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

With no annotations provided, the description carries the full burden of behavioral disclosure. The phrase 'without initiating payment' implies a non-mutating behavior, which is useful, but it does not disclose other important behavioral traits such as whether it returns live or cached data, whether it requires any identifiers even though there are no input parameters, or what errors may occur.

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?

While the description is short (a single sentence), it is under-specified rather than concise. It uses vague terms ('settlement adapters', 'one universal order') that require elaboration to be useful. The entire description is essentially a single breath of text without structure.

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?

The tool appears complex enough to warrant a richer description given the cryptic name and no input schema. There is no mention of what 'inspect one universal order' means, how to retrieve the order, or how this relates to the domain. With no annotations and no description of outputs, the description is inadequate for an agent to correctly invoke the tool.

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 has zero parameters enlightened, and since there are no parameters, the description is not required to explain any. A baseline of 4 is given for tools with no parameters, and the description adds a minimal behavioral hint about non-payment, which is acceptable.

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?

The description states the tool 'describes settlement adapters' but the domain-specific term 'settlement adapters' is not defined in the description or schema. The second purpose, 'inspect one universal order', is ambiguous — 'universal order' is unexplained, and the tool name is cryptic. It does not distinguish the tool from siblings like 'gf.universal_status', 'gf.payment_status', or 'gf.execute'.

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?

There is some implicit indication of use ('without initiating payment' suggests a read-only inspection scenario), but there is no explicit guidance on when to use this tool versus alternatives such as 'gf.payment_status' or 'gf.universal_status'. The description does not state prerequisites or constraints.

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