API key) but gives no explicit when-to-use vs when-not-to-use guidance. The schema's _apiKey description routes users without a key to alternatives, but the description itself leaves usage context implied.

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