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

With no annotations provided, the description carries the behavioral disclosure burden. 'List' implies a read-only operation, and the description explains what the returned information contains per structure. It does not explicitly state absence of side effects, but for a parameter-less list operation this is a minor omission rather than a serious gap.

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 dense sentence states the exact scope and the four dimensions covered for each item. It is front-loaded with the action and resource, and every clause adds information. Nothing extraneous is present.

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?

Since there is no output schema, the description must convey what the tool returns on its ownhj. It does so by enumerating the per-item details (requirements, seller acceptance, disqualifiers, buyer cost). The only small gaps are the lack of an explicit return format and confirmation that exactly ten structures will always be listed, but the description is still complete enough for an agent to select and 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 abb. The schema already shows additionalProperties: false with no properties, so there is no parameter ambiguity. Baseline for a no-parameter tool is 4, and the description correctly focuses on the output instead of inventing input semantics.

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 names a specific verb ('List') and resource ('the ten ways to fund a small acquisition'), and further specifies what is included for each: requirements, seller acceptance, exclusions, and buyer cost. This clearly differentiates the tool from siblings like get_structure and list_funding_providers, which target a single structure or a provider list.

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 intended use is implied by the listing verb and the content description: call this when you want an overview of the ten acquisition funding structures. However, it gives no explicit guidance on when to choose it over alternatives such as get_structure or list_funding_providers, and no 'when not to use' statements.

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