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

No annotations are provided, so the description carries the full behavioral burden. It does disclose the payload contents (metadata, schemas, price), which is useful, but says nothing about authorization, error behavior for invalid canonical ids, or whether results are cached/live.

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?

One front-loaded sentence with a clear verb and an explicit enumeration of the returned artifacts. No filler or 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?

With no output schema present, the description usefully enumerates the returned fields, which is the key completeness requirement here. The remaining gap is failure/error behavior and where a canonical id comes from, but for a one-parameter read tool the coverage is close to sufficient.

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 0% and the description only repeats the notion already encoded in the parameter name (canonical_service_id, i.e. a canonical service). It adds no format, example, or source for obtaining a valid id, so it does not compensate for the coverage gap.

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 (get) and resource (one canonical AgentBroker service), and enumerates what is retrieved (metadata, input/output schemas, retail price). It implies the single-item counterpart to search_services, but never names that sibling, so the differentiation is inferable rather than explicit.

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 phrase 'for one canonical AgentBroker service' implicitly tells the agent this is a single-record lookup versus the many-record search_services, but there is no explicit when-to-use guidance, no prerequisites, and no statement about what happens if the id is unknown.

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