Get Instances Onboarding Business Details

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so safety is covered. However, the description contributes nothing beyond that — it does not say what the onboarding business details include, whether KYC status is involved, or whether the payload can be empty pre-onboarding.

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?

The single phrase is front-loaded and free of padding, so nothing is wasted, but it is under-specified rather than concise. Brevity here costs information rather than saving it.

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 read tool with one required parameter and no output schema, the description should explain what the returned business details represent and their relation to onboarding state. It provides none of that, leaving the agent to guess at the response contents.

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% for the single required parameter instance_id, and the description does not compensate at all — it never mentions the instance identifier or its format. The only parameter meaning available comes from the schema's example and length constraints, not the prose.

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 a verb (retrieve) and a resource (business details), so the basic action is identifiable, but it adds nothing the title doesn't already say. It gives no indication of which business details or how they differ from the sibling OnboardingBusinessProfile and OnboardingOwnershipDocuments tools.

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 no guidance on when to use this tool versus the many onboarding siblings (BusinessProfile, OwnershipDocuments, Rfi), nor any prerequisite or context. The agent is left to infer everything from the name.

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