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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds useful content about what the response contains (state, amounts, deadlines, available actions), but says nothing about authentication, engine defaults, or failure modes. Adds moderate value beyond annotations.

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?

A single short sentence with no filler, and the key noun (the loan) is front-loaded. However, the brevity crosses into under-specification, which hurts other dimensions rather than conciseness itself.

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, the description does carry some of the return-value burden by listing state, amounts, deadlines and permitted actions, which is appropriate. But it omits the meaning of the required loanId, the engine default behavior, and how it relates to the prepare_* workflow, leaving real gaps for a two-parameter read 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?

Schema description coverage is only 50%: the optional 'engine' parameter is documented in the schema, but the required 'loanId' has no description anywhere, and the tool description mentions neither parameter. With a required, undocumented identifier, the description fails to 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?

The description enumerates what the tool exposes about a single loan (state, amounts, deadlines, permitted actions), which implies a read/getter, but it is a noun-phrase fragment with no verb and never explicitly says it retrieves or returns anything. An agent can infer the purpose, but only by reading the enumeration. Sibling differentiation is implicit at best — the prepare_* tools are never referenced.

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 statement of when this tool should be used, no prerequisites, and no mention of any alternative despite thirteen siblings including gage_prepare_borrow and gage_portfolio. The agent must guess whether this is the read step before a prepare_* call or something else.

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